Abstract

General Background Quality control is essential in manufacturing systems to maintain product consistency and minimize defects. Specific Background Production processes often experience defects that reduce quality performance and increase operational inefficiencies. Knowledge Gap Previous studies have applied quality control methods separately, with limited integration of Six Sigma and Failure Mode and Effects Analysis (FMEA) for comprehensive defect evaluation. Aims This study aims to identify dominant defects, analyze root causes, and determine priority corrective actions in a manufacturing process. Results The findings reveal that several defect types dominate production, with sigma level indicating the need for improvement. Root causes are identified through systematic analysis, while FMEA determines priority risks based on Risk Priority Number values. Novelty This study integrates multiple quality control tools in a structured framework for defect evaluation. Implications The results provide guidance for improving production processes and reducing defect rates in manufacturing systems. Keywords: Quality Control, Product Defects, Six Sigma, FMEA, Manufacturing Key Findings Highlights Dominant defect types identified in production process Risk ranking highlights critical failure priorities Integrated analysis supports structured decision making

Abstract

General Background Shrimp cracker production requires strict quality control, particularly in moisture content, which determines texture, shelf life, and defect occurrence. Specific Background In industrial practice, defects such as mold growth remain a critical issue due to suboptimal drying and process control conditions. Knowledge Gap Previous studies have not fully integrated process optimization and root cause identification to address both quality parameters and defect sources simultaneously. Aims This study aims to optimize drying parameters and identify root causes of defects using Response Surface Methodology (RSM) and Root Cause Analysis (RCA). Results The optimal conditions were obtained at a temperature of 70°C, drying time of 60 minutes, and thickness of 5 mm, producing a moisture content of 9.00% with a desirability value of 1.00. RCA findings indicate that mold defects are caused by high raw material moisture, inadequate storage conditions, and limited production supervision. Novelty This study integrates RSM-based parameter optimization with RCA-based defect analysis within a single framework. Implications The results provide practical recommendations for improving production control, reducing defects, and maintaining consistent product quality in shrimp cracker manufacturing. Keywords: Shrimp Cracker, Process Optimization, Moisture Content, Response Surface Methodology, Root Cause Analysis Key Findings Highlights Optimal drying parameters identified through statistical modeling approach Major defect source linked to raw material and process control conditions Integrated analytical framework supports systematic quality improvement

Abstract

Produksi kaos sablon merupakan bagian dari industri kreatif yang berkembang pesat di Indonesia, tetapi masih menghadapi berbagai kendala seperti pemborosan waktu, penggunaan bahan yang tidak efisien, dan ketidakkonsistenan hasil produksi. Penelitian ini bertujuan untuk meningkatkan produktivitas produksi kaos sablon melalui penerapan Lean Manufacturing menggunakan Current Value Stream Mapping (CVSM), Value Stream Analysis Tools (VALSAT) menunjukkan pemborosan terbesar terjadi pada kategori processing (25%) dan waiting (20%), yang disebabkan oleh SOP yang belum distandarisasi, waktu setup screen panjang, mesin lama, dan kualitas bahan baku yang tidak konsisten. Implementasi perbaikan menghasilkan penurunan cycle time dari 22.007 detik menjadi 14.892 detik, pengurangan potensi cacat, dan penurunan waktu tunggu antar proses. Sementara itu, pendekatan Kaizen mampu mengoptimalkan aliran produksi, mengurangi pemborosan, meningkatkan kualitas, serta mempercepat penyelesaian pesanan, sehingga dapat meningkatkan daya saing UMKM di industri kreatif.
