Abstract

This study aims to analyze students' mathematical problem-solving difficulties in terms of learning styles using the GeoGebra-assisted problem-based learning model. This study uses a descriptive qualitative approach. The subjects of the study consisted of 32 eighth-grade students grouped based on learning styles, namely accommodation, divergent, assimilation, and convergent. Data collection techniques were carried out through learning style questionnaires, mathematical problem-solving ability tests, and interviews. Data analysis was carried out through data reduction, data presentation, and drawing conclusions based on difficulty indicators, namely difficulties in facts, concepts, principles, and operations, which were associated with the stages of Polya's problem-solving. Based on the results of the study of 32 students, it was found that students with an accommodation learning style numbered 7 students (21.87%), a divergent learning style numbered 11 students (34.37%), an assimilation learning style numbered 9 students (28.12%), and a convergent learning style numbered 5 students (15.62%). From the results of interviews with students, for the accommodation of learning style, they experienced difficulties in the concept, principle, and operation indicators. Students with a divergent learning approach experience difficulties with indicators of concepts, principles, and operations. Students with an assimilation learning style experience difficulties with indicators of facts, principles, and operations. Students with a convergent learning style experience difficulties with indicators of principles and operations.

Abstract

Line integrals are one of the fundamental concepts in advanced calculus used to determine the accumulation of a quantity along a specific path within a vector field. This concept has various applications in science, particularly in physics and engineering, especially in calculating the work done by a force acting on an object moving along a certain trajectory. This study aims to examine the application of line integrals in vector fields for calculating the work of a force and to analyze the relationship between a particle’s path and the resulting work. The research method employed is a qualitative approach with mathematical analytical study through theoretical review and calculation of line integrals in two-dimensional vector fields. The analysis process involves defining the vector field function representing the force, parameterizing the particle’s path, and evaluating the line integral to obtain the resulting work. The results show that the work done by a force can be determined through the evaluation of a line integral along the path taken by the particle. Furthermore, the analysis of the vector field indicates that the field is conservative, meaning that the work depends only on the initial and final points of the displacement, not on the shape of the path taken. The visualization of the vector field, particle trajectory graphs, and calculation tables helps provide a clearer understanding of the application of line integrals in analyzing work. Therefore, the concept of line integrals in vector fields can be used as an effective mathematical approach to explain the relationship between force and displacement in a physical system.

Abstract

Riset ini bermaksud mengetahui dampak model pembelajaran Discovery Learning terhadap hasil belajar matematika peserta didik. Metode yang diaplikasikan berupa pendekatan kuantitatif dengan disain eksperimen semu tipe nonequivalent control group design. Sampel penelitian mencakup dua kelas VII di SMP Negeri 28 Medan, yaitu kelas VII – E sebagai kelas ekperimen yang mengaplikasikan model pembelajaran discovery learning dan kelas VII – F sebagai kelas kontrol yang menerima pembelajaran secara tradisional. Alat ukur yang digunakan berupa tes pilihan ganda guna menaksir hasil belajar siswa. Data dianalisis memakai uji-t dan perhitungan effect size. Hasil analisis mengilustrasikan bahwa rata-rata poin posttest anak ajar kelas ekperimen senilai 84,13, lebih tinggi dibanding kelas kontrol yang mendapatkan rerata 74,13. Uji-t menciptakan poin t-hitung senilai 6,702, sementara t-tabel pada taraf signifikan kurang dari 5% (0,000 < 0,05) dengan derajat kebebasan 58 adalah 2,001, sehingga diambil simpulan bahwa t-hitung lebih tinggi dari t-tabel. Beracuan pengujian hipotesisnya, hipotesis alternatif (H1) diterima atau poin rerata hasil belajar anak ajar kelas ekperimen lebih besar dibanding dengan kelas kontrol. Perhitungan effect size senilai 1,73 mengilustrasikan bahwa ada efek yang ditimbulkan pada kategori tinggi. Kesimpulannya, model pembelajaran discovery learning menghadirkan dampak yang signifikan terhadap hasil belajar matematika anak didik.

Abstract

Riset ini bergerak dari kurangnya kualitas mengajar guru sehingga kemampuan komunikasi matematis siswa di MTsS Hifzhil Qur’an menjadi rendah. Sehingga perlu dilakukan penelitian yang menerapkan inovasi pembelajaran yaitu scaffolding dan snowball throwing, dan kemudian melihat perbedaan dari kedua pembelajaran ini terhadap peningkatan komunikasi matematis siswa. Penelitian ini merupakan penelitian eksperimen dengan desain post test only control group design. Adapun lokasi penelitian ini yaitu di MTsS Hifzhil Qur’an dengan populasi 126 siswa kelas VII, sedangkan sampel adalah siswa kelas VII 2 dan siswa kelas VII 3. Untuk mengumpulkan data yang dibutuhkan, peneliti menggunakan lembar tes komunikasi matematis siswa. Selanjutnya digunakan independent sample t test untuk menganalisis data tersebut. Hasil analisis data menunjukkan bahwa kemampuan komunikasi matematis siswa yang diajar dengan pembelajaran scaffolding memiliki perbedaan dengan kemampuan komunikasi matematis siswa yang diajar dengan pembelajaran snowball throwing dimana pembelajaran snowball throwing membuat komunikasi matematis siswa lebih meningkat daripada pembelajaran scaffolding. Dengan kata lain, kedua model pembelajaran yang diterapkan, scaffolding dan snowball throwing dapat menjadi alternatif pembelajaran untuk menyesaikan permasalahan terkait kemampuan komunikasi matematis siswa.

Abstract

This study aims to classify areas in Pancur Batu District based on environmental cleanliness levels using the K-Means Clustering method, analyze the characteristics of each cluster based on cleanliness parameters, and develop a web-based mapping system to visualize the clustering results spatially. The study utilized 578 image data analyzed using five parameters, namely visible waste density, drainage condition, percentage of clean roads, percentage of households with trash bins, and waste collection frequency. The results showed that the areas in Pancur Batu District were successfully grouped into three clusters: Cluster 0 (Clean) consisting of 6 villages, Cluster 1 (Dirty) consisting of 12 villages, and Cluster 2 (Very Clean) consisting of 7 villages. The clustering results were then visualized through a web-based mapping system to facilitate users in identifying the distribution of cleanliness levels across the study area. Expert validation conducted by a geography specialist obtained a total score of 42 with an average score of 4.2, which falls into the good category. Therefore, the implementation of the K-Means Clustering method was able to effectively classify areas based on environmental cleanliness levels and provide useful information to support environmental cleanliness management and decision-making processes in Pancur Batu District.
