Consider a finite graph G that is simple, undirected, and connected. Let W be an ordered set of vertices with |W| = k. The representation of a vertex v is defined as an ordered k-tuple that consists of the distances from vertex v to each vertex in W. The set W is called a resolving set for G if the k-tuples for any two vertices in G are distinct. The metric dimension of G, denoted by dim(G), is the smallest possible size of such a set W. In this paper, we determine the metric dimension of edge comb product of trees with complete multipartites or petersen graphs.

This study investigates high school students’ visual-spatial thinking ability in the context of transformation geometry using a descriptive quantitative design. A total of 241 students from public and Islamic high schools in Jakarta participated in the study, responding to a validated 40-item multiple-choice test assessing four key indicators: imagining, problem-solving, pattern seeking, and conceptualising. Results reveal that students generally performed at a medium level across all indicators, with the highest scores in imagining (M=62.97) and the lowest in conceptualising (M=47.05). These findings suggest that while students demonstrate some spatial reasoning capability, their conceptual understanding remains limited. The study highlights the importance of incorporating visualisation-focused strategies in geometry instruction to strengthen spatial reasoning and deeper comprehension of transformation concepts. Future research should explore the longitudinal impact of visual-spatial training and its role in developing higher-order geometrical thinking.

The Ministry of Higher Education's Regulation No. 3, 2020, issued the MBKM curriculum as a foundation for learning development at the University. Since 2021, the mathematics education study program at UIN Syarif Hidayatullah Jakarta has been carrying out off-campus activities to support the MKBM curriculum. After 4 years of MBKM activities, the study program needs to survey to determine the effectiveness and usefulness of implementing the MBKM program. The purpose of this study is to describe the MBKM program and to find out the undergraduate students’ responses related to this. The research method is qualitative research with a survey method. The population was 288 undergraduate students in the mathematics study program, and the sample was 150. The instrument is a questionnaire to determine the effectiveness of the socialization of the MBKM program, the extent of understanding and perception of the MBKM curriculum, and its implementation. The results showed: 1) 27% of undergraduate students got information from the study program, 2) 78% of undergraduate students understood about the MBKM curriculum, and 3) more than 50% of undergraduate students agreed that outside-campus activities can improve teaching skills, mathematical content, and technology mastery. It was concluded that MBKM activities outside-campus positively impacted undergraduate students and need to continue. Recommendation: study programs need to conduct intense socialization about MBKM, and continue the outside-campus program, to train undergraduate students' pedagogical skills, content knowledge, and technology skills.

This research aims to develop a mathematics e-module using CBL based on Augmented Reality (AR) with Jakarta Ethnomathematics nuances that is valid, able to facilitate students' mathematical critical thinking skills, and get very good responses. The method used was the development method (R&D) with the Plomp model. The Plomp model consists of 3 phases, which are preliminary research, prototype phase, and assessment phase. The results showed that in the preliminary research phase, the results of curriculum analysis, learner needs analysis, and task analysis were obtained so that a solution to improve critical thinking skills could be formulated. In the prototyping phase, an e-module was produced which had an average level of percentage score of material and media validity of 93.44% and 92.31% with “Very Valid” criteria. The posttest results showed that the e-module was able to facilitate students' critical thinking skills seen from the achievement of average completeness which was more than KKTP and classical proportion completeness of more than 75%. Mathematics e-modules using AR-based CBL with Jakarta Ethnomathematics nuances received a “Very Good” response from students of 96.63%. In conclusion, mathematics e-modules using AR-based CBL with Jakarta Ethnomathematics nuances are proven to be categorized as very valid, able to facilitate students' mathematical critical thinking skills, and this module is easy to use in the learning activity.

The advancement of software technology has led to the emergence of various mobile-based application development platforms such as App Inventor, Android Studio, Xamarin, Thunkable, Flutter, and SDK. However, their potential as media for mathematics learning remains underexplored. This study aims to develop an Android-based mobile learning application using Flutter for teaching algebra in junior high schools. The research employed a Research and Development (R&D) approach, adopting the MOAM (Metodología para Desarrollar Objetos de Aprendizaje Móviles) model, which includes five stages: analysis, design, development, assessment, and publication. Data were collected through observations and interviews, followed by media trials involving 32 seventh-grade students from a selected junior high school in South Tangerang during the 2023–2024 academic year. Expert validation was conducted by mathematics education lecturers from UIN Syarif Hidayatullah Jakarta and junior high school mathematics teachers. The results showed high feasibility, with media and material assessments scoring 95% and 90%, respectively. Feedback from teachers and students also indicated strong approval, with ratings of 96% and 93%. The developed application is considered suitable for supporting algebra learning in junior high schools.
