Abstract

To be able to respond to the dynamics of stakeholder demand preferences, the tilapia business enlarger should always innovate. This research has special purpose, that is (1) Analyzing cost and return of experiment of intensification of tilapia enlargement of floating net cage system with and without probiotics, (2) To analyze growth rate and survival rate cultivation of tilapia floating net cage system with and without probiotics.
This research is a collaborative research survey and experiment. The survey was conducted on 50 indigenous tilapia business actors, as a source of data for analysis of return cost ratio. Experimental research was conducted to determine the effect of probiotic dose on feed to the growth rate and survival of tilapia. Sampling using quota random sampling method, with the number of respondents 50 people. The effect of probiotic dose on feed on the growth rate and survival of tilapia was analyzed using variance analysis. Cost and return of experiment intensification of tilapia enlargement of floating net cage system with and without probiotics was analyzed by return cost ratio (RCR) analysis.
The results showed that the maintenance of tilapia fish floating net cage system with the provision of probiotics has a RCR coefficient greater than without the provision of probiotics. Provision of probiotics significantly affect the rate of growth and survival of tilapia.
