“…Furthermore, from the discovery of several mathematical aspects of Batak culture, such as geometric transformations in gorga (C. Ditasona, 2018), arithmetic sequences on gorga carvings (Candra Ditasona et al, 2021), 2d and 3d geometry concepts in traditional house (Hidayat et al, 2020), fractals on gorga motifs (Situngkir, 2012), the concept of flat geometry on ulos (Rahmadani & Reflina, 2023), as well as the integral concept of the taganing musical instrument can be utilized as a learning resource for local students. Thus mathematics is no longer seen as something abstract and foreign to students.…”

“…It takes special skills possessed by the sculptor to make gorga. Previous studies have shown that the concepts of transformation geometry and arithmetic sequences are used in making gorga (C. Ditasona, 2018;Candra Ditasona et al, 2021). Based on these findings, this study aims to analyze the patterns of symmetry in the various gorga motifs.…”

As one of the traditional ornaments of the Batak Toba tribe, "gorga" carries philosophical meaning and serves to embellish the decoration of traditional houses. The gorga motif has its own distinctive characteristics, with closely arranged patterns and symmetrical designs. This indicates the presence of mathematical aspects within these carved gorga patterns. This research aims to analyze the symmetries embedded in the gorga motifs that can be utilized as locally-based mathematics teaching material. The study is conducted by exploring various gorga motifs and analyzing their types of symmetry. The research is employing an ethnographic research approach. Data is collected through observing buildings adorned with gorga motifs, studying literature, and conducting interviews with gorga carvers. Qualitative data analysis can be started with data reduction, data presentation, drawing conclusions and verification. The research findings reveal the existence of seven types of symmetry obtained from all gorga motifs. These symmetry types include translation symmetry, glide reflect symmetry, vertical symmetry, rotation 180° symmetry, vertical and rotation 180° symmetry, horizontal symmetry, and vertical and horizontal symmetry.

“…The relationship between mathematics and culture that underlies human activity is called ethnomathematics (Sari et al, 2021;Alghadari & Son, 2018;Ditasona, 2018;Ditasona, Turmudi, & Rosjanuardi, 2021). The idea of incorporating sociocultural elements into mathematics was initiated in 1977 by a Brazilian mathematician named Ubiratan D'Ambrosio.…”

Ethnomatematics is an intersection between mathematics and culture, making it a study of mathematical concepts within a specific cultural context. In line with this, the present research aimed to explore the mathematical concepts present in the Tafatik Maromak Oan traditional house. This research is qualitative research with an ethnographic approach. This research was conducted in August 2022 in Wehali Village, Central Malaka District, Malaka Regency. The instruments used are observation guidelines, interview guidelines, and documentation. Participants in this study consisted of 4 people with details of 1 King (Nain), 1 traditional housekeeper (fukun), 1 craftsman and 1 community member. The stages in this study consisted of domain analysis, taxation analysis, componential analysis, analysis of cultural themes, and drawing conclusions. The results of this study indicate that the mathematical concepts contained in the Tafatik Maromak Oan Malaka traditional house are geometric concepts including rectangles, squares, triangles, circles, lines, cylinders and trapezoids.

“…Research on ethnomathematics has been widely carried out in previous studies, one of which is on the ornaments of traditional houses in an area (Ditasona et al, 2022;Fitriza, 2018;Nurhikmah et al, 2019;Utami et al, 2021). These studies provide an understanding that in traditional house ornaments, there are mathematical ideas that are found and applied to traditional houses.…”

This study aimed to explore the arithmetic sequence pattern found in Minangkabau carvings mounted on singok gonjong. The method used is a qualitative method with an ethnographic approach. Data was collected by observation, interviews, literature studies, and documentation. The object of this study is Minangkabau carving on singok gonjong. The data obtained in this study came fromdirect observation, results of interviews with Minang carving craftsmen, documentation, and literature studies. The results showed three kinds of arithmetic sequence patterns in Minang carvings in singok gonjong. The first is the arithmetic sequence pattern on the saik galamai carving with formula Un = n. The second is the pattern of odd and even arithmetic sequences on the sikambang manih carving wtih the odd formula U(2n+1) = 3n + 1 and the even formula U(2n) = 3n. The last is the pattern of odd and even arithmetic sequences on the combined engraving of saik galamai and sikambang manih wtih the odd formula U(2n+1) = 4n + 1 and the even formula U(2n) = 4n. The conclusion shows that the presence of patterns on the saik galamai carvings and sikambang manih carvings found on Singok Gonjong can be used as a preference for learning arithmetic sequences at school
