Abstract

The process of determining scholarship eligibility often faces challenges related to subjectivity and uncertainty in assessment criteria, which can result in inaccurate and unfair decisions. Scholarship selection generally involves multiple criteria, such as academic achievement, family economic conditions, and supporting factors that are difficult to evaluate using conventional decision-making methods. Therefore, an appropriate decision support approach is required to handle such uncertainty effectively. This study aims to implement the Fuzzy Mamdani method in a decision support system to determine scholarship eligibility more objectively and accurately. The research method consists of data collection, fuzzification of input variables, formulation of fuzzy rules, inference using the Mamdani approach, and defuzzification using the centroid method to obtain a crisp eligibility value. The results show that the Fuzzy Mamdani method is capable of producing flexible eligibility scores by considering the degree of membership of each criterion. The generated output reflects real conditions more comprehensively compared to traditional methods. The implementation of this method can assist decision-makers in improving transparency, consistency, and fairness in scholarship selection. This research is expected to contribute to the development of intelligent decision support systems in the field of educational assessment.

Abstract

The rapid development of technology has encouraged the creation of automated systems to improve efficiency and convenience in daily life, especially in controlling electrical devices. This study aims to design and implement a smart home light control system based on Android using Arduino Uno and a 5V relay, with Bluetooth communication as the interface between the smartphone and the microcontroller. The research method includes hardware design, software development, and system testing. The system was tested for its ability to receive ON and OFF commands from the Android application, the responsiveness of the relay, and the stability of Bluetooth communication within a range of approximately 10 meters. The results show that the system can control the lamp effectively and reliably, with fast response time and minimal communication errors. This implementation demonstrates a practical, low-cost solution for home automation, providing convenience, energy efficiency, and flexibility for users. The findings suggest that such systems can be further developed to include multiple lamps or integrated with IoT networks for enhanced smart home applications.
