Abstract

In this increasingly sophisticated era, technology is also very often used in any situation. The use of various types of technology is growing so rapidly that learning activities in the field of technology have emerged which are usually called programming. Programming is also very interesting in the eyes of students because there are courses that are directly related to programming, namely Programming Algorithms. In programming, there are several types of languages ​​that are often used, for example the C and C++ programming languages. The C and C++ programming languages ​​are programming languages ​​that can simplify calculations in mathematics subjects, especially in the basic concepts of Arithmetic and Integers by using integer data types which contain numbers. So this literature concept study really makes it easier for programming users and readers to better understand the C and C++ programming languages ​​in calculating basic operations of Arithmetic Operators as well as calculations with simple codes on integers.

Abstract

This research employs a Systematic Literature Review (SLR) approach to analyze the application of the simplex method as a tool for solving real-world optimization problems. Mathematics education plays a crucial role in developing critical thinking and achieving accurate results. Linear programming, with its highly effective simplex method, is a branch of mathematics proven to solve various optimization challenges such as cost minimization, profit maximization, distribution, and scheduling. In practice, the simplex method is an alternative algorithm that systematically searches for the optimal solution to problems by moving from one feasible solution to another until the best result is achieved. This study identifies, examines, evaluates, and interprets relevant studies on the simplex method's application in real-world contexts. Our review of 20 journals reveals that the simplex method is highly effective in solving a wide range of optimization problems, from large-scale industries to Micro, Small, and Medium Enterprises (MSMEs). Examples of its application include optimizing fish feed costs at PT. Indojaya Agrinusa, maximizing profits for Seblak MSMEs, determining optimal sales quantities for areca nuts, and optimizing the production of tofu and pottery crafts, among others. The simplex method's ability to consider various limiting factors has proven to be extremely helpful.

Abstract

The issue of plastic waste is increasingly becoming an environmental concern, including in elementary schools, due to its non-biodegradable nature and its potential to cause environmental pollution if not properly managed. This activity aims to implement the Ecobrick method as an innovative solution for managing and utilizing plastic waste at SDN 054945 Desa Dogang, Gebang District, Langkat Regency. The method used is a descriptive qualitative approach involving 65 students from grades IV and V through a community service activity. The activity was carried out on July 17, 2024, through preparation, implementation, and evaluation stages, with data collection techniques including observation, documentation, and reflective discussion. The results show that the application of the Ecobrick method successfully increased students' understanding and awareness of the dangers of plastic waste and fostered an early environmental concern. Moreover, previously worthless plastic waste was processed into functional Ecobrick benches that can be utilized within the school environment. This activity also encouraged a sense of mutual cooperation, responsibility, and creativity among the students. Thus, the Ecobrick method has proven to be an effective alternative for plastic waste management and a contextual learning medium in creating an environmentally friendly school culture.
