Abstract
Company engaged in manufacturing that produces door leaf. This company is a factory whose work is done semi-automatic that man has a role in sustainability of production process. A problem in the production process of the door where there is a defect which is the main cause factor is human (human error). This problem can be solved by performing human error analysis with SHERPA and HEART methods. Systematic Human Error Reduction and Prediction Approach (SHERPA) analyzed occurrence of human error by using a hierarchical task input basic level while Human Error Assessment and Reduction Technique (HEART) part the calculation reliability is defined as how much operator made a mistake in the task that should be done. From the research found the results obtained SHERPA methods work items that have a critical level that is 2.2 (too long), 8.2 ( too long), and 11.2 (the flat part of the door yet). Based on the research with HEART method obtained the total value of HEP is 0.4986 where the value is influenced by EPCs factor. Based on the data obtained then possible troubleshooting for item 2.2, 8.2, and 11.2 issues is by improving operator skill.
