Abstract :
This study aims to convert heat energy into electrical energy by using a thermoelectric generator. Thermoelectric generator can generate electricity when there are temperature difference between the two sides. The heat source used comes from the wall of biomass stove. This system uses 4 thermoelectric modules in series and uses a variety of fuels, namely coffee bean husks, cocoa bean husks, and rice husks. The results of the research on this system produced the highest power of 0.5575 W with a resistance of 10? on the burning of coffee bean husks. By using the charger method, the electric power generated can be increased up to 3 W.
