This study aims to know the effect of differences in grain size variation in fine and coarse bricks in the biogas purification process by reducing carbon dioxide gas levels using the adsorption method, so as to obtain the most suitable size to produce the most optimal purification results. In this research, the biogas purification process uses brick powder as an adsorbent, utilizing the alumina and silica content in bricks to absorb carbon dioxide gas. Testing the purified gas content in biogas using Gas Chromatography - Mass Spectrometry (GCMS). The data processing method used in this study was a factorial design method 2 3 . The variations used in this study were the size of fine and coarse bricks, the purification time variation of 5 minutes and 20 minutes and the flow rate variation was 1 Liter minute −1 and 2 Liter minute −1 . Fine size variation, a flow rate of 1 L Min −1 and a purification time of 20 minutes give the best results with the percentage level of carbon dioxide falling reaching 10.319%.
