      "abstract": "Penyakit diabetes melitus merupakan gangguan metabolisme kronis yang\r\nmemerlukan deteksi dini. Pemanfaatan machine learning pada data rekam medis\r\nsangat berpotensi untuk membantu diagnosis, namun sering terkendala oleh\r\nketidakseimbangan kelas (imbalanced data) yang memicu bias pada prediksi model.\r\nPenelitian ini bertujuan membandingkan performa algoritma klasifikasi ensemble\r\ntree (XGBoost, LightGBM, dan CatBoost) serta menguji efektivitas Synthetic\r\nMinority Over-sampling Technique (SMOTE) dalam mengatasi masalah\r\nketidakseimbangan data tersebut. \r\nEksperimen menggunakan Pima Indians Diabetes Dataset dengan\r\nmenerapkan tahapan prapemrosesan seperti imputasi missing value, pembagian\r\ndata latih dan uji (90:10), serta penerapan SMOTE secara eksklusif pada data latih.\r\nModel dioptimalkan melalui hyperparameter tuning dan dievaluasi menggunakan\r\nmetrik accuracy, precision, recall, F1-score, serta ROC-AUC.  \r\nHasil penelitian menunjukkan bahwa SMOTE efektif mengatasi bias\r\nprediksi terhadap kelas mayoritas (pasien sehat). Berdasarkan komparasi, algoritma\r\nXGBoost memberikan performa paling superior dan seimbang dengan capaian\r\naccuracy 85,71%, precision 75,00%, recall 88,88%, F1-Score 81,35%, dan ROCAUC\r\n87,85%.\r\nSecara\r\nkeseluruhan,\r\nXGBoost\r\ndirekomendasikan\r\nsebagai\r\narsitektur\r\n\r\nterbaik\r\nuntuk\r\npengembangan\r\nsistem\r\ndiagnosis\r\ndini\r\nrisiko\r\ndiabetes\r\nyang\r\nandal\r\nsecara\r\n\r\nklinis",
