Riau's Air Quality on Thursday Morning (8/1) Worst in Indonesia

Air quality in Riau 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 (1/8/2026) at 08.00 WIB, it was revealed that the air quality index in Riau was 97.

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 and is based on impacts on human health, aesthetic value, and other living organisms.

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

Next, 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 rapid handling.

Below Riau, Aceh occupies the second worst position in Indonesia with an air quality index of 96. Then, in third position is Banten with an air quality index of 95.

This means that no region has hazardous air quality.
