Abstract

Waterwheel is a means to convert water energy into mechanical energy in the form of torque at the wheel shaft. The waterwheel works with a large flow and utilizes a high waterfall. Currently waterwheels still have a small efficiency when compared to the existing water turbines. Therefore, further research is still needed to increase the rotation (rpm), mechanical power and efficiency of the waterwheel. The purpose of this study was to determine the performance of the nozzle angle variation with the natural flow of the waterwheel. In this study, using a breastshot type waterwheel with 12 blades with a water flow of 12 liters / second. By using the analysis, the results show that the mechanical data and the efficiency of the wheel are affected by the flow of water hitting the blade using a nozzle. The tilt angle of the nozzle is very important, the steeper the nozzle, the faster the water flow will hit the wheel blade. In the rotation test (rpm), the highest mechanical power and efficiency at the use of a nozzle with an angle of (25°) is at 76 rpm, which is 29 Watts and the lowest power is at 19 rpm, which is 13 Watts at a discharge of 12 liter / second. Whereas the natural flow is at the rotation 76 rpm which is equal to 7.11. Watt and the lowest power at the rotation 19 rpm namely 4 Watt at a discharge of 12 liter / second.

Abstract

Ketersediaan air merupakan permasalahan utama pada sebagian wilayah di Indonesia. Terdapat beberapa daerah khususnya di pedesaan Gondosuli - Probolinggo yang hanya dapat memaksimalkan penggunaan air secara maksimal saat musim hujan. Disamping itu, air memiliki peran penting dalam masyarakat yang sebagian besar berprofesi sebagai petani. Air adalah salah satu faktor utama yang mempengaruhi jumlah produksi lahan pertanian dan perikanan. Pada permasalahan tersebut dibutuhkan ketersedian air yang berkelanjutan, sehingga dapat mencukupi kebutuhan produksi sehari-hari. Oleh karena itu, diperlukan penggunaan hydraulic ram pump yang dapat bekerja dengan bantuan tenaga surya tanpa memakai energi listrik. Prinsip pengoperasian pompa hydram dengan mengubah energi kinetik aliran air menjadi tekanan dinamis, dan sebagai hasilnya palu air dibuat untuk menciptakan tekanan tinggi di pipa udara. Dengan adanya desain kontruksi Hydraulic Ram Pump System diharapkan dapat mengatasi ketersediaan air secara berkelanjutan, sehingga produksi di bidang pertanian serta perikanan dapat stabil bahkan meningkat.
