Abstract :
With population growth and economic growth, the need for electrical
energy is also increasing. In Indonesia, there are still many uses of conventional
energy which will soon run out, so alternative energy sources are needed, one of
which is water. This study aims to determine the effect of blade bending angle on
the performance of waterwheel with overshot type.
This research is an experimental type of research, the waterwheel used is
the oveshot type with blade bending angles of 180o, 150o, and 120o. This
research was conducted on the disposal of fish pond water. The results show that
the highest output power at a blade bending angle of 120o produces the highest
generator output power of 10.51 Watt at a lamp load of 10 Watt. Whereas. The
highest efficiency at 120o blade bending angle is 21.89%. Maximum torque at
180o blade bending angle is 4.32 Nm at 30 watt lamp load.
