Abstract :
Indonesia is a country that has very abundant energy resources, one of
which is a source of wind energy. The potential of wind energy in Indonesia is
quite adequate, because the average wind speed ranges from 3.5 - 7 m / s.
Whereas according to Jogja BMKG in 2016 the average wind speed in
Yogyakarta was 2.5 m / s. One of the uses of wind energy is the use of wind
turbines that are widely used for agricultural needs, such as to drive pumps for
irrigation purposes, as well as the need for energy that is as a wind energy power
plant. This study aims to determine how the process of making a mini prototype
Vertical Axis Wind Turbine Helical-Blade and can determine the results of the
mini prototype VAWT.
In the mini VAWT manufacturing process using conventional methods of
hand lay-up and laser cutting. In the process of making prototypes, several
materials including styrofoam, polycrylic resin, fiber clooth, carbon tube and
multiplex are needed.
In the mini VAWT manufacturing process it starts with design data then
preparation of materials and tools used. In the manufacturing process requires a
laser cutting process to make foam cut malls and rotor arms then in the process of
making rotor blades need a hand lay-up method. If all parts have been completed
then the next process is assembly to produce a Mini Vertical Axis Win Turbine
Helical-Blade.
