Energy conversion in compliance of energy self-sufficient village program. case study: Jarak village

The Energy Self-Sufficient Village (ESSV) is one of the main programs from Goverment of Indonesia (GoI) initiated in 2007 and addressed to improve the capability of rural areas to meet the local energy demand from renewable energy. The fulfillment of 60% energy demand is required in ESSV and the source of the energy must be renewable energy. Jarak Village has potentialas to be developed as an ESSV since it has 237 cattles generated manure waste can be converted into biogas. However, the actual conditions showed that the utilization of manure waste as source of biogas is only 14% or about 124,2 kWh covering the energy demand from 40 households. The estimation of the total cattle available in the village can actually covers up to 62% energy demand. The existing numbers of cows generate 82.8 m³ biogas equivalents to 124,2 kWh. Nevertheless, only 124,2 kWh 14% has been consumed by 40 households. It indicates that the consumption of biogas is not optimal. Therefore, the study purposes to evaluate and to estimate the capability of the village to meet the criteria of ESV. With the assumption that there is population growth 0.01%, the criteria of ESV can be fulfilled in 2014. The energy supply of ESV in 2014 is 62%. It indicates that the Jarak Village can actually meet the criteria of ESV in 2014.
