摘要：Applying pico hydro as a power plant in rural or remote areas to generate electricity is a possible solution. However, pico hydro is rarely applied because it is alleged that the funds needed are large for the energy potential survey due to requiring many human resources and the high risk of directly mapping meeting wild animals. Hence, a method is needed that can map the water-energy potential on a pico scale; this can accelerate the process of electrification in remote or rural areas. Thus, this study proposed tool to determine water energy potential for head utility Geographical Information System (GIS) based on Digital Elevation Model National (DEMNAS) of the Republic of Indonesia data, and discharge utility Manning approach and rainfall data. The GIS can be used as decision support because a potential location is detected accurately and precisely, and Manning's approach can be used as early data available discharge. From the mapping results, two locations are applicable for pico hydro: the undershot waterwheel and the breastshot waterwheel. The two turbines implemented presented good performance where the efficiency was close to their optimum limits.
