The primary problem in producing biogas is mostly gas and other gas, such as hydrogen gas surplus oxygen. The gas hydrogen sulfide Nitrogen gas and water vapor, hydrogen sulfide gas by only that morning and could not be applied directly in the process of combustion in the engine, because it will cause corrosion of engine deterioration occurs. Acid rain has occurred and can affect health. This research study focusing on a comparison of the suction gas volume hydrogen sulfide removal lining using titanium dioxide. Coal and steel, kamman
