Abstract

The increasing complexity of manufacturing systems requires companies to continuously improve production efficiency through effective facility layout design. CV. XYZ, a manufacturer of 10-ton wooden drums, experiences inefficiencies caused by long material handling distances, backtracking movements, and high operational costs resulting from its existing production layout. This study aims to optimize the facility layout using the Systematic Layout Planning (SLP) method integrated with BLOCPLAN software to identify the most efficient layout alternative. Primary data were collected through direct observation, time studies, interviews with production personnel, and documentation of workstation dimensions and production flow. The proposed layouts were evaluated using Activity Relationship Chart (ARC), Activity Relationship Diagram (ARD), material handling distance, travel time, and material handling cost (OMH). The results indicate that the SLP-based layout reduced material travel distance by 38%, travel time by 38%, and material handling cost by 25%, while the BLOCPLAN layout achieved reductions of 35%, 35%, and 20%, respectively. Compared with the algorithm-generated layout, the manually developed SLP layout provided superior operational efficiency while maintaining existing production constraints. The novelty of this research lies in the quantitative comparison between manual SLP and algorithm-based BLOCPLAN layouts for a complex wooden drum manufacturing process involving 31 production stages. The findings provide practical guidance for improving facility layout efficiency in wood-based manufacturing industries.

Abstract

This research aims to identify main causes of product defects in electroplating process at PT. X, an automotive component manufacturing company, and formulate improvement proposals to enhance product quality. Approach used is Six Sigma-DMAIC (Define, Measure, Analyze, Improve, Control) combined with Failure Mode and Effect Analysis (FMEA) method. Initial research was conducted by identifying types of product defects. Measurement results showed a Defects Per Million Opportunities (DPMO) value of 18909 with a sigma value of 3,59, indicating that quality was within industry average levels and required improvement. Pareto analysis revealed that a dominant defect was dirtiness, contributing 37,7%. Through cause-and-effect analysis and FMEA, main factors causing dirtiness were operators not installing dummy plates, suboptimal rinsing processes, dusty environments, and material and machine contamination. Highest Risk Priority Number (RPN) of 560 confirmed that human factors were the main cause of defects. Proposed improvements include installing dummy plates, adding a rinsing process, cleaning the transporter machine, closing the production area, and using clean gloves and work clothes. The implementation of these improvements proved to be effective, reducing the DPMO to 9583, increasing sigma to 3,84, and reducing dirty defects from 12% to 2,25%. Results of research prove how combining DMAIC and FMEA could significantly improve product quality. These findings can be used as a reference for implementing continuous improvement in electroplating services and other manufacturing sectors facing similar problems
