Abstract
South Sumatera has a very large shrimp pond, most of them were abandoned and untreated. The caused is the diseases such as white spot resulted in crop failure. It requires the effort in order to optimize and utilize the pond area. One of them by cultivating the Gracilaria sp seaweed which has a high economic value, easy to cultivate and tolerant to environmental changes. This study aims to analyze the parameters of water, analyze the growth rate of Gracillaria sp seaweed with Floating Net method. The results showed that the weekly growth of Gracilaria sp in the first week was highest in the fifth MFN with a weight of 5,540 grams and the lowest on the second MFN with 5,425 grams. At the second week the highest growth of third MFN (6,021 grams) and the lowest on fourth MFN (5,797 grams). On the third week, the highest growth of third MFN (6,625 grams) and the lowest fourth MFN (6,380 grams). On the fourth week, the highest growth of third MFN (6,950 grams) and the lowest on second MFN (6,864 grams). On the fifth week, the highest growth of first MFN (7,450 grams) and the lowest third MFN (7,010 grams) and on the sixth week, the highest growth of sixth MFN (8,215 grams) and the lowest third MFN (7,120 grams). The highest growth rate was at sixth week gain weight of 895 grams (sixth MFN). While the lowest was at fifth week with the addition of weight amounted to 60 grams (third MFN). The highest average growth rate actually occurred at the third week with the addition of average weight of 3,653 grams and the lowest was at the fifth week (2,193 grams). The highest absolute growth was found in the sixth MFN with a final weight of 8,215 grams and an absolute growth rate of 3,215 grams. While the lowest weight on the third MFN with weight 7,120 grams and growth rate of 2,120 grams. There was an increase of 1.424 – 1.643 times the weight of the initial weight of planting. The daily growth rate ranges from 0.84515 - 1.189% /day. The DGR value is highest in the 6th of MFN with the value of 1.18922 and the lowest was in the 3rd of MFN of 0.84515% days. All of the methods (MFN) show DGR results <2% /day. Parameters of pond water are still in the range for the cultivation of Gracilaria sp.
