The Fishermen are a type of livelihood that is mostly carried out by Indonesians who live on the coast. In the country with the largest long coast in the world, Fishermen should have good welfare and a healthy lifestyle. But in fact, most of the traditional fishermen in Indonesia have not felt it. They still carry out fishing activities in an inefficient way, due they only follow the work patterns that have been done by their predecessors, far from the touch of technological advances that have an impact on high operational and maintenance costs while searching fish. The boundary of this research is to calculate the average cost of energy from boat lighting to energy sources using the homer simulation method. The purpose of this study is to compare the energy consumption generated by electric boats (e-Boat) and conventional fishing boat. Mercury lighting technology on the conventional fishing boat compared to LED electric boat lamps with the same level of luminance, 75% lower energy consumption, and Levelized Cost of Energy (LCoE) 11% lower. Thus, energy is more efficient, clean, and there is a new, more effective pattern.
