West Java is the Most Polluted in Indonesia This Morning (March 19)

West Java has the worst air quality in Indonesia this morning. Based on the Air Pollution Standard Index (ISPU) page of the Ministry of Environment and Forestry (KLHK) on Thursday (March 19, 2026) at 08:00 WIB, it was revealed that West Java's air quality index is 137.

According to KLHK's Air Pollution Control Directorate, ISPU is a unitless number used to describe ambient air quality conditions at a specific location, based on impacts on human health, aesthetic value, and other living beings.

ISPU calculations are based on measurements of seven air pollutant parameters: PM10, PM2.5, NO2, SO2, CO, O3, and HC. 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, an ISPU range of 0-50 means good air quality, 51-100 means moderate air quality, and 101-200 means unhealthy air that is harmful to humans, animals, and plants.

Next, an ISPU range of 201-300 indicates very unhealthy air that can increase health risks for sensitive groups. Meanwhile, an ISPU above 300 means hazardous air quality that can seriously harm health and requires immediate handling.

Following West Java, Riau ranks second with the worst air quality in Indonesia with an index of 96. Then, South Sumatra is in third place with an air quality index of 94.
