Abstract

The problem of determining catering delivery routes at UMKM Vfoodia in Medan City is still carried out manually and relies heavily on couriers’ experience, which may lead to inefficiencies, especially in cases of courier replacement and limited delivery time windows. This condition results in delivery delays and difficulties for couriers in understanding customer locations and delivery sequences. This study aims to develop a catering delivery route determination system based on Geographic Information System (GIS) using the Dijkstra algorithm. The system is developed as a web-based application accessible via Android devices to support both administrative and courier activities. GIS is utilized to visualize customer locations and road networks on a digital map, while the Dijkstra algorithm is applied to compute the shortest route between two points. In daily delivery operations involving multiple destinations, the Dijkstra algorithm is executed repeatedly, where the destination point is updated each time a customer delivery is completed. The system is integrated with the OpenRouteService API to obtain distance and travel time estimations and is equipped with a caching mechanism to reduce repetitive API calls. The contribution of this research lies in the application of the standard Dijkstra algorithm in a repetitive manner within a GIS-based system to support structured multi-destination catering delivery at the UMKM scale. Experimental results show that the system is able to generate the shortest delivery route with a minimum distance of 6.0 km in the test scenario and helps make the delivery process more organized and easier for couriers to understand. Therefore, the proposed system improves delivery efficiency and enhances the quality of catering delivery services at UMKM Vfoodia.

Abstract

As educators, functional position promotion (JaFung) serves as a means of advancing teachers’ careers as well as an indicator of their success in meeting established quality standards. However, in practice, this process still faces several challenges, such as teachers having difficulty monitoring the progress of their submitted proposals and institutions needing to contact teachers individually when issues arise. These problems indicate the absence of integration between progress monitoring and communication within a unified system. This study aims to propose a system model that integrates monitoring, communication, and RBAC-based security mechanisms. The Role-Based Access Control (RBAC) mechanism is used as a framework for managing interactions among actors across institutions and is designed using a scenario-driven role engineering approach to produce an RBAC model that adheres to the principle of least privilege. The system development method employed in this study is the Software Development Life Cycle (SDLC) using the Waterfall model. The results of black-box testing show that the developed system operates in accordance with its specifications and fulfills functional requirements. Access violation testing involving 10 unauthorized access attempts resulted in a violation rate of 0%, indicating that all unauthorized access was successfully prevented by the system. In addition, there was a 37.21% reduction in the number of permissions in the RBAC-implemented system, demonstrating the application of the least privilege principle. The proposed system not only facilitates document management and proposal progress monitoring but also enhances security and ensures more structured access management in the functional position promotion process.
