Biogas is a renewable energy source derived from organic material that is anaerobically degraded by bacteria in an oxygen-free environment. The main components of biogas are methane (CH 4 ) and carbon dioxide (CO 2 ). In addition, there are other relatively small amounts of gas, namely nitrogen (N 2 ), hydrogen sulfide (H 2 S) and hydrogen (H 2 ). The quality of biogas that is non-optimal can be improved by separating or eliminating impurity gases, one of which is hydrogen sulfide (H 2 S). Hydrogen sulfide (H 2 S) is a poisonous and odorous gas that causes corrosion, so it needs to be reduced in biogas. Hydrogen sulfide (H 2 S) in biogas can be reduced by adsorption methods using modified natural zeolites. The purpose of this study is to determine the effect of the natural Zn/zeolite impregnation ratio and the effect of the adsorbent calcination temperature on biogas purification and determine the concentration of hydrogen sulfide (H 2 S) from biogas purification. The adsorbent is synthesized with variation: natural Zn/zeolite ratio of 10%, 20%, 30% w / w and calcination temperature of 200°C, 300°C, 400°C. Adsorbents are characterized using X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM). The result of this research show that the optimum adsorption capacity of hydrogen sulfide (H 2 S) in biogas is obtained at a variable ratio of Zn/zeolite natural 20% and calcination temperature of 300°C is 6.36 mg S g adsorbent and H 2 S can be purified or adsorbed up to 99%.
