Abstract

ABSTRACT Renewable energy is an energy source that is available by nature and can be used continuously. In line with the statement of the International Energy Agency (IEA) which states that renewable energy is energy that comes from natural processes that are continuously replenished. The purpose of this study is to make a wind turbine model combined with the Giromill and Savonius types, to find out the electric current generated at the rotating speed of the different Giromill and Savonius type combination wind turbine models, to determine the turbine power of the Giromill and Savonius combined wind turbine models using different wind speeds. different, knowing the level of efficiency of a wind turbine type combination of gyromill and savonius wind turbines. This combination wind turbine model of the Giromill and Savonius types is a combination of two types of vertical axis wind turbine (VAWT) wind turbines that are designed to be one. The giromill wind turbine has a sweep diameter of 80 cm, a height of 80 cm, and a total of 3 blades with a NACA 0024 airfoil cross-section and a chord of 20 cm. Meanwhile, the Savonius wind turbine has a sweep diameter of 40 cm, a height of 60 cm and has 2 semicircular blades with a blade span diameter of 22 cm, 24 cm and 26 cm. In this study using a ballast load. The research was conducted in the yard of the house and used natural wind and a fanblower. The results of the wind turbine performance research show that the combination wind turbine model of the Giromill and Savonius types with a Savonius blade diameter of 26 cm and a blade span of 26 cm at an average wind speed of 5.3 m/s can produce a maximum rotation of 68.7 rpm. under no-load conditions and the performance of the wind turbine when given a load gets an efficiency of 48.24% and produces a turbine power of 10.7418 watts and a torque of 1.4940 N.m. Keywords: Giromill and Savonius type combination wind turbine, NACA 0024, vertical axis wind turbine (VAWT), efficiency, turbine power, rpm, ratio.
