The largest defect is dominated by the ring shake defect type, FMEA analysis shows that the method factor has the largest RPN value so that corrective action needs to be taken in the use of wood protection by creating a new wood storage warehouse, applying additional protection, careful handling during the wood production process, and carry out regular monitoring.
