This study aimed to determine the effects of magnet type, water discharge variation, and their interaction on the voltage, current, and output power of a Pelton turbine generator. The research employed an Experimental Laboratory Research method with a 2 × 3 factorial design. The independent variables consisted of magnet type (Neodymium N52 and Ferrite) and water discharge variations (220, 230, and 240 L/min). Each treatment combination was repeated 12 times, resulting in 72 observation data. Voltage and current data were measured using a digital multimeter, while the generator output power was calculated using the equation P = V × I. The collected data were analyzed descriptively and further examined using the Scheirer-Ray-Hare test. The results showed that both magnet type and water discharge had a significant effect on the voltage, current, and generator output power, whereas the interaction between magnet type and water discharge was not significant. The Neodymium N52 magnet consistently produced higher voltage, current, and output power than the Ferrite magnet under all water discharge variations. The highest average output power was 5.81 W, obtained using the Neodymium N52 magnet at a water discharge of 240 L/min, while the lowest average output power was 2.08 W, obtained using the Ferrite magnet at 220 L/min. Therefore, the combination of the Neodymium N52 magnet and a water discharge of 240 L/min provided the best generator performance
