Analisis Perilaku Aliran Terhadap Kinerja Roda Air Arus Bawah Untuk Pembangkit Listrik Skala Pikohidro

– Electrical energy is a basic requirement for most Indonesians. However, Sidoharjo Village residents cannot fully experience it since the electricity from PLN often goes out, especially during the rainy season. On the other hand, Sidoharjo Village has a large enough water potential from the river in Dukuh Rancah, but it has not been optimally used. Micro Hydro Power Plant (PLTMH) is one effort that can be done. To do so, it is necessary to know the hydrological values which include the mainstay of the river, the river basin area (DAS), and the effectiveness of dropping water. The river's reliable discharge is calculated by using the F.J. Mock method, under the principle of evaporation and transpiration (evapotranspiration). The data required are monthly rainfall, number of rainy days, humidity, and sunlight intensity. The calculation by using Ms. Excel showed the river's reliable discharge value of 1.3147 m3/s with an effective dropping height of 6 meters capable of producing a potential water power of 77.46 kW, 69.71 kW of turbine power, and 66.22 kW of generator output power. Meanwhile, the simulation results using the HOMER application showed that the river has a power capacity of 65.9 kW, an average power of 63.4 kW, minimum power of 26.4 kW, and a maximum power of 74.1 kW. It used a Kaplan turbine with a system efficiency of 0.85. It means that if the community needs 23 kW of electricity, the river is suitable to be used as a micro-hydropower plant system.Keywords – micro-hydro, F.J. Mock method, evapotranspiration, HOMER Intisari – Energi listrik merupakan kebutuhan pokok bagi sebagian besar masyarakat Indonesia. Namun, kontinuitas suplai listrik tidak dapat dirasakan secara maksimal oleh masyarakat Desa Sidoharjo. Hal ini dikarenakan listrik dari PLN sering padam apalagi ketika musim hujan. Di sisi lain Desa Sidoharjo mempunyai potensi air yang cukup besar bersumber dari sungai Dukuh Rancah, tetapi belum dimanfaatkan secara optimal. Salah satu upaya yang dapat dilakukan adalah memanfaatkannya sebagai Pembangkit Listrik Tenaga Mikro Hidro (PLTMH). Untuk mengetahui besar potensi sungai sebagai pembangkit energi listrik perlu diketahui nilai-nilai hidrologi yang meliputi debit andalan sungai, luas daerah aliran sungai (DAS), dan tinggi jatuh efektif air. Perhitungan debit andalan sungai dilakukan menggunakan metode F.J. Mock, yaitu berdasarkan prinsip evaporasi dan transpirasi (evapotranspirasi). Data yang diperlukan adalah curah hujan bulanan, jumlah hari hujan, kelembaban udara, dan intensitas cahaya matahari. Hasil perhitungan menggunakan Ms. Excel menunjukkan nilai debit andalan sungai 1,3147 m3/s dengan tinggi jatuh efektif air 6 meter mampu menghasilkan potensi daya air sebesar 77,46 kW, daya turbin 69,71 kW, dan daya keluaran generator 66,22 kW. Sedangkan hasil simulasi menggunakan aplikasi HOMER menunjukkan bahwa sungai memiliki kapasitas daya sebesar 65,9 kW, daya rata-rata 63,4 kW, daya minimum 26,4 kW, dan daya maksimum 74,1 kW. Adapun turbin yang digunakan adalah turbin jenis kaplan dengan efisiensi sistem 0,85. Artinya jika kebutuhan listrik masyarakat sebesar 23 kW, maka sungai Dukuh Rancah layak dijadikan sebagai sistem pembangkit listrik tenaga mikro hidro.Kata kunci – mikro hidro, Metode F.J. Mock, evapotranspirasi, HOMER

“…Pada pengujian performansi kincir air, cara yang terbaik memperlihatkan nilai besaran torsi, banyaknya putaran, dan tenaga koversi yang diperoleh dari kecepatan relatif air yang mengalir di diarea kincir terpasang. Hasil yang diperoleh pada uji pertama, laju kecepatan air mengalir sebesar 2,50 m/s, sedangkan putaran poros kincir sebesar 79,78 rpm, torsi rata-rata pada poros 58,98 Nm, maka energi listrik dihasilkan sebesar 510,67 W. Sehingga diperoleh hasil kinerja dari kincir air model kanal, dari hasil analisis menunjukkan hasil uji coba yang terbaik (Jamlay, Sule, & Hasan, 2016) (Syafriyudin, Mujiman, & Atmoko, 2018).…”

Purpose: The potential of alternative energy that is quite realistic can be used as one of the studies in new and renewable energy. such as the flow of irrigation water and solar energy that is always there, in the territory of Indonesia. The purpose of community service, namely the introduction of hybrid pico-hydro, is used for street lights, around the neighborhood. Method: This community service, utilizing irrigation flows to create a small-scale power generation system is named (pico-hydro). To increase the output power capacity, a hybrid system is made, namely picohydro (Ph) and solar panels so that charging the battery is faster so that the power is greater. Limitation: The picohydro generator, equipped with a water canals, aims to raise the water level and focus the flow into the mill. Result: The test results on pico-hydro generate a voltage on a DC generator of 13.2V and a current of 2.3A. While the solar panel generates an output voltage of 13.43V and a current of 2.23A. Contribution: The conclusion is that the higher the rotation of the waterwheel, the voltage and current of the generator will follow up. As well as solar panels the getting hotter, the sun's light increases, the voltage and current increase. Keywords: 1. Picco-hydro 2. solar panels 3. water canals 4. batteries

A waterwheel is a mechanical device in the form of a wheel with blades (bucket or vane) around the edges which are placed on the shaft. horizontally. The waterwheel is a simple tool whose purpose is to convert motion energy into electrical energy. In the design of the waterwheel, the type and dimensions of the waterwheel depend on the location of the wheel, the height of the water fall and the available water capacity. So that in order to obtain optimal efficiency, the design of a waterwheel that operates at a particular location will have a speciLic design, both in the form of type and dimensions that are different from other locations. The purpose of this study was to determine the maximum power, maximum torque and maximum efLiciency that produced a bamboo water wheel with 6 bamboo plate blades. In this study, the data produced is experimental data with the height of the water hitting the blades of 15 cm, 20 cm, 25 cm, 30 cm, and 35 cm and the number of blades is 6 pieces. The results obtained, the maximum power is 7.61 and is found in the variation of water height hitting 15 cm, the maximum torque is 3.71 and there is a variation in water height hitting 15 cm and the maximum efLiciency that can be produced by the bamboo water wheel is 47.67% and found in variations in water height that hit the blade 15 cm.
