Mudharabah Musytarakah in Ijarah Practice

This research investigates the implementation of mudharabah musytarakah in ijarah practices within fish management cooperation in Nagari Rambatan, Tanah Datar Regency. The study addresses three main questions; How is fish management cooperation practiced in Nagari Rambatan?, How is leasing applied within this cooperation?  And how is the mudharabah musytarakah contract implemented in these leasing practices. This field research employs a qualitative approach, utilizing interviews and documentation for data collection. Informants include the fish management group, pond owners, and tenants. Data sources comprise both primary sources (direct participants) and secondary literature (books, journals, and previous studies). Source triangulation is used to ensure data validity. Findings reveal that a mudharabah musytarakah partnership exists between the fish management group and pond owners. The management group bears the cost of fish seeds, feed, and pond maintenance. Profit-sharing is informal—no fixed percentage is determined at the contract stage; instead, the group shares profits with the pond owner based on realized outcomes. In terms of ijarah, the fish management group leases pond space to tenants. The tenant contacts the group’s leader directly, and the leased pond area has been previously agreed upon between the management group and the pond owner. From the rental income, the group pays IDR 200,000 to the pond owner. Thus, the implementation of mudharabah musytarakah and ijarah is evident through collaborative agreements and shared responsibilities, despite informal practices, indicating a unique hybrid application of Islamic economic contracts in local fishery management.
