Abstract

The potentials of energy from manure waste was calculated in this study aiming to develop biogas utilization in a rural area. The calculation was conducted based on the result from clustering the non-biogas farmer households which cannot afford individual anaerobic digester (AD). Spatial cluster analysis (SCA) and superimposed technique were used to determine the size of the groups and the location of ADs respectively. Value from SCA showed that the village’s settlement pattern is clustered feasible to apply communal AD for rural biogas development. Meanwhile, a superimposed technique using 3 parameters which are land availability, cow ownership, and topography, generates 43 clusters of farmer households that can supply biogas for cooking. The energy production is estimated at 8.96-39.68 m3/day/household, while the energy demand is approximately 0.65-3.48 m3/day/household. The calculation shows that there is remaining biogas that can be distributed to non-biogas farmer households. Using SCA, 75 non-biogas farmer households were identified to be potentially supplied by biogas. The total energy demand for both biogas and non-biogas farmers households is 2,147.34 MJ/day, while the total potential energy generation from all ADs is 24,560.64 MJ/day indicating a low biogas utilization rate which is only 8.7%. The percentage shows that biogas utilization for an energy source in Dusun Dresel can be more developed by enhancing the distribution network or by converting it into electricity to support rural energy security.

Abstract

According to NAWACITA (Indonesia’s 9 years long plans), frontier region has priority to be developed because it is characterized as underdeveloped region which has inadequate infrastructures and underprivileged families. The study aims to assess the condition of livelihood assets in the frontier region. Livelihood assets are assets that local people use for living. This research employed descriptive statistical analysis which the data was derived from questionnaire, interview, and observation. Variables to assess the condition of assets were from financial livelihood asset, human asset, social asses, and natural asses. The result is drawn on a pie chart and allowed assets to clearly identify. The results stated that the highest asset is from human asset i.e. sub variable local ecological knowledge ( 85%) which is the knowledge of farming. Therefore, the lowest asset also from human assets i.e. access for education and additional skills. Local people are having difficulties to access the education center just like in Hillbilly Merau and Serangkang because the way to reach there still rocky and rough (undeveloped). Local skills in the village of Entikong are not fully mastered yet but people take special attention in the field of crafts.
