Jakarta is the capital of Indonesia which has very rapid development and progress in various fields and sectors. The physical development of cities and the establishment of industrial centers accompanied by surging motor vehicle production, resulted in an increase in traffic density which is one of the causes of increased air pollution in cities. One of the pollutants that contribute to air pollution in cities is nitrogen dioxide (NO2). In this study, an analysis of GIS spatial variations was carried out to identify NO2 concentration levels measured by passive samplers from preceeded work in 47 DKI Jakarta locations, based on land use maps. As indicative measurement results, the data were analysed for their relative variation rather than the actual values. Currently validation to estimate the concentration values is still on-going. The highest concentration comes from the DKI 1 area which is concentrated in the Bundaran HI. Meanwhile, Kantor Camat Tanah Abang is the location of research with the highest NO2 concentration data. The high NO2 concentration in the Bundaran HI is influenced by land use which is dominated by roads and settlements. Based on land use, the highest NO2 concentration occurs in residential areas spread throughout DKI Jakarta. The second highest concentration was found in water areas scattered in the West Jakarta area. While the lowest concentrations occurred in the East and North Jakarta and sub urban of the Kelapa Gading area which has green land. Then, there are variations of NO2 that are spatially distributed based on land use in each region and the activities in it. Based on seasonal distribution also shows spatial variations in DKI Jakarta based on an analysis of its meteorology.
