Current digital landfill monitoring systems suffer from unstructured data flow and poor access control, which may weaken data precision, security, and decision-making. A digital weighing system is already used at the Supit Urang Landfill in Malang, Indonesia, to record incoming waste. However, operational inefficiencies persist, especially in how users manage and share information. Therefore, a smart weighing system with structured data flow and secure access control is needed. This study aims to increase the reliability and security of the system by looking at the data flow and the user privilege system. The research process involves identifying the user roles and system requirements through a Use Case Diagram, followed by Role-Based Access Control (RBAC) in order to clearly define access privileges. These data access control rules and roles are then conveyed into specific processes in Data Flow Diagrams, illustrating the flow of data between layers and user activity control. The system was evaluated using access accuracy metrics and simulated misuse scenarios through negative testing. Results show that integrating access control with structured data flow enhances data integrity and user accountability. The system achieved an Access Accuracy Rate (AAR) of 93.3% and an Access Violation Rate (AVR) of 6.3%, indicating robust enforcement of permission boundaries. © 2025 IEEE.
