Improved Engine Standard Scenarios to Reduce Emissions of Air Pollutants in Transportation Sector in Jakarta Indonesia

Abstract

Jakarta Province is a metropolitan city that is the center of the business economy in Indonesia, which makes it
as one of the cities with the highest pollution levels in Indonesia. One sector that significantly contributes is the
transportation sector. This research study analyzes transportation sector emissions in DKI Jakarta Province, Indonesia. It
is analyzed by comparing two scenarios, namely the Euro 4 scenario and the baseline scenario in 2030 to see the emission
reductions that can be generated by implementing the Euro 4 scenario. This study uses the Atmospheric Brown CloudEmission Inventory Manual (ABC-EIM) in calculating the estimated emissions generated. In 2030 it is estimated that the
transportation sector contributed 122271.17 tons of PM2.5 pollutant emissions, 137447.23 tons of NOx pollutants,
5005290.69 tons of CO pollution, and 131644.78 tons of SO2, where the most significant emissions produced by the
transportation sector are CO emissions. CO pollutant is produced from incomplete combustion, which is common in
vehicle engines. The application of euro 4 standard fuel is proven to reduce the number of emissions produced by the
transportation sector, with emission reductions produced by 40.29% for NOx pollutants, reducing CO pollutants by
33.61%, reducing SO2 pollutants by 27.96% and reducing pollutants PM2.5 is 26.95%.
