Abstract

Let be a ring. Ring is said to be a clean ring if every element of R can be expressed as the sum of a unit and an idempotent element. Furthermore, there are r-clean rings. An r-clean ring is a generalization of a clean ring. In an r-clean ring, all of its elements can be represented as the sum of a regular element and an idempotent element. Moreover, strongly r-clean rings were introduced. A strongly r-clean ring is a ring where every element of the ring can be expressed as the sum of a regular and an idempotent element, and the multiplication of that regular and idempotent is commutative. On the other hand, there is a ring of the set of matrices over ring denotes by . In this paper, we will discuss the cleanness properties, especially strongly r-clean of the subring of . The aims of this paper are to find the characteristics of strongly r-clean of the subring of . Here, we assumed that is a ring of matrix over .

Abstract

Pembelajaran koordinat kartesius merupakan salah satu materi dasar dalam matematika yang diajarkan di sekolah dasar. Pembelajaran koordinat kartesius dapat dilakukan dengan banyak cara. Pengabdian yang kami lakukan, memberikan alternatif pembelajaran mengenai koordinat kartesius. Alternatif pembelajaran tersebut menggabungkan pembelajaran koordinat kartesius dengan pixel art. Kegiatan pengabdian masyarakat ini menyasar pada siswa-siswi Kelas 5 SD Muhammadiyah 16 Karangasem, Kota Surakarta. Tujuan dari kegiatan ini yaitu untuk meningkatkan pemahaman dan motivasi siswa dalam pembelajaran koordinat kartesius melalui pendekatan kreatif dengan Pixel Art dan Mystery Cartesian Coordinate Games. Selain itu, siswa juga dapat mengetahui penerapan matematika melalui pixel art. Hasil kegiatan menunjukkan peningkatan minat belajar, kerja sama, dan pemahaman konsep koordinat kartesius, serta menjadikan pembelajaran matematika lebih interaktif dan menyenangkan.
