Abstract

Aquaculture is one of the steps taken by the DKI Jakarta Provincial Government to manage fishery resources. Kepulauan Seribu, in recent years, has experienced a decline in the production of fresh fish; therefore, the cultivation of the Grouper floating system has become an alternative solution. Successful breeding is supported by site selection due to assembling on the terms of Groupers life that includes water quality and oceanography. Water quality parameters include salinity, pH, dissolved oxygen, and oceanographic parameters, that is, sea surface temperature, depth, and current velocity. The method of analysis in this research is descriptive spatial based on the overlay results of Landsat 8 image data processing and in situ measurement data during the field survey. The analyst statistics was descriptive to analyze the relationship between the region of conformity with the results of Grouper fish production. The results of the statistical and spatial analysis found that the location of floating net cages in the Kepulauan Seribu in the class is very appropriate and appropriate. Meanwhile, the relationship between regional suitability and Grouper production in the Kepulauan Seribu is weak because production is related to other driving factors.
