EKSPLORASI ETNOMATEMATIKA PADA AKTIVITAS PERTANIAN MEDIA HIDROPONIK DI KOTA TANJUNGPINANG
The lack of use of culture in learning at school makes learning boring and boring for students. This study aims to dig up information on ethnomathematics in hydroponic media farming activities and relate the results of ethnomathematics research to mathematics learning resources based on the school curriculum. This research is a quantitative research of ethnographic design. The data collection technique used was the observation method, interviews with the owner of the Tanjungpinang hydroponic media farm, Mr. Adhex Masdar, and documentation with the main instrument, namely researchers with the help of companion instruments in the form of observation sheets and interview sheets.
