Abstract: “This paper aims to explain a project which designed a system to compress and store the biogas in such a way that it will be suitable for cooking gas in rural communities, especially in Ngentak Village, Poncosari, Bantul, DIY Province in Indonesia. After water content and CO2 have been removed from biogas methane from digester by Diethylen Glycol and Natrium Hydroxide (NaOH), water has to be reduced until 2.5 ml by 15 ml of glycol content and NaOH 30% to reduce 1.34% of CO2 content and 94.59% of gas methane. In addition, biogas compression and bottling process consist of different steps such as biogas purification (H2O and CO2 removal unit), compression and bottling. As a result, this study has succeeded in compressing biogas into 8,78 lbs and LPG cylinder reaching maximum level in pressure gauge.”
