Spatial Planning for seaweed cultivation
Limited study information in determining the location of seaweed cultivation
Effort can be madeUtilize remote sensing
Estimation of a wider potential area
Pressured by the development

Figure 6. Suitable Area of Seaweed Cultivation in Serangan Island
Conclusion▪ The season is one of the factors that influence oceanographic conditions.
▪ The sea surface temperature in the coastal waters of Serangan Island during the rainy season is warmer than during the dry season. The resulting salinity value is inversely proportional to sea surface temperature.
▪ Total suspended solids in the rainy season is more optimal for seaweed cultivation, while dissolved oxygen in both seasons is low for seaweed cultivation.
▪ The suitability of the seaweed cultivation area in the rainy season is dominated by quite suitable area of 616 Ha and suitable 1,52 Ha which is located in some northern and southern water areas, namely, grid G12, H13, I5, I13, and B2.
▪ In the dry season there are suitable areas covering an area of 223 hectares located in the northern, eastern, southern and southwestern parts of Serangan Island (31 grid), quite suitable for 392 hectares (72 grids), and unsuitable for 2,52 hectares located in part east and west grids B9, B10, E8, F9, and G6.
▪ The relatively clear and sandy water conditions also indicate that the waters on SeranganIsland are classified as suitable for seaweed cultivation.
