D. An example of how to determine the main idea in a paragraph

After understanding the meaning, characteristics and five ways to determine the main idea in a paragraph. The following will present an example to determine the main idea in a paragraph, including:

Please pay attention to the following paragraphs:

People who are about to retire need not stress. Retirement means not working, but getting a salary. Being out of service means they have less to worry about at work and more free time for leisure. If free time can be optimized with positive and productive activities, then people will not be stressed.

In this paragraph, the main idea is in the first sentence. The main idea of ​​the paragraph above is “No need to stress when facing retirement”.

Based on the analysis that has been done on other sentences. In addition to the first sentence or the second sentence and so on basically has a function as an explanatory sentence for the main sentence (first sentence). This can be seen in the following example, namely in the sentence, “Being out of service means they don’t have to worry about work and have lots of free time to relax.” This sentence has the role of referring to the main sentence or can be said to provide “reasons” regarding the question “Why do people who retire do not need to stress.”

Now, after you can understand the analysis example above, here is another example.

The mud flood disaster caused by the collapse of the Situ Gintung embankment in South Tangerang has caused various diseases. Some of the diseases that will arise after the disaster are diarrhea, typhus, leptospirosis and dengue fever. Health problems for victims and the community around the disaster site must be anticipated immediately. Some of these diseases arise because the environment is dirty and clean water sources are polluted by mud.

This paragraph basically has the main idea in its first sentence, namely “The mud flood disaster caused by the collapse of the Situ Gintung embankment in South Tangerang caused various kinds of diseases”.

If you have read carefully and thoroughly the paragraph, you can definitely see that the second sentence and so on only have a function to explain and describe the disease from the mud flood disaster. The next sentence presents more specific information, so it doesn’t show a sign as the main idea. For example, in the second sentence of the paragraph contains an example of the disease caused. In addition, the last sentence in the paragraph also explains the causes of the emergence of the disease, does not explain the causes in general.

Every day there are sections of the road that are repaired, then half of the roads are closed. As a result, traffic jams and long lines. For those who go with high punctuality, don’t expect to be on time.
