Penggunaan Metode Pemulusan Eksponensial Untuk Peramalan Nilai Ekspor Non Migas Di Indonesia
The exponential smoothing forecasting method is one of the time series data
forecasting methods. This study uses non-oil and gas export data in Indonesia for
the period January 2015-May 2021 indicating that there are elements of trends and
seasonality. Based on the characteristics of the time series, the data obtained were
then analyzed using Holt's double exponential smoothing method and triple
exponential smoothing consisting of multiplicative and Holt-Winters additives. The
best model selection can be done by choosing the minimum forecast error value.
This study shows that the additive Holt-Winters method is the best forecasting
method that has a minimum forecast error value. The forecast results using this
method indicate that the value of non-oil exports will increase for the next period.
