Biogas is a gas produced by the decomposition of organic materials involving microorganisms in the anaerobic state. The research focused on obtaining good quality biogas through NaOH and KOH purification by reducing H 2 S and CO 2 levels. The purification of biogass proceeded in a variation of absorbent concentrations 0,05M, 0,1M, 0,15M NaOH and KOH solution. Gas chromatography chose for biogas characterization. Based on TCD detector in gas chromatography, it represented concentration area in percentage (%). The content of biogas for control was 2.14% CO 2 and 0% H 2 S. The Addition of 0.05; 0,1M; 0,15M NaOH produced 1,57%, 1,56% and 2,98% CO 2 respectively. Moreover, the addition of 0.05 M; 0,1M; 0,15M KOH yielded 0.81%, 0,30% and 1,03% CO 2 . The highest of the burning calories was the NaOH 0,15M amount of 66,528 kcal and the lowest of the burning calories was the 0,1M KOH amount of 38,976 kcal.
