Banten Most Polluted in Indonesia This Morning (9/11)

Banten's air quality 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 Sunday (9/11/2025) at 08.00 WIB, it was revealed that Banten's air quality index was 95.

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

ISPU calculations are based on the measurement results of seven air pollutant parameters, namely PM10, PM2.5, NO2, SO2, CO, O3, and HC. Measurements of air pollutant parameters are spread 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, the range 51-100 means moderate air quality, and the range 101-200 indicates unhealthy air quality that is detrimental to humans, animals, and plants.

Furthermore, 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 handling.

Below Banten, West Java ranks second worst in Indonesia with an air quality index of 90. Then, in third place is South Sumatra with an air quality index of 88.

This means that no region has hazardous air quality.
