AIR POLLUTION from ROAD TRAFFIC – MEASUREMENT USING REGRESSION ANALYSIS
In transport sector, road transport or automobile is major source of Carbon Monoxide (CO) emission as the major global warming gas. It seems that CO emission from motorized are gradually becoming a serious problem for the health of human life. The methods of measuring emission content can be divided into two main methods: surveyed by tools and using formula. The first method need some equipments and fairly expensive. The main objective of this research is the analysis emission content measurement from motorized with regression formula.
The period of survey divided into four days (Wednesday, Friday, Saturday and Sunday) during peak hours ( 06:30 - 09.30 A.M), (12:30 A.M. - 3.30 P.M) and (4.30 P.M.- 7.30 P.M). The area of study located in RA Kartini Bandar Lampung, with five observed point to find the total numbers of vehicles passed by and the kind of vehicle. The primary data that collected are number and type of vehicles while secondary data are standard of gas emission output in Bandar Lampung .
Data were provided as graph and table of relation between volume, percentage and type of vehicles at certain period with emission content on the appointed research area. Data calculation will show emission content also type and volume of vehicles that surveyed. Then the result compared to the air-quality standard in Bandar Lampung. The results show that pollutant content produced by vehicles that passing by Jl. RA. Kartini Bandar Lampung achieved up to: CO = 55,345% ( 31,06905 ppm), more than air-quality standard (20 ppm); NO2 = 69,2864% ( 156,59 µg/m3), more than air-quality standard (92,5 µg/m3); Smoke = 49,23% ( 0,388 µg/m3), more than air-quality standard (0,26 µg/m3) and the last results is Pb = 4,467% ( 0,06268 µg/m3), more than air-quality standard (0,06 µg/m3).
