Air Pollution Wednesday Morning (3/12): DKI Jakarta is the Worst, How About Other Regions?

Air quality in DKI Jakarta this morning is the worst in Indonesia. Based on the Air Pollution Standard Index (ISPU) page of the Ministry of Environment and Forestry (KLHK) on Wednesday (3/12/2025) at 08:00 AM WIB, it was revealed that the air quality index in DKI Jakarta was 109.

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

ISPU calculations are based on the measurement results of seven air pollutant parameters: PM10, PM2.5, NO2, SO2, CO, O3, and HC. Measurements of air pollutant parameters are spread across 72 stations in various regions.

Based on the Minister of Environment and Forestry Regulation No. 14 of 2020 concerning the Air Pollution Standard Index, an 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.

Next, 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 more than 300 can seriously harm health and requires quick handling.

Below DKI Jakarta, Riau ranks second worst in Indonesia with an air quality index of 100. Then, in third place is West Java with an air quality index of 99.

This means no region has hazardous air quality.

Here is a list of the 10 provinces with the worst air quality index in Indonesia on Wednesday, December 3, 2025, at 08:00 AM WIB.
