      "abstract": "Penyakit jantung merupakan penyebab utama kematian global, dengan\r\nproyeksi WHO menunjukkan sekitar 20,5 juta kematian pada 2025 dan akan\r\nmeningkat hingga 35,6 juta pada 2050 akibat faktor risiko seperti hipertensi, pola\r\nmakan buruk, dan kurang olahraga. Di Indonesia, prevalensi penyakit jantung terus\r\nmeningkat, dengan data BPJS Kesehatan mencatat beban biaya katastropik tertinggi\r\nmencapai puluhan triliun rupiah per tahun, serta tren naik dari 0,5% (2013) menjadi\r\n1,5% (2018) berdasarkan Riskesdas. Tantangan diagnosis dini dan analisis data\r\nmedis besar mendorong pemanfaatan machine learning untuk prediksi akurat.\r\nPenelitian ini membandingkan performa tiga algoritma machine learning\r\nLogistic Regression, Random Forest, dan XGBoost dalam klasifikasi penyakit\r\njantung menggunakan dataset publik dari Kaggle dengan 1048 baris. Proses\r\nmeliputi cleaning data, seleksi fitur dengan SelectKBest (menghapus cholesterol\r\nkarena skor rendah), standarisasi, splitting data (80:20 dengan stratify), pemodelan,\r\nserta optimalisasi hyperparameter menggunakan GridSearchCV.\r\nHasil menunjukkan bahwa Random Forest dan XGBoost mencapai nilai\r\nROC-AUC tertinggi 0.90 setelah tuning, dengan peningkatan signifikan\r\ndibandingkan tanpa tuning, sementara Logistic Regression berada di 0.84. Fitur\r\npaling berpengaruh adalah ST slope, chest pain type, dan exercise angina. Random\r\nForest direkomendasikan sebagai model terbaik karena keseimbangan akurasi,\r\nstabilitas, dan kemampuan diskriminasi. Penelitian ini memberikan kontribusi\r\nuntuk deteksi dini penyakit jantung berbasis data publik, dengan saran\r\npengembangan menggunakan dataset lokal Indonesia dan integrasi ke sistem\r\nkesehatan.",
