Abstract

Numerical concepts practiced in different societies and hereinafter alluded to as ethnomathematics have been broadly displayed in writing. But the picture of the ethnomathematics practiced in planning the building of Sambas malay traditional house, has not been investigated. The reason of this investigate is to investigate ethnomathematics as a bridge between culture and science so as to depict the numerical concepts contained within the plan of Sambas malay traditional house. The object of his research is ethnomathematics in the design of Sambas malay traditional house. In this research, the type of research that has been used was exploration. While the method of data collection using observation, interview, and documentation. The object of his research is ethnomathematics in the design of Sambas malay traditional house. In this research, the type of research that has been used was exploration. While the method of data collection using observation, interview, and documentation. The results revealed that Sambas Malay tribe has used mathematical and geometric concepts in building traditional houses. In this case it has been found in the form of symmetry axes on the foundation of the architecture that serves to facilitate the placement of space so that there is a balance of load distribution thus the building becomes more stable. In addition, mathematical concepts that have been used in the design of Sambas Malay traditional house among other vertical lines, horizontal lines, parallel lines, perpendicular lines, field geometry (equilateral triangles, equilateral trapezoids, rectangles, semicircular, right triangles, arbitrary rectangles, squares and right trapezoids), spatial geometry (prisms), transformational geometry (reflection, translation, rotation, and dilation), colorism, revival, concept of folding symmetry, numbers, and angles.
