| Summary: | DKI Jakarta as a big city with a high population density and varied population activities that
affect the formation of air pollutants, one of them are hydrocarbon compounds. Hydrocarbons
are classified into Total Hydrocarbons (THC) which is the total of Non-Methane
Hydrocarbons (NMHC) and Methane Hydrocarbons (MHC). Landuse differences at each
monitoring location, number of vehicles, and hydrocarbon involvement in photochemical
reactions leads to hydrocarbon concentration temporal and spatial variations. This study aims
to perform spatial temporal analysis of hydrocarbon compounds and analyze the correlation
of hydrocarbon and NOx, NO, NO2, O3, BTEX compounds. Based on available
observational data in 2018 – 2019, it is known that there are seasonal and annual temporal
variations, as well as spatial variations shows that the highest hydrocarbon concentration
found in DKI 1 (Bundaran HI, Central Jakarta), then DKI 5 (Kebon Jeruk, West Jakarta), and
finally DKI 3 (Jagakarsa, South Jakarta). The results of the correlation test in DKI 1 and DKI
5 shows a directly proportional with NOx, NO2, NO, and O3 compounds, while in DKI 3 it
was the other way around. In addition, the correlation results in DKI 1 and DKI 5 shows an
inversely proportional to BTEX compounds, while in DKI 3 shows directly proportional. |
