ENZIM MANANASE DAN FERMENTASI JAMUR UNTUK MENINGKATKAN KANDUNGAN NUTRISI BUNGKIL INTI SAWIT PADA PAKAN IKAN NILA BEST (Oreochromis niloticus)

Abstract

Palm kernel meal is CPO (Crude
Palm Oil)-by product are potentially as
an alternative raw material fish feed. This
research aims to know the influence of the
enzyme mananase and mold fermentation
to improve the quality of palm kernel over
the extent of the digestibility of oreochromis
BEST. This study used a Randomized
Complete design of experiment method
(RAL) with seven treatments and three replicates
each. BEST tilapia with weights 25
± 1.57 gram put in 21 60x40x40cm3 sized
aquarium. Test feed was given for 15 days
as a mortgage with a frequency three times
a day. The results showed that the total digestibility
(56,74%) and protein digestibility
(82,38%) resulting from the best treatment
of palm kernel with the addition of
mananase enzyme and fermentation of the
mold Rhizopus oligosporus and for carbohydrate
digestibility (60,72%) and energy
digestibility (71,82%) obtained the best result
from the treatment of palm kernel with
the addition of mananase enzyme and fermentation
of Trichoderma reesei mould.
