The logistics division of PT XYZ faces potentially significant operational and financial losses due to defects in empty boxes used for product transportation. This research aimed to analyze the causes of these defects and propose improvement strategies to minimize them. Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA) were employed to identify potential failures and develop mitigation strategies. The study identified that the highest Risk Priority Numbers (RPN) were associated with defects in corrugate and pocket kanban, primarily caused by insufficient operator training and operator negligence, respectively. Continuous training for forklift drivers and the adoption of Radio Frequency Identification (RFID) technology were recommended to reduce these defects. These improvements are expected to increase operational efficiency and profitability at PT XYZ, potentially saving the company up to approximately Rp 144,841,264 annually.The logistics division of PT XYZ faces potentially significant operational and financial losses due to defects in empty boxes used for product transportation.
