The Effectiveness of Weather Modification Technology in Handling Air Pollution in DKI Jakarta

Abstract

Currently, the issue of air pollution is one of the pressing challenges in Indonesia, especially in the Jakarta area. Low rainfall during the dry season can cause pollutants in Jakarta's air space, especially PM2.5 concentrations, to increasingly accumulate, thereby worsening air quality. This research aims to analyze the effect of rainfall on PM2.5 concentrations during the dry season and analyze rainfall produced through Weather Modification Technology interventions in Jakarta. The data analysis used is simple linear regression using SPSS with rainfall data from BMKG and PM2.5 concentrations from KLHK with a period from January - October 2023 in Jakarta as well as analysis of GSMaP rainfall data from 6 - 23 August 2023 (before the implementation of the Weather Modification Technology) and 24 August – 10 September 2023 (during the Weather Modification Technology implementation) using GrADS to determine the rainfall distribution map in the seedling area (Jabodetabek). The research results show that there is an influence between the independent variable, namely rainfall, and the dependent variable, namely PM2.5 concentration, which is 6.3%. Meanwhile, 93.7% are other factors/parameters that were not studied by researchers. During the implementation of Weather Modification Technology, there was an increase in rainfall, especially in the DKI Jakarta, Depok, Tangerang and Bekasi areas with a fairly even rainfall distribution pattern, where before the implementation of Weather Modification Technology there was no rainfall observed, especially in the DKI Jakarta, Depok, Tangerang and Bekasi areas. And this indicated that the rain produced by Weather Modification Technology was effective in reducing the pollutant index.
