Abstract: Abstract PT EX Batam is a manufacturing enterprise situated in Batam, Riau Islands, Indonesia. It specializes in the production of electronic components, including the Series B31. The quality control implementation conducted is inadequate as there are still numerous defective goods identified during the production process. The Series B31 production, in particular, needs further analysis as it has reached the defect tolerance limit. The objective of this study is to categorize the prevalent production defects, ascertain the underlying reasons of defective goods during the manufacturing process, and propose suitable recommendations for improvement. The research suggests utilizing Fault Tree Analysis (FTA) and Failure Modes and Effects Analysis (FMEA) as quality control methodologies. This study commences by gathering defect data from the company, which is subsequently analyzed to find the underlying causes of defects. Fault tree mapping is employed to uncover failure modes, enabling the determination of the highest Risk Priority Number value. This number is then used to establish the priority of defects that require immediate repair. The analysis of the sources of defects in this study reveals that they are mostly attributed to human, machine, and material factors. Consequently, it is necessary to propose improvements in employee training, enhance machine facilities, and optimize material handling. The recommended enhancements in this study are anticipated to assist enterprises in decreasing the occurrence of defect goods in alignment with company standards by a maximum of 1%, thereby contributing to the advancement of research in the manufacturing industry.
