Abstract

The appearance of four-wheeled vehicles is the first aspect observed by customers. Defects in appearance, such as gaps in the rear combination lamps, can reduce the competitiveness of Multi-Purpose Vehicle (MPV) products. Such defects affect product quality and customer satisfaction, making it essential for companies to minimize defects to enhance market competitiveness. This study applies the QCC (Quality Control Circle) method with a PDCA (Plan-Do-Check-Action) approach, supported by the 8-step problem-solving process and 7 QC tools. The method aims to identify the root causes of defects and implement appropriate corrective actions. In its implementation, the Plan phase involves identifying the problem and analyzing root causes using QC tools such as Pareto charts and fishbone diagrams. In the Do phase, corrective actions are carried out by adjusting processes or materials. The Check phase includes evaluating the results of the corrective actions, while the Action phase ensures the changes are sustained over time. Using the QCC method, defect rates per unit decreased from 0.130 to 0.004.

Abstract

Vocational High Schools (SMK) have an important role in preparing graduates who are ready to work and able to meet industry needs. However, there is still a competency gap between students' abilities and the demands of the world of work, especially in terms of product quality inspection. This Community Service Activity (PKM) aims to improve SMK students' understanding and skills regarding product quality concepts, quality standards, and manufacturing product inspection techniques through training and practice-based learning. Activities were carried out at one of the SMKs in the Cikarang area and were attended by 20 students. Training included lectures on basic product quality concepts, demonstrations on the use of measuring tools such as rulers and calipers, product inspection practices, as well as discussions and evaluations of inspection results. Results showed a significant improvement in students' understanding of quality concepts and product inspection procedures, with an average post-test score increase of 58%. A total of 85% of participants were able to perform simple product inspections in accordance with standard operating procedures (SOP). In addition, this training also contributed to the strengthening of soft skills such as accuracy, discipline, responsibility, cooperation, and critical thinking skills. This program of community service has proven effective in reducing the skill gap between education and industry needs, as well as improving the readiness of vocational school students to face the challenges of modern manufacturing.
