Banten's Morning Air Pollution (Jan 15) Worst in Indonesia

Banten's air quality is the worst in Indonesia this morning. Based on the Air Pollution Standard Index (APSI) page of the Ministry of Environment and Forestry (KLHK) on Thursday (Jan 15, 2026) at 08:00 AM WIB, Banten's air quality index was 95.

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

APSI calculation is based on the measurement results of seven air pollutant parameters, namely PM10, PM2.5, NO2, SO2, CO, O3, and HC. Air pollutant parameter measurements are spread across 72 stations in various regions.

Based on KLHK Regulation No. 14 of 2020 concerning the Air Pollution Standard Index, an APSI in the range of 0-50 indicates good air quality, 51-100 means 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 more than 300 can seriously harm health and requires quick action.

Below Banten, Riau occupies the second-worst position in Indonesia with an air quality index of 91. Then, in the third position is Aceh with an air quality index of 86.

This means that no region has hazardous air quality.
