Abstract

The company CV. XYZ, located in Central Java, produces various types of animal feed according to the age of the consuming animals. However, there are quality issues with the pellet products they produce. Common problems include pellet color inconsistency, low density with ash content between 4-6% making the pellets prone to breaking, and pellet sizes not meeting industry standards, which should range between 0.3 to 0.5 cm. To reduce defects in animal feed production, the Six Sigma approach was applied to trace and identify the root causes and formulate improvement solutions. Data processed and Analyzed through control charts indicated that all values were within the upper and lower control limits, indicating that the process was statistically controlled and conformed to the standards set by the company. It was found that the average sigma value for Indonesian industrial companies is 2 to 3 sigma, while the sigma value at CV. XYZ reached 3.63. Although already above the industry average in Indonesia, CV. XYZ needs to continuously improve to meet the quality standards desired by consumers. Therefore, it is recommended to apply the 5W+1H method (What, Why, Where, When, Who, How) as a systematic approach to support continuous quality improvement.

Abstract

CV.XYZ is a business that produces golf gloves in Yogyakarta Special Region. In the production process, several wastes were identified, including defects of 24,746 units out of a total of 365,568 units. Defective products can trigger inappropriate processing waste, the rework process requires 176.1 seconds/pcs. Waste waiting and transportation were identified due to 24 transportation activities with a total time of 323.10 seconds and a distance of 161 meters. This study aims to identify the causes of waste and recommend improvements using the Lean Six Sigma method. It is known that the CV. XYZ sigma performance level is 3.62 sigma and Current VSM data shows VA activities of 46% (655.86 seconds), NVA 39% (556.57 seconds), NNVA 15% (219.94 seconds), and lead time 1,432.37 seconds. To prevent product defects and reduce inappropriate processing waste, an SOP was created for tailoring. Recommendations for improvement to minimize waste transportation and waiting are to rearrange the layout of the sewing, semi-finishing, and finishing areas. After the improvement, VA activity increased to 64% (655.86 seconds), NVA decreased to 14% (142.24 seconds), and NNVA increased to 22% (219.94 seconds).
