Abstract

Laboratories that are quite productive in designing and developing products that have been made and marketed on an internal scale include floor cleaning liquid, hand washing liquid and dish washing liquid. It's just that most of the products are produced based on customer orders or make to order. So when there are orders in large quantities, customers have to wait a little, between two and three days, because cleaning fluid products have to be produced first. The estimated need for Handsoap products is 49 liters, floor cleaning fluid is around 75 liters, dishwashing liquid is estimated at 81 liters by testing the forecasting method, the forecasting method that should be used as a basis for decision making is used to estimate the need for Handsoap products using the 4-month moving average method. The forecasting method for estimating the need for floor cleaning fluid products is the exponential smoothing method ? = 0.2. And the forecasting method for estimating the need for dishwashing liquid products is the exponential smoothing method ? = 0.2 which has a relatively smaller error value compared to other models.

Abstract

CV. Sinar Kencana Abadi is a service company engaged in the field of retreading used tires that are processed into new tires. In its production process, the company still has a challenge in the form of defects in tire products caused by internal and external factors of the company, so that the products produced do not meet the quality standards set by the company. The purpose of this study is to identify the cause of defects in retreaded tires, to analyze whether product defects are still within control limits and to provide suggestions for improvement to improve the quality of retreaded tire products at CV. Sinar Kencana Abadi. This study uses a statistical quality control (SQC) method and applies seven tools with the following research results, the factors that cause defects are Inflated Tires and Unripe Tires in retreaded tire products. From the two defects, it is known that the total defect in Inflated Tires is 75pcs and the total defect in Unripe Tires is 71pcs. This is due to five factors such as humans, machines, methods, raw materials, and the environment which are the root of the problem. And then the company makes improvements to optimize its production process, including providing training to employees, carrying out routine machine maintenance, and selecting good raw materials as well as conducting direct supervision of defective products produced.
