Abstract

Float is a company that manufactures floats using Styrofoam raw materials which have defects in forming the Styrofoam pattern and cutting the float cloth. Fromthe results of data for 6 months, ZNA produced 168 units of buoys with 11 units of defective buoys and 159 units of safe buoys. The problem obtained is the defect of 11 defective product buoys so that the percentage of defective products is 6.91%, this makes the quality of the production process not good. In this research the method used is the fishbone diagram and the Fault Tree Analysis (FTA) stage or failure analysis tree. A fishbone diagram or fishbone diagram is a method for analyzing the causes of a problem or condition. Often this diagram isalso called a cause-and-effect diagram or cause effect diagram. Meanwhile, Fault Tree Analysis (FTA) or failure analysis tree is a technique used to identify risks that contribute to failure. This method is carried out with a top down approach, starting with the assumption of failure or loss from the top event or main event then detailing the causes of an operation down to a root cause. Based on the results of processing using the Fault Tree Analysis method due tohuman (employee) and material factors. The human factor is caused because the main thing is irregular break times and make-to-order production. While the material factor is caused because the main thing is the pattern that is made does not match while theamount of cloth to make the pattern is limited.
