Abstract

This community service program (PKM) is one of the activities of the Tridarma of Tinngi College. In this case, this PKM activity was carried out in one of the junior high schools in Tanjung Morawa, namely SMP IT AL IKHWAN Tanjung Morawa. The purpose of this PKM activity is to assist teachers in socializing learning media based on Acehnese culture that can be used in learning, especially for students at the junior high school level. This activity aims to enable teachers to apply Acehl culture-based learning media so that learning in the classroom is more attractive to students. This PKM activity was carried out at SMP IT AL IKHWAN Tanjung Morawa., and was attended by 12 teachers offline (face-to-face). This activity is carried out in 3 stages. The first stage introduces culture-based learning media. The second stage demonstrates the preparation of digital learning media, and the last stage allows teachers to apply learning media in the classroom. The output targets that will be achieved in PKM activities are: (1) teachers can understand Acehnese culture-based learning media, (2) improve teachers' pedagogic competence, (3) teachers can compile digital-based learning media, (4) teachers can apply learning media in the classroom, (5) increase students' interest in learning. The implementation of this PKM went smoothly because all participants were active in the PKM activities and could apply it during the learning process in the classroom.

Abstract

Fourier series has the ability to decompose a periodic function into a collection of sine and cosine wave sums. Another way to express a function into an infinite series is with the Maclaurin series or Taylor series but both of these series require that the function must have the first derivative, the second derivative and so on of the function is defined at its expansion point and there must be no discontinuity value at that point. However, the advantage of the Fourier series is that we can decompose the function into an infinite series containing the sum of sine and cosine terms even though the function cannot be differentiated and has discontinuity at some points. The Fourier series equation of an analytical function is obtained by first finding the values ​​of the Fourier coefficients using analytical integrals. In the case of functions formed from numerical data that are assumed to have a periodic pattern, the Fourier series formula that uses analytical integrals to find its Fourier coefficients can no longer be used so that the numerical approach using the Trapezium method is an alternative that allows us to find the Fourier series equation for a periodic function expressed numerically. We use 12 points as the basis for the calculation in the Trapezium method to approximate the Fourier series numerically. This paper presents a numerical approach to solve the problem.

Abstract

The The ability to understand concepts is the ability to understand and account for an idea as well as the ability to think logically, critically, creatively and innovatively. The research objective of this study is to look at the profile of the ability to understand concepts through PjBL learning in terms of students' learning styles in understanding mathematical concepts in class VIII-A statistics material at MTs Al-Mahrus Mabar. The method used in the research is descriptive qualitative research. The research location is Jalan RPH LINK.IV Mabar Hilir Medan and the research time was carried out in the 2023/2024 academic year. The research subjects were 6 students from 22 students, where the researcher chose 2 students each with visual, auditory and kinesthetic learning styles based on the student learning style questionnaire that had been given. The researcher's data collection method used four techniques, namely observation, interviews, questionnaires and concept understanding ability tests. Data analysis is carried out by reducing data, presenting it, and drawing conclusions. The research results show that students with kinesthetic learning styles understand mathematical concepts better than students with visual and auditory learning styles. Students with a kinesthetic learning style are able to understand three of the four indicators of conceptual understanding, while students with a visual style, the same as students with an auditory learning style, are only able to understand two of the four indicators of conceptual understanding.
