Jakarta's Air Pollution Worst in Indonesia on the Morning of April 6th

Air quality in DKI Jakarta this morning is the worst in Indonesia. According to the Ministry of Environment and Forestry (KLHK)'s Air Pollutant Standard Index (ISPU) page on Sunday (6/4/2025) at 08.00 WIB, the air quality index in DKI Jakarta is 88.

According to the KLHK's Directorate of Air Pollution Control, ISPU is a unitless number used to describe the ambient air quality condition in a specific location, based on its impact on human health, aesthetics, and other living beings.

The ISPU calculation is based on measurements of seven air pollutant parameters: PM10, PM2.5, NO2, SO2, CO, O3, and HC. Air pollutant parameter measurements are spread across 72 stations in various regions.

Based on the Minister of Environment and Forestry Regulation No. 14 of 2020 concerning the Air Pollutant Standard Index, an ISPU in the range of 0-50 indicates good air quality, 51-100 indicates moderate air quality, and 101-200 indicates unhealthy air quality that is harmful to humans, animals, and plants.

Next, very unhealthy air quality in the range of 201-300 can increase health risks in sensitive groups. Meanwhile, hazardous air quality in the range of over 300 can seriously harm health and requires immediate action.

Below DKI Jakarta, Banten is ranked second worst in Indonesia with an air quality index of 86. Then, in third place is Riau with an air quality index of 79.

This means that no region has hazardous air quality.
