<![CDATA[The population density and increasing number of vehicles in Bekasi City have the potential to increase air pollution, especially PM2.5 and PM10 concentrations in Bekasi City. This study aimed to analyze the effectiveness of the Patriot Bina Bangsa Urban Forest (PBB UF) in reducing the concentrations of PM2.5 and PM10 pollutants; measure the ability of leaves from dominant tree species in PBB UF to adsorb particulate pollutants; and analyze the impact of distance, vehicle emissions, Leaf Area Index (LAI), speed, and wind direction on reducing PM2.5 and PM10 concentrations in PBB UF, Bekasi City. The research was conducted using field observations,gravimetry, and literature studies. The effectiveness of Patriot Bina Bangsa Urban Forest in reducing PM2.5 concentration was 14.40% while PM10 was 20.81%. A three-week study of dust absorption by the leaves of the broad-leaved mahogany (Swietenia macrophylla) showed that the leaves’ ability to absorb dust increased each week. The average ability of leaves to adsorb daily dust was 14,192.23µg/cm2, with the largest percentage decrease occurring at a distance of 0–10 m (43.07 %). Dust absorption capacity decreases as the distance from the dust source increases. It is suspected that vehicle emissions are the most dominant variable influencing PM2.5 and PM10 concentrations in PBB UF.]]>
