dc.description.abstract | Teknologi bioflok telah diketahui dapat menurunkan kadar amonia pada
media pemeliharaan budidaya sistem intensif dan probiotik Bacillus NP5R
telah
diketahui dapat meningkatkan pertumbuhan dan tingkat kelangsungan hidup
melalui peningkatan efisiensi pencernaan dan kesehatan ikan. Penelitian bertujuan
mengevaluasi penambahan probiotik Bacillus NP5R pada sistem bioflok dalam
meningkatkan kinerja pertumbuhan dan status kesehatan benih lele Clarias sp..
Penelitian menggunakan rancangan acak lengkap (RAL) dengan tiga perlakuan
dan tiga ulangan, yaitu ikan dipelihara tanpa aplikasi bioflok dan penambahan
probiotik Bacillus NP5R
(K), ikan dipelihara dengan sistem bioflok (BF), dan
ikan dipelihara dalam sistem bioflok dengan penambahan probiotik Bacillus NP5R
(BFP). Larva lele dengan panjang rata-rata 0,83±0,00 cm dan bobot rata-rata
0,02±0,01 g dipelihara dengan padat tebar 300 ekor/akuarium selama 30 hari.
Parameter yang diamati meliputi pertumbuhan panjang mutlak, laju pertumbuhan
harian, rasio konversi pakan, koefisien keragaman, kelimpahan bakteri Bacillus
NP5R
, total eritrosit, total leukosit, kadar hemoglobin, kadar hematokrit, dan
tingkat kelangsungan hidup. Hasil penelitian menunjukkan bahwa penambahan
probiotik Bacillus NP5R dalam sistem bioflok dapat meningkatkan laju
pertumbuhan 5%, tingkat kelangsungan hidup 15%, dan status kesehatan benih
lele yang menunjukkan hasil terbaik dibandingkan perlakuan lainnya. Penerapan
sistem bioflok dengan penambahan Bacillus NP5R diharapkan menjadi alternatif
solusi untuk mengurangi limbah amonia pada budidaya ikan lele. | id |
dc.description.abstract | Biofloc technology has been known to reduce ammonia levels in
aquaculture’s intensive system maintenance media and the probiotic Bacillus
NP5R
has been known to increase growth and survival rates through improved
digestive efficiency and fish health. This study aimed to evaluate the addition of
probiotic Bacillus NP5R
in the biofloc system in improving growth and health
status of catfish juvenile Clarias sp.. This study used a complete randomized
design (RAL) of three treatments and three replications, namely fish reared
without biofloc system and without addition of probiotic Bacillus NP5R
(K), fish
reared in a biofloc system (BF), and fish reared in a biofloc system with the
addition of probiotic Bacillus NP5R
(BFP) within 30 days of treatment. The larvae
that used had an average length of 0,83±0,00 cm and an average weight of
0,02±0,01 g with a stocking density of 300 individuals per aquarium. Parameters
observed during the study included absolute length growth, daily growth rate, feed
conversion ratio, coefficient of diversity, abundance of Bacillus NP5R bacteria,
total erythrocytes, total leukocytes, hemoglobin levels, hematocrit levels, and
survival rates. The results showed that the addition of the probiotic Bacillus NP5R
in the biofloc system can increase the growth rate by 5%, survival rate by 15%,
and the health status of catfish juvenile which showed the best results compared to
other treatments. The application of the biofloc system with the addition of
Bacillus NP5R
is expected to be an alternative solution to reduce ammonia waste
in catfish farming. | id |
