This study aims to explore the ethnomathematics of Javanese society using cultural elements of living equipment and technology systems that are based on geometry perspective. The method used in this study was exploration. Data collection was collected through document collections, interviews and observations. Life equipment and technology systems includes in the form of transportation equipment, housing, and clothing materials. Types of transportation equipment, housing, and clothing are artefacts. Mathematics elements are explored on horse-drawn carriages, Joglo houses and batik (Lereng, Ceplok, and Jlamprang motifs). This research is important to explore information related to ethnomathematics in Java that can be used for mathematics in schools. Batik motifs (Lereng, ceplok, and Jlamprang) are ethnomatematics related to lines and angles, triangles and quadrilaterals, circles. Ethnomatematics in Joglo homes can be associated with line and angle material, triangles and quadrilaterals, constructing flat side spaces, building curved, congruent and Pythagorean theorems. Ethnomatematics in horse-drawn carriages can be associated with constructing curved side spaces. © Published under licence by IOP Publishing Ltd.
