- Abstract
At PT. Krakatau Posco, the Plate Rolling section has three sectors namely the mill finishing sector, shearing line and finishing line. The study was conducted at the shearing line, aiming to determine the factors causing damage to the resulting steel plate products. The study was conducted using the Six Sigma method, as an effort to improve the quality produced, which consists of DMAIC (Define, Measure, Analyze, Improve, and Control). At the problem solving stage, the application of 5W + 1H (What, Who, Where, When, Why, How) is used. These six questions are questions that can help solve problems and generate ideas in improvement efforts. By following the steps in the Six Sigma method and the 5W + 1H implementation, it is known that the DPMO value is 6194 tons, with an σ value above an average of 4.03, while cutting defect is one of the company’s problems with the largest defect rate and efforts are needed minimizedefect rate of 7,272 tons, second with a total number of scratch defects of 5,748 tons and third marking defects of 5,595 tons within 12 months. To reduce the level of defective products (defects) in the production process, it is necessary to improve the factors affecting the quality of production including, human (employees), materials, machinery, methods and the environment.
