Abstract

The use of hydrokinetic energy as a renewable alternative energy is experiencing rapid
development along with the increasing energy demand in the world. One of the hydrokinetic
energy sources is from the energy of water flow. The energy can be used as electricity
generation by using hydrokinetic turbines. The working principle of a hydro-kinetic turbine
in a hydro power plant that is utilizing and relying on water kinetic energy as its energy
source in converting potential energy and kinetic energy of water flow into mechanical
energy. Water Power Plants have the main components, Turbines and Generators. Darrieus
turbine is a type of Vertical Axis hydrokinetic turbine that is often used in hydroelectric
power plants. Therefore, this will be done making prototypes of Water Power Plants which
include prototype design, making fluid vessels, and making Darrieus turbines using blades
with type NACA 0018. In performance test of the Darrieus Turbine, 5 variations of fluid flow
velocity that is 0.77 m/s, 0.89 m/s, 0.99 m/s, 1.17 m/s, and 1.25 m/s are used. The variations
in the number of turbine blades are: 2 pieces, 3 pieces and 4 pieces with 0º, 10º, and 15º angle
of attack. The Darrieus Turbine test results obtained the highest rotation at 195.17 rpm with a
turbine mounted 2 blades with an angle of 0?, the power generated at the rotation is 0.18
Watt. Optimal results in the test are obtained in the tubing which is installed 4 blades,
because when the speed of 0.77 m / s the turbine is able to do self-starting at the attack angle
of 0º, 10º, and 15º, the optimal power obtained in the 4 blade turbine is 0.1 Watt
