Abstract

Penyakit paru-paru merupakan salah satu penyebab kematian yang dipengaruhi oleh berbagai faktor klinis pasien. Penelitian ini bertujuan untuk menentukan faktor-faktor yang memengaruhi risiko kematian pasien penyakit paru-paru menggunakan model Cox Proportional Hazard dan Random Survival Forest, serta membandingkan hasil kedua metode tersebut. Data yang digunakan merupakan data pasien penyakit paru-paru di Rumah Sakit Pertamina Balikpapan periode tahun 2024-2025 sebanyak 907 pasien dengan 98 kejadian kematian dan 809 data tersensor. Hasil analisis Cox Proportional Hazard menunjukkan bahwa variabel indeks massa tubuh dan diastolik berpengaruh signifikan terhadap risiko kematian pasien. Model akhir memenuhi asumsi proportional hazard setelah dilakukan penyesuaian menggunakan stratifikasi. Pada model Random Survival Forest, variabel yang memiliki kontribusi terbesar berdasarkan nilai Variable Importance (VIMP) adalah riwayat komorbid, indeks massa tubuh, dan saturasi oksigen. Hasil evaluasi menunjukkan bahwa model Cox Proportional Hazard memiliki performa yang lebih baik dibandingkan Random Survival Forest berdasarkan nilai C-index. Berdasarkan hasil penelitian, kedua metode secara konsisten menunjukkan bahwa indeks massa tubuh merupakan variabel penting dalam analisis survival pasien penyakit paru-paru. Kata kunci : analisis survival, Cox Proportional Hazard, Random Survival Forest, penyakit paru-paru.
