Abstract

The Petroleum consumption tends to increase from year to year. From this threat, energy experts estimate, that fossil fuels will run out at a certain time consumed. Diesel fuel is the fuel used by fishermen to turn on the generator set at sea. However, the presence of diesel fuel is currently limited and expensive. Besides that, diesel fuel can cause carbon emissions, and the resulting emissions include SOx, NOx, CO, HC, and particulate dust. For this time, the solution there is to replace diesel with biodiesel. The existence of biodiesel is not an appropriate solution because the prices are not much different from the solar. So that required an appropriate solution to replace fuel oil, like diesel fuel. On the other hand, sea water is a mixture of 96.5% pure water and 3.5% other materials such as salts and dissolved gases. Basically, the sea water contains a compound of high NaCl and by H₂O is decomposed into Na ⁺ and Cl^-. With the existance of free particles, it can generate electricity. The emergence of electric current by the free charge can be used as a source of electrical energy that is cheap and environmentally friendly with  method voltaic cells. Tues voltaic can convert chemical energy arising from the reaction of Na + and Cl-into electrical energy. Therefore, the authors provide a solution that named is "SEACELL (Sea Water Electro Chemical Cell): Utilization of Electrolyte of Sea Water Being Renewable Sources of Energy Electrical as change Generator Set  to Lighting on Sampan". Design SEACELL made with an open system for the ions of sea water keep flowing during operation SEACELL. How it works SEACELL is when the sea water entering and flowing into the SEACELL, ion of the salt NaCl terkadung in sea water breaks down into Na + and Cl-so resulting the anode and cathode reaction. Negative ions from the salt will oxidize Pb electrode, causing a potential difference between electrode Pb with NaCl solution. That's the thing that causes an electrical current. Voltage generated from SEACELL theoretically capable of 15 volts per 1 kg of sea water.
