Abstract

The development of industry in this current era is progressing rapidly, marked by increasing competition among companies. The method used is the Six Sigma method with the DMAIC approach (Define, Measure, Analyze, Improve, and Control). With this method, data obtained includes a total number of both good and defective products, which are then classified into several predefined defect categories by the company. Based on the data analysis results from July 2022 to December 2022, PT ABC  identified four types of defects in packaging products. These defects include sticking with a defect percentage of 54%, cracking at 27%, coloring at 18%, and scratching at 2%. Improvement efforts can be made through training, guidance, and supervision of operators to enhance product quality. Additionally, strict supervision of raw materials in packaging production is necessary to ensure their quality is maintained. Furthermore, the machine setting process also requires supervision and guidance, with the implementation of clear Standard Operating Procedures (SOP) for each product.

Abstract

PT. A is a company engaged in the manufacturing industry with products produced in the form of (dies, jigs, and parts manufacturing). During the activity, the CNC milling machine Milltex Vex 580b experienced engine damage which resulted in the machine working unproductively and affecting the level of effectiveness of the CNC milling machine Milltex Vex 580b. Overall Equipment Effectiveness (OEE) is a method consisting of availability level, quality level, and performance level as a measurement of optimal machine performance tool productivity to maintain the effectiveness of a machine. To eliminate losses using Six Big Losses which are six big losses that can affect the level of machine effectiveness, the average OEE result is 69% where this result is still below world-class standards. This is due to losses caused by a reduction in loss speed of 42%. By analyzing the fishbone diagram (consequences) of this method, it can be concluded that the cause of the low effectiveness value in machine performance is due to the level of availability which is influenced by the reduction in loss speed.           Keywords: Effectiveness, Overall Equipment Effectiveness, Six Big Losses

Abstract

Competition in the business world is getting tougher, encouraging companies to improve and develop the quality of their production, the quality of the goods or services produced will affect the competition of a company. Making the production process more effective is something that companies must do to increase production results and can affect company costs. PT.GCE is a manufacturing company operating in the Sheet Metal sector and the production process takes place on a job order basis. In the production process, various deviations and obstacles often occur which result in products experiencing non-conformities, both in product form and processing time. The Six Sigma method is a business strategy that is considered capable of improving and maintaining a company's operational excellence. The results of calculations carried out using the DMAIC method in the Part End Plate production process obtained data on 0.048 defects in the non-conforming product category and 0.084 defects in untidy products, so it can be concluded that defects in Part End Plate products are below 3.4 defects out of a million opportunities. From the calculation results, it was found that the factors causing defects in the Part End Plate production process could be caused by several factors experienced, including machine and labor factors. It is necessary to propose improvements that can be made in an effort to reduce the level of product defects in Part End Plate products so that defects no longer occur in the product.
