In generating
electricity process, the ORC system was compared with a Kalina cycle
in term of efficiency. Guzovic et al. [16] studied the geothermal energy
to power plant in Croatia. The high temperature hot spring at 175°C
was supplied to binary system which of organic rankine cycle and
kalina cycle. The simulated results shown the ORC cycle had a higher
thermal efficiency and energy efficiency compared with the kalina
cycle. Moreover, a low potential geothermal at hot water temperature
