Banten's Air Pollution in the Morning (25/10) is the Worst in Indonesia

Air quality in Banten this morning is the worst in Indonesia. Based on the Air Pollution Standard Index (APSI) page of the Ministry of Environment and Forestry (KLHK) on Saturday (25/10/2025) at 08:00 AM WIB, it was revealed that Banten's air quality index was 95.

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

APSI calculation is based on the measurement results of seven air pollutant parameters, namely PM10, PM2.5, NO2, SO2, CO, O3, and HC. The measurement of air pollutant parameters is spread across 72 stations in various regions.

Based on KLHK Regulation No. 14 of 2020 concerning the Air Pollution Standard Index, an APSI in the range of 0-50 indicates good air quality, a range of 51-100 means moderate air quality, and a range of 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 more than 300 can seriously harm health and requires quick handling.

Below Banten, South Sumatra ranks second worst in Indonesia with an air quality index of 90. Then, in third place is Jambi with an air quality index of 89.
