Abstract

Let G be a connected and simple graph with vertex set V(G) and edge set E(G). For a graph G, we define k-labeling such that the edges of G are labeled with integers {1,2,3,....,k_e} and the vertices of G are labeled with even integers {0,2,4,....,2k_v}, where k=max{k_e, 2k_v}. If there is a different weight for all edges, then the labeling is called edge irregular reflexive k-labeling. The weight of edge xy, notated by wt(xy) is defined as a sum of label of x, label of xy, and label of y. The minimum k for which G has an edge irregular reflexive k-labeling is defined as reflexive edge strength of G, symbolized by res(G). In this research, we determined the reflexive edge strength of several Cartesian graphs, namely P_5xP_n, S_4xP_n, C_5xC_n, and F_3xP_n. Keywords: Edge irregular reflexive k-labeling, reflexive edge strength, Cartesian graph.

Abstract

This research is to find out students' mathematical thinking processes in visual audio learning with the help of student worksheets based on numeracy literacy on coordinate material. with a qualitative-descriptive subject of 30 grade 7 students at a junior high school in Jember. The research instrument is a matter of description and student results sheets are concluded from learning. The aim is to know the process of thinking mathematically in students. Descriptive data analysis based on the results of the LKPD sheet answers. Given math questions whose answers do not only use numbers, but also with descriptive sentences that are explained correctly and according to theory. the use of audio-visual learning media, students understand more about the direct example material presented in the learning video. The video also presents examples or benefits of coordinates that are usually used in everyday life, for example in airplane flights
