Abstract

 PT TBA as a manufacturing company in the automotive industry faces quality problems in the form of defects in the wrong assembly arm in the Inner Left Normal process of Seat Frame Front Cushion products in the EFC Line Adjuster. Based on data for the March-May 2025 period, the average defect reaches 1.3 pcs per month and has the most dominant cost impact compared to other types of defects, with a potential material loss of up to IDR 6,236,708 per year. This study aims to identify the root cause of the problem and reduce the number of defects to zero defects through the application of the Quality Control Circle (QCC) method with an eight-step approach based on the PDCA cycle. The results of the analysis showed that the main cause came from the incompatibility of the arm rack design which allowed the mixing of right and left components, uncontrolled part picking methods, and the lack of optimal error prevention system (poka-yoke) on the machine. Improvement actions are carried out through modification of the rack design following the shape of the arm, the installation of a lever and gravity-based mechanical cover system, and the integration of sensors and poka-yoke systems in the process area. After all stages of QCC were implemented, defects were successfully reduced to 0 pcs per month consistently from August to October 2025 or a decrease of 100%. The impact of the improvement not only improves the quality aspect, but also eliminates the potential cost loss to Rp 0, without affecting the aspects of safety, delivery, and employee morale. These results prove that QCC is effective as a sustainable quality control approach in the automotive industry.

Abstract

Fire is one of the main risks in industrial environments that can cause significant losses. PT XYZ has 185 fire protection devices, with fire extinguishers (APAR) and hydrants as the primary components totaling 62 units. Observations revealed that 17 of 51 APAR units (33%) and 3 of 11 hydrant units (27%) were in substandard condition, caused by a manual inspection system with weaknesses including paper-based data vulnerable to loss, lack of centralized monitoring, difficulty tracing inspection history, no expiry reminders, and slow data compilation. This study aims to analyze the actual condition of fire protection equipment, evaluate inspection compliance, and implement a QR Code-based digital inspection system using the Plan Do Check Act (PDCA) method. Simulation on 15 APAR units and 5 hydrant units demonstrated a 35% time efficiency improvement, reducing inspection time from 71 to 46 minutes. The digital system outperformed the manual system across all evaluation indicators. The estimated full implementation cost for 62 units is IDR 2,248,000, considered proportional to the risks of fire protection system failure

Abstract

The growing demand for customized products and shorter delivery times has intensified the pressure on logistics and warehouse operations to become more efficient, flexible, and responsive. In this context, selecting an appropriate automated storage and retrieval system (AS/RS) is a complex multi-criteria decision-making (MCDM) problem that requires a systematic, quantitative evaluation approach. This study proposes an integrated decision-making framework that combines the Analytic Hierarchy Process (AHP) and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to determine the most suitable automated storage technology for warehousing operations. Four key criteria were identified—Throughput, Accuracy, Ergonomics, and Space Utilization—and three alternatives were evaluated: Miniload, Vertical Carousel, and Vertical Lift. The AHP method was used to derive the relative importance of the criteria, producing consistent weights with a CR value of 8.28%. These weights were subsequently applied in the TOPSIS analysis to rank the alternatives based on their closeness to the ideal solution. The results indicate that Vertical Lift emerged as the optimal choice (CC = 0.6657), followed by Vertical Carousel (CC = 0.4657) and Miniload (CC = 0.3688). Sensitivity analysis, conducted through both One-at-a-Time (OAT) and scenario-based approaches, confirmed the robustness of the decision model under varying preference scenarios. This research contributes to the body of knowledge on warehouse automation decision-making by providing a transparent, quantitative, and adaptable framework that supports managers in enhancing operational performance and optimizing resource utilization.

Abstract

The objective of this community service activity was to determine the extent to which employees understand the company’s system for implementing the 5S concept, to identify problems in the application of 5S during work processes, and to establish appropriate control measures and follow-up actions for 5S implementation at PT Fanah Jaya Maindo. The method used in this activity was the 5S method, which is a technique for maintaining the quality of the work environment by enhancing orderliness, creating a safe and comfortable workplace, and improving efficiency and productivity. Participants in this activity consisted of all staff and supervisory employees working at PT FJM. Based on observation results, the problem identified in the implementation of 5S was the suboptimal application of the Seiketsu (standardization) principle. This issue indicates the need for a more structured system of tool coding and an obligation for each employee to return work equipment to its original place after use. The results of the socialization activity showed that participants gained a very good understanding of the material presented. Positive participant responses were reflected in the appreciation expressed toward both the content and the manner in which the activities were delivered. This achievement of understanding is expected to encourage an increased commitment among employees to apply the 5S principles consistently in their respective work environments

Abstract

The assembly process of automation machine enclosures based on aluminum profiles at PT XYZ is still performed manually at low working positions, causing workers to frequently adopt bent, squatting, and prolonged sitting postures. These conditions may increase the risk of Musculoskeletal Disorders (MSDs), which can reduce worker comfort and productivity. This study aims to analyze the level of working posture risk in the enclosure assembly area, identify the body parts experiencing the highest level of discomfort, and design a work aid to reduce ergonomic risks. The research employed the Nordic Body Map (NBM) method to identify musculoskeletal complaints and the Rapid Entire Body Assessment (REBA) method assisted by Ergofellow software to evaluate working posture risks. The results indicated that the dominant complaints were experienced in the back, lower back, neck, shoulders, and hands. The REBA assessment produced a score of 7 for the first worker, categorized as a medium risk level, and a score of 8 for the second worker, categorized as a high risk level. Based on these findings, an ergonomic work chair was designed with adjustable height, back support, and wheels to improve work flexibility. The implementation of the proposed work aid is expected to reduce the risk of MSDs, enhance worker comfort, and improve productivity in the enclosure assembly process
