Abstract

Abstract: Energy needs to become an inseparable part of the community's living needs, along with the rapid increase in development. The supply of electricity is carried out by PT PLN (Persero), as an official institution appointed by the government to manage electricity problems in Indonesia, so far it has not been able to meet the community's need for electricity as a whole. So, it is necessary to develop the potential for renewable energy such as hydropower. Potential water resources that can be used as sources of electrical energy such as the Hydroelectric Power Plant and Micro-Hydro Power Plant. Based on these problems, this research was conducted to analyze the potential of micro-hydro using the Geographic Information System method with the Soil and Water Assessment Tool (SWAT) model and the application of spatial pattern plans to increase potential areas in micro-hydro development in Kelara Watershed, South Sulawesi. This research uses the Soil Water Assessment Tool (SWAT) model approach and the calculation of hydraulic power. Classification of land cover in 2015 in Kelara watershed with vegetation is 6, 469.45 ha (16.81%) of the total area of the watershed. The results showed that with 2015 land cover conditions, there were 22 sub-watersheds with the potential for micro-hydro development from 83 sub-watersheds in Kelara Watershed. Assuming a minimum of 10 kW of power is generated at any time, 12 sub-watersheds are obtained, which can be used for micro-hydropower plants. The implementation of the spatial plan in 2031 can reduce the number of potential sub-watersheds based on minimum discharge. The condition of land cover in 2015 amounted to 22 sub-watersheds, while in the spatial plan, there are 21 potential sub-watersheds.
