The purpose of this research is to make a tidal geographic information system application using fuzzy logic. The variables used for the fuzzy method are sea level and time variables. Application testing uses a blackbox, user acceptance test to test the application to the user directly and confusion matrix for method testing. The results of this study are in the form of fishing recommendations for fishermen based on sea level information and the time of the tides.} }
