Abstract

Abstract Number theory is an important topic in mathematics that has many applications in everyday life.  Mastery of this concept is important for high school students/equivalent so that they are able to understand the application of mathematics more broadly.  For this reason, in-depth study of the application of number theory in life was carried out for high school/equivalent students in Sukabumi Regency, West Java Province.  This activity is part of community service organized by the Mathematics Study Program in collaboration with the Sukabumi Regency Education Office.  The training was conducted at Al Bayan High School with the aim of strengthening students' understanding of number theory.  As part of the evaluation, questionnaires were distributed to participants before and after the training.  Based on the results of the questionnaire, this activity succeeded in increasing students' knowledge regarding the application of number theory in everyday life.  One of the outputs of this activity is a learning video that will be uploaded to the official UNJ Mathematics YouTube account.        Abstrak Teori bilangan merupakan salah satu materi penting dalam matematika yang memiliki banyak aplikasi dalam kehidupan sehari-hari.  Penguasaan konsep ini penting bagi siswa SMA/sederajat agar mampu memahami penerapan matematika secara lebih luas.  Untuk itu, dilakukan pendalaman materi tentang aplikasi teori bilangan dalam kehidupan bagi siswa SMA/sederajat di Kabupaten Sukabumi, Provinsi Jawa Barat.  Kegiatan ini merupakan bagian dari pengabdian pada masyarakat yang diselenggarakan oleh Program Studi Matematika bekerja sama dengan Dinas Pendidikan Kabupaten Sukabumi.  Pelatihan dilaksanakan di SMA Al Bayan dengan tujuan memperkuat pemahaman siswa terhadap teori bilangan.  Sebagai bagian dari evaluasi, disebarkan kuesioner kepada para peserta sebelum dan sesudah pelatihan.  Berdasarkan hasil kuesioner, kegiatan ini berhasil meningkatkan pengetahuan siswa mengenai aplikasi teori bilangan dalam kehidupan sehari-hari.  Salah satu luaran dari kegiatan ini adalah video pembelajaran yang akan diunggah di akun YouTube resmi Matematika UNJ.

Abstract

Abstract Mathematics is a school material that has a large number of lesson hours in the learning curriculum at junior high school/equivalent level. Content and context in mathematics can be developed with various delivery methods. This is because mathematical material can be viewed as concrete or abstract objects. The logic and knowledge built in this lesson can build a creative side in students' thinking. In this article, we discuss how creative mathematics concepts are applied in training for community service activities in Sukabumi Regency, West Java Province. The method applied uses the concept of project and problem based learning. In its implementation, students are given experience on how to solve mathematical problems by provoking and exploring their creative side. The problems given are chosen to be solved independently or in groups. Of the several problems given, some students succeeded in solving the problem and some were not perfect in solving the problem. This happens because students are not used to solving mathematical problems using their creative abilities. Keywords: training, mathematics, creative, junior high school Abstrak Matematika merupakan materi sekolah yang memiliki jumlah jam pelajaran yang banyak dalam kurikulum pembelajaran di tingkat SMP/sederajat. Konten dan konteks dalam matematika dapat dikembangkan dengan berbagai metode penyampaian. Hal ini disebabkan materi matematika yang dapat dipandang sebagai objek kongkrit maupun abstrak. Logika dan pengetahuan yang dibangun dalam pelajaran ini dapat membangun sisi kreatif dalam cara berpikir siswa. Pada tulisan ini dibahas bagaimana konsep matematika kreatif diterapkan dalam suatu pelatihan pada kegiatan pengabdian masyarakat di Kabupaten Sukabumi Propinsi Jawa Barat. Metode yang diterapkan menggunakan konsep pembelajaran berbasis proyek dan masalah. Dalam pelaksanaannya, siswa diberikan pengalaman bagaimana menyelesaikan masalah matematika dengan memancing dan menggali sisi kreatif mereka. Masalah yang diberikan dipilih untuk diselesaikan secara mandiri maupun berkelompok. Dari beberapa masalah yang diberikan, siswa ada yang berhasil memecahkan masalah dan ada yang belum sempurna dalam menyelesaikan masalahnya. Hal ini terjadi dikarenakan siswa belum terbiasa menyelesaikan masalah matematika menggunakan kemampuan kreatifitas mereka. Kata Kunci: pelatihan, matematika, kreatif, smp

Abstract

Based on the iPrice.co.id website, there are five e-commerce sites in Indonesia with the highest number of visitors. This is caused by the competitive strategy implemented by each e-commerce in order to win or maintain competition with consideration of the most attractive strategy for potential customers. The purpose of this study is to determine the best competitive strategy that needs to be implemented by e-commerce using game theory and consumer evaluation of e-commerce and supporting variables using the AHP (Analytical Hierarchy Process) method. The sample of this research is Jakarta citizens who are e-commerce users. The results of the research on the AHP method obtained e-commerce ranking results with the highest priority ranking to the lowest, namely Tokopedia, Shopee, Lazada, Blibli and Bukalapak. The variables that consumers pay attention to when making purchases on e-commerce from the highest priority to the lowest, namely Security, Trust, Free Shipping, Lots of Promos, Price, Product Quality, Payment Methods, Web Appearance, Product Brands and Product Diversity, where the 6 variables with the highest priority are then selected and these variables are used to determine the best competitive strategy using the game theory method. The results from game theory show that for Tokopedia e-commerce it is necessary to use a Product Quality strategy, Flood of Promos, and Trust, for Shopee namely Free Shipping, Lots of Promos and Security, for Lazada namely Product Quality, Free Shipping, Lots of Promos, and Security, for Bukalapak namely Product Quality, Price, Free Shipping, Lots of Promos, Trust, and Security, for Blibli namely Price, Free Shipping, Lots of Promos and Security.
