Abstract

This study aims to analyze the perspectives of mathematics students on mixing aloe vera extract with weak acid solution for hair health and softness. The research method used is descriptive quantitative through the distribution of questionnaires to 43 mathematics students at Medan State University and other universities in North Sumatra. The questionnaire consists of 19 statements covering aspects of knowledge (12 items), environmental awareness (4 items), and psychomotor (4 items) with a Likert scale of 1-5. The results showed that the majority of respondents had good knowledge about the benefits of aloe vera for hair care (mean = 4.02), but the understanding of weak acid solution and its mechanism of action was still moderate (mean = 3.12). The environmental awareness aspect showed a high value (mean = 3.76) which reflects the tendency of students to choose natural products. Meanwhile, the psychomotor aspect showed a moderate value (mean = 3.44), which indicates the limitations of respondents' skills in applying hair care products optimally. This study found a positive correlation between knowledge about natural ingredients and the tendency to use natural-based products for hair care. The results of this study are expected to be the basis for developing hair care product formulations based on natural ingredients that suit the needs and preferences of students.

Abstract

Problem-solving ability is one of the essential competencies in mathematics learning, particularly in algebra. However, in the problem-solving process, students often make errors that indicate difficulties in understanding concepts and determining appropriate solution strategies. This study aims to analyze students' errors in solving algebra problems based on the problem-solving stages proposed by Krulik and Rudnick, which include reading and thinking, exploring and planning, selecting a strategy, finding an answer, and reflecting and extending. This research employed a descriptive qualitative approach involving 24 ninth-grade junior high school students. The data were collected through a problem-solving test consisting of five algebra questions and analyzed based on the stages of problem solving. The results indicate that students' problem-solving abilities vary at each stage. A total of 83% of students were able to understand the problem at the read and think stage, 75% were able to plan the solution at the explore and plan stage, and 71% were able to select an appropriate strategy at the select a strategy stage. At the find an answer stage, the success rate decreased to 67% due to procedural errors in algebraic calculations. The lowest level of success occurred at the reflect and extend stage, where only 50% of students rechecked their answers. The dominant errors found include procedural errors in calculations, conceptual errors in understanding algebraic concepts, and difficulties in translating word problems into mathematical models.

Abstract

This study aims to investigate the difficulties experienced by students in understanding matrix material, with a particular focus on matrix multiplication. The research was conducted with 13 students from grade XI of Al Maksum Private High School Medan. To obtain comprehensive data, researchers used a combination of interviews and written tests. These instruments were designed to explore students’ conceptual understanding as well as the procedural aspects of solving matrix problems. The data collected were then analyzed using the Miles and Huberman model, which involves three key steps: data reduction, data display, and drawing conclusions. The results of the analysis revealed that students encountered various obstacles in learning matrices, especially in performing matrix multiplication. The main difficulties stemmed from several factors, including a lack of understanding of the basic concepts and rules that govern matrix operations, particularly multiplication. Additionally, many students made calculation errors, especially when dealing with positive and negative numbers. Some students also demonstrated low confidence in their answers, which may have led them to second-guess correct solutions. Moreover, insufficient attention to detail when performing step-by-step calculations often resulted in inaccurate final answers. These findings highlight the importance of reinforcing conceptual understanding, improving arithmetic accuracy, and building students’ confidence through targeted instructional strategies and practice. Such improvements may help students overcome their current learning obstacles in matrix-related topics.
