Abstract

Penelitian ini mengeksplorasi dampak integrasi ChatGPT, sebuah kecerdasan buatan berbasis teks, dalam konteks pendidikan modern. Dengan melibatkan 215 peserta dari berbagai pemangku kepentingan, studi ini menyelidiki pengaruh interaksi dengan ChatGPT terhadap keterampilan kognitif, seperti berpikir kritis dan pemecahan masalah. Hasil menunjukkan variasi persepsi terhadap dampak ChatGPT, dengan beberapa peserta melaporkan peningkatan yang signifikan sementara yang lain merasakan dampaknya terbatas. Kesimpulan menekankan pentingnya penggunaan teknologi kecerdasan buatan secara bertanggung jawab dalam pendidikan, sambil menyadari keterbatasan metodologis dan memperhitungkan perspektif yang beragam dalam mengoptimalkan pengalaman belajar.

Abstract

This study develops and evaluates an Android-based attendance system integrating dual-factor authentication using dynamic QR codes and GPS geofencing to prevent proxy attendance in higher education. The system was developed using the Waterfall model and evaluated through quantitative experiments measuring response time, GPS accuracy drift, and security robustness via Black-Box testing. Results show high efficiency with an average response time below 1.5 seconds. GPS validation achieved an average drift of 4.2 meters outdoors and 12.5 meters indoors, remaining within the 30-meter geofencing threshold. The system successfully rejected unauthorized attempts, including out-of-range scans and fake GPS spoofing. These findings demonstrate that combining dynamic QR codes with GPS validation significantly improves attendance authenticity and system reliability compared to single-factor methods. The study provides empirical evidence of a robust and scalable solution for secure mobile-based attendance systems in higher education.
