This research was conducted to develop the textbook of the basic science concepts contained ethnoscience. The formulation of the problem in this research is about how the characteristics and feasibility of the textbook of the basic science concepts contained ethnoscience for PGSD student. The research method used is the R&D research method. The research subjects were 22 STKIP NU Indramayu students who took basic science concept of lectures. The instruments used were expert validation sheets and questionnaires. The research plan begins with initial data collection, field studies, making the textbook of basic concepts contained ethnoscience, then proceed with expert validation by the validators using the developed expert validation instrument. After going through the revision of the validators regarding textbook, a trial of the textbook was developed for students by using a questionnaire to find out the user's response to the feasibility of the textbooks of basic science concepts contained ethnoscience. The results of expert validation are 94.5, and it's categorized very validly. Meanwhile, the results of user responses questionnaire are 81.60 with a very decent category.
