Abstract

General Background The increasing consumption of fast food has driven the need for efficient food production technologies, particularly in burger manufacturing. Specific Background Burger buns require uniform application of sesame seeds and liquid coating to maintain product quality and consistency. Knowledge Gap Conventional manual methods and existing machines still face limitations in efficiency, uniformity, and material usage optimization. Aims This study aims to design and analyze a sesame sprinkling and spray machine using two different conceptual models to improve production performance. Results The design process utilized SolidWorks simulation, showing that concept A produced a maximum von Mises stress of 38.10, while concept B reached 38.71. The safety factors were 4.46 and 4.39, respectively, indicating both designs are structurally safe. Concept B demonstrated better performance in terms of cost efficiency and more uniform sesame distribution due to its oscillating sieve mechanism. Novelty The study introduces a comparative design approach combining spraying and sprinkling mechanisms with improved uniformity through an eccentric motion system. Implications The findings provide practical insights for developing more efficient and cost-effective machinery in small to medium-scale burger production industries. Keywords: Burger Buns, Machine Design, Sesame Sprinkling, Spray System, SolidWorks Simulation Key Findings Highlights Concept B shows superior cost efficiency and distribution uniformity Both models meet safety standards based on structural simulation Oscillating sieve mechanism improves sesame application consistency me Spraying Machine for Burger Bun Production

Abstract

General Background: Quality control is essential in manufacturing industries to ensure product consistency and minimize defects. Specific Background: A sugar production company experienced significant product defects during the May–October production period, particularly in forms such as krikilan, refined sugar, and molasses. Knowledge Gap: Previous studies often apply quality control tools separately, with limited integration between statistical tools and root cause identification methods. Aims: This study aims to identify defect types, analyze root causes, and propose improvement strategies in sugar production processes. Results: The findings show that the highest defects occurred in krikilan with 1671 kwintal, followed by refined sugar and molasses. Analysis using seven tools revealed dominant defect patterns, while Root Cause Analysis identified five main contributing factors: machine, material, method, man, and environment. Novelty: The study integrates seven tools with RCA using the 5 Whys approach to provide a more structured and comprehensive defect analysis. Implications: The results suggest practical improvements including machine maintenance scheduling, stricter raw material inspection, and employee training to reduce defect rates and improve production efficiency. Keywords: Quality Control, Seven Tools, Root Cause Analysis, Sugar Production, Defect Analysis Key Findings Highlights Krikilan defect dominates total production issues across observed periods Integrated analysis reveals five primary sources of production failure Structured improvement actions focus on maintenance, supervision, and workforce capability

Abstract

This study examines quality control issues in a carton printing company experiencing defect rates exceeding the established standard. General Background: Quality control plays a critical role in maintaining product consistency and competitiveness in manufacturing industries. Specific Background: The observed defect rates in the company surpassed the acceptable threshold, reaching up to 1.6% in recent months. Knowledge Gap: Previous approaches have not fully integrated structured statistical analysis with strategic planning tools to address recurring defects. Aims: This research aims to identify defect types, analyze root causes, and propose improvement strategies using Six Sigma with the DMAIC approach combined with SWOT analysis. Results: The findings indicate an average DPMO value of 3874.569 and a sigma level of 4.16, revealing that the process performance is still below the Six Sigma target. Root causes were identified across five factors: human, machine, method, material, and measurement. Novelty: The integration of Six Sigma and SWOT provides a structured analytical and strategic framework for quality improvement. Implications: The proposed strategies, including SOP standardization, operator training, real-time monitoring, and quality audits, are expected to reduce defects and support sustainable operational performance. Keywords: Quality Control, Six Sigma, SWOT Analysis, Carton Production, Defect Reduction Key Findings Highlights Process capability remains below optimal standards based on sigma level evaluation Root causes consistently originate from five main production factors Strategic integration supports structured quality improvement actions
