Air quality in Lampung this morning is the worst in Indonesia. Based on the Air Pollution Standard Index (APSI) page of the Ministry of Environment and Forestry (KLHK) on Saturday (18/10/2025) at 08.00 AM WIB, it was revealed that Lampung's air quality index was 136.

According to the Directorate of Air Pollution Control of KLHK, APSI is a unitless number used to describe ambient air quality conditions 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.

Furthermore, 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 prompt action.
