This research was purposed to determine the effective dose of meniran and garlic flour in feed by repelleting method for preventive and curative efficacy to the infection of Aeromonas hydrophila in catfish. The treatment tested were eight different dosages of garlic and meniran meals (2:1). Those four dosage used to preventive treatment namely A (0.1%), B (1.1%), C (2.1%), and D (3.1%), the other four used to curative treatment namely E (0.2%), F (2.2%), G (4.2%), and H (6.2%). The preventive treatments were given for two weeks before challenging test. The curative treatment was performed on 2nd–8th day after challenging test. Challenging test was carried out by intramuscularly injecting of 0.1 mL A. hydrophila (108cfu/mL) into the fish. Parameters observed were feeding response, growth rate, survival rate, clinical symptoms, wound healing, and organs morphology. The result showed that the survival rate of preventive treatment was 40±40% for A and B, 60±20% for C, and 20±20% for D. The survival rate of curative treatment was 33.33±11.55% for E, 46.67±11.55% for F, 33.33±11.55% for G, and 26.67±11.55% for H. The results indicated that the preventive treatment was more effective than the curative treatment, presumably because the immunostimulatory activities on preventive was better than curative.

The use of antibiotics for controlling of luminous vibriosis caused by Vibrio harveyi is restricted now, because it induces antibiotic-resistant bacteria and leave residue in shrimp’s body. An alternative solution that can be done to treat the disease is by using applications of probiotic, prebiotic, and synbiotic. The aim of this research was to examine the effect of probiotic, prebiotic, and synbiotic on the survival rate and growth of Pacific white shrimp against V. harveyi infection. Feed as a treatment was supplemented with probiotic 1%, prebiotic 2%, and probiotic 1%+prebiotic 2% (synbiotic). Shrimps feed without supplementation of probiotic and prebiotic was used as a control treatment. The shrimps were maintainedin the aquarium (60×30×35 cm3) with a density of 40 shrimps/40 L and an average weight of 0.4±0.1 g. After 30 days of feeding treatment, the shrimp was challenged by immersion method with V. harveyi solution containing 106 CFU/mL. The results showed that before challenge, synbiotic feed treated shrimp has a growth rate (5.89%), feed conversionrate (1.21), and a high survival rate (80%). After challenge, survival rate (83.33%) of shrimp fed diet supplemented with synbiotic was higher than prebiotic (51.67%) and positive control (31.67%).

ABSTRACTWhite spot syndrome virus (WSSV) is the most dangerous shrimp pathogen and give a very bad impact to the shrimp industry in many countries, including Indonesia. Furthermore, the vaccine usage is less effective since the local WSSV suspected to have some mutation and have differences in sequence from the one that used for recombinant vaccine production so far. Therefore, it is necessary to produce recombinant vaccine for immunization of local shrimp according to WSSV isolates from Indonesia. Viral protein 19 (VP19) is an important WSSV envelope proteins because of its involvement in the systemic infection of shrimp, so it can be developed as a recombinant vaccine. The objectives of this study are to obtain VP19-encoding gene of WSSV from Situbondo, Indonesia. This research conducted through several stages, DNA genome isolation of Penaeus monodon infected with WSSV, amplification of VP19-encoding gene, isolation of VP19-encoding gene, ligation of VP19-encoding gene into pGEM-T Easy vector, transformation to Escherichia coli, recombinant vector screening, vector isolation using mini preparation technique, vector verification, and sequencing. The result of cloning shows that the size of VP19-encoding gene from Situbondo isolates is similar to VP19-encoding gene from the abroad one, which is 366 bp. However, the sequence result shows that there are some differences on bases and amino acid. However, the result of sequencing shows there are difference of five base and three amino acid arranged VP19 sequence the Situbondo isolate with isolate from several countries. The similiarity of the Situbondo isolate sequence with the other isolate (from Indonesian and other countries) was only 98%. This difference indicates the importance of making a vaccine from a local WSSV genes especially Situbondo isolate.Keywords: white spot syndrome virus, VP19, Penaeus monodonABSTRAKWhite spot syndrome virus (WSSV) merupakan patogen yang paling serius menyerang udang windu dan telah menghancurkan industri udang windu di berbagai negara, termasuk di Indonesia. Penggunaan vaksin WSSV yang didesain berdasarkan isolat WSSV luar negeri kurang efektif karena diduga WSSV yang menyerang udang Indonesia telah mengalami mutasi dan memiliki perbedaan sekuen. Untuk itu, penggunaan isolat WSSV asal Indonesia, khususnya Situbondo sebagai cetakan dalam memproduksi vaksin rekombinan untuk imunisasi udang di Indonesia sangat perlu dilakukan. Viral protein-19 (VP19) merupakan protein pembungkus WSSV yang penting karena keterlibatannya dalam infeksi sistemik pada udang, sehingga dapat dikembangkan sebagai vaksin rekombinan. Tujuan penelitian ini adalah untuk mendapatkan gen penyandi protein permukaan VP19 virus WSSV isolat Situbondo. Tahapan penelitian yang dilakukan pada penelitian ini adalah isolasi DNA genom udang windu yang terinfeksi WSSV, amplifikasi gen penyandi protein VP19, isolasi gen penyandi protein VP19, ligasi gen penyandi protein VP19 ke dalam plasmid pGEM-T Easy, transformasi plasmid, skrining plasmid rekombinan, isolasi plasmid dengan teknik mini preparation, verifikasi plasmid dan pengurutan. Hasil pengklonan menunjukkan bahwa ukuran gen penyandi protein VP19 isolat Situbondo sama dengan ukuran gen penyandi protein VP19 isolat asing yaitu 366 pb. Namun hasil pengurutan menunjukkan adanya perbedaan lima basa dan tiga asam amino penyusun sekuen VP19 isolat Situbondo dengan isolat dari beberapa negara lain. Kemiripan sekuen isolat Situbondo dengan isolat lain (dari Indonesia sendiri maupun dari negara-negara lain) hanya sebesar 98%. Adanya perbedaan ini mengindikasikan pentingnya pembuatan vaksin dari gen WSSV lokal khususnya isolat Situbondo.Kata kunci: white spot syndrome virus, VP19, Penaeus monodon

ABSTRACT This study aimed to analyze the genetic diversity of bacteria associated in bioflocs using 16S-rRNA polymerase chain reaction (PCR) with ARDRA technique. A total of 38 dominant bacterial isolates was obtained from bioflocs samples and of these isolates, 16S-rRNA gene was then isolated and amplified using PCR. The 16S-rRNA gene of the isolates was then cut using HaeIII (5’-GG↓CC) and HhaI (5’-GCG↓C) restriction enzymes resulting an ARDRA pattern which was further used as the binary data for the construction of phylogenetics tree that was used to estimate the group of bacteria. The result with HaeIII cut restriction enzyme from biofloc-associated bacteria gave 11 ARDRA patterns, while with the restriction enzyme HhaI gave eight ARDRA patterns. Phylogenetics of bacterial populations from biofloc-based cultivation system water consisted of at least 13 different bacterial species. Result of sequencing from two gene sample 16S-rRNA were identified as Microbacterium foliorumand and Pseudomonas putida. Keywords: bacterial diversity, ARDRA, biofloc, phylogeny ABSTRAK Penelitian ini bertujuan untuk menganalisis keragaman genetika bakteri bioflok menggunakan metode polymerase chain reaction (PCR) 16S-rRNA dengan teknik ARDRA.
