Development of Ethnomathematical Media Based on the Book Creator Application on the Syawalan Tradition in the Junior High School Curriculum

Culture-based learning enables teachers and students to
participate actively based on their knowledge about culture,
producing optimal learning results. Ethnomathematics,
particularly math, is a potential bridge gap Between culture and
education. Because of that's very important to plan appropriate
teaching materials in Pasuruan with characteristics of learning
mathematics-based ethnomathematics in traditional syawalan.
Study this aim for make product in the form of a book -based
creator ethnomathematics in understand draft for could
complete problem mathematics, as well knowing response and
results in study student after using learning media on the
material algebra. The techniques used are descriptive and
qualitative using ethnomathematics e-books. The development
used a 4D model consisting of 4 stages: definition, design,
development, and stage dissemination. Instruments used
shaped responses students through sheet questionnaires and
test results studied through sheet tests. Based on validity test
analysis by (media, materials, and experts culture), practicality
test through response student gets average score 3.62 with
category excellent practicality, effectiveness test, and analysis
ability understanding draft student through test understanding
completeness study by 82 percent. So that could conclude that
the developed ethnomathematical e-book media in traditional
syawalan "lontong vegetables” for increase understanding draft
middle school students about operation algebra worthy used to
enhancement understanding draft students because of Fulfill
valid, practical, and effective criteria.
