Abstract
Pelton turbine is an engine that facilitates continuous power as a wheel or a
rotor continually turns due to the pressure of fast moving water through the bucket,
where a bucket receives water from the surging nozzle. The objective of this research
was to investigate the highest efficiency among different types of pelton turbine
through the modification of bucket volume, bucket angle attack. The experiment was
conducted at Energy Conversion Laboratory of Sebelas Maret University. The
comparative study among the different parameters shows that the value of maximum
efficiency was 19.58%, which was obtained at +15% bucket size and 92o angle of
attack. It was gained likely due to the collision produced by the jet water in the
middle of the bucket, in which the water loading occupied the large area on the
surface of the bucket and promoted the increasing speed. It is expected that the result
on the appropriate size and angle attack of bucket of this experiment can be
manufactured in the future or develop it for achieving maximum pelton turbine
