The utilization of renewable energy in Indonesia is considerably low. To respond this issue, the Indonesian government creates several policies to increase the renewable energy utilization to 23% in 2025. One of several attempts in implementing these policies, the Indonesian government aims to build renewable energy developments, especially on biogas construction to produce energy up to 48 KWh. Biogas practically has already been used by the people in the Village of Wonolelo, Bantul, Yogyakarta since 2015 as fuel for stoves. It signifies that the acceptability of biogas utilization as renewable energy has already begun. Based on this reason, researchers of this study seeks to determine the potential of biogas development based from cow dung as a renewable energy source and also the potential of biogas utilization from cow dung as an effort to improve the economy of the local society in efforts to achieve national energy security, through using mixed methods research. This research found that firstly cow dung has big potentials for renewable energy purposes. These potentials are the utilization of cow dung could produce up to 108 m3 of biogas that is equivalent to 49.68 kg of LPG or equal to 66.96 litres of kerosene; improve biogas utilization up to 26.15% for 3 years and mostly applied for cooking purposes; highly effective for cooking purposes (reaching up to 90%) but relatively low effectiveness for lighting purposes (reach up to 10%); its utilization could be used by the community in the event of a disaster and to support local manufacturers of kitchen appliances because the production of biogas will have increased every year. Secondly, biogas utilization from cow dung could improve the economy of the local society because through the used of biogas, they can save up their money every year with an equivalent of the total income from the district minimum wage up to 16,200,000 IDR; reduce the amount of unemployment in developing biogas utilization and production; and improve energy sufficiency to achieve national energy security.
