Abstract

This research focused on improving production efficiency in the Lean Manufacturing Laboratory at Universitas Mercu Buana by addressing bottlenecks at the Vacuum and Trimming stations. Utilizing the PDCA methodology, the study aimed to reduce processing times and enhance accuracy through tool design and motion study. The Operational Process Chart identified inefficiencies, while Seven Waste Analysis highlighted key areas for improvement. The application of TRIZ principles led to the development of a flexible cutting press, designed to integrate vacuuming and cutting processes. Measurements using right-hand and left-hand chart facilitated the creation of a new operating procedure. The implementation of the flexible cutting press resulted in a 21.34% reduction in cycle time, demonstrating effective optimization of work layout and tool design. Despite its success, the study has limitations including the lack of a comprehensive cost-benefit analysis and limited product variety. Future research should explore long-term economic impacts and applicability to diverse production contexts.

Abstract

This study aims to enhance efficiency in the Lean Manufacturing practicum at the Lean Manufacturing Laboratory of Universitas Mercu Buana by applying PDCA (Plan-Do-Check-Act) and TRIZ (Theory of Inventive Problem Solving) methods. The primary focus was the design and implementation of a flexible jig tool to reduce processing time and increase precision in the vacuum, trimming, and assembly stages designing and implementing. Results showed that the flexible jig reduced process time by 37.8%, from 1431 seconds to 890 seconds, and improved the level of automation from fully manual to the use of flexible tools. Further evaluation revealed significant gains in productivity. The study utilized tools such as Value Stream Mapping (VSM), Operation Process Chart (OPC), and the seven waste concepts within the PDCA framework to identify key issues in the manufacturing process. The application of TRIZ principles in tool design also significantly enhanced production efficiency. This research presents compelling evidence that systematic approach like PDCA and creative methodologies for instance TRIZ can substantially improve operational performance in light manufacturing practicums. Additionally, it highlights the important role of higher education in fostering technological innovation and industry collaboration to tackle evolving manufacturing challenges.
