Banten Air Quality Thursday Morning (9/10) Worst in Indonesia

Air quality in Banten 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 Thursday (9/10/2025) at 08:00 AM WIB, Banten's air quality index was 104.

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

ISPU calculations are based on the measurement results of seven air pollutant parameters: PM10, PM2.5, NO2, SO2, CO, O3, and HC. Measurements of these air pollutant parameters are spread across 72 stations in various regions.

Based on KLHK Regulation No. 14 of 2020 concerning the Air Pollution Standard Index, an ISPU in the range of 0-50 indicates good air quality, 51-100 indicates moderate air quality, and 101-200 indicates unhealthy air quality that is detrimental to humans, animals, and plants.

Furthermore, 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 prompt action.

Below Banten, East Java ranks second worst in Indonesia with an air quality index of 99. Then, in third place is DKI Jakarta with an air quality index of 96.

This means that no region has hazardous air quality.
