Clustering Prestasi Akademik Lulusan Menggunakan Metode K-Means
Prestasi akademik merupakan salah satu indikator penting untuk mengukur keberhasilan seorang mahasiswa dalam menyelesaikan studinya di perguruan tinggi. Prestasi ini dapat dilihat dari berbagai aspek, seperti lama studi dan Indeks Prestasi Kumulatif (IPK). Analisis ini digunakan untuk meningkatkan kualitas Pendidikan pada Perguruan Tinggi itu sendiri, serta untuk membantu Mahasiswa dalam mencapai prestasi yang optimal. Penelitian ini bertujuan untuk melakukan clustering prestasi akademik lulusan pada Universitas Ichsan Gorontalo untuk Tahun Akademik 2023/2024 semester Ganjil dengan menerapkan metode K-Means.
