Abstract


Mangrove is the only ecosystem that grows and develops in the coastal area formed by the interaction of biota, landscapes, waterways, and atmospheric environments. This study was conducted to analyze the mangrove forest vegetation to create a simulation of the root system of Rhizophora apiculata related to its ability in the process of hydrodynamic fluid in Lompo village, subdistrict Awangpone, district Bone, South Sulawesi. Criteria were used as reference model about five years old with a height of about 2 m. The measured variable is the height and diametr of the stem and root. The parameters simulation are the average speed of sea level, the dynamic pressure and the drag coefficient Bone Bay. Based on the results of the study, the average speed of sea water and the dynamic pressure is at its lowest-density solid natural cropping pattern, while the highest are in the cropping pattern density parallel sparse. The coefficient of drag, which is the highest in the cropping pattern natural solid density, while the lowest are in the cropping pattern density parallel sparse. Maintenance of mangrove areas and the use of pond systems silvofishery can be improved so that the socio-economic value of mangrove forests can be achieved with the maximum.
