Abstract

This research aims to analyze ethnomathematics in a mosque named Gedhe Kauman in Yogyakarta. The ethnomathematics studied is related to the mathematical concepts of area and perimeter of two dimensional shapes. This research is qualitative research with an ethnographic approach. The data source in this research is the result of direct observation and documentation by the researcher. Data collection techniques were carried out by observing and documenting mosque buildings. Testing the validity of the data was carried out using technical triangulation. The subject of this research is the historic building of the Gedhe Kauman Mosque. Based on the research results, it was found that the Mosque building is quite closely related to ethnomathematics learning resource. This is proven by the presence of geometric elements in the structure and contents of the building that have easyly reognized patterns. The geometric shapes found are squares, rectangles, circles, triangles and trapezoids. These plane shapes can be integrated into the mathematical concepts of perimeter and area for learning elementary mathematics. This instructional approach might evoke student's disposition towards mathematics.

Abstract

This study aims to explore the traditional clothes of the Dayak Kenyah tribe and is related to the concept of geometric transformation. This type of research is qualitative research with an ethnographic approach. The subject of this research is the traditional clothes and accessories of the Dayak Kenyah tribe, while the object of this study is the geometric transformation concept of the Dayak Kenyah in traditional clothes motifs. Data was collected through observation, interview, and documentation in traditional clothes of the Dayak Kenyah tribe. Based on the exploration results, it was found thirteen traditional clothes and accessories for the Dayak Kenyah traditional clothes (Bluko, Besunung, Tabit, Kelempit, Baheng, Sapai, Ta'a, Tapung, Sabau, Uleng, Seleng, Kirip, and Anting) which are examples of the application geometric transformation concepts. The results of the research show that the motifs found in the traditional clothing of the Dayak Kenyah tribe can be a concrete example of the concept of geometric transformation. The geometric transformation concepts found include (1) Translation in Tabit, Kelempit, Ta'a, and Sabau; (2) Reflections in Bluko, Tabit, Kelempit, Sapai, Ta'a, Tapung, Sabau, Uleng, Seleng and Earrings; (3) Rotation of the Tabit; (4) No dilatation was found in the traditional clothes motifs of the Dayak Kenyah tribe. Apart from that, in Besunung, Baheng, and Kirip, there is no concept of geometric transformation. The example represented in the traditional clothes of the Dayak Kenyah tribe can then become an alternative recommendation for learning media so that students can better interpret geometric transformation material contextually.

Abstract

The continuous exploration of the role of mathematics underscores the significance of ethnomathematics research. Ethnomathematics investigates mathematical concepts embedded within diverse cultures. Among the rich array of ethnomathematical objects, Javanese traditional houses stand out as a promising area for investigation. These houses, deeply rooted in a rich cultural heritage, offer substantial potential for understanding and the concrete application of mathematical principles. This study, employing a systematic literature review, aimed to explore the various mathematical concepts inherent in Javanese traditional houses. Data were systematically collected from Google Schoolar (2019-2023), with a specific focus on articles discussing ethnomathematics in traditional houses. The findings reveal the pervasive presence of ethnomathematics within the architecture of Javanese traditional houses, encompassing mathematical concepts such as plane and solid geometry, liners, and geometric transformations (translation, reflection, rotation, dilation) as well as similarity and congruence.
