Analisis Penyebab Cacat Produk Furniture Dengan Menggunakan Metode Failure Mode and Effect Analysis (Fmea) Dan Fault Tree Analysis (Fta) (Studi Kasus Pada PT. Ebako Nusantara)

Analysis Cause Defect Products Furniture By Using The Method Failure Mode And Effect Analysis (FMEA) And Fault Tree Analysis (FTA) (Case Study In PT. Ebako Nusantara). PT. Ebako Nusantara is a company engaged in the field of furniture. The resulting products including chairs, tables, cabinets, and a crib. Production system does is make to order. High rates of defects in production processes that achieve 34.86% of the number of parts that are produced become large problems due to having to reworked products that do not fit the more impact on the length of time the process. According to the problems, the quality control is necessary in order to reduce amount of failed products. Efforts are being made to control the failed product is by using the method of Failure Mode and Effect Analysis (FMEA) and the method of Fault Tree Analysis (FTA) to identify and analyse the failure happened. The purpose of the use of FMEA is to determine where the failure modes that have the highest RPN value by multiplying the severity, occurrence, and detection.. Then the failure modes with RPN values above 100 be come as a top-level event on the diagram FTA. The FTA method is used to find out the root cause of failures that have occurred. At PT. Ebako Nusantara is the failure mode of the RPNnya value above 100 there are two namely bubble with a value of 150 and the size does not correspond with a value of 120. The cause of the failure is happening differenciated into two failures that are caused by the operator and failure due to the machine
