10 Indonesian Regions with the Worst Air Quality (Sunday, September 3, 2023)

Air quality in Central Kalimantan this afternoon is the worst in Indonesia. According to the Ministry of Environment and Forestry (KLHK)'s Air Pollutant Standard Index (ISPU) page on Sunday (September 3, 2023) at 4:00 PM WIB, the air quality index in Central Kalimantan was 245.

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. Measurements of these air pollutant parameters are taken at 72 stations across 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 detrimental 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 over 300 can seriously harm health and requires immediate action.

Below Central Kalimantan, West Java is ranked second worst in Indonesia with an air quality index of 135. Then, in third place is West Kalimantan with an air quality index of 134.

This means that the top three provinces have unhealthy air quality.

The following is a list of the 10 provinces with the worst air quality in Indonesia on Sunday, September 3, 2023, at 4:00 PM WIB.
