Abstract

A survey was performed to assess the quality of ambient air in Jakarta, Bogor, Depok, Tangerang and Bekasi. Ambient air samples were collected from 33 sampling points at a distance of 0 meter and 120 meters from each main roads respectively. The highest average content of TSP in ambient air at 0 meter was found in West Jakarta (652.02 mg/cu.m) and that of 120 meters from the main road was in Bekasi (445.46mg/cu.m ). The highest difference of the TSP content between the two sampling points was in Kebon Jeruk, West Jakarta (96.62 %), and the lowest one was in Cikarang, Bekasi (1.63 %). Furthermore, the highest difference of the PM-10 content between the two sampling points was in Jalan Raya Bogor, Depok (96.86 %), and the lowest one was in Cikarang, Bekasi (17.26 %). In the whole areas of study, the average content of TSP was 522.44mg/cu.m (0 meter), and 178.09mg/cu.m (120 meters) , so the difference of the pollutant content between the two sampling points was 65.91 %. Meanwhile, the average content of PM-10 was 326.25mg/cu.m (0 meter), and 97.09mg/cu.m (120 meters), so the difference of the pollutant content between the two sampling points was 70.24 %. The difference of the means of both TSP and PM-10 content levels between the two sampling sites were significant. The percentages of sampling points complying with TSP level standard were 9.52 % (0 meter) and 75.76 % (120 meters from the road sides). While that of PM-10 were 18.18 % (road side sampling) and 78.79 % (120 meters from the road sides). Crusial measure for controlling the TSP and PM-10 pollution should also be addressed to mobile sources, such as reducing diesel motorized-vehicles and providing proper mass transportation.
