Abstract

This study aims to test the compatibility of structural equation (SEM) models to determine the relationship between mathematical reasoning ability and geometry problem solving ability. Using an ex-post facto research design, this study took a random sample of 100 students from a total of 296 mathematics education student population at a university in Lubuklinggau. Data were collected through mathematical reasoning tests and geometry problem-solving tests, then analyzed using the Lisrel 8.8 and SPSS programs. The results of the analysis show a very significant path coefficient, which proves that mathematical reasoning ability has a positive direct relationship with geometry problem-solving ability. This means that an increase in reasoning skills will be followed by an increase in the ability to solve geometry problems. In conclusion, this study confirms the existence of a direct relationship between the two variables, where mathematical reasoning ability contributes 15.13% to the improvement of geometry problem-solving ability. Keywords: Ability, Mathematical reasoning, Geometric Problem Solving, SEM, Lisrel

Abstract

The peri-urban area of Semarang City, particularly Pakintelan Village, Gunungpati District, has experienced rapid residential growth over the past decade. However, this growth has not been accompanied by adequate waste management infrastructure, especially for household organic waste. Many residents still dispose of or burn organic waste such as food scraps and vegetables, which negatively impacts the environment and public health. To address this issue, this community service initiative aimed to enhance residents' capacity to process organic waste into environmentally friendly and economically valuable products. The methodology involved in-depth interviews with neighborhood leaders to identify key issues, followed by a literature review to develop educational materials, and concluded with practical training on producing eco-enzyme from household kitchen waste. The program ran smoothly and received enthusiastic participation from the community. Residents showed a strong interest in applying eco-enzyme production in their daily lives. Moving forward, further research is recommended on developing a community-based organic waste management system, as not all residents have the space or time to process waste independently

Abstract

Mathematics anxiety will cause students to become depressed during mathematics learning. This results in students not being able to receive and understand the lesson well. The next thing that happens is that students' solving abilities cannot develop and eventually their learning outcomes become less complete. The purpose of this study was to analyze the effect of mathematics anxiety on students' problem solving abilities. This study uses the SLR (Systematic Literature Review) method. The result of this research is the effect of math anxiety on problem solving ability is negative. Based on the studies reviewed, it can be concluded that the high level of students' mathematics anxiety means that the problem solving ability produced is low, and vice versa. Problem solving ability is strongly influenced by students' mathematical anxiety. Then the math anxiety arises, one of the causes is that students are less able to understand the concept of the material presented. So as a teacher or teacher, the first thing to fix is ​​to instill in students not to be afraid of mathematics, because mathematics is not as difficult as imagined.

Abstract

This study aims to systematically analyze the trends, focus, and effectiveness of the implementation of Problem-Based Learning (PBL) assisted by learning media on improving students' mathematical literacy in Indonesia. The approach used is a Systematic Literature Review (SLR) with reference to the guidelines of Kitchenham and Charters. Data were collected from 26 scientific articles published between 2021 and 2025 obtained through the Google Scholar database. Article inclusion criteria in this study were set to ensure the relevance and quality of the sources, namely they must be journal publications indexed by Sinta or Google Scholar, specifically discussing students' mathematical literacy in the implementation of Problem-Based Learning assisted by learning media, and written in Indonesian or English. Analysis was conducted on aspects of the objectives, types and designs of the research, types of media used, learning materials, educational levels, and the effectiveness of the implementation of media-assisted PBL. The results of the review indicate that most studies focused on improving mathematical literacy using a quantitative approach through a quasi-experimental design and the ADDIE model. Digital learning media, particularly GeoGebra, is the most widely used and has proven effective in fostering understanding of abstract concepts. Furthermore, studies show that high school and vocational high school (SMA/SMK) students and geometry are the most frequently researched topics. Overall, the integration of PBL with learning media has been shown to effectively improve mathematical literacy, critical thinking skills, and student engagement, making it an innovative strategy for strengthening the quality of mathematics learning in Indonesia

Abstract

Student dropout is a serious problem that can affect the quality of education and operational efficiency of higher education institutions. Early prediction of potential students who will dropout is essential to develop appropriate intervention strategies, so as to increase graduation rates and reduce the negative impact on academic continuity. A better model for student dropout prediction becomes an objective of this research. The method used in this research is to improve the performance of machine learning models through the selection of optimal hyperparameters. The research methodology consists of several stages, including data preprocessing, handling imbalanced data, model training, and performance evaluation. There are three machine learning models used in this research, namely XGBoost, AdaBoost, and Random Forest. The selection of optimal hyperparameter values is carried out using the Random Search and Grid Search methods. Model evaluation is conducted using k-fold cross-validation and multiple evaluation metrics, including accuracy, precision, recall, and F1-score. As part of the important results, the combination of XGBoost and Random Search produced the best performance with 91.18% accuracy, indicating that hyperparameter optimization significantly improves predictive performance. The findings of this research explicitly contribute to the field of informatics, particularly educational data mining, and provide insights for educational institutions to identify high-risk dropout students more accurately.
