Abstract

Background: Vocational education plays a crucial role in preparing competent graduates who meet industry needs. SMK MedikaCom Bandung, as a Center of Excellence school, continuously strives to enhance teacher competencies to improve the quality of graduates who can be absorbed into the workforce and to serve as a model for other vocational schools. The Department of Mechanical Engineering at SMK MedikaCom Bandung seeks to strengthen both teacher and student understanding of CAD/CAM technology through the application of CNC machines, supported by training and the integration of a (DfM)-based curriculum. Methods: The activities were conducted on August 22 and 27, 2025, through several stages, including socialization, FGDs, teacher training on DfM, development of digital teaching modules, and student mentoring in product-based projects. Evaluation was carried out using pre- and post-test instruments to measure differences in participants’ knowledge and skills before and after the program. Results: The test results indicated that all variables had p-values < 0.05, signifying a significant improvement. Teachers showed an increase in their understanding of CAD/CAM applications on CNC machines from 80% to 90% and in their knowledge of Project-Based Learning (PjBL) and Teaching Factory methods from 70% to 85%. Students also demonstrated improved comprehension of CNC utilization in non-conventional machining learning from 75% to 93%. Conclusions: The community service program effectively enhanced teachers’ and students’ mastery of CAD/CAM technology and their understanding of DfM. These outcomes support the implementation of an industry-based digital curriculum and strengthen the relevance of vocational school learning to workforce demands.

Abstract

Braiding machines are essential equipment in the textile industry for producing precise fibber or wire interlacements. Most conventional braiding machines in Indonesia are aging and lack adequate technical documentation. As a consequence, maintenance, component replacement, and component reproduction processes become difficult to perform. This study aims to recover technical data and develop the take-up mechanism of a conventional braiding machine through a reverse engineering approach. The research methodology consists of component identification through disassembly, dimensional measurement, 3D CAD modelling, component design modification, preparation of technical drawings, followed by assembly and functional testing. The results show that the modified component design has a simpler geometry, resulting in more efficient assembly and maintenance processes. Functional testing demonstrates that all components operate in accordance with the original mechanism, while performance testing indicates that the take-up system is capable of maintaining constant yarn tension and producing uniform braiding within a speed range of 100–160 RPM. Statistical analysis using an X̄ control chart confirms that the braiding quality remains within statistical control limits without significant deviations. Therefore, this study concludes that the reverse engineering method is effective in providing comprehensive technical documentation, extending machine service life, and supporting local manufacturing independence.Keywords - Dokumentasi Teknis, Mesin Braiding, Reverse Engineering, Sistem Penarik, X-Chart.
