Abstract

PT XYZ faces challenges in declining product quality due to production defects exceeding the optimaltolerance limit of 2% per period for six consecutive periods. This research aims to identify and addressdefects, offering action strategy recommendations to mitigate and prevent their recurrence during theproduction of grey fabric on RRC shuttle loom machines. The study utilizes an integrated analysis method,combining Fault Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA). The researchhighlights five major defect types in grey fabric products, constituting 80% cumulatively. These defectsinclude pickbar issues, ambrol (fraying), tears, broken threads, and skipped weaving. Twelve root causescontributing to these defects in RRC shuttle loom production are identified and evaluated based on theirRisk Priority Number (RPN), categorized into classes A, B, and C with varying risk intensities. Two rootcauses from Class A, constituting 20% cumulatively, are identified as primary defect causes. These issuesinvolve the fit of the weaving reed and discrepancies in the let-off and take-up motion mechanism on theloom machine, each with an RPN value of 648. Action strategy recommendations are provided for thesetwo root causes, collectively contributing to 20% of the overall problem percentage. The objective is toprevent the recurrence of the five major defect types, accounting for 80% of the cumulative percentage.This comprehensive approach aims to rectify the identified issues, ensuring a higher standard of productquality in the textile manufacturing process

Abstract

Waste management poses a critical global challenge, particularly in developing countries. Refuse-Derived Fuel (RDF) offers a promising solution, necessitating holistic sustainability evaluations through Life Cycle Sustainability Assessment (LCSA). Aim: This study aimed to conduct a systematic and bibliometric review mapping trends, analyzing methodologies, identifying barriers, and evaluating strategies concerning LCSA development in RDF life cycles within developing countries. Methodology and results: Employing a Bibliometric-Systematic Literature Review (B-SLR) using Scopus data (2011-2024) and analyzed via VOSviewer and qualitative content analysis, the study identified 22 relevant publications. Findings reveal a fluctuating yet growing publication trend with increasing citations, though international collaboration remains limited despite concentrated productivity. Methodologically, studies predominantly use LCA and LCC, with scarce S-LCA integration; key themes include environmental impacts, waste-to-energy (especially RDF in cement), and circular economy. Implementation faces significant technical, economic, social, and regulatory barriers. Proposed strategies emphasize crucial advancements in infrastructure, process optimization, stakeholder engagement, and robust regulatory frameworks. Conclusion, significance and impact study: The findings confirm that while scholarly interest in LCSA for RDF is increasing, its application is fragmented and hindered by persistent barriers. This research provides a crucial synthesis of evidence-based insights for policymakers and enriches academic understanding of LCSA in alternative waste management. Future work should prioritize developing integrated LCSA methodologies (especially for S-LCA), addressing critical data gaps, conducting holistic case studies, fostering international collaboration, and validating proposed strategies to accelerate sustainable RDF adoption and comprehensive waste management.

Abstract

Sunflowers are commodities with the potential to be developed into derivative products such as cooking oil, herbal oil, animal feed, and even biodiesel. However, stakeholders in the sunflower agro-industry, from farmers to producers of derivative products, still face several challenges in creating the best practices for sunflower agro-industry. These challenges include the underutilization of technology and the application of supply chain management. Therefore, this research focuses on designing a prototype decision support system for value added products in the sunflower agro-industry supply chain network. The purpose of this research is to support stakeholders in making informed decisions regarding the production of sunflower derivative products, including cooking oil, herbal oil, and animal feed. The development of this decision support system design utilizes the system development life cycle (SDLC) method with a waterfall model. The prototype design results employ the Just in Mind application for creating a graphical user interface and will be implemented on smartphones using the Android system. This research is limited to supporting decision-making in the value-added model of the sunflower agro-industry supply chain. The implementation of the system is considered a subsequent stage in future research. Additionally, the addition of other models is expected to be developed in future studies.

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.
