DKI Jakarta's Air Quality This Morning (28/1) is the Worst in Indonesia

The 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 (28/1/2026) at 08:00 AM WIB, it was revealed that the air quality index in DKI Jakarta was 147.

According to the Directorate of Air Pollution Control of KLHK, ISPU is a unitless number used to describe the ambient air quality conditions at a certain 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: PM10, PM2.5, NO2, SO2, CO, O3, and HC. Measurements of these air pollutant parameters are spread across 72 stations in various regions.

Based on Ministerial Regulation of KLHK 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.

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

Below DKI Jakarta, South Sumatra ranks as the second worst in Indonesia with an air quality index of 101. West Kalimantan follows in third place with an air quality index of 97.
