Mangrove Crab (Scylla serrata) is one of the marine commodities that have high economic value. The problem of mangrove crabs is the limited availab ility in nature, so this condition requires cultivation efforts to maintain the population in nature. Panipahan is one of the mangrove crab cultivation sites in Riau Province, which has been going on since 2013. This study aims to analyze the critical factors for the sustainability of mangrove crab farming businesses in the ecological, economic, institutional social and technological dimensions. Data collection techniques are carried out by observation, in-depth interviews and literature studies. The data analysis technique used is Multi-Dimensional Scaling (MDS) through the Rapfish approach. Informants in this study are experts consisting of cultivators, fisheries services and academics. The results of the analysis of the sustainability of the mangrove crab farming business on an MDS basis are in a less sustainable status with a score of 48.13. In the ecological dimension, the critical factor that affects sustainability is the source/availability of seeds. In the economic dimension, sustainability is influenced by business profit factors. In the institutional social dimension, the dominant key factors are the involvement of family members in the mangrove crab business and the potential for conflict. The dimension of technology that affects sustainability is technical assistance from the government and post-harvest handling. Operational steps that can be taken to obtain optimal results for mangrove crab cultivation business management in Panipahan are to carry out policies/programs related to key factors.
