Banten's Nighttime Air Quality (Feb 10) is the Worst in Indonesia

Banten's air quality tonight is the worst in Indonesia. Based on the Air Pollution Standard Index (ISPU) page of the Ministry of Environment and Forestry (KLHK) on Tuesday (February 10, 2026) at 6:00 PM WIB, it was revealed that Banten's air quality index is 100.

According to KLHK's Air Pollution Control Directorate, ISPU is a unitless number used to describe ambient air quality conditions at a specific location, based on impacts on human health, aesthetic value, and other living beings.

ISPU calculations are 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 Minister of Environment and Forestry Regulation No. 14 of 2020 concerning the Air Pollution Standard Index, an ISPU range of 0-50 means good air quality, 51-100 means moderate air quality, and 101-200 means unhealthy air quality that is harmful to humans, animals, and plants.

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

Below Banten, North Sumatra ranks second worst in Indonesia with an air quality index of 99. Then, Riau is in third place with an air quality index of 95.

This means no region has hazardous air quality.
