Abstract

Indonesia is the world's third largest cocoa producer, leading to the high potential for cocoa processing and conversion to downstream industries. However, the downstream production of cocoa processing only reaches low utilization, around 40%. This problem also happens to UKM Ibunmanis in Bandung, which often fails to meet consumer demand. We have done a study to overcome this problem, aiming to make suggestions to improve production process technology,  to increase production capacity and ability to meet consumer demand. Here, we used Soft System Methodology (SSM) to provide solutions to the problems. The SSM consists of seven stages: Problem identification, Rich Picture Diagram, Root Cause Analysis coupled with CATWOE analysis, conceptual model activities (9 model activities), debating, improvement suggestions, and implementation. The results indicate that the transformation process carried out is in the form of processing chocolate bars into downstream products, with the limitation being conventional technology, which has model activities for designing appropriate technology for critical processing processes in UKM. Implementing the appropriate technology can speed up the production process from 30 minutes to 7 minutes or increase process efficiency by 77%. In addition, suggestions resulting from the method for the melting process can gain more profits and increase the sustainability of the SMEs

Abstract

The use of coal as the primary raw material for Steam Power Plants (PLTU) poses serious challenges related to sustainability, particularly due to high emissions, pollution risks, and supply chain dependence on non-renewable energy sources. Partial coal substitution with biomass is considered an effective strategy to reduce environmental impacts while supporting new and renewable energy targets. This study aims to analyze the potential of palm oil solid waste, wood pellets, and charcoal briquettes as coal substitutes using the Soft System Methodology (SSM) approach. The study follows seven SSM stages, starting from problem identification, compiling a problem description, formulating a root definition, CATWOE analysis, building a conceptual model, a debating process, and recommending corrective actions. The analysis results indicate that biomass substitution is feasible if supported by an integrated logistics system, the availability of biomass supplies, and compliance with the technical specifications for PLTU combustion. Biomass from palm oil waste, wood waste, and agricultural residues has a fairly stable energy value and can be obtained through a more environmentally friendly supply chain. Overall, this study confirms that the SSM approach is effective in understanding the complexity of coal-fired power plant problems and formulating renewable energy-based solutions through strengthening the biomass logistics system.Keywords - Biomass, PLTU, Renewable Energy, Soft Systems Methodology, Supply Chain Logistics.
