Abstract

This study aims to analyze drug inventory control at Kasih Clinic using the ABC method with the help of POM-QM software for Windows. Based on the Pareto principle, the results of data processing indicate that inventory items can be classified into three main groups based on the contribution of usage value to total inventory costs. Group A consists of five main drug items that contribute the most to inventory value, which is around 87.48%, despite the relatively small number of items. This group requires strict control because it has a significant financial impact. Group B includes two drug items with a cumulative contribution of usage value up to 97.55% and requires periodic monitoring with a medium priority level. Meanwhile, group C consists of most drug items but only contributes around 2.45% of the total usage value, so it can be managed with a simpler control system. Overall, the application of the ABC method has proven effective in identifying drug inventory control priorities objectively and based on economic value, thus supporting more efficient hospital inventory management decisions

Abstract

This study aims to describe the implementation of assessment and evaluation of mathematics learning outcomes in spatial geometry material in the Merdeka Curriculum at SMA Negeri 1 Girsang Sipangan Bolon. The study used a descriptive qualitative approach with data collection through observation, interviews, and document analysis. The results of the study indicate that teachers have implemented formative assessment, practical assessment, and context-based assignments. However, authentic assessment has not been implemented consistently, and assessment instruments still tend to focus on students' procedural abilities, so that contextual abilities have not been optimally explored. The main obstacles in the implementation of assessment include limited learning time, the administrative burden on teachers, and teachers' skills in developing and using assessment rubrics. This study concludes that the implementation of assessment on spatial geometry material has been in line with the principles of the Merdeka Curriculum, but it still requires improvement in teacher competence and institutional support from the school so that assessment can be carried out more optimally.

Abstract

This study aims to analyse the problems and evaluate the implementation of the curriculum in mathematics learning at Deli Murni Bandar Baru Junior High School. The research used a qualitative descriptive approach with mathematics teachers and related parties at the school as the research subjects. Data were collected through in-depth interviews, observation of the learning process in the classroom, and analysis of curriculum documents and teaching tools, such as teaching modules and assessment instruments. The data obtained were analysed using qualitative analysis techniques through the stages of data reduction, data presentation, and conclusion drawing. The results showed that the implementation of the curriculum was quite good in terms of planning, as demonstrated by the teachers' ability to develop teaching tools in accordance with the curriculum requirements. However, the implementation of learning and evaluation was not yet optimal. Teachers still tended to use conventional learning methods and had difficulty in implementing authentic assessment. These findings emphasised the need to improve teacher competence through continuous training so that the implementation of the curriculum could be carried out more effectively and have an impact on improving the quality of mathematics learning

Abstract

This study aims to describe the implementation of Understanding by Design (UbD) as a framework for the Merdeka Curriculum at Santo Thomas 1 High School in Medan. This study uses a descriptive approach with a mixed qualitative and quantitative design. Research data were collected through interviews with teachers, observations of teaching and learning activities, analysis of teaching materials, and measurement of teachers' perceptions using a Likert scale questionnaire. Qualitative data were analysed through data reduction, data presentation, and conclusion drawing, while quantitative data were analysed descriptively to determine the categories of UbD implementation levels. The results showed that UbD implementation was in the good category, especially in the planning and formulation of learning outcomes stages. However, the learning implementation and assessment stages still needed improvement because they were not fully consistent with the backward design principle. Overall, UbD played an important role in strengthening the quality of learning planning in the Merdeka Curriculum, but further assistance was still needed to optimise its application in all stages of learning.

Abstract

This study aims to determine the effectiveness of the GeoGebra learning medium on students’ conceptual understanding and mathematical problem-solving skills regarding the topic of systems of linear equations with three variables in the 10th grade at Budi Setia Private Vocational High School. This study employed a quantitative method using a quasi-experimental design in the form of a pretest-posttest-only control group design. The study population consisted of all Grade 10 students at Budi Setia Private Vocational High School, comprising 5 classes. The sample was determined using purposive sampling, resulting in Class X TKR as the experimental class (30 students) and Class X MP as the control class (30 students). The research instrument consisted of an essay test that had been validated for validity and reliability. Pre-test and post-test data were analyzed using normality tests, homogeneity tests, t-tests, N-Gain, and Effect Size. Calculations for the experimental class showed an average score of 77.80 for mathematical concept comprehension, while the control class had an average score of 68.07. Calculations for the experimental class showed an average score of 73.63 for mathematical problem-solving ability, while the control class had an average score of 66.73. Based on the t-test results, a significance value of 0.001 0.05 was obtained, so the null hypothesis was rejected. The GeoGebra learning tool was found to be effective because it was proven to significantly improve student learning outcomes, as evidenced by a comparison of average post-test scores between classes that used the tool and those that did not. In terms of mathematical concept comprehension, students in the experimental class taught using GeoGebra achieved an average score of 77.80, far surpassing the control class, which averaged only 68.07. This advantage was also consistently evident in the mathematical problem-solving ability indicator, where the experimental class recorded an average score of 73.63, while the control class lagged behind at 66.73. The conclusion of this study is that the GeoGebra learning medium is effective in enhancing students’ mathematical conceptual understanding and problem-solving abilities regarding the topic of systems of linear equations with three variables in Grade 10 at Budi Setia Private Vocational High School.

Abstract

This study aims to identify various factors that influence the development of higher-order thinking skills in the Master's program mathematics education department at Universitas HKBP Nommensen. The systematic AHP method allows for accurate weighting and prioritization of various factors influencing HOTS. These results provide a strong foundation for policy recommendations and educational practices aimed at enhancing higher-order thinking skills among outstanding students. The ranking results of the factors influencing HOTS among 100 outstanding students in the Master's program in Mathematics Education were analyzed using the hierarchy of one factor over another. By observing the three criteria and ten sub-criteria, it can be concluded that Criterion 2, or students, is the most influential factor in determining students' HOTS with a weight of 0.53. The second influencing factor is Criterion 1, or lecturers, with a weight of 0.13, and the least influential factor is the learning environment with a weight of 0.07. Matrix interpretation shows that the Lecturer factor (K1) is considered more important than the Student factor (K2) and the Learning Environment factor (K3) in influencing the HOTS of high-achieving students. This highlights how important lecturers are in helping students develop higher-order thinking abilities.
