Air quality in South Sumatra 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 Thursday (January 22, 2026) at 08:00 AM WIB, it was revealed that the air quality index in South Sumatra was 100.
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, namely PM10, PM2.5, NO2, SO2, CO, O3, and HC. Air pollutant parameter measurements are spread across 72 stations in various regions.

Based on Ministry of Environment and Forestry Regulation No. 14 of 2020 concerning the Air Pollutant 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 harmful to humans, animals, and plants.
Furthermore, very unhealthy air quality in the 201-300 range 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 action.
Below South Sumatra, North Sumatra ranks second worst in Indonesia with an air quality index of 98. Then, in third place is Banten with an air quality index of 95.
This means no region has hazardous air quality.
