Relief (Recursive Elimination of Feature) method for Solar Home System (SHS) analysis in Delta Mahakam

Abstract

Abstract The area of Delta Mahakam has not been accessible by an electricity network for a long time and has been relying on gasoline as a source of electric power generation for daily and economic activity. The community uses the Solar Home System (SHS) unit for their home and public facility. The provision of these SHSs units was an activity of a community development program from a company having industrial activity in the area. This research aims to identify the SHS unit’s condition and the attributes relevant to the condition of the SHS unit. An SHS condition was determined by gathering data on the technical specification such as unit power size and battery capacity, electricity utilization, and its financing model. Data is collected using field survey, data collection, and interviews with respondents. The data was then analysed by the Recursive Elimination of Feature (Relief) method to select features sensitive to the condition of the SHS unit. The result of this study showed that the majority of SHS units are still functional to satisfy the electricity need. The set of attributes used in this research were accurate for the intended classes of SHS condition. This result provides information beneficial to improve the existing program and impact the community.
