## Abstract
This study aims to examine the accuracy of the time-invariant fuzzy method in forecasting the number of ship passengers at the port of Makassar. Forecasting helps a company establish the number of passengers to come, anticipate their increase, and provide policies for addressing the problem. The Time-Invariant Fuzzy, whose relationship does not depend on time t, was used by utilizing fuzzy sets as historical data. In general, this method has two essential aspects, including the use of historical or actual data and relations. The data used was obtained from the number of ship passengers at Makassar Port from January 2012 to December 2020. The results showed that the Mean Average Percentage Error (MAPE) value in the training and the testing data is 7.9% and 6.8%, respectively. This means that the method is very accurate in predicting ship passengers at Makassar Port.
