South Sumatra's Air Quality on Friday Night (March 6) is the Worst in Indonesia

South Sumatra's air quality 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 (March 6, 2026) at 6:00 PM WIB, it was revealed that the air quality index in South Sumatra is 99.

According to the KLHK Air Pollution Control Directorate, ISPU is a unitless number used to describe the ambient air quality condition at a specific location and is based on impacts on human health, aesthetic value, and other living beings.

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 Pollution Standard Index, ISPU in the 0-50 range indicates good air quality, 51-100 means moderate air quality, and 101-200 indicates unhealthy air that is harmful to humans, animals, and plants.

Next, very unhealthy air in the 201-300 range can increase health risks for sensitive groups. Meanwhile, hazardous air quality in the range above 300 can seriously harm health and requires immediate handling.

Below South Sumatra, Jambi ranks second worst in Indonesia with an air quality index of 96. Then, Riau is third with an air quality index of 93.

This means no region has hazardous air quality.
