  • Advantages, Disadvantages of Perfectly Competitive Markets

    Advantages, Disadvantages of Perfectly Competitive Markets

    In general, a perfectly competitive market is a market structure in which a large number of buyers and sellers are present. And all of them are involved in buying and selling homogeneous products at a single price prevailing in the market.

    In other words, perfectly competitive market is also referred to as pure competition, there is no direct competition between market participants. and all sell identical products for a single and equal price.

    Advantages of Perfect Competition

    You can see an explanation of the characteristics of a perfectly competitive market in this article. In addition, here are the advantages of a perfectly competitive market:

    a. Due to perfect knowledge among market participants, there is no misinformation and product knowledge is shared equally among all market participants.

    b. There are no barriers to entering a perfectly competitive market, so existing firms cannot gain the power to monopolize the market.

    c. There is no need to spend money on advertising, because the products sold are homogeneous, there is perfect knowledge of information, and companies can sell everything they can produce.

    d. There are two possibilities, namely the benefits to consumers and economic welfare.

    e. The formulation P (Price) = MC (Cost Margin) and MC = ATC (Average total cost) will occur. This means that production efficiency is well pushed and producers will improve the quality of the products they sell.

    Disadvantages of Perfect Competition

    In addition to the advantages of a perfectly competitive market, there are some disadvantages as well, namely:

    a. Because the goods sold are homogeneous, consumers feel limited in buying other products outside the homogeneous goods.

    b. It is very difficult to market a product whose brands are not that big or are not on a homogeneous product list.

    c. Limiting producers in innovating for product development because they are too satisfied and comfortable to produce homogeneous goods.

    How Realistic is the Manifestation of Perfectly Competitive Markets in the Real Business World?

    Realistically, there are very few markets or industries in the world that are perfectly competitive. For example, how can a company create a homogeneous product given that even the smallest companies engaged in manufacturing or services try to differentiate their products from other companies.

    The assumption that producers and consumers act rationally in a perfectly competitive market has been questioned by behavioral economists. A number of studies have shown that decision making by market participants is often irrational.

    Decision making can be biased and subjective when consumers and producers are faced with complex situations. This can be an interesting lesson .

    While a perfectly competitive market may be labeled unrealistic by some economists, this model still holds true in two respects; First, many primary commodity markets such as coffee and tea represent some of the characteristics of a perfectly competitive market.

    Such as the number of individual producers that exist, and their inability to influence market prices. Second, for other markets in manufacturing and services, the perfectly competitive market model is a useful benchmark against which economists and regulators can evaluate the level of competition in real markets. Also read our article The Concept of Demand and Supply in Economics.

    Conclusion

    Following is a brief review of the advantages, disadvantages, and criticisms of a perfectly competitive market. Whatever the market conditions, every market participant wants to benefit from their business.

    To achieve this, one of the steps that must be taken by each company or business person is to create a good accounting system for the company’s internal smoothness, comprehensive recording and reporting of each business transaction.

  • How to Determine Market Segmentation

    How to Determine Market Segmentation

    Like an archer athlete, a successful business can certainly determine the right target market . An archer must already know how much energy must be expended to reach the target. If the target is close, it means that there is no need to pull the arrow too far so that energy is not wasted, but if the target is far away, it certainly requires more energy to reach the target. For that we need what is called market segmentation according to “target”.

    Unfortunately in Indonesia, there are still many business people who do not know for sure the market segmentation of their products. All products owned are considered the same, can be for all circles. As a result, the business runs less focused and does not have a main target, so the resources they have are actually wasted. This is what is dangerous in business, because it can kill the business slowly.

    In fact, doing research to find market segmentation is very important so that the business can run smoothly. When the market segment has been found, the product marketing process will become easier and smoother. Of course this will affect the product sales process. The right market segmentation will make the product sell faster.

    A case in point is if you own a baby clothing company. The market segmentation you choose is of course the mothers. Then the market segmentation was further narrowed down to mothers who are pregnant or having babies. The market segmentation can be further narrowed by choosing mothers who prefer to shop online or not, have daughters or sons, even working mothers or not. The selection of this market segmentation adjusts what kind of product you have.

    In this article, you will find out more clearly the definition, types, characteristics and how to easily determine market segmentation for your business.

     

    1. What is Market Segmentation?

    Market segmentation is one of the strategies in the business world by grouping products owned according to similarities, similarities, interests and customer needs. Before marketing products for the business you run, it’s a good idea to know the types of market segmentation that currently exist, the following types:

    a. Geographic Segmentation

    This type of location segmentation is probably the most widely applied in Indonesia. For example, if the main target is Indonesia, the company will usually build a company located in Indonesia, the main goal is to be closer to consumers so that all costs can be reduced cheaper.

    These are a few ways you might think about creating a geographic segment:

    • Zip code/post code
    • City
    • Country
    • Population density
    • Distance from a certain location (like your office or store)
    • Climate
    • Time zone
    • Dominate language

    b. Time Segmentation

    This time segmentation is rarely used, but usually at certain times it can be applied. For example, photography services will be sold during the graduation season, clothes sellers will be flooded with orders when approaching Eid al-Fitr, and so on.

    c. Price Segmentation

    By using price segmentation, you can more easily consider the economic strength of our prospective customers, which are certainly different. Some can afford to buy at a high price, some are only able to buy at a low price. If the market segmentation is wide, you can apply prices to each product starting from low, medium, and high prices so that all people can enter.

    d. Demographic Segmentation

    Demographic Segmentation

    Gender, age, and income are the most widely used variables in demographic segmentation. Because it could be that the products being sold are only suitable for men, while for women it is already different. There are other products that are only specifically for adults, so you have to segment this demographic so you don’t get the wrong target.

    Some examples of demographic segmentation include:

    • Age
    • Gender
    • Income
    • Occupation
    • Family size
    • Race
    • Religion
    • Marital Status
    • Education
    • Ethnicity

    e. Psychographic Segmentation

    This segmentation includes consumer behavior in responding to product trends and stimulation. This segmentation data is difficult to determine into groups because it usually has a fairly large anomaly. The results of the data analysis presented are also more descriptive.

    These are some examples of psychographic segmentation:

    • Values
    • Goals
    • Needs
    • Pain points
    • Hobbies
    • Personality traits
    • Interests
    • Political party affiliation
    • Sexual orientation

    f. Socio-Cultural Segmentation

    Cultural segmentation pays more attention to the variables of consumer social and cultural patterns. The analyzed data can be; social class, ethnicity, societal norms within the scope of the market and the life cycle of the community.

    2. Characteristics of Effective Market Segmentation

    Before you know how to determine market segmentation, you must know the benchmarks for effectiveness in determining market segmentation. The characteristics of effective market segmentation must be;

    1. Measurable ( measurable ) , market segmentation can be measured to a certain degree, all data analysis research results must also be proven with measurable and accurate data.
    2. Affordable ( accessible ) , effective segmentation is to remove the wall between products and consumers. Products are clearly accessible to consumers.
    3. Influential ( Substantial ) , The segmentation process must also affect the business, for example, provide benefits and also affect process changes.
    4. Distinguishable ( differentiable ) , effective market segmentation is the segmentation of each element can be clearly distinguished.
    5. Realistic ( actionable ) , effective segmentation can also realize or realize your business plan.

    3. How to Determine Market Segmentation

    After you understand what market segmentation is and its types, then it’s time you know how to determine market segmentation for your business. The steps in determining market segmentation in outline are:

    1. Data collection , namely by conducting research in the form of  surveys,  discussions and also other techniques, to obtain variables for each type of segmentation.
    2. Analysis , After all the data is obtained you can process the data and analyze the results of data collection which will be adjusted to the marketing strategy .
    3. Compilation , this stage is where you group the results from the analysis and at this stage the results will be filtered, which products are suitable and which markets are suitable.

    Based on the stages above, the following are more complete stages in determining market segmentation.

    a. Define target market

    How to determine the target depends on the needs of the business you are running. You should pay attention to these three things:

    1. New Consumer , determine segmentation based on new business so you need to find new consumers.
    2. Focused Consumer , This is usually done to find customers that you already have but to support a sustainable business.
    3. Supported Consumer , This consumer is related to your supporting product  needs .

    Based on the three things above, you can refer to the types of segmentation previously discussed such as: demographic, price, time, and products to be sold.

    b. Know Consumer Problems and Needs

    The next step is to find out all the needs of potential customers, then adjust them to the products you sell. To be able to get the information, you can ask potential customers directly or by conducting a series of product tests.

    If you already know consumer problems, you can classify consumer wants, needs and problems. This is useful as a reference in making  a business strategy road map  and also product evaluation.

    c. Know Consumer Behavior

    Furthermore you can observe and analyze consumer behavior. You can pay attention to how consumers use the product, the conditions before and after using the product, and also the trend patterns associated with the product.

    consumer behavior

    d. Data Processing and Analysis

    Furthermore, you can process all consumer-related data that you have observed. At this stage you will find out the opportunity for the product that you will sell to each segmentation that you have done. Data analysis serves as a reference in determining strategies in preparing products and also marketing.

    e. Determine product marketing strategy

    Each segment must have a different marketing strategy, especially if the target market is different. So adjust the target market according to the marketing strategy. You can apply any type of marketing strategy by referring to market segmentation. For example, referring to demographic segmentation; What tools  are suitable for female consumers?

    f. Market response evaluation

    If the market strategy is already running and generating sales, you need to know the response from consumers, especially regarding the shortcomings of the product you have, record all the input that consumers give you and immediately fix it.

    Those were some explanations about how to easily determine market segmentation according to its type. In addition, good financial management is also needed to support your business to be more successful. With good financial management, your product marketing budget can be maximized. Use the help of  software for accounting to make financial management easier and more accurate.

  • SWOT Analysis: Benefits, Factors and Examples

    SWOT Analysis: Benefits, Factors and Examples

    Strengths, Weaknesses, Opportunities, Threats is an acronym for SWOT. SWOT Analysis is a strategic planning techniques that are useful for evaluating the strength and weakness , opportunities and threats in a project. Here will also be discussed about examples of SWOT Analysis for companies.

    But of course, both analysis for an ongoing project or one that is in new planning.

    SWOT analysis was first introduced by Albert S Humphrey in the 1960s in leading a research project at the Stanford Research Institute using data from Fortune 500 companies.

    The benefits of SWOT analysis are as follows

    The SWOT analysis method is the right tool to find problems from 4 (four) different sides, where the applications are:

    • How strength are able to take advantage of an opportunity that exist.
    • How to overcome the weaknesses that prevent profits.
    • How the strengths able to deal with threats that exist.
    • How to overcome weaknesses that are able to make threats become real or create a new threat.

    With the interconnectedness of these 4 factors, making this analysis makes it easy to realize the vision and mission of a company.

    SWOT Analysis

    SWOT Analysis Example

    The following is a simple example of conducting a SWOT analysis to evaluate a company’s strengths, weaknesses, opportunities, and threats.

    Strength 

    Strengths are the strengths of your business, such as quality, location, or other elements that make you superior to your competitors. List as many strengths as you can so you can see what sets your business apart from similar businesses that are similar to yours.

    1. We can respond quickly to every customer request without having to go through a long bureaucracy.
    2. We have low overhead costs, so we can offer our customers the best possible price.
    3. We pay close attention to every customer’s requests and needs.
    4. We are very flexible in handling each case and customer request.
    5. We have a good reputation in our market.

    Weakness 

    Weakness is the weakness of your business when compared to competitors. Estimate all the shortcomings you have so that when you want to do a promotion, you can find out which points have a “safe” location so that they don’t mention the weaknesses of your business.

    1. Our staff still has low ability in certain areas.
    2. Our company has limited capital.
    3. Cash flow is sometimes not smooth.
    4. The location of the office is in a less strategic place.

    Opportunity

    Opportunity is an opportunity that you can achieve after analyzing your position through the two internal factors above. Opportunities can also be determined by calculating the budget that you will spend on certain promotions or advertisements.

    1. The sector we are working in is on the rise.
    2. The government is very supportive of local companies like us.
    3. There is no intense competition in the sector we are engaged in.
    4. Only with low capital we can start a business well.

    Threat

    Simply put, external factors are things you cannot manage as a business owner. High risk requires business owners to analyze threats in order to prepare loss prevention strategies. Threat factors that must be considered are natural disasters, technological developments, competitor activities, and changes in government regulations.

    1. The rapid development of technology in this area is beyond our capabilities and may cause us to be late in adopting it.
    2. Changes to competitors’ strategies could threaten our position in this area.
    3. Lack of banking interest in financing funding for the industry we are currently working on.

    Factors Affecting SWOT Analysis

    There are 2 main factors that will influence the four basic components of a SWOT analysis.

    SWOT-Analysis

    External and internal factors that will affect the analysis of Strength, Weakness, Opportunities, Threats are:

    Internal Factors (Strength dan Weakness)

    Internal factors or factors that come from within consist of two points, namely strengths and weaknesses.

    Both will perform better in a study when strengths outweigh weaknesses.

    Thus the maximum internal strength will obviously give much better research results.

    As for the part of the internal factors themselves, including the resources owned, financial or financial, internal strengths or weaknesses of the organization, as well as previous organizational experiences (both successful and failed).

    External Factors ( Opportunities and Threats )

    This is a factor from outside the entity, where this factor is not directly involved in what is being researched and consists of 2 points, namely threats and opportunities.

    The existence of these opportunities and threats will of course provide data that must be included in research journals so as to produce strategies to deal with them.

    Several points are included in external factors, including trends, culture, socio-politics, ideology, and the economy , sources of capital, government regulations, technological developments, events that occur, and the environment.

    SWOT Analysis Combination Strategy

    In the analysis, you can focus on a combination of the two SWOT points to determine the strategic steps of your business . These focus combinations include:

    1. Focus on  strengths-opportunities (SO)  to obtain offensive alternatives by using internal strengths to take advantage of external opportunities.
    2. Focus on  Weaknesses  (WT)  to obtain defensive alternatives by exploiting internal weaknesses to reduce external threats.
    3. Focus on  Strength-threats  (ST)  by using internal strengths to reduce external threats.
    4. Focus on  Weaknesses  (WO)  by shoring up internal weaknesses to take advantage of external opportunities.

    As a method in general, this SWOT analysis can only help analyze the situation being faced by a company or an organization.

    This means that in principle this method is not a definite answer that is able to provide a solution to every problem at hand.

    But at least it will break down the existing problem by breaking it down into small parts that will look simpler.

    In addition to making a SWOT analysis, companies must also start to make a proper financial analysis.

  • What is SOP? Functions, Benefits, and Examples of SOP.

    What is SOP? Functions, Benefits, and Examples of SOP.

    Simply put, SOP are guidelines related to procedures that must be carried out. For example, in a company, company SOP are all the guidelines that employees need to do to get good work results.

    This rule itself is not only about how to get the job done. There are SOP if there is a disaster, SOP if employees are allowed to work, SOP if employees are about to change jobs, and so on.

    In essence, this SOP will arrange for everything to run properly, correctly, and effectively.

    Definition of SOP

    Simply put, as previously explained, SOP are a series of procedures that need to be carried out to get the desired results. Later, this will be a guide for employees on what they should do.

    Meanwhile, there are some experts who also have an opinion about the meaning of SOP itself. SOP are guidelines used to ensure the operational activities of a company or organization run smoothly.

    SOP is a sequence of steps in terms of implementing work, where the work is carried out. It deals with what to do, how to do it, when and where to do it, and who should do it.

    SOP function

    In its own making, SOP have several functions. At least this company SOP is a work guideline that must be obeyed by all parties.

    Try to imagine if a company does not have an SOP. So, every time there is a new employee, the employee will be confused about what they should do.

    The employee will also be confused about his duties, rights, and responsibilities. This is one of the functions of the existence of this standard rule.

    The existing SOP will be a guide for each employee to carry out their duties. Likewise, when there are new employees, the old employees do not have to bother explaining a lot of things about work culture.

    Old employees only need to explain certain things.

    In addition, this rule also has several other functions, such as:

    1. As a Work Guide

    SOP will serve as a guide when working. With this rule, it will be easier in terms of operations .

    This guide will contain the steps in doing the job. This will be very useful to assist employees in carrying out and completing their duties.

    This will also help improve the performance of the company. That’s because every job will be purposeful.

    In this case, employees will know what they need to do, what their rights and responsibilities are, what work standards the company expects, and the limits of their work.

    Furthermore, this rule will help the company to achieve its goals. And on the other hand, by applying this rule properly, the company will also help employees to work optimally.

    2. As a Legal Basis

    SOP will also serve as a legal basis. This will relate to the rights and responsibilities of each party.

    If later there is one party who violates this rule, then the punishment that that party will get is usually already stated in the rule.

    By adhering to this guide, it will also be easier for each error to find the cause.

    This is because it is enough to see which parties are working not in accordance with the existing SOP.

    3. Providing Job-Related Information

    In its application, company SOP are all rules or stages that will be related to work. Later, this company guideline is not only about procedures, but will also contain all the possibilities that occur while working.

    This includes possible problems and obstacles that will arise during work .

    The SOP will manage all the steps when this happens. In other respects, this guide will also set out what all parties need to do, in the event of a natural disaster, for example.

    4. Work Discipline Guidelines

    The essence of the contents of the SOP is the rules that need to be followed by all parties. This rule also contains the consequences they will get if they violate.

    With this, another benefit of the company’s SOP is to create work discipline.


    Purpose of SOP

    From the benefits obtained by the existence of SOP, these rules also have a purpose in making them. Some of these goals include:

    1. Minimizing Errors

    With the SOP in effect, it is hoped that every party present will follow it and understand what they need to do.

    Later, this will be one way to minimize errors.

    2. Employees Find Out More About Their Jobs

    Regarding how to reduce errors. This is partly because every employee will understand what they need to do.

    This in addition to minimizing errors can also be a way to improve the performance of employees.

    3. New Employees Will Easily Adapt

    With this guide, every new employee will be able to immediately know what their rights and responsibilities are. They will also find it easier to know about the details of the work they need to do.

    4. Helping the Company Reach the Target

    With the SOP, one of the goals is to help companies achieve the targets they set. This guide will contain guidance on how to work effectively and efficiently.

    This will be one way to help the company achieve its targets.


    SOP Benefits

    SOP itself is one thing that companies must have. In this case because these guides and guidelines themselves have many benefits.

    The main benefit is of course to provide written guidance on what employees should do. In addition, other benefits of company SOP are :

    1. Increase Reputation

    SOP is one of the characteristics of the company’s seriousness in running a business. In the client’s eyes, companies that have clear rules are considered to know what they are doing and how to do it.

    In this case, one of the benefits of SOP is to increase the reputation or good name of the company itself. When the company runs the existing rules well, the client’s assessment will be good.

    2. SOP are Guidelines for Working

    A company certainly does not want its employees confused about what they should do. This is one of the benefits of having SOP.

    With this guide, it will really help employees to work according to their respective duties and obligations. This will make the work more effective and also avoid overlapping tasks or escaping responsibilities.

    Furthermore, the guide will also make the finished work standard.

    3. SOP is a system that will make it easier

    In connection with the previous point, the SOP will also be a system that will simplify the work in many ways. For example, if an error occurs, then the process of tracing the error will be easy.

    With this guide, all parties involved will know what they have to do, what the standards are, and to what extent.

    4. Maintaining the Company’s Characteristics

    Another benefit of implementing SOP is that they can maintain the company’s characteristics. Company SOP are guidelines that all employees must follow.

    With this guide, whoever does the work will produce a product of the same quality and standard.

    This is because each employee will not work forever. So, with the company’s SOP, it is hoped that when there is a change of employees, it will not affect the quality of production.

    5. Provide Clear Rules

    With the SOP, this indirectly also becomes a rule that all parties must follow. Everyone associated with the guidelines must make it a rule.

    Later, in the guidelines themselves, there will be rules regarding parties who do not follow these guidelines and guidelines properly.

    For example, in a company there are rules that require all employees to wear uniforms.

    When there are employees who do not wear uniforms, the SOP rules will also regulate what punishments the employee will get. In this case, this guide will also be useful as a provider of clear rules.


    Tips for Making SOP

    In every SOP preparation there are at least a few things that need to be considered. One of them is a matter of principle in the formulation of the rules themselves.

    Principles in Preparing SOP

    Because of its very important function, the making of the SOP itself cannot be made haphazardly.

    At least, in its manufacture there are several principles that need to be considered. Some of these principles include:

    1. Clear and Easy to Understand

    Because it will be a guideline and many people will use it, every rule and step in the SOP must be clear and easy to understand.

    In its application, each step in this guide must contain a detailed description so that it is easy to implement.

    In addition, the making of this guide should also use simple and uncomplicated language.

    This is to avoid misunderstandings when interpreting the meaning in the guide itself.

    2. Effective and Efficient

    One of the goals of making SOP is that all parties will easily understand what they have to do. That is why, in making this rule, it must be able to make all work systems effective and efficient.

    Every work procedure in the SOP must be made efficiently. This is to maintain the efficiency of time, energy, and of course costs.

    However, this efficiency will also be closely related to effectiveness. In this case, the company’s target must be the highest benchmark.

    Simply put, in its manufacture, the company’s SOP must be made based on the company’s own goals. This rule will be a way to realize these goals in an efficient and effective manner.

    3. Alignment

    Another principle in the preparation of SOP is harmony. One of these alignments relates to the goals of the company.

    In addition, this alignment is also related to the vision, mission, resources, and also several other things.

    4. Dynamic

    In this case, the SOP can change at any time. Of course these changes occur with prior notice.

    Changes in the rules are important because they must adapt to existing conditions.

    This is where the importance of evaluating the SOP itself. Later, any existing deficiencies can be corrected and produce new, better rules or guidelines.

    5. Measurable

    One of the goals of making SOP is to help companies achieve their goals or targets. In this case, it is this goal or target that must be measurable, both in quantity and quality.

    The measurable principle in making this rule is also important, one of which is as an evaluation material. With a clear measure, it will be easy to judge whether the existing rules are still relevant or not.

    6. Open

    One other principle that needs to be considered when making SOP is openness. That means every rule must be transparent .

    Each party must know clearly all rights and responsibilities.

    This openness also means that every rule is subject to change. When the applicable rules are deemed ineffective or no longer relevant, changes can be made.

    7. Legal certainty

    In addition to work procedure problems, SOP will also usually regulate if an error occurs. In this case, it will also contain punishment.

    Every punishment that exists must of course be in accordance with applicable law.

    The SOP will also regulate if one of the parties does not follow the applicable guidelines. Furthermore, the guidelines also regulate whether an employee can be protected or not if he or she is subject to a lawsuit.

    Tips for Preparing SOP

    In addition to paying attention to the principles as above, in making SOP there are also some tips that can be one way to make effective and good rules.

    Some tips for compiling these rules include:

    1. Determining the Right Person

    You probably already understand how important an SOP is for the company. That is why the manufacturing process cannot be arbitrary.

    Therefore, the person or team that composes this rule cannot be an arbitrary person.

    In this case, besides needing people who have writing skills, making SOP also requires people who understand the technical and non-technical matters of the company.

    In some cases, company SOP are also prepared by external parties they hire.

    2. Create Interesting Visuals

    The SOP will contain many guidelines that will serve as guidelines for many people. This will cause problems if the existing guide is only available in text or written format.

    This is because some people actually understand better when they see pictures.

    In addition, the visual function of the SOP is to make people interested in reading it. A guide that contains lots of rules and guidelines will be very boring if it’s just text or text.

    3. Pay attention to the writing style

    In this case, always pay attention to who your target is. The mistake that often occurs is that the SOP is made with writing or language style that is not in accordance with the target.

    Even though they have the same goals and objectives, the guide for the engineering section cannot be the same as the guide for the finance section. This is because the understanding of each person will be different.

    If this happens, it will only cause confusion in the translation of the guide itself.

    To avoid this, it is better when making SOP each division or section participates. This is useful for equalizing understanding and also creating more detailed guidelines.

    4. Pay Attention to Work in the Field

    In this case, every SOP making must pay attention to who will use it and also how it will be implemented later.

    Also make sure if you use it later it doesn’t cause other problems.

    That is the importance of paying attention to any existing guidelines. That way, when you create a new guide, you can learn what is missing. To be repaired later.

    5. Do Testing Before SOP Launch

    It’s a good idea, before the SOP becomes a fixed rule, do a test for a certain time. This is useful for assessing whether the new rules have met expectations or not.

    In addition, this test will also assess how the response from employees or related parties. Like, whether this new rule makes it easier or makes it more complicated.

    6. Make Sure Every Rule Has A Reason

    In each rule will definitely raise questions about why you made the rule. Here, then you need to provide answers to these questions. Give a reasonable reason why the rule exists.

    Don’t let anyone think that the rules are made only to benefit the other party.

    7. Make Sure All Parties Agree

    Since the implementation of this SOP will be a shared responsibility, it is also quite important to ensure that all parties involved agree on the rules. This agreement is also to avoid the emergence of conflicts in the future.

    8. Always Review Existing SOP

    The current rules are an improvement over the previous rules. It also confirms that the current rules are still subject to change.

    This could be because the rules are no longer relevant, conditions have changed, or other factors.

    This is where it is important to always monitor any applicable rules. If it is felt that there are many shortcomings, then the rules can be immediately changed.

    Of course, each of these changes must also be known by all parties.

    SOP Example

    In its use, of course the SOP of each company will be different. This will depend on the prevailing work culture in the company.

    However, in essence, each of these rules will have the same goal.

    Here are some examples of SOP that you can learn:

    Example of Company SOP on Computer and Internet Use

    Title STANDARD OPERATING PROCEDURE FOR USE OF COMPUTER AND INTERNET
    1 Background 1. Each employee is given a computer which is the office inventory
    2. Every computer is connected to the internet provided by the office
    3. Control the use and utilization of computers and the internet in the work environment during working hours.
    2  Destination 1. Optimizing the use of computers and internet for office facilities for work purposes.
    2. Use of computer and internet office facilities for the right things.
    3 Scope Use of computers and internet for each employee
    4 Responsibility 1. IT Department
    2. Spv of each section
    3. Every employee
    5 Work Units Involved 1. IT Department
    2. Internal Audit
    6 Implementation Procedure 1. Every employee uses the office computer and internet only for work purposes and not for other purposes outside of work.
    2. Each employee is responsible for the office inventory computer that each uses.
    3. File storage on each computer is arranged as neatly as possible. Use clear folder names.
    4. Perform anti-virus scans periodically. Use an anti-virus that is already available
    5. If there is any discrepancy or damage during use, immediately contact the IT Department.
    6. If you feel the need to improve the quality of the device, then carry out the submission procedure with the knowledge of the IT Department
    7 Recording Internal memo to each division.

    Furthermore, each SOP will be signed by the maker, examiner, and those who approve.

    After the SOP is published, it will become the applicable guidelines and rules.

    Sample Company SOP on Uniforms

    In addition to the format as before, usually this rule will also be spread in a simpler format. Usually in this format, the information provided is only about the implementation procedure.

    Usually this is the format that employees see most often. Here is an example:

    STANDARD OPERATING PROCEDURE

    About: Uniform Use

    1. Every employee is required to wear the official uniform that has been determined.
    2. Every employee is required to use an ID Card while in the work environment.
    3. Each employee may only wear black or dark colored shoes.
    4. Every employee is prohibited from using excessive accessories during work.

    That’s an example of a Standard Operating Procedure for uniform use. Rules with this format are usually the ones that will be distributed and pasted in places that are easily read by many people.

    In the rules, this format usually only contains the signature of the maker or person in charge of the rule.


    In addition to the format as above, there are several other formats of making this rule. For example, using images.

    Usually this is for guidance on technical matters. By using images, the hope is that users will become easier to understand.

    In addition, the current guide format also uses audio-visual media. This is to make distributing this guide easier.

    In addition, this format is also considered more effective, because in addition to hearing and seeing directly, users can also choose to see only or only hear.

    In addition to making it more interesting, some places also make this SOP format in the form of animation. Although the format is different, but the purpose of making this guide remains the same.

    Its main goal is to make it easier for users to do what they need to do. This guideline is also useful for providing clear boundaries.

    If it is associated with company SOP, then the goal is that each party or division knows what their duties, responsibilities and rights are. Later, this will be the basis and benchmark in each of their work.

    SOP can also be a reference standard for any existing work. In addition, SOP will also be very useful to inform all parties about what they should do when something happens such as a natural disaster or fire.

  • The Position & Role of the CEO in a Company

    The Position & Role of the CEO in a Company

    You must have heard the term “CEO” before, right?

    Especially if you are quite active in socializing on professional social media such as LinkedIn, you will often come across several profiles of individuals who have CEO positions in the companies where they work.

    Whether it’s for companies whose names are already quite large in Indonesia, as well as new companies that have sprung up recently.

    The CEO position is often synonymous with the highest position in the company.

    So, what exactly is the function of the CEO position?

    Is it different from the position of director and other high positions?

    Come on, let’s look at the following brief review.

    What is a CEO?

    CEO stands for Chief Executive Officer .

    This position is the highest position in the company’s organizational structure, and is usually found in almost all startup companies .

    Usually, a startup company founder also holds the role of CEO in the company.

    However, if a company has a group of shareholders, often the position of CEO is determined by the results of the agreement of the shareholders.

    The Chief Executive Officer of a company is tasked with leading & directing the company, so that it is in line with the vision & mission that has been determined by the company owners/shareholders.

    The CEO has full control over the company’s business activities, including determining the top-level strategies that need to be carried out to develop the company.

    From his duties, the position of CEO actually has similarities to the position of the President Director and the position of the President Director.

    Qualified CEO Character

    Then, can everyone become a CEO?

    Well , because the CEO’s role is very crucial in a company, the company owners/shareholders must be really observant in choosing the CEO that fits their vision and mission.

    Here are some of the characteristics of a CEO who is usually quite reliable in managing a company:

    Able to work together ( teamwork )

    A good CEO is certainly a good team player too.

    The reason is, in leading a company, the CEO must be able to build solid teams , proficient in their fields, and able to communicate with each other.

    A CEO must also be able to be a good listener, and also know who people need to talk to if a problem occurs.

    Quick to adapt ( adaptability )

    The mindset of a good CEO should not be rigid, and be able to quickly change according to circumstances.

    Not only that, the CEO must also be able to learn from past events, and make policies that can mitigate the occurrence of undesirable things.

    Always reliable ( reliability )

    A good leader is a leader who can always be relied on.

    For example, if there is a problem with the company, a CEO must be able to show calm and maturity; not easy to panic & not easy to lose control of his emotions.

    A CEO must be able to estimate the location of the source of the problem, what things can be prepared to overcome it, and who needs to be contacted to immediately resolve the problem.

    That way, the CEO will always get the full trust of the employees, and they will always be ready to accept & carry out all the directions given properly.

    Able to see far ahead ( foresight )

    Just as a business owner is able to see future business trends , a CEO should also be able to predict the business situation in the future.

    At least for the next 1-2 years.

    For example, when the company plans to open a new branch outside the city or abroad, will this have a good impact on the company?

    Or even have a bad impact?

    A CEO needs to have the ability to understand, and read insights about the business situation in the future.

    This is useful so that companies can take advantage of opportunities and also mitigate business risks.

    Have a good character ( decency )

    In addition to the characters above, a CEO should also have a good character.

    For example, by not taking actions that have the potential to violate the law, or issuing policies that complicate the conditions and welfare of employees.

    A good CEO will always prioritize the human factor first, before making decisions related to the development of the company.

    CEO Can Be Changed?

    Then, can a CEO, whose role is very important in a company, be replaced?

    The answer is yes.

    A CEO is someone who is chosen by the owners/shareholders of the company to run the company according to their vision & mission.

    If the owners feel that there are other prospective individuals who are more experienced, or whose leadership style is more in line with the business concept, then they may appoint a new CEO to replace the role of the previous CEO.

    Usually, if a company’s growth slows down, shareholders will appoint a new CEO to improve conditions in the company.

    However, the change could also occur because the old CEO decided to resign for other reasons.

    For example, recently PT Esteh Indonesia Makmur also changed its CEO.

    Artist and young entrepreneur Nagita Slavina was appointed CEO of Esteh Indonesia last July, replacing Haidhar Wurjanto. Haidhar himself is the founder of Esteh Indonesia.

    The two CEO figures are both quite successful entrepreneurs at a young age.

    Haidhar has other food & beverage businesses such as Momo Milk, Raindear Coffee & Kitchen, Cakekekinian, Forestthree Coffee, and Esteh Indonesia.

    Meanwhile, Nagita Slavina is also experienced in managing the various businesses she owns.

    Examples include RANS Entertainment, Frame Ritz and RA Picture production houses, RANS Living, Nagita Slavina Cosmetics, and many others.

    The ability to manage various businesses and companies, as well as their business experience so far, make these two individuals who are suitable for holding the CEO position.

    Conclusion

    Like a captain who leads a ship, a CEO has an important role in a company.

    Many things and high-level strategic decisions a CEO needs to make. Therefore, it must be someone who is truly experienced who is able to carry out these tasks.

    The CEO must also be able to be a bridge between the daily operational activities of the company and the owners/shareholders of the company.

    CEO turnover is not always due to improve the company’s unstable condition. However, it could be because there are other changes that need to be made within the company.

    Whoever is chosen, whether from the business community or celebrities, as long as that person has the skills & knowledge needed, and is in accordance with the vision & mission of the shareholders, then that person is suitable to be a CEO.

  • Definition of Distribution: Function, Purpose, and Types of Distribution

    Definition of Distribution: Function, Purpose, and Types of Distribution

    Distribution is one of the processes carried out in economic activities and plays an important role in providing human needs. So what exactly is distribution, and what is its purpose?

    In this article, several things related to distribution will be discussed in full, including:

    • An explanation of what distribution is, both in general terms and according to experts.
    • Distribution function in economic activity.
    • General distribution purposes.
    • Distribution types.
    • The actors in distribution activities.

    Let’s see the article until the end, so that you better understand what is meant by distribution.

    Definition of Distribution Is

    The word “distribution” is adapted from English “distribution” which means the act or process of sending something from one party to another.

    In a business context, the definition of distribution is the process of distributing a product, be it goods or services, from producers to consumers so that the product is widely distributed and can be purchased by consumers who need it.

    There is also a mention of the meaning of distribution is a marketing activity that aims to facilitate the process of delivering products from producers to consumers. In other words, distribution is the link between production and consumption activities .

    Distribution is one of the four elements of the marketing mix. Distribution is the process of making a product or service available for the consumer or business user who needs it. This can be done directly by the producer or service provider or using indirect channels with distributors or intermediaries.

    In practice, distribution is part of the marketing process that can add value to the product through various functions such as utility, place, time, and product ownership rights.

    In addition, it also creates a smooth flow of marketing, both physical and non-physical such as the flow of information, promotions, negotiations, payments, and so on.

    Distribution activities can be influenced by several factors, including:

    • Number of products.
    • Product nature.
    • Area area.
    • Transportation facilities.
    • Means of communication.
    • company factor.
    • Cost factor.
    • Market conditions.

     

    Distribution Function in Economic Activities

    In general, there are four main functions of distribution activities, namely purchasing, classification, promotion, and distribution. Here’s a full explanation:

    1. Product Purchase

    The activity of purchasing goods is the initial process of distribution produced by producers. However, if the distribution of goods from producers is carried out directly to consumers, then this process does not apply.

    2. Product Classification

    After the process of purchasing goods, there will be an activity of classifying goods based on their function and type so that marketing and counting goods becomes easier.

    3. Product Promotion

    After the goods are classified, there will be a process of promoting the goods, namely introducing the goods to the public. The process of promoting this item can be done by installing displays in store windows, advertising in various media, and direct offers to consumers.

    4. Product Distribution

    This is the main activity of distribution, namely distributing goods to consumers. The distribution process must be carried out quickly and precisely so that distributors benefit from distribution activities.

     

    General Distribution Purpose

    The main purpose of distribution activities is to ensure the continuity of production activities and ensure that the product is well received by consumers. Here’s a full explanation:

    1. Ensuring the Continuity of Production Activities

    A well-run distribution process will help production activities. By carrying out distribution activities, the products that have been produced are not held in the producer’s warehouse but move into the hands of distributors.

    2. Ensuring Products Get to Consumers

    In accordance with its main objective, distribution activities will ensure that products from producers can reach consumers. This distribution process can be done by introducing goods (promotions) to the process of sending goods to consumers.

     

    Distribution Types

    Based on the role of producers with consumers, the types of distribution can be grouped into two, namely direct distribution and indirect distribution. But apart from that, there are also intensive, selective, and exclusive distribution types.

    The following is a brief discussion:

    1. Direct Distribution

    The definition of direct distribution is an activity of distributing goods from producers directly to consumers. In other words, producers act as distributors and the distribution process does not go through intermediaries or third parties.

    In practice, companies must consider the amount of investment required to implement a direct distribution strategy. For example, adding warehouses, vehicles, and delivery staff to distribute goods yourself effectively.

    2. Indirect Distribution

    The definition of indirect distribution is an activity of distributing goods from producers to consumers using intermediaries or third parties. In this case, the distributor can be an individual or a distribution company.

    The term “intermediary” often gets a bad reputation, but in the case of distribution, intermediaries can help in the process of delivering goods to consumers.

    Indirect distribution strategies involve intermediaries who assist with logistics and product placement so that they can reach customers quickly and in optimal locations based on consumer habits and preferences.

    3. Intensive Distribution

    This type of distribution is done by sending the product to as many retail locations as possible. However, only certain products are suitable for this method, namely products that are easy to sell. For example, cold drinks that require very little effort to sell.

    4. Exclusive Distribution

    Exclusive distribution is carried out by producers by entering into agreements with retailers, namely selling products only through special storefronts. One example of exclusive distribution is the agreement between Apple and AT & T in the distribution of iPhone products in America.

    This distribution strategy is very suitable for exclusive products that are in demand and eagerly awaited by many people, such as the iPhone.

    5. Selective Distribution

    Selective distribution is a middle ground between intensive and exclusive distribution. This type of distribution is done by distributing the product in more than one location, but not as much as with intensive distribution.

    For example; selectively selected well-known clothing products such as the Exclusive clothing brand. In addition to the store itself, products from the Exclusive brand can also be found in several clothing stores.

     

    Distribution Actors in Economic Activities

    Based on the distribution of goods from producers to consumers, distribution actors (distributors) can be divided into six groups, namely:

    1. Merchant

    Merchants are parties who buy goods from producers and resell them to final consumers. Traders can determine the selling price of a product according to market conditions and socio-economic conditions in a society.

    2. Agent

    Agents are companies that have the responsibility to distribute goods from producers to consumers. The profit obtained by the agent is from a predetermined commission value.

    3. Realtor

    A broker is a party that brings together producers and potential buyers of a product, be it goods or services. The broker does not spend any capital in the distribution process and the profits obtained are in the form of fees from producers and consumers for their services.

    4. Exporter

    Exporters are parties who distribute goods from domestic producers to consumers abroad.

    5. Importer

    The opposite of exporters, importers are parties who distribute goods from abroad to consumers in the country.

    6. Commissioner

    The commissioner is a party who makes purchases and sales on his own behalf.

     

    Conclusion

    From the explanation above, we can conclude that the definition of distribution is the process of spreading a product throughout the market so that the wider community knows it and can buy it.

    The distribution process involves the following:

    • Good transportation system to carry products to different geographic areas.
    • A good tracking system so that the product can be sent to the right party, at the right time, and in the right quantity.
    • Good packaging in order to protect the product during the shipping process.
    • Keep track of places where products can be marketed so that sales opportunities are better.
    • A good system in retrieving goods from traders.

    Thus a brief explanation of distribution, starting from its understanding, function and purpose of distribution, types of distribution, as well as several factors that influence the distribution process. Hopefully this article is useful and adds to your insight.

  • Integrated Circuit (IC) : Definition, History, Functions, Types and Examples

    Integrated Circuit (IC) : Definition, History, Functions, Types and Examples

    Do you know what IC is? In general, IC is an important component that we often find in an electronic circuit.

    This time, we will discuss in more detail what IC is. Starting from understanding, history, types, functions, and also examples.

    So, don’t miss the complete information below, okay?

    What is IC / Integrated Circuit ?

    What is IC

    IC stands for Integrated CircuitBriefly, the definition of IC is an active electronic component . Which in it consists of a collection of thousands or even millions of resistors, transistors, diodes and capacitors.

    All of these elements are assembled into one electronic component and then integrated in a small package that we know as an IC.

    In terms of language, this IC is usually referred to as an Integrated Circuit. To make it, you need semiconductor materials in the form of silicon.

    IC serves as a logic gate whose job is to control a circuit. When using IC, the electronic device will have a small or portable form. This is why the appearance can be more concise, practical and more modern.

    history of Integrated Circuit

    IC history

    IC invented by whom?

    IC history was first introduced in 1958. This technology was introduced by a worker from Texas named Jack Killby.

    After being introduced for the first time, six months later IC was re-developed with a more sophisticated format than before.

    Robert Noycer is a person who succeeded in making IC fabrication. Which IC is made with a system connected to a silicon chip.

    With this discovery, IC is known as a popular technology and continues to grow rapidly from time to time.

    This IC is very influential on the appearance of today’s electronic equipment. Just imagine, how big the old electronics were because they still used vacuum tubes as their basic components.

    Now with the IC, almost all electronic equipment today has a thinner and more practical form.

    But not so when IC technology was invented. Some electronic devices have had significant changes.

    As we can see now, electronic equipment such as mobile phones, laptops or televisions have a slimmer and lighter form.

    In addition, IC technology is also proven to be able to make electricity consumption much lower.

    Therefore, nowadays almost every electronic component uses IC technology as its main internal part.

    What is the functions of IC?

    What are the functions of ICs?

    As we discussed above, IC is the main component used for electronic circuits .

    The IC functions for electronic devices are divided into 3 parts, namely:

    1. Linear IC
    2. Digital IC
    3. Mixed IC

    The following is an explanation of the IC functions of the 3 parts above, namely:

    1. Linear IC

    Linear IC

    Linear IC is also known as Integrated Circuit Analog. This linear IC can only operate on a continuous waveform signal.

    Here are some functions of the linear IC that you need to know.

    • Power amplifier (power amplifier).
    • Micro signal amplifier (microwave amplifier)
    • voltage regulator (voltage regulator)
    • RF and IF amplifier (RF And IF amplifier)
    • Multiplier
    • Voltage comparator
    • Radio frequency reception (radio receiver)
    • Operational amplifier
    • Signal booster and so on.

    2. Digital IC

    Digital IC

    igital IC is a type of IC that is popular for its use in the latest electronic equipment. For example, ICs are embedded in calculators, smartphones and laptops.

    These digital ICs generally have input and output voltages. Where each voltage has two levels, namely high and low. As for binary code, generally use the symbols of the numbers 1 and 0.

    The tasks and functions of digital ICs are as follows.

    • As a logic gate.
    • flip-flop
    • Timer
    • Counter
    • multiplexer
    • Memory
    • Calculator
    • Microprocessor and so on.

    3. Mixed IC

    Mixed IC is a type of IC that consists of a combination of analog IC types and digital ICs. The main function of the Mixed IC is to convert from analog signals to digital signals and vice versa.

    As technology develops, mixed ICs are also used for digital signal integration and RF functions.


     the Types of IC

     the Types of IC

    Having previously known about the various functions of IC, then next we will discuss about the types of IC. Let’s look at the explanation of the following IC classification.

    1. Transistor Transistor Logic (TTL)

    Transistor transistor logic (TTL) is a type of digital IC that is quite widely used in electronic circuits. Because the TTL IC has a relatively low voltage source. That is only about 4.75 volts to 5.25 volts.

    TTL ICs are built using transistors as the main element. The function of the transistor in this case is as a logical variation, so it is often referred to as Transistor Logic.

    In TTL ICs, several transistors are combined into one. So that it forms two states, namely on / off or functioning as a switch .

    TTL ICs also have multiple logic gates. Where each gate has a different function. These include AND, NAND, OR, NOR, and XOR. In addition, this component also has several other logical functions.

    For example, such as econder, multiplexer, decoder, and also memory.

    2. IC-CMOS

    2. IC-CMOS

    IC-CMOS stands for complementary with MOSFET. Which, the CMOS IC consists of a combination of MOSFETs. IC-CMOS uses a square wave.

    Where the waves used are generally in two conditions. Namely points 1 and 0 which function as a switch.

    The function of the IC-CMOS is as a logic gate. Where when using it, the electronic circuit can function automatically.

    IC-CMOS can usually function optimally when given an electric current of 12 volts. In this type of IC, there are several functions of logic gates.

    Among them are AND, NAND, OR, NOR, and XOR functions. Then there are also other logic functions such as multiplexer, decoder, econder and memory.

    3. Linear IC

    Linear ICs are not included in the category of digital ICs. This is why linear ICs and digital ICs work differently. If the digital IC usually uses a contact signal, then this linear IC uses a sinusoidal wave.

    The sinusoidal wave contained in the linear IC functions as an amplifier or amplifier. So, the IC does not have a function as a logic gate. Because its main function is specifically designed as a voltage amplifier.

    Linear ICs in general also have a proportional circuit. So, it is balanced in order to produce an output that is proportional to the input value. An example of the application of a linear IC is that it is used as an operational amplifier.


    Advantages and Disadvantages of IC

    IC is an electronic element that has many advantages and benefits. However, in addition to having advantages, these electronic components of course also have disadvantages.

    What are the advantages of using IC and what are the disadvantages? Check out the full review below!

    1. Advantages of IC

    Here are some of the advantages of IC in electronic circuits are:

    • IC has a much larger size.
    • Has a light weight.
    • Can be produced simultaneously or in large quantities so that the selling price can be cheaper.
    • Soldering and interconnecting ICs with very few IC internal components.
    • The use of electrical power can be smaller and of course efficient.
    • Easier to replace and repair if there is damage.
    • Suitable for operating systems with low signal.
    • Can perform complex functions and work systems.

    2. Lack of IC

    In addition to having many advantages, IC also has several disadvantages. Among the disadvantages of IC are :

    • The IC can only be operated on low-voltage systems.
    • IC cannot trigger or generate high power.
    • ICs need to be handled with care as they are very sensitive to Electrostatic Discharge.
    • IC is not resistant to high temperatures. This is why a fan or heatsink is needed to lower the temperature around the IC.
    • Tolerance to voltage is very small and limited.

    Conclusion :

    In short, IC is an electronic component that contains thousands of transistors, diodes and capacitors. Technically the IC functions as a logic gate to control an electronic circuit.

    With the IC technology, electronic devices have a significant improvement. Among them are slimmer, portable and also compact. In addition, the IC also saves electrical energy. So that its use is very popular until now.

    Well, how? Do you understand what IC is? See you on the next material about electricity.

  • What Are Economic Bubbles, How To Avoid Them?

    What Are Economic Bubbles, How To Avoid Them?

    The term economic bubble or often also referred to as a speculative bubble or financial bubble. This is one thing to watch out for, especially when you invest.

    Determining investment instruments is not an easy thing. Of course, everyone hopes that the chosen investment instrument can increase in price so that it will provide benefits in the future.

    There are many things that must be considered so that you are not wrong in choosing an investment instrument. One thing that is quite important and needs to be watched out for is the phenomenon of the economic bubble.

    Because this phenomenon can make the value of the investment instrument you choose fall very deeply. So instead of getting a profit, you will actually experience a large amount of loss.

    Understanding the term bubble economy

    The phenomenon of economic bubbles has occurred in many countries and has a long history. The occurrence of this phenomenon makes many people suffer losses in very large numbers.

    The term economic bubble itself refers to the condition of rising asset prices to become unrealistic. Furthermore, the price of these assets experienced a sharp decline in a very fast time.

    So that people who have bought assets at high prices, suffer losses due to the decline in prices. This phenomenon can occur in various assets such as stocks, property and other types of assets.

    The naming of this phenomenon takes from the reality of bubbles that easily rise to the top. But at a certain point, the bubble will burst very quickly.

    This illustrates how the price of an asset can soar to the point of being unrealistic. Until in the end the value of the asset broke and the price fell to a very low level.

    The term economic bubble has been known by economists as something to be wary of. Because the occurrence of this phenomenon will have an influence on macroeconomic conditions.

    There have been many examples of economic crises caused by the economic bubble phenomenon. One of them is the housing bubble that occurred in 2005 – 2008 in the United States.

    In that year, house prices in the United States experienced a very high increase. Until finally in 2008, the bubble burst and caused an economic crisis.

    Until finally the American government had to bail out or provide bailout funds to help some companies keep operating. Without the bailout funds, there will be massive layoffs.

    Understanding Some of the Causes of Economic Bubbles

    In general you have understood the term bubble economy. In fact, this phenomenon refers to the movement of the price of an asset that increases and then at some point will break.

    Economists still do not know the exact cause of this phenomenon. However, there are several things that may be the cause of this phenomenon, namely as follows.

    Excessive Liquidity in the Financial System

    The first thing that may be the cause of an economic bubble is excessive monetary liquidity in the financial system. Simply put, the ease of getting a loan can be the cause of an economic bubble.

    Again remember that the term bubble economy refers to a condition in which asset prices increase to the point where it becomes unrealistic. The ease of getting a loan is one of the causes of this.

    With the ease of getting a loan, the purchase of an asset will increase. According to the law of supply-demand, more demand will make the price of an asset increase.

    At a certain point, the price of the asset becomes unaffordable so it cannot be sold. As a result, the owners of assets will make sales at low prices.

    This is done so that they still get income even though they have to suffer losses. Because on the other hand, they still have debts that have the potential to default.

    Investors’ Speculative Behavior

    One of the possible causes of the economic bubble phenomenon is the speculative behavior of investors. Because it refers to the term economic bubble, that in fact an increase in asset prices is an expected thing.

    The higher the potential increase in the price of an asset, the more attractive it will be. Because these assets are predicted to be able to provide huge profits in the future.

    Therefore, an asset that is considered to have a high price in the future must be in great demand. So that more and more investors invest in these assets and make the price increase.

    However, if the price increase is not accompanied by an increase in the intrinsic value of the asset, it will have a bad impact. Because in the end, people will realize that the asset price is too expensive.

    So the demand for these assets will decrease which will also lower the price. So investors who have bought assets at high prices will experience losses.

    The Greater Fool Theory

    One theory that is considered to be the cause of the economic bubble is the greater fool theory This theory is in line with the term economic bubble which describes a significant increase in asset value.

    In general, this theory states that price increases occur when someone can sell an asset that is overpriced to a “stupid” person. Then the “stupid” person will sell it back to the “stupider”.

    This will continue until the price of an asset becomes very high. Until finally the last person could no longer find a “stupider” one to buy the asset.

    So that the bubble will burst and make asset prices that were very high fall very low. So the last “stupider” person will receive a large amount of loss.

    Extrapolation

    Extrapolation is the behavior of equating historical data in the past with the future. This could be the cause of the economic bubble phenomenon considering that the term economic bubble is closely related to price increases.

    Indeed, one way to predict the value of an asset is to look at historical data. However, historical data is not the only data because there are other aspects that also need to be taken into account.

    Extrapolating behavior does not take this into account. They only see that the value of an asset in the past can rise to a very high which may also happen in the future.

    At some point, investors will realize that these assets cannot provide the returns as in the past. So that the bubble burst was marked by a decrease in asset prices.

    Lack of Community Financial Literacy

    It is undeniable that today many people are starting to realize the importance of investing. Unfortunately, awareness of investment is not accompanied by good financial literacy.

    In fact, one of the possible causes of the economic bubble is the lack of public literacy regarding the financial world . In fact, there are still many people who do not know the term economic bubble.

    This lack of literacy or knowledge will certainly affect people’s decisions to invest. One of them is in determining the right instrument and can provide benefits in the future.

    People who are minimal in financial literacy tend to make decisions on a whim and without careful consideration. As a result, they are more easily trapped in the economic bubble phenomenon so that they will get losses in the future.

    Tips to Avoid This Phenomenon

    After understanding the term economic bubble and its causes, of course you need to avoid this phenomenon. Because the losses that can be received due to the economic bubble phenomenon can be very large.

    There are several ways you can do to avoid this phenomenon. Here are some tips that can be done so as not to get caught in an economic bubble.

    Perform Fundamental Analysis

    One of the techniques in investing is fundamental analysis. This technique is done by choosing investment instruments that have good fundamental values. Of course, the fundamental value must be in line with the asset price.

    Fundamental analysis techniques are usually used in stock selection. This method is done by looking at the company’s performance and assessing whether the stock price is in accordance with that performance.

    But you can apply fundamental analysis techniques not only to stocks. Various other assets also have a fundamental value or intrinsic value on which the price of the asset is based.

    Given the term economic bubble is an increase in the value of prices to be unrealistic, then it doesn’t matter as long as the price increase is reasonable. This means that the price increase occurs because the intrinsic value increases.

    Don’t follow

    One of the problems faced by investors, is the fear of making decisions. So many investors prefer to follow the steps or decisions of other investors.

    This is what makes signaling groups very popular  because it makes investors not have to think. The decision to buy or sell an asset simply follows the signals given in the group.

    Whereas decisions that only follow the words of others are very vulnerable to bad effects. Because the decision could be wrong and was done to increase the price of a particular asset.

    People who are not familiar with the term bubble economy are often used for things like this. When the bubble has burst, then of course the one who feels the loss is yourself.

    Improve Financial Literacy

    Improving financial literacy is a must to avoid the economic bubble phenomenon. Apart from exploring the investment world, you also need to learn other things such as financial management and macroeconomics.

    Because basically, economic activities around the world are interconnected. For example, economic conditions in the United States can have an impact on the economic conditions of other countries.

    In addition, it is very important for you to study the economic history of the world. So you can take lessons from history and use them for consideration in the present.

    Moreover, the term economic bubble itself is not new. There has been a lot of history from various countries in the world that you can use as a lesson to be able to avoid this phenomenon.

    Avoid Excessive Desire (Greedy)

    One of the problems that must be avoided by investors is greed. Because greed will make you want the maximum profit to ignore various aspects that must be considered.

    Especially now that there are many investment instruments that promise too sweet but end up losing. Excessive desire or greed will encourage you to get stuck in such an investment instrument.

    Usually when feelings of greed arise, then someone will forget the term economic bubble. When they see an asset experiencing a rapid increase in price, they buy it without thinking.

    As a result, when the bubble burst, they were trapped because they had bought at a high price. Even worse, they can’t sell the assets, so they lose all their investment capital.

    One of the things that investors should be wary of is the economic bubble. Especially considering the term economic bubble that makes people suffer huge losses.

  • All parts of the microscope and their functions

    All parts of the microscope and their functions

    The microscope is an important part in the laboratory, but do you already know all the parts of the microscope and their functions? Actually this tool is quite familiar to know and use. It has even started at an early age, aka students. But not necessarily already know all the parts. Though every part of the microscope has an equally important role. Curious what the parts and functions are? Check out the full explanation with GeneCraft Labs below.

    Types of Microscopes

    Before entering into an explanation of the parts of a microscope and their functions, you should first get acquainted with the types. In total there are two types of microscopes, namely light and electron microscopes.

    Light microscopes are further divided into two, namely dissection microscopes which are useful for observing the surface of objects, and monocular and binocular microscopes for observing the inside of cells.

    A monocular microscope has only one eyepiece. In contrast, a binocular microscope has two eyepieces that can be used by both eyes at once.

    For the electron microscope itself, the way it works is by using an energy source from electrons to enlarge the image of the research object.

    All parts of the microscope and their functions

    Microscope Components and its function

    Now it’s time to get into the discussion of the microscope parts and their functions. The microscope itself consists of two parts. There are optical and mechanical parts.

    Optical Parts

    For the optics, there are four components in it. Consist of:

    1. Ocular Lens

    The eyepiece, which is located directly above the microscope, is the first source of vision for the user. Its function is to form a real image of the objective lens. The number of ocular lenses in a monocular microscope is only one, so it can be used by one eye. However, for the ocular lens in a binocular microscope, there are two so that the user can have both eyes at once.

    2. Objective Lens

    The objective lens is located close to the object. The function of this lens is to enlarge the image of the observed object from 10 times to 100 times.

    3. Spotlight

    The reflector is a regulating mirror that is useful for reflecting light into the diaphragm.

    4. Condenser

    The condenser is useful for collecting the light reflected by the regulating mirror. The light is focused on the object.

    mechanical part

    For the mechanical part, it consists of seven components, namely:

    1. Microscope Tube

    The microscope tube is useful for adjusting the focus. Then another function is the link between the objective lens and the eyepiece.

    2. Revolver

    The revolver functions as a lever to support the objective lens in order to make it easier to adjust the observation value of the microscope.

    3. Object Clamp

    The object clamp is useful for holding the object glass so that it is easy to move during the observation process.

    4. Diaphragm

    Diaphragm is a component that is located in the preparation table. Its job is to determine how much light enters and is focused on the object of observation.

    5. Object Table

    As the name implies, the object table is useful as a container for placing observation objects. Usually there is an object clamp as well so that it can hold the object so it doesn’t move easily during the observation process.

    6. Microscope Arm and Leg

    The arm of the microscope is a handle when you want to move the microscope. On the other hand, the foot of the microscope is useful for placing this laboratory instrument on a plane that is not flat.

    7. Joint Inclination

    The inclination joint is useful for adjusting the degree of tilt of the microscope. This component is certainly needed to make it easier to observe.

    So that’s the information about the microscope parts and their functions. Hopefully the information can be useful for you.

  • How Induction Stoves Work

    How Induction Stoves Work

    How Induction Stoves Work, Superior and Safe Electric Stoves. Induction cookers heat cooking utensils placed on them directly by magnetic induction. Cooking utensils do not get hot because the surface of the stove is hot like on a gas stove. But the heat is directly flowed into the cooking utensil which makes the food in it cooked. So, the surface of the stove is not hot, it is safe to touch.

    Induction Stove Components and Their Functions

    There are several main components in an electric stove. These components also have their respective roles. Are as follows :

    1. thermostat

    The function of this component is to regulate the temperature of the electric stove. With this component can be determined how high the desired heat temperature when cooking.

    2. Control Knob

    This component is useful for disconnecting the electric stove from the power source. The form of a button can be a touch screen or a regular button.

    3. Timer

    The advantage of electric stoves is the presence of a digital timer. From this component, you can set a warning for the length of time required to warm up.

    4. Halogen Coil/Lamp

    A coil is a kind of wire that is able to convert electric current into heat. The mechanism of action uses the principle of electromagnetic induction. While the halogen lamp uses the principle of heat radiation.

    5. Fuse

    Induction hobs use a series of fuses to protect the heating element. This fuse will blow if too much electricity flows through it. Its main function is to prevent spikes from reaching the heating element.

    How Induction Cookers Work

    The working principle of the induction cooker can be explained as follows

    1. When the stove is connected to a regular power source with a frequency of 50 Hz. Using the converter and controlling element, the mains frequency of 50 Hz is converted into a high frequency of up to 25 kHz (the frequency can be adjusted via the controlling element).
    2. This high-frequency electricity is supplied to the induction coil, then current flows through the coil. Keep in mind here that the current flowing into the induction coil is alternating current with high frequency.
    3. This alternating current generates magnetic field lines. This magnetic field always changes according to changes in the current, namely ac.
    4. This magnetic field cuts the cooking place (container) made of metal (conductor). What happens when metal is cut by a magnetic field that changes all the time?
    5. In metal, there will be an induced emf (voltage) ( Faraday’s law ).
    6. Because the metal for cooking is a single unit, it is electrically the same as being short- circuited. What happens when the voltage is short-circuited? There will be a current which in this case is rotating in direction. Because of its direction, this current is then called an eddy current or eddy current .
    7. The eddy current that flows in the metal and the metal still contains a resistance even though it is small, so heat arises and this heat is used for cooking.

    The heat generated by the stove depends on the electrical energy converted to heat. The power of the stove will be determined by the frequency of the electricity supplied to the induction coil. The higher the frequency, the higher the power of the stove and the higher the temperature (heat) of the stove.

    How it Works Induction stoves do not produce fire, there is no risk of exploding if the gas cylinder is not installed properly like on a gas stove. The surface of the induction cooker is also not heated, so it is safe to touch.

    The Kanahome induction stove is equipped with a sensor to stop the heating process if the temperature on the surface of the stove is too hot or if no cooking utensils are placed on the stove, there is also a timer feature so that the stove will turn itself off within the set time.

    The heat generated by induction stoves is more efficient than gas stoves. The flat shape makes the heat received by the cookware more evenly and 90% accepted by the cookware. While the gas stove produces uneven fire, sometimes the fire is large in certain parts so that the heat is only on a certain side, the heat received by the cooking utensils is only 65-70%. Therefore, cooking with an induction cooker is also faster and more efficient. In addition, the bottom of your pan will not turn black from being exposed to excessive heat.

  • HOW DOES A STEAM ENGINE WORK?

    HOW DOES A STEAM ENGINE WORK?

    In this article, you will learn what the components of a steam engine are and how they work. Steam engine is a technology that converts heat energy into motion energy. The steam engine has a way of working using physical concepts that apply the laws of thermodynamics.

    Inventor of the Steam Engine

    We know James Watt as the inventor of the steam engine in the mid-18th century. In that year, the invention of the steam engine became one of the most revolutionary inventions in history because it revolutionized the industrial world. The invention of the steam engine was the beginning of the industrial revolution.

    But in fact, James Watt was not the first inventor. James Watt made repairs to the previous steam engine on the condenser and shaft parts.

    So who invented the steam engine? So the answer to the inventor of the steam engine is Thomas Newcomen. The steam engine invented by Thomas Newcomen in 1712 had the purpose of pumping water in the mining world. While James Watt made repairs in 1776.

    After improvements by James Watt, the steam engine operated more efficiently and moved more smoothly in its energy conversion process. Through its improvements, the steam engine can be applied in industry more efficiently.

    James Watt worked with Matthew Boulton to design steam engines for industries in Europe.

    Not only for industry, the use of steam engines is increasingly developing as a means of supporting land transportation. Steam engines began to replace animal power during the industrial revolution, one of which was the steam locomotive. Animal power began to be replaced by steam engines in 1830 when there was a race between horses and steam engines.

    In the early 19th century, the steam engine underwent continuous improvement until it became more efficient with a smaller size.

    Steam Engine Components

    The working principle of a steam engine can occur because the components are interconnected into a system. The components of a steam engine consist of frames, pistons, cylinders, bearings, valves, etc.

    Steam Engine Components

    1) Frame

    Steam engine has a frame or frame that has a function as a container to connect the components in it. A steam engine frame is made of metal casting material because it is more resistant to thermal expansion.

    2) Cylinder

    Component Cylinder or cylinder on a steam engine is a part or component in the form of a room that has a function to accommodate steam and piston movement. Some engineers refer to the cylinder on a steam engine as the crankcase.

    3) Steam Chest

    Steam Chest on a steam engine is a part or component of a steam engine that is integrated with the cylinder. This Steam Chest generally has a cube or spherical shape depending on the valve used.

    4) Main Bearings

    Bearing is a component or part of a steam engine that has a function to maintain the rotating axis of a shaft. Because friction or flexion often occurs, the inner bearing surface needs to be coated with lubricant.

    5) Piston 

    piston in the steam engine has a similar way of working like the piston in a car engine or motorcycle engine in general. The piston in the steam engine has a function to continue the steam compression force into rotation.

    6) Piston Rings or Piston Rings

    A piston has rings to keep steam from penetrating between the pistons and cylinders.

    7) Piston Rod or Piston Rod The piston

    rod in a steam engine has a function to transmit the compressive force on the piston head to a rotary crank.

    8) Stuffing Box

    The Stuffing Box on the steam engine has a function as a seal to prevent the steam in the system from escaping into the atmosphere. If a leak occurs, the energy in the steam engine system will not be maximized.

    9) Crosshead

    Crosshead on a steam engine has a function so that the movement of the piston is not sideways and out of line.

    10) Connecting Rod or Piston

    Rod Connecting Rod on a steam engine has a function to connect the piston to the crankshaft.

    11) Valve / Valve

    As previously explained that the valve is a part of the cylinder and steam chest. The valve on the steam engine has a function as a gate for the entry and exit of steam in the system.

    12) Valve Rod and Eccentric Rod

    Eccentric Rod The machine has a slab-like shape that has the function of converting rotary motion into linear motion. Why do we need linear motion in steam engines? The answer is to open and close the valve.

    13) Flywheel

    Free Will or we call it the gear on a steam engine is a mechanism to dampen the rotation suddenly. So that the torque on the steam engine becomes more stable.

    How Does Steam Engine Work?

    Steam engines are included in the category of heat engines, namely equipment used to convert thermal energy from fuel into mechanical energy through the combustion process. There are two types of heat engines, namely Internal Combustion Engines (ICE) and External Combustion Engines (ECE). In ICE-type heat engines, the process of burning fuel to produce mechanical power is carried out within the equipment itself; while in ECE, this equipment only converts thermal energy into mechanical energy while the combustion process is carried out outside the equipment.

    Examples of ICE-type heat engines are gasoline and diesel engines, which are very popular as prime movers for both automotive and industrial use. In gasoline and diesel motors, the process of burning fuel (gasoline/diesel) is carried out in the motor cylinder itself and the change in thermal energy resulting from combustion into mechanical energy is also carried out in the aircraft itself through the back and forth movement of the piston into rotational movement of the crank shaft.

    Examples of ECE-type heat engines are steam engines and steam turbines. In this equipment, the steam engine only converts the potential energy of the steam into mechanical energy in the form of to and fro movement of the piston and then converted into rotational motion of the crank shaft; while the steam turbine converts the potential energy of the steam into mechanical energy which is directly the rotational motion of the turbine axle. The fuel combustion process is carried out outside the steam engine and steam turbine, namely in the boiler (boiler). In the boiler (boiler) the thermal energy from the combustion of fuel is used to heat water so that it turns into steam with high temperature and pressure, then the steam with high temperature and pressure is flowed to a steam engine or steam turbine to be converted into mechanical power.

    The workings of the steam engine are as follows: See the picture below,

    HOW DOES A STEAM ENGINE WORK

    Inside the steam engine cylinder there is a piston which has a piston rod connected to a cross head which is outside the cylinder. The cross head is connected by a connecting rod to the crank shaft (not shown in the picture), so that when the piston moves to and fro, the crank shaft can rotate.
    The slide valve which has a valve rod is driven by the crank shaft through an eccentric, so that the slide valve can move to and fro while opening and closing the two steam holes connected to the cylinder. The valve box where the slide valve is located has two channels, the intake channel is connected to the boiler to deliver high pressure steam (red color), and the exhaust channel is connected to the chimney to remove used steam (blue color).

    When the piston reaches the leftmost position, the slide valve will open the steam hole of the left cylinder so that steam from the boiler can enter the cylinder on the left side of the piston and push the piston to the right, while the right steam hole is connected to the exhaust channel so that the used steam can be drained. discharged through the chimney. Before the end of the piston stroke, the steam hole is closed by the slide valve so that the steam supply stops but the piston continues to move to the right due to the expansion of the steam.

    When the piston reaches the far right position, the slide valve will open the steam hole of the right cylinder so that steam from the boiler can enter the cylinder on the right side of the piston and push the piston to the left, meanwhile the left steam hole is connected to the exhaust channel so that used steam can be wasted. through the chimney. Before the end of the piston stroke, the steam hole is closed by the slide valve so that the steam supply stops but the piston continues to move to the right due to the expansion of the steam.

    Because the cross head with the crankshaft is connected by a connecting rod, the back and forth movement of the piston will be converted into rotational motion of the crankshaft. Thus as long as there is a supply of steam from the boiler, the steam engine will turn into mechanical power with the rotational movement of the crank shaft.

    HOW DOES A STEAM ENGINE WORK

    Steam locomotives usually have 2 steam engines mounted on the right and left of the locomotive, the rotational motion produced by the two steam engines is directly used to turn the locomotive wheels so that they are able to pull the entire train series (see picture below).

  • Impact Of Social Mobility: Positive And Negative

    Impact Of Social Mobility: Positive And Negative

    There are many impacts caused by the existence of social mobility. What are the impacts of social mobility and how to respond to these positive or negative impacts? let’s learn together here.

    In the midst of running a social life, surely you have heard the term social mobility. Social mobility in people’s lives does have many contexts and anyone may experience social mobility . In fact, many have experienced social impacts, both the perpetrators and the people around them.

    The impact of social mobility in the midst of people’s lives can be felt. Moreover, this social phenomenon seems to be very close to us and related to people’s lives. But not many understand that he has a high social impact.

    Actually, what is the impact of social mobility and how does this social impact affect people’s daily lives? Before discussing what the impact of social mobility is, we will explain several things covering social mobility, starting from the general understanding to the impact itself.

    Understanding Social Mobility in General

    Before discussing the impact of social mobility, you must first understand what social mobility is in general. By understanding the definition of social mobility in general, you will also understand how social mobility impacts, both positive and negative impacts.

    In general, the notion of social mobility is a change in the position of citizens in one social class to another. Social mobility which will have an impact due to social mobility means the movement of individuals, families, or groups through a system of hierarchies or social stratification .

    Social mobility which will later have an impact on social mobility is also referred to as a social movement which is defined as the movement of people or groups from one social stratum to another. The results of the transfer of social status can be higher, lower, or even remain the same.

    In addition, social mobility can also be interpreted as a transfer of status both vertically and horizontally which will then have an impact on social mobility, both positive and negative impacts.

    Social Mobility Channel

    After understanding the meaning of social mobility which will have an impact, you must also understand that there are various channels of social mobility which will then affect or have an impact on social mobility. At least, there are several channels of social mobility within the community.

    The social mobility channel which will later have this impact serves as a means to carry out social mobility. There are many examples of social mobility channels in the community, but we will explain several channels of social mobility which can then have a social impact on society at large.

    1. Education

    One channel of social mobility that will have an impact on social mobility is in the world of education or educational institutions.

    As we know, educational institutions are places where the educational process or teaching and learning process takes place which has the aim of being able to change human behavior or behavior for the better.

    In the channel of social mobility, namely education, it is divided into several types:

    a. formal education

    Formal education in this channel of social mobility will have a considerable social impact on the community. This formal education covers the school level from elementary or elementary school to university. This educational social mobility channel is systematic, regular, tiered, and has clear requirements.

    Formal education is further divided into several parts, namely general education, special education, vocational education, profession, to religion. This educational institution was founded by the government and the private sector which has a large social impact on community life.

    b. Non-formal education

    This non-formal education also has a social impact, although it is not as big as formal education. Non-formal education is held for the benefit of citizens who need educational services as a complement to formal education.

    Examples of non-formal education are place for courses, study groups, training centers, taklim assemblies, centers for learning activities, and many more.

    The results or values ​​that can be obtained from non-formal education are equivalent to the results or values ​​in formal education, as long as the non-formal education center has received equivalence from a special institution or has referred to national education standards.

    c. Informal education

    In contrast to formal and non-formal education, informal education is usually in the form of family education activities which are usually referred to as human first education because of the role of the family in it. Even so, informal education also has a significant impact on social mobility.

    2. Political Organization

    The second channel of social mobility that also has an impact is political organization. Political organizations are engaged and have an interest in the political process and state science. The impact of this mobility from this political organization is important in shaping a social order that plays a role in determining the fate of the nation.

    Channels of social mobility that have an impact on social mobility, namely political organizations, are divided into several types.

    a. Advocacy group

    An advocacy group is an association that aims to influence political decisions and convince public officials to act in accordance with the voices and interests of the group’s members so that the impact can be felt by the wider community.

    b. Think tank or think tank

    This type of political organization also has an impact because it is tasked with conducting research funded by clients, both government and commercial parties that are useful for the interests of political, social, technological, and weapons members that have a very social impact on a particular group.

    c. Political parties

    This political organization has quite a big impact because they will carry out a certain ideology and the organization is formed with a specific purpose. The purpose of this organization is to gain political power constitutionally so that their various policies can be implemented in a country.

    d. Terrorist group

    The impact of mobility from this organization is also felt by the wider community. This organization has certain ideologies and goals that seek to achieve its goals by means of violence or terror so that the impact of social mobility for the wider community is considered quite dangerous.

    3. Professional Organization

    The channel of social mobility, namely this professional organization, has a great impact on society at large and even individuals. A professional organization is a group of people who have the same goals based on expertise education, including certain skills and vocational.

    This professional organization is a union that is a legal entity and is formed from the same individuals who then develop knowledge, expertise, and so on.

    This professional organization has a social impact for members or the community that is able to improve the skills and abilities of workers or members who are members of it and protect their rights.

    4. Economic Organization

    The next channel of social mobility is economic organization. This economic organization or what is also known as a commercial organization has an impact that is also felt by the wider community. This organization aims to obtain or obtain the maximum profit.

    The main activity of this economic organization has a wide impact because it produces and distributes goods or services which are then offered to the wider community. The goods or services have tariffs that must be paid by consumers. Then, the rate paid becomes the profit or profit of the organization.

    Therefore, organizations that have a fairly large impact on economic mobility are often referred to as profit organizations . These organizations are divided into two types, namely private and government organizations. Of these two types, it is further divided into several types.

    a. Private organizations are divided into Firms (Fa), Limited Liability Companies (CV), Limited Liability Companies (PT), and Cooperatives.

    b. Meanwhile, the government’s economic organizations are divided into State Limited Liability Companies (Persero), Regional Companies, Public State Companies (Perum), and State Service Companies (Perjan).

    In addition to the two types of economic organizations above, there are also other types of economic organizations with social ownership, such as Joint Ventures , Cartels, Foundations, Syndicates, Trusts , Holding Companies , and others.

    Positive Impact of Social Mobility

    The occurrence of social mobility certainly has a positive and negative impact. The following is social mobility that has a positive impact on society at large or individuals.

    1. Encourage one’s progress

    The first positive impact is to encourage one’s progress. This is because social mobility can have an impact on a person’s social status from being low to a higher social status. For example, what many people feel is when Indonesia was colonized and Indonesia became independent as it is today.

    2. Accelerating social change

    The second positive impact is the changes that occur in society and have an impact on the social system. An example of social change that occurs is social change due to social mobility due to globalization. People are becoming more aware of technology, and so on.

  • Social Action: Definition, Types And Examples

    Social Action: Definition, Types And Examples

    Have you ever felt angry or sad over the words or actions of those around you? This reaction in sociology is referred to as social action. In socializing or interacting with people around, two things will appear. Come on, understand the meaning and examples of social action and its types.

    The first is social interaction, and from here comes social action, for example, as mentioned earlier. When someone communicates with other people (social interaction), there will be actions, responses, and the like from both parties.

    Whatever actions, responses, etc., are included in the social actions that arise as an effect of social interaction. Everyone, without exception then, every day, even every second, is doing social actions. Then, what exactly is meant by this social action?

    Definition of Social Action

    Social action, in general, is an action that is influenced and affects other people during social interactions. At the same time, social interaction is a relationship between two or more individuals who influence each other.

    This social interaction’s influence is referred to as the social action earlier. So when there is a social action, the background for the emergence of this action is because there is interaction. With interaction, social action will occur.

    In simple terms, social action can be interpreted as a response or reaction visible to the naked eye after social interaction. The forms then vary so that the types of social action are also very diverse, which will be explained below.

    An example is when there is communication between two people, this communication occurs as an effort to exchange information. After the data is conveyed by one of them, the listener will react.

    Whether it’s happy, surprised, amazed, angry, and so on, it is a form of emotional, social action. Then when the listeners of this information decide to cry, yell, and laugh out loud, it also includes social actions that the perpetrators physically carry out.

    Social actions taken then need to be thought out carefully and wisely because this action will lead to other social actions, which can lead to good or even new problems.

    An example is when someone scolds someone because of that person’s social actions. If the person being scolded does not accept it, they will take social actions to get angry at the first party, gossip, slander behind their backs, and so on.

    So, social action is shaped like a cycle. When you do good actions, the actions of those around you are also good. Vice versa. So in sociology, it is discussed in depth how to interact socially well to minimize social actions with negative effects.

    Understanding According to Experts

    Several experts then explained the definition of social action. These experts then expressed their opinion. In sociology, two experts define social action and are widely known worldwide. That is:

    A. Max Weber

    The first expert to define social action was Max Weber, a figure in sociology. According to Weber, the notion of social action is an action based on social facts that have a major influence on social life, where the social system in this influence is created from the relationship of individuals in their groups.

    B. Ritzer

    Ritzer conveyed the second opinion; according to him, the notion of social action is a repetitive behavior carried out intentionally due to passively influencing situations with similar goals in certain conditions.

    Through the definitions presented by the two experts, it can be concluded. That social action is a repetitive action or behavior carried out intentionally due to the influence of certain situations.

    Situations in social interaction will shape the social actions of all individuals in the relationship. A tense situation will create fear and force the mind to look for ideas as a solution.

    The solution obtained is then immediately applied, and this is also included in social action. In practice, no individual does not perform social action. Even getting up early because you want to go to school or work every day is included in it.

    Types of Social Action

    As explained earlier, the types of social action are as diverse as the forms of social action itself. When viewed from the aspect of things that encourage social action. So social action is divided into 4 (four) types, namely:

    1. Instrumental Rational Action

    The first type is instrumental rational action; as the name implies, this social action is rational. So when someone takes an action, it will be adjusted to the final goal to be achieved.

    A person will not take action without a clear purpose; then, his nature becomes rational and logical. Actions with a clear purpose lead to a clear way as well.

    For example, the social action of a high school student studying hard all night. The goal is to be better prepared for the exam the next day. So learning becomes a social act, and the goal is to be ready for exams.

    2. Value Oriented Action

    The second type is value-oriented social action, which is carried out by considering the values ​​that exist in society. So this action adapts to what is considered good by the wider community.

    The scope of values ​​starts from ethical values, aesthetics (beauty), religion, and other values ​​that exist in society. Value-oriented social action focuses on the benefits and pros and cons of the action in the eyes of society, which overrides the goal.

    An example of this type of social action is when children stop playing football because the call to prayer for the midday prayer has sounded. So they decided to stop playing and pray first, then continue the game.

    3. Affective Action

    The third type is affective action, namely social action that is carried out based on the feelings or emotions felt by an individual. So that this social action is unacceptable, considered illogical, or irrational.

    It is said so because this social action is carried out by prioritizing feelings or emotions so that this action does not involve the mind, which also makes the action unacceptable.

    An example is when a teacher scolds a student in class for being caught cheating, then this student cries. Crying here is a form of affective action because it relies on emotions or feelings.

    Namely the feeling of fear of being scolded and the feeling of worrying about getting a bad grade. Whereas logically, students who cheat should immediately apologize and take responsibility for their actions. Not by crying.

    4. Traditional Action

    The last is traditional action, which is a type of social action carried out because it has become a habit or an action based on a habit and is ingrained.

    Then it relates to all forms of culture or customs so that all social actions of this type are based on the culture applied by the community. This action is hereditary, so it has been happening for a while.

    An example is any action that is done because of custom, such as the Ngaben ceremony for the people in Bali, the Ngebali ceremony in Lampung, the Batu Bakar Party event in Papua, and so on.

    All actions that are carried out based on customs then enter into traditional social actions. This action will continue to be carried out by the community as long as it is inherited or taught to children and grandchildren.

    Examples of Social Action

    It is also possible to know examples of social action to make it easier to understand social action. The form of social action will then be following the types previously stated. The following details an example of social action:

    A. Instrumental Social Action

    In instrumental social action, namely social action based on clear goals. So there are several examples of social action in everyday life related to this type, including:

    1. Ani decided to go to bed early to wake up for the tahajjud prayer at 3 am. (Going to bed early is an act, while the goal is to wake up at 3 am – wake up early for prayer).
    2. Mother sweeps the floor twice a day to keep the house clean. (Sweeping is a social act that aims to keep the house clean.)
    3. Ika eats quickly because she doesn’t want to be late for school. (Eating quickly is a social act, and the goal is to get to school on time.)
    4. Value Oriented Social Action

    B. Value Oriented Social Action

    Social action that is oriented or paying attention to societal values is a value-oriented social action. Examples of social actions include:

    1. Ahmad stopped playing football because it was time for the Asr prayer. (Quitting football for prayer is a social act, its basis is a religious value – prayer times).
    2. We will eat and drink with our right hand at home and public events such as wedding receptions because it is considered better. (Eating and drinking with the right hand is a social act, the basis of which is an ethical value in society – politeness).
    3. A soldier will give his soul and body to the nation and state. (willing to give up body and soul is a social act; the basis is the value of patriotism).
    4. Andi gave up his seat on the city bus to a pregnant woman who happened to be standing. (Giving up a seat is a social act; its basis is an ethical value).

    C. Affective Social Action

    Examples of effective social actions carried out based on feelings and emotions felt are as follows:

    1. Supporters of soccer team A immediately roared with joy in the stadium when their flagship team scored a goal in the opponent’s goal.
    2. Ani cried at the funeral because her mother had just died.
    3. Ika was annoyed on the bus because two young men always teased her along the way even though they didn’t know her.

    D. Traditional Social Action

    Social action based on custom or culture is called traditional social action. Here are some examples of social actions:

    1. Following the Ngaben ceremony for the people in Bali.
    2. Following the Ngababali ceremony in Lampung.
    3. Participate in the Burning Stone Festival in Papua.

    Social action is something that everyone in the community group will always do. This action is a form of overflowing feelings, necessities of life, and so on. So that it will always be there and interesting to understand or study because it can help wiser in acting in the community.

  • The Function of Charcoal in Water Purification

    The Function of Charcoal in Water Purification

    We often hear the question of what is the function of charcoal in water purification. So is it true that charcoal can actually purify water? Let’s see the  following Sinaumedia review  !

    What is Charcoal?

    Charcoal itself is   a black residue which contains impure carbon compounds. Charcoal can be obtained by removing the water content and volatile compounds/components  from  plants and animal bones through the combustion process.

    The form of charcoal is almost like coal consisting of 85% to 98% carbon, the rest is in the form of ash and  other chemical compounds  . There are several basic ingredients for making charcoal such as wood, bones, coconut shells, rice husks and so on.

    The Function of Charcoal in Water Purification

    If you have studied science, you must have done water purification techniques using sand, gravel and stones, right? Can the water you filter be perfectly clear? Of course you can’t! Then why is that? The reason is because the material you use does not contain activated carbon compounds.

    As we know, charcoal contains activated carbon which is able to bind impurities through the absorption or  absorption process . That is, when there is a substance or material that passes through the activated carbon and interacts, the material contained in it will also be absorbed. Therefore, charcoal with activated carbon is able to purify polluted water and at the same time eliminate odors and tastes in the water.

    The use of charcoal in the water purification process is an example of the adsorption properties of colloids, namely the ability to absorb colloidal dispersed particles in water. Dirty water will usually have a lot of colloids that need to be separated using adsorbents such as charcoal, activated carbon and zeolites.

    The way this separation works is by binding the dirt that has accumulated in the water so that the water can be clean and fit for consumption. In addition, activated carbon can also bind to the remnants  of the cleaning agents  used, such as  fluorine  and  chlorine .

    Conclusion

    Purification of dirty water to be clean can indeed use charcoal or activated carbon. You can use charcoal from coconut shells, wood, bones, rice husks and so on.

    The real use in our daily life is in the process of refilling gallons of water. The gallon water refill machine has a purification section with the help of activated charcoal to produce water that is safe for consumption.

  • Understanding Aquades and its functions

    Understanding Aquades and its functions

     This distilled water is something that is commonly found, many people have used this water. Especially in the laboratory. So what is aquadest?, aquadest or some also call it aquadest water is a type of water where this water is produced through a distillation process.

    Then what is the function of aquadest? The distillation process here is a process where the goal is to produce water with very good quality, which later on so that the results of the water can be equalized with mineral water. What kind of mineral water is meant?, namely water in which has a lot of good content.

    Examples such as salt, sulfur, and in the form of gases dissolved in water. Aquatic water is a type of water whose content is able to be equal to mineral water. However, this water can only be obtained by one distillation process. Did not achieve two or more processes.

    Although this water can only be obtained with one distillation process, but still the content contained can exceed the content contained in mineral water. So, mineral water is far superior to distilled water. This does not reduce the use of distilled water.

    A. Definition of Aquades

    Aquadest water is water from the distillation process or can also be called distilled water, which is a process of boiling water which will produce water vapor. This process aims to remove the minerals present in the water. From this boiling process the steam will then be re-solidified in a different container.

    So, after distillation, only H2O is contained in the water, in the absence of other elements. Even though it contains only H2O, this water can still be consumed. Here are some explanations of the advantages and disadvantages of the distillation process:

    The advantages of aquadest water

    Aquadified water certainly has many advantages in its use. Here are the various advantages of aquadest:

    1. From several research studies, that this water can be consumed to help prevent  arthritis . Why is that?, This is because distilled water is believed to be able to get rid of mineral deposits contained in human joints.
    2. Distilled water is also believed to be free from various  microscopic toxins . Examples  are bacteriaviruses , and various  other microorganisms  found in a faucet or tub and can be harmful to the health of the body.
    3. Distilled water is also free from various other chemical mixtures. Such as  chlorinefluoride , and other mixed materials that are likely to be found in ordinary bottled water, or bathtubs in general.
    4. Distilled water is even believed to be an alternative for preventing gallstones. This water will remove the minerals contained in the cells of the human body. So that the risk of gallstone disease can be avoided.
    5. Distilled water also does not have the various ingredients found in tap or bottled water in general. Why is that?, because this water has gone through the distillation process first.

    Lack of Aquatic Water

    Not only does it have various advantages, in fact distilled water also has several disadvantages. Following are the disadvantages of aquadest:

    1. Consuming distilled water in the long term and in excessive amounts can result in poor health. This is because distilled water is able to absorb  very large amounts of carbon dioxide  .
    2. If you continue to consume distilled water, then this results in a rapid loss of electrolytes in the body of the person who consumes it. This is clearly dangerous, isn’t it?
    3. If the body has experienced a deficiency of various electrolytes that are very important, for example, such as  chloridemineralssodium , and others. This can cause irregular heart pressure, this cell also results in blood pressure fluctuations.

    B. Aquatic Functions and Its Various Uses

    Generally, some people consume aquadest as an alternative to absorb various toxic substances in the body, then dispose of them. Even so, there are also those who use this water in various other areas of life that are far more important.

    Because actually consuming distilled water is not always profitable. Another use of this water can be in the  laboratory space . Namely as a mixture of chemical solution substances  . Here are some explanations regarding the use of aquadest water:

    1. Aquatic Function in the Laboratory

    The function of distilled water in the laboratory is as a mixture of chemical substances, when conducting research. In addition, distilled water is also used to clean  laboratory equipment  before or after use. After this, use distilled water as an alternative to assist in research.

    2. Function of Aquades in Steel Processing

    Besides being used in the laboratory, aquadest can also be used in steel processing. What kind of processing is meant?, that is, it is utilized in the process of cutting steel and cooling the engine. It is known to be very effective in inhibiting the presence of scale and moss.

    3. Aquatic Function in Chemistry

    chemical lab

    In the field of chemistry, aquadest can clearly be utilized. As already explained, distilled water is used as a mixture or solvent for chemicals, or certain solutions. This water can be used when researching a concentration or compound.

    4. Aquades Function As Battery Water

    It turns out that this very popular distilled water is also popularly used as a substitute for battery water. Do you know how important  it is to use battery water  in motorized vehicles? The answer must be very important. So this shows that distilled water can be another alternative as a substitute for battery water.

    Those are some explanations about the use of aquadest water in everyday life. Is distilled water considered important and useful?, judging from the explanation above and the many benefits that can be obtained from aquadest, then distilled water is considered very important and beneficial.

  • What is Tawaf?

    What is Tawaf?

    One of the acts of worship in Umrah is performing tawaf. What is Tawaf? Tawaf is one of the pillars of Hajj and Umrah, which is circling the Kaaba seven times. The command to perform tawaf is in QS Al-Hajj verse 29.

    Tawaf  itself has several types. Pilgrims of Hajj/Umroh should also know how to perform this Tawaf because there are several types of Tawaf that become one of the pillars in the implementation of Hajj/Umroh so that if the Tawaf is not performed then the Hajj/Umroh will be invalid.

    In addition, the pilgrims /  Umrah  must also know what things are sunnah in the implementation of tawaf so that their worship becomes better. For more details, see the following discussion!

    Definition of Tawaf

    Tawaf is the activity of circumambulating the Kaaba seven times. This activity is one of the acts of worship performed by Muslims during the  Hajj/Umrah pilgrimage  in the Holy Land. That is a brief explanation of what tawaf is.

    Types of Tawaf

    1. Tawaf Qudum

    Tawaf Qudum or also known as Tawaf Dukhul is a Tawaf performed when you arrive in the city of Makkah. So, this tawaf is a welcome tawaf. Every time the Prophet SAW entered the Haram Mosque, he always performed Tawaf Qudum as a substitute for the Tahiyatul Masjid prayer.

    This Tawaf is a Sunnah law, so if it is not performed, it will not invalidate the performance of Hajj/Umrah. To perform Tawaf Qudum, you don’t need to run around, just walk normally. Women who are menstruating or postpartum are not allowed to perform this tawaf.

    1. Tawaf Tathawwu

    Tawaf tathawwu is a Tawaf that can be performed at any time. This Tawaf serves as a substitute for the Tahiyatul Masjid prayer when entering the  Haram Mosque.

    1. Tawaf Ifadah

    Tawaf ifadah is Tawaf pilgrimage or Tawaf Rukun. This circumambulation is one of the pillars of Hajj so if it is not performed then the Hajj will be invalid. The performance of this tawaf is prioritized on the 10th of Dhul Hijjah, after throwing the jumrah aqabah and  tahallul  or shaving the hair. In addition, tawaf ifadah should also be performed before the end of the tasyriq days (dates 11, 12, and 13 Dzulhijjah).

    1. Tawaf Wada

    What is Tawaf Wada? Tawaf Wada is a parting Tawaf which is also known as Tawaf Shadar (return Tawaf). It is referred to as the return circumambulation because after that the pilgrims  will  leave Makkah and return to their respective places. The law of this circumambulation is mandatory so if you do not perform this circumambulation then you must pay the dam.

    Procedure for the Implementation of Tawaf

    1. Carry out the conditions of prayer, namely purification, intention, covering the genitals, and so on. But in tawaf we are still allowed to communicate with other people.
    2. The left shoulder should be straight towards the Qiblah and should not look back.
    3. The rotation is counterclockwise and starts from the point of Hajar Aswad
    4. Do a round of seven rounds.

    Sunnah When Performing Tawaf

    In performing Tawaf, there are several sunnahs that can be implemented by Hajj/Umrah pilgrims, among them:

    1. Tawaf should be carried out on foot, except for pilgrims who are weak or sick.
    2. Kissing  Black Stone  every time you cross it. But if they can’t kiss the Black Stone, the Hajj/Umrah pilgrims can also give a signal to kiss the Black Stone. At the peak of the hajj season, many pilgrims try to kiss the Black Stone. This makes it a bit difficult for the congregation to reach the Black Stone.
    3. Run fast on rounds 1-3 and run normally on rounds 4-7.
    4. Performing two rak’at sunnah prayers behind Ibrahim’s maqam after completing tawaf.

    That is the discussion about what tawaf is, its types, implementation procedures, and sunnahs in the implementation of tawaf worship.

    The definition of embargo is a prohibition imposed by the government of a country, to export or import certain goods or products to other countries in the framework of policies related to economics, politics, and other policies.

    Therefore, the term embargo can be concluded as an order given by a country, which aims to limit trade and exchange with certain countries.

    The term embargo is generally used in international politics and commerce. An embargo is declared in the form of a policy by the government in a country against other countries in order to isolate the country concerned.

    This will cause the government of an isolated country to be in a fairly difficult internal situation. This difficult internal situation occurred because of the influence of the embargo which caused the economy of the opposing country to suffer.

    The policy, will also limit all trade with a country or aim to reduce the exchange of certain goods.

    In general, embargoes are used as a political punishment for violations of a policy or agreement.

    In general, embargo policies are enforced to force a country to submit to and comply with countries that prohibit exports and imports.

    In other words, an embargo is a weapon that can paralyze a country’s economy.

    If the embargo is enforced for a long period of time, then of course the people in it will experience the impact of the embargo.

    People’s welfare will also decline and can have an impact on other sectors in a country.

    In addition, embargoes are also treated as a result of unfavorable political and economic relations between nations.

    For example, a military embargo is intended to prevent the exchange of military goods from occurring with a country.

    Indonesia itself had received an embargo from the United States. The US embargo was in the form of a ban on exports and imports of military weapons procurement from 1999 to 2005, due to human rights violations committed by ABRI in East Timor.

    America has often made trade embargo decisions and other economic sanctions because of the mandate from the United Nations.

    An example is after the attacks on September 11 in 2001, the United States imposed an embargo on trading commodities to several countries in the Middle East which were accused of being the cause of the attack.

    The embargo does not only apply to all goods and commodities that are exported or imported from the borders of a country.

    Often times, embargoes only apply to certain goods, such as oil and military equipment.

     

    Purpose of the Embargo

    As previously explained, a country is forced to impose an embargo on another country with the aim of making it difficult for the target country to obtain various kinds of commodities, and especially goods that are the country’s needs.

    The implementation of this embargo policy was triggered by a conflict of interest that occurred between the two conflicting countries, where the country that carried out the embargo hoped that the policy would be able to force other countries to voluntarily sit down together and resolve the issues that were going on between the two.

    The United States, is one of the countries that often implements embargo policies on countries that are considered problematic by them. Both with superpowers and countries globally.

    North Korea, Cuba, to Iran and Indonesia are examples of countries that had been hit by the economic sanctions embargo from the United States.

    Even so, the United States was also affected by this embargo regulation. America is suffering from a shortage as well as an increase in fuel prices, because members of the Organization of the Petroleum Exporting Countries (OPEC) carry out an oil embargo on America.

    Embargoes are carried out by certain countries such as America, because they are considered a tool to influence.

    This embargo is quite often used by several countries that have trade agreements between countries, especially exports and imports.

    Because many countries depend on global trade, embargoes are also considered a powerful tool that can affect a country.

     

    Types of Embargo

    In general, embargoes are divided into two types. Here’s the explanation.

    1. Economic Embargo

    The first type of embargo is an economic embargo. Prohibition or stopping of commodity traffic from one country to another that has interests or is experiencing conflict.

    Including export and import activities between countries, such as trade embargoes on the defense system or defense equipment and oil.

    In short, the economic embargo is the prohibition of all forms of economic activities. Both export and import activities in countries that are currently receiving sanctions from the embargo.

    Considering the need for certain raw materials, this economic embargo will have an impact on shocks for a production company.

    So the production of certain goods, of course, will require raw materials imported from other countries at much more expensive prices and different levels of quality.

    The policy of this embargo, of course, will have a negative impact. Especially if the country concerned has a level of dependence on raw materials that must be imported or commodities from a country that is ready to import.

    This will bring considerable losses to countries experiencing embargo sanctions.

    The policy of the embargo will also have an impact on economic conditions in a country, namely making the affected economy unstable.

    Huge losses and a fairly severe impact of the economic embargo was massive layoffs.

    In addition, the two countries, both those that impose embargoes and are subject to embargo sanctions, can also be involved in a cold war.

    Because of that, many countries have finally implemented negotiations and even involved the WTO and the United Nations in order to be able to implement the steps they feel are the best in implementing the embargo action.

    This is done in the interest of peace between the two countries and the lives of the people in those countries.

    In addition, the embargo policy also has a certain period of time and has previously been adjusted to the decision of the country of the embargo giver.

    However, it must first contain an agreement between the two countries, if the previous embargo policy is to be lifted.

    In order to be able to lift the embargo policy, of course it will not be easy to do.

    In fact, in general, there will be negotiations that are quite tough and will take a long time to be able to lift the embargo policy.

    2. Information Embargo

    The second type of embargo is the cessation of publication or distribution of all news, both news and information within a certain period of time.

    In the Press Freedom Law itself, it has been stated that the prohibition of embargoes is a legal provision that must be obeyed.

    If a violation occurs, the news company will also receive strict sanctions and fines whose punishment will be determined later.

    A simple example of this information embargo is when a company announces the company’s profits in the mass media, then the public relations party of the company will also provide the data and information needed for publicity.

    However, there is some information that will explain that there is an embargo.

    Where previously the company would officially state that it was led by the leader of the company, then the data and all information provided would be prohibited from being published by the media.

     

    Impact of the Embargo

    As we knows, that the main purpose of imposing an embargo is to force the target country so that the country can remain subject to the wishes of the country implementing the embargo.

    This step is one of the weapons that is considered quite powerful to cripple the economy of the country affected by the embargo.

    The unavailability of products and basic needs in a country will certainly make the economy in that country shake.

    The existence of this instability, will have an impact on the decline in the level of welfare in the country.

    Not only the economic downturn, the embargo sanctions can also have an impact on the cold war and disrupt world peace.

     

    How to Overcome the Embargo?

    Considering the impact that can harm many parties, the embargo has become an event that is often difficult to avoid.

    Countries that have been subject to embargo sanctions, will feel some adverse effects.

    However, there are several efforts that can be made by countries that are subject to sanctions to survive the embargo, namely by focusing on surviving by optimizing the resources owned by the country.

    For example, when a country is subject to economic embargo sanctions which then cause imports to that country to be stopped.

    So, the way to overcome this situation is to develop products independently according to the needs of the community.

    However, maybe the quality and quantity of these products will be different, but by taking these steps, at least they are able to cover people’s needs for these products.

    Another effort that can be made by countries that are subject to embargo sanctions is to establish good relations with other countries.

    This needs to be done, so that the country is able to survive even though the country is experiencing an embargo.

     

    Some Examples of Embargo Cases

    For a more complete explanation of this embargo, here are some cases of embargoes that have previously occurred in various countries.

    1. Economic Embargo on Iran by the United States

    America often imposes sanctions embargoes, including economic embargo sanctions on Iran, namely in the form of prohibiting exports of crude oil to Iran and the sanctions embargo, announced by Barack Obama, who serves as President of the United States.

    At that time, Iran also experienced a number of losses such as its potential market for oil exports.

    In fact, when the economic embargo sanctions were applied, oil exports from Iran immediately fell to 1.5 million barrels per day.

    Thus, Iran can only rely on exports to a few countries in Europe and the Middle East.

    Then in 2015, the United States lifted the sanctions embargo on the condition that Iran must be willing to reduce its nuclear weapons production capacity.

    By lifting the sanctions of the economic embargo, the export activities of crude oil in Iran again increased to 1 million bpd and Iran became part of the Comprehensive Plan of Action (JCPOA) as a form of Iran’s commitment to the nuclear weapons control program.

    Then in 2018, America again imposed an embargo on Iran. The embargo sanctions did not only affect the two countries involved, but also had an impact on the global economy.

    2. An arms embargo by the European Union on Guinea

    In 2018 the United Nations passed a resolution to impose an arms embargo on the country in South Sudan. The policy was adopted by the United Nations, as a response to the existence of conflicts and ethnic violence that continues to occur in the country.

    The resolution, proposed by America. Of the 15 members of the UN Security Council, nine countries supported the embargo policy, including Russia, Ethiopia, China, Equatorial Guinea, Kazakhstan and Bolivia, which abstained.

    In addition to implementing an arms embargo, the UN Security Council also passed another resolution in the form of imposing a travel ban and imposing an asset freeze on South Sudan’s deputy defense chief.

    South Sudan’s deputy defense chief is considered one of the main actors responsible for the conflict and ethnic violence in his country.

    3. Embargo on Cuba

    In 2014, the United States also imposed economic sanctions on Cuba and it has cost Cuba 3.9 billion US dollars or approximately more than Rp. 49.9 trillion in the last year in the foreign trade sector.

    The total loss due to the embargo from America for 55 years even reached Rp1, 377 T, as stated by the Cuban government ahead of Cuba’s annual report to the United Nations in 2014.

    The report is submitted by the Cuban side to the United Nations every year to encourage the lifting of the economic embargo on the country.

    Then for decades, Cuba has also received support from many countries, which is then manifested in UN resolutions relating to the urge to lift the embargo.

    In 2013, 188 countries also supported the resolution, but only two countries voted against it, namely America and Israel.

    It is known that America first imposed an economic embargo on Cuba in 1960 and had begun a full embargo in 1961 after Fidel Castro won his victory in the Cuban uprising in 1959.

    According to reports, if Cuba does not get the sanctions of the embargo, Cuba can make a profit of up to 205.8 million US dollars from the sale of rum and cigars.

  • 3 Main Theories of Sociology

    3 Main Theories of Sociology

    Actually, the scope of sociology itself is very broad because it covers almost all fields in people’s lives. Such as economics, education, politics, religion, or culture. And of course all these fields are seen from a sociological perspective.

    The majority of science has its own theory. Like medical science, for example, it must have a theory on how to carry out disease examinations on patients. Likewise, sociology has a theory to explain various things that happen in society.

    Each theory has its own level of certainty. Generally, natural science theories have a higher degree of certainty than social sciences. In social science, theory is more subjective which depends on the point of view of seeing a phenomenon.

    3 Main Theories of Sociology

    In addition, social reality is always changing from time to time, so a social science theory rarely changes. Until there is no other theory that can prove otherwise, a social science theory will not change at all.

    1. Symbolic Interactionism

    Symbolic Interactionism is a combination of the thoughts of George Herbert Mead, Herbert Blumer, and Max Weber. The first theory analyzes society based on the subjective meaning of an individual in social interaction.

    This theory also assumes that individual actions tend to be based on things that are believed, not objectively true. This belief is what is referred to as the product of the represented social construction. The result of this interpretation is then known as the situation.

    Symbolic interactionism is a part of micro-sociological theory because its analysis is based on individual aspects. The concept of this theory also tends to have a tendency to deal with one’s identity.

    2. Conflict

    Conflict theory assumes that differences in the interests of social classes result in conflictual social relations. This theory was initiated by Karl Marx.

    Social inequality is created because of the unequal distribution of wealth so that when the gap gets worse, the potential for conflict to arise is even greater.

    The social class referred to here is the proletariat and the bourgeoisie. The first group is the working class or people who have no control over resources. Meanwhile, the second group controls the resources because they have large capital.

    From the two classes, it is clear that the interests and goals of the two are very different. The proletariat wants wealth to be evenly distributed. While the bourgeoisie actually wants to increase power or maintain the power it already has.

    The friction between these two groups if left unchecked will trigger a revolution. Especially when coupled with class consciousness that makes the proletariat know that they have actually been exploited.

    3. Structural Functionalism

    The last theory was born from Emile Durkheim. He has the imagination that society is an organism consisting of various components, these components influence each other so that they can function continuously.

    Structural functionalism emphasizes that society is composed of structural systems that have their own roles. Therefore, the result of the overall system that runs can create social stability.

    In this theory, social institutions will survive as long as they function properly. If there is a malfunction, then the institution will slowly disappear.

    In addition, there must be good cooperation among social institutions (such as government, religion, economy, education, family, media, etc.) so that the system can be maintained.

     

  • Learn Effectively using the Pomodoro method

    Learn Effectively using the Pomodoro method

    Lack of focus when studying is a problem for every student. Maybe it’s time for you to replace your study technique with the pomodoro technique .

    When studying there are people who find it difficult to focus and are easily distracted by other things. For example, the desire to play mobile phones, watch movies , or talk to other people. 

    However, there are also people who are so focused on studying that they forget time to rest. As a result, the brain will be exhausted and allow the occurrence of burnout due to too long studying. 

    The pomodoro technique can be a solution to the two problems above. 

     

    What is the Pomodoro Technique? 

    The pomodoro technique is a learning technique introduced by Francesco Cirillo

    In Italian, pomodoro means tomato. This name was taken because while developing the pomodoro technique, Francesco used a tomato-shaped timer. 

    The essence of the pomodoro technique is a focused learning technique for a certain period of time, ignoring distractions, and interspersed with rest periods. 

     

    How to Apply the Pomodoro Technique

    Then how to apply the pomodoro technique? Check out the following explanation, yes.

    1. Avoid Things That Can Be Distracted

    The first step is to avoid things that make you lose focus. Usually, what often happens is being distracted by the cellphone. 

    Whether it’s because there is an incoming notification or just a desire to check the cellphone and end up not doing the task. 

    Therefore you can change the cellphone mode to silent. Or turn off the cellphone internet and turn it into airplane mode. 

    Also, choose a quiet room. The goal is that no one else interferes with your focus on studying and doing assignments. 

     

    2. Prepare the task to be done

    The second step is to prepare the tasks to be done. It would be better if you do the task from the highest priority scale. 

    You can make a list of the tasks you have and the deadlines for their collection. Choose and work on the task with the closest submission deadline. 

    This will help you remember to do your assignments and be able to submit them on time. 

     

    3. Set Timer For 25 Minutes

    The third step is to set a timer for 25 minutes.

    As previously explained, the pomodoro technique is a technique of learning and doing work within a certain time. 

    It doesn’t take too long, the important thing is that you can focus on the task you’re doing and make good use of your time

    For example, by giving 25 minutes to do assignments in each session. You can use a cellphone or an alarm clock to set this time. 

     

    4. Focus on Your Tasks

    The fourth step is to do the task with focus. 

    Use the 25 minutes well. Focus on the task you are working on. 

    Try not to glance at your phone or chat with other people. That is why in the first step when you want to apply this pomodoro technique, you are required to avoid things that can break your focus. 

     

    5. Rest for a while

    The timer will sound after 25 minutes. That’s a sign you’re entering time to rest. 

    Take at least 5 minutes to rest before continuing to work on the task for another 25 minutes. 

    You can use this break to drink, eat a snack, go to the toilet, listen to music , or just stretch. 

     

    6. Do Repetition

    When the 5-minute break is over, you can set an alarm for another 25 minutes. 

    After a break, return to focus on unfinished tasks. Repeat the steps above at least 4 times. 

    After the alarm goes off for the fourth time, you can give yourself a longer break. For example 15-30 minutes. The most important thing is that you can get your energy back to do the task again later. 

     

    Closing 

    Those are the steps to apply the pomodoro technique from sinaumedia. This pomodoro technique not only serves to increase focus, but can also increase productivity and avoid burnout due to studying too long. 

  • Atomic Habits: How to Turn Bad Habits into Good Habits

    Atomic Habits: How to Turn Bad Habits into Good Habits

    How to turn bad habits into your good habits today? Have you ever felt that you are just going with the flow of life without ever being the person you want to be?

    It usually happens during the new year, you have so many resolutions that you wonder how to turn bad habits into good ones.

    This is not an easy thing, so the question arises how do you change bad habits into good ones more easily and automatically?

    Based on a book written by James Clear entitled Atomic Habits , here is a review of his book and what lessons we can learn from Atomic Habits.

    This review is quoted from the YouTube channel Escaping Ordinary (BC Marx) in the video entitled How to become 37.78 times better at anything | Atomic Habits summary (by James Clear) uploaded on October 6, 2021.

    Comparison Between Hard Work vs 1% Grow

    “A slight change in your daily habits can guide your life to a very different destination,” ungkap James Clear.

    Often times, we convince ourselves that working hard all day long will lead us to success.

    We even other people see it, then give appreciation to us. But the truth is no, even if you grow even only 1% steps every day, you can achieve success.

    This 1% which is not even visible to the naked eye will make a great impact in life.

    Let’s try a math calculation. If we do something meaningful even only 1% per day. Calculate multiplied by 365 days per year, then the result is:

    This means that 1% better every day gives a percentage of up to 38 times better. While 1% worse every day will give a percentage to 0. This means that it does not achieve anything.

    Daily habits can complicate you in the form of stress and negative thoughts. Or daily habits can make you grow in the form of knowledge, productivity, skills, and healthy relationships.

    Nothing is Instant, Everything Needs a Process

    “Success is the product of daily habits, not once in a lifetime transformations.” – James Clear

    The truth about progress is not what most of us or most people think. In fact, progress to move forward does not always run smoothly without obstacles.

    The line is not straight, it is curved and at that time, James Clear called it “the abyss of despair.”

    You’ve been trying hard, risking everything, but still getting no results. That’s when you stop and go back to bad habits.

    The best, most perfect results you will achieve can only be obtained from a growth process that has many delays, so patience is key.

    Goals vs System

    “Forget about goals, focus on system instead.” – James Clear.

    Goals are the goals you want to achieve, while the system is how you can go through the processes that lead you to the results,

    There are policies, societal stereotypes that suggest several ways to achieve your goals and of course you should focus on those goals, such as:

    1. Regular exercise to achieve body goals
    2. Building a business
    3. Maintain good relationships with family, and spend a lot of time with family.

    However, James Clear countered by changing the stereotype by only leading us to the system, not the goal. The following problems will occur if you only focus on goals.

    “Goals are good for setting a direction, but systems are best for making progress.” – James Clear.

    The problem that occurs when changing habits is not with you, but in the system you apply.

    Atomic Habits means implementing small routines and attitudes to produce positive results . Hard work can achieve more attention than small growth.

    But what really matters is how to make decisions every day and the actions we take.

    “Just as atoms are the building blocks of molecules, atomic habits are the building blocks of remarkable results.” – James Clear

    3 Layers of Behavior Change

    1. The first layer is changing outcomes or results. Results are what you want to achieve.
    2. The second layer is changing the processes you do, such as changing your exercise pattern, developing a reading routine.
    3. The third layer is changing your identity. This includes what you believe, your perception of the world, and how you value yourself and others.

    The goal is not to learn to play an instrument, but how to become a musician. The goal is not how to run to the finish line, but how to become a professional runner.

    So apply these thoughts every day in your mind, then you can turn bad habits into good habits.

  • The Saragosa Treaty | History, Background, Content and Impact

    The Saragosa Treaty | History, Background, Content and Impact

    History of the Saragosa Treaty – The Saragosa Treaty is an agreement between the Portuguese and Spanish which was signed on April 22, 1529. The purpose of the agreement was so that the two parties would not clash over the colonial territory in the Maluku region. The trigger was the arrival of the Spaniards in Maluku, after the Portuguese had previously occupied the area.

    The results of the Saragosa Treaty required Spain to leave the Maluku region. In addition, there was an agreement regarding the Spanish and Portuguese territories. The treaty is so named because it was held in the city of Saragosa, Spain.

    Saragosa Treaty

    The following will share the history of the Saragosa Treaty , including the background of the agreement, the characters involved, the results and contents of the agreement to the consequences and impacts.

    Background of the Saragosa Treaty 

    The history of the Saragosa negotiations was motivated by the conflict between the Spaniards and the Portuguese in the Maluku region. This is because both parties want to monopolize the spice trade in the Maluku region.

    Initially the Portuguese arrived in Maluku in 1512 AD. They were received by the King of Ternate, who at that time was in conflict with the Tidore Kingdom. The king of Ternate asked the Portuguese for help to build a fort. In return, the Portuguese were given the right to a trade monopoly.

    But in 1521 AD, the Spanish expedition arrived in Tidore. The arrival of Spain started the conflict between the Portuguese-Spanish. Both sides accused the other of violating the Tordesillas Agreement, the previous agreement between Portugal and Spain.

    For this reason, a new agreement was then held between Portugal and Spain to resolve the previous dispute, where the agreement was named the Treaty of Zaragoza or the Saragosa Agreement.

    Characters of the Saragosa Covenant

    The Saragosa Agreement involved two parties, namely the Spanish and the Portuguese. From the Spanish side it was represented by Emperor Charles V. While from the Portuguese side it was represented by King John III. The two heads of government signed the dossier of this agreement.

    Time and Place of the Saragosa Treaty

    The Treaty of Saragosa was signed on April 22, 1529. The place where the Saragosa negotiations were held was in the city of Saragosa, Spain. This treaty was signed by the two heads of government, King John III and Emperor Charles V.

    Purpose of the Saragosa Treaty

    The purpose of the Saragosa agreement was that Portuguese and Spanish troops did not compete with each other in fighting over the kingdoms and colonies, so an agreement was made from both parties, Spain and Portugal which had been agreed upon.

    Contents of the Saragosa Treaty

    The contents of the Saragosa Treaty are as follows:

    • Earth is divided into two influences, namely the influence of the Spanish and Portuguese.
    • The Spanish territory stretched from Mexico to the west to the Philippine islands and the Portuguese territory stretched from Brazil to the east to the Maluku islands. The area west of the Saragosa line was under Portuguese control.

    Impact of the Saragosa Treaty

    There were several implications of the Treaty of Saragosa. The main thing is that the Spaniards had to leave the Moluccas. Instead, they concentrate their activities on the Philippines. Meanwhile, Maluku became the Portuguese territory.

    Now that’s the historical reference of the Saragosa Agreement including the background, purpose, time and place, parties and characters involved, content and results and the impact of holding the Saragosa negotiations. Hopefully it can be a historical reference.

  • Who is Rakai Pikatan ?

    Who is Rakai Pikatan ?

    Sri Maharaja Rakai Pikatan Mpu Manuku was the sixth king of the Medang Kingdom of the Central Java period (or commonly called the Ancient Mataram Kingdom ) who ruled around the 840s – 856 .

    Rakai Pikatan Real name and title 

    Rakai Pikatan is included in the list of kings in the Mantyasih inscription version . His real name according to the Argapura inscription is Mpu Manuku . In the Munduan inscription in 807, it is known that Mpu Manuku served as Rakai Patapan. Then in the Kayumwungan inscription in 824, the position of Rakai Patapan was held by Mpu Palar. Maybe at that time Mpu Manuku had moved to Rakai Pikatan.

    However, in the 850 Water Bone inscription, Mpu Manuku again holds the title Rakai Patapan. Meanwhile, according to the Gondosuli inscription, Mpu Palar had died before 832 . May the Patapan area again become the responsibility of Mpu Manuku, even though at that time he was already a maharaja . This tradition is true in the history of the Medang Kingdom where a king also includes his old title as regional head, for example Maharaja Rakai Watukura Dyah Balitung .

    According to the Wantil inscription, Mpu Manuku built a new capital city in the village of Mamrati so that he was nicknamed Rakai Mamrati. The new palace was named Mamratipura, as a replacement for the old capital city, Mataram .

    The Wantil inscription also states that Rakai Mamrati abdicated and became a brahmin with the title Sang Jatiningrat in 856 .

    Marriage with Pramodawardhani

    The Wantil inscription also mentions the marriage of Sang Jatiningrat alias Rakai Pikatan Mpu Manuku to a daughter of another religion. Historians agree that the princess was Pramodawardhani of the Sailendra dynasty, who was Mahayana Buddhist , while Mpu Manuku himself embraced the Hindu Shiva religion .

    Pramodawardhani is the daughter of Samaratungga whose name is recorded in the Kayumwungan inscription in 824 . At that time, the one who served as Rakai Patapan was Mpu Palar, while Mpu Manuku’s name was not mentioned at all. Maybe at that time Pramodawardhani was not yet the wife of Mpu Manuku.

    Historian De Casparis considers Rakai Patapan Mpu Palar the same as Maharaja Rakai Garung and is the father of Mpu Manuku. Both of them were members of the Sanjaya dynasty who succeeded in establishing a marital relationship with the Sailendra dynasty .

    sanjaya and syailendra dynasty
    sanjaya and syailendra dynasty relief on prambanan temple

    This theory was rejected by Slamet Muljana because according to the Gondosuli inscription, Mpu Palar was an immigrant from the island of Sumatra and all of his children were girls. After all, Mpu Manuku had already served as Rakai Patapan before Mpu Palar. The possibility that Mpu Manuku is Mpu Palar’s son is very small.

    Meanwhile, Mpu Manuku had served as Rakai Patapan in 807 , while Pramodawardhani was still a girl in 824 . This shows that the age difference between the two is quite far. Perhaps, Rakai Pikatan Mpu Manuku is the same age as his father-in-law, Samaratungga .

    Pramodawardhani is not the only wife of Rakai Pikatan. Based on the Hadap inscription, it is known that another wife of Rakai Pikatan was named Rakai Watan Mpu Tamer. Presumably at that time the title of mpu was not synonymous with men.

    This concubine named Rakai Watan Mpu Tamer is the grandmother of Dyah Balitung’s wife , the king who issued the Mantyasih inscription ( 907 ).

    War Against Balaputradewa

    Balaputradewa son of Samaragrawira was the king of the Srivijaya Kingdom . The popular theory pioneered by the historian Krom states that Samaragrawira is identical with Samaratungga so that automatically Balaputradewa is Pramodawardhani’s brother .

    In the Wantil inscription it is stated that Sang Jatiningrat alias Rakai Pikatan fought against an enemy who built a defense in the form of a pile of stones on a hill. The enemy was defeated by Dyah Lokapala, the son of Jatiningrat. In the inscription there is the term Walaputra, which is interpreted as Balaputradewa . As a result, the theory emerged that there had been a civil war over the throne after Samaratungga’s death which ended in the defeat of Balaputradewa .

    Slamet Muljana rejected the notion that Samaragrawira was identical with Samaratungga because according to the Kayumwungan inscription, Samaratungga only had one child named Pramodawardhani . According to him, Samaragrawira is more accurately called the father of Samaratungga . Thus, Balaputradewa was the uncle of Pramodawardhani .

    Popular theory assumes Balaputradewa built a fort from heaps of stone on the hill of Ratu Baka in the war against Rakai Pikatan and Pramodawardhani . However, according to the historian Buchari, on Ratu Baka hill there is no inscription in the name of Balaputradewa , but in the name of Rakai Walaing Mpu Kumbhayoni. Perhaps this figure who rebelled against the government of Rakai Pikatan because he also claimed to be a descendant of the original founder of the kingdom, namely Sanjaya .

    Meanwhile, the term Walaputra in the Wantil inscription means “youngest son”. So, this term is not another name for Balaputradewa , but a nickname for Dyah Lokapala , the hero who managed to defeat Rakai Walaing, his father’s enemy.

    Thus, the popular theory that there has been a civil war between Rakai Pikatan and his brother-in-law, Balaputradewa, may be wrong. May Balaputradewa leave the island of Java not because he lost the war, but because from the start he had no right to the throne of the Medang Kingdom , considering that he was not the son of Samaratungga but his younger brother.

    The Sailendra dynasty under the leadership of Dharanindra succeeded in conquering the Srivijaya Kingdom , even as far as Cambodia . After Dharanindra ‘s death , his power was inherited by Samaragrawira . Perhaps he was not as strong as his father because according to the Po Ngar inscription, Cambodia succeeded in becoming independent from Javanese colonialism in 802 .

    On this basis, after the death of Samaragrawira, the power of the Sailendra dynasty was divided into two, with the aim of making its supervision easier. The power over the island of Java was given to Samaratungga , while the power over the island of Sumatra was given to Balaputradewa .

    Establishment of Prambanan Temple

    Prambanan Temple

    The Wantil Inscription, also known as the Siwagrha Inscription , was issued on November 12, 856 . This inscription not only mentions the establishment of the Mamratipura palace, but also mentions the construction of the sacred Siwagrha building, which translates as Shiva Temple.

    Based on the characteristics described in the inscription, Shiva Temple is identical to one of the main temples in the Prambanan Temple complex . Thus, the main building in the complex was built by Rakai Pikatan, while other smaller temples were probably built during the reign of later kings.

    End of Reign

    The Wantil inscription also mentions that Rakai Pikatan alias Rakai Mamrati abdicated to become a brahmin with the title Sang Jatiningrat in 856 . The throne of the Medang Kingdom was then held by his youngest son, namely Dyah Lokapala alias Rakai Kayuwangi .

    The appointment of the youngest son as maharaja is presumably based on the merit of defeating the rebel Rakai Walaing Mpu Kumbhayoni. This caused dissatisfaction because the Munggu Antan inscription later appeared in the name of Maharaja Rakai Gurunwangi. This name is not included in the list of kings of the Mantyasih inscription , so it can be estimated that at the end of the reign of Rakai Kayuwangi there had been a royal split.

    The names of Rakai Gurunwangi Dyah Saladu and Dyah Ranu are found in the Plaosan inscription after Rakai Pikatan. Maybe they are Rakai Pikatan’s children. Or maybe the relationship between Dyah Ranu and Dyah Saladu is husband and wife.

    In 807 Mpu Manuku had become an official, namely as Rakai Patapan. He abdicated to become a brahmin in 856 . Maybe at that time he was over 70 years old. After his death, Sang Jatiningrat was buried or didharmakan in the village of Pastika.

     

  • The History of Prambanan Temple and Its Origin & Story

    The History of Prambanan Temple and Its Origin & Story

    History of Prambanan Temple – Prambanan Temple is a Hindu-style temple complex in Sleman, Yogyakarta. This temple is also known as Roro Jonggrang Temple. Prambanan Temple is the largest Hindu temple complex in Indonesia. The history of this temple was first built in the 9th century AD during the Mataram or Medang Kingdom.

    According to the Siwagrha inscription, the original name of this temple is Siwagrha Temple, which in Sanskrit means Shiva’s House. This temple was built as an offering to the Trimurti, the three primary Hindu gods, Brahma, Vishnu, and Shiva. But indeed, Lord Shiva is preferred in this temple.

    Prambanan Temple is located in Prambanan District, Sleman Regency, Yogyakarta and Prambanan District, Klaten Regency, Central Java. This temple is located between 2 sub-districts from 2 different provinces. This means that this temple is situated on the border of Central Java and Yogyakarta provinces. Click here to see the Prambanan temple on the maps.

    Prambanan Temple is a UNESCO World Heritage Site. This temple is claimed to be the largest Hindu temple in Indonesia and one of the most beautiful temples in Southeast Asia. As a cultural heritage, this temple is one of the tourist attractions visited by local and foreign tourists every year.

    History of Prambanan Temple

    The following will explain in detail the history of Prambanan Temple, starting from the origin and background of the temple, the development process, the legend that developed in the community, and the rediscovery and restoration of the damaged temple building.

    The Origin of Prambanan Temple

    The history of this Prambanan temple began when the archipelago was still in the era of the Hindu-Buddhist Kingdom. Rakai Pikatan initiated the construction of this temple. He tried to build a magnificent Hindu-style temple to match the Buddhist-style Borobudur Temple that had been built previously.

    The construction of the Prambanan temple is also thought to be aimed at marking the return of the Sanjaya family to power in Java. Indeed, there was a rivalry between the Sanjaya dynasty, who were Hindus, and the Buddhist Sailenda dynasty regarding their power in Java.

    The temple’s construction became a transition from a Buddhist to a Hindu style in the Mataram or Medang Kingdom. Prambanan Temple was also built to glorify Lord Shiva. The original name of this building in Sanskrit is Siwagrha Temple or Siwalaya Temple.

    Prambanan Temple Construction Process

    The temple building was first built around 850 AD by Rakai Pikatan. Then successive kings, such as King Lokapala and King Balitung Mah Sambu, continued the development process. The building method is also accompanied by changes in the water system and the areas around the temple so that the temple is more awake.

    The temple complex was built periodically and continued by kings such as King Daksa and King Tulodong. Hundreds of additional temples were also built around the main temple as a companion temple.

    After that, a very magnificent temple building was formed. The splendor of the Prambanan temple also received wide acceptance from the people of that era. This temple is dedicated to Trimurti, the three primary Hindu gods: Brahma as the creator god, Vishnu as the preserver god, and Shiva as the destroyer god.

    Inside the Shiva temple as main temple, there is a Shiva statue in the garbhagriha or main room. Archaeologists believe that the statue is a statue of the embodiment of King Balitung.

    The splendor of this temple makes Prambanan the great temple of the Mataram Kingdom. Prambanan Temple is a meeting place for rituals and important royal ceremonies. Also, read The History of Borobudur Temple and Its Origin Story.

    The Legend of Prambanan Temple 

    Prambanan Temple was abandoned around 930 AD. This is most likely caused by the violent eruption of Mount Merapi in the north of the Prambanan temple. The capital of the Mataram kingdom was moved to East Java by Mpu Sindok, who later founded the Isyana dynasty.

    Another possible cause for the transfer of the capital is a war or power struggle. As a result, the Prambanan temple needed to be addressed. The temple building began to crumble and collapse. The Prambanan temple became increasingly damaged after an earthquake in the 16th century.

    After the split of the Mataram Sultanate in 1755 AD, the ruins of this temple became the boundary between the Yogyakarta Sultanate and the Surakarta Sunanate. At that time, many residents knew about the existence of this temple but needed to learn its history and origin.

    At that time, myths and fairy tales were developed about the origin of the temple’s existence. The fairy tale tells the story of thousands of temples built in one night with the help of spirits at the request of Rara Jonggrang’s daughter, but then the princess was cursed to become a statue for cheating.

    The story became so famous that the temple is known as Roro Jonggrang Temple. Even today, the story of the temple’s construction in 1 night is still widely told as part of the legend of the community.

    Discovery and Restoration of Prambanan Temple

    CA later discovered Prambanan Temple. Lons from the Netherlands in 1733. This temple also attracted the attention of many circles during the British occupation of Java. Governor General Sir Thomas Stamford Raffles then ordered further investigation of the ruins of this temple.

    Then around 1855, a massive demolition was carried out to restore the temple building. Even so, residents took many statues and temple stones carelessly. The severe restoration of the Prambanan temple only began in the 1930s.

    Dutch archaeologists carried out the temple’s renovation and then continued with native Indonesians. Restoration efforts continue to be carried out even today. The restoration of the Shiva temple, the main temple of the complex, was completed in 1953 and inaugurated by President Soekarno.

    In 1991, Prambanan Temple was officially included in the World Heritage Site protected by UNESCO. Some parts of the temple continue to be maintained and restored, especially after the Yogyakarta earthquake 2006, which damaged several statues and temple buildings.

    So that’s a brief explanation of the history of the Prambanan temple and the origin of the Prambanan temple in full. Currently, Prambanan temple is also one of the tourist attractions visited by many local and foreign tourists—so many references to the history of the Prambanan temple this time.

  • Roem Royen Agreement | Background, History, Results, Content & Impact

    Roem Royen Agreement | Background, History, Results, Content & Impact

    The history of the Roem Royen agreement – The Roem Royen agreement is an agreement between Indonesia and the Netherlands which began on April 14, 1949 and was finally signed on May 7, 1949 at the Des Indes Hotel, Jakarta. His name was taken from the two leaders of the delegation, Mohammad Roem and Herman van Roijen.

    This time, information about the history and background of the Roem Royen agreement will be presented along with the contents, impacts and results of the complete negotiations.

    Roem Royen Agreement Background

    The Roem Royen Agreement were initially motivated by an attack from the Netherlands on Indonesia after the proclamation of independence. The Dutch carried out an attack on Yogyakarta and the Dutch Military Aggression II attack.

    This was coupled with the detention of Indonesian leaders which began to invite criticism from the international community, especially from the United States and the United Nations Council.

    Pressure from abroad which then made the need for negotiations between Indonesia and the Netherlands. Therefore, the Roem Royen negotiations were carried out which became the way to the Round Table Conference (KMB) to be held in The Hague, Netherlands.

    The date of the Roem Royen agreement was from April 14 to May 7, 1948 and took place in Jakarta.

    The Roem Royen Negotiations

    The Roem Royen Agreement began on April 14, 1948. In the Roem Royen agreement, the Indonesian side was represented by Mohammad Roem, several members such as Ali Sastro Amijoyo, Dr. Leimena, Ir. Juanda, Prof. Supomo, and Latuharhary. Meanwhile, the Dutch were represented by Dr. J. Herman van Royen with members such as Blom, Jacob, dr. Van, dr. Gede, Dr. PJ Koets, Van Hoogstratendan and Dr. Gieben.

    Meanwhile, the mediator is UNCI (United Nations Commission for Indonesia) chaired by Merle Cochran from the United States. Then the Indonesian negotiations were strengthened by the presence of Drs. Moh Hatta and Sri Sultan Hamengkubuwono IX.

    The new negotiations ended on May 7, 1949 at the Hotel Des Indes, Jakarta. This agreement began to be signed and the name of this agreement was decided to be taken from the names of the two leaders of the delegation, namely Mohammad Roem from the Indonesian side and Herman van Royen from the Dutch side.

    Result of the Roem Royen Agreement

    The results of the Roem Royen negotiations include:

    1. The armed forces of the Republic of Indonesia must stop all guerrilla activities
    2. The Government of the Republic of Indonesia will attend the Round Table Conference (KMB)
    3. The return of the government of the Republic of Indonesia to the city of Yogyakarta
    4. The Dutch armed forces will stop all military operations and release all prisoners of war and politics
    5. The Netherlands approved the Republic of Indonesia as part of the United States of Indonesia
    6. Sovereignty will be handed over to Indonesia in full and without conditions
    7. The Netherlands and Indonesia will establish an alliance on a voluntary basis and equal rights
    8. The Netherlands gives all rights, powers and obligations to Indonesia

    Impact of the Roem Royen Agreement

    There are many impacts of this agreement on the situation in Indonesia. The contents of the Roem Royen agreement included the release of political prisoners so that Soekarno and Hatta returned to Yogyakarta after being exiled.

    Yogyakarta is also the temporary capital of Indonesia. There was also the handover of the mandate from Sjafruddin Prawiranegara as president of the PDRI (Emergency Government of the Republic of Indonesia) back to Ir. Sukarno.

    The most striking is the ceasefire between the Netherlands and Indonesia. The Roem Royen negotiations ended with the Round Table Conference (KMB) in The Hague, the Netherlands which resolved the problems between Indonesia and the Netherlands.

    This is the reference information for the Roem Royen negotiations covering the background, objectives, history, results and content as well as the impacts. This incident became one of the historic events in the continuity of the Republic of Indonesia that occurred after the independence era.

  • Bangkok Declaration | Results, Content, History, Figure

    Bangkok Declaration | Results, Content, History, Figure

    The Bangkok Declaration was the initial foundation of cooperation from Southeast Asian countries. The Bangkok Declaration was signed on August 8, 1967 in the city of Bangkok, Thailand. The existence of this declaration is considered as the beginning of the establishment of ASEAN. There are 5 ASEAN countries that have signed the Bangkok Declaration.

    The declaration stated the establishment of an association in the Southeast Asia (ASEAN) region. This association was founded with the consideration that countries in Southeast Asia have a responsibility to strengthen economic and social stability, ensure peace and the pace of national development and ensure security stability from outside interference in all its manifestations.

    The Bangkok Declaration is a basis for an agreement to establish regional cooperation in the economic, social and cultural fields in the Southeast Asian region. In addition, there are 7 points of content of the Bangkok Declaration which is also known as the ASEAN goal .

    Bangkok Declaration

    In the following, we explain about the Bangkok Declaration starting from the time and place of signing, the founding figures as well as the results and contents of the Bangkok Declaration and its impact on Indonesia and Southeast Asian countries.

    Signing of the Bangkok Declaration

    The Bangkok Declaration was signed on August 8, 1967. As the name implies, the Bangkok Declaration was signed in Thailand, precisely in the city of Bangkok.

    This declaration also became the beginning of the establishment of the ASEAN organization, namely the organization of countries in Southeast Asia. No wonder this declaration is also often referred to as the ASEAN Declaration.

    Bangkok Declaration Figure

    There are 5 (five) countries that participated in the Bangkok Declaration represented by 5 representative figures. The five countries participating in the meeting in Bangkok are Indonesia, Malaysia, Singapore, the Philippines and Thailand.

    Indonesia was represented by Adam Malik as Indonesia’s foreign minister at the signing of the Bangkok Declaration. The following are the names of representatives of countries now known as founding figures of ASEAN who also signed the Bangkok Declaration:

    • Adam Malik (Indonesian foreign minister)
    • Tun Abdul Razak (deputy prime minister of Malaysia)
    • S. Rajaratnam (Minister of Foreign Affairs of Singapore)
    • Narciso Ramos (Philippines foreign minister)
    • Thanat Khoman (Thai foreign minister)

    Contents of Bangkok Declaration

    Following are the contents and results of the Bangkok Declaration. The following seven points are also known as the purpose of establishing ASEAN in countries in the Southeast Asian region.

    1. Accelerate growth, social progress and cultural development in the Southeast Asian region.
    2. Maintain peace and stability by upholding the law and relations between countries in Southeast Asia.
    3. Promote active cooperation and mutual assistance in the economic, social, cultural, technological and administrative fields.
    4. Provide mutual assistance in the field of training and research facilities in the fields of education, vocational, technical and administrative.
    5. Cooperate more effectively to achieve greater efficiency in the fields of agriculture, industry and trade development including studies on international commodity trade, improvement of transportation and communication facilities and improving people’s living standards.
    6. Increase the study of problems in Southeast Asia.
    7. Maintain close and fruitful cooperation with other international and regional organizations that share common goals and seek opportunities to promote cooperation with them.

    This declaration also approved the establishment of ASEAN or the Association of South East Asian Nations, which is an association of organizations between countries in the Southeast Asia region.

    At the beginning of the declaration there were 5 members who became the founding countries of ASEAN, namely Indonesia, Malaysia, Singapore, the Philippines and Thailand. After that several other countries joined ASEAN such as Brunei Darussalam (joined in 1984), Vietnam (joined in 1995), Laos & Myanmar (joined in 1997) and also Cambodia (joined in 1999).

    The formation of ASEAN was based on the desire for cooperation, especially in the economic field. ASEAN is a non-political and non-military cooperative organization of Southeast Asian countries. The existence of the ASEAN Declaration in Bangkok is also the beginning of cooperation between Southeast Asian countries.

  • Mutualism Symbiosis Examples and Explanations

    Mutualism Symbiosis Examples and Explanations

    There are 3 kinds of symbiosis in general which is a relationship between living things, including symbiotic mutualism, commensalism and parasitism. In this article, we will specifically share the understanding and examples of mutualism symbiosis in ecosystems.

    Understanding symbiosis mutualism is an interaction between two living things that benefit both parties. This means that in this symbiosis, the two living things involved benefit each other without anyone being harmed.

    The first is the service-resource interaction which includes pollination, cleaning and seed dispersal. While the second is service-service interaction where both interactions contribute. This type is also quite rare and rarely found.

    There is also a symbiotic mutualism which is an obligation. This means that the organisms involved need each other to survive. Examples of mutualism symbiosis can be seen all around us, both in animals, insects, birds, plants, bacteria, fungi and even humans.

    Examples of Symbiosis Mutualism

    Below will be explained 20+ examples of symbiotic mutualism in various terrestrial and marine ecosystems along with the interaction process and a complete explanation.

    Flowers with butterflies

    The interaction between flowers and butterflies is one of the best known examples of symbiotic mutualism. Butterflies suck honey and nectar in flower petals to make food. This process also helps pollinate flowers.

    The profit will be obtained by the butterfly which gets its food in the form of honey and nectar. While flowers also benefit because the pollination process is assisted by butterflies.

    Flowers with bees

    Just like the interaction of flowers and butterflies, another example of symbiotic mutualism is the relationship between flowers and bees. Bees also suck honey and nectar from flower petals which help pollinate the flower.

    Benefits will be obtained by bees who get food in the form of honey and nectar. While flowers also benefit because the pollination process is assisted by bees.

    Flowers with beetles

    One more example of symbiotic mutualism in the form of flower pollination, namely the interaction of flowers with beetles. This example is the same as the relationship between flowers and bees or flowers and butterflies. Beetles will get nectar and help the process of pollination of flowers.

    The benefits will be obtained by the beetles that get food in the form of honey and nectar. While flowers also benefit because the pollination process is assisted by beetles.

    Flies with rafflesia flowers

    Flies and Rafflesia flowers are examples of mutualism symbiosis between animals and plants. The Rafflesia flower is known as a flower with an unpleasant odor and is nicknamed the corpse flower. This is used by flies to perch on the Rafflesia flower in search of food.

    Profits will be obtained by flies that get food for free. Meanwhile, the Rafflesia flower also benefits because it is assisted by the pollination process by flies.

    Zebra with wildebeest

    In the African savanna, many herd animals live including zebras and wildebeests. The two species are known to be very familiar with each other. The two herds also often migrate together. In eating, the two also often divide where the zebra eats long grass and the wildebeest eats short grass.

    In relation to predators, the two are also mutually beneficial to each other. Wildebeest have more sensitive instincts, while zebras have sharper eyesight. If there is a predator, the two will warn each other.

    Starling with buffalo

    The relationship between starlings and buffalo is also another example of mutualism symbiosis. Starlings usually perch on the back of buffalo to look for fleas on their skin. Buffaloes will also feel helped by the starlings that eat the ticks on their skin.

    The advantage will be obtained by the starlings who get food in the form of lice. Meanwhile, buffalo also benefit because the itching caused by fleas is reduced.

    Storks with hippos

    The interaction of the stork and the hippopotamus is also an example of a symbiotic mutualism. The stork will eat the fleas and parasites on the hippo’s back. The hippopotamus certainly benefits from the habits of the crane.

    Profits will be obtained by the cranes who get food. While the hippopotamus also benefits because his body becomes clean and free of fleas.

    Crocodiles with plovers

    The next example of symbiotic mutualism is the interaction of crocodiles and plover birds. Plover birds have a habit of eating dirt or food debris in the mouth and teeth of crocodiles. Crocodiles of course also benefit from this habit.

    Profits will be obtained by plover birds who get food for free. While crocodiles also benefit from being free from oral diseases because their feces are cleaned.

    oxpecker with zebra

    The zebra-oxpecker interaction is also almost identical to the starling and buffalo interaction. The oxpecker usually eats fleas and other insects on the zebra’s body. In addition, the oxpecker will be a signal for the zebra if there is a predator coming.

    Profits will be obtained by oxpecker birds who get food in the form of lice. Meanwhile, zebras also benefit because they feel less itching and are signaled when predators such as tigers or lions are coming.

    Tropical pitcher plant with woolly bats

    The relationship between pitcher plants and woolly bats is an example of a mutually beneficial interaction. Wool bats usually live in comfortable places around pitcher plants which also provide benefits for pitcher plants.

    The advantage will be obtained by woolly bats who will get a comfortable place to live. Meanwhile, semar bags also benefit from obtaining fertilizer derived from bat droppings which are rich in nitrogen.

    Spider crab with algae plant

    The spider crab is a species of crab from Japan that lives in the ocean with the characteristics of having long legs. This species lives in the green areas of marine plants. Usually the algae plants will stay on the spider crab’s back.

    Profits will be obtained by algae plants that get a place to live. While spider crabs also benefit from the presence of algae plants, spider crabs can camouflage with their surroundings so that they are not detected by predators.

    Ant with woodpecker

    Woodpeckers like to make holes in trees to make their nests. While ants are common in trees. Both are mutually beneficial to each other. Ants guard woodpecker eggs in trees, while woodpeckers provide protection for ants.

    The advantage will be obtained by the woodpecker where the eggs are protected by ants. While ants also benefit from getting protection from woodpeckers.

    Aphids with ants

    Aphids are parasites that suck leaf sap. After that the ants will approach to press the back of the tick so that the liquid sap that has been processed in the body of the tick will come out and be eaten by the ants. Ants also help aphids to find food by bringing ticks to trees that are larger and contain a lot of sap.

    The advantage will be obtained by the ants who get food from the liquid sap from the tick. Meanwhile, aphids also benefit from being helped to find food by ants.

    Plants with hornbills

    The interaction of hornbills and plants is also an example of a symbiotic mutualism. Hornbill ants often live in trees. The hornbill ants often get food in the form of pests that grow on the leaves of the trees they live in, usually mango or sugar apple trees.

    The advantage will be obtained by the hornbill ants who get food and make nests in trees. Meanwhile the occupied plants also benefit because the existing pests have been eradicated.

    Beans with rhizobium bacteria

    Legumes and rhizobium bacteria have mutually beneficial interactions. Legumes need nitrogen-containing soil for growth. The presence of rhizobium bacteria in the soil helps legumes to obtain nitrogen.

    Benefits will be obtained by legume plants that obtain nitrogen from rhizobium bacteria. While rhizobium bacteria also benefit from getting food from the roots of legumes.

    Termites with flagellate bacteria

    Termites and flagellates interact and benefit from each other. In the body of termites there are flagellate bacteria that will help digest food when termites eat wood. Flagellates secrete cellulose enzymes which function to make hard wood soft.

    The benefits will be obtained by termites which are helped by the process of digesting their food. While flagellates also benefit because they can live in the intestines of termites.

    Farmers with owls

    Humans who work as farmers also have a symbiotic mutualism interaction with owls. Owls will usually prey on mice that are on farmland. This of course also benefits farmers considering that rats are pests.

    The advantage will be obtained by owls who get their prey in the form of mice. Meanwhile, farmers also benefit because rats, which are pests, are reduced.

    Mushrooms with algae plants

    The next example of symbiotic mutualism is the relationship between fungi and algae plants. The fungus will make the surrounding environment moist so that algae plants can grow and can carry out the process of photosynthesis. Later the fungus also gets a share of the results of photosynthesis.

    The benefits will be obtained by algae plants that can carry out the process of photosynthesis. While fungi also benefit because they get food from photosynthesis.

    Humans with plants

    This is an example of a symbiotic mutualism that we should know and feel every day. Humans and plants need each other. Humans emit carbon dioxide which helps the process of plant photosynthesis. While the oxygen produced by plants will be inhaled by humans.

    The benefits will be obtained by plants that obtain carbon dioxide from humans. While humans also benefit in the form of oxygen produced by the photosynthesis process of plants.

    Humans with small intestine bacteria

    Humans also have a mutualistic symbiotic relationship with small intestinal bacteria. Small intestinal bacteria known as Escherichia ecoli are useful for reducing the growth of bad bacteria and speeding up the process of decay in the large intestine.

    Benefits will be obtained by humans where the growth of bad bacteria is reduced and the decay process is accelerated. While the small intestine bacteria also benefit because they can get food debris from the large intestine.

    This is a reference for examples of mutualism symbiosis that exist in terrestrial and marine ecosystems and involve various living things such as humans, plants, animals, fungi, fleas and bacteria. This is an example of an example of mutualism symbiosis this time.

  • Discussion of the Photosynthesis Process in Plants [+Image]

    Discussion of the Photosynthesis Process in Plants [+Image]

    Since we were in elementary school, of course, we are all familiar with the term photosynthesis. Photosynthesis is the process of making food substances carried out by plants that takes place on the role of the sun. If the sun shines very brightly, then the process of photosynthesis can run perfectly. Because without the sun, photosynthesis could never happen.

    Photosynthesis role in the Carbon Cycle
    Photosynthesis role in the Carbon Cycle

    Definition of Photosynthesis

    Photosynthesis comes from two words, photo which means light and synthesis which means the process of making or processing using nutrients. On earth, there are only a few creatures that can carry out photosynthesis. Among them: plants, algae, and several types of bacteria.

    It can be said that photosynthesis is very important for life on this earth. This is because almost all living things are very dependent on the energy produced from the photosynthesis process in plants , especially in terms of obtaining food sources (glucose).

    see phorosynthesis definition from wikipedia.

    Photosynthesis Function

    After knowing the meaning of photosynthesis, we continue with the function of photosynthesis. There are many functions obtained from photosynthesis. And here are some of the functions obtained from photosynthesis.

    Producing Glucose

    Photosynthesis is carried out by plants to produce glucose. Glucose is also the main raw material that can be used as the manufacture of other food substances, such as fats and proteins in plants. These substances are also a source of food for animals and humans. Therefore, the ability of plants to convert light energy into chemical substances has always been the most important thing in the food chain system.

    Convert Carbon Dioxide to Oxygen

    Photosynthesis also functions to clean the air. Carbon dioxide that cause of global warming  can be reduced due to the photosynthesis process carried out by plants. Because carbon dioxide is the raw material used for photosynthesis. The more photosynthesis occurs, the more carbon dioxide content is reduced in the air.

    Produce Coal

    Photosynthesis carried out by plants also causes plant remains that lived in the past and buried in the ground to turn into coal which is still one of the sources of energy for life on this earth. This is of course very important because coal has so many functions and benefits. Therefore, it is appropriate for us to always maintain and preserve the plants that exist in our environment.


    Main Ingredients Used In Photosynthesis Process

    • Carbon dioxide (CO2)
    • Water
    • Chlorophyll
    • Sunlight

    Photosynthesis Process

    Photosynthetic Process
    Photosynthesis Process

    The process of photosynthesis also has stages, and the following steps are carried out by plants during the photosynthesis process.

    • Photosynthesis begins with carbon dioxide taken from the mouth of the leaf at night. After carbon dioxide is taken, plants will then take water from the soil by using the roots carried by the transportation system in plants. The transport system that carries water is called xylem and
    • If sunlight is available, then plant chlorophyll will directly absorb sunlight as the main energy in making glucose
    • Furthermore, glucose will be directly processed into protein, fat, and other substances. The process of photosynthesis is also very complex.

    2 Stages in Photosynthesis

    In general, the process of photosynthesis that occurs in chloroplasts requires sunlight to be able to make glucose. But there is also a process of photosynthesis that does not require sunlight at all. As a result there are 2 types of reactions caused by the process of photosynthesis. The following are the two reactions.

    The two stages of photosynthesis
    The two stages of photosynthesis : Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2. source : lumenlearning.com

    1. Light dependent Reaction / Photolysis

    The light reaction is a photosynthetic reaction that requires the help of sunlight. In general, this reaction takes place in an open space exposed to direct sunlight. The light reactions also take place in the thylakoid membrane in the chloroplast space. In this reaction, chlorophyll will serve as an absorber of sunlight which is used to convert water molecules into oxygen and hydrogen. The light reaction is also known as photolysis.

    2. Dark Reaction / The Calvin Cycle

    If the light reactions desperately need help from sunlight, then the dark reactions don’t need it at all. But the dark reaction can never happen if the plant does not carry out the light reaction first. If the light reactions take place in the thylakoid membrane, the dark reactions take place in the stroma and chloroplasts.

    The processes that occur in the dark reactions are also very complex, just like those that occur in the light reactions. The purpose of this dark reaction is to convert carbon dioxide into glucose. Therefore, the light reaction is closely related to the dark reaction. Because the dark reaction itself can never occur if the plant does not carry out the light reaction first.


    Factors Affecting the Success of Photosynthesis

    There are several factors that can affect the success of the photosynthesis process. The success or failure of the photosynthesis process is very dependent on the elements that are the basic ingredients in the photosynthesis process. Not only that, the condition is also one of the factors that can influence. And here are some factors that affect the success of the photosynthesis process.

    • Internal Factors

    Internal factors are factors that come from plants that will carry out photosynthesis. Because basically there are many types of plants that live in various conditions. Therefore the photosynthetic reactions that occur will also be very different.

    In addition, heredity is also one of the things that greatly affects the process of photosynthesis. For example, such as albino plant species that absolutely cannot produce chlorophyll. So that the type of albino plant can not carry out the process of photosynthesis. There are also several other influencing factors. Among them: leaf age, completeness of plant organs, number of leaves, and carbohydrate translocation.

    • External Factors

    In addition to the internal factors described above, there are also external factors that also greatly affect the success of the photosynthesis process carried out by plants. And here are some external factors that affect the success of the photosynthesis process.

    • Water Availability

    Water is one of the main ingredients needed in the process of photosynthesis. The availability of water in the soil greatly affects the results that will be obtained from the photosynthesis process. The more water content in the soil, the greater the results that will be obtained from the photosynthesis process. Vice versa, if the water content in the soil is very little, the smaller the results that will be obtained from the photosynthesis process. The process of photosynthesis can also potentially fail.

    • temperature

    Photosynthesis is highly dependent on the performance of enzymes. Enzymes themselves can work optimally at a temperature of 23-30 degrees Celsius. If the available temperature reaches minus 5 degrees Celsius or even exceeds 50 degrees Celsius, the photosynthesis process carried out by plants will not produce maximum results.

    • Content of Carbon Dioxide (CO2)

    In order for plants to carry out photosynthesis, plants really need carbon dioxide. Plants must absorb at least 0.03 percent of the existing amount of carbon dioxide. But that’s just the bare minimum. The more carbon dioxide content absorbed by plants, the better the results obtained by plants from the photosynthesis process itself.

    • Oxygen Content (O2)

    Not only carbon dioxide, plants also need oxygen to be able to carry out photosynthesis. Because oxygen is the energy used by plants during photosynthesis. If the oxygen content around is very low, the results will not be perfect. This is because very little oxygen content can inhibit the respiratory system in plants.

    That’s a brief discussion of the meaning of photosynthesis and a little discussion of the processes that occur during photosynthesis. Hopefully the above explanation can add insight to all of us.

    In addition, we all must try as much as possible to be able to maintain and preserve plants so that plants can carry out photosynthesis perfectly. Because if there were no plants, all of us who live on this earth would never be able to live. Because plants play an important role in life on the entire surface of the earth. May be useful!

  • Get to know the types of surgery that exist in the medical field

    Get to know the types of surgery that exist in the medical field

    For some people, they may have had surgery, both for themselves and those closest to them. Hearing the word type of surgical operation, many of us think that the person who undergoes it must be exposed to a dangerous disease, even though it is not necessarily a very serious disease. There are people who undergo minor surgery so that there is no risk to him. This time sinaumedia will review further types of surgery.

    Definition of surgical operation and its types 

    While surgery itself is a method of treatment carried out by medical personnel / doctors to treat a disease by opening / closing certain body parts according to applicable procedures. Not all diseases can be cured by surgery, so doctors must know very well the symptoms, treatment and appropriate treatment for patients.

    Medical personnel or doctors who perform surgery should also not be careless because it can be bad if something fatal happens. Must have had good experience. There are many kinds / types of this surgical operation, judging from its purpose, level of risk, and technique.

    Types of operations based on their objectives are divided into:

    • Diagnose

    Diagnosing disease is an obligation for a doctor in his work. The operation that is commonly performed for this is a biopsy operation which aims to determine the presence of cancer or tumors in the patient’s body.

    • Prevent

    This action aims to prevent the spread of the disease in the patient’s body. For example, surgery to remove intestinal polyps is done to prevent cancer.

    • Remove

    Surgery that aims to remove a number of tissues in the body because it has spread in several body tissues. For example, surgical removal of the uterus, and breast removal.

    • Restore

    The purpose of this operation is to restore the function of certain body organs to normal again. Like breast reconstruction surgery.

    • palliative

    This type of surgery is only to reduce the pain felt by the patient, usually this action is done in patients with end-stage chronic disease.

     

    Surgical operations based on the level of risk are divided into 2, namely:

    • Minor surgery (minor)

    This type of surgery is a surgical procedure that does not require a long time in the recovery process because there is no need to perform surgery in a dangerous area and usually this type of anesthesia uses local anesthesia. For example, surgery on external tissues when an accident occurs in the hands/feet, extraction of nails, ganglion surgery on the hands.

    • Major surgery (severe)

    Major surgery is an operation that is carried out with greater risk because it has to open wider body tissues so that the recovery time for the patient is usually relatively longer. Examples of major operations such as organ transplant surgery, brain tumor surgery, heart surgery and so on.

    Based on the technique of surgery is divided into:

    • Open surgery

    This surgical operation is better known as conventional surgery, where medical procedures are performed by making incisions in the body using a special knife. For example, heart surgery, where the doctor must cut the patient’s chest and open it so that the heart organs are clearly visible.

    • Laparoscopy

    A type of laparoscopic surgery where the doctor only makes a small incision on the body and then inserts a tool such as a tube into the incision hole to find out the problems that occur in the patient’s body

    Based on the timing of the surgery, surgery is divided into 3, namely:

    • Elective

    Surgical procedures are performed to treat diseases that do not endanger the patient’s life and are only performed at the request of the patient.

    • Emergency

    Surgery performed to save a patient’s life or a patient’s body part due to an accident or injury which caused trauma.

    • Semi elective

    Surgery is performed to prevent the effects of an illness or injury, but does not have to be done immediately, this surgery can be postponed for a while.


    Thus the explanation for the types and definitions of surgical operations, this knowledge is to make the general public understand the importance of surgery on body parts to be carried out for some patients. So, we should not equate that all operations are dangerous.

  • Types of Oxygen Masks

    Types of Oxygen Masks

    An oxygen mask is a medical device that provides a method for transferring respiratory oxygen gas from a storage tank to the lungs. Oxygen masks can cover the nose and mouth  (oral nasal mask ) or the entire face ( full-face mask ). Giving oxygen to the patient by using a mask filled with oxygen with a position covering the patient’s nose and mouth.

    Oxygen masks are generally transparent and have straps so they can be tied tightly around the client’s face. There are various forms of face masks. The difference between a rebreathing and a non-rebreathing mask lies in the presence of a valve that prevents exhaled air from being re-inhaled.

    Types of Oxygen masks:

    • The simple face mask delivers oxygen with an oxygen concentration of 40-60% with a flow rate of 5-8 liters/minute.

    Simple_face_mask

    • Rebreathing masks deliver oxygen with an oxygen concentration of 60-80% at a flow rate of 8-12 liters/minute. Has a pocket that continues to expand both during inspiration and expiration. During inspiration, oxygen enters from the mask through the hole between the mask and the reservoir bag, plus oxygen from the chamber enters the expiration hole in the bag. The inspired air is partially mixed with the exhaled air so that the CO2 concentration is higher than that of a simple face mask.

    • The non-rebreathing mask delivers oxygen with oxygen concentrations up to 80-100% at a flow rate of 10-12 liters/minute. In principle, inspired air does not mix with exhaled air because it has 2 valves, 1 valve opens during inspiration and closes during expiration, and 1 valve whose function is to prevent room air from entering during inspiration and will open during expiration.

    How to use :

    • Explain the procedure to the patient (if conscious)
    • Set a comfortable position on the client (semi-fowler)
    • Connect the oxygen tube to a simple facemask with a humidiflier.
    • Adjust the simple facemask so that it covers the patient’s nose and mouth mulut
    • Wrap the rubber mask around the patient’s head so it doesn’t come off
    • Deliver oxygen as needed.

     

     

  • THE 3 TYPES OF RESEARCH

    THE 3 TYPES OF RESEARCH

    Hello Statisticians, this time Sinaumedia will review about recognizing 3 types of research that you need to know. For those of you who are going through a thesis or research, I hope this article can be an inspiration.

    Although there is often a blur within the boundaries, research in general can be classified into 3 types. The first is exploratory research, explanatory research or confirmatory research , and descriptive research.

    WHAT IS SCOPING OR EXPLORATORY RESEARCH?

    An exploratory research is a type of research that is open, still searching, and does not necessarily have a hypothesis. Researchers’ knowledge about the symptoms to be studied is still very little.

    Scoping research is thus often carried out as the first step for more in-depth research, be it explanatory research or descriptive research. Through this exploratory research, research problems can be formulated more clearly and in more detail, and hypotheses can be developed.

    In general, the definition of exploratory research is an activity in conducting an in-depth analysis of something new, which has never existed before.

    Here are some examples of studies with exploratory research designs:

    • A study of the role of social networking sites as an effective marketing communication channel
    • Investigation of how to improve the quality of customer service in the hospitality sector in Bangkok
    • Assessment of the role of corporate social responsibility on consumer behavior in the Garment industry in Vietnam

    DEFINITION OF EXPLANATORY RESEARCH ( EXPLANATORY OR CONFIRMATORY RESEARCH )

    Explanatory research is a type of research that highlights the relationship between research variables and tests hypotheses that have been formulated previously. Therefore, this has also eaten research hypothesis testing or testing research . Although the description also contains a description, as a relational research the focus lies in explaining the relationship between variables.

    Explanatory Research allows researchers to provide deep insight into a particular subject, which breeds more subjects and provides more opportunities for researchers to learn new things and question new things.

    An in-depth study of a subject creates cycles and, critical thinking/study of a subject creates more questions and those questions lead to more ways for the researcher to learn more things related to that subject.

    Explanatory research is a type of research that is a pillar of other types of researchers. Before starting the research for the next research, we should always do explanatory research first, because without it the research would not be complete and would not be as efficient.

    Explanatory research works to give your survey and research design a better focus and significantly limits unwanted bias information.

    THEN, WHAT ABOUT DESCRIPTIVE RESEARCH? WHAT DOES IT MEAN?

    Descriptive research usually has two objectives. The first is to determine the development of certain physical facilities or the frequency of occurrence of certain aspects of social phenomena. For example, the number of two-wheeled vehicles, four-wheeled vehicles, family planning acceptors, the number of films being screened, and so on.

    The results are listed in the frequency table table. the second is to describe in detail certain social phenomena. For example, social interaction, kinship system, and others. Such research is usually carried out without a rigorously formulated hypothesis. Sometimes using a hypothesis but not for statistical testing

    In essence, descriptive research is used to describe various aspects of phenomena. In its popular format, descriptive research is used to describe the characteristics and/or behavior of a sample population.

    An important characteristic of descriptive research relates to the fact that although descriptive research can use a number of variables, only one variable is needed to conduct descriptive research. The three main objectives of descriptive studies can be described as describing, explaining and validating research findings.

    this type of descriptive research is closely related to observational research, but is not limited to the method of collecting observational data. Case studies and surveys can also be defined as popular data collection methods used with descriptive studies.

  • ELEMENTS OF SCIENTIFIC RESEARCH THAT MUST BE UNDERSTOOD

    ELEMENTS OF SCIENTIFIC RESEARCH THAT MUST BE UNDERSTOOD

    Hello statisticians. Are you working on a script or want to take a script? Now this time sinaumedia will discuss the elements of scientific research. Keep on reading.

    To be able to conduct research well, researchers need to have knowledge of various elements of research . The elements that form the basis of this scientific research are: concepts, prepositions, theories, variables, hypotheses and operational definitions .

    Scientific research is a systematic process of proving the relationship. Therefore, the relationship between the elements of scientific research can also be presented systematically below.

    the relationship between the elements of research
    the relationship between the elements of research

    The schematic above shows the theoretical process of the empirical process of a research; formulation of concepts, positions and theoretical arrangements in a scientific research. Formulation of operational definitions, data collection, formulation and testing of statistical hypotheses is an empirical process.

    It should be remembered that the research process is an ongoing process and begins with the researcher’s deep interest in the relationship to be studied.

    With the interest and ideas, the research process increases in theoretical understanding (which requires an understanding of concepts, theoretical propositions), hypothesis formulation (including an understanding of hypothetical variables, operational definitions and statistical hypotheses), and hypothesis testing.

    ELEMENTS OF SCIENTIFIC RESEARCH

    Below, the statistical consultant’s efforts will describe the elements of this research one by one with examples of their actual use.

    1. CONCEPT

    The concept of research is the most important element of research and is the definition used by researchers to abstractly describe a social phenomenon or natural phenomenon.

    For example, to describe the reproductive capacity of poultry known as the concept of fertility and hatchability. Another example to illustrate population movement is known as the concept of migration and mobility.

    Some of the concepts commonly used in population research and social research include the value of children, contraceptive behavior, labor force, unemployment and so on.

    2. PREPOSITION

    Prepositions are statements about the nature of reality that can be tested for truth. A hypothesis is a proposition formulated for empirical testing. Theorems or laws are also prepositions that have a wider range or scope and have received a lot of empirical support.

    3. THEORY

    Theory is the main means of expressing the systematic relationship between social and natural phenomena to be studied. A theory is a logical sequence of one or more prepositions.

    Is scientific information obtained to increase the abstraction of meanings and relationships in prepositions. Theory is scientific information obtained by increasing the abstraction of meanings and relationships in prepositions. More complex theories are usually logical combinations of several prepositions.

    4. VARIABLE

    Another element commonly known as the element of research is the variable. Variable is a concept that has a variety of values.

    So, the concept of the body is not a variable why and does not contain the meaning of the existence of varying values. Weight or height are variables because they have different values.

    Sex is a variable because it can have a value that is male or female. Age, education, marital status, number of children, home ownership status, money supply are all variables.

    Concepts that do not contain multiple value meanings can usually be turned into variables by focusing on certain aspects of the concept.

    An example is eggs. The concept of eggs can be used as a variable, for example by assessing aspects of egg weight, egg length and width, egg color and so on.

    5. HYPOTHESIS

    As previously discussed, the research objective is to examine the systematic relationship between the variables. This relationship is usually presented in the form of a hypothesis which is an important research element.

    A hypothesis is a tentative conclusion or preposition about the relationship between two or more variables. The hypothesis is always presented in the form of a statement that links explicitly or implicitly a variable with one or more other variables.

    A good hypothesis must meet 2 criteria. First the hypothesis must describe the relationship between the variables. Both hypotheses should provide clues on how to test the relationship. This means that the variables listed must be measurable and the direction of the relationship between these variables must be clear.

    Example of a hypothesis in animal husbandry research: the fertility rate of native chicken eggs is influenced by the quality of feed and the age of the mother.

     

    6. OPERATIONAL DEFINITION

    One element of research that really helps communication between researchers is the operational definition. The operational definition is an indication of how a variable is measured. By reading the operational definition of a study, a researcher will know the measurement of a variable, can know the good or bad of the measurement.

    In the operational definition section, it is usually explained how the research method is carried out. such as the number of samples, how to measure variables, the research process, experimental design, how to analyze statistical data, and so on.

    Well, that’s the article about the elements of research from sinaumedia , I hope this article is useful and enlightening. see you again in the next article. stay tuned.

  • Definition of Capacitor and How it works?

    Definition of Capacitor and How it works?

    Understanding Capacitors, Types, Formulas, Kinds, Types, Functions and Examples: are electronic components that have the ability to store electrons for a certain time or electronic components used to store electric charges.

    Definition of Capacitor

    A capacitor or capacitor by Michael Faraday (1791-1867) is essentially a device that can store energy/electrical charge in an electric field, by accumulating an internal imbalance of electric charge or an electrical component capable of storing an electric charge formed by a surface. (disk or chip) connected which are separated by an insulator.

    Michael Faraday
    Michael Faraday

    When a capacitor is connected to a voltage source, the disk or plate is filled with electrons. When electrons separate from one plate to another, the electron charge will exist between the two plates. This charge is caused by a positive charge on the plate that loses electrons and a negative charge on the plate that gains electrons.

    Capacitors are electronic components that have the ability to store electrons for a certain time or electronic components that are used to store electric charges consisting of two conductors and are separated by an insulating material (dielectric material) each conductor is called a chip.

    Like resistors, capacitors are one of the passive components that are widely used in making electronic circuits. Capacitors differ from accumulators in that they store electric charge, especially when there is no chemical change in the capacitor material. Another definition of a capacitor is an electronic component that can store and release an electric charge. Capacitors or often called capacitors are electrical components that are made in such a way that they are able to store an electric charge.

    The principle of a capacitor in general is the same as a resistor which is also included in the passive component group, namely the type of component that works without the need for bias current. Capacitors consist of two conductors (metal plates) separated by an insulating material (insulator). This insulating insulator is often referred to as a dielectric material.

    The dielectric substance used to block the two transmitters of the component can be used to distinguish the type of capacitor. Some definitions of capacitors that use dielectric materials include paper, mica, liquid plastic and others.

    If both ends of the metal plate are given an electric voltage, then positive charges will collect on one of the metal legs (electrodes) and at the same time negative charges will accumulate on the other metal end. Positive charges cannot flow towards the negative end of the pole and conversely negative charges cannot go to the positive end of the pole, because they are separated by a non-conductive dielectric material.

    This electric charge is “stored” as long as there is no conduction at the ends of the legs. The ability to store electric charge in a capacitor is called capacitance or capacity. Capacitance is defined as the ability of a capacitor to accommodate electron charges. Coulombs in the 18th century calculated that 1 coulomb = 6.25 x 1018 electrons.

    Then Michael Faraday postulated that a capacitor will have a capacitance of 1 farad if with a voltage of 1 volt it can carry a charge of 1 coulomb of electrons. With the formula it can be written: Q = CV Where: Q = electron charge in C (coulombs) C = capacitance value in F (farads) V = voltage in V (volts) In the practice of making capacitors,

    The capacitance is calculated by knowing the area of ​​the metal plate (A), the distance (t) between the two metal plates (dielectric thickness) and the dielectric constant (k) of the material. The formula can be written as follows: C = (8.85 x 10-12) (k A/t) The following is a table of examples of the constant (k) of some simplified dielectric materials Vacuum air k = 1 Aluminum oxide k = 8 Ceramics k = 100 – 1000 Glass k = 8 Polyethylene k = 3

    As the ability of a capacitor to accommodate the charge of electrons. Coulombs in the 18th century calculated that 1 coulomb = 6.25 x 1018 electrons. Then Michael Faraday postulated that a capacitor will have a capacitance of 1 farad if with a voltage of 1 volt it can carry a charge of 1 coulomb of electrons.

    With the formula it can be written:

    Q = CV

    With assumption :

    Q = electron charge C (Coulomb)

    C = capacitance value in F (Farad)

    V = high voltage in V (Volts)

    In the practice of making capacitors, the capacitance is calculated by knowing the area of ​​the metal plate (A), the distance (t) between the two metal plates (dielectric thickness) and the dielectric constant (k) of the material. With the formula can be written as follows:

    C = (8.85 x 10^-12) (k A/t)


    How capacitors work

    The way a capacitor works in a circuit is to flow electrons into the capacitor. When the capacitor is filled with electrons, the voltage will change. Furthermore, electrons will exit a capacitor and flow into the circuit that needs it. That way, the capacitor will generate a reactive circuit.

    But we do not deny, even though a capacitor component has a different shape and size, the function of a capacitor is still very much needed in an electronic component or even an electronic circuit.

    As for the two plates or plates in a capacitor separated by an insulator, basically no electrons can cross the gap between the two plates. When the battery is not connected, the two pieces will be neutral (uncharged). When the battery is connected, the point where the wire at the negative end of the pole is connected will repel electrons,

    while the point where the positive pole is connected attracts electrons. The electrons will be scattered throughout the capacitor plates. Momentarily, electrons flow into the right-hand plate and electrons flow out of the left-hand plate; in this condition current flows through the capacitor even though there are no electrons flowing through the gap between the two plates.

    After the outside of the chip is charged, it will gradually reject the new charge from the battery. Therefore the current in the plates will decrease in magnitude with time until both plates are at the voltage that the battery has. The plate on the right will have an excess of electrons which is measured with a charge of -Q and on the plate on the left it is charged with +Q .


    How is a capacitor made?

    • If two or more plates are facing each other and are limited by insulation, then the plate is electrified, a capacitor will be formed (the insulation that limits the two plates is called a dielectric).

    • The dielectric materials used are different, so the naming of capacitors is based on the dielectric material. The area of ​​the plate opposite the dielectric material and the distance between the two plates affect the capacitance value.

    • In a circuit that does not occur stray capacitors. Such a property is called parasitic capacitance.The cause is the presence of adjacent components in adjacent electrical conductor lines and adjacent coils of wire. The picture above shows that there are two plates that are bounded by air. The distance between the two plates is expressed as d and the input voltage.

    Capacitance

    The capacity of a capacitor is the ratio of the amount of electric charge to the voltage across the capacitor. C = Q / V If calculated by the formula C = 0.0885 D/d. Then the capacity in units of pico farads D = the area of ​​the plates facing each other and influencing each other in cm2. d = distance between plates in cm. If the voltage between the plates is 1 volt and the magnitude of the electric charge on the plates is 1 coulomb, then the ability to store electricity is called 1 farad. In reality capacitors are made with units below 1 farad. Most electrolytic capacitors are manufactured from 1 microfarad to several millifarads.


    Capacitor Formula

    The Capacitor Formula consists of several formulas that are used to calculate the amount of electric charge both generated by the capacitor and the incoming electric charge. The following are some formulas about capacitors with parallel circuits, series circuits and series and parallel capacitor circuits whose units of calculation are farads (F). The following are the formulas that are stored in the pieces of an electrically charged capacitor as follows:

    Here is an Example of the Capacitor Formula Rumus

    Explanation:

    Q = Charge in Coulombs
    C = Capacity in Farads
    V = Voltage in Volts
    (1 Coulomb = 6.3*1018 electrons)

    The capacitor can function as a battery because the voltage remains in the capacitor even though it is not connected, the length of the remaining voltage depends on the capacity of the capacitor itself. Examples of other formulas in a capacitor circuit:

    • Formula for Capacitors with Parallel Circuit 

    C Total = C1 + C2 + C3

    In the Capacitor Formula above it can be concluded that, in the parallel capacitor circuit there is no division for voltage or electric charge at all, all voltages will have the same amount at every point in the parallel capacitor circuit the reason is because at the same point the parallel capacitor is connected , so it has no significant changes.

    • Formula for Capacitors with Series Circuit

    1/C Total = 1/C1 + 1/C2 + 1/C3

    In the formula for a capacitor with a series circuit above, it can be concluded that, at each measurement of this series capacitor, there is a voltage distribution from the voltage source to each point, which in the end when combined by adding up the voltages from each point it will look the same as the sum of the voltages. from the voltage source.

    • Series and Parallel Capacitor Formulas

    C Total = (C1 + C2) // C3
    1/CA = 1/C1 + 1/C2 (tie)

    In the Capacitor Formula with series and parallel circuits above, it can be concluded that this type of circuit can be calculated by combining several equations that can be seen from the two capacitor formulas, namely series and parallel. So we can find out the total number of combinations between these 2 types of capacitors.


    Capacitor Circuit

    Capacitor circuit is divided into two, namely series circuit and parallel circuit. The calculation method is almost the same as for series and parallel circuits on resistors. The following is the equation of the capacitor circuit.

    Series circuit

    The series circuit on a capacitor is a capacitor circuit by connecting the NOT similar poles between the capacitors, as shown in the following figure:

    The replacement capacity in a series circuit is:

    tot = 1 C 1 + 1 C 2 + 1 C 3
    tot = Q 1 = Q 2 = Q 3
    tot = V 1+ V 2+ V 3

    The series arrangement of capacitors is that the capacitors are arranged in one unbranched connecting line. If a capacitor is arranged in series, the total replacement capacitor can be determined from all the capacitors in the series circuit. In this series arrangement the following rules apply:

    • The charge on each capacitor is equal to the sum of the charges on the replacement capacitor.
    s = Q 1 = Q 2 = Q 3 = Q 4 
    • The potential difference (V) across the ends of the replacement capacitor is equal to the potential difference across each capacitor
    Vs = V1 + V2 + V3 + V4
    • The capacity of the replacement capacitor can be found by the formula
    Cs = 1/C 1 + 1/C 2 + 1/C 3 + 1/C 4
    • For n capacitors with the same capacity, you can use the quick formula
    Cs = C/n

    What needs to be remembered because the replacement capacity of the series arrangement of several capacitors is always smaller than their respective capacity, so capacitors arranged in series can be used to reduce the capacity of a capacitor.

    Parallel Circuit

    Parallel circuit is a series of capacitors by connecting the SAME poles between the capacitors, as shown in the following figure:

    The replacement capacity in a parallel circuit is:

    tot = C 1+ C 2+ C 3
    tot = Q 1+ Q 2+ Q 3
    tot = V 1 = V 2 = V 3

    • The charge on the replacement capacitors is equal to the sum of the individual capacitors (same as the voltage in a series circuit)
    Qp= Q1 + Q2 + Q3 + Q4 + dst…
    • The potential difference of each capacitor is equal to the potential difference of the original source (same as the charge in a series circuit)
    Вп = В 1 + В 2 + В 3 + В 4
    • The capacitance of the replacement capacitor in a parallel circuit is equal to the sum of the total capacitances of the capacitors in the circuit.
    Cp = C1 + C2 + C3 + C4

    Because the replacement capacity of all parallel circuits is always greater than that of each capacitor in the circuit, so parallel arrangement can be used to increase the capacity of the capacitor.

    Combined Series and Parallel

    This arrangement is a combination of series and parallel arrangement. The formula that applies is the same as the formula that applies to the two previous types of circuits. Here, my friend must be shrewd in identifying from a series of combinations which are series and which are parallel. The following is a simple example of a combined circuit

    Capacitor Energy

    An electric charge creates an electric potential and work is required to move it. To charge a capacitor requires electrical work, and this electrical work is stored in the capacitor as energy. The loading starts from zero to Q coulomb. The energy equation for the capacitor can be written as:

    W = 12 CV 2 = 12 QV = 12 Q 2 C

    information :

    W = energy of the capacitor

    Q = Electric Charge ( C )

    V = Electric potential


    Capacitor Type

    According to the type, capacitors can be divided into 2 types, namely:

    Fixed capacitor

    Fixed capacitor is a capacitor whose capacitance value cannot be changed and the value has been set by the manufacturer. The shape and size of the capacitor still vary and differ from one another depending on the material of manufacture.

    Fixed capacitors are also divided into 2, namely:

    • Polar capacitor

    1) Electrolytic capacitor

    This capacitor is a type of polar capacitor or has 2 poles on the legs. The long leg is the positive pole and the short leg or the leg that has a special sign is the negative leg. The installation of electrolytic capacitors in electronic circuits should not be reversed, especially for DC current circuits but for AC current it is not a problem.

    This capacitor should not be exposed to excessive heat during the soldering process because the electrolyte contained in the capacitor can boil and cause the capacitor to be damaged. The following is a picture of an electrolytic capacitor. These capacitors are available with a large enough capacity, the smallest having a capacity of 0.1 microFarrad and the largest commonly available on the market is 47000 microFarrad. But the author has encountered this capacitor in the size of 1 Farrad at a price that is enough to make the bag dry. The working voltage of this capacitor is very diverse but is usually written on the capacitor body. Its working voltage ranges from 6.7 V to 200 Volts.

    2) Tantalum capacitor

    In accordance with technological developments in the field of electronics, electronic component manufacturers are always creating new inventions in the form of capacitor components that have high reliability. In general, these capacitors are made with a small physical shape and are red or green in color. Because they have high reliability, tantalum capacitors are quite expensive.

    • Non-polar capacitor

    1) Ceramic capacitor

    Named ceramic capacitors, because these capacitors are made of ceramic dielectric material. Ceramic capacitors come in various shapes and sizes. This capacitor is stable enough that it is often used in electronic circuits. The capacitance value of this capacitor is usually written in color code, but there are also those that are written directly on the body using numbers.

    2) Polyester capacitor

    The role of plastic is not limited to making bags or household appliances, but also plays a role in the manufacture of electronic components, namely capacitors. Plastic capacitors are very popular in their use and in the field of electronics known as polyester capacitors. In general, these capacitors are made with a small and flat shape. This capacitor does not have a polarity so the installation will not be difficult. The inclusion of the capacitance is usually in color code.

    3) Mica capacitor

    Mica capacitors are components that were born since the first generation and are still widely used today because of their high reliability in addition to having stable properties and low tolerance. As the name implies, this capacitor is made of mica. The use of this type of capacitor is in circuits associated with high frequencies. The capacitance of this capacitor is 50 to 10,000 F

    4) Film capacitor

    Film capacitors, the dielectric is made of film. The amount of capacitance is listed with a color coded in the form of a bracelet and the reading method is almost the same as reading the resistor color code.

    5) Paper capacitor

    It is called a paper capacitor because the dielectric material is made of paper. This type of capacitor has been born since the first generation where at that time still using a vacuum tube. This type of capacitor is now rare and almost not used anymore. In the installation of this capacitor will not be a problem because it is not equipped with polarity. The capacitance of this type of capacitor is 100 pF to 6800 pF.

    Capacitor is not fixed (Variable)

    A variable capacitor is a capacitor whose capacitance value can be adjusted as needed. The types of variable capacitors are;

    • Variable capacitor (Varco)

    Variable capacitors are a type of capacitor that are larger than fixed capacitors. In accordance with its physical form, the variable capacitor has a large capacitance. Capacitors of this type were made in the first generation. Variable capacitors are widely used in large circuits. The capacity of this type of capacitor usually ranges from 1 F to 500 F.

    • Trimer Capacitor

    The trimer capacitor is a variable capacitor that has been developed from the previous variable capacitor which has a small size, so because it has a small size this capacitor is very suitable to be installed in today’s modern circuits.

    Trimmer capacitors are equipped with presets, which are tools used to adjust the amount of capacitance. The adjustment can be done using a screwdriver. This type of variable capacitor uses a dielectric material, namely mica or plastic. The capacitance of this type of capacitor is 5 to 30 F

    • Active capacitor or CDS

    Technological developments in the field of electronics are currently growing rapidly so that now many components are appearing that are getting smaller but have better functions than before.

    Likewise with capacitor components, currently active types of capacitors have been developed, meaning that these capacitor components will actively flow charge when exposed to light, either sunlight or other light sources. These components are widely used as sensors in garden lighting circuits or alarm circuits or functions as an automatic switch.


    Capacitor Function

    Capacitor function is needed in an electronic component. Capacitors are electronic components that function to store electric charge, besides that capacitors can also be used as frequency filters. The capacity to store the ability of a capacitor in an electric charge is called Farad (F) while the symbol for a capacitor is C (capacitor).

    The function of the capacitor itself is divided into 2 groups, namely capacitors that have a fixed capacity and capacitors that have a capacity that can be changed or in other words variable capacitors. The basic nature of a capacitor is that it can store an electric charge, and for DC current the capacitor functions as an insulator / retainer of electric current, while for AC current the capacitor functions as a conductor / passes electric current.

    In its application the capacitor is used as a filter, DC voltage leveler which is used to change the AC voltage to DC, AC wave generator or oscillator and so on, and can also function as impedance (resistance whose value depends on the given frequency), to save power. electricity in fluorescent lamps.

    The function of a capacitor  in an electronic circuit is as a coupling, a filter in a power supply circuit, a phase shifter, a frequency generator in an oscillator circuit and is also used to prevent sparks in a switch.

    • To temporarily store current and voltage
    • As a filter or filter in an electronic circuit such as a power supply or adapter
    • To eliminate the bounce (sparks) when installed on the switch
    • As a coupling between one electronic network and another electronic network
    • To save electricity when installed in fluorescent lamps
    • As an insulator or electric current barrier for DC or direct current
    • As a conductor or conduct electric current for AC or alternating current
    • To even out the DC voltage waveform in the AC to DC voltage converter circuit (adapter)
    • As an oscillator or AC wave generator (alternating) and so on

    Examples Types of Capacitors

    Tantalum Capacitor

    Tantalum Capacitor Is a type of electrolytic capacitor whose electrodes are made of tantalum material . This component has a polarity, how to distinguish it by looking for the + sign on the body of the capacitor, this sign indicates that the pin underneath has a positive polarity. It is expected to be careful in the installation of components because they should not be upside down. The temperature and frequency characteristics are better than electrolytic capacitors made of aluminum.

    Ceramic Capacitor

    The capacitor uses titanium acid barium for its dielectric. Because it is not constructed like a coil, this component can be used in high frequency circuits. The frequency response characteristics need to be taken into account, especially if the capacitor operates at high frequencies.

    For frequency response calculations, the unit of quality factor Q ( quality factor ) is also known which is nothing but 1/DF. Usually used to pass high frequency signals to ground . This capacitor is not good for analog circuits, because it can change the shape of the signal. This type has no polarity and is only available with very small capacitor values.

    Electrolytic Capacitor

    The electrolytic capacitor group consists of capacitors whose dielectric material is a metal-oxide layer. The electrode of this capacitor is made of aluminum which uses a thin oxidation membrane. Generally, capacitors belonging to this group are polar capacitors with + and – signs on their bodies. From these characteristics, the user must be careful in its installation in the circuit, do not turn it upside down. If the polarity is reversed it will be damaged and even “explode”.

    To get a large surface, this Aluminum plate material is usually rolled radially. So that way can be obtained capacitors with large capacitance. Usually this type of capacitor is used in power supply circuits , low pass filters , and timer circuits.

    This capacitor cannot be used in high frequency circuits. Usually the working voltage of the capacitor is calculated by multiplying the power supply voltage by 2. For example, the capacitor will be supplied with a power supply of 5 volts, meaning the selected capacitor must have a minimum working voltage of 2 x 5 = 10 volts.

    Multilayer Ceramic Capacitor

    The material for this capacitor is the same as the type of ceramic capacitor, the difference is in the number of layers that make up the dielectric. In this type the dielectric is arranged in many layers or usually called a layer with a thickness of 10 to 20 m and the electrode plate is made of pure metal.

    Besides being small in size and having better temperature characteristics than ceramic capacitors, this type is usually good for applications or passing high frequencies to ground.

    Polyester Film Capacitor

    The dielectric in this capacitor is made of polyester film . Has better temperature characteristics than all the above types of capacitors. Can be used for high frequency. Usually this type is used for circuits that use high frequencies, and analog circuits. These capacitors are usually called mylars and have a tolerance of ±5% to ±10%.

    Polypropylene Capacitor

    The capacitor in addition has a higher tolerance value than the polyester film capacitor . In general, the capacitance value of this component will not change if it is designed in a system if the frequency through it is less than or equal to 100kHz.

    The picture above shows a polypropylene capacitor with a tolerance of ±1%. This type of capacitor is still under development to get a large but small and light capacitance, for example for electric car applications.

    Mica Capacitor

    This type uses mica as its dielectric material. Mica capacitors have a high level of stability, because of their low temperature coefficient. Because the frequency characteristics are very good, usually these capacitors are used for resonant circuits, filters for high frequencies and circuits that use high voltages, for example: radio transmitters that use transistor tubes. Mica capacitors do not have a high capacitance value, and the price is also relatively high.

    Polystyrene Film Capacitor

    The dielectric of this capacitor is polystyrene film . This type can not be used for applications that use high frequencies, because the construction is the same as an electrolytic capacitor, which is like a coil. These capacitors are good for timer and filter applications that use frequencies of several hundred kHz.

    This component has 2 colors for the electrodes, namely: red and gray. For the red one, the electrode is made of copper, while the gray one is made of aluminum foil.

    Electric Double Capacitor (Super Capacitor)

    This type of capacitor has the same dielectric material as an electrolytic capacitor. However, the difference is that the size of the capacitor is larger than the electrolytic capacitor described above. Usually have units of F. These capacitors have a large voltage limit.

    Because it has a voltage limit and a larger shape than other capacitors, this capacitor is also called a super capacitor. The picture of the physical form can be seen above, in Figure 2.13 the capacitor has a size of 0.47F. These capacitors are usually used for power supply circuits .

    Trimmer Capacitor

    This type of capacitor uses ceramic or plastic as its dielectric material. The value of the capacitor can be changed by turning the screw above it. In the playback is expected to use a special screwdriver, so as not to cause the effect of capacitance between the screwdriver and hand

    Tuning Capacitor

    These capacitors in Japan are referred to as “Varicons”, usually a lot of use as a selector on radio waves. The dielectric type uses air. The capacitance value can be changed by turning the handle on the capacitor body to the right or to the left.

  • Contamination – Definition, Causes, Impact, Countermeasures and Examples

    Contamination – Definition, Causes, Impact, Countermeasures and Examples

    For this discussion we will provide a review of Contamination which in this case includes the Definition of Contamination, Examples of Contamination and Causes of Contamination.

    So in order to better understand and understand see the full review below.

    Definition of Contamination

    So what is meant by contamination? Definition of Contamination is a condition of mixing / contamination of something by other elements that give certain effects, usually a bad impact.

    The components that cause contamination are very diverse, both inanimate objects and living things. Contaminants that come from inanimate objects such as chemical compounds and dirt, while contaminants that come from living things such as microbes.

    And in general, the word contamination is always associated with something that means bad/negative. The use of the word “contamination” is often used for many things, including:

    • Food “food contamination”
    • Environment “environmental contamination”
    • “Cross-contaminating” foodstuffs
    • Language “contamination of words, sentences”

    Microbial Contamination in Foodstuffs

    • Microbial Contamination From Soil

    Soil contains various kinds of microorganisms that can be a source of contamination. If microbiologists want to look for a new type or strain of a microorganism for a particular purpose, they usually first look for it in the soil. Not only a few types, but in large numbers microorganisms are found in fertile soil, which can contaminate plants growing on the soil.

    • Microbial contamination from water

    Water in nature not only contains normal flora but also contains microorganisms originating from the soil and possibly also from animal waste. The water surface of rivers or ponds and the water at the bottom of large lakes and ponds may contain various kinds of microorganisms in units of millions per mm after a rainstorm, which is more numerous than the lake and pond at rest or there is no thunderstorm. Groundwater after spring will exit through layers of soil and rocks: because many bacteria live in the water, the number of bacteria in this water ranges from several hundred per millimeter.

    • Microbial Contamination From the Air

    Food contaminated from the air has an important role in sanitation for economic reasons. Organisms that contain disease, especially those that can cause infections of the respiratory system or in food that causes contamination. The number of microorganisms in food that can come from the air, especially when air is used as aeration in food products, although organisms enter by sedimentation from the air is always not a concern. Airborne mold spores cause problems with cheese, meat, condensed milk, sliced ​​bread and lard.

    Environmental Contamination

    Environmental contamination is contamination of food ingredients caused by environmental conditions that are less well maintained.

    Environment

    • Air: temporary medium for influenza viruses & bacteria
    • Soil : botulinum & C. Perfringens
    • Salmonella, Shigella, faecal Streptococci wastewater ,

    Other Sources:

    • Equipment: during use or storage
    • Equipment contamination from materials, workers and air
    • Overcome with: hygienic design and effective cleaning

    • Water
    1. Water as a cleaning medium Needs special safeguards. For example, ultra violet
    2. Garbage used for washing contains water that has a waste flora
    3. The good places for the bacterial micro-organisms are Clostridium batulinum and Clostridium perfingens. Can be found in the setup and save area in a variety of ways
    4. With food and wrap
    5. With the shoes of the workers
    6. With air (almost every dust belongs to the sewer class

    • Air
    1. Air pollutes processing, packaging, storage and preparation sites ditempat
    2. Polluted air is caused by several factors. Dew drops when talking, sneezing, coughing can be the center of micro-organisms

    • Waste
    1. Poor waste management: sources of contamination
    2. Can pollute water sources, rivers, lakes, seas so that food from these waters can be polluted

    Production place

    1. Judging from the cleanliness of the floor used, if there is standing water it can be a source of contamination in food.
    2. Door handles contaminated with workers’ hands, processing equipment surfaces contaminated with microbes, can contaminate the product being processed.
    3. On the walls that are dirty and not cleaned as a breeding ground for microbes
    4. On the tools used in the cooking process

    Product raw materials

    Contamination contained in the raw food product itself. Prior to the processing, the product has been contaminated with bacteria, this can be caused by unfavorable environmental conditions, bacteria present in the animal (eg cattle affected by anthrax), raw material handlers who are less hygienic (cross contamination)

    • Contaminants from raw materials:
    1. Microbes from soil, water, pesticide residue
    2. Animals: microbiology, antibiotics, hormones
    • Meat
    • salmonella
    1. Knives and tools when slaughtering
    2. Hair, skin, digestive tract, respiratory tract.
    3. Contamination during: slaughtering, cutting, processing, storage and distribution
    4. Carcass contact with dust or other debris
    • Milk
    1. Cow, milker
    2. Cross contamination: worker, container

    Examples of contamination due to human activities; Factory waste is dumped into rivers so that river water becomes toxic to living things. Examples of contamination due to natural activities; volcano erupts, natural gas is poisonous.

    Cross Contamination

    The definition of cross-contamination is the transfer of bacteria from raw food ingredients to finished food products, either directly or indirectly. Cross-contamination generally occurs due to the process of storing foodstuffs and the process of making food that is not clean.

    An example of cross-contamination occurs when a dirty knife contaminated with harmful substances is used to peel a mango that is about to be eaten. Another example, plastic storage contaminated with feces is used to store meat.


    Causes of Contamination

    In general, there are three causes of contamination, namely biological contamination, chemical contamination and physical contamination.

    • Biological contamination, some of the causes of biological or microbiological contamination are “protozoa and worms” parasites, viruses, pathogenic bacteria, which can cause poisoning and infection in humans.
    • Chemical Contamination, chemicals that can cause intoxication in humans. Some of the chemicals that cause poisoning include antibiotics, pesticide residues, industrial chemical contamination.
    • Physical Contamination, contamination of a physical nature, such as stones, dust, hair, metal, pieces of wood, nails or even cooking utensils used. Physical contamination does not always cause disease, but it is still dangerous and interferes with human health

    Impact of Physical Contamination

    In general, food contamination can cause many health problems for people who eat contaminated food. Among them can cause disturbances in the digestive tract, kidneys, liver, heart, and other organs. In addition, food contamination can also cause food poisoning.

    Physical contamination in the form of foreign objects if swallowed with the food or drink we consume will certainly be very dangerous for our bodies. For example, if there is broken glass that enters our body, it will certainly injure our organs and can even cause death.


    Physical Contamination Prevention Efforts

    Some actions that can be taken to prevent or avoid food contamination include the following:

    Personal Hygiene

    People who process, cook, or serve food need to understand and understand that cleanliness is the basis of health. Patients with scabies (scabs), inflammation of the respiratory tract, or digestive tract diseases are sources of transmitting germs to food, especially to cooked food. The ways of transmission are through touching with dirty hands, sneezing, and coughing. Washing hands with clean water is an absolute requirement for food handlers, especially after urinating or defecating.

    Environmental Hygiene

    In addition to personal hygiene, cleanliness of the workplace and the surrounding environment, workplace facilities are equally important. There must be enough clean water available, enough sunlight. Food processing and storage must receive special attention where the food processing area must be in a clean condition. In addition, cooking utensils and cutlery must also be kept clean so that they do not become a source of bacteria.

    Tools should be cleaned as well as possible so that no organic remains are visible to the eye. This action can be helped by using detergent and if this material is used it must be washed / rinsed well with clean water. wash foodstuffs, such as meat and vegetables under running water when they are freshly purchased, to remove chemicals, pesticides, and germs.

    At the Food Ingredients Selection Stage

    Materials that are eaten raw must be transported and stored separately from other raw materials and non-food ingredients. So as to minimize contamination by foreign objects.

    At the Food Storage Stage

    Storage must be done in a special place that is clean and meets the requirements. Items must be arranged properly so that they are easy to take, do not allow insects or rats to nest, avoid flies/rats and for perishable or damaged products to be stored at a cold temperature. . And each food ingredient is placed separately according to its type.

    At Food Processing Stage

    Food processing is the process of changing the shape of raw materials into ready-to-eat food. Good food processing is one that follows the rules and principles of good hygiene and sanitation in the washing process, food handling, cooking process, use of food additives and use of cooking utensils.

    In Food Storage Stage

    Food that has been cooked or is ready to be served, not all of it is directly consumed by us, especially food that comes from catering or catering services. Some things to consider when storing cooked food include:

    1. Food served hot should be kept at a temperature above 60 degrees Celsius.
    2. Food that will be served cold is stored at a temperature below 4 degrees Celsius
    3. Food served in hot conditions stored at a temperature below 4 degrees Celsius must be reheated to 60 degrees Celsius before serving.

    At Food Transport Stage

    Healthy food transportation will play a very important role in preventing food contamination. Contamination of cooked food is higher risk than food contamination. Therefore, the emphasis is on controlling food contamination in cooked food.

    At the Presentation Stage

    The presentation of food must be in accordance with the principles of food hygiene and sanitation, so that there is no contamination of the food to be served.

    Tackling Contamination

    How to deal with contamination of toxic and hazardous materials:

    • When exposed to corrosive liquid

    Immediately washed with water repeatedly on the affected, before being taken to the ER to be treated by a doctor.

    • When exposed to solid corrosive materials

    Immediately wash with water repeatedly on the affected area, if necessary with soapy water.

    • When burns due to chemicals

    Immediately avoid these chemicals and wash them with water repeatedly and immediately be treated by an emergency room doctor.

    • Burns due to heat

    First aid can be done by compressing ice water or pouring water until the pain goes away and does not come back. If necessary soak in water. Cooling relief measures can be taken to relieve pain and more importantly that cooling will be stopped or slow the reaction of the destruction of body tissues due to fire. This first aid must be followed immediately by a doctor’s treatment.

    Clothing that is attached to or adjacent to the burn needs to be removed, avoid contamination of the wound and do not clean the wound or apply topical agents, such as butter, oil, soy sauce and toothpaste. Cover the wound with a sterile, clean cloth or bandage that is treated by a doctor.


    Example of Contamination

    Examples of physical contamination include: dust, soil, stones, glass, hair, staples, klips, animal waste, safety pins, needles, leaves, parts of animals such as fur or animals such as lizards, insects and so on. Sources of physical pollutants can occur in conditions where food processing is not clean, storage of foodstuffs and ready-to-eat food is not good so that dust and soil are possible as well as contamination by rats and insects, the presence of pets such as cats, chickens and birds in food processing areas. can cause physical contamination of food.

    Likewise, humans who manage food that do not use work clothes, good hair cover and how to wash cooking utensils and storage can cause contamination by human hair and dust .

    Understanding Databases and Software

    Understanding Databases

    Database is a collection of information stored in a computer systematically so that it can be checked using a computer program to obtain information from the database. Database is a representation of a collection of interconnected facts stored together in such a way and without unnecessary repetition (redundancy), to meet various needs.

    The database is a collection of interrelated information on a particular subject for a specific purpose. Database is an arrangement of complete operational data records of an organization or company, which is organized and stored in an integrated manner using certain methods on a computer so that it is able to meet the optimal information needed by users.

    Database (database) or as a database is a collection of information stored in a computer system systematically so that it can be checked using a computer program in order to obtain information from the database. The software used to manage and call database queries is called a database management system (database management system, DBMS). In a database system, it can be studied in information science.

    The term database originated from computer science, although later it meant more broadly to include things outside the field of electronics. For similarities in this database actually existed before the industrial revolution, namely in the form of ledgers, receipts and data collections related to business.


    Origin of the term database

    The term “database” has its origins in computer science. Although later the meaning became wider, including things outside the field of electronics, this article is about computer databases. Records similar to databases actually existed before the industrial revolution in the form of ledgers, receipts and collections of business-related data.

    The term database refers to a collection of related data and the software should refer to it as a database management system (DBMS). If the context is clear many administrators and programmers use the term database for both meanings.


    Database System Components 

    The database is a system consisting of a collection of interconnected files or tables and a Database Management System (DBMS) that allows multiple users to access and manipulate these files . The database system has several components, namely:

    1. Hardware

    The hardware that is usually contained in a database system is a secondary hard disk memory.

    2. Operating system

    Operating system is a program that activates or functions a computer system, controls all resources (resources) and performs operations on a computer. Operating systems are widely used such as: MS-DOS, MS-Windows 95 MS Windows NT, and Unix.

    3. Database

    A database  can have several databases. Each database can contain or have any number of database objects such as files or tables. Database Management System (DBMS).

    Physical database processing is not carried out by the user directly, but is handled by a software called a DBMS which determines how data is stored, modified and retrieved.

    4. Users (Users)

    For users to interact with the database and manipulate data in programs written in programming languages.

    Database System Components : hardware, software, data, user

    Basic Concepts of Database

    The basic concept of a database is a collection of records, or chunks of knowledge. A database has a structured description of the types of facts stored in it: these descriptions are called schemas. A schema describes the objects that a database represents, and the relationships between these objects. There are many ways to organize schemas, or model the structure of a database: these are known as database models or data models.

    The model that is commonly used today is the relational model, which according to the term represents all information in the form of interconnected tables where each table consists of rows and columns (the actual definition uses mathematical terminology). In this model, relationships between tables are represented by using the same values ​​between tables. Other models, such as the hierarchical model and the network model, use a more explicit way of representing the relationships between tables.

    The basic concept of a database is a collection of records or a piece of knowledge. A database has a structured explanation of the types of facts stored in it, the explanation is with a schema. Schema describes an object that is represented by a database and has a relationship between these objects. There are many ways to organize schemas or model database structures, these are known as database models or data models. Usually the model that is commonly used today is the relational model whose term layman represents all information in the form of interconnected tables where each table consists of rows and columns (the actual definition uses mathematical terminology). In this model the relationship between tables is represented by using the same values ​​between tables.


    Database Creation Tool

    Databases can be created and processed using a computer program, which is what we usually call software. The software used to manage and call database queries is called a Database Management System (DBMS) or if translated into Indonesian it means “Database Management System”.

    DBMS consists of two components, namely Relational Database Management System (RDBMS) and Overview of Database Management System (ODBMS). RDBMS includes Interface Drivers, SQL Engine, Transaction Engine, Relational Engine, and Storage Engine. While ODBMS includes Language Drivers, Query Engine, Transaction Engine, and Storage Engine.

    As for the level of the software itself, there are two levels of software that allow us to create a database, namely High Level Software and Low Level Software. Included in the High Level Software are Microsoft SQL Server, Oracle, Sybase, Interbase, XBase, Firebird, MySQL, PostgreSQL, Microsoft Access, dBase III, Paradox, FoxPro, Visual FoxPro, Arago, Force, Recital, dbFast, dbXL, Quicksilver, Clipper, FlagShip, Harbor, Visual dBase, and Lotus Smart Suite Approach. Meanwhile, included in the Low Level Software include Btrieve and Tsunami Record Manager.


    12 Database Type

    There is 12 database type, such as Operational database, Analytical database, Data warehouse, Distributed database, End-user database, External database, Hypermedia databases on the web, Navigational database, In-memory databases, Document-oriented databases, Real-time databases, dan Relational Database.

     

    1. Operational database

    This database stores the detailed data needed to support the operations of the entire organization. They are also called subject-area databases (SADB), transaction databases, and production databases. Example: customer database, personal database, inventory database, accounting database.

    2. Analytical database

    This database stores data and information retrieved from selected operational and external databases. They consist of summarized data and information most needed by an organization’s management and other End-users. Some people refer to multidimensional analytical databases as databases, database management, or database information.

    3. Data warehouse

    A data warehouse stores data from current and previous years – data retrieved from various operational databases of an organization. The data warehouse is the primary source of data that has been vetted, edited, standardized and integrated so that it can be used by managers and other end users across professional organizations. The latest development of the data warehouse is that it is used as a Shared nothing architecture to facilitate extreme scaling.

    4. Distributed database

    These are databases of local workgroups and departments in regional offices, branch offices, factories and other work sites. This database can include both operational and user database segments, as well as data generated and used only on site users themselves.

    5. End-user database

    This database consists of various data files developed by end-users on their workstations. Examples of this are document collections in spreadsheets, word processing and even file downloads.

    6. External database

    This database provides access to external, privately owned data online – available for a fee to end users and organizations of commercial services. Access to a wealth of information from external databases available for a fee from commercial online services and with or without charge from many sources on the Internet.

    7. Hypermedia databases on the web

    This is a collection of interconnected multimedia pages on a website. They consist of the home page and other hyperlinked pages of multimedia or mixed media such as text, graphics, still images, video clips, audio etc.

    8. Navigational database

    In database navigation, queries find objects primarily by following references from other objects.

    9. In-memory databases

    mainly rely on main memory for computer data storage. This is in contrast to database management systems that use disk-based storage mechanisms. Main memory databases are faster than disk optimized databases since Internal optimization algorithms become simpler and fewer CPU instructions execute. Accessing data in memory provides faster and more predictable performance than disk. In applications where response time is critical, such as telecommunications network equipment operating emergency systems, main memory databases are frequently used.

    10. Document-oriented databases

    Document-oriented databases are computer programs designed for document-oriented applications. This system can be implemented as a layer on top of a relational database or object database. As opposed to relational databases, document-based databases do not store data in tables with uniformly sized columns for each record. Instead, they store each record as a document that has certain characteristics. Any number of long fields can be added to the document. A field that can also contain multiple pieces of data.

    11. Real-time databases

    Real-time databases are processing systems designed to handle state workloads that can change constantly. It differs from traditional databases which contain persistent data, largely unaffected by time. For example, the stock market changes rapidly and dynamically. Real-time processing means that transactions are processed fast enough for results to come back and act immediately. Real-time database that is useful for accounting, banking, legal, medical records, multi-media, process control, reservation systems, and scientific data analysis.

    12. Relational Database

    The standard for business computing since 2009, the relational database is the most commonly used database today. Use tables for structure information so it’s easy to find.


    Database Models

    The database has two model variants, namely the Post-relational database model and the Object database model.

    1. Post-relational database models

    A product that offers a data model that is more general than the relational model and is known as post-relational. The data model in the product includes relationships but is not limited by the Information Principle which represents all information with data values ​​in relation to it. Some of these extensions to the relational model actually integrate concepts from technologies that pre-date the relational model.

    For example, they allow the representation of a directed graph with trees on nodes. Some products implementing this model do so by extending the relational database system with non-relational features. Others, on the other hand, have arrived at the same place by adding relational features to pre-relational systems. Surprisingly, this allows products that are historically pre-relational, such as PICK and hyacinth, to make reasonable claims to be post-relational in today’s architecture.

    2. Object database models

    In recent years, object-oriented paradigms have been applied in fields such as engineering and spatial databases, telecommunications and other scientific sciences. The conglomeration of object-oriented programming and database technologies led to a new programming model known as Object databases. These databases seek to bring the database world and the application-programming world closer together, in particular by ensuring that the database uses the same type of system as the application program.

    This is to avoid the overhead (sometimes referred to as an impedance mismatch) for converting information between its representation in the database (for example as rows in a table) and its representation in the application program (usually as objects). At the same time, object databases seek to introduce key ideas from object programming, such as encapsulation and polymorphism, into the database world.

    Various ways have been tried to store objects in the database. Some products run into problems from the application programming side, with objects being manipulated by the program constantly. This also usually requires the addition of some kind of language query, because conventional programming languages ​​do not provide language level functionality for finding objects based on their information content.


    Database Design Stage

    Database design (database) is an effort to build a database in a business environment, to build a database there are stages that need to be passed, namely:

    • Database planning (database)
    • Define system
    • Analyze and collect needs
    • Database design (database)
    • Application design
    • Make a prototype
    • Implementation
    • Data conversion
    • Test
    • Operational maintenance

    Database Software (Database)

    Database software (database) that is widely used in programming

    1. MySQL

    Is a software on a SQL database management system or DBMS (database management system) that is multithreaded, multi-user, with about 6 million installations worldwide. MySQLAB makes MySQL available as free software under the GNU General Public License (GPL) but they also sell under a commercial license for cases where its use is incompatible with the use of the GPL. Unlike projects like Apache where software is developed by the general community, and the copyright for the source code is owned by the respective authors, MySQL is owned and sponsored by a Swedish commercial company MySQL AB, which holds the copyright to almost all of the source code. . The two Swedish and one Finnish who founded MySQL AB is David Axmark.

    2. Microsoft SQL Server

    A relational database management system (RDBMS) Microsoft product. Its primary query language is Transact-SQL which is an implementation of the ANSI/ISO standard SQL used by Microsoft and Sybase. In general, SQL Server is used in the business world that has small to medium-sized databases, but then grew with the use of SQL Server on large databases. Microsoft SQL Server and Sybase/ASE can communicate over the network using the TDS ( Tabular Data Stream ) protocol. Apart from that, Microsoft SQL Server also supports ODBC (Open Database Connectivity) and has a JDBC driver for the Java programming language. Another feature of SQL Server is its ability to create database mirroring and clustering.

    3. Relational Database Management System ( RDBMS )

    MySQL is a Relational database management system (RDBMS) which is distributed free of charge under the GPL (General Public License) where everyone is free to use MySQL but may not be used as a commercial derivative product. MySQL is actually a derivative of one of the main concepts in databases for a long time, especially for the selection or selection and entry of data that allows data operations to be done easily automatically. The reliability of a database (DBMS) can be seen from how the optimizer works in processing SQL commands made by the user and its application programs. As a database server, MySQL can be said to be superior to other database servers in querying data. This is evident for queries made by a single user,

    4. Clipper

    It is a programming language for the XBase family of computers that is used to create computer programs that run primarily on the DOS operating system. More specifically, the clipper is generally used to create programs related to databases/businesses, such as savings/loan management, accounting and others. The history of the clipper was first introduced in 1985 by Nantucket which was then sold to Computer Associates as a compiler for Dbase III which was very popular at that time. Compiling Dbase codes means changing them from interpreting code (human-readable source code) that the computer has to interpret each line run, to P-code (or pseudo-code) that uses a virtual machine to process the p-code that is generated. have compiled it.

    5. DBASE

    A database management system (DBMS) widely used on microcomputers introduced by Ashton-Tate for the CP/M computer and later for the Apple II, Apple Macintosh and IBM PC platforms with DOS being one of the best-selling software for several years. at the time. The inability of dBASE to transition to newer operations, Microsoft Windows eventually made use of dBASE replaced by other newer products such as Paradox, Clipper, Foxpro and Microsoft Access. Ownership of Dbase was eventually sold to Borland in 1991 and in 1999 Borland sold the rights to the dBASE product line to a new company Dbase Inc. Starting from the mid-1980s many vendors created dialects or variations on their products or in their own languages. These included FoxPro (now known as Visual FoxPro), Quicksilver, Clipper, Xbase++, Flagship, and Harbor. They are what information is known or referred to as xBase or Xbase. The basic dBase file format, known as file.dbf, is currently one of the widely used formats by many applications that require a simple format for storing structured data. Dbase is licensed to its users for a period of five years during which it is not possible for the user to operate Dbase during that period. dbf, is currently one of the widely used formats by many applications that require a simple format to store structured data. Dbase is licensed to its users for a period of five years during which it is not possible for the user to operate Dbase during that period. dbf, is currently one of the widely used formats by many applications that require a simple format to store structured data. Dbase is licensed to its users for a period of five years during which it is not possible for the user to operate Dbase during that period.

    6. Firebird

    Firebird or also called FirebirdSQL is a relational database management system that offers the features contained in the ANSI SQL-99 and SQL-2003 standards. This RDBMS runs both on Linux, Windows and on a number of Unix platforms. Firebird is directed and maintained by the FirebirdSQL Foundation. It is a derivative of Borland’s open source version of Interbase. New code modules added to Firebird are licensed under the Initial Developer’s Public License (IDPL) while the original modules released by Inprise are licensed under the InterBase Public License1.0. both licenses are modified versions of the Mozilla Public License 1.1.


    Data Base Management System (DBMS) Function

    A system is needed to integrate data files into a file so that it can serve different users. hardware and software and procedures that manage the database management system.

    1. Provides a quick access system.
    2. Reduce data redundancy and redundancy.

  • Biology – How Enzymes Work

    Biology – How Enzymes Work

    You has been chewing rice for a long time, If you’ve ever done it, surely over time the rice you chew tastes sweet, right? Do you know the reason why the rice can taste sweet? This happens because rice is starch, aka complex carbohydrates, which are the products of plant photosynthesis to store excess glucose.

    Well, when we start chewing rice in our mouths, there is a function of the amylase enzyme from our saliva which breaks down starch in rice into maltose, a simpler carbohydrate group. The way the maltose enzyme works is what has a sweet taste when we chew starch like rice.

    This is what distinguishes rice from sugar. When we eat sugar, the sweet taste of sugar is immediately felt when the sugar enters our mouth. The sweet taste can be felt immediately because sugar is composed of simple carbohydrate compounds.

    While rice, which is a complex carbohydrate, requires the help of the enzyme amylase to create a sweet taste. Eh, but what is an enzyme? What are the functions of enzymes that you know? So that you understand what enzymes are and how they work, let’s just talk about it, let’s go!

    Get to know the function of enzymes and the factors that influence how enzymes work

    Some of you may have been asked to explain how enzymes work, the structure of enzymes and the factors that affect the work of enzymes, right? So, so you don’t get confused, you should pay attention to the following discussion about enzymes:

    enzyme. source: genome.gov

    Relationship of Enzymes, Substrates, and Products

    Enzymes are protein compounds produced by the cells of living things. That’s why humans, animals, and plants have a protein called this enzyme in their bodies. In general, the function of this enzyme is to assist and speed up metabolic processes in the body, which in biology is referred to as a biocatalyst. There are two types of metabolic processes in our body, namely catabolism and anabolism. Catabolism is a metabolic process that breaks down complex substances into simpler ones, while anabolism is a metabolic process that forms complex substances from simple ones.

    Well, the way enzymes work in our bodies has a role in both these metabolic processes. When an enzyme acts, the initial substance before the reaction occurs is called the substrate and the resulting substance is called the product. For example, in the process we eat rice earlier. The starch in rice is the substrate, while maltose is the product.

    Enzyme Nomenclature

    There are many properties of the enzyme, not only amylase that breaks down starch. There are so many enzymes in our body. The function of each enzyme is also different. For example, in addition to the amylase enzyme mentioned earlier, there is also a lipase enzyme whose function is to break down fats and proteases that break down proteins.

    To make it easy to remember, each enzyme name is adjusted to its substrate and is given the -ase suffix. So, if the substrate is starch, the enzyme is called amylase. If the substrate is fat or lipid, the enzyme is called lipase. If it’s protein, it’s a protease, while if it’s fructose, it’s fructose. Now, if the substrate is cellulose, you can guess what the name of the enzyme is, right? Yup! Cellulase. Easy, right, memorizing it?

    you can also read this article from this articel to see human digestion system enzyme

    Enzyme Classification

    Just as we have a place to live, the enzymes in our body also have a place to live in our body. The residence of these enzymes is adjusted to the function of their respective enzymes. There are intracellular enzymes and there are extracellular enzymes.

    Intracellular enzymes are enzymes that reside in living cells. An example is catalase. This catalase enzyme can break down toxins such as hydrogen peroxide (H2O2) into water molecules (H2O) and oxygen (O2) which are harmless to our bodies. Because of this function, the enzyme catalase can mostly be found in liver, heart, kidney, bone marrow, and blood cells.

    Well, if extracellular enzymes are enzymes that live outside the cell. These extracellular enzymes are usually produced by the glands of our body. For example, the amylase enzyme is produced by the salivary glands in our oral cavity. So, this amylase enzyme works outside the body’s cells or extracellularly.

    Enzyme Components and Structure

    Do you know how enzymes can speed up metabolic reactions in living things? To be able to carry out metabolic processes, the body requires a lot of energy. With the presence of enzymes, energy requirements can be reduced because enzymes can accelerate the occurrence of metabolic reactions.

    Before we know how enzymes work, we must first know the parts of enzymes. In terms of shape, enzymes have two sides. There is an active site, where the substrate is bound, and there is an inactive or allosteric site. Then the enzyme is composed of two different components. There are apoenzymes made of protein and there are prosthetic groups made of non-protein material.

    Apoenzyme is the main component of the enzyme that will react with the substrate. Actually, with only apoenzyme enzymes can work, but the reaction will be very slow, aka long. So the enzyme must be equipped with a second component, aka a prosthetic group. This prosthetic group can be made of two types of ions, namely organic ions and inorganic ions.

    If the prosthetic group is an organic ion, the prosthetic group is called a coenzyme. For example, there are vitamin B1, vitamin B2, vitamin H, NAD, and FAD. That’s why vitamins are important for our bodies. Because some of the vitamins we consume help enzymes to work. Well, this coenzyme functions to move chemical groups, atoms, and electrons from one molecule to another, so that the metabolic process becomes smoother.

    But if the prosthetic group is an inorganic ion, then the prosthetic group is called a cofactor. Some of the cofactors present in enzymes are calcium (Ca), chlorine (Cl), sodium (Na), and potassium (K). Well, the cofactor usually pairs with the apoenzyme to form a new structure called the holoenzyme. When this holoenzyme is formed, it goes up one level, so the enzyme can work optimally.

    How Enzymes Work

    When there is a substrate to be broken down, such as starch, for a reaction to occur, the enzyme and the substrate must complement each other, such as a lock and key. We think of this lock as an enzyme and this key as a substrate. So, if you want both to work, the lock and key must be paired. Meanwhile, if the key is wrong, yes, the lock won’t open, right?

    how enzyme work
    how enzyme work source : khan academy

    Likewise with enzymes and substrates. The shape of the substrate must match the active site of the enzyme. If the enzyme does not match the substrate, for example, if we use the amylase enzyme as a protein substrate, the two will not match. If the substrates don’t match, they can’t complement each other because there won’t be a reaction between them. But if the substrate is right, for example starch meets amylase, the enzyme will work.

    In order for the amylase enzyme to break down starch into maltose, the enzyme requires a chloride ion (Cl) cofactor. This ion is like the power button in the enzyme. If the ions are attached, then the amylase enzyme will immediately turn on, work immediately, or the cool language is activated. If it is activated, the amylase enzyme can help break down starch into maltose.

    Well, an enzyme must have a substrate pair. But the substrate can come in various forms. One starch is different from the other, in the form of amylopectin and in the form of amylose. If the shape of the incoming substrate does not match the enzyme, the active site of the enzyme can change to match the substrate, aka flexible.

    But still, yes, even if the active site of an enzyme can change, the enzyme and its substrate must match, in order for it to work. Like amylase and starch earlier. Whatever the form of starch, if you meet the amylase enzyme, yes, they will match each other.

    Enzyme Properties

    Enzymes must have pairs with suitable substrates because enzymes have specific properties. This means that even though there are many substrates, the enzyme will choose a suitable substrate for it, aka already paired. In addition to specific properties, enzymes also have several other properties. The second property is that enzymes can work back and forth. In addition to turning the substrate into a product, enzymes can also turn the product into a substrate again, according to the body’s needs. Then as long as the enzyme is not damaged, the enzyme can be used over and over again. So actually the body only needs enzymes in small amounts. Well, whether or not enzymes work smoothly depends on several factors, such as temperature, pH, inhibitors, and activators.

    Well, now you understand what enzymes are and how enzymes work, right,

  • Gene Mutations And Their Levels

    Gene Mutations And Their Levels

    What happens if our bodies suddenly mutate, huh? Did you instantly turn into Spiderman or Wolverine? Unlike that, don’t imagine examples of gene mutations in humans like in superhero fiction films. Because, a number of cases of gene mutations in humans actually cause abnormalities in the body, you know!

    Well, so that you understand more, in this article, sinaumedia wants to invite you to know about gene mutations, along with examples of gene mutations in humans. Listen to the discussion until it’s finished, yes.

    Definition of Gene Mutation

    Gene mutations are changes that occur in the genetic material in cells. Changes in this material can make changes in properties, both at the cellular level and in living things.

    In people who have gene mutations, the DNA in the cells will undergo changes. These mutations can occur only in DNA or extend to the chromosomes involving several types of genes.

    gene
    gene. source : medlineplus

    Based on changes in the level of occurrence, mutations are divided into gene mutations and chromosomal mutations. The difference between gene mutations and chromosomal mutations lies in the scale of the changes. In gene mutations, only one gene is changed.

    While chromosomal mutations change many genes in it. That is why, chromosomal mutations have a greater effect on the body and can cause more serious abnormalities when compared to mutations at the gene level.

    You need to know, organisms that experience this mutation are usually called mutants. The cause of the mutation is called a mutagen. For example in the fictional Spiderman story, in this film the main character Peter Parker turns into a mutant. While the spider venom that causes mutations is called a mutagen.

    Main Types of Gene Mutations

    There are two main types of gene mutations, namely mutations in the number of bases in the sequence of nitrogenous bases and mutations in the types of nitrogenous bases. These kinds of gene mutations can affect the formation of amino acids that are different from the normal state. So that you understand better, see the following explanation.

    1. Nitrogen Base Mutation

    This mutation occurs due to the addition (addition), reduction (deletion), or doubling (duplication) of nitrogenous bases in the DNA chain of an organism.

    The nitrogenous base mutation can affect the triplet reading of the genetic code in mRNA (messenger RNA). As a result, the amino acids that cells make are different from those that are supposed to be formed.

    For example, there is a DNA chain that has the nitrogenous base sequence CCA–TAA–GCG. This DNA chain will be translated by mRNA, one-third of its nucleotide bases, into the amino acids glycine, isoleucine, and arginine.

    If there is a mutation in the DNA chain, for example there is a T base, thymine, which suddenly increases the front of the chain, the reading of the 3 nucleotide bases will change to TCC-ATA-AGC.

    If you have this, the amino acids that are formed will turn into arginine, tyrosine, and serine. This change in the addition of the thymine nucleotide base in front of the DNA chain is referred to as an addition gene mutation. Not only at the front, the addition of DNA chains can also occur in the middle, yes.

    In addition to mutations in addition genes, changes can also occur if there is a duplication or duplication in the sequence of nucleotide bases in the DNA chain. For example, the beginning of the chain is CCA-TTA-GCG, because the cytosine is duplicated, the chain changes to CCC-ATA-AGC. In this situation, the amino acids formed by the chain will also change.

    Lastly, there is a change in the nucleotide base in the DNA chain which is called a deletion. A deletion is a reduction in the nitrogen sequence in DNA. For example, initially the DNA chain is CCA-TTA-GCG, then the cytosine at the beginning of the chain is deletion and is lost. As a result, the DNA chain will turn into CAT-AAG-CG.

    2. Nitrogen Base Type Mutation

    Types of nitrogenous bases in DNA are divided into two groups, there are purines consisting of adenine and guanine (A and G), and pyrimidines consisting of cytosine and thymine (C and T).

    In nitrogenous base type mutations, the changes can occur in similar groups or are called transition substitution gene mutations. For example, adenine turns into guanine, or thymine turns into cytosine. If the change occurs in a different group, between purines and pyrimidines, the gene mutation is called a transversion substitution.

    Examples of Gene Mutations in Humans

    By now, you must have understood more about gene mutation, right? To be clear, you should also know examples of gene mutations in humans. Until now, gene mutations in humans have more adverse effects on the condition of the body, you know!

    One of the examples of gene mutations in humans can cause errors in the formation of red blood cells. Red blood cells that are initially round in shape turn into a sickle shape or commonly called sickle cell anemia .

    This sickle shape makes blood flow easily blocked so that less oxygen is carried by the blood, blood cells die quickly. The body of patients with sickle cell anemia is usually easily tired, dizzy, painful, has difficulty breathing, and can experience damage to several organs of the body.

    Another example of gene mutations in humans is cancer. Cancer occurs due to errors in the formation of amino acids that affect the cell division cycle.

    Cells in the body of cancer sufferers undergo mutations and divide continuously without stopping, until finally damaging the function of the sufferer’s organs. If that’s the case, gene mutations in humans can cause severe organ damage, or even make the sufferer die,

  • The Theory of Human Evolution and Its Controversy

    The Theory of Human Evolution and Its Controversy

    most of you must have heard stories about human origins, right? There is an evolutionary theory that says that humans came from apes. Do you think that information is correct or not? Well, before discussing this further, it’s a good idea to first know what is meant by the theory of evolution.

    Actually, until now there is still a debate about the theory of evolution. Instead of being curious, in this article, we wants to invite you to discuss what is meant by the theory of evolution, as well as unique facts and growing controversies. Read this article until it’s finished.

    What is the Theory of Evolution?

    The theory of evolution is a theory that discusses the changes or development of living things, their origins, and their genetic linkages between one living thing and another. In the theory of evolution, change or development of living things occurs due to a combination of three main processes, namely variation, reproduction, and natural selection.

    In the process of reproduction and variation, the characteristics or characteristics of a living being that form the basis of evolution are carried by genes and passed on to the next generation. The inheritance of this gene can be a lot of variation in a population.

    In short, when living things reproduce, their offspring will have new traits, it can be more common or rarer than the previous generation. These traits can occur due to gene mutations or gene transfer between populations or between species.

    The theory of evolution also states that evolution occurs due to the process of natural selection. In this natural selection, traits that are detrimental to living things will decrease, while traits that are beneficial will have a great chance of survival and reproduction. So, there will be more living beings in the next generation who will inherit these beneficial traits.

    In addition, adaptation is also an important factor in the evolutionary process of living things, you know. For example, in today’s humans, there are minor differences between people living on the coast and people living in the mountains.

    The number of red blood cells of people in the mountains is more than the red blood cells of people on the beach. This is an evolutionary process that occurs due to natural adaptations that occur in the human body.

    The culmination of the evolutionary process is usually marked by the emergence of new species. Based on history, it is the evolutionary process that has resulted in the emergence of many species of living things in this world.

    All living things have different species and these differences can be evidence that the theory of evolution really occurs in nature. Species differences can occur due to strict adaptation, geographical conditions of the region, gene mutations, and natural selection.

    Theory of Evolution According to Experts

    Some experts define the theory of evolution as follows:

    Anaximander

    It is argued that the origin of life on earth was the ocean. Therefore, all living things on earth, including humans, were originally fish.

    When the heat of the sun caused the appearance of land on earth, living things began to move to the land. According to him, it makes the evolution of living things from fish to various land living creatures, including humans.

    George Louis Leclerc

    Believe that the earth is very old, more than 7,000 years. Therefore, he argues that living things have existed and developed during the age of the earth based on their migratory movements.

    As a result of these migration movements, living things must eventually adapt to their new environment. The pattern of adaptation is what causes living things to evolve due to the interaction of organic particles that trigger changes in the bodies of living things.

    Jean-Baptiste Lamarck

    Has two ideas about evolution. The first idea relates to the parts of the body that are used and not used by living things.

    Through this idea, he assumed that the parts of the body that are constantly used by living things in dealing with certain environments will become bigger and stronger than the parts of the body that are rarely used. Meanwhile, limbs that are rarely used will experience setbacks.

    Lamarck’s second idea relates to the inheritance of traits or traits that living things acquire in adapting to their environment. It is this inheritance of traits or traits that modifies the organism that it acquires during its lifetime.

    For example, the so-called giraffe has a short neck, but because its neck is constantly sticking out to get leaves on a tall tree, the giraffe’s neck begins to get long. This long neck is passed on to all his descendants.

    Charles Robert Darwin

    argues that evolution occurs through the process of natural selection. Only living things that can adapt to nature can survive.

    In contrast to Lamarck who thought that giraffes were originally only short-necked, Darwin argued that the necks of giraffes were initially varied, some with short necks and some with long necks.

    Through the process of natural selection, the short-necked giraffe eventually became extinct and only the long-necked giraffe has managed to survive and reproduce to this day.

    In addition to explaining evolution based on the process of natural selection, Darwin also argued that all species on earth came from a common ancestor ( common ancestor ), which evolved over time.

    Early Human Evolution Theory

    By this point, you have begun to understand what is meant by the theory of evolution, right? To be clear, it’s better if you know the theory of early human evolution.

    After removing body hair, humans were naked for 1 million years. Why did they put on clothes later?

    As discussed earlier, Anaximander, a pre-Socratic philosopher who lived around 610–546 BC has discussed the possibility of how humans evolved from fish. However, there is no scientific evidence that can prove this opinion.

    Over time, this theory of human evolution focuses more on the assumption that humans evolved or evolved on earth from extinct primates, you know. The primates that are often associated with human evolution are ape-like primates. That’s why there is a lot of information circulating that humans came from apes.

    Evidence that primates are related to humans is from their genetics. DNA between humans and primates can reach a similarity of up to 97%. However, that does not mean that humans are considered to have originated from apes. This fact can only trace that humans and primates may have shared a common ancestor.

    Human Theory According to Charles Darwin

    In fact, information about humans evolving from apes emerged because of Charles Darwin’s theory of human evolution. In the book ” The Origin of Species ” which put forward the theory of evolution written by Charles Darwin, concluded that all living things came from a common ancestor ( common ancestor ) and are related to each other.

    According to Darwin in the book, the process of genetic mutation from a common ancestor resulted in the process of evolution and the emergence of various new species. Darwin imagined human evolution like a tree.

    A single tree trunk and roots are the ancestors of living things. While the twigs and leaves of trees become new species that were born due to the process of genetic mutation. The process of genetic mutation can occur due to natural selection in a long time.

    From natural selection, Darwin then divided the evolutionary process into microevolution and macroevolution. Microevolution is changes that occur in species in small ways. For example, changes in color or size in a population over several generations.

    While macroevolution is a change due to natural selection that is able to create new species. For example, the change of dinosaurs into birds, amphibian mammals into whales, and the ancestors of apes into humans.

    Human Evolution Theory Controversy

    Darwin’s statement about what is meant by the theory of human evolution that later caused controversy. Did humans come from apes or not?

    Actually, Darwin’s theory of humans never concluded with certainty that humans evolved directly from apes. He simply argued that all living things came from a common ancestor. Evidently, from the similarity of human DNA with primates by 97%.

    However, the theory of human evolution has already been debated. Essentialists and religious people reject this theory emphatically. They believe that humans have been created according to their shape and nature as they are now by God.

    Some people also think that Darwin’s theory cannot explain the missing link in the process of human evolution. The missing sequence of human evolution is a link between the hairy and tailed generation like apes and intelligent and intelligent living things like humans.

    The undiscovered human fossil in the form of half human and half ape is considered to be the missing link to explain the sequence of human evolution. The fossil is considered necessary to be valid evidence that humans did evolve from an ape.

    source: pahamify.com

    Even though the theory of evolution causes controversy, but you can see strong evidence about the truth of this theory of evolution. For example, you can see that the racial differences that exist in humans are part of the strict adaptation process that occurred in ancient homo sapiens . Or, you can see it from the immunity of bacteria and microbes to certain antibiotics that occurs due to the process of genetic change.

    That is a review of  the theory of human evolution, along with its controversies. Hopefully the above review can help you understand what is meant by the theory of evolution, yes.

  • Difference between Series and Parallel Circuits and Examples

    Difference between Series and Parallel Circuits and Examples

    Parallel circuit is one type of circuit or arrangement of electrical components that are connected in parallel.

    The parallel circuit formula is Voltage V= V1=V2=V3, resistance 1/R =1/R1 +1/R2 + 1/R3 and current flowing I = I1 +I2 + I3.


    In this modern era, electricity is a very important requirement for life. In fact, almost all human activities require a power source so that it is as if electricity is a cog in everyday life.

    However, many people still do not understand electricity, especially the basics of electricity such as series and parallel circuits.

    Knowledge of parallel series circuits is something that is commonly used by everyone. An example of its application is when someone wants to install a light installation in his house. Therefore, in this article, we will discuss series and parallel circuits starting from the differences, advantages and disadvantages along with examples of both.

    preliminary

    Before we dive deeper into series and parallel circuits, we need to know the basics first.

    An electrical circuit is a collection of several electrical components that are connected and attached to a voltage. Here are some electrical components along with symbols that are often used in circuits:

    There is also a symbol regarding another parameter called electric current. Usually, electric current is indicated by the direction of the arrow on the circuit and the symbol “I”

    Difference between Series and Parallel Circuits

    As we know, series and parallel circuits have significant differences. Some of these differences include:

    Differences in Circuit Arrangement

    What we can clearly see from the difference between the two circuits is the arrangement of the components installed. The arrangement can be seen from the branching of the cable or the placement of its components. For more details, here is the description in detail:

    Series Circuit

    “The series circuit has a simple arrangement so that the series arrangement does not have cable branches between the load or the installed voltage source.”

    Parallel circuit

    “In parallel circuits, there are complex arrangements and there are branching of cables between loads or installed voltages.”

    Circuit Component Difference

    Apart from the obvious differences in arrangement, we can distinguish series and parallel circuits from the components used. Although the amount of load or resistance can be adjusted, there are differences in the components, including:

    Series Circuit

    In a series circuit, the components are simpler consisting of a voltage source, cable and load. Although sometimes a series circuit uses a switch, a series circuit only requires one switch.

    Parallel circuit

    In parallel circuits, the components used tend to be more. An example is the cable that is used in parallel circuits is longer because parallel circuits have branches. In addition, parallel circuits usually use one switch for one load only.

    Differences in Physics Formulas and Parameters

    In addition to things that are clearly visible, there are other parameters that affect the series and parallel circuits, namely the electric voltage “V” and the electric current “I”. Of course to find these two parameters have different ways for series circuits and parallel circuits. Here’s how to calculate voltage and electric current in series and parallel circuits:

    Strong Electric Current

    Electric current is a quantity that states every electric charge that flows in a component. In series and parallel circuits, the electric current has a different calculation for each component.

    Series Circuit

    “The electric current in a series circuit has the same amount of electric current flowing through each resistance. This makes one point on the series circuit equal to another point.”

    Parallel circuit

    Also read:   Standard Deviation Formula (FULL) + Explanation and Example Questions

    “In a parallel circuit, the sum of the strong currents flowing out of the junctions will be equal to the sum of the strong currents entering the junctions.”

    Electrical voltage

    electrical circuits

    In an electric circuit, voltage is the amount of potential energy in an electric field and has units of volts. Electrical voltage in series and parallel circuits have different calculations.

    Series Circuit

    series circuit

    “In a series circuit, the electric voltage is not as strong as the current, but the voltage that is installed is equal to the voltages on the components.”

    Parallel circuit

    parallel circuit

    “Unlike the case with a series circuit, the voltage applied to all circuits will always be the same value in parallel circuits.”

    Electrical resistance

    In addition to voltage and current sources, there is one more parameter that is commonly owned by each component, namely resistance or load. On the total resistance of each circuit has a different way of addition including:

    Series Circuit

    series circuit

    “Every resistance that is connected in series in the circuit will add up to each other. So, the total resistance installed is the total resistance of each component.”

    Parallel circuit

    parallel circuit

    “While in a parallel circuit all the voltages on the components will be the same value. Therefore the total resistance installed in the parallel circuit as described in the picture above.

    Thus the article about series circuits and parallel circuits, hopefully it can be useful for you.

  • Types of Proximity Sensors

    Types of Proximity Sensors

    Proximity sensor is a detection tool that works based on the distance of the object to the sensor. The characteristic of this sensor is to detect objects at a fairly close distance. This proximity sensor has a working voltage between 10-30 Vdc and some use a voltage of 100-200VAC. Almost every production machine today uses this type of sensor, because in addition to being practical, this sensor includes a sensor that is resistant to impact or shock, besides that it is easy to carry out maintenance or replacement repairs.

    There are types of proximity sensors

    1. Inductive Proximity Sensor

    Inductive Proximity Sensor
    Inductive Proximity Sensor

    Inductive Proximity is used to detect metal objects. The working principle of inductive proximity is that if there is a voltage source, the oscillator in the proximity will generate a magnetic field with a high frequency. If a metal object is brought near the surface of the sensor, the magnetic field will change.

    Inductive Proximity Sensor
    Component of Inductive Proximity Sensor

    Changes in this oscillator will be detected by the sensor as a signal of the presence of an object. This example of Inductive Proximity is usually used in metal detectors at airports. This proximity sensor will detect the presence of metal objects even if they are not visible.

    2. Capacitive Proximity Sensor

    Capacitive Proximity Sensor
    Capacitive Proximity Sensor

    Capacitive Proximity sensor is   able to detect metallic and non-metallic objects. The working principle of capacitive proximity is by measuring the change in the electric field capacitance of a capacitor caused by an object approaching it. Capacitive proximity is usually used on car bumpers or other car parts. The simple benefit is to make it easier for the car to park, because this sensor will work when it detects objects at a certain distance so that the car will not hit the object.

    3. Optical Proximity Sensor

    Optical Proximity Sensor
    Optical Proximity Sensor (infrared)

    This sensor detects the presence of objects with light usually infrared. This optical proximity consists of a light and a receptor that detects an object by reflection. If an object is within a sensitive distance or an object hits the light from the sensor, the light will bounce back to the receiver and indicate that an object has been caught by the sensor.

    Optical Proximity Sensor
    Optical Proximity Sensor

    The disadvantages of this optical proximity sensor are that in its use sometimes the lens is dirty, the light is blurry, the reflection surface is poor and the object orientation is wrong. This optical proximity is usually used in touch screen cell phone technology. Because when receiving a call, the ear will become an object that blocks the emission of infrared rays, then the infrared rays will be reflected back and indicate that there is an object in front of them. The result is that the phone screen will be locked so that the screen does not random when it comes into contact with the ear.

  • 7 Types of Safety Hand Gloves

    7 Types of Safety Hand Gloves

    Maybe many of us are already familiar with safety hand gloves. Especially for those who work with a high potential for danger, the use of hand gloves is no longer just an obligation but a necessity so that our healthy and beautiful hands are not scratched and may even be seriously injured due to work.

    But did you know that there are  many types of safety gloves ?

    Safety hand gloves are tools used to protect hands from potential hazards such as scratches from sharp objects, heat, and even chemicals. Hand gloves that are used to protect from heat are certainly different from those used to protect hands from chemicals. What’s the difference? Then how to apply it? Here are some types of hand gloves based on their function and constituent materials:

     1. Impact Hand Gloves

    Impact Hand Gloves

    Hand Gloves of this type are hand gloves that are often used when machining, especially abrasives. The nitrile formulation in the material makes these gloves resistant to abrasion caused by friction. Cut & Puncture Resistant Glove is also resistant to sharp objects, so it is suitable for workers who use abrasive machines.

    3. Anti-Slip Hand Gloves

    Anti-Slip Hand Gloves
    Anti-Slip Hand Gloves

    Anti Slip Hand Gloves are used on wet or oily workpieces. These anti-slip gloves are equipped with Grip Technology so that oily or wet work objects can be gripped firmly without slipping. With microchannel technology, these gloves absorb liquid fluids that stick to the workpiece so that the contact of the glove with the workpiece is not blocked by these fluids.

    5. Lifting Hand Gloves

    Lifting Hand Gloves
    Lifting Hand Gloves

    This type of hand gloves is the type of safety gloves that are most often found on the market. Used to protect hands from scratches by sharp objects and minimize the potential for slippage when lifting something. These hand gloves are made of fibrous fabric. There are also several lifting hand gloves that are equipped with a rubber layer on the palm of the hand to increase hand grip strength when lifting.

    Do not use this type of hand gloves when you operate objects or rotating machines. Why? Because these hand gloves are made of fibrous cloth, there is the potential for the fibers to get caught in the rotating machine which actually endangers our hands.

    6. Heat Resistant Gloves 

    Heat Resistant Gloves 
    Heat Resistant Gloves

    These hand gloves are usually made of leather and have a smooth layer of cloth inside. These Heat Resistant Gloves are thicker and heavier than other hand gloves. Why is it made of rubber and thick? Because as the name implies, these hand gloves function as heat insulators that protect our hands from heat or high temperatures. In the market, these hand gloves are often referred to as welding gloves. Usually used when welding work, blander (cutting torch), and various other jobs that are directly related to high temperatures, furnaces, etc.

    In addition, there are also chemical gloves made of PVC. When viewed from the shape, these gloves usually have longer and thicker sleeves than other chemical resistant gloves. Chemical Resistant Gloves of this type are commonly used during painting jobs.

    Chemical Resistant Gloves

    Of course, there are many other types of safety hand gloves. Hopefully this article can provide more knowledge for those of you who are going to buy safety gloves. The more suitable the gloves are, the smaller the potential danger.

  • 12 Types of Screws and Bolts

    12 Types of Screws and Bolts

    The type of fixing screw ( Set Screw ) commonly known as the cap screw has a shape similar to a bolt, but this type of screw is full-grained. The difference between a bolt and a screw is that the bolt has a thread that is not complete, in other words the thread does not reach the head of the bolt.

    While the screw has a thorough thread until it reaches the screw head. Another difference can also be identified from the bolt and screw heads. In its use, the bolt does not use a screwdriver but a key, while the screw uses a driver,  in the form of a screwdriver .

    Here are the types of set screws and their bolts:

    1. Fastener Screw (Set Screw)

  • Emergency Response Plan Planning to Face Potential Disasters

    Emergency Response Plan Planning to Face Potential Disasters

    Emergency Response Plan Planning to Face Potential Disasters – In this very dynamic world, apart from the challenges of globalization and business competition, industry players and society are also faced with unavoidable potentials, namely the potential for disasters. Disasters in this case include fires, riots, earthquakes, floods, tsunamis, volcanoes, and other things. In Indonesia, which is an archipelagic country, most of the land is located in an active tectonic plate line, which is known as the Ring of Fire. This shows that islands that cross this line, namely the islands of Java, Sumatra, Bali, and Papua are at risk of experiencing a higher frequency of earthquakes due to tectonic shifts, as well as the potential for active volcanoes.

    Because natural disasters generally occur suddenly and cannot be avoided, therefore the company management needs to prepare a risk assessment and concrete planning to deal with disasters. For this reason, an emergency response planning management system needs to be carefully prepared by the company as an emergency response to a disaster that occurs.

    Emergency Response Plan (ERP) is defined as an Emergency Response Plan, which is a plan document that contains the necessary procedures to be carried out in the event of an emergency. So in the plan, there are instructions and complex solutions regarding all actions and prevention in emergency situations experienced by the company, workers, employees, and the surroundings.

    Why is Emergency Response Plan important?

    The Emergency Response Plan acts as the first response action that needs to be taken in responding to and dealing with an incident. Some of the processes contained in this ERP are designed to be implemented in the early minutes of an emergency. In making ERP, companies generally carry out a risk assessment followed by determining various possible emergency scenarios, where in every emergency situation they must have a first action / response plan specifically designed to mitigate and minimize risk.

    Through a good Emergency Response Plan system, all parties related to the company/employer can experience several benefits, including:

    1. Raise awareness of the importance of preparedness in dealing with various emergencies
    2. Facilitate hazard control, evacuation process, and help respond to potential hazards that occur within the company
    3. Useful for preparing to reduce the various impacts that occur as a result of a disaster
    4. Able to coordinate what efforts will be made so that it goes well and correctly
    5. Help reduce the cost of losses from a disaster or emergency in a company
    6. Assist as input (feedback) on the development of existing ERP systems sistem

    Important Aspects in Emergency Response Plan Planning

    The Emergency Response Plan (ERP) must be made in such a way as to be able to handle emergencies, especially in the workplace. For this reason, in this article, We will discuss important aspects that need to be considered in making an Emergency Response Plan based on OSHA regulations:

    ERP planning must be made in writing, stored in the workplace both hardcopy and softcopy so that it can be accessed by all employees. Companies with less than 10 employees can communicate ERP verbally.

    ERP planning should include:

    1. Procedures for reporting fires or other emergencies
    2. Procedures for emergency evacuation, including the type of evacuation and the determination of exit routes
      using floor plans or workplace maps that clearly indicate emergency exits
    3. Color coded as an exit route guide, in order to assist employees in determining the nearest exit route
    4. Procedures that must be followed by employees regarding machines or other equipment in the workplace or factory that are important to be turned off before the evacuation process
    5. Provision of backup power supplies, power plants such as generator sets , availability of water supplies, and other essential services for emergency situations
    6. Procedures to account for all business processes and employee safety after the evacuation process
    7. Procedures to be followed by rescue workers as well as medical personnel
    8. Ensure the availability of information regarding the name or position of the PIC that can be contacted by employees who need more information about ERP to find out the tasks / actions required
    9. Maintenance of the alarm system as the main notification device for employees in emergency situations
    10. Provision of training and appointment of PICs to help the evacuation process run smoothly, safely and in an orderly manner
    11. Ensure a sufficient number of employees to act as evacuation assistants in times of emergency
    12. One evacuation assistant employee for every 20 other employees is considered sufficient
    13. The company/employer is responsible for adequate employee involvement and knowledge regarding the evacuation process, which includes knowledge of facility layout, exit routes, nearest shelter (both indoor and outdoor), and awareness of employees who may be in need of additional assistance
    14. Regularly review and update ERP, especially for facilities that are undergoing renovations or other changes to building structures

    In planning the making of an Emergency Response Plan, the company / employer can also discuss or consult with ERP experts, as well as with the related building management to ensure procedures for disaster scenarios, both in terms of actions, availability of safety tools and equipment , emergency exit routes, and others. This aims to provide the maximum possible convenience and security for all workers, as well as carry out a risk assessment to minimize other impacts that may arise.

  • Product Differentiation: Definition, Strategy & Impact for Business

    Product Differentiation: Definition, Strategy & Impact for Business

    What is product differentiation?

    Product differentiation is the process that differentiates your product or service from others. This process involves detailing the characteristics of each product that consumers value and making it unique. When successful, product differentiation creates a competitive advantage because customers see your product as superior.

    Why is product differentiation important?

    It is important for a company to be different from its competitors, as hundreds of new products enter the market every day. When faced with too many choices, consumers will be confused in choosing and ultimately make the decision not to buy. That’s why it’s so important for your business to find ways to make your product stand out and be perceived as unique and valuable over similar items.

    The marketing team will try to explain to all customers what advantages your product offers and compare it to competitors. If your company has many products, make sure each product has a clear identity to avoid confusion when consumers make choices. Creating a different product is something that appeals to potential customers. This can help build a product’s competitive advantage over other brands.

    Product Differentiation Strategy

    A good product differentiation strategy can earn brand loyalty, the most important thing for any successful business. This strategy focuses on the buyer’s perception of value. As long as the seller continues to provide the highest quality of service, the customer base will remain loyal.

    Market segmentation is currently faced with very competitive business competition. If a product is not consistently high quality, consumers will turn to other options. Creating a unique product will not be enough to gain a competitive advantage from product differentiation if buyers don’t know how your product differs from other brands.

    The seller must have a thorough understanding of the buyer’s expectations and how the product will be used. For example, the purpose of buying a car is for transportation, but if buying the car will also give you a feeling of accomplishment and high self-esteem, then the seller will have a competitive advantage over the car he is selling.

    Another very important way of product differentiation is to contribute to the buyer’s perception that there is no brand that is similar to the product we market. Product differentiation will highlight the things that distinguish our products from competitors. Consumers will see that competitors’ products cannot meet their needs. This increases consumers’ expectations about the quality standards they will be aware of.

    What are the key features that differentiate Apple’s products?

    The company’s products have always been designed to be ahead of peers. Despite high competition, Apple has succeeded in creating demand for its products. As a result, the company has power over prices through product differentiation, innovative advertising, ensured brand loyalty, and hype around new product launches

    Ways to Differentiate Your Products

    You don’t want your product to look weird just because you want it to look different, do you? Instead, consider what is most important to your customers and let that drive your decisions about how to differentiate your product. Your product differentiation should emerge after carefully researching the competition and it should be part of your larger product vision.

    1. Benefits

    What value can customers get when using your product compared to competitors’ products? What problems will your product solve? How will it make prospecting easier and better? For example, your product may be the only mobile app that can know the weather in a certain area in real-time. This kind of thing is really needed for those field workers.

    2. Design

    Does your product have a distinct design and set it apart from the rest? For example, say your product is sleek and has a simple user experience, while your competitors’ offerings seem dated and outdated. This distinction can help customers connect with your brand. An example is the modern design sensibility of the Nest brand thermostat . Instead of copying rectangular shapes on other thermostats, the company opted for simple circles with easy-to-read, color-changing displays.

    3. Price

    Are the prices of your products lower or higher than those of your competitors and other products you offer? Your price should reflect the overall value of the value and features you offer. For example, you can justify a higher price if customers know that your product offers best-in-class quality. This is what the car company Ferrari does, which sets a fairly high price for each of their output cars. On the other hand, pricing your product too low can lead customers to think that your product is not the best choice.

    4. Quality

    Does your product work or be of better quality than your competitors’ products? Do you offer some functionality that your competitors don’t have? Can users or consumers expect the product to last longer than other products? Your product’s competitive advantage may indeed prove to be a superior and reliable construction.

    5. Customer service

    Your product features may be similar to others in many ways. However, you can differentiate your product through your product experience by putting together a professional customer service team to earn a reputation for being responsive to customer needs, requests and ideas. Aftersales in business is very important. You need to know, maintaining consumer loyalty to your product is more difficult than just getting new customers.

    Conclusion

    Ultimately, how you differentiate your product should not be an arbitrary decision or a reactive response to whatever your competitors are doing. Instead, your product differentiation should emerge from a strategy of high-level goals and initiatives specific to your product and your business.

    Along with that, using the right tools for your business is another thing that can make your business grow optimally. For example tools for recording transactions and accounting. In the current era of information speed, choosing an accounting application that can be used anytime and anywhere is a must for those of you who want to develop a business.

  • Energy Revolution, Transition to Renewable Energy

    Energy Revolution, Transition to Renewable Energy

    Renewable energy is not the only effective approach to reducing carbon emissions. Renewable Energy will continue to play a growing role in power generation capacity, he said, but it is projected that by 2050, 74% of global primary energy demand will still be supplied by coal, oil and gas.

    Instead, industry leaders and energy experts recognize there are many different avenues to explore on the journey towards delivering cleaner energy. Now that the energy sector understands this premise, realistically, achieving a low-carbon future becomes a more complex challenge.

    Mitigating climate change while balancing the growing global demand for energy remains a key focus for the industry, but there are many other considerations. Key challenges for the years ahead include addressing supply intermittency, navigating economic realities and ensuring a safe and consistent energy supply.

    Natural gas remains the main focus of the transition to cleaner and more fuel-efficient fuels, supported by several factors: including falling renewable energy prices; the growing impact of innovations such as carbon capture and provision (CCS); alternative fuels for coal and oil; and expansion of wind and solar technology.

    Costly moving towards cleaner energy, solar power, along with offshore and onshore wind generation, holds the key to the renewable resources of the future. The success of this emission-free technology is driven by cost reductions, coupled with increased generating capacity. As future energy generation leans towards a decentralized power grid, matching supply with demand will prove a challenge. New innovations or alternative fuels will be needed to combat the intermittency of renewable energy supplies to generate power when there is no sunlight or wind.

    The large number of new energy solutions being brought to market creates a large trader risk for the energy industry. The danger of investing in the wrong technology, or in solutions that cannot be measured, acts as a barrier to new innovations being adopted.

    Future Energy Sector

    Natural gas remains the main focus of the transition to renewable energy, but also has an important role in the long-term energy mix, along with other alternative fuels such as hydrogen and biomass. These fuels support renewable energy in an effort to meet the growing demand in the energy sector of the future.

    Biomass is a cleaner source of fuel that does not require large investments in infrastructure, as the process of generating electricity is the same as using fossil fuels.

    Improve Energy Efficiency

    In addition to reducing emissions by using alternative fuels, the energy sector is also developing ways to increase energy efficiency and reduce the environmental impact of traditional fossil fuels.

    Another efficiency-enhancing technology, which can be applied to the manufacture of things like cement, steel, glass and metal, is waste heat recovery. That in heat recovery applications, organic rankine cycle (ORC) units increase the efficiency of the production process by converting low-level heat into useful power.

    model world

    In an increasingly digital world, the Fourth Industrial Revolution is poised to transform the energy sector, just like most other industries.

    Advances in Artificial intelligence (AI), The internet of things ( IoT) and machine learning will automate processes, optimize efficiency and lower costs. In a rapidly changing world, digital energy generation and distribution will enable the energy sector to model real-world behavior and simulate the resource and infrastructure challenges required to scale renewable energy in the future. Using technology to make decisions and create realistic models should make the simulations as realistic as possible.

    Framework for success

    To meet the uncertain challenges of the future energy sector, there is a growing industry confidence in market-based solutions involving government and private sector alliances. By working in unison, policymakers and industry representatives can create a flexible regulatory framework to facilitate the transition to renewable energy.

    Government support and encouragement gives the energy sector scope to absorb and scale up new technologies. The increasing global demand for energy will put pressure on the market in the future as renewable energy becomes fully utilized. In the future, long-term seasonal generation reserves will be very important, including from fossil fuels.

  • Edge Computing Technology

    Edge Computing Technology

    Methods for storing and leveraging data are constantly evolving, which is why it’s critical for tech businesses to follow them to ensure they are implementing best practices. Edge computing will enable businesses to do just that by enabling them to process data near the edge of their IT network, offering accelerated data streaming and instant communication.

    What is Edge Computing?

    Edge Computing basically refers to the process of data being collected, stored and analyzed at the ‘edge’ of the network where the original data is generated. In contrast to cloud-based methods of data being collected, stored and analyzed on servers or centralized data centers. While edge computing is not a commonly used phrase today, it will become a central part of the technology landscape over the next few years. This is the result of a large amount of data being processed, largely through the increased use of Internet of Things (IoT) devices, of which there will be over 50 billion in use by 2020. As a result, there is an increasing need for more computing power and data storage. the more;

    These data centers will bear little physical resemblance to the large, centralized data centers we see in a typical corporate environment. They will have the ability to be managed and automated remotely, as they are likely to be on a site with little, or no IT personnel.

    Align advanced computing with your digital transformation strategy

    First, you need to see Edge Computing as a central part of your digital transformation strategy, as it will have a significant impact on the development of new revenue streams, products and services. Second, there needs to be an appreciation of the speed of development, because the construction of edge data centers needs to be completed quickly to meet business requirements. In terms of delivery, third-party integration is a potential solution, as vendors who have traditionally delivered a converged infrastructure, which brings together servers, networks, storage, and software in a single solution, are now doing the same with the data center edge.

    The skills your business needs

    It is important to strategically recruit for Edge Computing related positions to get the right infrastructure for your organization. In terms of skill sets in the Edge Computing space, you need to find candidates with the following skills:

    • Powerful data center and cloud experience
    • Exposure to security, storage, networking, and virtualization

    Implementation of Edge computing will not be an easy ‘plug-and-play’ solution, and as such, you need to assess the inevitable changes to your existing IT architecture. This means that you need to hire senior specialists who have an understanding of excellence throughout the design, implementation and support stages.

    Take advantage of the benefits

    As with any new trend in the technology space, the recruitment industry will be best positioned to serve its clients by understanding the skill set that needs to be supplied, to meet the inevitable demand brought about by the rise in Edge Computing. Having a detailed understanding of a client’s strategy in Edge Computing as part of their digital transformation roadmap will be key, not only enabling the delivery of the right skill set, but also enabling this skill set to be delivered in the correct time frame.

    Edge Computing vs cloud computing

    Edge computing will not replace cloud computing as cloud computing will continue to be an important part of the IT landscape in the same way as on premise computing. Instead, Edge Computing and the cloud will coexist.

    Businesses that can find the best way for edge and cloud to complement each other will have the greatest success from their computer services. In an ideal setting, cloud computing would continue to take responsibility for larger functions such as big data analytics, large-scale data storage, and business logic, while Edge Computing would allow on-premises devices to run as effectively as possible without constant intervention from the cloud. wider.

    Key benefits of Edge Computing

    1. Speed

    Edge Computing allows devices to respond instantly, sometimes in microseconds, as it cuts out the need for data going back and forth between centralized servers.

    2. User experience

    In addition to speed, the overall experience for end users will be improved through high latency and unreliable connections, such as those in remote locations.

    3. Security and privacy

    Tighter security and privacy around sensitive data would mean that, theoretically, you would be able to avoid sending sensitive data off-site, and instead process this data locally.

    4. Reliability

    With edge data centers located closer to the end user, there are far less chances of network problems in offsite locations impacting on-premises customers. Even in the event of a critical issue, such as a data center outage, IoT devices connected to the localized edge network must continue to operate independently.

    5. Save cost

    Edge Computing must provide a level of cost savings for your business. Given that it will allow a significant reduction in data flow load on a centralized server, thereby saving network and computing resources, leading to reduced congestion on the network, and less energy demand for servers.

    Why edge computing is important

    Edge Computing is not going to be a passing trend. This is because it is a central part of the business technology landscape, as is cloud computing. According to International Data Corporation (IDC) Worldwide IoT 2018 predictions: “By 2020, IT spending on advanced infrastructure will account for up to 18% of total spending on IoT infrastructure.” In the immediate short term, it will be the organizations that have the most effective transformation strategies around Edge Computing and IoT that will be rewarded ahead of their competitors.
