Riau's Air Quality Worst in Indonesia on Saturday Morning (February 22nd)

Air quality in Riau this morning is the worst in Indonesia. According to the Ministry of Environment and Forestry (KLHK)'s Air Pollutant Standard Index (ISPU) page on Saturday, February 22, 2025, at 8:00 AM WIB, the air quality index in Riau was 79.

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

The ISPU calculation is 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 the Minister 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.

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

Below Riau, Central Java has the second worst air quality in Indonesia with an index of 70. East Java is in third place with an air quality index of 69.

This means that no region has hazardous air quality.
