Abstract

Utilization of waste water from catfish farming as Spirulina platensis medium has direct impact on fish farmer income and lead to loss of environmental pollution. The purpose of this study was to determine the best fertilizer compotition that was made from technical fertilizer and waste water of cat fish farming. This experimental was conducted at Aquaculture Laboratory, Faculty of Agriculture, Sriwijaya University. It used complete randomized design (CRD) method which had five treatments and three replications, the waste water from catfish pond (Po), waste water from catfish pond + 25% technical fertilizer (Pj), waste water from catfish pond + 50% technical fertilizers (P2), the waste water from catfish pond + 75% technical fertilizers (P3), the waste water from catfish pond + 100% technical fertilizers (P4). The parameters of this study were maximum density, specific growth rate of S. platensis, water qulity and economical analysis. The results showed that the best maximum density of S. platensis was P3 about 3.98 g L'1, and growth rate was equal to 2.80% day'1. The most significant parameter of water quality was ammonia which decreased until 82.78%. Besides, it was more beneficial than others based on Return Cost Ratio (R/C ratio) and Benefit Cost Ratio (B/C ratio) which were 3.66 and 2.66 respectively.
