Abstract

Decreasing of sediment quality was caused by ammonia due to the degradation of uneaten feed is a problem in tiger shrimp (Peneus monodon F.) culture. Biotechnology application may be can be used to solve this problem due to environmental safety. The objective of this research was to know the influence different substrat composition and effectivity of application of biotechnology product on ammonia reduction in culture sediment of tiger shrimp. Experimental laboratoris and split plot design based on completely randomized design was applied in the research. The main treatment was the substrat substrat composition (A= sand 25% and clay 75%; B— sand 50% and clay 50%; C = sand 75% and clay 25%); as sub-treatment was epicin concentration 1,0 ppm and as a group was day (0; 2; 4; and 6) with three replication. Anova result indicated that applipationtl of biotechnology product, especially substrat composition was not significantly affect on the ammonia sediment reduction in in the culture medium of tiger shrimp (P>0.05). Epicin dose of 1.0 ppm and day as sub-treatment has a significantly affect (p<0.05) in reducing ammonia at second day. The concentration rA 1.0 ppm of probiotic as biotechnological product • indicated the ability to reduce ammonia in the sediment of culture medium of tiger shrimp
