Grading System Recommendations for Students using Fuzzy Mamdani Logic

The use of decision making is highly needed to ease teacher in providing a grade. Grade given by the teacher to a student can be optimized by using fuzzy logic. Mamdani fuzzy method is one part of the Fuzzy Inference System that was to create a control system by synthesizing rules obtained from experienced human operators. This fuzzy system uses 2 input variables, there are student test scores and student behavior scores. Output of this system is a recommendation for the teacher to provides grade to a student. The implementation of the fuzzy Mamdani logic in grading system recommendation has no different result in manual calculating and application, indicates that the application is worth to use.
