The current availability of electrical energy is not proportional to the large demand. This emphasizes the importance of saving electrical energy. To replace fossil fuel power plants that cannot be renewed. So Microbial Fuel Cells (MFC) is used, which is a technology that is able to convert chemical energy from organic matter into electrical energy through the process of oxidation and metabolism of anaerobic bacteria in electroactive biofilms at the anode. This study aims to determine the production of bioelectricity with Microbial Fuel Cell using consortium thermophilic bacteria on TMM substrate. This research was conducted in November 2023 in the microbiology laboratory, FMIPA, UNP. Data analysis was carried out descriptively by displaying images and graphs. Observation of the development of SSA 16 thermophilic bacteria was carried out for 24 hours by checking the voltage once every 2 hours. And the highest voltage result was 749 mv at the 10th hour of measurement.

Biofuel is a potentially renewable alternative fuel in Indonesia. Bioethanol is one example of the most commonly used biofuel. Microorganisms of thermophilic bacteria are known to contribute to the production of bioethanol. Thermophilic bacteria are efficient against high temperature conditions so as to minimize contamination. Production of bioethanol can also use joint culture (consortium). Bioethanol production using a microbial biculture consortium is known to significantly increase the level of bioethanol production. The purpose of this study was to determine the compatibility and to determine the optimum potential of the thermophilic bacterial biculture consortium of Sapan Sungai Aro hot water for bioethanol production. This research is a type of descriptive research. To test the cooperation between consortium isolates of thermophilic bacteria producing bioethanol, a compatibility test was carried out using the disk diffusion method. Then the consortium isolates were fermented in liquid TMM (Thermophilic Minimum Media) medium, the bioethanol content was measured after distillation using a pycnometer. The results of the bacterial compatibility test showed that there was one pair of isolates that were not compatible, namely SSA 8 & SSA 14 due to the presence of a clear zone. On research results. The production of bioethanol by a consortium of thermophilic bacteria gives more optimal results compared to a single isolate. The best thermophilic bacterial biculture consortium from the Sapan Sungai Aro hot spring in producing biofuels is SSA 14 & SSA 16 which is 3.009%.

This study aims to isolate and characterize bacteria that live in hot springs on Bangka Island. The research methods used include bacterial isolation; morphological characterization, Gram group determination and biochemical tests; identification; and thermophilic bacteria temperature resistance test. Hot water samples were obtained from 2 locations, namely Pemali Village and Permis Village. The hot water temperature range at both locations is between 38ºC to 52ºC. The results showed that 22 pure isolates were consisting of 9 isolates from Permis Village and 13 isolates from Pemali Village. In conclusion, the characterization results showed that all bacterial isolates were gram-negative bacteria with various biochemical characteristics. Keywords: Thermophilic Bacteria, Non-Volcanic, Bangka Island
