Abstract
The Tidung Island in Kepulauan Seribu District is a tourist destination for both domestic and foreign tourists. However, not all residents of Tidung Island work in the tourism sector. Some work as fishermen. In 2016, local governments developed seaweed cultivation (Eucheuma cottonii) which made some residents switched jobs to seaweed farmers. This study aims to determine which areas are oseanographically appropriate and have potential as a seaweed cultivation development area. The research method use variables of oceanography in the form of substrate type, protected, temperature, depth, current speed, salinity, and pH. The cultivation variable consists of labor, technology, and management. To determine the direction of development, tourism variables which being used consist of distance from tourist sites and the number of supporting facilities. The analysis uses Geographic Information System (GIS) technique and scoring method. The results show in the northern Tidung Island waters are suitable for seaweed cultivation from the point of view of oceanography. However, the development potential is only in U2 segment, which is support by high production quantities, long distance from tourism object, and low number of accommodation makes it potentially to be developed area.
Highlights
Indonesia is an archipelago geographically with two thirds of the vast ocean bigger than the Mainland. This can be seen by the existence of the shoreline in nearly every island in Indonesia (± 81,000 km) which made Indonesia ranks second after Canada as country that has the longest coastline in the world [1]
Tidung Island is located at position 5o 79’ - 5o 80' south latitute and 106° 47' - 106° 51' west longitude
This study focused on the coastal Tidung Island
Summary
Indonesia is an archipelago geographically with two thirds of the vast ocean bigger than the Mainland. This can be seen by the existence of the shoreline in nearly every island in Indonesia (± 81,000 km) which made Indonesia ranks second after Canada as country that has the longest coastline in the world [1]. Seaweed was commonly used as fertiliser and food for animals or people, during food shortages. In modern times, it has many applications in the cosmetic, food processing, biomedical, pharmaceutical and printing industries and as a feedstock for biofuels and anaerobic digesters [3]
