This research aims to study and compare the forecasting methods of forecasting methodologies 4 x smoothing methods, fall-simple (Simple Exponential Smoothing Method: SES)X smoothing methods, fall ladap label (Double Exponential Smoothing Method: DES) How decomposition (Decomposition Method), and bok-kin Jane (Box-Jenkins Method)Based on prediction values that have come to measure the accuracy of a prediction using a squared error (MSE), and mean absolute percentage error (MAPE) The time series studies the characteristics as follows: time series data that animations around the time series data, the average is only likely. Time-series data that contains both the trend and season. Based on information of agricultural products export quantity monthly since January to August include 2557 (2014) 2552 (2009) export volume of dried mushrooms. Food products from starch and sugar from the data collection of the Office of agricultural economics, cooperation of the Customs Department. The results of research to compare the forecasting techniques suitable for the time series data from studies. (1) for time series animation around the time series data on average of.Export volume of dried mushrooms. The appropriate prediction technique is a method of smoothing x, a simple fall. The service is also ok and Jane kin. (2) for a specific time series trend, which relies on time series data of the export volume of food products from wheat flour suitable forecasting technique is a method on ok, and Jane kin. Second is the smoothing method x, fall ladap label. (3) for the entire time series trend and season. Time series data on the quantity of exports of sugar. The appropriate prediction technique is a method on ok, and Jane secondary kin is the decomposition method.
