ANALISA PENYEBAB TINTA BERSERAKAN PADA PROSES PRODUKSI NOTEPAD MENGGUNAKAN FAULT TREE ANALYSIS (FTA) DAN FAILURE MODE AND EFFECT ANALYSIS (FMEA)

Abstract

ABSTRACT PT. X is one of growing printing company at Padang City. Company produces some printing product such as book, invitation, notepad etc. This research was focused on scattered ink defect that often occurred at notepad production process. That defect cannot be repair, so that become a reject product. The objectives of this research were identified root cause of scattered ink defect by used Fault Tree Analysis (FTA), analyzed potential cause of failure with Failure Mode and Effect Analysis (FMEA) method and proposed of improvement to minimize potential failure used 5W+1H. The result shows potential failure of scatterd ink were operator does not pay attention of water drains to rollers and machine was old. The RPN value for scatterd ink about 512. Final result proposed a work instruction and preventive maintenance to prevent scatterd ink occurred in production process.
