DKI Jakarta's Air Quality on Monday Night (6/10) is the Worst in Indonesia

Air quality in DKI Jakarta tonight is the worst in Indonesia. Based on the Air Pollution Standard Index (ISPU) page of the Ministry of Environment and Forestry (KLHK) on Monday (6/10/2025) at 18.00 WIB, it was revealed that the air quality index in DKI Jakarta was 100.

According to the Directorate of Air Pollution Control of KLHK, ISPU is a dimensionless number used to describe the ambient air quality conditions at a specific location, based on its impact on human health, aesthetic value, and other living things.

ISPU calculation is based on the measurement results of seven air pollutant parameters, namely PM10, PM2.5, NO2, SO2, CO, O3, and HC. The air pollutant parameter measurements are distributed across 72 stations in various regions.

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

Furthermore, very unhealthy air quality in the range of 201-300 can increase health risks for sensitive groups. Meanwhile, hazardous air quality in the range of over 300 can seriously harm health and requires rapid intervention.

Below DKI Jakarta, West Java ranks second worst in Indonesia with an air quality index of 97. Then, in third place is Jambi with an air quality index of 95.
