Abstract

Foodbank is an organization that obtains food from donor organizations and individuals, proceeds the donated food products at storage facilities and distributes them to the end users, either directly or indirectly via charitable institutions. Foodbanks have been developed in several countries to tackle food waste and hunger problems. This research uses the case of FoodCycle Indonesia (FCI) as one of the food banks in Indonesia that has been in operation since 2017. The purpose of this study is to analyze the sustainability of FCI using system dynamics simulation to identify the factors that influence its sustainability. We develop the initial model based on literature and modify it according to interview results with representatives from FCI and its two partners (charitable organizations that redistribute the donated food to beneficiaries). The model consists of partners, wedding partners, food redistribution, transportation cost, community, volunteers, beneficiaries, and food balance subsystems. Based on the simulation results it can be concluded that FCI will be sustainable as long as the growth of the food supply is constant, and the organization has the financial ability to support the distribution of donated food to the beneficiaries.

Abstract

Business process improvement is a well-known technique for organizations to identify processes that enhance business performance. This study aims to analyze and improve business processes in the company's principal operational processes that are directly related to controlling service requests for assistance with traffic problems on the toll road (Command Center), specifically in communication and handling requests for assistance and complaints from users of one of the toll road operators in Indonesia. Research is conducted by identifying existing processes, the underlying causes of existing problems, and analyzing business processes using the Business Process Improvement methodology and the Bizagi Modeler with Process Modeling and Notation (BPMN). An improvement within this approach is thus examined in a particular scenario. The as-is and to-be processes are measured using a technique of improvement design called the ESIA approach, consisting of four steps: eliminate, simplify, integrate, and automate. The result of the integration of Command Center services can decrease the response time for assisting requests from toll road users and enhance cost-effectiveness, improving customer satisfaction and the overall quality of toll road service.

Abstract

Background: The flexible packaging industry is experiencing significant growth, requiring companies to improve efficiency by reducing defects and minimizing the cost of poor quality (COPQ). Effective quality control is crucial to maintaining competitiveness and reducing waste. This study focuses on assessing and improving quality control in an Indonesian flexible packaging company, XYZ, using the Six Sigma methodology. Methods: The research adopts the Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) approach to identify defects and propose solutions. Data collection includes statistical analysis, historical records, and interviews with company sources. The study specifically examines defects in the printing process, which accounts for 79% of total defects based on the 80/20 principle. The Failure Mode and Effects Analysis (FMEA) model is applied to identify root causes and develop recommendations for improvement. Findings: The study identifies multiple factors contributing to printing defects, such as register shifting, film scratching, color inconsistencies, ink transfer issues, and ink spots. Operator performance and machine-related issues are found to be the dominant causes of defects. Implementing the recommended quality control improvements can potentially reduce defect-related costs by 48%, translating to estimated cost savings of IDR 114,734,847 during the study period. Conclusion: This research confirms the effectiveness of Six Sigma in reducing defects and improving production efficiency in the flexible packaging industry. However, limitations include restricted access to ERP data, reliance on interviews and historical records, and the inability to evaluate the implementation of control measures. Novelty/Originality of this article: This study contributes to the literature by applying Six Sigma in a flexible packaging industry context in Indonesia, demonstrating its potential for substantial cost savings. Unlike previous studies, it emphasizes the human factor in quality control and suggests a systematic approach to defect reduction.

Abstract

​​​Background: The rapid development of the automotive industry requires an efficient production system to minimize costs and optimize resources. PT XYZ, an automotive component manufacturer, previously relied on a push production system based on demand forecasts. However, discrepancies between forecasted and actual demand led to excess inventory and increased storage costs. To address this issue, a hybrid push/pull production system was introduced, aiming to balance inventory levels while maintaining production efficiency. Methods: This study employs a discrete event simulation method using Arena software to analyze the impact of implementing a hybrid push/pull production system at PT XYZ. The research utilizes company data from October 2016 to compare the efficiency of different production scenarios. Findings:  Findings indicate that adopting a hybrid push/pull production system significantly reduces inventory costs while preventing backorders. The system modifies the upstream process by transitioning from forecast-based production to a pull system that aligns with actual demand. Meanwhile, the push system remains in use for raw materials and semi-finished components to ensure production continuity. Additionally, worker and machine utilization decreased, allowing the company to reallocate resources for other product lines, thereby enhancing production capacity. Conclusion: The study concludes that implementing a hybrid push/pull production system provides PT XYZ with a competitive advantage by reducing operational costs without compromising demand fulfillment. However, this system requires careful inventory tracking and employee adaptation. In the long run, reduced storage costs lead to substantial savings. Novelty/Originality of this article: The novelty of this research lies in its application of hybrid push/pull production to an SME automotive manufacturer in Indonesia, demonstrating its effectiveness in reducing costs and improving resource utilization.
