Abstract

Errors during working recorded by PT X were believed by the company as one of the source operational failure and work accident. Based on accident report, there were noted that 53 accidents related with human failure as the cause. The preliminary survey result showed respondents mostly stated that accidents caused by unsafe action. This finding led to relation with cognitive activity of human. This research was aimed to identify human error during work which has potentiality becoming accident. The used method was part of Cognitive Reliability and Error Analysis Method (CREAM), a method for identifying error based on cognitive activity. First step was determining common performance condition (CPC) by questionnaire consisted of nine aspects which were adequacy of organisation, working condition, adequacy of man-machine interface and operational support, adequacy of procedure / plans, number of simultaneous goals, available time, time of day, adequacy of training and experience and crew collaboration quality. The next step was constructing hierarchical task and defining the error. Valuation of error was becoming the next step with making relation between cognitive activity ( coordinate, diagnose, communicate, execute, etc) and cognitive function consisted of observation, interpretation, planning and execution. The last step was determining the failure of cognitive function for each activity. From four cognitive function, based on analysis, the failure were dominated by observation and execution and the strategy should be implemented was tactical control. Keywords : work accident, human error, cognitive activity, cognitive function
