Analysis of Civil Engineering Students' Mathematical Thinking Skills in Calculus Based on Personality Type
Mathematical thinking skills are crucial competencies for civil engineering students in dealing with increasingly complex infrastructure problems, one of the foundations of which is laid by basic calculus. However, students show varying abilities, indicating the influence of internal factors such as personality. This study aims to describe the relationship between students' personality types, as measured by the Myers–Briggs Type Indicator (MBTI) framework, and the mathematical thinking abilities of civil engineering students in calculus learning. This study uses a descriptive qualitative approach involving civil engineering students at Samudra University. Personality types were determined using the MBTI questionnaire, while mathematical thinking skills were measured by analyzing students' written answers to calculus problems compiled based on mathematical thinking indicators. Data were analyzed descriptively and qualitatively to identify patterns in mathematical thinking skills across personality types. The results of the study indicate that students with ESFJ or SFJ tendencies tend to show strength in applying concrete procedures (specializing), while students with ENFJ or NFJ tendencies tend to demonstrate greater flexibility in developing intuitive ideas. This study suggests that students' personalities should be taken into account when designing calculus learning. The application of adaptive and differentiated learning strategies tailored to individual personality characteristics may be considered.

Analisis Kesalahan Siswa dalam Menyelesaikan Soal SPLDV Ditinjau dari Kemampuan Pemecahan Masalah Matematis
This study aims to determine the types of errors students make when solving SLETV word problems. The method used is a qualitative literature study. The novelty of this research lies in the use of the Integrative Findings Synthesis Framework to examine images of students' answer sheets in depth. The analytical approach used is Polya's problem-solving stages, which are linked to basic algebraic error models. The results show a chain of errors across Polya's stages. Students who misunderstand the problem at the beginning will automatically make mistakes when creating equation models, make errors when calculating, and tend not to re-check their final answers. These results are useful for teachers in designing more appropriate classroom teaching methods.

Analisis Kemampuan Pemecahan Masalah Matematis Siswa Berdasarkan Prosedur Polya ditinjau dari Self-efficacy pada Materi SPLTV
Mathematical problem-solving ability is not only related to the mastery of concepts and procedures but is also influenced by affective factors such as self-efficacy. This study aims to analyze students’ mathematical problem-solving abilities in the topic of Three-Variable Linear Equation System based on Polya’s procedures in terms of self-efficacy. This type of research is descriptive research with a qualitative approach. The study was conducted at a public senior high school in Bogor Regency involving 30 eleventh-grade students, with three students selected as the main subjects based on high, moderate, and low self-efficacy categories. Data were collected through a self-efficacy questionnaire and a mathematical problem-solving ability test based on Polya’s four-step procedures. The findings revealed that students with high self-efficacy were able to carry out all problem-solving procedures systematically and consistently. Students with moderate self-efficacy demonstrated fairly good ability but were not yet consistent, particularly lacking thoroughness in understanding the problem and still making errors at the evaluation stage. Meanwhile, students with low self-efficacy tended to experience difficulties in solving problems, characterized by a lack of problem understanding, inaccuracies in constructing mathematical models, and failure to evaluate the final results. These findings confirm that the higher a student’s self-efficacy, the better their problem-solving ability.

Mathematical connection profile of low-achieving students in pythagorean theorem problems
Mathematical connection ability is a fundamental competency that Indonesian students have not yet developed optimally, as evidenced by persistently low performance on both national and international assessments. This condition warrants in-depth qualitative investigation, particularly among low-achieving students whose specific connection difficulties remain poorly understood. This qualitative descriptive study was conducted at SMA Negeri 3 Semarang. A total of 72 tenth-grade students completed a preliminary written test measuring three NCTM mathematical connection indicators. Based on the results, ten students fulfilling at most one indicator were selected through purposive sampling as interview subjects. Data from semi-structured interviews were analyzed using the Miles and Huberman model. Results revealed nine subjects fulfilled only Indicator 1, one fulfilled only Indicator 2, and none fulfilled Indicator 3. Interview exploration revealed distinct thinking processes across all three indicators and three qualitative patterns of connection difficulty comprising weak prerequisite mastery, inability to link concepts that were individually understood, and inability to complete problem-solving despite having a sense of the solution path. These findings highlight the importance of diagnostic and instructional approaches tailored to the specific nature of each student's difficulty.

Kemampuan Pemecahan Masalah Matematika Siswa SMP dalam Menyelesaikan Soal HOTS ditinjau dari Tahapan Polya
This study aims to describe the mathematical problem-solving profile of junior high school students when solving Higher Order Thinking Skills (HOTS) problems based on Polya's stages. Employing a qualitative descriptive approach, this research involved 15 seventh-grade students from a high-performing public junior high school in Sleman Regency, Yogyakarta. The research instrument was an algebraic problem-solving test validated through expert judgment. The subjects were categorized into high, moderate, and low mathematical ability groups. Three students from each category were then selected for in-depth analysis using investigator triangulation. The results indicated that the high-category students successfully carried out all of Polya's stages, including implicit reviewing, as evidenced by procedural precision and accurate final answers. The moderate-category students were able to understand the problems but encountered errors during the execution stage and neglected to evaluate their results. Meanwhile, the low-category students experienced cognitive obstacles right from the problem-understanding stage and demonstrated no metacognitive activities. This study concludes that students' failure in solving HOTS problems is primarily caused by weak metacognitive control and an insufficient mastery of algebraic concepts. Consequently, mathematical instruction must habituate reflective strategies at every stage of the problem-solving process.

Pengaruh Model Pembelajaran Kontekstual Terhadap Hasil Belajar Peserta didik Kelas VIII SMPN 22 Mataram Tahun Pelajaran 2025/2026
Contextual learning is directly related to real phenomena. This motivates students to learn more actively, encourages them to think critically, and makes the knowledge learned more meaningful and easy to apply in everyday life. In fact, in learning, students only see, hear and write materials so that learning outcomes are low. This study aims to empirically test the effect of the contextual learning model on the learning outcomes of class VIII students of SMPN 22 Mataram in the 2025/2026 Academic Year. The subjects in this study were class VIII students at SMPN 22 Mataram who were distributed into 2 groups of 43 people, each VIII A with 21 people and VIII B with 22 people. Data collection was carried out using learning outcome tests and student and teacher observation guidelines. The data analysis technique used was the independent sample t test (polled variance). The results of the analysis showed that there was a significant influence of the contextual learning model on the learning outcomes of class VIII students of SMPN 22 Mataram in the 2025/2026 Academic Year. This is indicated by a statistically significant average difference between the two groups with a t-test value of 6.875 > t table 1.681 significance of 0.000 < 0.05. The category of contextual learning influences learning outcomes very significantly with an effect size of 5.74 > 0.8. The results of this study are expected to not only be a theoretical study, but can be implemented in real terms as an applicable solution in overcoming problems in mathematics learning.

Visualisasi Bibliometrik Pendekatan Matematis dalam Studi Hukum waris Islam dan Implikasinya terhadap Pendidikan Matematika
The integration of mathematical approaches into Islamic inheritance law (faraid) plays a crucial role in ensuring accuracy, fairness, and consistency in the distribution of inheritance; however, a systematic mapping of related research remains limited. This study aims to analyze publication trends, conceptual structures, and thematic dynamics of research adopting mathematical approaches in Islamic inheritance law during 2015–2025. A descriptive bibliometric approach was employed, utilizing selected publication metadata retrieved from Google Scholar via the Publish or Perish software and visualized using VOSviewer. The results indicate a gradual increase in publications over the last decade, although mathematical approaches have not yet become a dominant research paradigm. The conceptual structure of the literature is still largely shaped by normative and applicative orientations, with mathematics primarily functioning as a supporting instrument rather than a standalone analytical framework. Network, overlay, and density visualizations further reveal that mathematical integration is a relatively recent and developing trend, characterized by a gradual shift toward more quantitative and interdisciplinary perspectives. These findings highlight opportunities for future research to strengthen mathematics as a more substantive analytical foundation in Islamic inheritance law and to support its integration into context-based mathematics education.

Analisis Komparatif Kesalahan Kognitif dan Penalaran Matematis Siswa pada Soal PISA Level 6
This research is motivated by the crucial issue of declining Indonesian PISA scores in 2022, which raises the urgency to evaluate and understand the disparity in mathematical literacy skills across educational levels. The purpose of this study is to comparatively analyze the cognitive error profiles and mathematical reasoning of junior high and senior high school students in Makassar in solving mathematical literacy problems equivalent to PISA Level 6. This study uses a qualitative descriptive method through a comparative case study design. The research subjects consisted of ninth-grade students from two public junior high schools and tenth-grade students from one public senior high school in Makassar City. Data were collected using a written essay test instrument that adapted the PISA 2022 framework for the content of Quantity, Uncertainty and Data, and Change and Relationships. The written data were then analyzed using a modified Newman Error Analysis procedure. The results highlight significant ability disparities and several cognitive problems: (1) at the junior high school level, students tend to stall and make literal errors at the comprehension and transformation stages; (2) At the high school level, although there is progress in average conceptual understanding, students experience stagnation in critical data literacy evaluation competencies. This finding leads to the conclusion that the pattern of students' written errors indicates the fossilization of misconceptions, where errors in mathematical understanding are not corrected and continue to be carried over from elementary to secondary education.

Predictor variables included the number of fatalities, the number of minor injuries, the time of the accident, the type of accident, the cause of the accident, the road status, the road condition, and the road type. The analysis was conducted using binary logistic regression with a stepwise variable selection method based on the Akaike Information Criterion (AIC). The results showed that the number of fatalities, the number of minor injuries, the time of the accident, the type of accident, the road status, and the road type significantly influenced traffic accident severity. The resulting model achieved a classification accuracy of 78.11%, enabling a reasonably good classification of accident severity.

Model Regresi Quasi Poisson Jumlah Korban Kecelakaan Lalu Lintas di Kabupaten Lamongan
Traffic accidents are one of the major transportation safety problems that may cause casualties and material losses. Analysis of the number of accident victims is important to describe accident severity and identify influencing factors. This study aims to model the number of traffic accident victims in Lamongan Regency based on time characteristics and road conditions using Quasi Poisson regression. The data used were secondary data obtained from the Lamongan Police consisting of 1,202 traffic accident observations during 2025. The analysis stages included descriptive analysis, Poisson regression modeling, dispersion testing, and Quasi-Poisson regression modeling. The dispersion test result showed a dispersion parameter value of 0.4161, indicating underdispersion where the variance was smaller than the mean. This condition caused the standard Poisson regression model to be less appropriate because the equidispersion assumption was not fulfilled. The Quasi Poisson model produced more reliable statistical inference by adjusting the variance through a dispersion parameter. The significant variables affecting the number of traffic accident victims were month, day category, road status, and road condition. Therefore, the Quasi Poisson regression model was more suitable for modeling underdispersed traffic accident count data.

This condition emphasizes the importance of needs analysis as a foundation for developing relevant learning media. This study aims to analyze and identify the needs for interactive learning media in statistics for eighth-grade junior high school students. This research is a descriptive study employing a qualitative approach. The subjects consisted of two mathematics teachers and eight students from eighth-grade selected purposively with heterogeneous academic abilities. Data collection was conducted through semi-structured interviews. The data were analyzed using the Miles, Huberman, and Saldaña model, encompassing data reduction, data display, and conclusion drawing. The findings concluded that teachers and students require interactive learning media with specific characteristics to address students' learning difficulties in understanding statistical concepts. The identified media needs were categorized into three main aspects, including gradually structured content presentation accompanied by real-world examples and dynamic visualizations using images or animations; two-way interactivity through quizzes or games coupled with practice exercises featuring immediate feedback; and visually appealing yet simple design with flexible accessibility via smartphones. Therefore, the development of interactive learning media with such characteristics is highly necessary to support more effective, interactive, and meaningful statistics learning for eighth-grade junior high school students.

Analisis Kemampuan Representasi Matematis Siswa dalam Menyelesaikan Soal Matematika Materi SPLDV
This study aims to analyze how junior high school students express their ideas when solving problems related to the System of Linear Equations in Two Variables (SPLDV). Mathematical Representation Ability is essentially a "bridge" for students to transform difficult and abstract mathematical concepts into more real and simple forms, whether through images, symbolic formulas, or written explanations. SLETV was chosen due to its characteristics that involve complex word problems, requiring students to be proficient in converting long narratives into correct mathematical models. Through a literature review method analyzing various previous research findings, it was found that students' representation abilities are heavily influenced by their basic mathematical proficiency levels. High-achieving students are generally proficient in using symbols and graphs, yet they still face challenges in providing narrative explanations for their reasoning. Meanwhile, low-achieving students and slow learners show significant obstacles in initiating problem-solving, thus requiring specific assistance or scaffolding.

Klasifikasi Kegagalan Pengobatan Penyakit Tuberkulosis (TB) di Kota Mataram Menggunakan Metode Multivariate Adaptive Regression Splines (MARS)
Tuberculosis (TB) is an infectious disease that affects the lungs and can spread through the air. Indonesia ranks second globally, contributing approximately 10% of the total TB cases worldwide. The Province of Nusa Tenggara Barat (NTB) has been recorded as having a high number of TB cases, with the City of Mataram being one of the areas with the highest incidence. Although TB can be cured through anti-tuberculosis drug (OAT) treatment for six months, the success rate of this treatment has declined since 2016. Several factors such as age, gender, education level, and other health conditions may influence treatment success. Therefore, evaluating treatment outcomes is very important, including monitoring the results of treatment to determine whether the treatment is successful or unsuccessful. In order to classify TB treatment failure, an effective statistical method that can be used is Multivariate Adaptive Regression Splines (MARS). MARS is a flexible nonparametric regression method capable of handling high-dimensional data, making it very useful for classifying data with many predictor variables. This study aims to classify TB treatment failure in the City of Mataram using the MARS method, with the expectation of improving treatment success in the region. Based on the analysis using the MARS method, the type of TB (X₅) was found to be the main determining variable of treatment outcomes, with a fairly good overall classification accuracy of 80%.

Studi Kasus Dinamika Kognitif pada Proses Abstraksi dan Klasifikasi dalam Membangun Pemahaman Konseptual Geometri
This research is motivated by the low spatial literacy among elementary school students, who tend to memorize physical features of shapes without understanding their hierarchical logical relationships. The primary objective is to deconstruct the cognitive dynamics in building geometric conceptual understanding through the integration of abstraction and classification processes. Adopting a descriptive qualitative case study design, the study included 5th-grade students selected via purposive sampling. Data were collected using the Conceptual Geometry Task instrument through the Think-Aloud Protocol (TAP) technique, observations, and task-based interviews, which were then qualitatively analyzed using data triangulation. Specific findings indicate that the subjects reached a mature stage of abstraction by extracting invariant attributes to perform hierarchical classification consistent with Van Hiele Level 1. Furthermore, a progressive self-correction mechanism was identified as a means of overcoming high cognitive load by modifying logical strategies. Contextually, this study indicates that students’ procedural errors are often integral to the process of developing conceptual abstraction. The practical implications emphasize the urgency for educators to validate students' learning trajectories to foster comprehensive mathematical reasoning.

Penerapan Logika Fuzzy Metode Mamdani dalam Memprediksi Hasil Produksi Beras di Indonesia Tahun (2024)
Rice production is one of the main indicators of national food security, especially in Indonesia. Accurate rice production forecasts are essential to support strategic planning and decision-making in the agricultural sector. This study aims to apply fuzzy logic using the Mamdani method to forecast rice production in 2024. This method was chosen for its ability to handle the uncertainty and complexity of data that often occurs in agricultural systems. The variables used include harvest area, productivity, rainfall, and average temperature. The data analyzed is historical data from several previous years, which is then processed using a fuzzy inference system. The prediction process was carried out in several stages, namely fuzzification, rule formation, inference, and defuzzification. The results of the study indicate that the Mamdani fuzzy logic model predicts rice production in 2024 to be 27,100,000 tons; it is hoped that this model will provide predictions that closely align with historical data and trends, with a relatively small margin of error. Thus, this method can be a reliable and adaptive tool in supporting future rice production planning and policy.

Model Konflik Kognitif Konseptual Berbasis Visualisasi Dinamis (Model KKVD) untuk Meningkatkan Pemahaman Konseptual Transformasi Geometri
This study develops and examines the initial effectiveness of the Conceptual Cognitive Conflict Model Based on Dynamic Visualization (KKVD Model) for improving students’ conceptual understanding of geometric transformations. Initial effectiveness is defined here as the model’s capacity to produce statistically and practically significant differences in learning outcomes during a small-scale field trial, prior to broader dissemination. Using a Research and Development (R&D) design adapted from Thiagarajan’s 4D model (limited to the Develop phase), followed by a quasi-experimental field trial, the KKVD Model was validated by three experts (mean score 87.7%, Very Valid). The experimental group (n = 20) and control group (n = 20) consisted of Grade XI students from SMK Widyagama Malang, selected through purposive sampling based on comparable prior achievement and class availability. The experimental group’s mean posttest score (81.46) significantly exceeded the control group (72.29), with N-Gain of 0.70 (high) versus 0.54 (medium), and a large effect size (Cohen’s d = 1.12; p < 0.001). The most substantial improvements occurred in the conceptual relations and generalization dimensions, reflecting deeper conceptual restructuring. The KKVD Model systematically integrates cognitive conflict, GeoGebra-based dynamic visualization, and conceptual reconstruction into a validated instructional syntax, offering a promising alternative for meaningful geometry transformation learning.

High School Students’ Mathematical Problem-Solving Abilities: A Polya-Based Analysis
This study aims to analyze high school students' mathematical problem-solving abilities in exponential and logarithmic functions based on Polya's four stages of problem solving. This study employed a qualitative descriptive approach involving 72 tenth-grade students from a senior high school in Samarinda. Data were obtained through essay tests designed to reveal students' problem-solving processes and semi-structured interviews to strengthen the interpretation of students' work results. Data analysis was conducted through the stages of data reduction, data presentation, and conclusion drawing. The results showed that students' problem-solving abilities varied across ability categories. High-ability students tended to plan, execute, and review the entire problem-solving process, although they did not always write down the initial information explicitly. Students with moderate abilities showed an initial understanding of the problem but had difficulty devising and carrying out a plan, which led to inadequately verified final results. Meanwhile, students with low abilities experienced obstacles from the problem comprehension stage, which led to failure in the subsequent stages. These findings emphasize the importance of strengthening conceptual understanding and practicing systematic problem-solving steps in mathematics learning.

Kemampuan Metakognisi Siswa Berdasarkan Gaya Belajar Dalam Pemecahan Masalah Matematika
Mathematical problem-solving ability is one of the essential competencies that students must possess in solving non-routine mathematical problems, as it requires higher-order thinking skills. Metacognitive ability plays an important role in students' mathematical problem-solving processes. However, each student has different metacognitive abilities, one of which is influenced by their learning style characteristics. This study employed a descriptive qualitative approach and aimed to investigate students' metacognitive abilities based on the learning styles of MTs students in solving non-routine mathematical problems. The research was conducted as a descriptive qualitative study. The research subjects were selected based on auditory, visual, and kinesthetic learning style categories. Data were collected through non-routine mathematical problem-solving tests, learning style questionnaires, and interviews to reveal students' metacognitive thinking processes. Data analysis was carried out by referring to the stages of metacognition, namely Awareness, Regulation, and Evaluation. The results showed that students' metacognitive abilities differed at each metacognitive stage across the three learning styles. Visual learners demonstrated more comprehensive metacognitive abilities, while auditory and kinesthetic learners still experienced difficulties, particularly at the evaluation stage. Nevertheless, all three subjects were able to obtain correct final solutions to the problems. These findings indicate that learning styles influence the characteristics of students' metacognitive processes in solving non-routine mathematical problems.

Analysis of Abstraction and Algorithmic Thinking Skills in Solving Realistic Mathematics Problems: Students versus Artificial Intelligence
Artificial Intelligence (AI) in education not only offers significant potential for facilitating access to information but also presents challenges to students’ independence and thinking processes. Problem-solving is a fundamental cognitive skill that requires abstraction and algorithmic thinking. Preliminary analysis revealed that 22 out of 25 students experienced difficulties in identifying relevant information and designing algorithms to solve realistic mathematical problems. These students made errors in simplifying problems and formulating strategic solution steps despite using AI. This qualitative study aims to describe the errors made by students in the processes of abstraction and algorithmic thinking. In addition, students’ solutions were compared with AI-generated outputs to identify their error characteristics. The study involved three students and two AI models (ChatGPT and Gemini) as subjects. Data were collected through realistic problem-solving tests and interviews. The findings indicate that students remain vulnerable to both conceptual and procedural errors, whereas AI predominantly exhibits conceptual errors in the abstraction process. These findings highlight the need to enhance students’ abstraction and algorithmic thinking skills through more effective instructional approaches. Although AI has the potential to support simulation and analysis, it cannot fully replace students’ thinking abilities; therefore, students’ confidence in solving problems should also be strengthened

Narrating Pedagogical Identity: Mathematics Lecturer Generation Z in the Digital Teaching Era
This study explores the pedagogical identity becoming of Generation Z mathematics lecturers within digital learning contexts. Using a qualitative narrative inquiry design, the study involved two Gen Z mathematics lecturers from Indonesian universities. Data were collected through in-depth interviews and analyzed through narrative storytelling and interpretive thematic analysis. The findings reveal that pedagogical identity develops through a dynamic, non-linear process of becoming shaped by reflection, adaptation, and the negotiation of pedagogical experiences. Technology functions not merely as an instructional tool but as a pedagogical space that shapes teaching practices, relational interactions, and professional meaning-making. The lecturers continuously negotiate closeness, authority, and emotional relationships within digitally mediated classrooms. The study proposes a conceptual model that shows how pedagogical identity emerges from the interconnected experiences of personal history, pedagogical practice, socio-emotional relations, and digital pedagogical spaces.

This study aimed to develop an ethnomathematics-based interactive learning media that meets the criteria of validity and practicality. The study employed a Research and Development (R&D) approach using the Four-D (4D) development model, consisting of the define, design, develop, and disseminate stages. However, the research was limited to the develop stage, which involved validation by media experts and subject matter experts, as well as practicality assessment by practitioners. The research instruments included media expert validation sheets, material expert validation sheets, and practitioner response questionnaires. The data were analyzed quantitatively using descriptive statistics in the form of mean scores and feasibility percentages. The findings indicate that the developed ethnomathematics-based interactive learning media achieved valid criteria based on expert evaluations and practical criteria based on practitioners' assessments. Therefore, the developed media can serve as an alternative mathematics learning resource to support students' conceptual understanding.

Perbandingan Kinerja Metode Naïve Bayes, SVM, dan ANN dalam Klasifikasi Status Gizi Balita
Masalah gizi pada balita merupakan tantangan kesehatan masyarakat yang krusial. Peningkatan kasus kekurangan dan kelebihan gizi pada balita memerlukan pengolahan data untuk proses klasifikasi sehingga dapat memberikan kemudahan dalam mengambil kesimpulan dan mengambil tindakan dalam pencegahan kekurangan dan kelebihan gizi balita. Oleh karena itu, penelitian ini menggunakan tiga metode yaitu Naïve Bayes, SVM, dan ANN untuk mengetahui kinerja dalam mengklasifikasikan status gizi balita menggunakan platform Google Colab dengan tahapan pengumpulan data, prepocessing data, pemodelan data, dan evaluasi performa berupa confusion matrix yang berfungsi untuk mengukur kinerja model klasifikasi machine learning. confusion matrix berisi metrik evaluasi lanjutan untuk menilai kualitas model secara spesifik yaitu accuracy, precision, dan recall. Hasil penelitian menunjukkan metode ANN dengan tingkat akurasi 99% merupakan metode terbaik dan paling efektif dalam pemantauan gizi balita dibandingkan SVM tingkat akurasi sebesar 98%, dan Naïve Bayes sebesar 93%. Hal ini juga didukung adanya keunggulan ANN dalam menyesuaikan bobot secara iteratif melalui hidden layers sehingga mampu memodelkan hubungan non-variabel antara variabel berat badan dan tinggi badan secara presisi.
