Sri Handayani, Sefti Heza Dwinanti and Purnomo Hadi. 2020. Utilization of Carambola Sari (Averrhoa bilimbi L.) in the Maintenance of Vaname Shrimp (Litopenaeus vannamei) to Suppress Population of Vibrio sp. Green Colony. Jurnal Sains Teknologi Akuakultur, 3(1) : 33-41. This research was conducted in July-August 2018 at PT. SyAqua Indonesia Serang, Banten. It used Completely Randomized Design (CRD) with three replicates and three treatments which were bilimbi juice in 20 ppm (T1), 30 ppm (T2) and without bilimbi or control (CT). The monitoring of Vibrio sp., defined as total Vibrio sp., totalÂ Â yellow colony, total green colony, the ratio of total green colony, survival rate of shrimp and water quality. The result showed that bilimbi juice was able to suppress the population of Vibrio sp. in the maintenance media and shrimp body. At the end of the maintenance period (d7-d9), total population of green colony in treatment were lower than control with the ratio of the green colony was 0%. In contrast, bilimbi juice with concentration 20 ppm and 30 ppm had no significant effect (P>0,1). The best survival rate was given by T2 about 16% and based on regression y = 0.3589x+5.0279 the optimal dose to protect shrimp from Vibrio sp. by using bilimbi juice is about 264,62 ppm.

The purpose of this research is to explore effectiveness from every part of Phyllanthus niruri such as leaves (L), fruits (F), stem (S) and combination (C) of those parts that able to inhibit Aeromonas salmonicida growth by using different methods of extraction both infundation and maceration. Experiments has been done at Budidaya Perairan Laboratory, Sriwijaya University. In vitro analysis used tetracycline 30 µg/ml as positive control, bacterial culture at 1014 CFU/ml and concentration of each part of stone breaker was 20%, 40%, 60%, 80% and 100%. The result revealed that stone breaker extract produced by infundation and maceration methods exhibited inhibitory activity against A.salmonicida. Moreover, only maceration method had bactericidal effect, in fact fruits (F) and combination (C) was the best part of P. niruri which had higher inhibition zone than control (antibiotics). It was 16,9 mm and 17,3 mm respectively. However, the extracts are recommended to cure aeromonad infection due to bacterial resistance of tetracycline already increase. Thus, some extraction methods are needed to be developed for further research with minimum inhibition zone is 20 mm.Penelitian ini bertujuan untuk mengetahui efektivitas setiap bagian Phyllanthus niruri seperti daun (L), buah (F), batang (S) dan kombinasi (C) yang mampu menghambat pertumbuhan Aeromonas salmonicida menggunakan metode yang berbeda, ekstraksi infundasi maupun maserasi. Percobaan telah dilakukan di Laboratorium Budidaya Perairan Universitas Sriwijaya. Analisis in vitro menggunakan tetra siklin 30 g/ml sebagai kontrol positif, kultur bakteri pada 1014 CFU/ml dan konsentrasi masing-masing ekstrak adalah 20%, 40%, 60%, 80% dan 100%. Hasil penelitian menunjukkan bahwa ekstrak yang dihasilkan dengan metode infundasi dan maserasi menunjukkan aktivitas penghambatan terhadap A.salmonicida. Selain itu, hanya metode maserasi yang memiliki efek bakterisidal, ternyata buah (F) dan kombinasi (C) merupakan bagian terbaik dari P. niruri yang memiliki zona hambat lebih tinggi daripada kontrol (antibiotik). Masing-masing 16,9 mm dan 17,3 mm. Namun, ekstrak tersebut direkomendasikan untuk menyembuhkan infeksi aeromonad karena resistensi bakteri terhadap tetra siklin sudah meningkat. Oleh karena itu, perlu dikembangkan beberapa metode ekstraksi untuk penelitian selanjutnya dengan zona hambat minimal 20 mm.

ABSTRACT The aim of this research was to analyse the toxicity and immunogenicity of ECP of non-hemolytic S. agalactiae and to evaluate ECP as a material vaccine for prevention of S. agalactiae. Toxicity to tilapia was detected in the ECP. There was a chronicÂ mortality pattern which was shown after post ECP injection. By intraperitoneal injection into young tilapia (Â± 20 g), the median lethal dose were calculated at 633,9 Âµg/kg bodyweight for isolate 3 and 685,4 Âµg/kg bodyweight for isolate 5. Cytopathic effects of ECP to tilapiaâ€™s lymphocytes were observed during 0, 30, 60 and 180 minutes. A mixture of ECP caused nuclear granulation and cytoplasmic streaming after 60 minutes. Using immunodiffusion analysis, precipitate line was demonstrated against tilapia anti-ECP sera, and there was bio-specific type anti sera against for each isolate. The ECP vaccine effective to protect tilapia from S. agalactiae was injected intraperitoneally (IP) at 2 x 105 CFU/ml. Tilapia vaccinated with ECP from isolat 3 which proteinÂ 283 Âµg/kg bodyweight had a RPS value 60%.Â Tilapia vaccinated with ECP from isolat 5 which protein 408 Âµg/kgÂ had a RPS value 68%.

Sungsang IV Village is a village where most of the residents work as fishermen. The waters around this village have great fishery potential. The results of fish catches by fishermen are felt to be less than optimal due to a lack of knowledge about the latest technology in fishing. Fish Finder is one alternative that can be given to solve this problem because this tool can function to detect the presence of fish. Most of the residents of Sungsang IV Village don't know about the Fish Finder tool. This service activity aims to provide introduction and training regarding the use of Fish Finder to detect the presence of fish. The enthusiasm of the community is very visible from the number of training participants that exceeds the targeted number. This training is carried out by presenting material and direct practice of using the tool to make it easier for participants to understand the operating steps. The results of the evaluation of the questionnaire conducted showed that all participants felt very helpful with the training in the use of this Fish Finder tool.
