Pengambilan Keputusan Moda Transportasi Tambang Bijih Bauksit Berdasarkan Analisis Risiko

Abstract

Mine transportation refers to the activity of delivering materials, goods or people from one mine site to another in the context of the mining industry. PT ANTAM Tbk feels that the truck transportation mode is still not the optimal mine transportation in the implementation of the bauxite ore transportation project, especially in terms of risk, so a risk assessment and risk comparison with other alternative mine transportation is needed. In this study, heavy train is used as an alternative choice of other mine transportation modes in the implementation of the bauxite ore transportation project. The purpose of this study is to determine the best transportation mode among truck and heavy train transportation modes based on risk analysis. This research was conducted using the Failure Mode and Effects Analysis (FMEA) method used to identify risks and appropriate mitigation measures on truck and heavy train transportation modes and the Analytic Hierarchy Process (AHP) used for the selection of the selected transportation mode. The results of the calculation of all levels using expert choice 11 software obtained the results of the final calculation of the selection of the selected mode of transportation obtained the highest priority vector ranking, namely the heavy train alternative with a percentage of 68.3%. The Risk of Bauxite Delivery Process is the type of risk with the highest rank with a percentage of 55.3%, meaning that the bauxite delivery process is the biggest consideration for PT ANTAM Tbx.
