Abstract Indonesia is a maritime country has the most islands in the world with many islands in Indonesia, where between one island to the other islands are separated by the sea. Indonesia has a long coastline that is 95.181 km, of which about three-quarters (5,8 million km2) of marine waters of Indonesia is composed of the sea coast, seas, bays and straits. North Jakarta coastal areas are being reclaimed and is seen disturbing the balance three aspects of coastal areas, such as environmental, social, and economic, as well as coastal zone management strategy is needed. Analysis of North Jakarta coastal zone management with system dynamics models to show the relevance of social aspects (Level Fishermen welfare), economic aspects (Revenue fishermen) and environmental aspects (Area of ponds, mangrove forests, and total of fishing). Models are designed to validate with the values obtained, AME (pond area) = 49,54%, AME (Mangrove) = 5,60%, and AME (total of fishing) =
5,64%. Simulation models has done up in 2019. The impact on the economic aspect is the decrease of fishermen's income from Rp. 5.000.000,00-Rp.10.000.000,00 to around Rp 2.000.000,00-Rp.3.000.000,00. The impact on the social aspect is the reduced level of welfare. The impact on the environmental aspect is the reduction in a mangrove area, and accompanied by an increased area of the pond. The design of two scenarios on the model of intervention to resolve the existing problems, the first intervention scenario by using of technology and the second intervention scenario is a combination of using technology and restoration of mangrove forests program. Obtained in the simulation results, that both scenarios can show the desired trend in the future.
