Abstract

Along with the increasing human population, the use of fossil energy such as oil also increases. While fossil energy is one of the largest contributors to carbon emissions that can cause climate change. One thing that can be done to control climate change is to switch to the use of renewable energy. In the research conducted, turbine blades with a vertical axis were made using carbon fiber composites with different number of blades, namely with 4, 6 and 8 blades. The testing process is carried out with the wind speed of 4; 4.5; and 5 m/s for each turbine with different number of blades. As a wind direction, the researchers used a wind tunnel made of acrylic and pipes as the leg frame. The results of this study are the highest output power achieved by the turbine blades with 4 blades at a wind speed of 5 meters per second with 5,216 watts. While the lowest output power is in the turbine blades with 8 blades at a wind speed of 4 meters per second with a power value of 0.288 W. The turbine with the number of blades 8 has a fairly low output energy than turbines with 4 and 6 blades. The highest efficiency of wind turbine use is achieved by a turbine with a number of 4 blades with a maximum efficiency value of 95,07% and the lowest efficiency is found in a wind turbine with a number of blades. 8 with a maximum percentage of 6,07%.
