Abstract

An intuitionistic fuzzy graph G:V,E consist of a couples of node sets V and set of edges E which the sum of degree membership and degree non membership each of nodes and each of edges in closed interval [0,1], the degree membership each of edges is less than or equal with the minimum of degree membership each nodes of incident, and degree non membership each of edges is less than or equal with the maximum degree non membership each nodes of incident. Product fuzzy graph was defined by Dr. V. Ramaswamy and Poornima B. Product fuzzy graph is fuzzy graph, where the degree membership each of edges is less than or equal with product of the between degree of membership each nodes of incident. In this paper we study the definitions of product intuitionistic fuzzy graph, product intuitionistic fuzzy graph complete, further discussion about the complement of product intuitionistic fuzzy graph, join of product intuitionistic fuzzy graph and multiplication of product intuitionistic fuzzy graph and their characteristics.

Abstract

Graf  adalah graf dengan himpunan titik  dan himpunan sisi  dengan  sisi. Pelabelan graceful sisi-ganjil adalah pemetaan bijektif  yang mengakibatkan pemetaan  yang didefinisikan    sehingga diperoleh label titik berbeda. Graf G dikatakan graf graceful sisi-ganjil jika terdapat pelabelan graceful sisi-ganjil pada graf G. Pada Tugas Akhir ini dikaji tentang pelabelan graceful sisi-ganjil pada graf , graf Double Star , graf , graf Roda . Selanjutnya pada Tugas Akhir ini diberikan konstruksi pelabelan graceful sisi-ganjil pada graf Helms , graf  graf Web .Keywords : graceful, graf graceful sisi-ganjil,  pelabelan graceful  sisi-ganjil

Abstract: Let G be a graph with vertex set V(G) and edge set E(G) . Difine on function f of E(G) to {0,1}, for v∈V(G) value f(v) is obtained by two modulo price of amount of edges label than have insident to the vertex v . The function f is called an E -cordial labeling of G if conditions absolute value from difference the number of vertexs having label 0 and the number having label 1 less or equal 1, and absolute value from difference the number of edges having label 0 and the number of edges having label 1 less or equal 1. Graph which admits of E -cordial labeling is E-cordial graph. The mirror graph M(G) is a bipartite graph with a partite sets V1 and V2 and G' be the copy of G with corresponding partite sets V'1 and V'2 . The mirror graph is obtained by joining each vertex of vi∈V2 to its corresponding vertex in v'i∈V2' by an edge. In this paper we study about labeling of mirror graph for cycle graph, path graph, hypercube graph and bipartite complite graph. The mirror graph of cycle graph, path graph, hypercube graph, and bipartite complite graph are E-cordial graphs.

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.
