Coal transportation activities in Kalimantan, Indonesia, contribute to the largest number of work accidents every year. This is because a lot of mobile mining equipment is involved in this activity, especially dump trucks which are the main means of transporting coal. The main cause of incidents is human error made by workers, for this reason it is necessary to investigate human error to be able to prevent potential work accidents. The aim of this research is first to identify and analyze possible errors that occur in each job classification in coal transportation activities using the SHERPA method. Second, carry out risk quantification to determine the risk ranking of identified errors to obtain critical errors, by assessing the severity level, frequency of occurrence, and error detection capabilities using the FMEA method. Third, look at the impact of identified critical errors on potential accidents through a SURVEY, by looking at the perspectives of 380 coal truck operators. The research results identified 15 human errors that had the potential to cause accidents, with the most common error mode distribution being errors resulting from actions that were not in accordance with applicable standard operating procedures. Then answering the second objective, three critical errors were obtained from the results of the risk ranking, namely driving while fatigued, the maintenance schedule for the coal truck not being managed properly, and not following the speed limit instructions when crossing the haul road. Furthermore, in the third stage of the study, namely looking at the influence of errors on the potential for work accidents from the perspective of haul truck operators, it was found that based on the three critical errors, the one with the most significant influence was not following speed limit instructions while crossing haul road. This shows that the identified human errors contribute to potential work accidents. For this reason, control measures need to be taken by increasing supervision, evaluating facility improvements, and more intensive safety campaigns.
