Tea is a world-famous beverage made from the tea plant (Camellia sinensis L.) various types of as black, green, oolong, and white tea. The purpose of this study was to analyze the daily quality consistency of black tea (including moisture content, steeping quality, and yield) at PT. Mitra Kerinci using the Individual Moving Range (I-MR) chart method and the Failure Mode and Effect Analysis (FMEA) method. These methods were applied to identify factors and potential causes of variations in the quality of black tea based on critical points and critical conditions. The result indicated that the water content value was in statistical control, while the steeping quality value and the yield were out of statistical control. The main factor causing the variation in the quality of black tea with the highest RPN value (560) was the damage that occur to the machine. The proposed improvements that can be suggested are to carry out regular checks on each machine and immeadiately repair the machine when needed.
