Abstract

This study aims to develop and analyze the SDF mathematical model in addressing difficulties faced by students in completing their theses at the Mathematics Department, Universitas Negeri Makassar, in 2023. The SDF model is derived from the SIR model, which is commonly utilized to analyze disease spread, by adapting specific assumptions relevant to the students' circumstances. The analysis of the model focuses on determining equilibrium points, model stability, and the basic reproduction number , which serves as a critical parameter in understanding the dynamics of the issue's spread. Data for the study were collected from students in the Mathematics Department, Faculty of Mathematics and Natural Sciences, Universitas Negeri Makassar, and were used for model simulations employing Maple 18 software. The analysis results indicate a basic reproduction number value of , implying that the number of students experiencing difficulties in completing their theses is expected to increase over time without intervention. These findings provide valuable insights for the university to comprehend the factors influencing the thesis completion rates among students. It is anticipated that this study can inform the design of more effective strategies and interventions to assist students in overcoming their challenges. The SDF model can also serve as a reference for similar studies in other contexts

Abstract

This study positions ethnomathematics as a framework for understanding mathematics as an embedded component of cultural practices and indigenous knowledge systems. Indonesia’s rich ethnic diversity provides a wide spectrum of traditional architectural forms containing implicit mathematical structures. This research aims to investigate the architectural structure of the Boyang traditional house through the perspective of projective geometry and House Theory, particularly in the construction of house diagrams, building numbering systems, and the formulation of projective coordinates. The study employed a descriptive qualitative approach by representing one-point, two-point, and three-point perspective views into projective geometric diagrams. The findings reveal that the Boyang house can be classified as a Type IV simple house based on House Theory classification. Furthermore, the resulting building numbers are identified as . The analysis demonstrates that the architectural structure of the Boyang house can be formally modeled within the framework of projective geometry, thereby illustrating the existence of mathematical reasoning embedded in local architectural traditions. These findings contribute to the development of ethnomathematics by strengthening the integration between formal mathematical concepts and cultural heritage studies, while also providing a theoretical foundation for interdisciplinary research in mathematics, architecture, and indigenous cultural studies.
