Abstract

Penelitian kualitatif ini dilakukan untuk mengetahui gambaran dari kemampuan mahasiswa dalam membuktikan suatu pernyataan matematika pada mahasiswa yang memprogramkan matakuliah analisis variabel riil. Kemampuan pembuktian langsung menjadi kemampuan yang harus dimiliki mahasiswa untuk lulus pada matakuliah analisis variabel riil. Mahasiswa diberikan instrumen berupa soal pembuktian matematis dengan beberapa alternatif jawaban pembuktian. Jawaban mahasiswa direduksi dengan mengelompokkan jawaban pembuktian langsung yang sejenis. Selanjutnya dipilih mahasiswa untuk diwawancarai berdasarkan perwakilan masing-masing kelompok jawaban tersebut. Hasil penelitian menunjukkan bahwa masih terdapat mahasiswa yang tidak mengetahui langkah awal atau pernyataan awal yang digunakan untuk menyusun argumen pembuktian langsung. Namun, ada pula mahasiswa yang sudah dapat menyusun argumen pembuktian dengan baik dan disertai penjelasan untuk setiap argumen yang dituliskan. Hasil penelitian ini juga berguna sebagai bahan refleksi bagi penulis khususnya dalam proses pembelajaran pada matakuliah analisis variable riil.

Abstract

Kemampuan melakukan operasi perkalian merupakan keterampilan dasar yang penting dalam pembelajaran matematika di tingkat Sekolah Menengah Pertama (SMP). Namun, siswa sering mengalami kesulitan dalam menyelesaikan perkalian dua dan tiga digit, khususnya pada metode bersusun panjang. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman serta motivasi belajar siswa melalui pelatihan metode lattice multiplication. Kegiatan dilaksanakan di SMP Negeri 1 Insana dengan melibatkan 23 siswa kelas VII. Metode pelaksanaan menggunakan desain pre–post deskriptif dengan instrumen berupa tes dan angket skala Likert. Hasil menunjukkan rata-rata nilai siswa meningkat dari 1,26 menjadi 4,39. Selain itu, hasil angket menunjukkan peningkatan minat, motivasi, persepsi kemudahan, dan kepercayaan diri siswa setelah pelatihan. Temuan ini menunjukkan bahwa metode lattice multiplication efektif sebagai alternatif pembelajaran perkalian yang visual dan menyenangkan. Temuan ini menunjukkan bahwa metode lattice multiplication dapat menjadi strategi pembelajaran visual yang efektif dalam membantu siswa memahami operasi perkalian serta berpotensi mendukung penguatan kemampuan numerasi siswa di tingkat sekolah menengah pertama

Abstract

The purpose of this study is to identify fraudsters using Symmetric Bivariate Polynomials with one share detecion. This type of research is quantitative using the method Secret Sharing Scheme (SPR). Where in this study combines several schemes, one of which is Scheme Liu et al. (2018). The scheme Liu et al. (2018) is a Symmetric Bivariate Polynomial scheme, in the writing of the Liu et al. (2018) scheme they identy fraudsters using two share detections. In the study, researchers also use Symmetric Bivariate Polynomials to identify fraudsters, so that the results are obtained, namely at the secret shering stage using Symmetric Bivariate Polynomials, at the reconstruction stage using Lagrange interpolation and using Symmetric Bivariate Polynimials with one share detection where is a random integer. Thus it can be concluded that the identification of fraudsters using Symmetric Bivariate Polynimoials is able to identify fraudsters and by using one share detection is faster in the computation process.

Abstract

The research aims to analyze vector content material and produce teaching materials that are valid, practical, and effective. The research method used is Alessi and Trollip's development research, which consists of three stages: planning, design, and development. The results of this research indicate that the vector space materials developed for teaching include vectors in R2, R3, and Rn, line and plane parameter equations, dot products and cross products, as well as line and plane coordinate equations in R3. The module assessment from two material experts was 3.33, indicating it is very feasible, while from two media experts it was 3.9625, also indicating it is very feasible. The benefits of this product in supporting students' understanding of vector space material include the composition of the material being based on an in-depth analysis of the textbooks used, relevant sources, and student test results from the previous three years. This approach helps students comprehend vector space, as the module presents relevant images to support the explanations. Additionally, the material in the module is integrated with Prezi, which helps to capture students' interest and encourages them to focus on the explanations. In conclusion, the developed teaching materials are effective in enhancing students' understanding of vector space concepts and are highly feasible for use in educational settings.

Abstract

Mathematics is used in various aspects of life, including the maritime and marine world. Mathematical concepts are widely used to solve problems in this field. Understanding abstract mathematical concepts requires a tool to bridge these concepts into concrete forms. The aim of this study is to determine the effect of using the Android version of GeoGebra software in improving the mathematical abilities of cadets. GeoGebra is a comprehensive and easy-to-use mathematical software. A study conducted on cadets at Politeknik Ilmu Pelayaran Makassar found that the use of the GeoGebra application had a positive impact on their understanding of mathematical material. This was demonstrated by inferential statistics tests and supported by the cadets' responses to the application's use in learning.

Abstract

This research is motivated by the lack of worksheets development (LKS) at school based on the Realistic Mathematics Approach (RMA), which has resulted in low student mathematical abilities, especially in solving system of linear equations in two variables. This research aims to produce valid, practical, and effective Student Worksheets (LKS) based on the Realistic Mathematics Approach (RMA) for algebra. The research aimed to improve students' mathematical abilities, which will impact student learning outcomes. The research type is research and development (R&D) using the 4-D model. The target population of this study was 20 students of class VIIIA at Junior High School Neonbat. The instruments used were expert validation sheets, student response questionnaire sheets, and pretest and posttest questions. The results of the study showed that the quality of the student worksheets met the validity criteria, with an average value of 84.78% in the very valid category. The results of the LKS practicality questionnaire showed an average score of 90.6% in the very practical category. While in terms of effectiveness, it met the effective criteria. The average individual score for the pretest results was 24.5. However, it increased after using the student worksheet as indicated by the posttest results with an average value of 79.5. The percentage of classical completion based on the posttest results was 80%, which is included in the effective category. So that, the student worksheet for algebra material through realistic mathematics approach met the criteria of valid, practical, and effective.

Abstract

Abstrak Pemahaman konsep matematika terlihat dari cara berpikir siswa dalam menyelesaikan masalah matematika. Mulai dari cara menuliskan langkah-langkah penyelesaian, jawaban akhir, sampai kepada mendapatkan alternatif penyelesaian masalah. Penelitian ini dilakukan di SMP Negeri 1 Malaka Timur dan bertujuan untuk menganalisis sejauh mana pemahaman konsep matematika yang diklasifikasikan dari level berpikirnya berdasarkan taksonomi SOLO. Pengambilan data dilakukan dengan memberikan tes pemahaman konsep pada 18 siswa Kelas VII kemudian dilakukan reduksi data dan dipilih 5 responden yang mewakili masing-masing level berpikir. Hasil penelitian menunjukkan subjek 1 memiliki level berpikir prastruktural dan tidak memenuhi indikator pemahaman konsep, subjek 2 memiliki level berpikir unistruktural dan memenuhi salah satu indikator pemahaman konsep, subjek 3 memiliki level berpikir multistruktural dan memenuhi dua indicator pemahaman konsep, subjek 4 memiliki level berpikir relasional dan memenuhi semua indikator pemahaman konsep dan subjek 5 merupakan level berpikir extended abstract dan memenuhi semua indicator pemahaman konsep. Kata kunci: level berpikir, pemahaman konsep matematika, taksonomi SOLO
