Abstract

The purpose of this study in general is to determine the ability of students of SMP Sunan Giri Malang in understanding mathematical concepts. The specific objectives in this study, including: 1). Describing students' ability in understanding concepts on opportunity material, 2) Describing students' abilities in understanding concepts when solving problems. This research belongs to the type of qualitative descriptive research. Qualitative descriptive research was used to analyze the ability of eighth grade students of SMP Sunan Giri Malang in understanding the concept of opportunity. Data was collected through the methods of observation, tests, interviews and documentation. Furthermore, the data were analyzed descriptively qualitatively sequentially based on the question indicators, as follows; 1) Restate a concept, 2). Giving examples and not examples of a concept, 3). Presenting concepts in various forms of mathematical representation, 4). Grouping objects according to the properties, 5). Apply a concept or algorithm to problem solving. The results showed that the ability of class VIII students of SMP Sunan Giri Malang on the overall opportunity material got the following percentages: high ability category 47%, medium ability category 35% and low ability category 23%.

Abstract

The development of LKS can help teaching and learning activities in the classroom especially during the covid-19 pandemic. Worksheets that are made in an attractive and systematic manner can help students to learn to be more active in learning mathematics. Choice of approach and model Learning is also something that plays a very important role in supporting development Interesting and systematic worksheets. The purpose of this study was to determine the feasibility of developing LKS with a scientific approach on the number material for class VII MTs Muhammadiyah 1 Malang. This research was a development research using the ADDIE development model which consists of five main stages, namely Analysis, Design, Development, Implementation, and Evaluation. The LKS developed was validated by three validators, namely two mathematics education lecturers and a seventh grade mathematics teacher. The quality of the LKS with a scientific approach that was developed was assessed from the aspects of media, language and material with an average validation result of 83.12%. The subject of the experiment was carried out on class VII A students of MTs Muhammadiyah 1 Malang with a total of 23 students. Data collection techniques were carried out by interviews, validation, tests and questionnaires. Based on the results of the small group trial, an average percentage score of 80.45% showed that the LKS was very valid, in the large group the LKS that the researchers developed got a very interesting response with an average percentage score of 81.13%. So that the LKS compiled with a scientific approach is feasible to use.

Abstract

Land administration increasingly relies on mathematical, statistical, geometric, and computational methods, yet the literature treats these approaches in isolation and rarely examines their roles or the conditions under which they work. This study aims to map how mathematical approaches are used and discussed across land science and to identify the conditions that shape their effectiveness, with a focus on Indonesia. A systematic literature review followed PRISMA 2020. We searched Scopus, Web of Science, Google Scholar, and the SINTA and Garuda portals in January–February 2026, retrieving 784 records. After deduplication, independent double screening (Cohen’s κ = 0.81), full-text assessment, and quality appraisal with an adapted CASP checklist, 15 peer-reviewed studies published in 2009–2025 were selected by criterion-based purposive sampling and analyzed through thematic synthesis. Mathematics served structural (formal data modeling, n = 4), analytical (measurement, valuation, and survey analysis, n = 5), and contextual (evidence on institutional, regulatory, and adoption conditions, n = 6) roles. Quantified gains were reported mainly in valuation, for example, a root mean square error of 0.526 for an AHP-based model against 1.953 for multiple regression and time and resource savings of up to 80% for a neural-network model, whereas evidence on tenure and institutional outcomes was uneven. The review contributes a role-based framework and a conditional-effectiveness reading of the evidence. It implies that Indonesian cadastral digitalization should prioritize data quality, model interpretability, and practitioner competence.
