“…(1) dengan Q adalah debit air (m 3 /s), H adalah ketinggian air (m), g adalah gravitasi dan adalah densitas air. Nilai Q sebesar 1 liter/s, nilai H = 1 m, nilai = 1000 kg/m, nilai g = 10 m/s 2 , dan efisiensi maksimum kincir air overshot sebesar 85% [22]. Hasil perhitungan diperoleh bahwa energi potensial air yang tersedia adalah sebesar 847 Watt.…”

Inovasi pengembangan Pembangkit Listrik Tenaga Mikro Hidro (PLTMH) terus dikembangkan mengingat kebutuhan akan energi listrik terus meningkat. Hal ini perlu didukung adanya media pembelajaran untuk mencari solusi alternatif permasalahan dalam mengatasi kebutuhan energi tersebut. Penelitian ini mendesain dan mengembangkan pembuatan PLTMH dengan back flow water system. Implementasi sistem berupa prototipe yang dapat digunakan sebagai media pembelajaran mahasiswa dan alat uji energi alternatif hidro. Metode perancangan dan manufaktur menggunakan metode Pahl & Beitz dan pengujian menggunakan metode eksperimen dengan cara pengamatan dan pencatatan data-data yang ditunjukkan pada alat ukur. Pengujian dilakukan dua tahap, pengujian pertama pada putaran kincir dan transmisi, pengujian kedua pada putaran dinamo dan voltase. Hasil pengujian menunjukkan bahwa sistem yang dirancang memiliki unjuk kerja yang baik.

“…Based on hypotheses Yah et al, [12] and Warjito et al, [6], the 1 h/hup is considered realistic to be applied in USWW for the run of river conditions. Then, Warjito et al, [13] adopted the Pelton turbine blade number (z) equation for the USWW by computational fluid dynamics (CFD) method. Warjito et al, [13] used the boundary condition is 1 h/hup, adaptation of the z equation for USWW yields 8, hence it is considered unreasonable for larger scales.…”

The computational fluid dynamics (CFD) method is often used for undershot waterwheel (USWW) studies. The CFD method is a suitable solution for investigating physical flow phenomena on USWW so that its energy conversion process can be appropriately understood. The transient simulation is necessary to study the flow of physical phenomena. However, there is no recommendation for the transient approach for USWW. The boundary conditions for the transient approach often used for rotating case objects is a moving mesh. Therefore, this study investigates moving mesh as a USSW transient approach to predict its performance. Based on the results, the average deviation from simulation results to experimental data of torque is 22.1%, mechanical power is 5.75%, and efficiency is 5.75%. The average deviation reading of torque is 2.93 N·m (not a significant difference), mechanical power is 0.47 W, and efficiency is 1.19%. Further, the curve data simulation results to experimental data show a similar pattern, expressed by exponential for torque and polynomial for mechanical power and efficiency. Thus, a transient approach using the moving mesh feature is recommended for the USWW case; because the data pattern and reading deviation are reasonable.
