Project description:

Restrictions on residents’ activities during the Covid-19 are believed to reduced air pollution over the city of Jakarta. However, air quality index data reveals the opposite fact that pollution still surrounds the capital city. 

In fact, some residents still believe that Jakarta’s air is not completely bad. This is evident from the results of a survey conducted by the Katadata Insight Center (KIC) in August 2021.

We also summarize a number of “myths” that some of the residents believe. As a comparison, we used data collected by Nafas, a startup provider of air quality measurement applications.


Impact reached:

The poor air quality in Jakarta and its surrounding areas should be a lesson that air pollution is the enemy of all of us. Because, this can have an impact on health in the future.

Residents of the capital city needs to encourage the government to immediately deal with sources of pollution in the capital city. For example, by conducting emission tests for cars, factories, and so on.

Techniques/technologies used:

We interviewed the governments, the observers, and the startup who provides air quality measurement. We use Flourish and Microsoft Excel to calculate and analyze the data that we collect.

What was the hardest part of this project?

Gather all the informations we need and analyze our findings based on the data.

What can others learn from this project?

The importance of data to strengthen the argument in our article. In this case, is about how bad the air quality is in Jakarta, Indonesia.
