Abstract

The dynamic competitiveness requires White Cracker MSMEs in Kediri to evaluate their Net Present Value, Internal Rate of Return, Payback Period, and Profitability Index. The assessment carried out at this level is to produce value standardization for the progress of these MSMEs. The findings show that the NPV exceeds Rp. 143,316,000, the IRR is above 50%, the PBP is less than 7 months 9 days, and the PI is greater than 1.00. This indicates that the white cracker MSME business has strong development potential and offers profitable returns for the owners. The profit potential is good for the white cracker MSME business. However, the quality of products with good taste and in accordance with consumer needs is important to build customer loyalty. Strength Strategy – Opportunity to use Unique Products-Digital innovation marketing components, Kediri original product market potential-Products that are attractive to tourists visiting Kediri and the latest taste tests for consumers-Different taste innovations from 1 product. Strict product development and quality control are carried out in order to always be of high quality and meet consumer expectations.

Abstract

This study aims to analyze the types and root causes of plywood product defects in the production process at PT. SXX using the Six Sigma approach through DMAIC stages (Define, Measure, Analyze, Improve, Control). The main issue identified is the high defect rate of 2.9%, or 1,971 defective units out of a total production of 67,705 sheets in 2024. The critical defect types include bubbles, delamination, and core holes. This quantitative research employs tools such as Pareto diagrams, fishbone diagrams, and 5 Whys analysis to trace the root causes of defects. The results indicate that the dominant factors are improperly dried raw materials, unstable machinery, uneven glue distribution, and a lack of supervision and SOP understanding among operators. Improvements were made through the provision of MC meters, glue spreader calibration, operator training, and improvement of veneer storage environments. Post-improvement, the defect rate is targeted to drop below 2.9%. This study also supports the implementation of Green Supply Chain Management (GSCM) by promoting energy efficiency and reducing production waste, thereby contributing to the improvement of product quality and competitiveness.
