Urgensi transisi menuju sumber energi terbarukan menuntut inovasi dalam pemanfaatan sumber daya lokal yang efisien dan berkelanjutan. Salah satu potensi yang menjanjikan adalah Gravitational Water Vortex Turbine (GWVT), yaitu sistem pembangkit listrik skala kecil yang memanfaatkan aliran air tanpa bendungan besar, cocok untuk daerah terpencil dengan aliran sungai kecil. Namun, efisiensinya sangat bergantung pada berbagai parameter geometri dan hidrolik. Untuk mengoptimalkan efisiensi GWVT, penelitian ini mengusulkan pendekatan Extreme Gradient Boosting (XGBoost). Hasil penelitian menunjukkan bahwa model mampu memprediksi efisiensi dengan nilai koefisien determinasi sebesar 0,89. Analisis sensitivitas menunjukkan bahwa debit air, jarak sudu outlet, dan diameter outlet merupakan parameter paling berpengaruh terhadap efisiensi. Hasil ini menunjukkan bahwa metode ini berpotensi menjadi alat prediksi yang efektif untuk mendukung optimasi desain Gravitational Water Vortex Turbine.
