ETHNOMATHEMATIC STUDY OF HYPOTHETICAL GEOMETRIC STRUCTURES/SHAPES OF MEGALITHIC SITE OF GUNUNG PADANG Turmudi, Dadang Juandi, Yullys Helsa, Edi Supriadi, and Abdul Latip
This research is ethnographic qualitative research, involving stakeholders and communities around the Gunung Padang site in Cianjur, West Java. Information mining is directed at how stakeholders in the Gunung Padang site treat and perceive the existence of Megalithic Buildings in the Gunung Padang Site. Apart from that, public perception and literacy studies related to the shape or geometric structure of the Gunung Padang Site, were excavated to obtain a complete understanding of the site. Furthermore, triangulation of good data obtained through interviews, ethnography, interaction in the implementation of observations, as well as literary data is needed to obtain perfect information in order to build a Hypothetical Geometry Structure of the Gunung Padang Site.
Data were collected, and qualitatively were analyzed include interview data, observation data, field notes data, participant observations data, and the data of aerial photography using drones. All these data are used for triangulation so that the data will reinforce each other and then written in the form of scientific publications. The research results indicate that Gunung Padang site was structure of ^punden-berundak^, the place in which in ancient times was used as a place for worship by the community. This geometrical form of a structure does not resemble as a pyramid, but more like a pile of stones that includes terraces and piles.
