The biogas digesters  are  used to produce  methane  gas  and  the designs  of  the  digesters  are commonly bigger in size and have concentration  pressure  gas  at some area such as  at the  edge of  the tank. The  effect  of  concentrated pressure  at the edge of  the biogas digester  tank  will cause leakage.  To  produce  and  collect  the  methane  gas,  this biogas digester design is suitable to use at home and it is portable. So, based on the objective of this project is which to help them, a biogas digester is designed by  considering the ergonomic factors for the usage of people. After the design process is completed, it is needed  to  be  transform  into the  real  product.  The  materials used  to  fabricate  this product  are  round  hollow  steel,  square  hollow  steel,  sheet  mild  steel  and  wood.  The processes  involved  are  welding, rolling, and  grinding, fastening  and  using  glue  to assemble all the parts 0aEngineering design 0aBiogas 0aRenewable energy sources
