Abstract

Learning mathematics is intended so that students are able to use reasoning in identifying, analyzing and concluding a pattern and character of a mathematical object. In addition, by manipulating mathematics students will be able to generalize a concept, compile evidence or explain mathematical ideas and statements. The purpose of this study is to determine the increase in reasoning ability that occurs after implementing a realistic mathematics learning model. This study refers to a quasi-experimental research procedure with a pretest-posttest approach. The population used in this study were all students of class VIII SMP Negeri 11 Pematangsiantar with the sample being all students of class VIIIB, totaling 21 people. The instrument used in this study was a learning achievement test in the form of multiple choice objective tests with four options totaling 24 questions. The results showed that during the pre-test the average score of students was at 64.45 with a standard deviation of 4.575 and experienced an increase during the post-test with an average of 80.25 and a standard deviation of 6.25. In addition, when viewed from the completeness of learning there is also an increase, namely from 57.14 to 80.95.

Abstract

One of the viruses that cause infectious diseases is the corona virus. Corona viruses can cause more serious diseases such as the Severe Acute Respiratory Syndrome-Corona Virus which was epidemic in 2003, the Middle East Respiratory Syndrome-Corona Virus outbreak in 2012 and the 2019 Coronavirus Disease which was epidemic at the end of 2019. The ordinary linear differential equation is an equation differential in which all derivatives appear in linear form and no coefficients depend on the dependent variable. The coefficient can be a function of the independent variable, in which case the differential equation is a linear differential equation with changing coefficients. Based on the relatively large number of cells that are susceptible to infection (S), over time it will decrease and towards a zero value against high immunity, and people under surveillance and patients in care (E) with time will decrease towards high immunity. Meanwhile, the number of infected cells (I) at one time will reach a highest point, which indicates the maximum number of infected cells and gradually decreases with time towards a high increase in immunity. Because fewer S, E, and I are infected, the amount of virus in the body (R) also decreases.

Abstract

Educational demands on a person's ability in the field of mathematics are not enough just to have the ability to count, but also to have the ability to think logically, systematically and critically in an effort to develop mathematical problem solving abilities. To be able to find a solution to a problem, it is very important for students to be able to dig up information from various sources and various forms of information and interpret it using logical, systematic, and critical mathematical thinking skills, which are then known as mathematical literacy skills. The purpose of this study was to determine the ability of mathematical literacy in management study program students at the Panca Budi Development University in Medan. This research is part of a type of qualitative research with the approach used in this study a descriptive approach with a sample of 30 students who were selected randomly. The instrument used is a test of mathematical literacy skills in basic mathematics courses. The data analysis technique used is descriptive analysis of the data collected. Based on the research results obtained, it can be concluded that the mathematical literacy skills of the management study program students at the Panca Budi Brada Development University are in the sufficient category with the dominant mathematical literacy ability being at a moderate level with a percentage of 43.34%.

Abstract

Suppose a finite simple graph is represented in the incidence matrix B. Each row in matrix B is a sequence of binary numbers with finite length. The Hamming distance of two vertices and of a simple graph G is defined as the number of positions of different digits. The Hamming index of a simple graph is the sum of the Hamming distances for all the different points in the graph. Suppose that each and is a simple graph whose degree is almost uniform. Using the Hamming Index, we obtain a formula for the Hamming Index on a graph in the form of corona multiplication and cartesian multiplication with each of the two graphs being of almost uniform degree.

Abstract

The purpose of this study was to determine the increase in students' mathematical communication skills after being taught using the Aptitude Treatment Interaction (ATI) learning model in the Mathematics Education study program, HKBP Nomensen University Medan Academic Year 2022/2023. The population in this study were all students of Mathematics Education, with a sample consisting of 30 people, namely students who attended lectures evaluating learning outcomes in mathematics. The instrument used is a test item of mathematical communication ability. The results of this study were then tested by analysis of variance to answer the proposed research objectives. The data obtained from the research results show that the data is normally distributed because the results of the calculations when testing the requirements using SPSS, the sig. 0.05 is obtained. The results of the data analysis also show that the analysis model designed is valid so that it can prove that the increase in communication skills is influenced by the learning model. From the results of calculating Multiple Comparisons with the Scheffe test, it can be concluded that learning with the ATI model affects ability improvement at all ability levels, whereas the conventional model only affects high levels.

Abstract

This research was conducted using data obtained from UD Kreasi Lutvi. Meanwhile, based on the results of production optimization processing using Table Simplex and QM For Windows V3, production levels show different levels of production, namely 80,000 large packages, 5,000 medium packages and 400 small packages. When UD Kreasi Lutvi produces according to optimal conditions, the profit that can be obtained under optimal conditions is Rp. 386,600,000, while the profit in factual conditions is Rp. 361,268,000, so the increase in profits is Rp. 25,332,000. This shows that the benefits in factual conditions and optimal conditions are much different, but to increase profits, UD Kreasi Lutvi must produce according to optimal conditions.
