Abstract:
This research aimed to produce biogas from banana residues and cow dung using fermentation technology. The biogas production setup consisted of a plastic barrel serving as the digester, a storage tube for gas collection, an inlet and outlet pipe, and control valves to manage the flow. Banana residues, including stems and leaves, were cut into small pieces to enhance decomposition, yielding a total of 5.9 kg. Cow dung, weighing 4.4 kg, was added as a substrate to support microbial growth, along with 0.5 kg of active bacteria to accelerate anaerobic fermentation. To create an optimal fermentation environment, water was added in equal parts (1:1 ratio of wastewater to natural water), achieving a solid-to-water ratio of 1:1.5.Biogas production was closely monitored over a 52-day period. The process yielded promising results, with the highest biogas output recorded on day 18, when the storage tube was fully filled and produced a weak initial flame. By day 30, the storage tube reached full capacity once again, igniting a steady and stronger flame, indicating a high methane concentration suitable for combustion. Based on these findings, the study recommends developing an integrated underground biogas unit, which would improve insulation, maintain steady temperatures, and enhance the efficiency of biogas production, making it more suitable for sustainable energy use in rural settings.
