ABSTRACT
Overtime, technology has grown, and the world is entering a modern era. In
this modern era, human needs are increasing, especially in electricity Most of the
existing power plants still use fossil fuels and only utilize renewable energy by 11%.
However, fossil fuels are not very environmentally friendly, and nor good human
health. On the other hand, Indonesia is an archipelagic country with 2/3 of its area
is water. Therefore, the use of renewable energy needs to be maximized. Ocean
Thermal Energy Conversion (OTEC) is a type of renewable energy that has great
potential considering that Indonesia is a tropical country. In this study, the
implementation design of the Goswami Cycle was carried out at the proposed
OTEC power plant in the Flores Sea using EBSILON Professional software. The
Flores Sea has an average surface temperature of 29.14?C and an average deep-sea
temperature of 4.58?C which was obtained with the help of Ocean Data View
software. From the Goswami cycle simulation, it is known that the use of a 95%-
5% ammonia-water mixture as a working fluid with a turbine inlet pressure of about
11.8 bar, an absorber output temperature of 6°C, and a rectifier output temperature
of 37°C produces the highest efficiency, which is 23.88%. Variations in turbine
inlet pressure affect the amount of enthalpy at the turbine inlet side and the vapor
flow rate that enters the turbine. Meanwhile, variations in the output temperature of
the absorber and rectifier have more influence on the amount of mass flow that is
divided into the two outlets of the rectifier. The development of OTEC is considered
economically unfeasible for a small capacity, but quite feasible for 1 MW size by
seeing the value of BCR, NPV, IRR, DPP, and LCOE.
