Abstract

The problem of energy shortages is still a global problem which is especially felt in developing countries whose residents live in villages, which still require the development of more efficient energy sources. The problem of meeting the availability of electricity in rural areas by utilizing water energy as new and renewable energy is a long-term goal in this research.  The goal is to obtain the value of the turbine power from the turbine design which is designed to later be able to fulfill a picohydro scale power plant. The current research on kinetic turbines is a combination of two types of waterwheels, which have a vertical axis (overshot turbine and pusher turbine). Most water turbines have fixed blades. In this research, the target of the novelty is a kinetic turbine with a vertical shaft which has a hinged blade. Hinged blades are blades that can move when the flow of water hits the blades, so that on one side of the turbine it will reduce negative torque and on the other hand it will increase turbine rotation. The results of the research that became the target were to obtain a turbine design that has more optimal turbine power and efficiency, compared to a turbine that has a fixed blade, so that this externally hinged blade kinetic turbine can contribute to the provision of rural electrical energy. The optimum value in this study is the number of blades 10 and turbine power 59.01 Watt.

Abstract

Renewable energy has become a global priority to reduce dependence on fossil fuels, with solar power offering significant potential, particularly in equatorial countries like Indonesia. Despite abundant solar energy resources, its utilization remains limited, underscoring the need for educational interventions that build technical competencies in renewable energy. This study aims to design, construct, and evaluate the performance of a 50 Wp off-grid Solar Photovoltaic (PV) Trainer Kit as an instructional medium for vocational and higher education laboratories. The research employed a design-based approach consisting of planning, product design, fabrication, and testing. The trainer kit integrates essential components including a polycrystalline solar module, inverter, charge controller, VRLA battery, and monitoring devices. Performance testing was conducted using true outdoor experimental methods, focusing on solar radiation intensity, charging efficiency, and discharging duration. Results indicate that under clear weather conditions, the trainer achieved full battery charging in 3.5 hours, while battery discharge under a 100 W AC load lasted approximately one hour. These findings confirm the trainer’s functional reliability and its potential as an effective learning medium. The study concludes that the developed trainer kit not only enhances practical learning of photovoltaic systems but also supports national efforts in renewable energy education. The research recommends further development with larger solar module capacity and alternative battery types to expand instructional applications.
