Indonesia's 10 Most Polluted Areas: Where Does Jakarta Rank? (Saturday, September 23, 2023)

Air quality in South Sumatra 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, September 23, 2023, at 7:00 AM WIB, the air quality index in South Sumatra was 173.

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 (201-300) can increase health risks in sensitive groups. Meanwhile, hazardous air quality (over 300) can seriously harm health and requires immediate action.

Following South Sumatra, Central Kalimantan has the second-worst air quality in Indonesia with an index of 154. Then, in third place is South Kalimantan with an air quality index of 143.

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 Saturday, September 23, 2023, at 7:00 AM WIB:

1. South Sumatra: 173
