| Summary: | DKI Jakarta, densely populated city with heavy traffic activity, has a large potential
for hydrocarbon emissions. Hydrocarbon compounds are produced from motor
vehicle emissions and the degradation of organic compounds under anaerobic
conditions. Hydrocarbon its self is divided into 3 groups, namely Methane
Hydrocarbon (MHC), Non-Methane Hydrocarbon (NMHC), and Total
Hydrocarbon (THC). The concentration of hydrocarbons at a certain level will
reduce the ambient air quality. The purpose of this study’s to analyze the diurnal
variation of hydrocarbon and determine the correlation between concentration and
meteorological factor. Based on data from AQMS in DKI Jakarta in 2018-2020,
the total data on SPKU DKI 1 that does not meet the quality standards is 60.78%,
SPKU DKI 3 is 26.5%, and DKI 5 is 68.7%. It also shows that there were
concentration fluctuations due to photochemical reactions during the day, and
changes in traffic activites as well. The consentration of hydrocarbon was
increasing in 2018 to 2019, with the location having the highest concentration was
Central Jakarta, followed by West Jakarta, and the smallest was South Jakarta.
From the correlation test, it’s found a negative correlation between THC, MHC,
and NMHC with solar radiation, wind speed, and air temperature. In addition,
there is negative correlation between rainfall with THC and MHC in Central
Jakarta and West Jakarta, but positive correlation is found between NMHC and
rainfall in South Jakarta. The last factor, there’s positive correlation between
humidity and all hydrocarbon parameters in all regions.
