Abstract

Drought is a natural disaster often found in various countries, including Indonesia. Rainwater harvesting can reduce the impact of drought by providing an alternative water source for daily needs. This research aims to determine the effectiveness of rainwater harvesting using rainwater harvesting installations to meet community water needs and reduce surface runoff which causes soil erosion. The potential for rainwater harvesting is calculated as adequate rain, where evapotranspiration is calculated using the Penman-Monteith Method in CROPWAT 8.0 for nine research location points. Surface runoff is calculated using the SCS Curve Number (CN) method. The research results show that the rain harvesting can help meet an average of 11-41% of water needs per capita and reduce around 0.71% of surface runoff generated from each resident's house. The results of this research can be a reference in developing the rain harvesting technology for soil and water conservation.
