South Jakarta’s Air Quality Using PM 2.5 Data at the Beginning of COVID-19 Restriction

As soon as the lockdown was established in Jakarta, Indonesia, people experienced a change in Jakarta’s air quality. This research was conducted to answer several challenges such as: where to find Indonesia’s air quality open data platforms, how to handle the acquired data with SQL technology, and how to validate whether the air quality of Jakarta was significantly changed from a period to another or not. With particulate matter 2.5 (PM 2.5) data acquired by The United States Diplomatic Post in South Jakarta, a data visualization was generated to describe the fluctuation of PM 2.5 from February 29th to June 29th. By conducting a two-sample t-test, a significant change in South Jakarta’s air quality was revealed. The test concluded that South Jakarta’s air quality got worse even after a lockdown was established.
