Ethnomathematics: Modelling the volume of solid of revolution at Buginese and Makassarese traditional foods

Ethnomathematics can empirically improve the cognitive abilities of students in elementary and secondary schools. However, undergraduate study, there are still limited studies on integrating ethnomathematics learning resources. This study aims to apply interpolation modelling polynomial functions integral volume shape Buginese Makassarese traditional foods. Furthermore, it be used by as relevant resources regarding concept solid revolution (VOSR). is a qualitative using an ethnographic approach. The data were collected through observations obtain general information, interviews with informants find out food-making techniques, documentation physical models each type food. Data Analysis Techniques consist domain analysis overview foods taxonomic categorize mathematical concepts obtained from modeling simulation. result this research reveals that lammang suitable slabs. It represented constant revolved around x-axis or y-axis. While paso, bolu cukke, cantik manis well barongko batara, Putu, cucuru outlined linear rotating about x-axis, y-axis, others fixed-line. They meet criteria disks method. they described function polynomials n-degree. use washers model blundered sarang semut hole middle caused intersection two curves rotated For shells, applied determine cover pisang ijo flour onde-onde. Thus, all types appropriate objects for resource VOSR.
