Abstract

Non-sterile M Handscoons are medical gloves to protect healthcare professionals from transmitting disease through direct patient contact. The handscoons come in boxes at 100 gloves per box. Among all consumable items stocked by Hospital X, located in Padang, the handscoons consumed the highest inventory costs. This paper aims to determine a better inventory policy for the Non-sterile M Handscoons. Better order quantity and reorder point were determined. Since the demand for the handscoon was probabilistic, the Monte Carlo simulation was used to determine the order quantity and reorder point to maximize service level and reasonable total inventory costs. The algorithm used to execute the simulation was presented and implemented as a spreadsheet-based Monter Carlo simulation. Four scenarios were compared, combining different order quantities and reorder points, including the hospital's current inventory control policy. A procedure with the mean of service level and total cost as the criteria for selecting the best scenario was presented. The Anderson-Darling Goodness-of-Fit test and Least Squares parameter estimation method showed that the monthly demand follows Weibull distribution with an estimated shape parameter  = 5.32 and scale parameter  = 262.06. The monthly demand mean was 242 boxes. Accordingly, using the Central Limit Theorem, the annual demand was approximately normally distributed, with a mean of 2,899 boxes and a standard deviation of about 178 boxes. The simulation results indicated that an inventory policy with an order quantity of 216 boxes and an order interval of 27 days is the most effective. This policy achieved a mean service level of 99.9 percent with an annual inventory cost of Rp179.35 million. In addition, the selected policy was estimated to guarantee a minimum service level of 94.7 percent and achieved a 100 percent service level with approximately 92 percent certainty. Compared with the status quo, adopting this policy increased the service level by approximately 19 percent, accompanied by a proportional increase in annual inventory costs.

Abstract

The traditional fisheries sector in Indonesia still faces various challenges in terms of operational efficiency and productivity, driving the need for innovative solutions to improve the performance of this sector. This study aims to analyze and improve the operational performance of traditional fishermen through the application of the Lean and Green Supply Chain Management (LGSCM) concept, using a mixed-method approach that combines quantitative and qualitative analysis. Data were collected through direct observation, in-depth interviews with 50 traditional fishermen, and measurement of operational parameters over a 6-month period. The results of the study identified significant waste in the traditional fisheries supply chain, including an average waiting time of 4.2 hours per trip, excess fuel consumption of up to 12 liters per trip, and a loss of 8.5 kg of catch per trip due to improper handling. The implementation of LGSCM which includes standardization of work processes, optimization of shipping routes, improvement of fish storage systems, and the use of appropriate technology has resulted in significant improvements. After the application of this concept, there was a reduction in waiting time to 2.3 hours per trip, a decrease in fuel consumption to 8.4 liters per trip, and an increase in marketable catch to 32.5 kg per trip. The conclusion of the study shows that the application of LGSCM has not only succeeded in increasing the efficiency and productivity of traditional fishermen's operations, but also contributed to reducing the environmental impact of fishing activities. This study recommends the need for ongoing training programs, increased infrastructure support, and the development of policies that support the adoption of LGSCM practices in the traditional fisheries sector to ensure the sustainability of its implementation and benefits in the long term.

Abstract

Product quality is a crucial factor in enhancing the competitiveness of the manufacturing industry, particularly in the Bottled Drinking Water (BDW) industry. This study aims to optimize the quality of bottled drinking water products through the Six Sigma approach in an effort to reduce product defect rates. The method employed is Six Sigma with the DMAIC (Define, Measure, Analyze, Improve, and Control) framework. The data used consist of product defect records collected over a three-month period, including broken bridge defects, tilted caps, standing caps, and overpressure defects. In the measure phase, defect rates, Defects Per Million Opportunities (DPMO), and sigma levels were calculated to evaluate the performance of the production process. The analyze phase revealed that broken bridge defects were the dominant type of defect based on Pareto diagram analysis, making them the primary focus for improvement efforts. Root cause analysis using a cause-and-effect (fishbone) diagram indicated that the main contributing factors originated from machine, method, and human aspects. Furthermore, in the improve phase, several corrective actions were proposed, including machine torque adjustment, operator training, implementation of Standard Operating Procedures (SOPs), and improvement of raw material quality. The control phase was conducted by establishing operational standards and process monitoring systems to ensure the sustainability of improvements. The results demonstrate that the implementation of Six Sigma provides a systematic solution for reducing product defects and continuously improving the quality of bottled drinking water products.

Abstract

This study aims to develop and empirically test a resource sustainability evaluation model for non-profit organizations based on an industrial management system perspective by integrating internal process integration and external marketing strategy. The object of this study is the Marvin Foundation, with respondents consisting of donors, active volunteers, and organizational partners. The study employs an explanatory quantitative approach with a cross-sectional survey design and purposive sampling technique, involving 100 respondents. Data analysis was conducted using Partial Least Squares–Structural Equation Modeling (PLS-SEM) with the assistance of SmartPLS software. The results indicate that internal process integration has a positive and significant effect on resource sustainability, with a path coefficient of 0.420, while external marketing strategy also shows a positive and significant effect, with a coefficient of 0.360. The coefficient of determination (R²) of 0.580 suggests that the model has moderate to substantial explanatory power. Furthermore, the predictive relevance value (Q²) of 0.34 indicates that the model possesses good predictive capability. These findings highlight that resource sustainability in non-profit organizations is not solely determined by external factors but is strongly influenced by the integration of internal organizational processes. This study contributes to the development of a resource sustainability evaluation model based on an industrial management system approach and provides practical implications for improving organizational effectiveness and long-term sustainability.

Abstract

PT XYZ is a company engaged in the processing of rubber into crumb rubber products, supported by various machines and equipment to achieve optimal productivity. One of the main machines in the production process is the dryer, which functions to reduce the moisture content in the product. The main issue identified is that the effectiveness of the dryer machine, as measured using the Overall Equipment Effectiveness (OEE) method, shows values of 84%, 84%, and 82% during August–October 2025, which are below the world-class standard of 85%. Analysis using the Reliability Centered Maintenance (RCM) and Failure Mode and Effect Analysis (FMEA) methods indicates that critical components such as chain, box rail, and box wheel have a high risk of failure based on their Risk Priority Number (RPN) values, thus requiring special attention in determining maintenance actions. The application of the Reliability Centered Maintenance (RCM) method identifies the most appropriate maintenance actions for critical components through the task selection process based on the characteristics of each failure mode. These results indicate that prioritizing maintenance on critical components can reduce potential failures and improve machine effectiveness in the production process.

Abstract

The Small and Medium Industries (SMEs) sector in Batam City, particularly in the food processing sub-sector, plays a strategic role in supporting regional economic growth and job creation. However, many SMEs still face production quality problems related to sanitation, non-ergonomic work environments, weak process control, and low worker discipline in implementing hygiene standards. These conditions may reduce product quality, productivity, and consumer trust. This study aims to analyze priorities for improving production process quality through the implementation of Good Manufacturing Practices (GMP) and Work Improvement in Small Enterprises (WISE) in food-processing SMEs in Batam City, as well as to develop a practical priority improvement model that can be used as a reference for similar enterprises. This research employed a case study approach using observation, interviews, documentation, and literature review as data collection techniques. GMP and WISE indicators were structured into criteria and sub-criteria, then analyzed using the Analytical Hierarchy Process (AHP) to determine the ranking of improvement priorities. The results show that the main priority criterion is Hygiene and Sanitation Program (46%), followed by Production Process Control (23%), Packaging, Storage and Material-Equipment Handling (11%), Organization of Work (11%), Workplace Design (6%), and Welfare Facilities (3%). At the sub-criteria level, the most dominant factors are First Aid Equipment (58%), Pest Prevention and Control Program (46%), Employee Habits (46%), and Documentation and Record Keeping (39%). The consistency ratio met the acceptable threshold, indicating that the judgments were consistent and reliable for decision-making purposes. The outputs of this study include a priority map for production quality improvement based on GMP-WISE and an AHP-based decision framework that helps SMEs allocate limited resources to the most critical improvement areas. The contribution of this study to knowledge development lies in strengthening an integrative approach that combines food safety, work ergonomics, and decision support systems to enhance the competitiveness of food-processing SMEs in a systematic, measurable, and applicable manner

Abstract

This study aims to analyze and control the quality of can products by identifying the main causes of defects and evaluating the capability of the production process. The problem faced by the company is the high defect rate exceeding the established standards, particularly dominant defects such as scumming. The methods used in this study are Failure Mode and effect Analysis (FMEA), the Plan-Do-Check-Act (PDCA) cycle, and the process capability index (Cpk). Data were collected through observation, interviews, and documentation during a specific production period. The analysis begins with identifying dominant defects using a Pareto diagram, followed by FMEA to determine the priority of failure causes based on the Risk Priority Number (RPN). Furthermore, continuous improvement is implemented through the PDCA cycle, which includes planning corrective actions, implementation, evaluation, and process standardization. The final stage involves calculating the Cpk index to assess the process capability in meeting company specification limits. The results indicate that several main defect causes with the highest RPN values require immediate improvement. The implementation of PDCA contributes to reducing defect rates and improving process control. However, the obtained Cpk values show that the production process is not yet fully stable and still requires further improvement. Therefore, improvements should focus on critical factors such as machine settings, operator skills, and operational procedures.
