Indonesia is an archipelagic country having 13,466 islands extending 5,120 km from East to West and 1,760 km from North to South Indonesia. In small or outermost islands, supplying fresh water and electricity for public are still a serious problem and must be addressed by the government. As Indonesia is an equatorial country located at latitudes less than 20 degrees covered by 77 % ocean, thousand islands, strain and many difference of topography, Ocean Thermal Energy Conversion (OTEC) is very compatible built in Indonesian. This paper discussed the potential areas of 100 kW OTEC to be applied in Indonesia. The simulation results found that Indonesia was high potential for application of OTEC in which electricity and fresh water produced by OTEC are cheaper than the current price market.

Of the topics which have recently been taken into consideration are the environmental contamination and its fatal effects on earth. A considerable percentage of pollutant gases are made by the ships' diesel motors, so their manufacturers in adapting them have been impelled to take some implementations for decreasing these compositions. International maritime organization (IMO) has also put a serious stress on this matter. Sulphur is one of these greenhouse gases. More than 80 percent of SO diffusion rests on the fuels' combustion. The environmental regulations have strictly focused on minimizing these pollutants. This paper is aimed at examining Sulphur ingredients and its fatal effects, desulphurizing methods, IMO's related regulations, their effects on the ships and the ways of improving them. Some solutions have also been rendered to decrease the usage of Sulphur.
