Cacao processing industry produces cocoa butter, cocoa powder, and generates by-product in the forms of pod husk and bean shells which can be utilized as an energy source. The objectives of this research was to develop an energy independent model of a closed system production process for cocoa butter and cocoa powder. This closed system model was developed by analyzing mass balance, assessing the potential energy of by-products, and building a closed system cacao processing industry. To improve it comprehensiveness, this study reviewed secondary data from relevant literatures. Results from this study showed that the achievable yield of cocoa butter and cocoa powder was 32% and 50%. Respectively cacao industry with a capacity of 4,500 kg of cacao per day has the potential energy of 14,561,293.2 kCal per day derived from the pod husk and bean shells. This potential energy is able to meet the energy requirements for the production process. This study explained that the cacao industry is potentially be an energy independent industry by optimize the utilization of by-products.
