Analysis Of The Contribution Of Weather Modification Technology To The Gross Regional Domestic Product (Grdp) Of Purwakarta Regency West Java, Indonesia

Abstract

Since the establishment of the Center for Weather Modification Technology (WMTC) in 1985, Weather Modification Technology (WMT) flight operations have been carried out in various regions in Indonesia, such as in Sumatra, Java, Kalimantan, Sulawesi, West Nusa Tenggara, and Bali. However, from 1979 until now, the research on the economic benefits of implementing Weather Modification Technology (WMT) has never been analyzed, and its influence on the economy or Gross Regional Domestic Product (GRDP) has not been evaluated. The indicator of economic growth is the increase in production capacity and services over a certain period of time. Generally, economic growth is defined as an increase in the ability of a country's or region's economy to produce goods and services (GDP/GRDP). Water generated from Weather Modification Technology activities can make a significant contribution to the regional economy, especially in relation to water availability for various needs such as hydroelectric power generation, drinking water, industrial water, and agriculture. This research aims to analyze and evaluate the contribution of WMT to the economy of the Purwakarta Regency in West Java. The scope of the research is focused on the Purwakarta Regency, analyzing the impacts of the implementation of WMT for the purpose of filling the Citarum River Basin (Jatiluhur Reservoir). The research data consists of secondary data collected from operational reports of CWTMC, the Central Bureau of Statistics (Central and Purwakarta Regency Statistics Office), and the Office of the Department of Food Crops and Agriculture of Purwakarta Regency. The data analysis technique used is multiple regression modeling with the response variables (Y/Electricity and Drinking Water Sector of GRDP) and predictor variables: Electricity Production (X₁), PDAM Water Supply (X₂), Industrial Water Supply (X₃), and Agricultural/Rice Field Water Supply (X₄). By using multiple linear regression modeling, it can be explained that the additional rainwater contribution to Electricity Production (X₁), P DAM Water Supply (X₂), Industrial Water Supply (X₃), and Agricultural/Rice Field Water Supply (X₄) contributes 93.12% to the Electricity and Drinking Water Sector GRDP of Purwakarta Regency from the additional water provided by the WMT activities carried out by WMTC.
