Abstract

This study addresses inefficiencies in the warehouse layout of a paper production company in Pasuruan, East Java, which led to delayed deliveries. By implementing shared storage (SS) using FIFO and class-based storage (CBS), the research aimed to optimize space and improve material handling efficiency. Data collection involved observation, interviews, and company records. The proposed layout reduced space usage from 59.45% to 16.95% and achieved significant time savings: 17.84% for brown paper, 8.84% for white paper, and 28.51% for custom-colored paper. The findings suggest that a systematic layout can greatly enhance warehouse efficiency. Future studies should consider the cost factors associated with these improvements. Highlights: Space Efficiency: Reduced usage from 59.45% to 16.95%. Time Savings: Up to 28.51% for custom-colored paper. Data-Driven: Used observations, interviews, and records for layout optimization Keywords: Warehouse layout, material handling, shared storage, class-based storage, efficiency improvement

Abstract

PT. XYZ, a manufacturer of car exhaust components, faces significant defect-related challenges, impacting productivity and market competitiveness, particularly in Europe. Over six months, 3.18% of 184,708 produced components were defective. This study aims to determine the sigma level of quality control and identify root causes of defects using the Six Sigma DMAIC method and Root Cause Analysis (RCA). Observations and interviews revealed human error, machine issues, improper methods, substandard materials, and environmental factors as key contributors to defects. The sigma level was found to be 4, indicating suboptimal quality control. Recommendations for improvement include SOP development, operator training, standardized production methods, regular machine maintenance, and 5S organizational practices. Implementing these could reduce defects and improve productivity. Highlight: Defect Rate: 3.18% in 184,708 components. Sigma Level: Evaluated at level 4. Improvements: Implement SOPs, training, maintenance, 5S practices. Keyword: Quality Control, Six Sigma, Root Cause Analysis, Manufacturing, Car Exhaust Components

Abstract

PT P, a sugar manufacturing company, has a sugar factory located in the Sidoarjo area. SHS sugar and quality manufacturing company. Production problems often cause long production delays, therefore managing the production process is very important. Failure modes and effects analysis (FMEA) was used to determine possible failure modes of sugar production. In the test results, various kinds of problems were found: transportation, grinding, purification, evaporation, crystallization. There are 5 factors that cause production inefficiency, namely: human factors, word methods, environment, raw materials and machines used. This resulted in that when the sugar production process was not optimal at PT P, the FMEA method was used to minimize production constraints in order to achieve production targets. After observing using the FMEA method, a value of 480 was obtained in the milling process.

Abstract

General Background: Warehouse layout plays a critical role in supporting material handling efficiency and operational performance in industrial systems. Specific Background: The studied company experienced excessive travel distance and disorganized item placement, leading to inefficiencies in retrieval and storage activities. Knowledge Gap: The existing warehouse arrangement had not applied a systematic storage classification based on item movement frequency, resulting in suboptimal space utilization and material flow. Aims: This study aims to redesign the warehouse layout using the Class Based Storage method to minimize travel distance and improve storage organization. Results: The analysis classified items into movement-based categories and proposed a new layout configuration that reduced total travel distance compared to the initial condition. The redesigned layout also improved accessibility for high-frequency items. Novelty: The study demonstrates the practical application of Class Based Storage in a specific industrial warehouse context supported by quantitative travel distance analysis. Implications: The findings provide a structured reference for warehouse management strategies focused on layout planning, storage classification, and operational efficiency improvement within industrial engineering practices. Keywords: Warehouse Layout, Class Based Storage, Travel Distance, Material Handling, Industrial Engineering Key Findings Highlights Storage classification based on movement frequency reorganized item placement systematically. Proposed configuration lowered total material transfer path compared to the initial arrangement. High-rotation products were positioned closer to access points to streamline retrieval activities.

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
