Abstract

Problems in the industry with the mass customization system are quite complex because of the frequent reconfiguration by the changes of production process systems according to customer orders, so quality assurance is demanded to be more accurate according to the number of different part types and the interruption of the information flow about quality with each reconfiguration of the system. This study aims to build a model of quality control systems that are capable of detecting product defects by quickly adjusting changes in production lines according to customer desires. The method used to detect product defects is Defect Tracking Matrix (DTM). DTM connects manufacturing techniques with direct quality defects. This allows finding the cause of quality defects quickly. The quality control model that was built was applied to the Plywood Industry in Probolinggo, PT Kutai Timber Indonesia (KTI) in the Particle Board Division. Product variations are based on density, glue type, thickness, size, and wood type. There are 12 stages of the process in producing particle boards before being sent to customers. Product defects that often occur are in the cut to size and sanding process so that the specific DTM module is carried out in its. There are 12 stages of the production process of particle boards before being sent to customers. Product defects that often occur are in the Cut to Size and Sanding process so that the specific DTM module is carried out in its. There are 18 techniques attributes (TAs) that represent the manufacturing process module and 16 quality defects (QDs) in the Ply Wood Industry with sample of particle board process. The procedure of DTM is usefull to detect defect faster than usually.
