Abstract

The efficiency of the queuing system at a Public Fuel Filling Station (SPBU) is one of the crucial factors in maintaining smooth operations and increasing customer satisfaction. This study specifically analyzes the performance of the queuing system with a single channel single phase model at a gas station using a simulation approach assisted by Arena Simulation Software. The main focus of this study is to evaluate a number of performance indicators, such as average customer waiting time, queue length, server utilization rate, and service capacity that can be achieved under existing conditions and after the improvement scenario is implemented. Primary data was collected through direct observation in the field during peak hours, which were then processed and analyzed using probability distributions to model customer arrivals and service times. The simulation results show that the existing system has a very high server utilization rate, approaching 100%, indicating a potential risk of overload, although the average customer waiting time is relatively minimal. However, this performance can only be maintained under certain conditions and is at risk of decreasing significantly if there is a surge in customers beyond predictions. Simulation of the improvement scenario by significantly increasing the number of servers and operators succeeded in reducing the server utilization rate to the optimal level, shortening service time, and increasing the service capacity of the gas station. This proves that managerial intervention through the addition of service resources is a strategic step to increase operational efficiency.

Abstract

As public awareness continues to grow regarding the importance of zakat, infaq and sadaqah (ZIS) as tools for social and economic welfare in Indonesia, there is an increasing need for innovation in how these charitable contributions are managed. One promising solution is the development of a mobile application that uses chatbot technology to make the process of giving and managing ZIS more efficient, transparent and user friendly. This study focuses on designing and building such a mobile app, using the waterfall model for software development. The process includes defining requirements, designing the system, analyzing the features, implementing the chatbot, and testing the application. The app is built to provide an interactive experience that helps users easily perform ZIS-related transactions, while also offering personalized information based on their needs. Testing results show that the app successfully supports essential functions like user registration, zakat payment, and access to ZIS information. It was also tested for compatibility and UI stability begin with Android 10 (Q) and above. While earlier versions such as Android 8 and 9 pose risks related to SDK support and performance, versions Android 12 to 14 demonstrate optimal performance and system stability. Android 15, still in beta, shows positive early results but requires further testing due to its ongoing development and potential SDK changes on multiple devices to ensure performance across different platforms. The findings indicate that the app runs smoothly, is easy to use, and is accessible to the broader community. Overall, this research presents a meaningful contribution to the modernization of ZIS management in Indonesia by leveraging digital technology to better serve the public.
