Abstract

A multitude of software and media have been made possible by technological advancements, which may be utilized to produce more engaging and successful mathematics learning experiences. By using algorithms and programming languages, the software can run well. Reviewing educational materials that may be utilized to advance mathematical learning, together with their impacts and difficulties, is the goal of this study. This piece employs the technique of Systematic Literature Review (SLR). This SLR research aims to find, study, and evaluate comparable research to answer research questions. The development of mathematical learning through the use of learning materials based on algorithms according to previous research most people use geogebra and matlab. This study solely addresses the application of algorithm-based media programming in the advancement of mathematical learning, in accordance with earlier publications. It is anticipated that future academics will be able to advance mathematics learning using the algorithm-based media of this programming.

Abstract

Linear programming is a crucial operations research method for optimization problems in various fields like manufacturing and logistics, but it is often hindered by the absence of a basic feasible solution due to artificial variables. The Big M method addresses this by adding artificial variables and a large penalty, allowing the discovery of a valid initial solution without altering the constraint structure. This research employs a Systematic Literature Review (SLR) to examine the implementation of the Big M method in Indonesia from 2015-2025, analyzing journals and proceedings related to linear programming optimization. The review findings indicate that this method is highly effective and flexible for diverse cases such as production, animal feed, and scheduling, capable of handling artificial constraints and optimizing profit or cost. Although efficient, the Big M method has drawbacks, including computational complexity and dependence on the precise selection of the M value, which can affect result accuracy. Overall, the Big M Method remains relevant and important for real-world optimization problems requiring systematic constraint handling.

Abstract

The low level of interest and motivation among elementary school students in learning mathematics, particularly in plane geometry topics, remains a common problem. This community service activity aimed to improve students’ interest and understanding of plane geometry concepts through the implementation of the Inspiration Class as an educational medium that connects mathematical material with students’ aspirations. The activity was conducted at SDN 056024 Dogang, Langkat Regency, involving sixth-grade students. The implementation method employed a participatory and educational approach consisting of preparation, implementation, and evaluation stages. The activities included the delivery of plane geometry material, interactive discussions, and a creative project in the form of a “dream tree” using origami shaped into plane figures. The evaluation was performed qualitatively by observing student engagement and interactions in question-and-answer sessions, and analysis of students’ work. The results showed that the Inspiration Class created a more active and enjoyable learning atmosphere, increased student participation, and helped students better understand the concepts and properties of plane figures. In addition, this activity motivated students by linking mathematics learning with future aspirations and professions. Therefore, the Inspiration Class can be considered an effective alternative educational medium for teaching mathematics at the elementary school level.
