Indonesia with a total sea area of almost 8 million km2 seeks to increase inventory of non-living resources. One of which is the energy potential of ocean currents. Due to its specific tectonic environment, Indonesia needs special attention in assessing the capacity of its marine data. Therefore the geosciences of marine research in Indonesia can be said to be still a new thing. The idea of creating electrical energy from seawater has just been applied, which was applied for the first time in Bali, which is referred to as PLTAL (Sea Hydroelectric Power Plant) and stated by conducting research that one unit of power plant can produce up to one megawatt enough to support a village's electricity. However, in reality the power that can be generated ranges from ten kilowatts. This is what makes the application of this power plant still limited to large-scale use, but it is enough if it is used for the use of small currents in one place, for example to turn on lights on the edge of the road. However, it is said that the cause of this phenomenon depends on the seawater content in each region or place, the better the salt content of the sea, the greater the voltage and the electric current generated by the sea water. This system consists of several main circuit parts, namely, voltaic cell circuit, low voltage inverter circuit, and jhoule thief circuit as a voltage amplifier. Overall, this system works to produce electrical energy from sea water through voltaic cells and then with a jhoule thief circuit, the voltage from the voltaic cell voltage will be amplified then raised by the inverter while converting the DC voltage to AC voltage. The container or vessel in this study uses a small plastic jar with a volume size of 1 container. The total number of containers used is 8 containers so that the total volume of sea water as an electrolyte solution used is as much as 8 liters of sea water. Likewise with electrodes installed in cells having the following sizes zinc has a length and width of 12 Cm and 6 Cm as well as copper. Then for charcoal varied in each experiment to review whether charcoal has an influence on the output voltage that will be produced. Variable volume of seawater that will be measured voltage is per each container (1 L, 2 L, 3 L, 4L, 5L, 6 L, 7 L, 8 L). The output voltage is divided into two parts, namely the output DC voltage ie the voltage directly from the cell circuit and the AC voltage output from the inverter. The experimental results are displayed via graphs. From the graph it is clear that the output voltage of the voltaic cell containing two charcoal has the highest voltage followed by one charcoal and the last without charcoal. This can prove that charcoal has an influence on the voltage output produced by voltaic cells because charcoal makes the reduction reaction faster and produces more electrons. Keywords: Inverters, Jhoule Thief, Volta Cells
