Isomorphisms on Strong Fuzzy Graphs
Get PDFFuzzy graph is a graph consisting of pairs of vertices and edges that have a membership degree that contains a closed interval of real numbers on each edge and vertex. A fuzzy graph is said to be a strong fuzzy graph if the membership degree of edge with the minimum membership degree of vertex and the same membership degree of vertex for each edge with . This paper explains the properties of fuzzy graph isomorphism including weak isomorphism, co-weak isomorphism, and isomorphism in strong fuzzy graphs
Analysis of Junior High School Students' Ability to Understand Mathematical Concepts in Statistics Materials Reviewed from Gender
Get PDFMale students are different from women in acquiring, understanding and mastering mathematical concepts. This study intends to describe the ability of students to understand mathematical concepts from a gender perspective. The ability to understand mathematical concepts is analyzed from problem solving. This study applies a qualitative descriptive method. The subjects of the study were male and female students in grade IX of the Medan National Hero Private Junior High School as many as 12 people each. The research instrument used was in the form of a written test of mathematical concept comprehension ability consisting of 3 valid essay questions and an interview. The data was analyzed based on gender indicators of mathematical concept comprehension ability, namely restating concepts that have been learned, using certain procedures or operations, and applying concepts in meaningful problem solving to the concepts studied. Data are compared by gender. The results of the study showed that the ability to understand mathematical concepts of female students was better than that of male students on the indicators of restating the concepts that had been learned, using certain procedures or operations and applying concepts in meaningful problem solving to the concepts studied, which can be seen from the average achievement of female students 72.183 while male students reached an average of 58.3
Development of Figma Educational Game Based on Mathematics Computational Thinking Ability for Vocational Students
Get PDFDeveloping educational games using Figma can help educators create engaging and interactive learning media. This also applies at the vocational school level to improve learning outcomes, especially in mathematics, which students rarely favor because it is considered a complex subject. The main problem faced by vocational students related to employability still needs to be considered higher, which is caused by the lack of availability of interactive media to hone the skills desired by the work industry, including soft skills such as logical thinking and technical functions such as computational thinking. This research aims to create an educational game based on mathematical computational skills in vocational students through a Research and Development (RD) approach by applying 4 of the five stages of the ADDIE Method, namely Analysis, Design, Development, Implementation, and Evaluation. From the four stages of the ADDIE Model, an Educational Game design using Figma entitled "Train to Mathematics" has been produced by paying attention to important aspects such as material relevance, selection of designs used, user involvement, interactivity, adaptability, and skill enhancement, in designing the concept of educational games. The research results show the feasibility level through the material validation test with a percentage of 70%, and the media validation test obtained a percentage of 80%. The results of the validation test show that the development of educational games using Figma is feasible as learning media
Development of Mathematics Learning e-Modules to Improve Students' Mathematical Communication Skills
Get PDFE-modules can be used as a self-paced learning process that can help students learn systematically, interestingly, and interactively. The teaching and learning process is also not limited to an information source, this e-module can help students understand concepts better than the material taught by relevant teachers. This research uses research and development (Research and Development) is a research method used to produce certain products and test the effectiveness of products with a 4D model. The subject of this study is grades VII students at MTs. Amin Darussalam. It consists of one class that is randomly selected (random sampling), namely class VII as many as 6 students who are made into a limited field test or a small test group consisting of 20 students and an operational field test or a large test. The feasibility level of the e-module obtained a feasibility level of 81.83%, with a very feasible category. The assessment of the validity level is 81.47% with a category that is quite valid, can be used but needs minor revisions. The assessment of the practicality level is 73.25% with the practical category. The assessment of the effectiveness level of the e-module is 0.84 with the effective category
Research exploration and learning practices for prospective mathematics teachers
Get PDFIn the world of education, a study has quite a large influence on education practitioners.

In this context, researchers will explore the understanding of prospective mathematics teachers on existing research related to the practice of teaching mathematics prospective teachers. The research method used in this study is a quantitative research method with the type of research used in this research is correlational. The results of this study are in line with the research objectives, namely wanting to see whether there is an influence on research with learning practices for prospective mathematics teachers. The data shows that there is an influence between research on learning practices for prospective mathematics teachers
Analysis of difficulties of junior high school students in solving AKM numeration problems
Get PDFExploration of the difficulties faced by students in facing AKM exams is a challenge for teachers and practitioners of mathematics education. The main objective of this study is to map information about the difficulties students experience in carrying out AKM exams so that they can be used as evaluation material to prepare for better mathematics learning in the future. The selection of subjects was carried out randomly by considering good communication so that the data obtained could represent the population. Semi-structured interviews are used in collecting research data in order to create a more humane and conducive atmosphere. Data analysis used codes that had been reduced from the interview transcripts. The results of the research show that there are various challenges that need to get the attention of both teachers, students and parents of students. The loss of students' motivation in learning mathematics needs to get very serious attention for teachers and parents
Ethnomathematical exploration of the “Ompangan” tradition of the Jember Madura community
Get PDFCulture is closely related to the lives of Indonesian people, in the current era of technological sophistication, culture is one of the means to study science, one of which is ethnomathematics. Ethnomathematics is a branch of mathematics that uses culture as a means to deepen the knowledge and concepts of mathematics education through the role of culture in society. This study focuses on the ethnomathematical exploration of the “ompangan” tradition of the Jember Madura community in Kalisat with the aim of describing ethnomathematics in the ompangan tradition of the community and formulating the concept of mathematical calculations. This research took place at Jalan Diponegoro Dusun Krajan 1 RT/RW 012/004 Glagahwero Kalisat. This study uses a qualitative method with a descriptive approach, with data collection techniques through interviews and observations. The results showed that the ompangan culture contained mathematical concepts in it that linked culture to the mathematical counting process, namely the concept of worth comparison and a system of linear equations used to determine the number of goods with the same price or value
