Abstract

Perkembangan teknologi industri modern menuntut penguasaan sistem desain dan manufaktur berbasis komputer, khususnya Computer-Aided Design (CAD) dan Computer-Aided Manufacturing (CAM), yang berperan penting dalam mewujudkan proses perancangan dan produksi digital yang efisien, presisi, dan adaptif terhadap era Industri 4.0. Namun, pemahaman CAD/CAM di tingkat sekolah menengah masih terbatas akibat keterbatasan fasilitas dan akses pembelajaran berbasis teknologi industri. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan literasi teknologi serta memperkenalkan konsep dasar CAD/CAM kepada siswa SMA Muhammadiyah 1 Purwokerto. Kegiatan ini dirancang untuk memperluas wawasan dan minat siswa terhadap alur desain digital hingga manufaktur serta relevansinya dengan dunia kerja dan pendidikan tinggi. Materi disampaikan melalui studi kasus sederhana, diskusi interaktif, dan demonstrasi langsung pembuatan gambar CAD/CAM pada perancangan produk fungsional, seperti mesin pemotong kentang. Pendekatan pembelajaran berbasis praktik diharapkan mampu menumbuhkan pola pikir rekayasa (engineering mindset) dan memperkuat pemahaman siswa mengenai peran CAD/CAM dalam menghasilkan solusi inovatif di industri modern. Melalui kegiatan ini, Program Studi Teknik Industri Telkom University Purwokerto berkontribusi dalam pengembangan literasi teknologi siswa sekolah menengah sekaligus memperkuat citra program studi melalui pengenalan rekayasa industri yang inspiratif dan aplikatif.

Abstract

Defective products are a significant issue in the production process because they lead to increased working time and operational costs. This study aims to analyze the main causes of defects in 1 m³ oxygen trolley products at CV XYZ and to formulate improvement proposals to reduce the product defect rate. The Six Sigma method with the DMAIC (Define, Measure, Analyze, Improve, Control) approach was systematically applied. In the Analyze stage, the main factors causing defects included the use of paint materials that did not meet standards, lack of worker accuracy, suboptimal working environment conditions, inconsistencies in the production process, and problems related to machines and equipment. The proposed improvements included the use of standardized epoxy powder coating paint, the implementation of a 5R culture to improve workplace organization and efficiency, and the application of a check-and-balance system at every stage of the painting process. The implementation of these improvements resulted in a reduction of the dominant defect percentage from 61 percent to 40 percent. In the Control stage, analysis using a P-Chart showed that the defect proportion remained within control limits and tended to decrease. The increase in the Sigma value from 2.30 to 2.36 indicates a significant improvement in product quality.

Abstract

PT XYZ faces a high downtime problem in Cement Mill Unit One, which has an impact on decreasing productivity and operational efficiency. This study aims to evaluate the effectiveness level of the machine using the Overall Equipment Effectiveness (OEE) method and to identify the root causes of the problems through Six Big Losses analysis and Fishbone Diagram. The results show that the average OEE value of Cement Mill Unit One in 2024 only reached 57 percent, which is still below the international ideal standard of 85 percent. This low effectiveness is dominated by idling and minor stoppages at 32.30 percent, followed by reduced speed losses at 23 percent, and equipment failure loss at 17.57 percent. Through the Fishbone Diagram analysis, the main causes of these losses were found to originate from human, machine, method, and environmental aspects. The proposed improvement recommendations include digitalizing maintenance documentation, implementing strict routine maintenance scheduling, improving operator competence, controlling the moisture content of input materials, and optimizing workplace cleanliness.
