Based on the Bali RTRW 2009-2029 document, one of the areas that has the potential as a supplier of bio-biomass electricity to meet the energy mix target (0.9MW) is Belimbing Village, which is designated as an agropolitan area because it has fertile land and good irrigation. Belimbing Village has land for the development of EBT biomass without having to open new land or shift the main commodity (food) to energy, namely by utilizing the space between the plantations and their waste, such as coconut as one of the main products of Belimbing Village. According to Leksono (2014), coconut waste (coir, shell, midrib and meat dregs) has a high calorific value to be used as a source of electricity, however, the use of waste needs to be taken into account to ensure stock availability (Bassam, 2011). Biomass renewable energy in Belimbing Village in order to meet the energy mix target, which is achieved through some main point, which are determination of biomass composition to be used by comparing coconut monoculture with intercropping of several species of superior energy plants and internal external factors related to NRE development. The results of the calculation of the electricity projection with coconut monoculture scenario (0.0131 MWh/kg) while the energy crop intercropping scenario with jatropha (0.0182 MWh/kg); kemiri sunan (0.0178 MWh/kg) and nyamplung (0.0202 MWh/kg), it can be seen that coconut intercropping with nyamplung has the highest energy supply. In general, the land in Belimbing Village is suitable for planting coconut and nyamplung with an area of 1331.4 ha of the total land of Belimbing Village (2147 ha). Economically, the development of coconut and nyamplung EBT is feasible because they are able to produce NPV values reaching 54,480,863,468; Profitability Index 33.46; IRR 39,7%; and Payback Period 24 months. Then, the list of internal and external factors produces IFE (2.96) and EFE (2.59) values which indicate the potential for vegetable biomass in Belimbing Village is at the hold and maintain stage. The resulted are 14 alternative development strategies with 3 main strategies in order of priority, namely 1) prioritizing Belimbing Village in the electricity plan; 2) community empowerment through socialization, counseling and training; and 3) exploration of energy plants in accordance with the land potential of Belimbing Village, namely using a coconut intercropping system with nyamplung so that the target of Bali's energy mix can be achieved.
