Abstract

Pemanfaatan Gravitational Water Vortex Power Plant (GWVPP) sebagai Pembangkit Listrik Tenaga Mikrohidro (PLTMh) berpotensi untuk perceptan pemanfaatan hydropower di Indonesia. Kualitas aliran yang dihasilkan vortex dipengaruhi oleh beberapa parameter, diantaranya adalah kecepatan tangensial, vortex height, dan vortex strength. Pada penelitian ini dilakukan analisis terkait pengaruh posisi deflektor terhadap kinerja GWVPP. Data yang dianalisis berupa torsi, vortex height, daya mekanik, daya hidrolik, dan efisiensi sebagai data kuantitatif untuk menilai performansi GWVPP yang diperoleh. Studi eksperimental ini dilakukan dengan variasi penggunaan deflektor dengan panjang 20 cm, 30 cm, dan 40 cm dan lebar kanal sebesar 13 cm, 10 cm, dan 7 cm serta variasi yang tidak menggunakan deflektor. Berdasarkan uji eksperimental yang telah dilakukan, didapatkan bahwa deflektor memiliki peran penting dalam meningkatkan kecepatan air pada kanal inlet. Penambahan deflektor pada kanal inlet menyebakan penyempitan kanal inlet dan membuat kecepatan aliran air pada kanal meningkat setelah berinteraksi dengan deflektor. Berdasarkan hasil eksperimen, penambahan deflektor dengan panjang 40 cm dan lebar kanal 7 cm serta pada kondisi 200 RPM menghasilkan daya mekanik tertinggi dibandingkan variasi lain dimana daya pada variasi tersebut sebesar 4,964 Watt. Selain itu, efisiensi tertinggi didapatkan pada variasi penambahan deflektor dengan panjang 40 cm dan lebar kanal 10 cm serta pada kondisi 200 RPM dengan nilai efisiensi pada variasi tersebut sebesar 79,675%.

The utilization of the Gravitational Water Vortex Power Plant (GWVPP) as a Microhydro Power Plant had the potential to accelerate the utilization of hydropower in Indonesia. The quality of the flow produced by the vortex was influenced by several parameters, including tangential velocity, vortex height, and vortex strength. This study conducted an analysis of the effect of deflector position on the performance of the GWVPP. The data analyzed included torque, vortex height, mechanical power, hydraulic power, and efficiency as quantitative data to assess the performance of the obtained GWVPP. This experimental study was carried out with variations in the use of deflectors with lengths of 20 cm, 30 cm, and 40 cm, and channel widths of 13 cm, 10 cm, and 7 cm, as well as variations without using a deflector. Based on the experimental tests conducted, it was found that the deflector played an important role in increasing the water velocity at the inlet channel. Adding a deflector to the inlet channel caused a narrowing of the inlet channel and increased the water flow velocity after interacting with the deflector. Based on the experimental results, the addition of a 40 cm long deflector and a 7 cm wide channel at 200 RPM produced the highest mechanical power compared to other variations, with the power in this variation being 4.964 Watts. Additionally, the highest efficiency was obtained by adding a 40 cm long deflector and a 10 cm wide channel at 200 RPM, with the efficiency value in this variation being 79.675%.
