| dc.description.abstract | PT. Sehati Tortilla is a culinary industry enterprise specializing in tortilla
production. PT. Sehati Tortilla serves as a key supplier of tortilla skins in Medan
city. During the production process, PT. Sehati Tortilla encounters challenges in
quality control, specifically the continuous occurrence of defective products.
Common defects observed during production include tears, uneven spots,
inconsistent diameter, and uneven thickness. The Six Sigma method is employed to
address these issues at PT. Sehati Tortilla. This systematic approach comprises
the Define-Measure-Analyze-Improve-Control (DMAIC) stages. DMAIC is a
structured Six Sigma methodology aimed at enhancing business processes by
identifying problems, measuring current performance, analyzing root causes,
improving processes, and controlling to sustain improvements achieved. Based on
data collection and analysis, the highest failure sigma level obtained is 3.99,
indicating that the company has not fully optimized quality control practices. This
research explores the implementation of DMAIC in the context of defect product
improvement, highlighting specific steps taken to enhance product quality and
overall process efficiency. Consequently, a proposal for improvement is
formulated, focusing on establishing clear standards for storage, raw material
specifications, and other relevant areas. | en_US |
