Pengaruh Penambahan Enzim Phytase Dosis Berbeda Pada Pakan Terhadap Pertumbuhan Dan Kelulushidupan Ikan Nilem (Osteochilus Hasselti) Dengan Sistem Resirkulasi

---

ABSTRACT
The purpose of this study was to determine the best dose of phytase
enzyme in commercial feed to increase the growth of nilem fish (Osteochilus
hasselti) with a recirculation system. This study used an experimental method
with a one-factor Completely Randomized Design (CRD) with five treatment
levels and three replications. The treatments were: P0 (without phytase enzyme),
P1 (phytase enzyme 0.5 g/kg feed), P2 (phytase enzyme 1 g/kg feed), P3 (phytase
enzyme 1.5 g/kg feed) and P4 (phytase enzyme 1.5 g/kg feed), phytase 2 g/kg
feed). The results showed that the addition of the phytase enzyme in the feed
showed a significant effect (P0.05) on the survival rate. The results showed that the phytase enzyme
with different doses in feed with a recirculation system had a significant effect on
nilem growth, absolute weight, absolute length, specific growth rate, feed
conversion ratio and feed digestibility. The best treatment was P4 (phytase
enzyme 2 g/kg feed). ) with an absolute weight growth of 4.69±0.45 g, an absolute
length growth of 2.90±0.01 cm, a specific growth rate of 3.93±0.19%, an FCR of
1.19±0.01%, and survival rate of 100±0.00%. The digestibility value of nilem fish
feed is 71.26% and protein digestibility in nilem fish is 87.15%. Water quality
parameters during the study still supported the temperature ranged from 27.2-
28.8˚C, water pH ranged from 6.1-7.2, dissolved oxygen content (DO) ranged
from 4.5-6.5 ml/L and ammonia ranged from 0.00057-0.00195 mg/L.
