The farmer exchange rate is a comparison of the price index received and the price index paid by farmers. Forecasting the ever-changing farmer exchange rate is a reference for making a forecasting program. Many methods can be used to forecast the population, one of which is the Fuzzy Time Series method. In this study, a comparison was made between two methods, namely the Chen method and the Lee method. The data used in this research is official data from the Central Bureau of Statistics as much as 120 data from January 2010 to December 2020. This research was made by comparing two methods. The level of accuracy is a determinant of which method is better. The result of the error value obtained from the calculation with the Chen method is 1.03%, while the Lee method gets an error value of 1.01%. The researcher concluded that the Lee method is better than the Chen method based on the error value obtained.
