Abstract

This study aims to compare the performance of Random Forest and K-Nearest Neighbors (KNN) algorithms in classifying daily weather categories at Kemayoran Meteorological Station, Jakarta. The data used were BMKG observation data from 2017 to 2023, with classification targets consisting of No Significant Weather, RA, TS, and TS,RA. The variables included temperature, rainfall, air pressure, humidity, wind speed, sunshine duration, wind direction, and month. The data were preprocessed and divided into training and testing sets using an 80:20 ratio. The results showed that Random Forest achieved an accuracy of 78% with a weighted average F1-score of 0.75, while KNN achieved an accuracy of 65% with a weighted average F1-score of 0.59. Random Forest performed better in classifying dominant weather categories, although both algorithms still had limitations in identifying minority categories, particularly TS. These findings indicate that Random Forest is more suitable for daily weather classification based on BMKG observation data in urban areas.   Keywords: K-Nearest Neighbors; Random Forest; Weather Classification

Abstract

This study aims to analyze the existence of eigenvalues in the min-plus algebra matrix structure and to explain their relevance to shortest path problems in defense logistics systems. The method used is a literature study of sources discussing the theory of eigenvalues, eigenvectors, precedence graphs, minimum mean weight of elementary circuits, and the application of eigenvalues in the min-plus algebra matrix structure to shortest path determination. The results show that eigenvalues in the min-plus algebra matrix structure always exist due to the existence of the minimum mean weight of elementary circuits in the precedence graph of the min-plus algebra matrix structure. These eigenvalues have a mathematical interpretation as the minimum cycle time of a system, making them relevant for application in optimizing defense logistics distribution routes. The conclusion of this study shows that the existence of eigenvalues in the min-plus algebra matrix structure can serve as a mathematical basis for more efficient shortest path planning, particularly in minimizing delays in logistics distribution in the defense sector.   Keywords: Min-plus Algebra, Precedence Graph, Defense Logistics, Eigenvalues, Shortest Path

Abstract

This study aims to examine the development of a guided inquiry-based mathematics e-module and its impact on students' mathematical competence, which includes cognitive aspects such as creative thinking and mathematical communication, as well as affective aspects such as self-confidence. The method used was a Systematic Literature Review (SLR) with the PRISMA protocol, which synthesized 9 relevant articles from the Google Scholar database through the Publish or Perish application in the 2020–2026 period. The results showed that the e-module development predominantly used the ADDIE and 4D models with a high level of validity and practicality. The integration of the guided inquiry model in digital media has been proven to significantly improve students' creative thinking skills through independent exploration and problem-solving processes. In addition, the use of supporting techniques such as mind mapping and the STEM approach strengthens the effectiveness of learning in building student independence and self-confidence. This study concludes that the guided inquiry-based e-module is an innovative solution that is highly relevant to the spirit of the Independent Curriculum to create student-centered and technology-adaptive mathematics learning.   Keywords: Flat Shapes, Guided inquiry, Independent Learning, Interactive Media

Abstract

This study aims to analyze students' perceptions of polyhedral constructions in terms of the Van Hiele theory of geometric thinking levels. The method used was descriptive research with a qualitative approach involving 26 ninth-grade students of SMP YAPIS Manokwari. Data were collected through tests and interviews. The tests were used to identify students' geometric thinking levels, while the interviews were conducted to explore students' perceptions of polyhedral constructions and to verify the test results. The data were analyzed through data reduction, data display, and conclusion drawing. The findings revealed that the students were at the visualization and analysis levels. Students at the visualization level tended to understand three-dimensional figures based on their visual appearance and observable shapes, whereas students at the analysis level were able to identify component solids and recognize several geometric properties used in problem solving. However, students at both levels still experienced difficulties in understanding the relationships among the parts of composite solids comprehensively. In conclusion, students' perceptions of polyhedral constructions develop in accordance with their geometric thinking levels. Therefore, geometry instruction should be adjusted to students' stages of thinking in order to support the development of a deeper understanding of geometric concepts.   Keywords: Geometry, Perception, Van Hiele Theory, Level of thinking
