utama dalam klasifikasi data medis, khususnya ada kasus penyakit diabetes.&#13;
Kondisi ini menyebabkan model klasifikasi cenderung lebih fokus pada kelas&#13;
mayoritas, sehingga kemampuan dalam mendeteksi pasien diabetes sebagai kelas&#13;
minoritas menjadi kurang optimal. Apabila tidak ditangani dengan tepat,&#13;
permasalahan tersebut dapat menunrunkan kualitas sistem pendukung keputusan&#13;
dibidang Kesehatan.&#13;
Penelitian ini bertujuan untuk menganalisis pengaruh berbagai metode&#13;
sampling dalam meningkatkan kinerja model klasifikasi diabetes. Metode yang&#13;
digunakan adalam Random Fores dan XGBoost dengan menggunakan beberapa&#13;
pendekatan penanganan ketidakseimbangan kelas, yaitu SMOTE, ROS,&#13;
SMOTENN, ADASYN, RUS, ClusterCentroids, Tomek Links, dan ENN. Evaluasi&#13;
kinerja model dilakukan menggunakan metrik akurasi dan F1-score guna menilai&#13;
keseimbangan performa dalam mengklasifikasikan kelas mayoritas dan minoritas.&#13;
Hasil penelitian menunjukan bahwa metode Tomek Links memberikan&#13;
peforma yang paling konsisten pada kedua model. Pada model XGBoost, metode&#13;
ini mampu meningkatkan nilai F1-score diabanding data asli, sedangkan pada&#13;
model Rndom Forest performanya relatif stabil dengan perbedaan yang tidaak&#13;
signifikan. Penelitian ini memberikan konstribusi dalam pemeilihan metode&#13;
sampling yang efektif untuk klasifikasi data medis. Hasil penelitian dapat&#13;
dimanfaatkan oleh peneliti, praktisi data, dan institusi Kesehatan sebagai&#13;
referensi dalam pengembangan system klasifikasi penyakit berbasis pembelajaran&#13;
mesin.</mods:abstract><mods:classification authority="lcc">000 Ilmu komputer, informasi dan pekerjaan umum</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">2026-03-02</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>Universitas AMIKOM Yogyakarta;Fakultas Ilmu Komputer</mods:publisher></mods:originInfo><mods:genre>Thesis</mods:genre></mets:xmlData></mets:mdWrap></mets:dmdSec><mets:amdSec ID="TMD_eprint_32116"><mets:rightsMD ID="rights_eprint_32116_mods"><mets:mdWrap MDTYPE="MODS"><mets:xmlData><mods:useAndReproduction>
