Once tested , flour based planning application purchase price forecasting can predict the price and needs tapioca flour with Triple Exponential Smoothing method at UD . Rohmat Jaya and Determine the allocation of the amount of starch needs in the future . Based on forecasting system test and evaluation period at 20 Red Bear flour application has an error value of 5 % error
