Abstract

Abstract. The travelling salesman problem is one of the classic optimisation problems that is widely applied in real life, such as in the distribution of goods, transportation route planning, and even the movement of industrial robots. This study aims to implement algorithms for solving the travelling salesman problem using two different programming languages, namely Pascal and C++, and to compare their performance in terms of effectiveness, memory efficiency, and execution speed. The methods used include weighted graph modelling, shortest path calculation, and the application of the Branch and Bound algorithm. The test results show that both programming languages produce identical optimal routes, namely 1 – 5 – 6 – 7 – 10 – 9 – 8 – 4 – 2 – 3 – 1 with a minimum total distance of 196. The Pascal programme has the advantage of a simple syntax structure and low memory usage (±356 KB), while C++ excels in execution speed (0.09466 seconds) despite having a larger output file size (±1.26 MiB). This difference in performance indicates that Pascal is more suitable for educational purposes and small-scale applications, while C++ is superior for complex applications and modern system integration needs. Thus, the TSP algorithm can be implemented effectively using either Pascal or C++, and the choice of programming language should be tailored to the context of the requirements.

Abstract

Aras Village is a village in Air Putih District, Batu Bara Regency, North Sumatra Province. The people who live in the Aras Village area are farmers, fish cultivators and traders. The partner's problem is that they have never received training in making independent feed and evaluating their cultivation business. So far, fish farmers in Aras Village still rely on factory-made feed, causing the price of the feed product to be very high, reaching 70% of the total production costs and they cannot evaluate their business. The aim of community empowerment activities is to assist fish farmers in managing and increasing fish farmers' income in managing catfish cultivation. The priority aim of community service carried out by lecturers is to improve the economy. The stages of the implementation method used are outreach and training to the community on how to make good and healthy fish food. Socialization, training and assistance to the catfish farming community on how to evaluate catfish cultivation businesses by calculating income, expenses, BEP, B/C ratio and NPV (overcoming management problems). Evaluation of program implementation is carried out every time an activity is carried out, such as socialization, training and mentoring. Socialization and training on making independent feed and evaluating fisheries businesses is going well in Aras Village, Air Putih District, Batu Bara Regency. The program evaluation results show that as many as 80% of cultivator groups can know how to make feed independently and evaluate their efforts.

Abstract

Learning media in general is a tool for teaching and learning. Everything that can be used to stimulate the thoughts, feelings, attention and abilities or skills of students so as to encourage the learning process. This limitation is quite broad and includes the understanding of resources, environment, people and methods used for learning / training purposes. Barriers to the use of teaching aids in supporting student interest in learning, obstacles include: conditioning students' attention to learning with teaching aids, teacher learning methods that tend to be less varied so that students are less enthusiastic in learning if the teacher is monotonous, the teaching aids available in schools are incomplete, making teaching aids in accordance with the material and student input is difficult, the minimum time to prepare learning with teaching aids.

Abstract

The National Examination, usually abbreviated as UN, is a system of evaluating the national primary and secondary education standards as well as the equality of education quality between regions carried out by the Education Assessment Center. Algebra is a part of a large field of mathematics, together with number theory, geometry and analysis. In its most common form, algebra is the study of mathematical symbols and their rules. The method used in interactive learning was chosen to deliver appropriate training which was carried out in three stages, namely the field exploration stage, the implementation stage, and the evaluation stage. With this method, it is hoped that teachers and students can see quick tricks on solving the National Mathematics Examination questions.

Abstract

Mathematics is a subject whose field of study is abstract and requires the ability to think logically so that to convey it, a medium is needed so that students become more understanding of the material presented and stimulate students to improve their ability to think logically. One of the learning media that is in accordance with current developments is the use of software. Using the GeoGebra Software provides several advantages, including geometric drawings which are usually produced more quickly and accurately than using a pencil, ruler or compass. The existence of animation facilities and manipulation movements (dragging) in the GeoGebra Software can provide a clearer visual experience for students in understanding geometric concepts. Can be used as an evaluation to ensure that the painting that has been made is correct. Make it easier for teachers and students to investigate or show the properties that apply to a geogebraic object. The method used in this activity is an interactive lecture that is chosen to deliver software geoebra which is carried out in three stages, namely the field assessment stage, the implementation stage, and the evaluation stage. By using this GeoGebra software, it can increase the knowledge and understanding of teachers in learning mathematics and can produce teaching materials based on GeoGebra.
