Given the rapid population growth and society's dependence on electric power, Indonesia's electricity needs are very large, so all available energy potentials must be optimally used, including low-temperature geothermal sources, which cannot be used as electricity generators because spin turbines cannot. With this, electric power generation technology is needed without requiring any mechanical process to process geothermal energy from low-temperature sources, namely the thermoelectric generator (TEG), an energy conversion technology whose working principle is based on the Seebeck effect, and is still in the development phase to large power generator.an energy conversion technology that working principle is based on the Seebeck Effect and the technology is still in the development stage to become a large-scale power generator. The experiment was carried out by placing the TEG between the heat source and the coolant on the prototype tool, then measuring the time t, the difference between the hot and cold temperatures ?T of the device, and the electric voltage V generated since the tool was operated to determine the performance of the TEG at the beginning of the working process of the tool prototype. The experimental results show that at a temperature of 144,9 ° C with a temperature difference of 114,2 ° C, the TEG module can generate an output voltage of 15,97 V without load, while the TEG module with two 6,8 Ohm loads connected in series at a temperature of 144,9 ° C at a temperature difference of 112,7 ° C can output 9,22 V. From the modelling results, it is known that the temperature increase pattern of the top layer of the TEG’s model is proportional to the temperature increase pattern of the experimental results. The information obtained from the modelling results will be useful for designing large-scale device models.
