Literatur sistematik : pengintegrasian etnomatematika berbasis augmented reality pada pemahaman konsep bangun ruang
type: item
description: This study aims to analyze the results of a systematic literature review (SLR) concerning the integration of ethnomathematics-based Augmented Reality (AR) in geometry learning, particularly focusing on cube and cuboid concepts. This approach reviews the effectiveness of combining local cultural contexts with digital technology to enhance students’ conceptual understanding of mathematics. Literature was collected using the Publish or Perish tool from Scopus and Sinta databases and evaluated following the PRISMA guidelines to ensure relevance and eligibility. From 200 identified articles, 20 studies met the inclusion criteria and were further analyzed. The findings reveal that AR significantly improves students’ spatial visualization, understanding of volume and surface area, and learning motivation. Meanwhile, ethnomathematics serves as a contextual medium linking mathematical concepts to local culture, making learning more meaningful and character-building. The integration of both approaches fosters interactive, contextual, and culturally relevant learning while introducing the concept of symmetry groups through cultural exploration and digital visualization. The study recommends the development of an AR-ethnomathematics-based learning model that explicitly integrates symmetry group concepts to deepen students’ geometric understanding and strengthen cultural values in mathematics education

Kemampuan Literasi Matematika Siswa dalam Menyelesaikan Soal Matematika Tipe HOTS Berdasarkan Gender
type: item
description: Mathematical literacy is a fundamental cognitive competency that enables students to analyze mathematical situations and communicate their reasoning effectively. Although numerous studies have investigated mathematical literacy, research that specifically examines students’ performance on HOTS-type mathematical tasks from a gender perspective remains scarce. This study aims to describe students’ mathematical literacy skills in solving HOTS problems based on gender differences. Employing a descriptive qualitative design, the study involved 35 students from class XII IPA 1, consisting of 7 males and 28 females. Data were collected through tests and semi-structured interviews, then analyzed using data reduction, data display, and conclusion drawing techniques. The findings indicate that in analyzing-type HOTS items (C4), male students generally met only the communication indicator, with one male student demonstrating mastery of all indicators. Conversely, female students consistently fulfilled all mathematical literacy indicators. A similar pattern emerged in evaluating-type HOTS items (C5), where most male students achieved only the communication indicator, while female students met all indicators. In creating-type HOTS items (C6), both male and female students demonstrated achievement solely on the communication indicator.

Analisis Konsep Matematika dalam Penyusunan Laporan Keuangan Mahasiswa Akuntansi
type: item
description: Financial statements are a fundamental element of accounting and serve as the basis for strategic decision-making, requiring mastery of accounting principles and quantitative skills. This descriptive qualitative study aims to describe the mathematical concepts and their applications in the preparation of financial statements by accounting students. Data were collected through interviews, student grades, and financial statement documents. The results indicate that the essential mathematical concepts include basic arithmetic, algebraic equations (e.g., ), ratios/percentages, basic statistics, and rounding. Although all students employed the same concepts, the depth and level of integration varied. Students categorized as “very good” demonstrated the ability to link calculations with transaction reasoning, analyze ratios across periods, apply statistical tools for diagnosis, and maintain accuracy control, resulting in financial reports that are meaningful and actionable. In contrast, students in the “fair” category tended to be procedural, focusing on numerical accuracy but lacking interpretation of the underlying meaning. It is therefore recommended that mathematics instructors develop learning models that integrate mathematical theory with direct accounting practice. Project-based or real case study approaches can help students better understand the relationship between mathematical computation and the actual outcomes of financial reporting.

Meta-Analysis Meta-Analysis of the Effect of RME on Students’ Critical Thinking Skills
type: item
description: This study aims to conduct a meta-analysis of studies evaluating the impact of the Realistic Mathematics Education (RME) approach on enhancing students' critical thinking skills. Using a meta-analytic method, this research combines data from 16 studies to calculate effect sizes, test data heterogeneity, and analyze moderator variables. The effect size is calculated using the Hedges' g formula and classified according to Cohen's criteria: small (less than 0.2), medium (0.2–0.5), and large (above 0.8). The findings show that RME has a significant positive impact, with effect sizes ranging from 0.193 to 2.737. The largest impact was found in urban areas (effect size 1.2014) compared to rural areas (effect size 0.5581). At the elementary school level, the effect size was 0.7908, and at the junior high school level, it was 0.8287. The highest effect size was recorded in the 2023–2025 period (1.1487). Based on these results, it is recommended that educators and policymakers adopt the RME approach, considering local context and student characteristics. Further research with a larger dataset will strengthen statistical validity and deepen understanding of RME implementation in various learning contexts.

Pemecahan Masalah Numerasi Siswa di Daerah 3T dalam Rangka Penyelenggaraan Pendidikan Inklusif di SD
type: item
description: This study aims to provide an in-depth overview of the numeracy problem-solving skills of elementary school students in 3T (frontier, outermost, and disadvantaged) regions, particularly in Pangkep Regency, within the framework of inclusive education. The selection of research subjects was based on the results of the Minimum Competency Assessment (AKM), focusing on numeracy, which includes mastery of basic mathematical concepts and their application in real-life situations. Data collection was carried out through numeracy tests and in-depth interviews. The findings reveal that all respondents, both from grade IV and grade V, were categorized as having low numeracy skills. In the number pattern question, only 16% of grade IV students and 35% of grade V students answered correctly. For the number name question, the achievement rate was 58% for grade IV and 25% for grade V. Meanwhile, in the data analysis question, none of the grade IV students answered correctly, and only 30% of grade V students provided the correct answer. These results indicate that students’ numeracy literacy is low, particularly in reading, understanding, and analyzing information. Contributing factors include the lack of practice with context-based problems, limited learning facilities, the continued use of conventional teaching methods, and the socio-economic background of families. Based on these conditions, there is a need for numeracy learning interventions that are contextual, problem-based, and supported by teacher training to improve the numeracy skills of students in 3T areas. The novelty of this research lies in its specific combination of three aspects: problem-solving, numeracy skills, and inclusive education, particularly in 3T regions.

Open-Ended Problems as a Strategy in Mathematics Modules to Enhance Students’ Mathematics Computational Thinking
type: item
description: Computational thinking (CT) is a key competency in 21st-century mathematics education. However, Indonesian students still face challenges in decomposition, abstraction, and algorithmic reasoning due to learning resources dominated by single-solution problems. This study developed and evaluated a mathematics module based on open-ended problems to enhance students’ CT skills in quadratic functions. The research adopted an R&D approach using the ADDIE model, including analysis, design, development, implementation, and evaluation. The process involved needs, curriculum, and learner analyses, followed by expert validation, practicality testing, and effectiveness evaluation. Three experts validated the module, while teachers and students assessed its practicality. Effectiveness was tested using a quasi-experimental pretest–posttest control group design involving 61 high school students. Data were analyzed using descriptive statistics, N-Gain, and inferential tests. Results showed the module was valid, practical, and effective in improving CT skills. The experimental group achieved significantly higher N-Gain (p < 0.05) than the control group, with abstraction and pattern recognition showing the greatest improvement.

Pemodelan Matematika Penentuan Komposisi Gizi Menu Makan Bergizi Gratis untuk Siswa Sekolah Dasar dengan Metode Simpleks
type: item
description: To address the issue of nutritional deficiencies among Indonesian children, the government implemented a Free Nutritious Meals (MBG) program that meets 30% of the Recommended Nutrient Intake (RNI) for one meal with five food combinations determined by the Ministry of Health. Research aims to determine the composition of the five food combinations and produce the minimum cost of MBG by constructing a linear programming mathematical model. The budget rules set by the government, along with the required amount of nutrition, were calculated as constraints in the mathematical model. The model, which minimizes the objective function subject to 11 nutritional constraints and one budget constraint, as well as non-negative sign restrictions, was solved using the Simplex Method. The model solution, obtained through several iterations for each combination, was generated using AtoZmath software. The results show that the cost of each combination meets the budget rules, and the minimum cost is in combination 1. Additionally, to ensure the budget costs in combinations 2-5 comply with the budget rules, fruit is excluded from the composition of these combinations.

Students’ Mathematical Problem-Solving Ability through Problem Based Learning
type: item
description: This study aims to analyze and describe students’ mathematical problem-solving (MPS) ability through the implementation of PBL treatment on the topic of the perimeter of plane figures in fifth-grade elementary students. The research employed a quantitative approach with a pre-experimental design, specifically a one-shot case study. The participants consisted of 21 fifth-grade students selected using a purposive sampling technique. The research instrument was a problem-solving test that had been validated for both validity and reliability. The results indicate that PBL contributes significantly to students’ achievement in problem-solving ability. Based on the one-sample t-test, the significance value obtained was < 0.001, indicating that the proposed hypothesis was accepted at the 0.05 significance level. Furthermore, the students’ mean MPS score was 85.39, with a median of 90 and a skewness value of -1.320, which signifies a left-skewed distribution, meaning that most students achieved high scores. Furthermore, when viewed across the four problem-solving procedures, only the third stage—solving problems according to the determined procedures—had a percentage below 70%. This lower percentage was primarily due to inaccuracies in calculation processes, which affected the final results. Such errors were more likely caused by miscalculations rather than by the selection of inappropriate problem-solving strategies.

Kendala dan Miskonsepsi Kognitif Siswa dalam Menyelesaikan Soal Geometri Berpikir Tingkat Tinggi
type: item
description: This study aims to identify students’ misconceptions in solving Higher Order Thinking Skills (HOTS) geometry problems on plane figures. A descriptive qualitative approach using Cognitive Error Analysis was applied to the written responses of 10 eleventh-grade students in the Mathematics Cambridge Program. The validated instrument consisted of three HOTS essay items. Data were analyzed through error classification, mapping to HOTS levels (C4, C5, C6), and in-depth diagnosis of responses identified as misconceptions. The findings show that students’ main difficulties lie in the Analyzing stage (C4), which subsequently weakens their ability to evaluate and create strategies (C5–C6). Two dominant patterns emerged: misreading non-routine instructions and errors in fundamental geometric concepts, with several cases indicating independent weaknesses at C6. These results highlight the need to strengthen strategic analysis as the foundation for HOTS development. The study is limited by its small sample size and reliance on written data.

Penalaran Proporsional dalam Pendidikan Matematika: Tinjauan Literatur Sistematis (SLR)
type: item
description: This systematic literature review analyzes international evidence on proportional reasoning (PR) in K–12 education and teacher training. We synthesized eight studies and identified four key patterns. Contexts with hands-on activities help students transition from intuitive to formal strategies. Students often succeed with probability ratios, but struggle with visual biases. Example-based practice with self-explanation improves probabilistic reasoning, especially for less prepared students. Finally, diagnostic tools such as construct maps are useful for tracking student progress from "combined unit" to "multiplicative comparison" understanding. Our review recommends designing a clear progression for ratios, rates, and probabilities; teaching anti-bias strategies; embedding routines of example problems; and using construct map-guided assessments. This synthesis provides a clear action lens to improve PR instruction by integrating student cognition, task design, and teacher practices.

Efektivitas Pembelajaran Geometri Berbasis Etnomatematika dengan Pendekatan Problem-Based Learning Berbantuan Perangkat Mobile terhadap Disposisi Matematis
type: item
description: Abstract This article analyses the effectiveness of ethnomathematics-based geometry learning using a Problem-Based Learning (PBL) approach supported by mobile devices on junior high school students’ mathematical disposition. A quantitative approach with a pre-experimental one-group pretest–posttest design was employed in this study. The sample consisted of 30 eighth-grade students selected through a cluster random sampling technique from a public junior high school in Yogyakarta, Indonesia. The instrument used was a mathematical disposition questionnaire comprising 16 validated statements. Data were analysed descriptively and inferentially using the Shapiro–Wilk test, one-sample t-test, and one-population proportion test. The results revealed a significant improvement in students’ mathematical disposition after implementing ethnomathematics-based geometry learning through the PBL approach assisted by mobile devices. The average questionnaire score increased from 48 (poor category) to 59 (good category), with 90% of students achieving or exceeding the good category threshold. These findings indicate that integrating ethnomathematics into problem-solving activities facilitated by mobile technology can foster students’ confidence, persistence, interest, and comfort in discussing and learning mathematics.

Komunikasi Matematis dalam Pembelajaran Matematika Berbasis Permainan Tradisional: Systematic Literature Review pada Budaya Nusantara
type: item
description: Mathematical communication skills are an essential competency in 21st century mathematics learning. Traditional approaches, which are generally abstract and lack context, are often a barrier to their development. This study aims to systematically examine various studies related to mathematical communication in traditional game-based mathematics learning in the cultural context of the archipelago. The method used is Systematic Literature Review (SLR) with PRISMA guidelines, as many as 15 articles published in 2020–2025 obtained from the selection of Google Scholar, ERIC, and Dimensions databases. The results of the study analysis showed that traditional games such as engklek, congklak, and marbles were most often used in learning and were proven to be effective in improving students' mathematical communication both verbally and in writing. This approach also contributes to increased learning motivation, concept understanding, and character building. These findings support the relevance of ethnomathematical approaches that link mathematics to local cultural practices. It was also found that learning mathematics that integrates traditional games not only strengthens academic competence, but also fosters an appreciation of contextual and meaningful local wisdom for Indonesian students.

Dinamika Pemahaman Konseptual Siswa dalam Pembelajaran Matematika Berbantuan Photomath
type: item
description: Conceptual understanding is at the core of meaningful mathematics learning, as it helps students reason about relationships between ideas and apply mathematical principles logically. However, the learning process in the classroom still focuses heavily on procedural aspects, so that students tend to memorize solution steps without understanding their meaning. This study aims to analyze the dynamics of changes in students' conceptual understanding when using photomath in mathematics learning. The approach used is qualitative with an exploratory case study design, involving six 10th grade students at SMA Negeri 2 Dompu who have applied digital technology in learning. Data were obtained through observation, in-depth interviews, field notes, and documentation, then analyzed through data reduction, data presentation, conclusion drawing, and verification. The results showed that the development of students' conceptual understanding occurred through three main phases, namely algorithmic interpretation, conceptual reflection, and mathematical meaning integration. Photomath functions as a cognitive mediator that helps students transition from procedural thinking to a more reflective and deeper conceptual understanding. The effectiveness of this process is greatly influenced by the role of teachers in directing the use of technology to focus on meaning construction. This study confirms that technology-assisted mathematics learning can enrich conceptual understanding if it is designed to be reflective and oriented towards strengthening reasoning

Strategies for Controlling the Spread of Cholera through Vaccination, Education, and Quarantine; Model Analysis and Simulation
type: item
description: Cholera is an infectious disease transmitted through water contaminated with Vibrio cholerae bacteria. This disease remains a public health challenge, especially in areas with poor sanitation. This study developed an SVIQR-B mathematical model to analyze the dynamics of cholera spread, taking into account the effects of quarantine, vaccination, and environmental hygiene education. The analysis was conducted on disease-free and endemic equilibrium points using a local stability approach based on the basic reproduction number (R0). The results showed that when R0 < 1 , the disease would disappear from the population, while R0 > 1 indicated the potential for endemicity. Sensitivity analysis and numerical simulation results indicate that an increase in the transmission rate and a decrease in vaccine effectiveness cause an increase in the value, while an increase in vaccination coverage and the effectiveness of education contribute to a decrease in infection rates. These findings emphasize the importance of implementing integrated medical and educational interventions in efforts to control cholera in a sustainable manner.

Optimalisasi working memory siswa melalui desain worked example berbasis cognitive load theory pada materi SPLDV
type: item
description: Systems of Linear Equations with Two Variables (SPLDV) contain numerous symbols and present high complexity in their solution processes, which can create substantial cognitive demands for middle school students. Instructional design that minimizes irrelevant cognitive load while optimizing schema formation is essential to accommodate the limited capacity of working memory. Cognitive Load Theory (CLT) offers effective strategic alternatives for managing cognitive load during learning, particularly in reducing extraneous cognitive load. One recommended approach is the implementation of worked example strategies. This article focuses on developing a worked example design for SPLDV material based on CLT principles. The research comprises three phases: examining the cognitive load of SPLDV content, reviewing fundamental CLT principles, and constructing instructional design using worked example strategies. The research produces a worked example design featuring structured solution steps that eliminate split attention and redundancy effects, successfully reducing extraneous cognitive load and enhancing working memory effectiveness in learning SPLDV. These findings can serve as a foundation for further design development or empirical validation in broader educational contexts.

Identification of Spatial Autocorrelation in Cases of Complaints About Illegal Online Loans in Indonesia
type: item
description: The development of digital financial services has made it easier for people to access technology-based loans, but this has also been accompanied by an increase in illegal online lending practices, which have generated numerous complaints from consumers in various regions. This situation indicates the potential for uneven distribution of cases across regions. This study aims to identify interregional spatial relationships in data on the number of complaints about illegal online loans across provinces in Indonesia. This study uses data on the number of complaints about illegal online loans from January to June 2025. The analytical methods used include descriptive statistics, the Moran Index to measure global spatial autocorrelation, and the Local Indicator of Spatial Autocorrelation (LISA) to detect local clusters. The results show positive spatial autocorrelation, where provinces with a high number of complaints tend to be close to each other, particularly areas with high levels of urbanization and digital activity such as DKI Jakarta, West Java, Central Java, and Banten. Thus, the distribution of complaints about illegal online loans is not random but is influenced by geographic proximity and regional socioeconomic characteristics.

Concept Image Siswa dalam Materi Barisan dan Deret pada Pembelajaran Berdiferensiasi
type: item
description: This study aims to describe students' concept images on sequences and series in differentiated learning and to examine the concept image gap between students, teachers, and mathematicians. This study used a qualitative approach with a didactic design and a hermeneutic phenomenology method. The research subjects included students, teachers, and mathematicians, who were selected purposively. Data were collected through learning observations, questionnaires, and in-depth interviews, and then analyzed using data reduction, data presentation, and conclusion-drawing techniques. The results showed that students' conceptual images of sequences and series were dominated by intuitive, visual, and procedural understandings. Students were able to recognize real-world patterns and contexts, but tended to rely on repeated addition or multiplication rather than using formal definitions and symbolic formulas. In geometric sequences and series, a concept image conflict was found due to students' difficulty in understanding exponential growth patterns. Although differentiated learning provides space for diverse student learning styles, the results show that this approach does not fully guarantee the formation of a complete formal conceptual understanding. Therefore, strengthening conceptual scaffolding is needed so that students' concept images are more aligned with the correct concept definition. Penelitian ini bertujuan untuk mendeskripsikan concept image siswa pada materi barisan dan deret dalam pembelajaran berdiferensiasi serta mengkaji kesenjangan concept image antara siswa, guru, dan matematikawan.

Evaluating Swarm-Genetics for VRPTW: Robustness Across Seeds and Fleet Efficiency On Solomon Benchmarks
type: item
description: The Vehicle Routing Problem with Time Windows (VRPTW) is a challenging NP-hard problem in logistics optimization. This study evaluates a Swarm-Genetics algorithm, a hybrid method combining Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) with swarm regeneration and adaptive parameter control. The algorithm was tested on 57 Solomon benchmark instances (C, R, RC) under three random seeds to assess robustness. Results show that the algorithm is robust across seeds, producing stable outcomes with minimal variation. It frequently preserves fleet efficiency, often matching the Best Known Solutions (BKS) in vehicle count, particularly for clustered instances. However, routing distances remain less competitive, with average gaps of about 10% for clustered, 12–13% for random, and over 20% for mixed cases. Convergence analysis further indicates rapid early improvements but stagnation in complex distributions. Overall, Swarm-Genetics provides a robust and fleet-efficient framework, though further enhancements are needed to improve distance quality.

Penerapan Pewarnaan Graf pada Pembagian Kamar Asrama Mahasiswi Universitas Mataram dengan Algoritma Welch Powell
type: item
description: Room assignments at the female dormitory of Universitas Mataram are still done manually, often placing students from the same study program and semester in the same room. This condition limits academic diversity, which is essential to foster social interaction and enhance academic performance. This study aims to apply graph coloring theory to address this issue. Each student is represented as a vertex, and connections between students with the same academic background are represented as edges. The Welch Powell algorithm is applied to color the vertices so that no adjacent vertices share the same color, ensuring students with similar academic characteristics are not assigned to the same room. This applied research uses Visual Basic for Applications (VBA) Macro in Microsoft Excel to automate the creation of matrices and implementation of the algorithm. The results show that this approach is effective and efficient in grouping students into rooms while promoting academic heterogeneity. This method is expected to serve as a practical solution for dormitory management in other higher education institutions.

Penerapan Metode Fuzzy Backpropagation Neural Network dalam Peramalan Saham PT. Bank Rakyat Indonesia (Persero) Tbk. (IDX: BBRI)
type: item
description: The Fuzzy Backpropagation Neural Network (FBPNN) is a forecasting approach based on neural networks that applies the backpropagation learning algorithm, where input and output data are expressed in fuzzy membership values. The construction of the FBPNN model consists of three key phases: fuzzification, neural network training, and defuzzification. In the defuzzification stage, the Smallest of Maximum (SOM) technique is used to determine the lowest value among the members with the highest degree of membership. This research employs FBPNN to forecast the weekly closing prices of PT Bank Rakyat Indonesia (Persero) Tbk. (IDX: BBRI). The dataset is divided into 90% for training and 10% for testing. The results indicate that the best network architecture is 20–4–2, producing a Root Mean Square Error (RMSE) of 728,5308 for training data and 178,2089 for testing data. The Mean Absolute Percentage Error (MAPE) reached 10,3620% (classified as good) in training and 3,9189% (classified as very good) in testing. The developed model was then applied to forecast the next five periods, showing a tendency of increasing stock prices

type: item
description: Fuzzy Geographically Weighted Clustering (FGWC) is a method of development of fuzzy clustering by considering geographical elements in the process of regional clustering. This study aims to identify the number and characteristics of optimal clusters formed using the FGWC algorithm with the validity index of the Partition Coefficient Index (PCI). The data analyzed includes HDI indicators for all regencies/cities on the island of Kalimantan in 2024 consisting of the variables Life Expectancy, Length of Schooling, Average School Length, Expenditure per Capita, Open Unemployment Rate, and Percentage of Poor Population. Based on the results of the study, the optimal number of clusters was obtained as many as 2 clusters with a PCI of 0.516. Cluster 1 consists of 18 regencies/cities covering 9 cities and 9 regencies with higher average values of HDI indicator variables, while cluster 2 consists of 38 regencies which are all dominated by inland areas with lower average values of HDI indicator variables.

title: Efektivitas Model Pembelajaran Kooperatif Tipe STAD (Student Team Achievement Division) untuk Meningkatkan Pemahaman Konsep Matematis dan Self-efficacy Peserta Didik Kelas VIII SMP Negeri 2 Tebing Tinggi
description: This study aims to determine the effectiveness of the STAD cooperative learning model in improving mathematical concept understanding and self-efficacy among eighth-grade students at SMP Negeri 2 Tebing Tinggi. Using a Nonequivalent Pretest-Posttest Control Group Design, this study involved class VIII-5 as the experimental group and class VIII-6 as the control group, which were selected randomly. Based on the research conducted using the Mann-Whitney U test, the results showed that there was a difference in the average mathematical concept understanding of students between the experimental class using the STAD learning model and the control class using the direct learning model. This result was based on an Asymp Sig. (2-tailed) value of 0.002 < 0.05 and supported the research hypothesis that the use of the STAD model was effective in improving students' mathematical concept understanding. In terms of student self-efficacy, using the independent t-test, a Sig. (2-tailed) value of 0.650 > 0.05 was obtained, indicating that there was no difference in the average self-efficacy of students between the STAD learning model and the direct learning model.
