Abstract

Quality control of a product within a company is a demand to fulfill and achieve product quality in accordance with existing standards. With the quality control,, a problem or defect in the product produced can be seen. Research conducted in a company that operates in the electricity sector by producing products in the form of ceramic insulators. There are 4 types of defects produced, namely broken defects on the neck of the product, broken defects on the body of the product, broken defects on the legs of the product, and porous defects. The research was carried out using the Six Sigma method with the DMAIC stages, followed by an FMEA assessment table to find out the causes of defects from any defects that occurred, then find out solutions or corrective actions, and also an RPN assessment to provide priority information on which failures need to be reduced. After data processing, the Cp value was 0.7467, and the Cpk was 0.6477. Then, we obtained a DPMO value is 13.250, so the Sigma level obtained for the last 6 months was 3.72.
