DKI Jakarta's Morning Air Pollution (Dec 4) is the Worst in Indonesia

Air quality in DKI Jakarta this morning is the worst in Indonesia. Based on the Air Pollutant Standard Index (ISPU) page of the Ministry of Environment and Forestry (KLHK) on Thursday (Dec 4, 2025) at 08:00 AM WIB, it was revealed that the air quality index in DKI Jakarta was 113.

According to the KLHK Directorate of Air Pollution Control, 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. Air pollutant parameter measurements are distributed across 72 stations in various regions.

Based on KLHK Regulation No. 14 of 2020 concerning the Air Pollutant 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 harmful 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 prompt action.

Below DKI Jakarta, Banten ranked second worst in Indonesia with an air quality index of 102. Then, in third place was South Sumatra with an air quality index of 98.

This means no region has hazardous air quality.
