Abstract

Meningkatnya permintaan energi dan menurunnya cadangan energi fosil mendorong pengembangan energi baru dan terbarukan. Salah satu potensi energi terbarukan yang besar di Indonesia adalah energi air. Gravitational Water Vortex Power Plant (GWVPP) merupakan teknologi PLTMH yang dapat menghasilkan energi pada ketinggian hidrolik rendah. Kinerja GWVPP dapat dipengaruhi oleh jenis runner dan flow rate. Penelitian ini bertujuan untuk menganalisis pengaruh jenis runner dan flow rate terhadap kinerja GWVPP. Penelitian ini dilakukan secara eksperimental di Laboratorium Rekayasa Energi dan Pengkondisian Lingkungan Teknik Fisika FTIRS ITS dengan menggunakan flume tank. Studi eksperimental dilakukan dengan menerapkan tiga jenis runner, yaitu propeller, turgo, dan cross – flow yang diuji dengan tiga variasi flow rate, yaitu 0,0093 m³/s; 0,0104 m³/s; dan 0,0129 m³/s. Pada penelitian menunjukkan bahwa jenis runner memiliki pengaruh signifikan terhadap kinerja GWVPP. Runner propeller menghasilkan daya mekanik dan efisiensi terbesar dibandingkan runner turgo dan cross – flow. Daya mekanik dan efisiensi yang dihasilkan oleh runner cenderung meningkat seiring bertambahnya flow rate. Runner propeller menghasilkan daya maksimum sebesar 6,304 Watt dengan efisiensi sebesar 62,335% pada flow rate 0,0129 m³/s dan kecepatan angular 200 RPM. Runner turgo menghasilkan daya maksimum 4,022 Watt dan efisiensi 42,31% pada flow rate 0,0129 m³/s dan kecepatan angular 100 RPM. Runner cross – flow menghasilkan daya maksimum 3,411 Watt dan efisiensi 38,435% pada flow rate 0,0129 m³/s dan kecepatan angular 100 RPM.

Increasing energy demand and declining fossil energy reserves encourage the development of new and renewable energy. One of the great renewable energy potentials in Indonesia is water energy. Gravitational Water Vortex Power Plant (GWVPP) is an MHP technology that can produce energy at low hydraulic heights. The performance of GWVPP can be influenced by the type of runner and flow rate. This study aims to analyze the effect of runner type and flow rate on GWVPP performance. This research was conducted experimentally at the Laboratory of Energy Engineering and Environmental Conditioning of Physics Engineering FTIRS ITS using a flume tank. The experimental study was conducted by applying three types of runners, namely propeller, turgo, and cross – flow which were tested with three flow rate variations, 0,0093 m³/s; 0,0104 m³/s; and 0,0129 m³/s. The study showed that the runner type has a significant influence on the performance of GWVPP. The propeller runner produces the greatest mechanical power and efficiency compared to the turgo and cross – flow runners. The mechanical power and efficiency generated by the runner tend to increase as the flow rate increases. The propeller runner produces maximum power of 6,304 Watt and efficiency of 62,335% at a flow rate of 0,0129 m³/s and angular velocity of 200 RPM. The turgo runner produces maximum power of 4,022 Watt and efficiency of 42,31% at a flow rate of 0,0129 m³/s and angular velocity of 100 RPM. The cross – flow runner produces maximum power of 3,411 Watt and efficiency of 38,435% at a flow rate of 0,0129 m³/s and an angular velocity of 100 RPM.
