Abstract
Several types of renewable energy have been developed, such as solar energy, biomass, hydro energy, geothermal, and wind energy. Wind energy is an up-and-coming alternative and renewable energy. Wind energy is more environmentally friendly than available energy sources and has more accessible operational and maintenance costs. Indonesia has a relatively small natural wind energy potential because the wind speed in Indonesia is on average 3-6 m/s due to its location. Geographically, it is located in the equatorial area, especially the Muara Enim area, South Sumatra. This study aims to design a prototype the four-blade darrieus type vertical axis wind turbine (VAWT) needed for the utilization of wind energy which is used for Coffee Shop electricity needs at the Jamik Bukit Asam Tanjung Enim Mosque complex, South Sumatra, with the conclusion that the wind turbine, wind turbine rotation, the magnitude of the output voltage and The current generated significantly affects the wind speed in the area.
Highlights
One of the rapidly growing renewable energies in the world today is wind energy [1]
Wind energy has long been known and used by humans, for example, for power generation, but wind energy in the Indonesian region is classified as low wind speed
One of them is the manufacture of wind turbines, which will later help generate electricity and meet the community's electricity needs [3]
Summary
One of the rapidly growing renewable energies in the world today is wind energy [1]. Wind energy has long been known and used by humans, for example, for power generation, but wind energy in the Indonesian region is classified as low wind speed. Wind potential in Indonesia is available almost all year round, making it possible to develop small-scale power generation systems [2]. The quality and quantity of wind have low speed where wind energy engineering is needed because of its significant and efficient potential in the future [7][25]. Effective technology is needed to increase the possibility of using wind energy at low wind speeds [10]. It is necessary to develop a type of wind turbine suitable for use in areas with low wind speeds. Modification of the rotor blades is one option to optimize energy extraction carried out by a Vertical Axis Wind Turbine (VAWT) [12][15][19]. A study with turbine analysis with four blades Type Darrieus was conducted for the coffee shop electricity needs in the Jamik Bukit Asam Mosque complex, Tanjung Enim, South Sumatra
