Abstrak: The purpose of this research was to determined the effectivity of Phyllanthus niruri-Allium sativum powder in fish feed for controlling Vibrio alginolyticus infection on tiger grouper Epinephelus fuscoguttatus. In vitro test was conducted to evaluated Phyllanthus niruri-Allium sativum dosage combination (15+20, 15+25, 20+20, 20+25 and 25+20 g/L) to inhibit bacterial fish pathogen. The dosage combination of 20+25 g/L was given the highest inhibitory zone (12,33 mm in diameter) and this dosage was used for in vivo test. In vivo test consisted of four treatments; negative control, positive control, preventive dan curative. Tiger grouper (length 7,74±0,27 cm and weight 12,50±0,394 g) were reared in aquarium (60x30x30 cm3) with stocking density of 6 fishes/aquarium. The preventive teratment was fed with feed treatment (20+25 g/kg of feed) for 14 days, while the others treatment was fed with commercial feed. The 0,1 ml of V. alginolyticus at concentration of 104 cfu/ml were injected to fishes of positive control, preventive and curative treatment while negative control fishes were injected with PBS. Curative treatment fishes were given treatment feed (40+50 g/kg of feed) and negative control, positive control and preventive treatment fishes were given with commercial feed. The fish feed response, growth rate, survival rate, hematology, anatomy and water quality were observed for 7 days after injected. The result of research showed that suplemented of Phyllanthus niruri-Allium sativum in fish feed at preventive and curative treatment showed better survival rate, 83,33 % and 61,11 % respectively, than positive control 38,89 % (P<0,05).

Judul: Efektivitas campuran tepung meniran Phyllanthus niruri dan bawang putih Allium sativum dalam pakan untuk pencegahan infeksi bakteri Aeromonas hydrophila pada ikan lele dumbo Clarias sp.
Abstrak: Motile Aeromonad Septicaemia (MAS) caused by Aeromonas hydrophila induced serious epidemics of ulcerative disease in walking catfish (Clarias sp.). Purpose of this research was to determine the effective dosage of Allium sativum and Pyllanthus niruri powders mixed in commercial feed with more applicable method in the field. The treatments tested were four different dosages of A. sativum and P. niruri powders, namely A (0,1%), B (1,1%), C (2,1%), D (3,1%) and control, namely K⁻ (without A. sativum and P. niruri powders, and injected with PBS 0,1 ml) and K⁺ (without A. sativum and P. niruri powders, and infected with A. hydrophila 0,1 ml). The treatments was given for two weeks before challenging test, at 15th day test in vivo carried out by injecting A. hydrophila (108 CFU/ml) into the fish by intramuscular and observed for 10 days. Parameters measured were survival rate, absolute growth, specific growth rate, clinical symptoms, wound healing, organs morphology, and water quality. Data were processed statistically using completely randomized design ANOVA single factor. The results showed that the survival of treatment K⁻ was 100±0,00%, C 60±20%, A 40±40%, B 40±40%, K⁺ 33,33±11,55%, and D 20±0,0% (p<0,05). The survival was not significantly different between treatment K⁻ and C. Thus C (2,1%) was effective and could be for preventing MAS in catfish (Clarias sp.).
