Abstract
PT Temprina Media Grafika Gresik is one of the major printing companies in Indonesia that supports the Jawa Pos Group in the field of print media production. The products produced by PT Temprina Media Grafika Gresik are storybooks made of paper. The production process is supported by Web Rotary Offset Printing, Sheetfed Printing, and Finishing technology which function to produce products with high quality standards. However, in the production process of PT Temprina Media Grafika there are still several problems that have an impact on product defects. The purpose of this study is to determine the quality of storybook products and provide recommendations for improvements to improve the quality of storybook products at PT Temprina Media Grafika Gresik. The methods used in this study are Statistical Quality Control (SQC) and Fuzzy Failure Mode and Effect Analysis (F-FMEA). The tools used in the Statistical Quality Control (SQC) method are histograms, Pareto diagrams, process diagrams, scatter diagrams, control charts, and fishbone diagrams. While Fuzzy Failure Mode and Effect Analysis (F-FMEA) provides improvement suggestions based on the results of the fishbone diagram analysis. Based on the results of Statistical Quality Control (SQC), the most dominant defects were dirty paper appearance at 21.3%, followed by inappropriate color at 17.9%, inappropriate folds at 17.8%, varnish cracks at 15.4%, floy at 15.3%, and staple rejects at 12.3%. Meanwhile, based on the results of Fuzzy Failure Mode and Effect Analysis (F-FMEA), the Fuzzy Risk Priority Number value was obtained from five causal factors (cause of failure) with the first FRPN score, namely inappropriate folds at 3.42 with the cause of unstable temperature and humidity in the production room. Second, staple rejects at 2.62 with the cause of the operator not monitoring the sewing results regularly. Third, inappropriate color at 2.56 with the cause of the operator not carefully checking the color quality periodically. Fourth, varnish cracks at 2.29 with the cause of the varnish quality not according to specifications. Fifth, dirty paper appearance at 2.24 with the cause of the machine cleaning procedure not being applied consistently. Sixth, the floy was 2.08, caused by the paper having an inappropriate grammage and brittle fibers. Suggested improvements that the company can make include improving supervision, providing worker training, and identifying and inspecting raw materials before production to improve product quality and approach zero defects. Keywords: Fairy Tale Books, Fuzzy Failure Mode and Effect Analysis, Quality, Statistical Quality Control
