Abstract

The garment manufacturing industry is required to maintain high production efficiency while meeting strict buyer specifications, particularly in make-to-order export-oriented operations. One recurring challenge in garment production is material allowance, which refers to excess material usage beyond planned requirements and may increase production costs while reducing resource efficiency. This study aims to analyze production business processes and identify factors contributing to material allowance in the manufacturing of Tommy Hilfiger products at PT XYZ, an export-oriented garment company in Indonesia. This research adopts a descriptive qualitative approach by applying the Activity-on-Arrow (AOA) method to map activity sequences and interdepartmental relationships across the production workflow. Primary data were collected through direct observation and semi-structured interviews, while secondary data were obtained from internal company documents and material usage records. Quantitative analysis of raw material consumption was conducted across three production seasons—Fall 2021, Pre-Spring 2022, and Spring 2022. A fishbone diagram was used to analyze the root causes of material allowance. The results show that material allowance consistently occurred at approximately 2% across all observed production seasons. AOA-based analysis identifies cutting and sewing processes as critical stages where rework and quality deviations frequently arise. Human-related factors and method-related issues were found to be the primary contributors to material allowance. These findings highlight the importance of improving process coordination, quality control, and operator management to reduce material allowance and enhance production efficiency.

Abstract

Campus canteens are essential facilities supporting academic activities. However, during peak hours, issues such as disorganized queues and delayed order deliveries frequently occur. These conditions lead to a decrease in customer satisfaction and service efficiency. This community service activity aims to develop a queue management strategy to improve service quality in campus canteens. The methods used include direct observation, socialization, and training for canteen staff, as well as the implementation of a simple order identification system. The socialization of the “numbered tags” queue system to the vendors has been carried out as part of the efforts to enhance service efficiency and organization. Preliminary evaluations indicate that this system has the potential to reduce customer waiting times and improve service efficiency. The finding suggests that a simple technology approach based on a numbered system can be an effective solution for addressing disorganized queues and improving the quality of canteen services in the future. This finding provides a foundation for canteen managers in other educational institutions to implement similar systems.
