Abstract
This study aimed to understand the antioxidant activities in Lemna sp. and its influence on Nile tilapia performance. This study was performed at the Chemical Laboratory and Aquaculture Laboratory in Universitas Padjadjaran during the period of March to July 2018. This was an experimental study using Completely Randomized Design (CRD) with 5 treatments and 4 repetitions. In Treatment A (Feed Without Lemna sp), B (Commercial feed + 25% Lemna sp. extract from IC50), C (Commercial feed + 50% Lemna sp. extract from IC50), D (Commercial feed + 75% Lemna sp. extract from IC50), E (Commercial feed + 100% Lemna sp. extract from IC50). Data collected in this study were analyzed using Analysis of Variance with a confidential level of 95%, followed by Duncan’s multiple range test. In vitro extraction was performed on 772 grams of dried lemna with 1,1–diphenyl-2-picryllhydrazil (DPPH) testing using UV-Vis Spectrophotometry. The IC50 value of the mixing dose with commercial feed was then calculated. Ten 9-10 cm Nile tilapia fish was maintained in aquariums for 28 days. The amount of feed provided was 10% of the total biomass of the fish. Results showed that the IC50 value of lemna extract was categorized as quite strong, i.e. 54.517 ppm. The highest daily growth rate, survival rate, and blood cell count was in Treatment B that is 2.36%, 100%, 6.995.000 cells/mm3 for red blood, and 804.000 cells/mm3 for leucocytes.
