Abstract
Amid the global COVID-19 pandemic, movement restrictions were implemented by various countries, Indonesia being among them. In this study, Jakarta, the capital city of Indonesia, serves as a focal point to elucidate the influence of such restrictions on air quality. Data, spanning from January to April 2020, were obtained from reputable sources including the Indonesian Meteorological Agency, Air Quality Index (AQI) platforms, IQAir, and Jakarta’s open data repository. Upon meticulous analysis, it was observed that diminished human activities in Jakarta resulted in a notable enhancement of air quality, with a variance of 19 days of superior air quality compared to the previous year. For a comprehensive understanding, comparative analyses with neighbouring cities were undertaken. In Singapore, reductions ranging from 8% to 43% were discerned in PM10, PM2.5, CO2, and SO2 levels. Bangkok reported a decline of 22% in PM2.5 concentrations, whereas Kuala Lumpur exhibited reductions in PM2.5 levels, varying between 3% and 35%, with further reductions of 3% to 63% in NO2 concentrations. Concurrently, SO2 levels saw a decrease of 2% to 48%, and CO concentrations diminished by 1% to 27%. The findings underscore the dual benefits of mobility restrictions, addressing both the containment of COVID-19’s proliferation and substantial improvements in environmental air quality.
