Abstract

Logarithms are one of the mathematics lesson materials in the algebra aspect which provide many benefits in everyday life. Despite the many benefits associated with logarithms, most students think that logarithms are something difficult and not worth learning. This research aims to determine important factors in students' difficulties in understanding the concept of logarithms. The samples were 99 class X students from three public high schools in Aceh Tamiang Regency. Data was obtained using a logarithm material diagnostic test instrument based on aspects of logarithms as an object, process, function, and contextual problems. From these four aspects, we identified 17 variables that caused students difficulty in understanding the concept of logarithms. The research results show that there are five main factors that cause students difficulties in understanding the concept of logarithms. These factors are: (a) connecting square roots with logarithms, (b) connecting logarithmic and exponential functions as inverses, (c) rules of logarithmic notation, (d) logarithmic graphs, and (e) simplifying logarithmic expressions

Abstract

The need to measure complex dimensions of social and humanitarian problems such as quality of life, welfare, and health which cannot be measured using classical techniques, provides an opportunity for the fuzzy logic approach to solve these problems thanks to its ability to work within a framework uncertainty, ambiguity, and unclear information. This research aims to prioritize indicators for measuring employee well-being at the Oro Kopi Gayo company in conditions of uncertainty. Using Chang's Extent Analysis Method in the Fuzzy Analytical Hierarchy Process, this paper evaluates five main components of employee well-being: work satisfaction, organizational respect for the employee, employer care, positive/negative emotions, and intrusion of work into private life. It is hoped that the results of this research can be used as a reference in further research to determine the influence of these five criteria on employee well-being at the Oro Kopi Gayo company

Abstract

Spatial ability is an important aspect of human intelligence related to the skills of understanding, manipulating, and remembering the relationships between objects in space. This study aims to analyze the spatial abilities of 10th-grade students at SMK Negeri 1 Langsa in solving geometry problems. This study employed a descriptive qualitative approach with a sample of 20 10th-grade accounting students at SMK Negeri 1 Langsa during the odd semester of the 2025/2026 academic year. Subsequently, 3 students were selected for further analysis. The data collection techniques used included spatial ability tests, and interviews. The results showed that students’ spatial abilities fell into varying categories: high, moderate, and low. When examined by individual indicators, spatial perception achieved the highest scores, while mental rotation had the lowest scores. This indicates that students tend to be able to recognize three-dimensional shapes but still struggle to mentally visualize and manipulate the rotation of these shapes when solving geometry problems. The results of data triangulation showed consistency between the test results and the interviews, thereby strengthening the validity of the research data. Thus, it can be concluded that students’ spatial abilities in solving geometry problems have not yet developed optimally across all indicators, particularly in the aspect of mental rotation.
