Carbon dioxide from the biogas resulted in vinasse fermentation should be treated. One of the methods that could reduce carbon dioxide was the adsorption process. A chemical and physical process could modify the characteristic of carbon and obtain activated carbon as an adsorbent. Chemical activation using H2SO4 ranged from 5% to 30%, and physical activation using pyrolysis at 400oC for 3 hours. The adsorption process was done by inserting 98.68% synthetic CO2 range from 0.002 to 0.0058 L/min from the bottom of the adsorption column with 5 cm in diameter and 30 cm in height. Chemical activation with 25% H2SO4 achieved the best result. Characteristics of activated carbon were analyzed using proximate and BET analysis, where the ash content was 3.93%, fixed carbon 80.015, the surface area was 5992.65 m2/gr with a total pore volume of 39.4620 cc/gr, and pore radius average was 2.6072 Å. The value of CO2 adsorbed was 99.939% at a gas rate of 0.0022 L/min.
