Aquaculture is a growing sector with an annual growth rate Aquaculture has a world annual growth rate of 5.8% over the period 2000-2016. Aquaculture in Indonesia reached 17.22 million tons in 2017, where shrimp is a major export commodity. For the process of further industrialization, shrimp as a superior aquaculture commodity, still experiences several obstacles, one of which is a disease caused by the bacterium Vibrio sp. (Vibriosis Syndrome). Therefore, management is needed through the use of functional feed with synbiotic supplementation. This study aims to determine: (1) the formulation and effect of feed supplementation using synbiotics: prebiotics (Kappaphycus alvarezii and Spirullina sp.) and probiotics (Bacillus cereus and Halomonas alkaliphila), to the survival, growth and resistance of vibriosis in white shrimp (Litopenaeus vannamei), (2) determine the biological and economic feasibility in the application of pilot scale synbiotic supplements, (3) and determine the business feasibility of synbiotic supplement products in terms of market, financial, and technical aspects. The results of feed performance testing showed the highest survival rate of shrimp was 92.62±0.02% in the B. cereus and H. alkaliphila 1:1 probiotic variation groups, which were significantly different from controls namely 60.04±0.03% (p <0,05). Pilot scale testing showed the best biological performance achieved by a synbiotic treatment pool with estimated survival and feed convertion ratio were 72.28% and 1.38, respectively. Based on the results of the development of the production scheme to produce 1000kg of white shrimp, it can be seen that the synbiotic pool has an investment cost of Rp64,730,500, an operational cost of Rp46,471,064, a sale of Rp180,000,000, and a profit of Rp36,525,427, while the control pool has an investment cost of Rp75,230,500, operational costs of Rp.47,273,383, sales of Rp180,000,000, and profit of Rp34,361,865, both of which are considered financially feasible. In the worst case scenario due to Vibriosis, with the same investment and production value, the synbiotic pool will generate sales of Rp172,800,000, profit of Rp30,045,427, is considered financially feasible while for control kolan will result in sales of Rp142,200,000, profit of Rp341,865, and is valued not financially feasible. The results of the business feasibility analysis from the SWOT analysis show the three greatest values are in the factor of benefit, market potential, and the environment with values of 0.306, 0.216, and 0.098 respectively. In addition, the financial feasibility analysis of synbiotic supplements shows the value of the payback period at 2 years 2 months, NPV of Rp369,560,212 IRR 38.41%, and B / C ratio of 1.72, so that the business plan for synbiotic supplement production is categorized as feasible. From this study, it can be concluded that the best variation of synbiotic supplements is the prebiotic ratio of K. alvarezii: Spirullina 3:1 and the ratio of probiotics (total 108CFU / ml) B. cereus: H. alkaliphila 1:1 can increase the survival and resistance of white shrimp disease. Synbiotic supplements are suggested to be biologically and economically feasible in ideal and vibrio scenarios to be applied and developed as supplement products in the production of white shrimp, and the business of producing large scale synbiotic supplements is considered to be market, financial, and technical feasible to be developed.
