Abstract

Product packaging is one of the important elements in the distribution or delivery of products to consumers. The packaging process starting from the machine, the materials used for packaging to the human resource factor must be considered and controlled properly so that the risk of possible product defects is small. The consumer pack department, PT Sinar Alam Permai is able to produce 25,000 pcs of co fortune 1 liter oil products every day which are ready to be distributed to consumers. Although the packaging process has been carried out with automatic machines and has obtained a quality management certificate, there are still many products that do not comply with company standards or commonly referred to as defective products. From the data obtained, the number of defective products per day can reach ± 700 pcs or about 2.8% of the production capacity per day. This research uses the statistical process control method as well as the tools of check sheet, C-chart, pareto diagram and ishikawa diagram to help quality control to reduce the number of defective products of co fortune 1 liter oil. Before the improvement, the average number of defective products was 690 pcs per day and after the implementation of the improvement, the average number of defective products was 472 pcs per day.
