The thing that can bridge culture and mathematics is ethnomathematics. This study aims to describe the philosophy of Lopo , describe ethnomathematics activities and mathematical concepts in Lopo in Tamkesi Traditional Village and its integration in mathematics learning. This study is a qualitative study with an ethnographic approach, which was conducted in Tamkesi Traditional Village, Biboki Selatan District, North Central Timor Regency, with 3 informants. The research instruments are the main instrument, namely the researcher and supporting instruments, namely observation guidelines, interview guidelines and documentation.
