2020, Test Engineering and Management

Indonesia has the most significant energy consumption in the Southeast Asian region and many rivers as a potential source of energy for hydroelectric power plants so that the plants can be utilized to help people in mountainous areas that have not been reached by government electricity. This study used a vertical shaft kinetic turbine installation. Water debit is one of the variables giving effect on the turbine rotation, turbine tangential force, torque value, turbine power, and kinetic turbine efficiency. This research employed laboratory-scale experimental methods. In this study, three variations of flow rate were given, namely 0.0056 m 3 /s, 0.0067 m 3 /s, and 0.0078 m 3 /s. Each flow ratewas tested with turbine rotation variations of 10, 30, 50, 70, and 90 rpm. The results of the study, the calculation, and the discussionconcluded that the flow rate had an effect on the kinetic turbine performance. Based on calculations using equations 1, 2, and 4, the maximum torque of the turbine flow occurred at a flow rate of 0.0078 m 3 /s, with a torque value of 1.326 Nm, and the maximum turbine power occurred ata flow rate of 0.0078 m 3 /s, with a power value of 4.508 Watts. Meanwhile, the maximum turbine efficiency occurred at a flow rate of 0.0078 m 3 /s, with an efficiency value of 28.457%.
