        abstract = {Probiotik berpengaruh dalam meningkatkan pertumbuhan ikan. Namun probiotik 
umumnya tidak mampu bertahan hidup ketika melewati lambung dan saluran 
pencernaan. Dengan teknik mikrokapsul probiotik, diharapkan probiotik yang 
dicampur ke dalam pakan tidak rusak saat melewati saluran pencernaan. Tujuan 
dari penelitian ini adalah untuk mempelajari peningkatan pertumbuhan ikan kerapu 
macan yang diberi pakan mengandung mikrokapsul probiotik Bacillus sp. D2.2 
dengan dosis berbeda. Hasil penelitian menunjukkan bahwa pemberian pakan 
dicampur mikrokapsul probiotik dapat meningkatkan pertumbuhan ikan kerapu 
macan. Berikut hasil pengamatan tertinggi yaitu pertumbuhan berat mutlak (23,8 {$\pm$} 
0,7) gram, laju pertumbuhan harian (1,35 {$\pm$} 0,04) \% per-hari, rasio konversi pakan
(FCR) (1,3 {$\pm$} 0,1), kelangsungan hidup (83 {$\pm$} 2,9) \% dan kecernaan protein 90,56 
\% Sedangkan nilai terendah yaitu pada perlakuan kontrol. Hasil uji anova 
menunjukkan bahwa pemberian mikrokapsul probiotik berpengaruh nyata terhadap 
pertumbuhan berat mutlak, laju pertumbuhan spesifik dan rasio konversi pakan 
dibandingkan dengan perlakuan kontrol.

Probiotics have an effect on increasing fish growth. However, probiotics are 
generally unable to survive when passing through the stomach and digestive tract. 
With the probiotic microcapsule technique, it is expected that probiotics mixed into 
the feed will not be damaged as they pass through the digestive tract. The purpose 
of this study was to study the increase in growth of tiger grouper fish fed with 
probiotic Bacillus sp. D2.2 with different dosages. The results showed that feeding 
with probiotic microcapsules mixed could increase the growth of tiger grouper fish. 
The following are the highest observations, namely absolute weight growth (23.8 {$\pm$} 
0.7) grams, specific growth rate (1.35 {$\pm$} 0.04)\% /day, feed covertion ratio (FCR) 
(1.3 {$\pm$} 0.1) ), survival rate (83 {$\pm$} 2.9)\% and protein digestibility 90.56\% while the 
lowest value is in the control treatment. Anova test results showed that the 
administration of probiotic microcapsules significantly affected the growth of 
absolute weight, daily growth rate and feed covertion ratio compared to control 
treatments.
