Friday Morning Air Pollution (23/1): West Java Worst, How About Other Regions?

Air quality in West Java 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 Friday (January 23, 2026) at 08:00 AM WIB, it was revealed that the air quality index in West Java was 741.

According to the KLHK Directorate of Air Pollution Control, 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 calculation is based on the measurement results 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 KLHK Regulation No. 14 of 2020 concerning the Air Pollution Standard Index, ISPU in the range 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 201-300 can increase health risks for sensitive groups. Meanwhile, hazardous air quality in the range above 300 can seriously harm health and requires quick action.

Below West Java, DKI Jakarta ranks second worst in Indonesia with an air quality index of 147. Then, in third place is South Sumatra with an air quality index of 100.

This means West Java has hazardous air quality.

Here is a list of the 10 provinces with the worst air quality index in Indonesia on Friday, January 23, 2026, at 08:00 AM WIB.
