3.7. Coastal Ecosystem Development 3.7.1. Resort Tourism Area
Land suitability for resort tourism area is based on tourism suitability criteria. Land suitability matrix used was referring to criteria that have been done
by Bakosurtanal 1996, in which resort tourism was related to activities on the beach building, such as: swimming pool, garden, sunrisesunset and other
activities to see of beauty of the sea. Table 3.4 is shown requirement of land suitability for resort tourism activities. These requirement is not absolutely can be
implemented to any location, but it is depend of location natural characteristics. For this case, the resort tourism requirement above is suitable for location in
Indonesia.
3.7.2. Marine or Aqua Cultivation
Marine or aqua cultivation that will be developed are “keramba jaring apung”, seaweed, and fishpond cultivation. Tables 3.5, 3.6, and 3.7 showed the
condition that have to be considered for marine aqua cultivation.
