Abstract
Cement is one of the industrial products that has a quality control process. Major component that consists of SiO2, Al2O3, Fe2O3, CaO, MgO and SO3 as basic component in cement product. This research explains about quality control of major component of cement by using MEWMAcontrol chart. The way to measure the performance of the control chart is used ARL as the average run observation to find the first out of control data. ParameterARL0 is the average run observation of in control data. In this research, it is assumed the data was in control. The optimization of ARL0 by weighted parameter of MEWMA control chart for λ=1, that is equal to Hotteling T2 chart. Optimal value of the weight parameter is determined by using the bisection method for then the variables did not show the outlier data. Finally, this research shows that cement production process is in control.
