Abstract – Stable matching is one of the topics in graph theory, as an application of weighted bipartite graph.On completion of the process of stable matching is used an algorithm is called Gale-Shapley algorithm. To find the stable matching in research, to analyzed stable matching in any weighted bipartite graph with and , any weighted complete bipartite graph with and , as well as also example of the application of stable matching using Gale-Shapley algorithm. Research purposes to determine stable matching in weighted bipartite graph using Gale-Shapley algoritm. The results of this research is using step by step Gale-Shapley algoritm untill get stable matching. Stable matching is only obtained on arbitrary any weighted bipartite graph with and any weighted complete bipartite graph with . In any weighted bipartite graph with and any weighted complete bipartite graph with , obtained maximum matching. Stable matching which has element of a set of large, can be solved with a program Python 3.5.1. Keywords – Matching, Graph, Gale-Shapley Algorithm

Abstract – Image segmentation is the process of separating the object from the background or of other objects that are not a concern, so the object can be processed for the other purposes. Along with the development of technology in digital image processing application, the segmentation process becomes increasingly necessary. The results of the segmentation must be accurate so that any error does not happen in the interpretation of information from an image. This article discussed the application of the minimum spanning tree on a graph in a segment of an image. This method is able to separate an object from the background so that it produces binary image, which is in this case, the object that being the focus is set in white, while the background is black or otherwise. The whole processes were done by using the Matlab R2013a. Keywords – graph, minimum spanning tree, image segmentation, digital image

Pencarian Clique Maksimal dan Bilangan Clique pada Graf Sederhana Menggunakan Modifikasi Algoritma Clique Shintia Pratiwi; Armiati Armiati; Dewi Murni

Abstract – Finding maximal clique is a problem to get a clique with the maximum number of points on a graph, where the selected points are the points that are connected to each other. Finding maximal clique in a graph would be easier if using an algorithm. One of algorithms that can be used to determine the maximal clique is clique algorithm. However, the clique algorithm still has a weakness that the process is a relatively long process because it has two procedures. Therefore, in this study a modification to this algorithm. An algorithm not only must be correct, but also must be efficient. The efficiency of an algorithm is measured from the execution time of the algorithm and the space of memory that is required to run it. After modification is done to clique algoritma, the time of complexity asymptotic algorithm gained is .

The Covid-19 pandemic is sweeping the entire world, including Indonesia, which has resulted in changes to the education system. Face-to-face learning system turns into online learning. Teachers are asked to be creative in using online learning media to achieve learning objectives, one of which is YouTube. This study aimed to analyze the use of YouTube as a medium for learning mathematics during the Covid-19 period. This research is a descriptive study through observation and interviews with teachers and students. The research instrument used student observation sheets, teacher observation sheets, and interview guides. The study results were obtained through descriptive analysis and show that YouTube has significant benefits as a medium for learning mathematics and as the best information seeker during the Covid-19 pandemic.
