Pengembangan media pembelajaran matematika berbasis website dengan masalah kontekstual
Full text linkContextual problem solving skills are very important for students to master. However, many students still have difficulty in problem solving. Therefore, media development is needed that can improve these skills, one of which is through website development. The purpose of this study is to develop a website as a mathematics learning media that raises contextual problems for junior high school/Islamic junior high school levels. This development research uses the Research and Development (RD) method. The methods used to collect data are observation, interviews and documentation studies for initial data collection, questionnaires for assessing the feasibility of the developed media, and evaluation tests for effectiveness tests. The subjects of this study consisted of 4 material experts, 3 Indonesian language experts, and 5 media experts. This study obtained very valid results in terms of material with a value of 95.14%. In terms of Indonesian, the results were very good with a value of 88.64%. Meanwhile, in the media test, the results were very good with a value of 93.47%. Student assessments in the initial trial stage obtained very good results of 79.92%. Student assessments in the field trial obtained very good results of 82.76%. Student assessment on dissemination got very good results of 82.82% and the effectiveness test on website-based mathematics learning media with contextual problems got good results of 77.01%. For other researchers who focus on the development of learning media, especially those based on websites, it is necessary to develop the security of the website being developed by validating the registered email
Pengembangan e-modul interaktif berbasis canva untuk meningkatkan kemampuan pemecahan masalah matematis pada materi barisan dan deret aritmatika
Full text linkMathematical problem-solving skills are very important for students to master. However, students' problem-solving skills are still relatively low, one of which is in the material of arithmetic sequences and series. So it is necessary to develop teaching materials in the form of e-modules based on Canva. This study aims to develop an interactive e-module based on the Canva application as a mathematics learning medium for the topic of arithmetic sequences and series, with the goal of improving students' mathematical problem-solving skills. The research employs the Research and Development (RD) method using the ADDIE development model (Analyze, Design, Development, Implementation, Evaluation). The research subjects were 11th-grade students at SMAN 2 Kuningan. Validation was carried out by two subject matter experts and two media experts, while practicality was assessed through questionnaires completed by students and teachers. The validation results show that the interactive e-module has a very high level of validity, with a percentage of 94.67% from the subject matter experts and 91.54% from the media experts. The practicality of the e-module is also considered very practical, with a percentage of 86% from students and 90% from the teacher. The effectiveness of the e-module was evaluated based on the improvement of learning outcomes through the N-Gain test, comparing pre-test and post-test scores. The N-Gain score of 0.61 (moderate category) indicates that the use of the Canva-based interactive e-module provides a significant and effective improvement in students’ mathematical problem-solving abilities in the topic of arithmetic sequences and series. The results of the study show that the Canva-based interactive e-module is valid, practical, and effective in enhancing students' mathematical problem-solving skills

Analisis kemampuan literasi numerasi dengan konten aljabar dan bilangan siswa kelas VIII
Full text linkMinimum Competency Assessment (MCA) is an assessment of competencies such as reading literacy and numeracy. Basically, literacy in Indonesia is low due to the lack of interest in reading and the numeracy level of Indonesian students is still at the bottom of the rankings. The purpose of this study is to describe the level of students' numeracy literacy skills and identify obstacles and aspects of abilities that need to be improved, with sampling at SMP Negeri 2 Pekalongan in the 2024/2025 school year using descriptive qualitative research methods. The research subjects consisted of 25 students who were given tests related to numeracy literacy with algebra and number content. Based on the test results, 8 students were categorized as high, 7 students as medium, 9 students as low and 1 student as very low. From the test results, 4 students were selected to take part in the interview from each category. Students in the high and medium categories were able to explain the essence of a reading and the problem solving process in the problem. While students in the low and very low categories were not able to. To improve students' ability in numeracy literacy test, teachers are advised to provide many practice problems equivalent to AKM with algebra and number content as well as literacy activities in learning

Statisticam approaches for consistency index in analytical hierarchy process
Full text linkThis study presents a method for estimating a new Random Index (RI) value to determine the acceptance or rejection of matrices in the Analytic Hierarchy Process, using the Saaty scale. The proposed RI values are compared to the matrix consistency levels of other researchers who conducted experiments with similar numbers and matrix orders. In the case of 1000 experiments, our values showed a slight improvement compared to those of Golden and Wang. For the 2500-experiment case, our values were similar to those reported by Lane and Verdine. Lastly, in the 100,000-experiment case, our values exhibited a slight improvement compared to those obtained by Alonso and Lamata. We welcome further suggestions and encourage future research in this area
Systematic Literature Review: Resiliensi matematis dalam pembelajaran matematika
Full text linkStudents need internal or external support in learning mathematics; the main focus of this study discusses internal factors regarding students' mathematical resilience. This study aims to examine the definition, indicators, and role of mathematical resilience in mathematics learning. Systematic Literature Review (SLR) is a research method used in this study. Before being adjusted to the criteria, there were 38 articles, but only 14 articles in the last 5 years met the criteria as material for reviewing the discussion related to mathematical resilience. The results of the study show that (1) mathematical resilience can be determined to be a non-intellectual capacity of students in mathematics learning, especially the capacity to survive and form a positive mindset in facing all challenges at a difficult level when learning mathematics in class; (2) indicators of mathematical resilience that are often used come from Sumarmo, Johnston-Wilder et al., and Hutauruk; (3) the role of mathematical resilience in learning is to help students control affective abilities in training the abilities needed when learning mathematics. In further research, it is hoped that we will be able to link students' mathematical resilience with appropriate learning models
