Abstract

The development of the industrial world from the manufacturing sector must always be carried out by each manufacturing company so that the products marketed are not dead in the market because they are less competitive than their competitors. This is what drives companies to always supervise and make improvements to improve the quality of the products produced. PT.XYZ is one of the manufacturing companies engaged in the national steel industry whose main activity is producing concrete reinforcement steel with the main raw material being hot billets. In carrying out its production, PT.XYZ is not uncommon to find the products that are rejected due to defects. This research was conducted to analyze the number of defective goods produced with the aim that the quality of the products obtained increases and the level of income obtained is more leverage using the Six Sigma method. Cause and effect diagrams (fishbone diagrams) and Pareto diagrams are also used in this study to determine the causes of existing problems and the scale of priority problems that must be solved first. Based on the calculation of the percentage of damage, it can be concluded that there are four cases of the highest defect products, namely: 63.93% non-standard length, 15.51% ear defects, 12.67% digestion, and 7.9% cracking. At the end of this study, the results show that the capability and sigma value of company performance in improving product quality amounted to 7916.2 DPMO with a sigma value of 3.916.

Abstract

Productivity and efficiency are two main things that can be used as benchmarks for success from the Delivery section of the SCM department. Productivity is the main point in assessing whether the Delivery system in the warehouse is feasible or has not reached its target. In the last few periods after carrying out a track record of the historical data of the shipment of goods. It was found that in one week there were frequent deliveries to the same user drop point location, meaning that this could lead to waste & waste from inefficient work. In connection with that, a new system is implemented, the scheduling system, which is a delivery system for delivering material with a predetermined schedule every week. This research is intended to produce a productivity analysis that shows whether this new scheduling system can increase productivity and delivery efficiency when compared to an aging system or vice versa by using a productivity analysis methodology and efficiency level benchmarking using data envelopment analysis (DEA). The results of the aging system productivity analysis have a better value, namely 34%, while the scheduling system is 26%, but scheduling has a shorter distance so it can make savings. Meanwhile, in comparison to efficiency using benchmark factors, it is found that the aging system is more efficient with an optimum value of 1, and scheduling of 0.9855535 is considered inefficient.

Abstract

Number Box Toys are children’s toys for children aged 1 to 4 years, designed to help children develop their cognitive and motor skills and learn about different number shapes and colors, including the number 0 to 9. The aim of developing this educational game prototype is to provide a visual image of the product and determine the production cost of the Number Box Toys product which is manufactured using 3D printing machine. Before making a prototype, Number Box Toys product design was created in 2D and 3D using Solidwork software, and then a Bill of Materials (BOM) and Operation Process Chart (OPC) were created. When producing the Number Box Toys prototype, simulation software was used using the Creality Slicer application to show the total time required to produce a Number Box Toys product, which was approximately 1803,78 minutes or 30,063 hours. The total time required to complete the entire operation process chart of Number Box Toys is 1822,78 minutes or about 30,38 hours, with details of 57 operation processes and 18 inspection processes. The results of calculating the production cost of the Number Box Toys educational game based on the total time required, material prices and labor costs resulted in a production cost value of Rp 404.690,89 and the selling price is Rp 465.383,03 with a profit of 15% of the cost price is Rp 60.702,13. There is a significant price difference compared to similar products sold on the market because Number Box Toys’ product prototype is made using 3D printing process, which requires a lot of time to make each part but has a size or shape that can be customized to suit the consumer.
