Abstract

NT is a Japanese automotive components company that produces automotive products tappet. The quality problem found was the high level ofdefect which was produced in August to October 2024, there were a total of unitsdefect what happened was 4826 units, of the total the type defect dakon chomen became the most dominant, recorded at 2743 units or 57% of the total defect. Therefore, this research is focused on the analysis of the types of defects in dakon chomen. The research method uses the PDCA cycle supported by seven tools (Pareto diagram and fishbone) and 5W1H analysis. Stages plan determine the problem, defect what will be fixed and the causal factors defect, stages do determine the proposed improvements that must be made, the stage check carry out monitoring after carrying out repairs and stages action standardization to maintain product quality. Based on the results of the implementation of the PDCA method, it shows that the number of types defect dakon chomen successfully reduced significantly from 2743 to 1244 units in the period November 2024 to January 2025. This reduction is equivalent to an improvement effectiveness of 55.3%. Keywords: Defect, PDCA, Quality Control, Tappet

Abstract

A risk of musculoskeletal disorders (MSDs) due to non-ergonomic work postures was found in herbal medicine sellers. This study aims to analyze the posture and ergonomic risk levels using RULA, REBA, and Nordic Body Map (NBM) through observation and interviews with three respondents (aged 21, 33, and 63 years) who work an average of 2–3 hours per day with a load of 7 kg. The results of the study using Rula and Reba showed that the work posture was not fully ergonomic, with Rula values ​​of 4 and  Reba  values of 9. RULA and REBA values ​​indicate a moderate to high risk level, especially in elderly respondents. Although there have been no significant musculoskeletal complaints, the potential for musculoskeletal disorders can increase if work habits are not immediately corrected. It is necessary to apply ergonomic principles such as using a more ergonomic carrier (wide and soft straps), adjusting the load balance, taking active breaks and stretching, using alternative pushing aids (trolleys) on flat areas. Overall, the workload is still considered safe according to metabolic energy, but body efficiency decreases with age. Keywords: Ergonomics, Herbal Drink Seller, NBM, RULA, REBA

Abstract

Sustainable organic waste management is a crucial issue considering the serious negative impact of landfilling. Although organic waste has great potential to be processed into compost or eco-enzymes, small-scale conventional shredders often face obstacles such as low efficiency, monolithic structures, and reliance on the power grid, which hinder adoption at the communal level. This research aims to optimize the productivity of organic waste shredding machines with a capacity of 20 kg/hour through design modifications. The methodology applied is experiment-based Research and Development (R&D). The modifications made include the implementation of a modular design (dismantling) to overcome logistical constraints and the conversion of the drive system from an electric motor to a 6.5 HP gasoline motor to ensure independent operations at the site. Comparative performance evaluation was measured using the Marvin E. Mundel Productivity Model. The test results show a significant improvement in performance. The modified machine achieved a Productivity Index (IP) of 1,579, reflecting an increase in production effectiveness of 57.9%. This increase is also supported by processing time efficiency of 36.7%, reducing the enumeration time of 5 kg of waste to 19 minutes. In conclusion, design modification strategies that focus on adapting energy sources and improving mobility are very effective in producing appropriate technologies that are efficient and ready to be implemented in society.

Abstract

This study explores the service quality of J-Cello Vermak, a small and medium-sized enterprise (SME) in the garment repair sector, and assesses customer satisfaction using the SERVQUAL method. Established in 2021, the SME faced difficulties in collecting objective data on satisfaction, particularly regarding timeliness, stitching quality, and Responsiveness. A quantitative descriptive method using questionnaires and interviews was used, analyzed using validity and Reliability tests and gap analysis across five SERVQUAL dimensions: Tangibles, Reliability, Responsiveness, Assurance, and Empathy. The results indicate generally positive customer satisfaction, with positive gaps across all dimensions. Assurance and Empathy had the highest gaps, reflecting employee trust and Empathy. However, Responsiveness needs improvement due to its lowest gap, indicating a need for faster service. Correlation and regression indicate a weak positive relationship between service quality and satisfaction. Recommendations focus on improving speed, Responsiveness, and ongoing quality management for customer loyalty and competitiveness. These findings are important for the business strategy of SMEs in the garment alteration  service sector.

Abstract

Improving customer complaint handling is crucial for the sustainability and success of a business, as efficient and responsive complaint handling demonstrates a company's commitment to meeting customer needs and expectations, thereby enhancing customer satisfaction. The automotive industry sets a 14-day working day standard for complaint resolution. However, the actual complaint handling process often takes an average of 26 days. By implementing a traceability system, integrating a Value Stream Mapping (VSM) approach, and adopting Industry 4.0 transformations, this research aims to reduce the handling time. Moreover, by mapping the workflow through Visual Stream Mapping, inefficiencies can be identified, and through the implementation of a Traceability System and the development of system-based processes, the transformation achieved through the conceptual model of Industry 4.0 adoption can improve the process from 26 working days to 7 working days. Keywords: Customer Complaint, Traceability, VSM
