Air quality in Banten tonight is the worst in Indonesia. Based on the Air Pollution Standard Index (ISPU) page of the Ministry of Environment and Forestry (KLHK) on Friday (January 16, 2026) at 18:00 WIB, it was revealed that the air quality index in Banten was 95.

According to the Directorate of Air Pollution Control of KLHK, ISPU is a unitless number used to describe 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 air pollutant parameters are spread across 72 stations in various regions.

Based on Ministry of Environment and Forestry Regulation No. 14 of 2020 concerning the Air Pollution Standard Index, an ISPU 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.
