Abstract

Limited access to electrical energy in rural areas and catfish farming locations located far from the national electricity grid remains a major challenge, particularly for lighting needs at night. Adequate lighting is essential to support pond monitoring, security, and the continuity of aquaculture activities. This research aims to design, develop, and test a portable Solar Power Plant (PLTS) as an alternative and renewable energy source for lighting systems in catfish farming. The research method applied is Research and Development (R&D) with an experimental approach, covering system planning, energy requirement analysis, component selection, system assembly, and field performance testing. The portable PLTS system is composed of a 50 Wp solar panel, energy storage batteries, an MPPT solar charge controller, an inverter, and LED lamps as the primary electrical load. Performance testing was conducted directly at the catfish farming site to evaluate output power stability, lighting duration, and system reliability during nighttime operation. The experimental results indicate that the portable PLTS system is capable of supplying sufficient and stable electrical energy to meet lighting demands effectively. The use of LED lamps significantly improves energy efficiency and reduces overall power consumption. Furthermore, the portable design allows flexibility in installation and mobility, making it suitable for remote aquaculture locations. Overall, the developed portable PLTS system is feasible, environmentally friendly, and effective as an alternative energy solution to support sustainable catfish farming activities
