In line with the developments at various sectors of both industrial and non-industrial into one of the effects of waste production keep increasing daily, while demand for energy is progressively increasing and also energy resources become more limited, mainly from burning fossil fuels that have been the only resources. Therefore, we need another energy source that is capable of being an alternative to overcome the energy crisis and reduce the impact of the waste which is keep increasingly over day. One of the alternative energy source that is being developed is Biogas. Yet people nowadays still rare to harness this energy, due to the expensive cost as well as the way of making that is not easy and also considering that the condition of the ambient temperature, the PH levels of the water, construction structure. Making of biogas digester using basic materials has main aim that to reduce corrosion of concrete digester from the surrounding environment is high enough changes. Digester can accommodate a large amount of garbage, and can produce gases such as methane that can be used as household fuel.Teknik ElektroElektronikaEngineering and Allied Operations (Teknik dan Ilmu yang Berkaitan)Social Problems and Services; Associations (Permasalahan Sosial, Layanan Sosial; Asosiasi)Ilmu Komputer, Ilmu Informasi, Karya UmumThesis
