Abstract

This research aims to identify and map available evidence regarding the role of mathematics (such as linear algebra, discrete mathematics, computational modeling) in supporting the development of Artificial Intelligence. Mathematics is a key foundation for the development and understanding of computer science, and is a universal language used for analyzing, designing, and optimizing various aspects. Discrete mathematics, on the other hand, plays a crucial role in the foundation of artificial intelligence, particularly in the field of Artificial Intelligence. Its principles underlie many algorithms and processes that Artificial Intelligence systems rely on. Furthermore, many other mathematical concepts and principles are also used in computer science, such as propositional logic, Boolean algebra, graph theory, number theory, statistics, and algorithm analysis. Thus, computer science and mathematics are clearly closely related and complement each other. Research findings, including identifying and mapping available evidence, demonstrate that mathematics is not merely a tool, but rather the backbone of all modern Artificial Intelligence technology developments currently in use.

Abstract

The purpose of this study was to determine whether there is an effect of implementing Contextual Teaching and Learning (CTL) based on Augmented Reality in developing students’ spatial visualization abilities and geometric reasoning on solid geometry material for eighth-grade students at SMPN 1 Bandar Pulau. This research used a quasi-experimental method with a Two Group Pre-Test and Post-Test research design. The population of this study consisted of all eighth-grade classes, totaling four classes. The research sample consisted of two classes selected through purposive sampling determined by the school. The control class used the CTL learning model, while the experimental class used Augmented Reality-based contextual learning. After the learning process was completed, the post-test results showed that the average score of the experimental class was 71.696 and the control class was 67.048. The results of the t-test obtained t_count = 1.708 > t_table = 1.669, therefore Hₐ was accepted. In addition, this study also used questionnaires to measure students’ perceptions of Augmented Reality-based contextual learning. The questionnaire results indicated that the majority of students gave positive responses toward the use of AR in learning. A total of 42.9% of students strongly agreed and 43.4% agreed that contextual learning with AR made the learning process more interesting, enjoyable, and helpful in understanding solid geometry concepts. Thus, it can be concluded that there is an effect on students’ learning outcomes through the use of Augmented Reality-based contextual learning in developing students’ 3D visualization abilities and geometric reasoning.

Abstract

Electrical installations in houses often experience cable waste due to suboptimal planning. This research applies graph theory with the Minimum Spanning Tree (Prim) algorithm to optimize electrical installation design in type 36 houses. The system is modeled as a weighted graph with vertices representing load points and edges representing cable routes. Results show the conventional method requires 31.50 meters of cable, while Prim's algorithm produces only 21.07 meters, achieving 33.11% savings (10.43 meters). The resulting network structure is acyclic and simpler, making it easier to implement and maintain. The design has been validated according to PUIL 2000 and SNI 04-6989.5-2000 standards. This research provides a systematic methodology for designing efficient, safe, and cost-effective electrical installations applicable to the residential construction industry.

The population of this study consisted of all grade VIII students at UPTD SMP Negeri 3 Silau Laut, while the sample consisted of two classes selected using purposive sampling techniques, namely the experimental class and the control class. The experimental class was taught using the Malay culture-based Contextual Teaching and Learning model assisted by the GeoGebra application, while the control class used the expository learning model. Data collection techniques included mathematical numeracy literacy tests, observation, and documentation. Data analysis was carried out using normality tests, homogeneity tests, and hypothesis tests. The results showed that the implementation of the Malay culture-based Contextual Teaching and Learning model had an effect on students’ mathematical numeracy literacy abilities. Students in the experimental class showed improvement in analyzing information, using mathematical symbols, performing arithmetic operations, and interpreting problem-solving results compared to students in the control class. In addition, learning integrated with Malay culture and the use of the GeoGebra application were able to increase students’ learning motivation, activeness, and understanding of mathematical concepts in a more contextual and meaningful way. Therefore, the Malay culture-based Contextual Teaching and Learning model is effective as an alternative mathematics learning model to improve students’ mathematical numeracy literacy abilities.
