Jambi's Air Pollution Tonight (2/1) is the Worst in Indonesia

Air quality in Jambi 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 (2/1/2026) at 6:00 PM WIB, Jambi's air quality index was 99.

According to the Directorate of Air Pollution Control of KLHK, ISPU is a dimensionless number used to describe the ambient air quality conditions at a certain location and is based on its impact on human health, aesthetic value, and other living things.

ISPU calculations are based on the measurement results of seven air pollutant parameters, namely PM10, PM2.5, NO2, SO2, CO, O3, and HC. Measurements of air pollutant parameters are spread across 72 stations in various regions.

Based on Minister of Environment and Forestry Regulation No. 14 of 2020 concerning the Air Pollution Standard Index, an ISPU in the range of 0-50 indicates good air quality, a range of 51-100 means moderate air quality, and a range of 101-200 means 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 more than 300 can seriously harm health and requires prompt action.

Below Jambi, Banten ranks as the second worst in Indonesia with an air quality index of 95. Then, in third place is Aceh with an air quality index of 94.
