Abstract

Minat baca mahasiswa merupakan salah satu indikator penting dalam menunjang kualitas akademik di lingkungan perguruan tinggi. Penelitian ini bertujuan untuk menganalisis segmentasi minat baca mahasiswa Universitas Islam Negeri Sumatera Utara (UINSU) menggunakan metode K-Means Clustering. Data dikumpulkan melalui kuesioner yang mencakup frekuensi membaca, jenis bacaan yang diminati, waktu yang dihabiskan untuk membaca, serta motivasi membaca. Metode K-Means digunakan untuk mengelompokkan mahasiswa ke dalam beberapa segmen berdasarkan kesamaan karakteristik minat baca. Hasil analisis menunjukkan bahwa mahasiswa dapat diklasifikasikan ke dalam tiga klaster utama, yaitu: (1) kelompok dengan minat baca tinggi, (2) kelompok dengan minat baca sedang, dan (3) kelompok dengan minat baca rendah. Segmentasi ini diharapkan dapat membantu pihak kampus dalam merancang program peningkatan literasi yang lebih terarah dan sesuai dengan karakteristik masing-masing segmen mahasiswa.

Abstract

Cryptography is a fundamental field in data security; however, it is often considered difficult for beginner students due to its abstract and mathematical nature. Previous studies indicate that learning Caesar Cipher is commonly conducted through theoretical approaches or desktop-based applications with limited interactivity and accessibility. Therefore, this study aims to develop a web-based Caesar Cipher encryption simulation application as an interactive learning medium. The system was developed using the prototype method, while functional testing was conducted using the black box testing approach. The effectiveness of the application was evaluated through primary data collected through questionnaires distributed to students. The results show that before using the application, 82.4% of students were at low to moderate levels of understanding, whereas after using the application, 100% of students reached a high level of understanding. These findings indicate that the web-based Caesar Cipher simulation application is effective in improving students’ understanding of fundamental cryptographic concepts prior to studying more advanced data security algorithms
