PEMBELAJARAN MATEMATIKA DALAM KEBUDAYAAN REOG PONOROGO (KAJIAN ETHNOMATHEMATICS)

Abstract

Abstract: Mathematical learning that is done now tends to be too dry, theoretical,
less contextual, and pseudo. Learning is also less varied, thus influencing students’
interest in learning mathematics at school. Therefore learning mathematics is very
necessary to provide content / bridge between mathematics in everyday world based
on the local culture with school mathematics. The bridge is ethnomathematics. Reog
Ponorogo, which is considered as the cultural center of the people in Ponorogo, East
Java, is a local culture that needs to be preserved and preserved not only for the people
of Ponorogo but also for the whole world. The purpose of this article is to conduct
an assessment, extracting ethnomathematics on Reog Ponorogo art instruments
specifically on the concept of geometry. The results showed that a rectangle was found
in front of the peacock and penandhon clothes, the square concept was found in udeng,
the trapezoidal concept was found in dhadak merak, the concept of lines and angles
was found in angklung and gong kempul and in drawings, the concept of circles
