Abstract

Abstrak: Untuk mewujudkan visi Indonesia menjadi Indonesia emas tahun 2045, maka penting bagi dunia pendidikan melakukan perubahan pola pikir. Guru memiliki peran yang sangat strategis bagi dunia pendidikan. Tantangan pendidikan berkualitas, mengharuskan guru untuk lebih kreatif, inovatif, dan inspiratif. Permasalahan yang ada pada sekolah mitra berdasarkan wawancara yang telah dilakukan kepada kepala sekolah serta guru yang ada di KKG 01 kecamatan Panti yaitu pendidik mengeluhkan akan rendahnya kemampuan literasi dan numerasi siswa. Peran dari seorang guru sangat penting untuk menjembatani cara berfikir siswa SD khususnya untuk memahami hal yang abstrak. Berdasarkan fakta di lapangan, tuntutan tersebut tidaklah selaras dengan kuantitas pendampingan pengembangan kompetensi guru, dimana forum untuk pengembangan kompetensi pedagogic dan professional seorang guru masih sangatlah minim.  Salah satu inovasi model pembelajaran yang memotivasi siswa dan membermaknakan matematika adalah pembelajaran matematika menggunakan Mathtrail. Mathtrail merupakan aktifitas pembelajaran luar ruangan yang mengikuti sebuah rute yang telah dibuat dan siswa menyelesaikan masalah-masalah yang terdapat pada titik-titik pemberhentian yang ada.Kegiatan pengabdian dengan sasaran pendidik di Kecamatan panti Kabupaten Jember, dikemas dengan menerapkan model pelatihan ADDIE (Analysis-Design-Development-Implementation-Evaluation). Berdasarkan hasil pre test dan post test pembelajaran berbasis math trail, rata-rata N-Gain keseluruhan adalah 0,59. Oleh karena pembelajaran berbasis math trail dapat dinterpretasikan Cukup Efektif karena dapat meningkatkan hasil tes yang menjadi tolak ukur mengingkatnya kemampuan penalaran matematis siswa. Dampak dilakukannya pengabdian adalah siswa lebih mudah memahami konsep matematika yang abstrak dengan melakukan pengamatan secara langsung. Pembelajaran menggunakan mathtrail juga membantu meningkatkan literasi dan numerasi siswa.Abstract: In order to realize Indonesia's vision of becoming a golden Indonesia in 2045, it is important for the education to change its mindset. Teachers have a very strategic role for the development of education. The challenge of quality education requires teachers to be more creative, innovative and inspiring. Based on interviews with school principals and teachers in KKG 01 Panti sub-district, the problems that exist in partner schools are that educators complain about the low literacy and numeracy abilities of students. The role of a teacher is very important to bridge the way of thinking of elementary school students, especially to understand abstract things. Based on the facts on the ground, these demands are not in line with the quantity of teacher competency development assistance, where the forum for the development of a teacher's pedagogic and professional competencies is still very minimal. One of the innovative learning models that motivates students and gives meaning to mathematics is learning mathematics using Mathtrail. Mathtrail is an outdoor learning activity that follows a route that has been made and students solve problems found at existing stopping points. Community service activities with the aim of educators in the Panti District of Jember Regency, are packaged by applying the ADDIE (Analysis-Design) training model. -Development-Implementation-Evaluation). Based on the results of the pre test and post test based on math trail learning, the overall average N-Gain is 0.59. Because math trail-based learning can be interpreted as quite effective because it can improve test results which are a benchmark for increasing students' mathematical reasoning abilities. The impact of doing community service is that it is easier for students to understand abstract mathematical concepts by making direct observations. Learning using mathtrail also helps improve student literacy and numeracy,

Abstract

Coloring graph is giving a color to a set of vertices and a set of edges on a graph. The condition for coloring a graph is that each color is different for each neighboring member graph. Coloring graph can be done by mapping a different color to each vertex or edge. Rainbow coloring is a type of rainbow connected with coloring edge. It ensures that every graph G has a rainbow path. A rainbow path is a path in a graph where no two vertices have the same color. The minimum number of colors in a rainbow connected graph is called the rainbow connection number denoted by rc(G). The graphs used in this study are the Amal(Fn,xz,m) graph and the Amal(On,xz,m) graph.

Abstract

The aim of this research is to analyze the big data literacy skills that a prospective mathematics educator needs to master. Specifically, the ability to read, analyze, make conclusions, and think based on data and information, especially large amounts of data, so that mathematics education students have a broad mindset, and can carry out new innovations. Kemmis and McTaggart's Classroom Action research model was used as the research method. Its stages have four, namely planning, action, observation, and reflection. The planning and action stages took the form of preparing and validating case method-based learning tools in the Operations Research course and were implemented in 3 classes. Lectures are divided into 3 stages: problem-based learning, case method learning from the business world, and case-based learning (Case Method). During the learning process, observation and reflection are carried out. Learning involving the business world, namely Astra Financial and an expert in data sciences, provides opportunities for students to process company big data. The data literacy ability indicators used are the ability to group data, check data, clean data, do qualitative coding, eliminate data, and develop models. The learning results show that students have carried out all big data processing steps in the very good category (> 80%), except for the developing model phase (65.38%). Mini research field studies at partner institutions for the application of operations research in the community. Learning completeness reached 83.11%, and learning activeness reached 82.14% in the very active category. Learning results show an increase in the Big Data Literacy skills of prospective educators and lecturers, even though mastery of big data processing software still needs to be improved.

Abstract

The local antimagic total vertex labeling of graph G is a labeling that every vertices and edges label by natural number from 1 to such that every two adjacent vertices has different weights, where is The sum of a vertex label and the labels of all edges that incident to the vertex. If the labeling start the smallest label from the vertex then the edge so that kind of coloring is called the local super antimagic total vertex labeling. That local super antimagic total vertex labeling induces vertex coloring of graph G where for vertex v, the weight w(v) is the color of v. The minimum number of colors that obtained by coloring that induces by local super antimagic total vertex labeling of G called the chromatic number of local super antimagic total vertex coloring of G, denoted by χlsat(G). In this paper, we consider the chromatic number of local super antimagic total vertex coloring of Generalized Petersen Graph P(n,k) for k=1, 2.

Abstract

Graph labeling can be implemented in solving problems for various fields of life. One of the application of graph labelling is in security system. Information security is needed to reduce risk, data manipulation, and unauthorized destruction or destruction of information. Cryptographic algorithms that can be used to build security systems, one of the cryptographic algorithms is Hill Cipher. Hill chipper is a cryptographic algorithm that uses a matrix as a key to perform encryption, decryption, and modulo arithmetic. This study discusses the use of Super (3n+5,2)- edge antimagic total labeling to construct the Hill Chiper algorithm. The variation of the edge weight function and the corresponding edge label on the graph, will make the constructed lock more complicated to hack
