Abstract

The fingerprint-based attendance system at Universitas Teknologi Digital still faces operational limitations, including physical queues, manual monthly recapitulation, limited attendance points, and potential inconsistencies in attendance records. Mobile attendance can improve efficiency, but it also introduces location spoofing risks and maintainability issues when developed using a monolithic structure. This study aims to implement a geo-tagged mobile attendance application using Pragmatic Clean Architecture and evaluate its maintainability compared with a monolithic prototype. The research applies Agile Scrum, object-oriented design, native Android implementation, Progressive Web App access, server-side validation, anti-spoofing testing, and static code analysis using Android Studio Narwhal on Java source code. Location validation is supported through Android mock-location detection, heuristic validation on the PWA layer, and server-side validation. In a limited anti-spoofing test using Fake GPS, the system rejected or marked suspicious locations in 5 out of 5 attempts on both native Android and PWA access, although PWA validation required a longer checking process and remains heuristic. Maintainability evaluation shows that the average Lines of Code per method decreased from 36.26 to 16.85, equivalent to a 53.5% reduction. The average Cyclomatic Complexity decreased from 2.32 to 1.78, equivalent to a 23.27% reduction and remaining in a low-risk category. These findings indicate that the proposed system improves attendance validation and provides an initial indication of a more analyzable, modifiable, and testable code structure. However, LOC and Cyclomatic Complexity are treated as initial maintainability indicators, not a complete representation of all ISO/IEC 25010 maintainability sub-characteristics.
