DKI Jakarta is the center of government and economy in Indonesia with an area of 7,659.02 km2 . In the last ten years, the population growth rate of DKI Jakarta is 0.92% per year. The rate of population growth support the increase of motorized vehicles. The increasing number of motorized vehicles has the potential to increase air pollution if there are no air quality management. The initial stage in carrying out air pollution is an emission inventory. The emission inventory focuses on highway in DKI Jakarta by calculating the emission load of carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO2), and particulate matter (PM2.5 and PM10). In conducting the inventory, the bottom-up emission estimation method is used with a traffic data database for each toll gate in DKI Jakarta from PT Jasa Marga to obtain data on fuel usage of highway in DKI Jakarta. The emission factor refers to the Guidelines for Developing Emission Inventory in East Asia 2011 and GAINS. The results of the 2017-2021 inventory show that gasoline cars produce the most CO and NOX at 13.829,52 ton and 3.895,61 ton in 2021. Diesel cars produce the most PM2.5, and PM10 at 563,71 ton and 583,112 ton in 2021. Light duty trucks produce the most SO2 689,4 ton in 2021. Emission load in 2021 is distributed spatially using the Geographic Information System (GIS) software. The results of the spatial distribution showsthat the highway with the highest pollutant emissions are Halim, Cililitan, Cengkareng, Meruya and Pluit.
