Abstract

At present, research on Ramsey Numbers has expanded to a wider scope, not only between 2 complete graphs that are complementary to each other but also a combination of complete graphs, circle graphs, star graphs, wheel graphs, and others. While the classic Ramsey number still leaves problems that need to be solved. Ramsey number R(3,4) > 8. This means that m=8 is the largest integer such that K_(8) which contains components of a red graph G and a complete blue graph G which is still possible not to get K_3 in graph G and not get a blue K_4 in graph G .The graph K_(8) has a total of 28 edges. There are as many as the combination (28,3) red edge pairs that need to be avoided so as not to get any red K_3 edge pairs. And there are as many as the combination (28,4) edge pairs blue. That needs to be avoided in order not to get a pair of blue K_4 edges. Determining the coloring of the of the graph directly is certainly very difficult, especially if the Ramsey number is getting bigger. It's like looking for a needle in a haystack. Need to use a special method in order to solve this problem. The weighting graph method, where each edge is given weight with a certain value, is able to solve this problem. The weighting graph method is able to display the graph K_8 in the form of a G matrix with the order of 8×8.

Abstract

Research is motivated by the low problem-solving ability of students in learning mathematics. The purpose of this study was to determine the validity, effectiveness and practicality of interactive learning media based on problem based learning integrated self-confidence to improve students' problem-solving skills. The subject of this research is class XI SMA Negeri 5 Padang. The method in this research is the development research method with the ADDIE development model. The data collection instrument used was a validation questionnaire given to the validator to determine the validity of the product, and a questionnaire response from educators and students to determine the practicality of the product, as well as test instruments in the form of pretest and posttest to determine the effectiveness of the product. The results of the analysis of the data obtained were declared very valid with an average score of 90,7%. The results of the practicality test of teacher responses stated that the interactive learning media developed was very practical to be used with an average score of 100%, while the practicality test of students was declared practical with an average score of 85%. The results of the effectiveness test were obtained from the N-Gain of 0.48 with the medium category. This proves that problem based learning-based interactive learning media that integrate self-confidence to improve students' problem-solving skills is worthy of being used as a learning resource.

Abstract

This research is motivated by integrated thematic learning in grade IV SDN 29  South Coastal District, this study aims to determine the improvement of the integrated thematic learning process for theme 9 using the CIRC model for class IV SDN 29 Pesisir Selatan Regency.  This research is a classroom action research (PTK) which consists of four stages, namely planning, implementation, observation, and reflection. This research was carried out in two cycles consisting of three meetings.  This study uses a qualitative and quantitative approach, the subject of this research is the fourth grade educators and students at SDN 29 Pesisir Selatan Regency with a total of twelve students.  The results showed an increase in student learning outcomes in class IV, this increase can be seen from the learning implementation planning (RPP) cycle I was 65% and cycle II 72.5%.  implementation of learning on the aspect of educators in the first cycle is 67.15% and 75% in the second cycle.  the implementation of learning on the aspects of students in the first cycle is 67.15% and the second cycle is 75%, the learning outcomes of students in the first cycle are 56% and the second cycle is 91.66%. thus it can be concluded that the CIRC model in class IV at  elementary school in south coastal regency can improve student learning outcomes.while the results and conclusions in the form of simple present tense.

Abstract

Penelitian ini mengevaluasi aplikasi Augmented Reality (AR) dalam pendidikan matematika dan dampaknya. Dengan metode studi literatur, peneliti menyelidiki penerapan AR dalam pembelajaran matematika. Hasil menunjukkan AR memperkaya pengalaman belajar dengan meningkatkan keterlibatan siswa dan pemahaman, terutama dalam visualisasi konsep kompleks seperti geometri ruang dan grafik fungsi. AR juga meningkatkan motivasi siswa dan hasil belajar. Kemampuan AR mengonversi konsep abstrak menjadi visualisasi 3D memudahkan siswa memahami materi dari perspektif berbeda. AR juga mendukung siswa dengan kesulitan belajar, dengan menyajikan visualisasi yang memudahkan pemahaman konsep. Namun, terdapat tantangan dalam menerapkan AR, seperti kebutuhan sumber daya, pelatihan guru, dan integrasi ke kurikulum yang ada. Solusinya melibatkan pelatihan intensif bagi guru, peningkatan infrastruktur teknologi, dan riset lebih lanjut untuk materi AR khusus matematika. Sebagai kesimpulan, AR menawarkan potensi besar dalam pendidikan matematika, tetapi diperlukan kolaborasi antara peneliti, pendidik, dan praktisi untuk integrasi yang optimal.
