Evaluasi Kinerja dan Aksesibilitas SIA UIN Sumatera Utara Menggunakan Automated Software Testing

Web-based Academic Information Systems (AIS) serve as essential services in higher education institutions; therefore, their performance and accessibility need to be evaluated regularly. This study aims to measure the performance and accessibility of the AIS Dashboard at UIN Sumatera Utara, identify technical issues affecting these aspects, and formulate recommendations for improvement. This research employed a quantitative experimental approach based on automated software testing using Google Lighthouse in Desktop and Mobile modes. Testing was conducted on October 15, 2026, during peak academic hours, with three repetitions (K = 3) for each mode. The scores were averaged and descriptively analyzed based on Lighthouse criteria. The results showed an average Performance score of 96.67 in Desktop mode (good category) and 84.00 in Mobile mode (requiring improvement). Accessibility obtained the lowest scores, at 58.33 in Desktop mode and 67.00 in Mobile mode. These findings indicate the need for further examination of interface accessibility, particularly color contrast ratios, accessible labels (aria-labels) on interactive elements, and the consistency of heading hierarchies. Best Practices scores reached 97.33 in Desktop mode and 88.33 in Mobile mode, while SEO scored 85.00 in both modes. Based on these findings, the study recommends compressing images using the WebP format, minifying CSS and JavaScript files, improving interface accessibility attributes and structure, and implementing browser caching and a Service Worker. This study provides an objective basis for AIS administrators to improve the quality of digital services by making them faster and more inclusive.
