Penggunaan Peta Kontrol Proporsi Untuk Mengukur Cacat Pada Kemasan di PT. X

Abstract

Efficiency is one of the important goals of all companies. Company X is trying to reduce the number of defective packaging that occurs in parts of the packaging process. In general, defective products can cause time losses, cost losses and potential loss of customers. Time losses occur because companies have to repair defective products and lose time that could have been used for production. Cost losses occur because the company has to lose damaged packaging and has to pay more labor. To determine quality improvement priorities, company X must know which packaging processes produce the most defective products. The way to find out this priority is by measuring quality. Quality measurements were carried out on three types of machines. Namely small size packaging machines, medium size packaging machines and large size packaging machines. This measurement uses one part of statistical process control, namely the p-chart or proportion control map. Measurements using a p-chart make medium-sized packaging machines a priority for improvement. Because it produces the highest standard deviation value which can be interpreted as having high process variation. Apart from that, it also produces the highest proportion of defects and high production time losses.
