Abstract

Ethnomathematics is a culture-based learning concept in the context of mathematics. The presence of mathematics with cultural nuances will make a major contribution to learning mathematics. The purpose of this study is to identify and describe mathematical objects and concepts found in Malay culture at the Kamu market. This type of research is qualitative research with ethnographic methods. Data analysis techniques used are literacy studies, observation, interviews, and documentation. The results showed that the culture at Kamu market has various ethnomathematics concepts found in traditional cakes from various regions such as Katimus cakes, Gadong cakes, Dangai cakes, Karas cakes, Lapet cakes, and Putu Bambu cakes. The mathematical concepts found are geometric shapes such as rectangles, spheres, cuboids, isosceles triangles, quadrilateral pyramids, and cylinders. This ethnomathematics exploration can be used as a learning medium that is expected to help and add insight into understanding the concepts of flat shapes and geometric shapes in learning mathematics.Keywords: ethnomatematics; culture; geomteryAbstrakEtnomatematika merupakan konsep pembelajaran berbasis budaya dalam konteks matematika. Kehadiran matematika yang bernuansa budaya akan memberikan kontribusi besar dalam pembelajaran matematika. Tujuan dari penelitian ini adalah untuk mengidentifikasi dan mendeskripsikan objek dan konsep matematis yang terdapat pada budaya Melayu di pasar Kamu. Jenis penelitian ini adalah penelitian kualitatif dengan metode etnografi. Teknik analisis data yang digunakan adalah studi literasi, observasi, wawancara, dan dokumentasi. Hasil penelitian menunjukkan bahwa budaya di pasar Kamu memiliki berbagai konsep etnomatematika yang terdapat pada kue tradisional dari berbagai daerah seperti kue Katimus, kue Gadong, kue Dangai, kue Karas, kue Lapet, dan kue Putu Bambu. Konsep matematika yang ditemukan adalah bentuk-bentuk bangun geometri seperti persegi panjang, bola, balok, segitiga sama kaki, limas segiempat, dan tabung. Eksplorasi etnomatematika ini dapat digunakan sebagai media pembelajaran yang diharapkan dapat membantu dan menambah wawasan dalam memahami konsep bangun datar dan bangun ruang dalam pembelajaran matematika.Kata Kunci: etnomatematika; budaya; geometri

Abstract

This study aims to explore and describe the mathematical concepts embedded within the Gedogan Karo weaving loom at the Jamin Gintings National Hero Museum. The primary focus is to identify the application of ethnomathematics in the tool's structure and the process of weaving traditional Karo cloth (Uis Karo). The methodology employed in this research is qualitative with an ethnographic approach. Data were collected through direct observation of artifacts in the museum, technical documentation, and a literature study regarding the weaving techniques of the Karo people to dissect the underlying mathematical elements. The results and discussion indicate an integration of formal mathematical concepts across four main aspects: (1) Geometry, through the formation of parallel lines in the warp threads and perpendicular relationships in the weft threads; (2) Geometric Transformation, evident in the symmetry, reflection, and translation patterns of the Uis Karo motifs; (3) Binary Logic, in the thread-lifting technique that resembles computer algorithm systems; and (4) Trigonometry, in the thread tension mechanism which depends on the leaning angle of the weaver's body. The conclusion of this study is that the Gedogan Karo loom is a manifestation of local wisdom that intuitively applies complex mathematical principles. The author suggests that these ethnomathematical exploration results be integrated into the formal mathematics education curriculum as contextual learning material. This is crucial for increasing students' interest in mathematics while simultaneously strengthening efforts to preserve Karo cultural heritage in the modern era.

Abstract

This research aims to develop a mathematics learning medium in the form of an Indonesian culture-based e-comic integrated with the educational values ​​of Imam Syafi'i on the topic of Two-Variable Linear Equation Systems (SPLDV) to improve the mathematical problem-solving skills of students at SMP IT Al Maidani. The urgency of this research is based on the low mathematical problem-solving abilities of junior high school students, as well as the lack of contextual, engaging, and Islamic character-infused learning media. The development model used was the 4D model (Define, Design, Develop, Disseminate). The research subjects consisted of 30 students in the first trial and 32 students in the second trial. Validation was conducted by media experts, material experts, religious experts, and cultural experts. The validation results indicated that the developed learning medium was valid with an average score of 4.3 (media experts), 4.2 (material experts), 4.4 (religious experts), and 4.5 (cultural experts). The first trial resulted in an increase in the average score from 76.9 (pretest) to 83.73 (posttest), with an N-Gain of 0.32 (moderate category). Based on the reflection results of the first trial, revisions were made, including improvements to the interface, the addition of sample verification questions, and additional contextual exercises. After revisions, the second trial showed a significant increase, with an average score from 77.4 to 94.25 and an N-Gain of 0.78 (high category). A total of 87.5% of students achieved classical learning completion. The results of the study demonstrate that the developed e-comic media is valid, practical, and effective in improving students' mathematical problem-solving skills and instilling Islamic character values ​​aligned with the educational values ​​of Imam Syafi'i.

Abstract

Penelitian ini bertujuan untuk mengkaji peran media pembelajaran berbasis IT dalam meningkatkan kemampuan komunikasi matematis siswa. Metode yang digunakan adalah studi pustaka dengan menganalisis beberapa penelitian relevan yang dipublikasikan pada tahun 2024 terkait pemanfaatan teknologi informasi dalam pembelajaran matematika. Hasil kajian menunjukkan bahwa berbagai bentuk media berbasis IT, seperti video animasi, e-modul berbasis Android, perangkat lunak matematika, dan model flipped classroom, memberikan kontribusi positif terhadap kemampuan siswa dalam mengekspresikan ide matematis, merepresentasikan konsep, serta mengomunikasikan proses penyelesaian masalah baik secara lisan maupun tertulis. Media berbasis IT memfasilitasi visualisasi dan interaktivitas sehingga membantu siswa memahami konsep matematika yang bersifat abstrak dan mengungkapkannya secara sistematis. Selain itu, penggunaan teknologi pembelajaran juga meningkatkan minat dan keterlibatan siswa dalam pembelajaran matematika yang mendukung perkembangan komunikasi matematis. Namun, efektivitas media berbasis IT sangat bergantung pada ketersediaan infrastruktur, kompetensi guru, dan perancangan pembelajaran yang tepat. Dengan demikian, media pembelajaran berbasis IT dapat diposisikan sebagai sarana strategis untuk meningkatkan kualitas pembelajaran matematika dan kemampuan komunikasi matematis siswa.
