Energy is an important need for humans, especially electrical energy. Ocean wave energy is alternative energy generated through the effects of air pressure movement due to fluctuations in wave movement. With these waves, the mechanical energy of the waves can be converted into electrical energy with a translator. The size of the electric current produced at the ends of the emf is influenced by 3 factors, namely the number of turns, the strength of the magnetic field, and the speed of magnetic movement or the speed of change in magnetic lines of force (magnetic flux). This research focuses on the importance of laboratory-scale research to determine the linear generator analysis for wave energy conversion. The purpose of this study to determine the output, among others; (1) Linear Generator Generating Power, (2) Linear Generator Voltage, (3) Linear Generator Current, (4) Linear Generator Power, (5) Linear Generator Efficiency.

Based on this research, it can be concluded (1) The performance obtained in the linear generator test in each different variation, the results obtained on a generator with a wire diameter of 1 mm obtained an efficiency of 8.18%, on a generator with a wire diameter of 0.5 mm the efficiency results of 5.74%, and on a generator with a wire diameter of 0.2 mm the efficiency results are 3.06%. The size of the coil wire diameter is quite influential on changes in voltage and current including power. Where as the voltage increases, the current also increases for each diameter variation. (2) Obtained a linear generator with a coil wire diameter of 1 mm with effective results, getting a voltage of 4.09 volts, getting a current of 17.49 mA (0.01749 Ampere) and getting a power of 0.0715 watts with an efficiency value 8.05%.

Keywords: Alternative Energy, Linear Permanent Magnet Generator, Variation of coil wire diameter.
