This research focuses on harnessing solar energy to enhance the efficiency and sustainability of agriculture in Gumelem Wetan Village, Banjarnegara Regency. The research aims to identify the potential of Solar Power Plants (PLTS) in the village. The objectives include gathering information on the potential of PLTS, understanding the electrical output of PLTS through the HOMER application as an electricity source in Gumelem Wetan Village, evaluating the efficiency of PLTS in powering water pumps for agricultural irrigation, and assessing the project investment costs for PLTS both in the field and through the HOMER application. The research methodology involves collecting PLTS specifications data and conducting direct measurements for both primary and secondary data using the HOMER software. The analysis reveals that Gumelem Wetan Village possesses a high solar energy potential, with an average intensity of 4.66 kWh/m2/day. HOMER simulations in the field result in an annual electrical output of 4,935 kWh, with an unmet electric load of 0.598% and excess electricity of 2,429. Similarly, PLTS system simulations yield 3,085 kWh/year, with an unmet electric load of 3.81% and excess electricity of 158. Furthermore, the research evaluates the efficiency of PLTS in powering water pumps for agricultural irrigation, considering primary data such as solar intensity over 17 days, load usage data, and voltage and current data from solar panels. The results demonstrate that PLTS can provide sufficient electricity for irrigation, despite some load discrepancies. Cost investment analysis indicates that the total project cost (NPC) in the field is Rp.105,801,100.00, with a Cost of Energy (COE) of Rp.2,247.64. Using calculations, the NPC becomes Rp.93,864,280.00 with a COE of Rp.2,060.58. This research serves as a foundation for decision-makers, planners, and researchers to plan the implementation of similar PLTS in different regions, considering varying environmental conditions. The results provide insights into the potential of PLTS as a source of electrical energy for agriculture, with positive impacts on sustainability and resource efficiency.
