Axial turbine is a very unique turbine, that
has been used by water plantation (PLTA) in Indonesia,
which can be found as many as 162 units of the water
plantation per 2021. Axial turbine usually uses natural
energy from water flowing, especially waterfall. The
energy that is extracted from the waterfall is the
potential energy of the water flowing down. Those
energy is the source of power for this turbine to rotate,
and through the rotating shaft, mechanical energy will
be formed. In this paper, the output of an axial turbine
will be analyzed, and the main variable for analyzing
will be pressure drop towards the mechanical energy
created by axial turbine on a lab scale. Tests will be
carried out on a laboratory at Universitas
Tarumanagara (UNTAR) for data to analyze.
