Abstract – The Unified Campus Service Hub is a mobile application designed to simplify and centralize campus service management in educational institutions. In many colleges, services such as complaint registration, leave approval, lab equipment booking, event registration, hostel requests, and notice announcements are handled through manual processes or separate systems, leading to delays, lack of transparency, and difficulty in tracking requests. The proposed system provides a unified digital platform where students can submit service requests and track their status through a mobile application. Staff members can review, approve, or reject requests, while administrators monitor overall activities using dashboards and reports. The system is developed using Flutter for the mobile interface and Firebase for authentication and cloud database management. A machine learning model integrated through Flask is used to automatically classify complaint priority levels. The platform improves efficiency, transparency, and communication between students, staff, and administrators while reducing manual administrative workload.

1. INTRODUCTION

   Educational institutions manage a variety of campus services such as complaint registration, leave approval, laboratory equipment booking, event registration, hostel service requests, and notice announcements. Traditionally, these services are handled through manual processes such as paper forms, physical registers, or different standalone applications maintained by separate departments.

   These traditional approaches often create several operational challenges. Manual record keeping can lead to data loss, delays in approvals, and difficulty in maintaining accurate records. Students may find it difficult to know the status of their submitted requests, and staff members must spend additional time verifying and processing each request manually.

   Another major issue is the lack of a centralized communication system between students, staff, and administrators. Notices and important announcements are often distributed through notice boards or messaging platforms, which may not always reach every student on time. This leads to poor communication and inefficient service management within the campus environment.

   In addition, service requests such as complaints or maintenance issues may remain unresolved for long periods due to the absence of a proper tracking system. Without a digital monitoring mechanism, administrators find it difficult to analyze which departments receive the most complaints or which issues require urgent attention.

   With the rapid growth of digital technologies, mobile applications have become an effective solution for improving service accessibility and communication in educational institutions. A well-designed mobile platform can provide a centralized system where multiple campus services can be managed efficiently in a single application.

   A unified digital platform allows students to submit service requests directly from their mobile devices and track the status of their requests in real time. Such a system can also help staff members to review requests quickly and update their status without relying on manual documentation.

   Modern cloud technologies further enhance the efficiency of such systems by providing real-time data synchronization and secure data storage. Platforms such as Firebase offer scalable cloud-based services that support authentication, database management, and real-time updates, making them suitable for mobile application development.

   Mobile development frameworks like Flutter enable developers to build responsive and user-friendly applications that can run on multiple devices with high performance. This allows educational institutions to deploy a single mobile

   solution that can be accessed by students, staff, and administrators.

   Another emerging technology that can improve service management is machine learning. By analyzing complaint descriptions submitted by students, machine learning models can automatically classify the priority level of issues. This helps staff members identify urgent problems and address them faster.

   In the proposed system, a machine learning model integrated using the Flask framework analyzes complaint text and predicts priority levels such as low, medium, or high. High- priority complaints can trigger alerts for staff members, ensuring faster response to critical problems.

   Therefore, the proposed system, Unified Campus Service Hub, aims to provide a centralized mobile application that integrates multiple campus services into a single platform. The system improves transparency, reduces administrative workload, enhances communication, and ensures efficient campus service management.
