Abstract

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.

Abstract

In Indonesia, the population growth rate is high and requires rapid and sustainable improvements in the agricultural sector. Improvements in the agricultural sector require various supporting facilities, namely agricultural tools, fertilizers, chemicals including pesticides. Pesticides are chemicals or mixtures of several chemicals that are used to control or eradicate plant pest organisms. Specific uses are an inseparable part of the agricultural system. Pesticides are used as a preventive measure to control pests/diseases. The research carried out included testing on soil samples, testing bacterial turbidity, and testing inhibition zones using antibiotics. This research is descriptive research. This research was carried out from March to June 2023, at the Research Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Padang State University. From the research carried out on soil sample tests, what was observed was the color, shape, height and edges of each different type of bacterial colony. The turbidity test was obtained in accordance with Macfarlan standards. Then the zone inhibition test uses antibiotics which use positive, negative and spectrum antibiotics. From the table of inhibition zones that are formed, it can be seen that in each bacterial colony, each antibiotic works according to the type of antibiotic, positive antibiotics inhibit the growth of gram-positive bacteria and negative antibiotics inhibit the growth of gram-negative bacterial colonies, while spectrum antibiotics can inhibit the growth of gram-positive bacteria and bacteria. gram negative.
