Javanese Culture as An Object of Ethnomathematics In The Development of E-LKPD Online Learning Era 4.0
Ki Hadjar Dewantara taught the spirit and how to educate Indonesian children to become independent human beings. This policy provides convenience in online learning conditions with all the limitations of space. Various content available in cyberspace allows students to do more online activities. If there is no self-monitoring and awareness, online activities will actually erode the values of the nation's noble cultural character. Considering the importance of ethnomathematics to the formation of students' noble cultural characters, a study was conducted that aims to develop an online inquiry learning model based on Javanese Cultural Ethnomathematics in Era 4.0. The research conducted is in the form of research and development which consists of five stages referring to the educational development model of Plomp. The results of the research have been carried out until the first stage, namely field observations, literature studies and FGDs. Field observations were carried out by observing 10 (ten) cultural sites located in the Provinces of the Special Region of Yogyakarta (DIY), Central Java, and East Java. The results of observations and FGDs show that out of ten cultural sites have unique ethnomathematical characteristics, but broadly speaking, ethnomathematical elements related to geometric concepts can be divided into plane geometry and spatial geometry.
