Abstract

This study aims to investigate the impact of rainfall on the characteristics of particulate matter 2.5 in Jakarta city. The particulate matter 2.5 has an adverse impact on human life, while the precipitation reduces concentrations of pollutants in the environment, thus the scavenging effect of PM2.5 by precipitating must be investigated. It needs secondary data of PM 2.5 taken from the AirNow Department of State, meanwhile rainfall data has been extracted from the Meteorological, Climatological, and Geophysical Agency (BMKG). Some analyses have been conducted to understand the influence of rainfall impact on PM 2.5 presence in the atmosphere above Jakarta city. The windrose analysis is performed to know the amount of pollutants transported in one location. Then, the fluctuations in rainfall juxtaposing with the average PM 2.5 concentration to see PM 2.5 concentration while rainfall exists. Subsequently, the data correlations are analyzed using a correlation test based on the Spearman correlation method. As a result, the scarcity of rainfall results in elevated concentrations of PM 2.5, and most likely when higher rainfall, the lower PM 2.5 concentration. Moreover, there is a significant correlation between precipitation levels and PM 2.5 concentrations, as evidenced by the 2019 data, which exhibits an R-value of -0.52.
