Effect of Difference Distance Depth Against Seaweed Kappaphycus alvarezii Growth and Gynecology Carragenan In Pelabuhan Ratu Gulf waters . This research was conducted in the coastal village of Kertajaya Pamipiran Sukabumi District of Simpenan for planting seaweed Kappaphycus alvarezii and Biotechnology Laboratory Marine Fisheries Padjadjaran University in August-October 2013. This study aims to determine the growth rate and the content of carrageenan seaweed Kappaphycus alvarezii types at various depths . The method used in this study is an experimental method with the difference that the depth distance of 1 meters, 2 meters, and 3 meters . Parameters measured were growth rate , and the carrageenan content of water quality such as temperature , salinity , pH , brightness and speed of flow . Analysis of data on the growth of seaweed variables each treatment used analysis of variance followed by a Duncan test . The results showed that the average value of the highest growth was obtained at a depth of 1 meters at week six is the average weight of 529 grams and extraction of carrageenan obtained the highest value at a adepth of 1 m at 24.11 % . Duncan test results of analysis of variance showed that the treatment had a significant influence on the rate of growth . The results of the average specific growth rate of seaweed Kappaphycus alvarezii the highest obtained at a depth of 1 meter is atweek six with a standar deviation (45,22) and the coefficient of 0,977577 manifold so it lokks significantly different at the level of 1% . While the range of water quality parameters obtained during the feasibility study is still in the range 29 - 310C temperature , pH 8-8.5 g / L , the brightness of 2-3 m , salinity 29-30 ppt,and its current velocity is 34-40 cm/sec. .
