This study uses interviews as a research instrument to find out what factors affect the effectiveness of musharakah financing in empowering micro small business of BMT entrepreneurs in the Special Region of Yogyakarta. Entrepreneurs from two BMT in Yogyakarta had been interviewed. The results showed that BMT musharakah financing played an important role in the business development of Micro and Small Business, especially in terms of increasing business capital, easy access to take financing and a small amount of instalments. In addition, musharakah financing is effective in encouraging MSE empowerment, to increase the amount of merchandise inventory, add new types of products, expand businesses and add new equipment for business facilities. This study limits the ability to generate findings to a larger population of small-micro enterprises which obtain shariah financing from Islamic microfinance institutions (Baitul Maal Wat Tamwil) in Indonesia.
