Abstract
the study has been conducted on the analysis of environmental feasibility of one of the uninhabited islands in the city of Batam, the island of Seloko. Seloko Island is an island that will be used as a shipping industrial estate. This research was conducted to determine the environmental baseline and the feasibility analysis of the Seloko Island coast before becoming a shipping industry area. The analysis was carried out by observing and conducting laboratory tests on water, sediments, mangrove vegetation, seagrass and coral reefs in the island. Based on the results of laboratory tests conducted on island water, the form of DO concentrations ranged from 6.5 to 73.3 mg/l; PH ranged from 7.5 to 7.9; Salinity average was 33,3 o/oo and temperatures ranged from 29.8-30.4 OC, while the results of laboratory testing of the dominant sedimentation of fine sand and coarse sand ranged from 118,196 gr/m2 – 189,34 gr/m2. Furthermore, based on observations on the diversity of mangroves, there are several types of mangroves in Seloko Island such as Avicennia alba, Sonneratia alba, Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa, Bruguiera gymnorrhiza, Xylocarpus granatum, and Nypa fruticans. The results of observations of seagrass cover using species Enhalus acoroides reveal that the condition of seagrass is not good ranging between 0 - 2.75%. On the other hand, the results of observations on coral reefs show that the condition of corals is not good which ranges from 0 to 0.67%.
