Human Reliability Assessment dengan Metode Human Error Assessment and Reduction Technique pada Operator Stasiun Shroud PT. X

Abstract

Human realibility is a big tricky problem. Human failure rates depend on three main factors, namely
intrinsic, work environment, and stress. PT. X is a supplier for PT. LG Indonesia manufacturing products
made from plastics. Human Realibility Assesment is conducted using HEART methods (Human Error
Assessment and Reduction Technique). In the first phase, task analysis on operators’ activities is done using
Hierarchical Task Analysis (HTA). The largest Human Error Probability was found when Operator No. 1
did not insert the flash side carefully. The value of this probability is 0.53424. This factor is concluded as the
main cause to shroud defectives, which results in customer penalyzing the company.
