Abstract
Gravitational Water Vortex Power Plant (GWVPP) merupakan salah satu jenis teknologi energi terbarukan yang menggunakan sumber air dan tergolong mikro-hidro karena pembangkit listrik yang tercatat tidak melebihi 100 kW. Penelitian terhadap GWVPP dibagi menjadi tiga kelompok variabel, yaitu konfigurasi basin, konfigurasi kanal dan konfigurasi turbin. Pada penelitian ini dilakukan studi eksperimental pada konfigurasi turbin dengan menggunakan susunan multi-stage dengan dua runner. Parameter yang digunakan sebagai penentu performansi pada GWVPP adalah torsi, RPM, daya poros, dan efisiensi sebagai data kuantitatif. Uji eksperimental pada multi-stage dilakukan dengan variasi jarak 1D (12 cm), 1.25D (15 cm) dan 1.5D (18 cm). Berdasarkan uji eksperimental yang telah dilakukan, didapatkan bahwa efisiensi akibat perubahan jarak antar runner memiliki pola linear positif dengan nilai efisiensi terbaik didapatkan pada jarak 1.5D (18 cm) yaitu sebesar 43,73%. Hal tersebut diakibatkan karena jarak antar runner memberikan ruang untuk pembentukan ulang vortex (re-originasi). Pergeseran sudut antar runner dilakukan pada seluruh jarak antar runner yang telah dilakukan sebelumnya dimana variasi pergeseran sudut yang digunakan adalah 0°, 15°, 30° dan 45°. Didapatkan bahwa hasil terbaik adalah pada jarak 12 cm dengan pergeseran sudut 15° dengan efisiensi yang dihasilkan sebesar 53,96%. Hal tersebut dipengaruhi karena adanya eddy yang terbentuk pada variasi lain sehingga mempengaruhi besar torsi yang dihasilkan.

Gravitational Water Vortex Power Plant (GWVPP) is one type of renewable energy technology that uses water sources and is classified as micro-hydro because the recorded power generation does not exceed 100 kW. Research on GWVPP is divided into three groups of variables, namely basin configuration, canal configuration and turbine configuration. In this research, an experimental study was conducted on the turbine configuration using a multi-stage arrangement with two runners. The parameters used to determine the performance of GWVPP are torque, RPM, shaft power, and efficiency as quantitative data. Experimental tests on the multi-stage were carried out with distance variations of 1D (12 cm), 1.25D (15 cm) and 1.5D (18 cm). Based on the experimental tests that have been carried out, it is found that the efficiency due to changes in the distance between runners has a positive linear pattern with the best efficiency value obtained at a distance of 1.5D (18 cm) which is 43.73%. This is because the distance between runners provides space for vortex re-formation (re-origination). Shifting the angle between runners is done at all distances between runners that have been done before where the angle shift variations used are 0 °, 15 °, 30 ° and 45 °. It was found that the best result was at 12 cm with an angle shift of 15° with a resulting efficiency of 53.96%. This is influenced by the eddy that is formed in other variations so that it affects the amount of torque produced.
