Abstract: A trial has been carried out to see the effectiveness of the new form of water turbine blades which is an effort to accommodate as much water as possible to be converted into mechanical energy that is useful for human life. This blade is intended for undershot type waterwheels which are operated in rivers in South Sumatra, which generally have low current speeds. A blade with a vertical wall on the left and right and a gamma angle on the exit section is tested at a flow rate of 0.8 m / s - 2.5 m / sec. This blade shows the ability to accommodate water kinetic energy optimally, where there is a tendency for greater gamma angles, the greater the power generated at the same flow rate.
