Air Pollution Tuesday Night (7/10): Banten is the Worst, How About Other Regions?

Air quality in Banten tonight is the worst in Indonesia. Based on the Air Pollutant Standard Index (APSI) page of the Ministry of Environment and Forestry (KLHK) on Tuesday (7/10/2025) at 6:00 PM WIB, it was revealed that the air quality index in Banten was 96.

According to the KLHK Directorate of Air Pollution Control, APSI 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.

APSI calculation is based on the measurement results of seven air pollutant parameters: 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, an APSI 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.

Next, 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 quick handling.

Below Banten, South Sumatra ranks second worst in Indonesia with an air quality index of 94. Then, in third place is Jambi with an air quality index of 93.

This means no region has hazardous air quality.
