2. Marsigit, Prof., Dr., M.A., Mathematics Department, Yogyakarta State University, Indonesia.
He is known as a mathematician and a philosopher of mathematics who has a great interest in ethnomathematics, which is a field of science that studies mathematics and its application (which is applied) to certain cultural groups. His interest in mathematics is proven through his writings and seminars where he is a resource person. Several scientific journals related to ethnomathematics published in the country use Marsigit's thoughts and writings as references. In 2018, Marsigit officially served as President of the Ethnomath Association. In addition to carrying out his role in the fields of research, community service, and higher education, as an expert in mathematics education, Marsigit is also active in writing mathematics books for primary and secondary education. Some of his books are written in Indonesian, others in English.
