| Summary: | Air pollutant emissions need to be estimated accurately to ensure that air
management strategies are properly designed and implemented. The emission
factor (EF) is an empirical functional relationship between the emission of a
pollutant and the activity that causes it to form. The transportation sector is a key
and main aspect in the growth and development of cities, especially in DKI Jakarta.
One of the negative impacts arising from transportation activities is a decrease in
ambient air quality due to the emission of higher levels of pollutants into the
environment. The calculation of emission factors will be based on the results of
measuring vehicle emissions at 16 points in Jakarta using remote sensing methods
that measure the ratio of pollutants to CO2. In this study, specific emission factor
values were generated in DKI Jakarta, Indonesia for CO, NOx, and HC emissions
in gasoline-fueled and diesel-fueled passenger vehicles and light commercial
vehicles. For CO and HC emission factors, gasoline-fueled vehicles generally emit
higher emissions than diesel-fueled vehicles. As for the NOx emission factor, the
emission factor value is higher resulting from diesel-fueled vehicles. From this
study, it is also found that the emission factor of light commercial vehicles was
higher than passenger vehicles and the emission factor of taxis is also higher than
passenger vehicles. There is a trend of emissions reduction from vehicles with older
to modern vehicles. The most significant reduction in occurred in 2007 which could
be due to the influence of the applicable policy, the Decree of the Minister for the
Environment No.141/2003 concerning Thresholds for Exhaust Emissions for New
Types of Motor Vehicles and Vehicles in Production (Current Production). This
policy regulates the implementation of Euro 2/II equivalent emission standards for
motorcycles, cars and heavy vehicles. This study also produced emission factors
for various vehicle brands and also cylinder capacity.
