Abstract

Objective and accurate scholarship recipient selection is essential in the education sector, particularly at the elementary school level such as SDN 100111 Hutatunggal. This research develops a decision support system using the Mamdani fuzzy logic method to assist the school in evaluating students’ eligibility for scholarships based on three main criteria: parental income, number of dependents, and academic grades. Each criterion is modeled using triangular membership functions and processed through 27 fuzzy rules to generate a final eligibility score. The system is implemented using MATLAB R2025a, complete with a user-friendly graphical user interface (GUI) for ease of operation. Testing results demonstrate that the method provides consistent, fair, and accountable decisions. Moreover, the system enhances time efficiency in the selection process and reduces subjectivity in evaluation. Therefore, the application of Mamdani fuzzy logic proves to be an effective tool for decision-making in determining scholarship recipients in primary school settings, particularly at SDN 100111 Hutatunggal.
