Scenarios of Reducing Emissions Air Pollutants (SO2, NOx, CO, and PM2.5) in the Power Generation and Residential Sector in DKI Jakarta Province
Keywords:DKI Jakarta Province, Power generation, Residential, Air Pollution, ABC-EIM, Reducing Emissions.
The Air Pollutant Standard Index (ISPU) showed that the air quality in DKI Jakarta Province is in decreasing trend. It can be seen from ISPU’s “Unhealthy” category from 2014 – 2018 which tends to increase; hence air pollution has become a real environmental problem. Efforts to reduce emissions need to be made by creating a scenario for reducing air pollutant emissions of SO2, NOx, CO, and PM2.5 generated from the power generation and residential sectors as the basis for improving air quality in DKI Jakarta Province. Emissions estimates use a top-down approach to common emission factors combined with high-level (national) activity data with the help of the atmospheric brown clouds (ABC) excel workbook – emission inventory manual (EIM) tool The power generation sector in DKI Jakarta Province mainly uses natural gas as its fuel, with the parameter NOx being the most emitted. The scenario for reducing emissions of air pollutants SO2, NOx, CO, and PM2.5 that can be done in the power generation sector is by gasifying power plants by converting the use of high-speed diesel fuel and marine fuel oil with natural gas target 100% by 2030 the fuel can be converted, where the most effective in reducing SO2 is 8.44% in 2030. Most of the residential sector in DKI Jakarta Province uses liquefied petroleum gas as fuel for cooking, with CO emission parameters being the most emitted. The scenario for reducing air pollutant emissions of SO2, NOx, CO, and PM2.5 that can be done in the residential sector is to substitute the use of LPG as fuel for burning gas stoves into electric stoves with a target of 4% by 2030 LPG can be substituted for electricity, where can be reduced all parameters effectively with the same percentage reduction with the target of reducing fuel consumption by 4% in 2030.
