Abstract

The online learning system is still having problems. As a result of the observations of the USU team, several obstacles were felt not only by the teachers at MIN 2 Serdang Bedagai but also by students and parents. The problems that occur are quite diverse. Starting from limited signal, limited devices suitable for online learning, to the lack of technological knowledge of teachers and students on online applications that support the teaching and learning process. There are various online applications available today, such as Google Classroom, Zoom, Google Meet, Youtube, and others. These various online applications play an important role in helping students and teachers in the distance learning process. The USU team conducted training using the online application Google Classroom and Zoom. Google Classroom and Zoom were chosen because they are easier for the teacher to implement, besides that the two online applications facilitate coordination and communication between teachers and students, so that the material being taught can be discussed more easily, more freely and can be updated more quickly. In this community service, Online Learning training was conducted for the Elementary School / Madrasah Ibtidaiyah Level with Various Online Applications at MIN 2 Serdang Bedagai. This community service has reached the implementation stage of training which begins with the initial survey stage, provision of training modules and also training.

Abstract

Let G = (V,E) be a nontrivial, finite, and connected graph. A function c from E to {1,2,...,k},k ∈ N, can be considered as a rainbow k-coloring if every two vertices x and y in G has an x- y path. Therefore, no two path's edges receive the same color; this condition is called a “rainbow path”. The smallest positive integer k, designated by rc(G), is the G rainbow connection number. Thus, G has a rainbow k-coloring. Meanwhile, the c function is considered as a strong rainbow k-coloring within the condition for every two vertices x and y in G have an x - y rainbow path whose length is the distance between x and y. The smallest positive integer k, such as G, has a strong rainbow k-coloring; such a condition is called a strong rainbow connection number of G, denoted by src(G). In this research, the rainbow connection number and strong rainbow connection number are determined from the graph resulting from the join operation between the ladder graph and the trivial graph, denoted by rc(L_n∨K_1) and src(L_n∨K_1) respectively. So, rc (L_n∨K_1 )= src (L_n∨K_1 )=2,"for" 3≤n≤4 and rc (L_n∨K_1 )=3, while src(L_n∨K_1 )=⌈n/2⌉,"for" n≥5.

Abstract

In everyday life, three-dimensional shapes are ubiquitous, manifesting in structures such as houses, bottles, and vehicles. These shapes, characterized by length, width, and height, represent the application of functions of two variables, particularly within spatial domains. This research employs Python programming to model functions of two variables, specifically focusing on spatial surfaces. Leveraging the Matplotlib module, graphical representations of these functions are generated, while the NumPy module facilitates mathematical analyses, including identifying extremal values, critical points, and tangent lines. Results demonstrate the efficacy of Python in efficiently modeling functions of two variables. Through this approach, readers gain insights into the inherent characteristics and behaviors of such functions within spatial contexts, thereby simplifying mathematical analyses and enhancing comprehension.

Abstract

Graph theory is an advanced subject of mathematics that can be utilized to resolve issues in science. Graph coloring is one of the most well-known problems for determining the color of the map. The map that will be colored here is one of the 21 sub-districts that cover the Medan regency. In order to color the map, a graph model of the map must first be created. The use of a greedy algorithm is one technique to find a graph's minimal color. The dual graph with 21 vertices and 45 edges will be what we extract from the map. Based on the greedy method that has been used, just four colors—blue, green, red, and yellow—are found as the smallest number of colors, with each city that borders another having a distinct color. The Python computer language is used to get the map coloring results using the greedy technique.
