Abstract: Dairy products are prone to quality problems, including contamination by bacteria, microbes, and other harmful elements. Bumiku Hijau is a producer of goat milk powder with various flavors in Yogyakarta. This study aimed to determine the quality control process and the identification of the factors causing failure at the re-weighing stage of the final product of goat milk powder at Bumiku Hijau Yogyakarta. Data analysis used statistical quality control methods, which are the X-bar and R control chart to analyze the quality control of the final process of re-weighing goat milk powder. The causal diagram is used to identify the factors that cause the failure at the re-weighing step of the final product of goat milk powder. The results of the X-bar and R control chart analysis in the final product re-weighing process show that the overall final process of goat milk powder production is under statistical control. Identification of the factors that cause failure in the final process of goat milk powder production at Bumiku Hijau is the weight variability of the final product, where the variability of the weight of the final product is caused by human factors (employees), and machines (weighing the final product).
