Abstract

This study aims to analyze students' understanding and difficulties in probability in grade XII of SMA Negeri 1 Tanjung Morawa and identify the contributing factors. The research method used is descriptive with quantitative and qualitative approaches. Quantitative data were obtained from the results of the problems given to students, then analyzed to determine the level of understanding, types of errors, and the percentage of difficulties experienced. Meanwhile, qualitative data were obtained through interviews with subject teachers to deepen information regarding the obstacles faced by students and the learning strategies implemented. The results showed that most students experienced difficulties in determining the sample space, applying probability formulas, and interpreting calculation results. Contributing factors include limited understanding of basic concepts, a lack of variety in practice questions, and learning that still focuses on procedures. Based on these findings, the researcher offers solutions in the form of contextual learning, conceptual reinforcement through class discussions, and the provision of step-by-step practice questions with teacher guidance. This research is expected to contribute to teachers in improving the effectiveness of probability learning in schools.

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.
