Abstract

PT Otomotif Indonesia is a Japanese manufacturing company. Company management continues to strive to improve the quality of products produced, including cylinder heads. Quality control is something that needs to be done in a company to minimise the occurrence of defective goods. The research was conducted in the machining section of the cylinder head manufacturing process. The highest cylinder head production percentage was 0.88% in November 2023. This research aims to minimise the occurrence of defects by applying the Seven Tools method. Seven Tools is a methodology consisting of seven quality control instruments: Check Sheet, Stratification, histogram diagram, Pareto diagram, scatter diagram, control chart, and Fishbone diagram. After data processing using the seven tools method, 5 errors were identified, the biggest being pen-matching errors. The 5W+1H method was used when analysing the Fishbone diagram and making recommendations for improvement. Keywords: Quality Control, Cylinder Head, Seven Tools

Abstract

General Background: Higher education learning systems require continuous improvement to ensure learning quality, student participation, and satisfactory academic outcomes. Specific Background: In an applied engineering course at a higher education institution in West Java, student attendance averaged 74.45 percent per meeting and was associated with incomplete learning experiences and repeat rates. Knowledge Gap: Prior studies predominantly evaluated learning methods or attendance outcomes without systematically designing learning innovations grounded in student needs and experiential data. Aims: This study aims to apply design thinking as a structured framework to identify attendance-related barriers and enablers and to formulate learning system innovations in an applied engineering course. Results: Findings indicate strong student preferences for offline lectures and simulation-based learning, while attendance is primarily enabled by interesting lecture materials and constrained by work obligations. Significant relationships were identified between age and selected learning formats, as well as between gender and specific assessment types. Incremental innovations such as flipped classrooms and guest lectures, alongside radical innovations including experiential learning and AI-based learning platforms, were formulated through the ideate phase. Novelty: This study frames student attendance and learning quality as a design challenge and empirically integrates attendance data, student preferences, and structured innovation using design thinking. Implications: The results provide a data-driven framework for lecturers and academic managers to redesign applied engineering learning systems through continuous improvement grounded in participation behavior and student-centered innovation. Highlights • Student attendance reflects learning system configuration.• Design thinking structures learning innovation based on empirical data.• Continuous improvement aligns learning design with student needs.
