Abstract

The main issues of seaweed cultivation Kappaphycus alvarezii currently outline are: (a) declining production due to ecological pressure of marine waters, (b) sustainability protection and cultivation business income, and (c) sea space utilization conflicts. To anticipate these problems, one of the strategic alternatives that can be done is to conduct ecologically, technically and socially economically viable cultivation through the utilization of pond land located in coastal land area through intensive cultivation system. This study aims to determine the rate of specific growth (LPS) K. alvarezii. Cultivation conducted in April to May 2018 for 42 days in  ponds. The number of expanses 10 spans, each span of 120 dots is 25 cm. with a weight of 100 g per point. During cultivation fertilization, water change, aeration and water quality control. Weights and biomass are measured weekly by the sampling method in each different stretch group. Data were analyzed using descriptive analysis. The results showed average LPS obtained is 3.38%/day. Water quality during cultivation is within the range that K. alvarezii can tolerate. Keywords: Relocation of cultivation, Ponds, Intensive System, Kappaphycus alvarezii, Specific Growth Rate (LPS)
