ABSTRACT The database system that available at the moment only can save the certain (crisp), deterministic and precision. Whereas, in the real condition we often need a vague data to make decision. We can use fuzzy logic to make decision that have variables with vague values. This final project will implement fuzzy logic into the query, which is called Fuzzy Daabase Query. That is, a query that has a variable valued fuzzy variables. To get information about the performance of employees, then the required criteria attendance and performance criteria that employees valued ambiguous. Data is based on the criteria of degree of membership valueof each employee that has been processed with the method of fuzzy Tahani. Whit the end of this task is expected to help obtain information about the performance of employees and can provide encouragement for employees to become better.
