Effectiveness of SLIFA device installation for transportation sector especially on truck and bus to reduce the environmental impact in urban area of DKI Jakarta

Abstract

Based on data from the Ministry of Environment (KLH), the transportation sector is the largest source of air and greenhouse gas (GHG) pollutants in urban areas followed by other sources of fine pollutant emissions such as industry, households and commercial activities. GHG emissions from the transportation sector in the city are around 23% of total GHG emissions from all sources. The aim of this study is to reduce emissions on trucks and buses by installing the Speed Limiter and Driver Fatigue Analyzer (SLIFA). The SLIFA installed on trucks and buses that is operating in the city area. The analysis of smoke level with an exhaust emission meterfor monitoring several pollutants such as Carbon Dioxide (CO2), Carbon Monoxide (CO), Nitrogen Monoxide (NOx), and Sulphur Dioxide (SO2). The average opacity index at truck SG 500 before is 22% and it wasreduced to 16.6% after SLIFA installation. The analysis in bus OH 1526 obtained that the average opacity index before is 25.11%, and after installation, it was reducedto20.17%, analysed with Fleet Management Toolkit (FMT) Air Pollutants, Particulate Matter PM10, 3,3 ton/yr sulphur Oxides Sox 3,8 ton/yr, Nitrogen NOx Oxides ton/yr, Carbon Monoxide CO 77 ton/yr, Volatile Organic compound VOCs 11 ton/yr. The data showed that the installation of SLIFA was effective inreducing the exhaust emission of the trucks and buses and These tools can be used to reduce the risk of cancer, bronchitis and so on.
