Abstract

The application of MRP at PT. Lixil Aluminum Indonesia which is Best on Project requires data analysis for the past one year to determine the Forecast for the following year, Forecasting Weight Moving Average forecasting model, Forecasting Single Moving Average Method, Forecasting Single Exponential Smoothing. Use of forecasting by considering 2 methods namely LOL (Lot for Lot) and FOQ (Fix Order Qty). PT. Lixil Aluminum Indonesia can forecast every month using the Simple Moving Average method, because in this analysis a comparison has been made with other methods, namely the Weighted Moving Average and Single Exponential Smoothing methods and it is proven that the Simple Moving Average method is more efficient because it produces an error value (MAD), (MSE and MAPE) are the smallest: (MAD = 418), (MSE = 2300), (MAPE = 19%). And to make planning more efficient, use the Lot For Lot method because if the Fix Order Quantity costs are greater, the difference in costs is IDR 20,663,899.00.
