<![CDATA[Micro-Hydropower (MHP) is a renewable energy source that can be utilized to generate electricity on a small scale. This study aims to analyze the effect of water pressure variations on the performance of a laboratory-scale Pelton turbine and compare the performance of a single-nozzle and a double-nozzle system. The research method used was an experimental method with pressure variations of 2, 2.5, and 3 kg/cm² and electrical loads of 5–25 watts. Observed parameters included turbine rotation, voltage, current, output power, and system efficiency. Test results showed that increasing water pressure increased turbine output power and efficiency in both nozzle configurations. In the single-nozzle configuration, the maximum output power reached 15.19 W with a peak efficiency of 9.8% at a pressure of 3 kg/cm². Meanwhile, in the double-nozzle configuration, the maximum output power was 11.12 W with an efficiency of 7.2% at the same pressure. In general, the single-nozzle configuration performed better than the double-nozzle configuration in a laboratory-scale Pelton turbine system due to a more optimal water jet distribution and lower hydraulic losses.]]>
