Air quality in the Jabodetabek area has improved this evening, but it remains unhealthy for sensitive groups.

Tangerang's air quality this afternoon is the worst in the Jabodetabek area, based on Air Pollutant Standard Index (ISPU) data from the Ministry of Environment and Forestry (KLHK). Tangerang's air quality index was recorded at 86 on Tuesday (January 9, 2024) at 5:00 PM WIB.

East Jakarta follows, ranking second with an air quality index of 84. West Jakarta is third with a score of 82.

For information, KLHK categorizes air quality based on the following ISPU ranges:

* 0-50: Good
* 51-100: Moderate
* 101-200: Unhealthy
* 201-300: Very Unhealthy
* 300+: Hazardous

The air quality index or ISPU is monitored at 72 stations spread across 31 provinces. The air quality index calculation uses measurement results of air pollutant parameters, consisting of particulate matter (PM2.5 and PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon dioxide (CO2), carbon monoxide (CO), ozone (O3), and hydrocarbons (HC).

This indicates that cities in Jabodetabek such as Bogor have good air quality, while Tangerang, East Jakarta, West Jakarta, South Tangerang, Depok, North Jakarta, South Jakarta, and Central Jakarta have moderate air quality.

KLHK advises that individuals in areas with unhealthy air quality should reduce prolonged outdoor physical activity. In areas with moderate air quality, everyone can still engage in outdoor activities except for sensitive groups.

Those living in areas with very unhealthy and hazardous air quality should avoid all outdoor activities.
