Utilization of technology in various service activities and loading and unloading facilities at the International Container Terminal in Surabaya (ICT) causes increased interaction between humans and machines, one of which is the Rubber Tyred Gantry (RTG) device operated by the operator. A large number of RTG equipment used has a very high potential for work accident hazards. The recapitulation of accident data for 2015-2021 shows that there have been 1,074 accidents. Several accidents at ICT is caused by an error from the operation of the equipment or human error factor. The purpose of this study was to analyze the human reliability assessment on the operation of the RTG using the Systematic Human Error Reduction and Prediction (SHERPA) and Human Error Assessment and Reduction Technique (HEART) methods, with primary data obtained through interviews with expert judgments. Based on the research that has been done, the probability value of the occurrence of human error in the operation of the RTG found the highest HEP value results, namely in subtasks 2.4 and 4.3 with a HEP value of 0.496 each and also with a total reliability value (Rm) in the operating process resulting in an Rm value < 0.5 which indicates the reliability of the operator is still low in carrying out the entire process. The recommendations given include a refreshment program and socialization related to work instructions to RTG operators.
