Pengendalian Kualitas dalam Upaya Menurunkan Produk Cacat dengan Metode PDCA (Studi Kasus di PT. XYZ)

Abstract

PT. XYZ is a company engaged in the packaging printing industry. In the production process, defective products are quite natural, but every company has a tolerance limit or maximum limit for defective products as their reference in order to know whether the company's production process and quality are good or not. The company itself has a maximum percentage target for defective products, which is 1.5% of one week's production. In reality on the ground, the percentage of defective products exceeds the tolerance limit. From the background of these problems the company needs quality control which is useful for reducing product defects in production so as to achieve quality targets according to company expectations. Quality control activities are carried out using the PDCA method to find out the constraints that cause defective products and can make improvements to the problem of the defective product. Using the PDCA method requires analysis, so tools such as pareto, fishbone, and 5Why diagrams are needed to find out the root cause of the problem. After applying the PDCA method 2 times, the percentage of defective products decreased from 2.89% to 0.43%. This study also has the potential to save costs from activities carried out such as replacing the vacuum pad which has a potential cost savings of Rp. 6,480,000 per year and the cam follower replacement has a potential cost savings of Rp. 1,320,000 per year.
