South Sumatra's Air Quality on Thursday Morning (1/1) Worst in Indonesia

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 (1/1/2026) at 08:00 AM WIB, it was revealed that the air quality index in South Sumatra was 102.

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

ISPU calculations are based on measurements of seven air pollutant parameters: PM10, PM2.5, NO2, SO2, CO, O3, and HC. Air pollutant parameter measurements are spread across 72 stations in various regions.

Based on KLHK 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 means moderate air quality, and 101-200 means 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 over 300 can cause serious health damage and requires quick handling.

Below South Sumatra, Riau ranks second worst in Indonesia with an air quality index of 101. Then, in third place is Aceh with an air quality index of 96.

This means that no region has hazardous air quality.
