    Energy is a critical component of development and one of the most significant resources. Our country now has a limited supply of energy to meet the needs of society in order to complete various duties. Biogas is a gas that is created when organic matter is broken down in the absence of oxygen. It's made from locally sourced raw materials and repurposed garbage. So, instead of utilizing charcoal or other energy sources, the problem of energy scarcity can be solved by employing biogas energy. This is especially true for individuals who live in rural areas. The goal of this research is to create biogas from animal dung as a domestic alternative energy source. Cow dang is the undigested plant stuff that passes through the cow's gut. It has a dark brown color and a high ammonia content. The manufacturing method consists of four steps: hydrolysis, acidification, acetogineses and methane creation, with the effect of temperature, retention duration, and cow waste potential on biogas production being studied. We have done four experiments experiment1, experiment2, experiment3 and experiment4, from those experiment we get the best result 0.21L, 0.2L, 0.19L and 0.2L amount of biogas respectively. Therefore we compare four experiment and the best biogas product is from experiment one.
