Abstract

The community engagement activity carried out by the teaching team from the Mathematics Program of the Faculty of Mathematics and Natural Sciences at Universitas Mataram to SMAN 1 Selong has successfully introduced students to the importance of statistics and game theory in decision-making. Through stories and real-life cases, students are encouraged to consider factors such as averages and standard deviations in making informed decisions. They also learn about the story of John Nash, who discovered game theory, and compare it to the economic principles of Adam Smith. Students realize that collective interests can lead to better outcomes than personal interests. In the case of The Prisoner's Dilemma, students also see the importance of game theory in the context of collective decision-making. Overall, this activity helps students understand the importance of statistics and game theory in the decision-making process.

Abstract

The Science materials on astronomy, particularly solar eclipses, are often perceived as abstract by junior high school students because the objects of study cannot be directly presented in the classroom. The limitations of two-dimensional (2D) media lead to low conceptual understanding and scientific literacy. This study aims to develop a solar eclipse diorama as an economical and interactive alternative for science learning media. The research method employed is Research and Development (R&D) using the 4D model (Define, Design, Develop, Disseminate). The research was conducted up to the Develop stage, limited to product functionality testing without extensive field trials. The research subjects involved an analysis of the characteristics of junior high school students in the transition from concrete to formal operational stages. The results showed that the diorama developed using styrofoam, wire, and LED lights effectively visualized the relative positions of the Earth, Moon, and Sun and the formation of umbra and penumbra shadows. The diorama functions well in simulating earth rotation, the lunar revolution, and the eclipse phenomena. This study concludes that the solar eclipse diorama is suitable for use as a practical and efficient alternative learning medium, especially for schools with limited laboratory facilities, to increase students' interest and conceptual understanding.

Abstract

Pengetahuan lokal yang tumbuh melalui interaksi masyarakat dengan budaya dan lingkungan dapat dimanfaatkan sebagai sumber pembelajaran IPA yang kontekstual. Taman Wisata Alam Suranadi memiliki ritual air suci atau melukat yang mengandung nilai spiritual, budaya, dan ekologis. Penelitian ini bertujuan mengidentifikasi pengetahuan lokal masyarakat mengenai ritual air suci, menganalisis keterkaitannya dengan konservasi lingkungan, serta merekonstruksinya menjadi konsep-konsep IPA yang relevan untuk pembelajaran berbasis etnosains. Penelitian menggunakan pendekatan kualitatif eksploratif dengan perspektif etnografi. Data dikumpulkan melalui observasi langsung, wawancara semi-terstruktur, dokumentasi, dan studi literatur. Informan ditentukan secara purposive, meliputi pengelola kawasan, tokoh agama, masyarakat lokal, dan pengunjung. Data dianalisis melalui reduksi data, penyajian data, dan penarikan kesimpulan, sedangkan keabsahan data diuji melalui triangulasi sumber dan teknik. Hasil penelitian menunjukkan bahwa ritual air suci mengandung nilai konservasi lingkungan berupa penghormatan terhadap sumber mata air, pemeliharaan kebersihan kawasan, pelestarian vegetasi, serta kepatuhan terhadap aturan di kawasan sakral. Pengetahuan lokal tersebut dapat direkonstruksi menjadi konsep ekosistem, komponen biotik dan abiotik, konservasi dan kualitas air, pencemaran lingkungan, serta interaksi manusia dengan lingkungan. Penelitian ini menyimpulkan bahwa kawasan Suranadi berpotensi dimanfaatkan sebagai sumber pembelajaran IPA berbasis etnosains yang kontekstual sekaligus mendukung kesadaran lingkungan dan penghargaan terhadap kearifan local.

Abstract

The Korteweg-de Vries (KdV) equation is a nonlinear partial differential equation that has a key role in wave physics and many other disciplines. In this article, we develop numerical solutions of the KdV equation using the finite difference method with the Crank-Nicolson scheme. We explain the basic theory behind the KdV equation and the finite difference method, and outline the implementation of the Crank-Nicolson scheme in this context. We also give an overview of the space and time discretization and initial conditions used in the simulation. The results of these simulations are presented through graphical visualizations, which allow us to understand how the KdV solution evolves over time. Through analysis of the results, we explore the behavior of the solutions and perform comparisons with exact solutions in certain cases. Our conclusion summarizes our findings and discusses the advantages and limitations of the method used. We also provide suggestions for future research in this area.
