Abstract

Wheat consumption in Indonesia is predicted to increase by 4% in 2030. Six Sigma is a complex methodology for improving production quality. Popular Yellow Tofu in Kediri has high demand, but is hampered by production capacity and production failure rates. This study increases the competitiveness of the Stonow Kediri Yellow Tofu Industry through DMAIC with a focus on sustainable quality control. An innovative approach is used to review product defects by interviewing consumers directly. Production control construction through 6M with a focus on improving worker skills, instrument calibration, tested recipes, standard procedures, data recording, and maintenance scheduling. Focus on measurable actions and targets to reduce yellow tofu product defects. This study increases the competitiveness of Stonow Kediri yellow tofu with DMAIC with optimal soybean control (histidine, 7S β- conglycinin, B1aB1bB2B3B4, multi strain fungus (Lactiplantibacillus plantarum, Meyerozyma guilliermondii) and Neurospora for taste, texture and sustainable quality control with an increase in average sigma level from 2.03 to 2.31, namely 13.8%. Significant reduction in the number of product defects from 43.48% from a capacity of 302,417 DPMO to 170,822 DPMO. The application of DMAIC in the Stonow Kediri yellow tofu industry succeeded in improving product quality and reducing the number of significant product defects. This shows that DMAIC can be an effective strategy to increase industrial competitiveness.
