Abstract

This study aims to analyze the correlation between temperature, humidity, and Rainfall at the Geophysics Station of Padang Panjang from 2020 to 2023. Monthly data from the Meteorology, Climatology, and Geophysics Agency (BMKG) was used to evaluate the relationship between these meteorological variables. Statistical analysis, including correlation and multiple linear regression, was conducted using SPSS version 22. The results show a significant negative correlation between Rainfall and temperature, indicating that temperature tends to decrease as rainfall increases. In contrast, a positive correlation between Rainfall and humidity suggests that higher humidity levels are associated with increased Rainfall. However, the regression analysis reveals that temperature and moisture explain only 16.76% of the variation in Rainfall, indicating the potential influence of other factors not included in the model.

Abstract

This study aims to evaluate the implementation of advanced calculus courses assisted by GeoGebra using the CIPP model. This evaluation assessed the relevance, effectiveness, and results of applying GeoGebra as an interactive learning medium. The research approach was descriptive quantitative, with data collection through questionnaires and observations. The research subjects were 36 students who attended advanced calculus courses at FMIPA Universitas Negeri Padang in the July–December 2024 semester. The evaluation results show that in the context aspect, the use of GeoGebra is aligned with the curriculum objectives that support the mastery of advanced mathematical concepts and visualization skills. Regarding input, lecturers have basic competence in using GeoGebra, but not all students are familiar with this software. In terms of process, GeoGebra-assisted learning is interactive, although it is constrained by students’ adaptation time to the software. In terms of product, the evaluation results showed increased students’ analytical skills and conceptual understanding, although the increase in exam results was not significant overall. The findings recommend the need for intensive training for lecturers and students related to the use of GeoGebra, the provision of technology-based learning guides, and adjustments to lecture strategies to maximize the effectiveness of GeoGebra in supporting advanced calculus lectures.

Abstract

Determining the shortest path from one point to another (destination) is a problem often encountered in life. With the development of science and technology, the problem of finding the shortest path can be solved using various algorithms. The algorithm that is often used to find the shortest route is the Bellman-Ford algorithm. The Bellman-Ford algorithm requires initial location parameters and a destination as input to determine the shortest path. The algorithm's results provide the shortest distance along with the route from the initial location to the destination. Applying the Bellman-Ford Algorithm provides the shortest distance as a solution to the problem. This research determines the shortest path from the origin to the destination point, modeled by a weighted graph. The Bellman-Ford algorithm starts the iteration by updating the distance at each vertex if a shorter distance is found.

Abstract

This study aims to analyze the implementation of Merdeka Curriculum in mathematics learning in junior high schools based on Jean Piaget's cognitive development theory. The Merdeka Curriculum is designed to provide freedom for educators to arrange learning relevant to student needs, especially in mathematics subjects, which are often considered challenging. This research uses a qualitative approach with a case study type. The subject is a mathematics teacher. Data were obtained through document analysis and interviews, then analyzed descriptively through data reduction, data presentation, and conclusion drawing. To ensure data validity, source triangulation was carried out. The results showed that implementing the Merdeka Curriculum in mathematics learning supports students' formal operational cognitive development stage. The project-based approach and problem-solving at the core of the Merdeka Curriculum can develop logical, abstract, and analytical thinking skills essential in mathematics. However, several obstacles were found in the implementation, such as teachers‘ lack of understanding of learning strategies by students’ cognitive development stage, and limited interactive learning facilities. This research recommends comprehensive training for mathematics teachers to improve their ability to implement cognitive development-based learning strategies and the provision of adequate supporting facilities. With the right strategy, implementing the Merdeka Curriculum in mathematics learning in junior high schools can be more optimal in improving students' cognitive abilities.
