This forecasting uses a single exponential smoothing method which has one smoothing parameter that satis es a value between 0 and 1 obtained through trial and error. Then linear programming is used for determining an optimal smoothing parameter value. This method simply sets the forecast value of future period with a measure of forecasting error using MAE (Mean Absolute Error) and MAPE (Mean Absolute Percentage Error). This forecasting method is implemented in a case of predicting the sale price of bunch of palm at a company in Riau.enforecastingsingle exponential smoothing methodMAEMAPEstudent Paper Post Degree
