Abstract

Metal Casting XYZ is engaged in manufacturing souvenirs and household appliances from aluminum. The production process begins with smelting raw materials to make the finished product. Based on the initial observations of the process of making the frying pan, it was found that the reject product was 3-5%, while the tolerance limit for the reject product in the company was 2%. One of the causes of product rejection is human error which causes quality deviations and has an impact on the quality of the foundry products. The purpose of this study was to identify the causes of errors in the casting wok operator. This study uses the Systematic Human Error Reduction Prediction and Approach (SHERPA) to identify errors that occur by knowing the cause and suggesting improvement strategies. Fault identification is carried out based on Hierarchical Task Analysis (HTA) task analysis with an error taxonomy to identify credible errors related to the casting process activity. Based on the results of the study found that 37 tasks of work activities are divided into 4 sub-tasks with error identification found in 10 work tasks. The ordinal probabilities found were 5 tasks for high level, 3 tasks for medium level, and 2 tasks for low level. Suggestions for improvement given to minimize or reduce the occurrence of errors are in the form of making Standard Operating Procedures (SOP) equate work implementation guidelines and making checklist forms as checking tools for operators in checking and preparing tools and materials needed in the production process.
