[Penelitian ini membahas mengenai komponen biaya Infrastructure Maintenance and Operations (IMO) pada perkeretaapian di Indonesia yang dikomparasikan dengan negara pembanding. Komparasi komponen digunakan untuk memberikan alternatif biaya perawatan dan pengoperasian prasarana kereta api. Dari komparasi komponen kemudian dilakukan prediksi biaya IMO di masa depan dengan costindex dan prediksi biaya IMO jika terdapat renewal. Setelah melakukankomparasi komponen kemudian diperoleh alternatif biaya IMO dan perhitungan untuk melakukan forecast biaya IMO di masa yang akan datang.;This study discusses the components of the cost of Infrastructure Maintenance and Operations (IMO) on the railways in Indonesia dikomparasikan comparator countries. Comparison of the components used to provide alternative maintenance and operating costs of railway infrastructure. From the comparison component is then done IMO predictions of future costs with cost index and prediction IMO ifthere is a renewal fee. After doing a comparative component is then obtained by an alternative calculation for the cost of IMO and IMO to forecast costs in the future.;This study discusses the components of the cost of Infrastructure Maintenance and Operations (IMO) on the railways in Indonesia dikomparasikan comparator countries.
