Abstract

Suboptimal production facility placement is often the root of inefficiency problems, ranging from unsmooth material flow to inflated operational costs. This study aims to redesign the production line Layout of the chair division at PT XYZ using the Systematic Layout Planning (SLP) approach. Data were collected through field observations and various analytical tools such as From To Chart, Priority Scale Table, Activity Relationship Chart which were then verified through FlexSim simulation with quite significant results. The new Layout succeeded in reducing material movement distance from 1,042.51 meters to 760.64 meters (down 27.04%), speeding up movement time from 2,578.38 seconds to 1,901.60 seconds (27.04% efficiency), and reducing material handling costs from Rp2,767,220.62 to Rp2,141,482.78 or by 22.61%. These findings prove that the structured rearrangement of production facilities is able to encourage workflow efficiency and smooth production processes as a whole at PT XYZ.

Abstract

This study aims to design an ergonomic soybean washing machine to improve the efficiency and productivity of the tempeh production process at UD. XYZ. The main problem faced by the company is the low capacity of soybean washing which is still done manually, causing delays in the production flow and becoming a bottleneck in the production system. The study was conducted with an ergonomic approach through anthropometric measurements of operators as a basis for designing the machine to suit user needs and provide work comfort. The anthropometric data obtained were then tested using adequacy tests and data uniformity tests to ensure the validity and feasibility of the data. The machine design is based on the 95th percentile so that it can be used by most operators. In addition, the study also used the POSPAC method to analyze productivity levels before and after the implementation of the soybean washing machine. The research results show that the anthropometric data meets the requirements of adequacy and uniformity, making it suitable for use as a design reference. The designed machine can increase soybean washing capacity from 25 kg to 50 kg in a single process, significantly improving production efficiency and smoothness. Productivity analysis shows an increase in most productivity indicators, although capital productivity decreased due to the initial investment in machine procurement. Furthermore, production capacity has increased to meet and even exceed market demand. Thus, the ergonomic design of the soybean washing machine has proven effective in improving the performance and productivity of the tempeh production system at UD. XYZ.

Abstract

PT Group Cemerlang Plastindo continues to experience product rejection in the plastic pallet production process using the Sound 1800 injection molding machine. This condition reduces product quality, increases material waste, and decreases production efficiency, indicating the need for effective quality control and process parameter optimization. Objective: This study aims to identify the dominant types of product rejection, analyze the factors causing product defects, and determine the optimal combination of process parameters to reduce the reject rate of plastic pallet products. Methods: This study employed a quantitative approach using the Taguchi method supported by Statistical Quality Control (SQC) tools, including check sheets, histograms, Pareto diagrams, control charts, and fishbone diagrams. Data were collected from production records between January 2025 and January 2026, direct observations, and interviews with production personnel. Results: The results showed that 2,499 products were rejected from a total production of 107,669 plastic pallets. The dominant defects were short shot (998 units), uneven coloring (708 units), and crack (505 units). The application of the Taguchi method reduced the number of rejected products from 383 units to 332 units, corresponding to a 0.39% reduction in the reject ratio, indicating that process parameter optimization improved production quality. Implications: The findings demonstrate that integrating Statistical Quality Control tools with the Taguchi method provides an effective approach for identifying dominant defects, determining optimal process parameters, reducing production waste, and improving product quality consistency. The recommended parameter settings can serve as a practical reference for quality improvement in industrial injection molding operations. Originality: The originality of this study lies in the integration of Statistical Quality Control tools and the Taguchi method to optimize process parameters for plastic pallet production on the Sound 1800 injection molding machine using actual industrial production data. This integrated approach provides a practical quality improvement strategy for reducing the three dominant rejection types under real manufacturing conditions.

Abstract

PT XYZ is a packaging printing company whose production process highly depends on machine performance. One of the critical machines is the Gluer JK-1000, which is used in the folding and gluing stages of packaging production. This study aims to evaluate the effectiveness of the Gluer JK-1000 machine using the Overall Equipment Effectiveness (OEE) method and to determine an appropriate maintenance strategy through the Reliability Centered Maintenance (RCM) approach. The study utilized operational and production data collected from August to December 2025. The results showed that the Availability Rate, Performance Rate, and Quality Rate were 90.97%, 89.10%, and 87.40%, respectively, resulting in an OEE value of 70.84%, which is below the 85% standard established by the Japan Institute of Plant Maintenance (JIPM). Six Big Losses analysis revealed that Reduced Speed Losses and Setup and Adjustment Losses were the dominant sources of productivity loss, contributing 15.47% and 8.11%, respectively, with a cumulative contribution of 81.95%. FMEA identified critical components consisting of the Feeding Belt (RPN 252), Sensor Gluing (RPN 245), Roller Gluer (RPN 224), and Side Lay Register (RPN 210). Based on the RCM analysis, maintenance recommendations were developed through Time Directed Maintenance and Condition Directed Maintenance approaches, with preventive maintenance intervals determined according to component reliability analysis. The findings can be used as a basis for improving machine reliability and reducing downtime risk in the production process.

Abstract

PT XYZ is a packaging printing company facing quality problems due to a high defect rate in its printing process. This study aims to identify dominant defects, determine the root causes of defects, and develop improvement recommendations to enhance product quality. The methods employed were Seven Tools consisting of check sheets, stratification, histograms, Pareto diagrams, p-control charts, and fishbone diagrams, combined with Failure Mode and Effects Analysis (FMEA) and the 5W+1H approach. The results showed that total defects during July–December 2025 reached 4,320,066 units out of 166,435,973 units produced. The dominant defects were out-of-range color defects (38.39%), dirty printing defects (31.06%), and incorrect design code placement (18.75%), contributing 88.14% of total defects. The p-control chart indicated that the process was not statistically controlled because several observations exceeded the control limits. Improvement recommendations include implementing boundary samples, standardized ink mixing procedures, first product inspection, visual marking, and visual cleaning SOPs to reduce defect levels and improve printing quality.
