Abstract

Lobster, one of the high values sea-cage culture commodities in Indonesia, has some specific
requirements of life environment. However, there haven’t been any studies that specifically identify these potentialites. Until today it is only 3.50 ha out of 526.86 ha of these that have been utilized. This study aims to map the marine suitability environment for lobster cultivation in Ekas Bay, using remote sensing and GIS approaches. The requirement parameters maps for lobster marine suitability, includes oxygen levels (DO), nutrition, salinity, temperature, depthness, pH, and water clearence which were extracted from Landsat 8 imagery. Using GIS, a model was developed to integrate those maps with marine environment secondary maps, water laboratory analysis, and other information from interview result with the local farmers. The result showed that lobsters live in the temperature environment between 200 and 250C while the water depth 100 m. Laboratory analysis resulted pH value of above 7 in average, DO from 5-8 mg/L, and salinity level from 28 to 35 ppt. In summary, the integration of remote sensing and GIS approaches were able to identify the common parameter that support the environment suitability for lobsters which can be formulated as a standard of marine environment suitability mapping.
