Abstract
One of the sources of PM2.5 pollution in urban areas comes from road transportation activities. Therefore it is necessary to monitor air quality to determine the concentration of PM2.5 roadside. This study aims to inventory the concentration of PM2.5 in roadside ambient air on collector roads in Bandung City. The inventory was carried out during the pandemic of Covid-19 in Oktober 2020 with two methods, a manual method using a Low Volume Air Sampler (LVAS) and an automatic method using a Particulate Counter. Measurement was conducted at 10 locations with a duration of 1 hour in the morning and evening. In addition, it was also carried out additional measurements of 2 hours and 12 hours. It was found that the ambient PM2.5 with the LVAS measurement is more fluctuating than the Particulate Counter measurement. Even though transportation activity tends to be lower during the pandemic, the ambient PM2.5 concentration for 1 hour ranged from 10.95 - 760.98 g/m3. This condition has exceeded the existing quality standard set by the Indonesian Government and WHO which is 65 g/m3 and 25 g/m3.
