Ultra-Micro-Business Algorithm: Village Economic Metabolism in the Coastal Area

Indonesia is an archipelago country having two-third of the ocean, which encourages an GDP increase through the development of marine products and fisheries, but in reality, coastal areas have not been able to utilize their resources, which leads to five percent of GDP compared to the potential of 1.3 times GDP or 130 percent. However, today in some coastal areas in Indonesia ecological threats damages the environment, ecosystems, flora, and fauna, which leads to climate change and loss of productive land due to anthropogenic behavior. Marine management is to ensure the sustainability of fish resources and the environment as the carrying capacity of marine and fisheries communities, especially in coastal areas, ultimately produces economic resources sourced from the resources and biodiversity. This chapter focuses on the coastal area of Tangerang Regency of Indonesia that is actually the gateway to Indonesia because it is adjacent to Jakarta, the capital of Indonesia. It is important to initiate a coastal area realignment program with the concept of redesigning society by involving all stakeholders through a Social Network Analysis approach (SNA).
