Kalimantan is considered as a megadiverse island in the world because of its wide variety of species of plants. This potency must be managed to obtain optimum added values. In the Master Plan of Development and Acceleration of Indonesian Economic (MP3EI), Kalimantan was programmed to be the center of mining processing and national energy reservoir. Energy based on renewable resources must be continuallydeveloped. Tarap fruit (Artocarpus sp) is a typical fruit of Kalimantan, which the pulp part can be consumed and the seed can be processed for kind of flour, while it bark can be processed for briquette with addition of spent bleaching earth (by product of refinery process of palm oil production). The aims of this study was to obtain alternative energy, in form of briquette, based on Kalimantan local comodities through a zero waste production process. First of all, we optimized the formula of product, which consisted of two components: Tarap fruit waste and spent bleaching earth. Then the quality of each formula was examined. The optimum formula was obtained with its characteristics as follows: calorific value: >4700 kcal kg-1, combustion ashes : < 16.20 %, water content : 11 %, sulphur content : 0.0098 (< 1 %), and compressive strength value was 13.7 kgcm-2. Based on those results, the waste of Tarap fruit could be developed and used as a source of renewable briquette.
