摘要：Clean air is a basic thing that is needed by living things. This makes clean air is very important for the continuity of life. Therefore, an air pollution standard index is needed to determine air quality based on the concentration of gas contained in it. As the State Capital which is the center of the economy, DKI Jakarta Province has an important air quality issue that needs to be controlled regularly. This research is a qualitative descriptive study of secondary data on the air pollutant standard index to compare the gas concentration parameters in the air before and during the COVID19 pandemic. The results of the analysis show that during the COVID-19 pandemic there was an increase in the “good and moderate” category days and a decrease in the “unhealthy and very unhealthy” category days compared to before the COVID-19 pandemic.
