Abstract
Kematian merupakan peristiwa yang tidak dapat diperkirakan waktu kejadiannya sehingga dapat dialami oleh semua orang. Kematian dapat disebabkan oleh berbagai macam faktor, dalam penelitian ini diduga ada lima faktor yang mempengaruhi kematian seorang pekerja atau aparatur sipil negara (ASN). Penelitian ini bertujuan untuk mengetahui model survival yang terjadi pada kematian seorang pekerja aparatur sipil negara (ASN). Faktor-faktor yang diduga mempengaruhi kematian seorang pekerja akan dimodelkan dengan waktu ketahanan hidup (waktu survival), sehingga akan diketahui faktor-faktor mana saja yang berpengaruh secara signifikan terhadap waktu survival pekerja. Pada penelitian ini akan dilakukan pendekatan dengan metode bootstrap, yang merupakan pengambilan sampel secara random berdasarkan data asli sehingga akan didapatkan parameter-parameter yang signifikan dengan melakukan pengujian confidence interval. Berdasarkan analisis ini dengan memasukkan semua variabel, hasil Kaplan-Meier menunjukkan menurun sampai rentang waktu 40 tahun. Pengujian log-rank menunjukkan variabel jenis kelamin dan anak tidak ada perbedaan secara signifikan antara kurva survival disetiap kelompoknya. Berbeda dengan variabel golongan pekerja dan pasangan diketahui bahwa variabel tersebut memiliki perbedaan kurva survival antar kelompoknya. Pemodelan regresi cox proportional hazard menghasilkan variabel golongan 4 dan pasangan yang berpengaruh secara signifikan terhadap waktu survival pekerja.
