Abstract

The presented paper introduces an enhanced approach to find the available solution(s) for fractional linear programming problems (FLPP). While the common approach relies on considering the elements at the numerator and denominator to construct tables D1 and D2, followed by finding theirs and the Ze values, the new approach could be used to minimize the tables and decrease the calculation times and complicity.

Abstract

The research comprised multiple simulated tests to determine the relationship between (sample size, distribution parameter value, estimation method, and pollution indivuduales). The experimental findings indicate that the estimator is influenced by sample size, the value of distribution parameter, estimation method, and pollution indivuduales. The results of the mean square error analysis indicate that (robust estimation method) produces the best results with the lowest mean square error, and the best estimation method was (191) of (243) simulation experiments. Additional statistical distributions with additional factors can be performed to demonstrate additional results.

Abstract

In this article, the starting condition was defined using a fuzzy initial value problem (IVP). Additionally, we discussed various methods for solving fuzzy differential equations, including the modified two-step Simpson method and Runge-Kutta of orders (two, three, four, five, and six). For each method, we provided a numerical example and the known convergence rates of the solutions. Then we discussed the comparison of the solutions of all methods, using computer software to offer rough solutions for the Runge Kutta method. And take some application solve by Runge-Kutta in physics and medical

Abstract

Students who have academic difficulties are a sign that something is wrong. These errors can be in the form of conceptual misunderstandings, errors in forgetting the solution procedure, or careless errors. Therefore, the purpose of this study was to determine the cognitive barriers that elementary school students must overcome to understand the concept of speed and discharge. The methodology used in this study was qualitative. A literature search revealed that poor cognitive development of students, who are often at the concrete operational stage, is the main cause of these obstacles. Additional obstacles noted include proportionality challenges, limited abstraction and imagery capacity, and learning strategies that do not help the process of understanding the topic effectively.

Abstract

This research aims to analyze the ability of Unimed FMIPA Mathematics students in solving absolute value inequalities with the help of the Python program. The problem faced is that students often have difficulty solving inequality problems manually. The purpose of this research is to see the effectiveness of using Python in helping to solve absolute value inequalities and how it affects understanding of mathematical concepts. The method used was qualitative research with a sample of 20 fifth semester students of the Mathematics Study Program, FMIPA, Medan State University. Students are given absolute value inequality problems to solve manually and with the help of Python. Data was collected through online tests and questionnaires using Google Form. The research results show that the majority of students feel that using Python is very helpful in solving absolute value inequalities. As many as 95% of students consider Python to be effective in making it easier to solve mathematical problems and increasing understanding of the concept of absolute value.

Abstract

Mathematics is a science that is structured deductively and systematically. Proof in Mathematics is important because it can enable critical thinking logically, and the truth of a hypothesis can be tested. Mathematical induction is a proof method that has 2 steps, namely basis and induction. With advances in technology today, there are many applications that can make this proof easier, such as Python. This research uses quantitative and qualitative approaches to prove the effectiveness of using Python compared to manual proof. The results show that Python not only speeds up work but also minimizes errors that could occur if done manually. With this research we recommend further exploitation of mathematical induction in other programming applications.

Abstract

Exploration of ethnomathematics in the context of flat geometry, especially triangles, in traditional Batak Toba clothing, is an interesting and important study. This study aims to reveal the relationship between mathematical concepts and local culture, and how geometric elements can be found in the design of Sortopi traditional clothing. This research method uses a qualitative approach with data sources, namely library studies, from several literature reviews according to the topic and purpose of the study. The results of the study show that Sortopi is a complement to traditional Batak clothing used by men as a crown or headband. The shape of Sortopi contains elements of isosceles triangle flat geometry, thus showing that cultural elements are inseparable from mathematics.

Abstract

This study aims to examine the application of mathematical concepts, such as proportion, and symmetry, in traditional Batak house architecture through an ethnomathematics approach. The method used is a literature study, where data is obtained from various written sources, such as books, scientific journals, and related articles. The analysis was carried out by content analysis, namely by identifying and categorizing the main themes that appear in the literature, then synthesized to understand how Batak local wisdom reflects the application of mathematical concepts in the design and construction of traditional houses, especially Bolon houses. The results of the study indicate that the Batak people traditionally apply mathematical principles in creating strong, aesthetic, and symbolic building structures, and are relevant to their cultural values. This study reveals that the concept of ethnomathematics plays an important role in understanding the relationship between mathematics and local culture.

Abstract

This study examines the implementation of the fourth-order Runge-Kutta method in simulating bullet trajectories in the Earth's gravitational field. Bullet trajectory simulation is important in various fields such as ballistics and engineering, where the accuracy of predicting the trajectory of a moving object is crucial. The introduction explains the importance of using numerical methods in solving complex equations of motion, considering that analytical solutions are often inadequate. The purpose of this study is to apply the Runge-Kutta method to solve nonlinear differential equations describing the motion of a bullet under the influence of gravity. The research methods include modeling the motion system using Newton's laws and applying the Runge-Kutta method to predict the trajectory based on initial conditions such as velocity and firing angle. The simulation results show that the Runge-Kutta method provides accurate predictions of bullet trajectories, with low relative errors compared to other numerical methods. In conclusion, this method is effective and efficient in simulating bullet trajectories, providing reliable results in practical applications.
