Abstract: Bima Bay is a socio-ecological system (SES) with semi-closed water, located between 2 local governments, encompassing Bima Regency and Bima City. The total population in the coastal area was 185419 and 190736 people, in 2016 and 2018, respectively, featuring a 1.03% increase. However, about 5097 people (0.02%) of Bima Bay depend on the fisheries sector as a source of livelihood. The purpose of this study, include: (1)mapping the SES of Bima Bay, adopted from the conceptual model in the socio-ecological system; (2) obtaining quantitative data using network analysis between the socio-ecological system components. The analysis tools used are the mapping of the SES conceptual model and social network analysis (SNA). The results based on the highest degree are the following: fisheries business - 17 degrees; fish - 14 degrees; shrimp - 12 degrees; and local regulation - 11 degrees. The highest betweenness value (41.98) was observed in local regulation and number of visits, while the value for market and fisheries business was 39.3. The lowest value (2.06) was recorded for fish and shrimp. Therefore, 6 groups of relationships were established in the SES of Bima Bay, on the basis of cluster or community detection.
