摘要：This study aims to uncover and build Baitul Maal wa Tamwil (BMT) with the cooperative legal culture to eliminate rent systems in traditional markets. The research questions are: how is the existing condition of BMT legal culture and how to build new construction of cooperative legal culture on BMT. This research uses qualitative type of research, a traditional non-doctrinal legal research, with a socio legal approach. The results showed that the business of borrowing money with a very high interest or the practice of loan sharks until now is still rampant in a number of traditional markets, the practice of loan sharks in the form of Plecit Bank or UcekUcek Bank remains in demand by the public. The existence of Baitul Maal wa Tamwil (BMT) apparently has not been able to play a optimal role in traditional markets. BMT is under the legal umbrella of cooperatives in practice apply to the Bank. such as borrowing money with a high margin, there is still a guarantee, a long process and consider the customer as a banking customer, not as a member, so there is no cultural closeness. For this reason, it is necessary to establish a legal culture in BMT that has a cultural spirit and cooperative spirit, namely mutual cooperation and togetherness, from members to members. all the benefits of the cooperative achieved by the group, can always be felt directly by all members.
