Tourism plays a pivotal role in the Indonesian economy. As a foreign exchange reserves, the performance of tourism sector is determined by our ability to bring in as many foreign tourists as possible to Indonesia. Riau Islands is the foreign tourism gate which is strategically located as a favorable foreign tourist destination. This journal aims to determine proper forecasting methods for the existing data patterns and to provide more accurate forecasting results. The methods used include Time Series Additive and Multiplicative as well as Holt Winter Additive and Multiplicative. From these four methods, the forecasting is calculated using the Holt Winter Multiplicative method as it has the smallest MAE (Mean Absolute Error) value compared to the other three methods.
