Abstract

Abstract Painting quality control (PDI Painting) at PT XYZ plays an important role in ensuring the final quality of products. The purpose of this study is to identify the most common types of defects and their causes in the Painting process. The research was conducted over two months using direct observation, interviews, and documentation, and analyzed using Statistical Quality control (SQC) and Root Cause Analysis (RCA) methods, including Checksheets, Pareto diagrams, fishbone diagrams, and the 5 Whys technique. The results showed that the most dominant defect was pinholes (18.43%), followed by thin paint, uneven paint, and overspray. The main contributing factors included a lack of operator skills, uneven paint mixing, and unstable spray pressure. The recommendations provided were regular operator training, the use of paint thickness measuring tools, and an automatic paint mixing system to reduce the defect rate. Overall, this study confirmed that defects in the PDI Painting stage had a significant impact on production efficiency and rework costs. By integrating the SQC method to identify defect patterns and RCA to trace the root causes, an understanding of the factors affecting quality was obtained. The practical implications of this study are the need to improve operator competence, standardize work methods, and ensure consistent machine maintenance. By implementing the proposed improvements, PT XYZ has the potential to reduce the number of defects by 20–30% and improve product quality consistency.

Abstract

Every region in Indonesia has its own unique way of celebrating events, whether happy or sad, in the form of celebrations. Celebrations are also a means of introducing culinary treasures that are closely linked to the culture and local wisdom of a region. These culinary treasures are accompanied by the growth of the catering business. The main focus of the culinary aspect is ice cream. The challenge lies in the distribution and delivery from the production site to the event location to maintain the temperature and keep it cold. This study designed a cooling box using the Axiomatic Design method. Axiomatic Design is a design method in which decision-making and perspectives are based on consumer desires. Therefore, this study focuses on describing and translating consumer needs into abstractions in the form of design functions, which are then linked to parameters. Data collection was conducted using open questionnaires and interviews with ice cream entrepreneurs. The results of the study focused on 1) the design of handles on the cooling box located on the sides for lifting into vehicles; 2) the design of cooling box locks to keep the lid tight and easy to open; 3) the design of the coating on the walls of the cooling box to maintain the temperature of the ice cream. The validity test results showed a p-value greater than 0.05 (p > 0.05), indicating that there was no difference between the proposed design and the needs of ice cream entrepreneurs.

Abstract

The initial facility layout condition in the Seat Division of PT XYZ remains suboptimal, characterized by the accumulation of seats in the assembly and finishing area and an excessive material transfer distance, reaching 86.88 meters. This situation results in cramped production space and hinders overall work efficiency. This study aims to analyze the current facility layout and provide a layout improvement proposal to ensure the production process is both effective and efficient. The Activity Relationship Chart (ARC) method was adopted to analyze the functional closeness relationships among the seven departments, integrating material flow requirements with non-material factors such as noise and supervision. The resulting ARC matrix was then processed using the BLOCPLAN software to design three alternative layout proposals. The efficiency of each proposal was quantitatively evaluated by calculating the Euclidean Distance between department centroids for the main process flow. The comparative analysis of material transfer distance showed that Proposed Layout Two is the best alternative, with a total distance of 57.56 meters (measured using the Euclidean Distance method). This proposal is capable of reducing the material transfer distance by 29.32 meters, or approximately 33.7%, from the initial layout. This layout improvement is expected to optimize space utilization, minimize material accumulation, and streamline the workflow.

Abstract

This study aims to analyze and enhance the quality of the pipe sales process by implementing the Seven Quality Control (QC) Tools combined with the Plan, Do, Check, Action (PDCA) approach. The research was motivated by a high defect rate and frequent customer complaints that negatively affected service quality and sales performance. A descriptive quantitative method was applied, using data collected from observations, interviews, and one-year sales reports. The analysis utilized seven quality control instruments: check sheet, histogram, Pareto chart, cause-and-effect (fishbone) diagram, scatter diagram, control chart, and flowchart to identify the root causes of product defects. The results revealed that the most common defects were bent pipes, uneven diameters, and cracks during cutting, which were primarily caused by human factors, work methods, and material quality. The PDCA cycle implementation effectively reduced defect levels, improved compliance with standard procedures, and promoted a culture of continuous improvement. Consequently, the integration of Seven QC Tools and the PDCA cycle has proven effective in improving product quality, operational efficiency, and customer satisfaction sustainably.

Abstract

The cooling fan in a geothermal power plant’s cooling tower is vital for maintaining temperature stability, and its performance directly affects efficiency and reliability. This study evaluates the cooling fan at PT XYZ using the Overall Equipment Effectiveness (OEE) method and identifies operational losses through the Six Big Losses framework. Research was conducted via field observation, interviews with technicians and operators, and data collection on operating time, downtime, performance, and cooling quality. Results show Availability at 98.75%, Performance at 97.21%, and Quality at 88.89%, producing a total OEE of 90.83%, which surpasses the world-class benchmark of 85%. Despite this strong performance, Six Big Losses analysis revealed significant issues from Defect/Process Losses and Reduced Speed Losses, both impacting cooling quality. These findings indicate that while the cooling fan’s effectiveness is very good, improvements are still needed to enhance quality and operational stability. Practically, the study provides guidance for companies to design more targeted maintenance strategies, while academically, it serves as a reference for further research on industrial equipment effectiveness using OEE and Six Big Losses.

Abstract

This study aims to implement the Six Sigma method in the carton packaging production process using the Wraparound machine at PT. XYZ to enhance process capability and reduce defect levels. The research adopts the DMAIC (Define, Measure, Analyze, Improve, Control) approach. Initial measurements in the Measure stage were conducted using DPU, DPO, DPMO, and sigma level indicators, while the Control stage was used to evaluate the performance after improvements. Pareto analysis and fishbone diagrams were applied to identify dominant defects and their root causes. The findings show that open carton folds and misaligned carton folds were the dominant defects, with an initial sigma level of 3.97 and a DPMO of 6,784. After improvement actions such as machine setup standardization, preventive maintenance implementation, material quality enhancement, and operator training, the sigma level increased to 4.13 and the DPMO decreased to 4,281. The average defect rate also improved from 4.07% to 2.57%. These results indicate that the Six Sigma method is effective in improving quality, reducing defect rates, and optimizing the performance of the Wraparound machine at PT. XYZ.

Abstract

This study aims to determine the optimal allocation of planting areas for rice (X₁) and corn (X₂) in order to maximize agricultural profit in East Java Province. The agricultural sector in this region faces significant limitations in key resources, particularly land, fertilizer, and labor, which necessitate efficient and quantitatively grounded management strategies. This study employs a Linear Programming approach using the graphical method, based on a mathematical model developed from simulated data representing regional agricultural conditions. The results indicate that the optimal land allocation consists of 60 hectares for rice and 40 hectares for corn, generating a maximum profit of IDR 1,300,000,000. The constraint analysis reveals that land and fertilizer constraints act as binding constraints at the optimal solution, while the labor constraint is non-binding. This finding implies that further profit improvements cannot be achieved by increasing labor input, but rather by expanding or optimizing land use and fertilizer availability. Overall, this study provides a clear analytical framework to support decision-makers in formulating more efficient land allocation policies and improving agricultural productivity through optimal resource utilization

Abstract

Network security in hospital environments represents a critical challenge due to high traffic volumes and the sensitivity of medical data. This study aims to evaluate the performance of a Snort-based Intrusion Detection System (IDS) in detecting network attacks within the Mitra Keluarga Hospital infrastructure. The evaluation was conducted using an experimental approach by deploying Snort on a monitored server segment and performing simulated attacks, including port scanning, SSH brute force, ICMP flooding, and SQL injection. System performance was assessed based on detection respone time, detection rate, and alert consistency. The results demonstrate that the IDS successfully detected all tested attack scenarios, achieving respone times ranging from 0.4 to 1 second and a detection rate of 100% under the experimental conditions. However, potential false positives were identified in internal ICMP traffic, indicating the need for threshold parameter adjustment. These findings indicate that a Snort-based IDS is effective as an early attack detection mechanism for hospital networks and can be further enhanced through integration with centralized monitoring systems to support informed network security decision-making
