Mathematics and culture are two things that cannot be separated. Mathematics and culture have always been inherent in everyday life. The relationship between mathematics and culture is known as ethnomathematics. There are many ethnomathematics in Indonesia still dug. At Ratu Boko Temple there are several mathematical elements that can be found. Ethnomathematics also could be used for new innovation in math learning. The purpose of this study is two, analyzing the ethnomamatic concept that exists in Ratu Boko Temple in terms of aspects of the study (1) flat geometry and (2) geometry of space. Type of ethnographic qualitative research. Data collection through interviews, observations, and documentation. Validity of data with the triangulation of sources and techniques. Data analysis techniques induction of data. The results of the study are two. (1) At Ratu Boko Temple found elements of flat geometry, including square, rectangle, triangle, circle, trapezoid, and octagon. (2) At Ratu Boko Temple found elements of space geometry, including rectangular prism, cylinder, cones, frustum a cones, and rectangular pyramid. The concept of plane geometry and space geometry contained in the temple can be utilized by teachers in conveying material to students. Mean in everyday life at Ratu Boko Temple found ethnomathematics as math learning in school.
