Abstract

AbstrakKegiatan ini bertujuan untuk memberikan pendampingan pembuatan alat peraga inovatif dalam meningkatkan pemahaman matematis siswa pada materi geometri di SLB-C Pancaran Kasih Kota Cirebon.  Kegiatan pendampingan dilakukan di SLB-C Pancaran Kasih Kota Cirebon pada semester genap tahun ajaran 2023/2024. Pada kegiatan ini melibatkan kolaborasi antara dosen dan mahasiswa Tadris Matematika UIN Siber Syekh Nurjati Cirebon, serta  siswa dan guru-guru matematika di SLB-C Pancaran Kasih Kota Cirebon. Metode yang digunakan dalam kegiatan ini adalah pendekatan penelitian Participatory Action Research (PAR) yang mencakup pemberian pengetahuan tentang macam-macam alat peraga inovatif yang dapat digunakan untuk meningkatkan pemahaman matematis siswa pada materi geometri, bimbingan dalam merancang dan membuat alat peraga inovatif, serta pendampingan implementasi penggunaan alat peraga di kelas, dan evaluasi kegiatan. Hasil pendampingan menunjukkan bahwa pendampingan pembuatan alat peraga inovatif efektif dalam meningkatkan kemampuan guru matematika di SLB-C Pancaran Kasih Kota Cirebon dalam merancang, membuat dan menggunakan alat peraga inovatif pada materi geometri di kelas. Hasil pendampingan juga menunjukkan bahwa kemampuan pemahaman matematis siswa pada materi geometri di SLB-C Pancaran Kasih Kota Cirebon meningkat. Aspek kepuasan siswa terhadap penggunaan alat peraga dalam pembelajaran geometri menunjukkan rata-rata sebesar 76% berada dalam kategori "Puas". Aspek kepuasan siswa terhadap kualitas alat peraga geometri menunjukkan rata-rata sebesar 78% berada dalam kategori "Baik". Aspek kepuasan guru terhadap penggunaan alat peraga dalam pembelajaran geometri menunjukkan rata-rata sebesar 76% berada dalam kategori "Puas". Kata kunci: alat peraga; pemahaman matematis; geometri. AbstractThis activity aims to provide guidance on the creation of innovative teaching aids to improve students' mathematical understanding of geometry at SLB-C Pancaran Kasih in Cirebon City.  The guidance activity was conducted at SLB-C Pancaran Kasih in Cirebon City during the second semester of the 2023/2024 academic year. This activity involves collaboration between lecturers and students of the Mathematics Education program at UIN Syekh Nurjati Cirebon, as well as students and mathematics teachers at SLB-C Pancaran Kasih in Cirebon City. The method used in this activity was the Participatory Action Research (PAR) approach, which included providing knowledge about various innovative teaching aids that can be used to enhance students' mathematical understanding of geometry, guidance in designing and creating innovative teaching aids, mentoring the implementation of teaching aids in the classroom, and evaluating the activity. The results of the mentoring showed that the mentoring in creating innovative teaching aids was effective in improving the ability of mathematics teachers at SLB-C Pancaran Kasih in Cirebon City to design, create, and use innovative teaching aids for geometry lessons in the classroom.

Abstract

This article discusses the simulation of planetary movements in the solar system using a linear system-based approach. Mathematical models of solar systems often involve non-linear differential equations, which include the complexity of gravitational interactions between planets and other celestial bodies. However, to simplify the calculation and analysis process, a linear approach can be used with certain assumptions. In this study, the motion of the planets is modeled using Newtonian mechanical principles adapted into a linear equation system. The simulation is carried out by utilizing numerical computing software to calculate the position and speed of the planet in a certain time span. The simulation results show that the linear system approach is able to represent the basic motion of the planet with an adequate degree of accuracy on short time scales, but it shows limitations in predicting complex dynamics, such as orbital resonance or the gravitational influence of small bodies. This approach is suitable for educational applications, where visualization of planetary movements can help understand the basic principles of orbital dynamics. These findings emphasize the importance of choosing the right simulation method according to the purpose, both for scientific and educational purposes. The study suggests the development of a hybrid model that combines a linear approach with non-linear elements to improve accuracy without losing computational efficiency.
