PENGARUH PENAMBAHAN TEPUNG JAHE EMPRIT(Zingiber officinale var. Amarum) PADA PAKAN TERHADAP PERTUMBUHAN DAN DAYA HIDUP IKAN NILA (Oreochromis niloticus)

Abstract

Tilapia (Oreochromis niloticus) is a type of fish that has high economic value.
Cultivation is determined by two factors: fish disease and growth. Among the results of
immunostimulant studies added in the diet can increase the nonspecific immune response as well
as increase the growth of fish, immunostimulant ingredients are one of ginger emprit (Zingiber
officinale var Amarum). This study aims to analyze the effect of the addition of ginger flour
emprit to growth rate, survival rate and feed conversion ratio of tilapia fish. The research method
used was Completely Randomized Design (CRD) consisting of 4 with 3 replications, namely:
treatment A = 5, B = 7.5, C = 10 g/kg of feed and control (no addition of ginger). The main
parameters observed were specific growth rate, absolute weight, survival rate and feed
conversion ratio. The supporting parameters are water quality consisting of temperature, pH and
DO. Analysis of the data using ANOVA if influenced by further Tukey test (p <0,05). The
results showed that the best growth in this study was in treatment with a dose of 7.5 g/kg of feed
with an absolute weight of 5.40 ± 0.34 g, a specific growth rate of 2.41 ± 0.08%/day, survival
rate that is equal to 90 ± 0,0%, and feed conversion ratio of 3.6 ± 0.15 g.
