Abstract

Abstract. Screw turbine was developed as alternative micro-hydro power plants. Its working principle is to use the river or irrigation with low discharge. The water flows into the turbine will drive the blades of screw turbine to rotate. Rotation of screw turbine will be forwarded to generator for converted into electrical energy. In this paper we will focus on the manufacturing process for small -scale of screw turbine to generate electricity voltage. Manufacturing process of screw turbine component as micro-hydro power plant consists of two components such as mechanical and electrical components. Mechanical components consist of a screw turbine, home of turbine screw, shaft of turbine and bearings. The manufacturing process includes the cutting plate process, drawing process and joining. Electrical component is a generator with the rotor (magnets) and the stator (coil) and then assembly the mechanical and electrical components. After the assembled all component then followed performance testing of the screw turbine and generator. From the manufacturing process of screw turbine and generator are obtained the results of rotation and electric voltage.
