Abstract

Nannochloropsis sp. One type of phytoplankton that is very abundant in the waters ecosystem of the Mangrove Lampung Center (LMC), so that Nannochloropsissp. has the potential as a natural feed in aquaculture. Availability of .natural feed stocks continuously is often a problem in aquaculture, so the availability of feed stock in powder form is the answer to these problems.This study aims to make Nannochloropsis sp. Powder isolated from nutritious LMC aquatic ecosystems based on its fat content.The making of powder began with a semi-mass scale Nannochloropsissp culture using a combination of fertilizer namely 40 ppm Urea farming, 20 ppm ZA and 5 ppm TSP, then 175 ppm NaOH solution was given to the culture media at the optimum growth to made a paste and finally the paste is dried to become powder.The treatment in this study was the drying temperature which included a temperature of -50°C, 20°C, 30°C, 50°C and 70 “C each treatment was repeated 4 times. Analysis of powder quality based on protein content analyzed by proximate analysis.The data obtained were analyzed using the Analysis of Variance (ANOVA) method, if the results were obtained that were significantly different, it would be carried out with the Least-Significant Difference test (LSD) level o = 0.05. The results showed that the highest protein content produced at a drying temperature of -50°C was 8.89 1; 019% and 70°C was 8.07 i .69%, and the protein content of the two treatments was significantly different from the protein produced at drying at 20 °C, 30°C, and 50°C (p <0.05). While the drying content of -50°C and 70°C the protein content produced was not significantly different (p = 0.250).
