Abstract

PT SWA is a steel fabrication service company operating in the construction sector, where productivity performance plays a critical role in meeting project schedules and cost targets. This study aims to measure weekly productivity levels in the steel fabrication process and to identify the dominant factors contributing to productivity fluctuations. The research employs the Objective Matrix (OMAX) method to quantify productivity performance using selected productivity ratios, which is then integrated with Root Cause Analysis (RCA) to identify the underlying causes of productivity decline. The results reveal significant weekly productivity dynamics during the ten-week observation period. Productivity increased during Weeks 1 and 2, with the highest improvement recorded in Week 2, achieving a productivity index of 190%. However, a continuous decline was observed from Weeks 3 to 10, with the lowest productivity index occurring in Week 8 at −78.33%. The analysis indicates that machine-related disruptions, substandard raw materials, and insufficient operator skills were the primary contributors to low-performing productivity ratios and overall productivity deterioration. The novelty of this study lies in integrating weekly OMAX-based productivity measurement with RCA to provide data-driven, actionable improvement insights within the context of steel fabrication services. The findings offer practical managerial implications, highlighting the importance of preventive maintenance planning, material quality control, and operator competency development to stabilize and improve productivity performance. Keywords: Productivity Measurement, Objective Matrix (OMAX), Root Cause Analysis, Steel Fabrication Services

Abstract

Green Supply Chain Management (GSCM) has received increasing attention as a strategy to minimize the environmental impact of the healthcare supply chain. Not only GSCM, but digitalization practices are also believed to improve efficiency and reduce operational costs. This study aims to examine the role of digitalization as a reinforcing factor in the effectiveness of GSCM practices for environmental sustainability. This research began with hypothesis preparation, which consisted of three hypotheses. Furthermore, data on the assessment of the relationship between digitalization, green supply chain, and environmental sustainability were collected through questionnaires to Health Clinics in Padang. Data processing was carried out using the Partial Least Squares-Structural Equation Modelling (PLS-SEM) method with SmartPLS 3.0. The processing stages consist of structural model design, measurement model design, path diagram design, model evaluation, hypothesis testing, and IPMA analysis. From the processing results, digitalization and a green supply chain both make significant contributions to environmental sustainability at the Padang Health Clinic. Furthermore, based on IPMA's analysis, the implementation of green supply chain aspects and digitalization in the field has reached 69%. Nonetheless, there is still room for improvement to achieve better environmental sustainability. Therefore, to achieve environmental sustainability, health clinics need to emphasize and implement green supply chain and digitalization indicators.  Keywords: Digitalization, Sustainability, Green Supply Chain, Healthcare, PLS-SEM

Abstract

Competition in the manufacturing industry requires companies to improve operational effectiveness, particularly in inventory management. PT XYZ, which initially operated in the metal fabrication services sector, has expanded into manufacturing; however, during this transition, inventory was still recorded manually, leading to data discrepancies and operational issues. Observations from a stocktaking process conducted in June 2025 indicated that inventory accuracy was only 76%, resulting in delivery delays, inventory accumulation, and potential financial losses. This study aims to design and implement an AppSheet-based inventory management system to address these problems. The system was developed using the SDLC method with RAD approach, emphasizing rapid development and user involvement. The developed system includes features for recording incoming goods, outgoing goods, production output, and real-time stock monitoring. System functionality was verified through black-box testing, while system acceptance was evaluated using User Acceptance Testing and a user satisfaction survey. The results indicate that all system functions operated as expected and met user requirements, achieving an average user satisfaction score of 4,25. Although the evaluation of long-term improvements in inventory accuracy remains limited, the system is considered reliable and suitable for daily operational use. It is expected to improve the consistency of inventory data. Keywords: Inventory Management System, AppSheet, RAD

Abstract

Fourth-Party Logistics (4PL) has emerged as a critical strategic model for managing complex supply chains in the digital era. This systematic literature review analyzed 38 peer-reviewed articles (2020-2025) from the Scopus database to examine technological advancements and strategic roles of 4PL in supply chain management. Three research questions guided the analysis: optimization technologies supporting 4PL operations, strategic mechanisms improving supply chain outcomes, and cost reduction strategies enabling 4PL adoption. Findings demonstrate that advanced optimization technologies including Conditional Value-at-Risk (CVaR), stochastic programming, and reinforcement learning effectively manage transportation uncertainty and enhance operational efficiency. Strategic mechanisms such as coordinated ICT infrastructure, sophisticated matching models, and innovative financing arrangements significantly improve service quality and customer satisfaction. Cost reduction and sustainability strategies, including flexible resource management, warehouse optimization, and blockchain implementation, enable organizations to achieve cost reductions up to 38% while maintaining environmental compliance. However, implementation barriers in regulatory compliance, human resource management, and digital infrastructure remain significant challenges. The research concludes that 4PL adoption requires integrated approaches balancing technological innovation with organizational capability development. Future research should prioritize context-specific implementation frameworks for emerging markets, particularly in developing economies such as Indonesia, to address unique supply chain challenges while supporting economic growth and operational resilience. Keywords: Customer Satisfaction, Fourth-Party Logistics, Outsourcing Strategy, Supply Chain Management
