Energy is a fundamental need for human life. One renewable energy alternative is the Microhydro Power Plant (PLTMH), a small-scale power generation system that utilizes water flow. In PLTMH, crossflow turbines are widely used, but have limitations in generating power. This study aims to analyze the effect of the truncated blade ratio with a triangular cross-section on the performance of a horizontal-axis crossflow turbine. This study uses an experimental method by varying the truncated blade ratio of 0.2; 0.4; 0.6, compared to untrimmed v-blades (ratio 1), and flat plates (ratio 0) in a horizontal-axis crossflow turbine. The number of blades used is 3 which will be tested with variations in water capacity of 11,024 L/s, 14,322 L/s, and 18,113 L/s with variations in loading on power and efficiency. The results of the study showed that the maximum power was obtained at a cut-off blade ratio of 0.4 with a flow capacity of 18.113 L/s and a load of 8000 grams of 4.204 Watts. The highest efficiency was achieved at the same cut-off blade ratio, namely 0.4, with a capacity of 11.024 L/s and a load of 5000 grams of 85.77%. This achievement was due to the fact that at a cut-off blade ratio of 0.4 the flow could be utilized more optimally, resulting in high rotation (RPM) and greater torque.
