yang semakin mendapat perhatian, khususnya pada kalangan remaja. Penelitian ini&#13;
bertujuan untuk memprediksi kondisi kesehatan mental siswa menggunakan&#13;
pendekatan regresi berbasis machine learning dengan algoritma XGBoost. Untuk&#13;
meningkatkan performa prediksi, dilakukan optimasi  menggunakan tiga metode,&#13;
yaitu Genetic Algorithm , Particle Swarm Optimization , dan Bayesian&#13;
Optimization . Evaluasi performa model dilakukan menggunakan metrik Mean&#13;
Squared Error (MSE), Root Mean Squared Error (RMSE), Mean Absolute&#13;
Percentage Error (MAPE), dan koefisien determinasi (R²). Hasil eksperimen&#13;
menunjukkan bahwa model baseline menghasilkan nilai MSE sebesar 0,8893,&#13;
RMSE 0,9430, MAPE 23,31%, dan R² sebesar 0,3841. Setelah dilakukan optimasi, &#13;
seluruh metode menunjukkan peningkatan performa model. PSO menghasilkan &#13;
nilai MSE dan RMSE terendah serta nilai R² tertinggi sebesar 0,5135, GA&#13;
menghasilkan nilai MAPE terendah sebesar 21,89%, sedangkan BO menunjukkan&#13;
performa yang kompetitif dalam meminimalkan kesalahan prediksi secara relatif.&#13;
Hasil ini menunjukkan bahwa optimasi  secara signifikan meningkatkan performa&#13;
model prediksi kesehatan mental siswa, namun efektivitasnya bersifat kondisional&#13;
dan dipengaruhi oleh kesesuaian metode optimasi dengan karakteristik data&#13;
psikososial yang digunakan.</mods:abstract><mods:classification authority="lcc">000 Ilmu komputer, informasi dan pekerjaan umum</mods:classification><mods:classification authority="lcc">003 Sistem-sistem</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">2026-01-07</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>Universitas AMIKOM Yogyakarta;Pascasarjana Magister Informatika</mods:publisher></mods:originInfo><mods:genre>Thesis</mods:genre></mets:xmlData></mets:mdWrap></mets:dmdSec><mets:amdSec ID="TMD_eprint_31802"><mets:rightsMD ID="rights_eprint_31802_mods"><mets:mdWrap MDTYPE="MODS"><mets:xmlData><mods:useAndReproduction>
