Abstract

The development of the automotive world is currently growing rapidly, in achieving the company's goals to produce the quality of products that are in accordance with the customer's expectations. Companies must be able to create products with good quality, so that companies are able to compete in the market and can develop their business. There are many methods that discuss quality with their own characteristics. This study aims to analyze the implementation of production quality spare production of four-wheeled vehicles, especially the component number 5761 at PT Adyawinsa Stamping Industrials. The method applied in this study was the Statistical Quality Control (SQC) method. A quality control analysis was carried out using ventral statistical tools in the form of checking sheet, histogram, control chart, pareto chart, causal diagrams due to, recording the diagram, and stratification. The results of this study indicate that the product quality at PT Adyawinsa Stamping Industriales is still found in product disability. Main factors that influence product disability include due to human factors, machines, methods, materials, and environment.

Abstract

Sanggar Peni in Krebet Hamlet produces various wooden batik crafts such as key chains, wooden spoons and forks, masks, statues, mirror frames, and other souvenirs. However, there are production layout issues that cause time wastage and lower efficiency. One example is the distance between production processes, such as from cutting to engraving which takes 86,520 seconds with a distance of 41 meters, and from engraving to sanding which takes 23,312 seconds with the same distance. Research using lean manufacturing methods, Current Value Stream Mapping (CVSM), Block Plan, and OMH revealed the time required at various stages of production. The cutting process required a total of 391.25 seconds (320 seconds for operation and 71.25 seconds for transportation), engraving 2,018.38 seconds (2,000 seconds for operation and 18.38 seconds for transportation), and sanding 763 seconds (752 seconds for operation and 10.83 seconds for transportation). The total material handling cost reaches Rp16,214 per day. Based on Block Plan analysis, the highest R-Score value of 0.95 indicates optimal efficiency in the arrangement of production facilities, which is expected to reduce time wastage and increase productivity on demand.
