Abstract

Control chart is one of tools for quality control of production. x ̅ control chart is one of tool that can be used to control the quality of production for variable data such as weight of product. However, there is one of weakness in the method of x ̅ control chart, which is sensitivless in detecting small shift of the mean process. Exponentially Weighted Moving Average (EWMA) control chart is one of the quality control tool that can be solution for the weakness of x ̅ control chart. EWMA control chart has a weight smoothing parameter (λ) which makes EWMA control chart more sensitive in detecting small shifts the process mean. Each production data will be weighted smoothing and past production data will affected by present production data. EWMA control chart will be use to make a control chart by weight of cigarette data in Brak Megawon III PT Djarum Kudus. In this study, will be established to assist in the GUI Matlab computational EWMA methods chart controller to control the quality of production at PT Djarum Kudus. In this study showed that the most optimum weight refiner which is at a value of 0.6. Key word : EWMA, Smoothing weight (λ), GUI, Weight of cigarette
