%T EFEKTIVITAS PEMBERIAN MIKROKAPSUL PROBIOTIK 
TERHADAP KOMPOSISI BAKTERI PADA USUS 
IKAN KERAPU MACAN Epinephelus fuscogutattus (Forsskal, 1775)
%X Penelitian ini bertujuan untuk mengetahui pengaruh pemberian mikrokapsul 
probiotik terhadap komposisi bakteri pada usus ikan Kerapu Macan (Epinephelus 
fuscogutattus).Rancangan penelitian yang digunakan adalah Rancangan Acak 
Lengkap (RAL) dengan lima perlakuan dan tiga ulangan, yaitu perlakuan K+ 
(Pemberian pakan dengan probiotik tanpa mikrokapsul), K- (Pemberian pakan 
tanpa penambahan probiotik), A (Pemberian mikrokapsul probiotik dengan dosis 
1g/kg pakan), B (Pemberian mikrokapsul probiotik dengan dosis 2g/kg pakan), 
dan C (Pemberian mikrokapsul probiotik dengan dosis 3g/kg pakan). Parameter 
yang diamati meliputi viabilitas sel bakteri Bacillus sp. D2.2, komposisi bakteri 
pada usus Kerapu Macan, kelimpahan bakteri asam laktat dan kelimpahan 
Bacillus sp. D2.2. Hasil penelitian menunjukkan bahwa terdapat pengaruh 
pemberian mikrokapsul probiotik terhadap komposisi bakteri pada usus Kerapu 
Macan. Mikrokapsul probiotik mampu mempengaruhi viabilitas bakteri probiotik 
dan kelimpahan bakteri asam laktat.

This study was aimed to determine the effect of probiotic microcapsules on the 
bacterial composition on tiger grouper (Epinephelus fuscogutattus) intestine. The 
experimental design was used completely randomized design with five treatments 
and three replications, namely K + (Fed with probiotics without microcapsules), 
K- (Fed without the addition of probiotics), A (Fed with 1 g/kg microcapsules 
probiotics dose of feed), B (Fed with 2 g/kg microcapsules probiotics dose of
feed), and C (Fed with 3 g/kg microcapsules probiotics dose of feed). The 
observed parameters were probiotic cell viability, bacterial composition on tiger 
grouper intestine, abundance of lactic acid bacteria and abundance of Bacillus sp. 
D2.2. The results showed that probiotic microcapsules had the effect on bacterial 
composition in the intestines of tiger grouper. Probiotic microcapsules could 
affect the viability of probiotic bacteria and also affect the abundance of lactic 
acid bacteria.
