Abstract

nergi merupakan kebutuhan fundamental bagi kehidupan manusia. Salah satu alternatif energi terbarukan adalah Pembangkit Listrik Tenaga Mikrohidro (PLTMH), yaitu sistem pembangkit skala kecil yang memanfaatkan aliran air. Pada PLTMH, turbin crossflow banyak digunakan, namun memiliki keterbatasan dalam menghasilkan daya. Penelitian ini bertujuan untuk menganalisis pengaruh rasio sudu terpancung berpenampang segitiga terhadap kinerja turbin crossflow poros horizontal. Penelitian ini menggunakan metode eksperimen dengan memvariasikan rasio sudu terpancung  0,2; 0,4; 0,6, dibandingkan dengan sudu v yang tidak terpancung (rasio 1), dan plat datar (rasio 0) pada turbin crossflow poros horizontal. Jumlah sudu yang digunakan adalah 3 yang akan diuji dengan variasi kapasitas air sebesar, 11,024 L/s, 14,322 L/s,  dan 18,113 L/s dengan variasi pembebanan terhadap daya dan efisiensi. Hasil penelitian menunjukkan bahwa daya maksimum diperoleh pada rasio sudu terpancung 0,4 dengan kapasitas aliran 18,113 L/s dan beban 8000 gram sebesar 4,204 Watt. Efisiensi tertinggi dicapai pada rasio sudu terpancung yang sama, yaitu 0,4, dengan kapasitas 11,024 L/s dan beban 5000 gram sebesar 85,77%. Pencapaian ini disebabkan karena pada rasio sudu terpancung 0,4 aliran dapat dimanfaatkan secara lebih optimal sehingga menghasilkan putaran (RPM) yang tinggi serta torsi yang lebih besar.   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.
