Abstract

This script was aimed to determine the necessary conditions for boundedness of Riesz potential in the classical Morrey space. If these results are combined with previous research results will be obtained the necessary and sufficient condition for boundedness of Riesz potential. This necessary condition is obtained through the use of characteristic function as one member of the classical Morrey space.

Abstract

This study aims to determine the value of metric dimensions and local metric dimensions of relative prime graphs formed from modulo  integer rings, namely . As a vertex set is  and  if  and  are relatively prime. By finding the pattern elements of resolving set and local resolving set, it can be shown the value of the metric dimension and the local metric dimension of graphs  are  and  respectively, where  is the number of vertices groups that formed multiple 2,3, … ,  and  is the cardinality of set . This research can be developed by determining the value of the fractional metric dimension, local fractional metric dimension and studying the advanced properties of graphs related to their forming rings.Key Words : metric dimension; modulo ; relative prime graph; resolving set; rings.

Abstract

Misalkan diberikan sistem linear atas ring komutatif. Beberapa sifat penting dari sistem linear adalah stabil asimtotis, terkendali, dan terobservasi. Sistem dikatakan stabil asimtotis jika solusi sistem dalam rentang waktu tak terbatas akan menuju ke suatu titik tertentu, dalam hal ini titik kesetimbangan. Selain menggunakan kriteria nilai eigen, kestabilan sistem linear berkaitan erat dengan eksistensi solusi persamaan Lyapunov. Tujuan penelitian ini adalah menentukan syarat cukup eksistensi solusi persamaan Lyapunov pada sistem linear waktu diskrit atas ring komutatif terkait kestabilan, keterkendalian, dan keterobservasian sistem.

Abstract

Let  G be a connected graph with vertex set V(G) and W={w1, w2, ..., wm} ⊆ V(G). A representation of a vertex v âˆˆ V(G) with respect to W is an ordered m-tuple r(v|W)=(d(v,w1),d(v,w2),...,d(v,wm)) where d(v,w) is the distance between vertices v and w. The set W is called a resolving set for G if every vertex of G has a distinct representation with respect to W. A resolving set containing a minimum number of vertices is called a basis for G. The metric dimension of G, denoted by dim (G), is the number of vertices in a basis of G. In general, the comb product and the corona product are non-commutative operations in a graph. However, these operations can be commutative with respect to the metric dimension for some graphs with certain conditions. In this paper, we determine the metric dimension of the generalized comb and corona products of graphs and the necessary and sufficient  conditions of the graphs in order for the comb and corona products to be commutative operations with respect to the metric dimension.

Abstract

This community service activity aims to improve students’ understanding and skills in calculating especially the basic calculation operations, namely addition, subtraction, multiplication, and division. Calculating skills for elementary school students is very important as students prepare to understand mathematics material in general or in solving simple problems in everyday life. The target of this activity is elementary school students in grade 2 and grade 3, because when students are in grade 3 elementary school, this numeracy ability must be mastered by students. With the provision of materials using application software, students seem enthusiastic and enthusiastic in participating in the material and practice working on questions. This activity was carried out on Thursday, November 9, 2017 at Nogosari 03 SD Rambipuji Elementary School, Jember, attended by 80 students.AbstrakKegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan pemahaman dan keterampilan siswa dalam berhitung khususnya terhadap operasi hitung dasar, yaitu penjumlahan, pengurangan, perkalian, dan pembagian. Keterampilan berhitung bagi siswa sekolah dasar sangatlah penting sebagai bekal siswa memahami materi matematika secara umum maupun dalam menyelesaikan permasalahan sederhana dalam kehidupan sehari-hari. Sasaran kegiatan ini adalah siswa sekolah dasar kelas 2 dan kelas 3, sebab saat siswa berada di kelas 3 sekolah dasar, kemampuan berhitung ini harus dikuasai oleh siswa. Dengan pemberian materi menggunakan software aplikasi, siswa tampak antusias dan semangat dalam mengikuti materi maupun latihan mengerjakan soal. Kegiatan ini terlaksana pada hari Kamis, 9 November 2017 bertempat di SD Negeri Nogosari 03 Rambipuji, Jember, diikuti oleh 80 siswa.

Abstract

Tujuan utama dari pengabdian kepada masyarakat ini adalah untuk meningkatkkan kemampuan matematika siswa SMPN 7 Surabaya, khususnya dan siswa Indonesia pada umumnya melalui pembentukan klinik matematika.  Jika klinik matematika di SMPN 7 Surabaya berhasil dilakukan, maka prototype klinik ini dapat dijadikan contoh untuk pembentukan klinik untuk pelajaran lainnya dan di sekolah lainnya.Metode pendekatan pengmas adalah (1) workshop pembentukan dan penyusunan administerasi klinik matematika, (2) workshop media pembelajaran, (3)  workshop pendampingan pembuatan observasi kemampuan siswa, (4) workshop penyusunan butir soal dan analisis butir soal.  Target dari kegiatan Pengmas adalah terbentuknya Klinik Matematika di SMPN 7 Surabaya dengan semua kelengkapannya.  Di samping itu diharapkan klinik ini dapat digunakan oleh guru dan kepala sebagai sarana untuk melakukan penelitian, baik penelitian tindakan kelas (PTK) atau penelitian tindakan sekolah (PTS). Hasil pengmas adalah adalah (1) terbentuknya klnik matematika dengan rincian tupoksi dan SOP klinik, (2) media pembelajaran berbasis thatquiz, (3) User manual media pembelajaran untuk kelas 7 berbasis thatquiz, (4) soal observasi kemampuan berhitung siswa berbasis thatquiz, (5) nilai kemampuan berhitung siswa, (6) hasil analisis butir soal Penilaian Tengah Semester.Kata kunci: klinik matematika, media pembelajaran berbasis thatquiz, user manual.
