The result of the business feasibility analysis obtained was the profit value of Gracilaria sp., cultivation in Domas Village, which was 115,168,232 / year, R / C of 1.32% means that the business was worth running, the payback period value was 1.51 years since the company was established. The product's BEP (kg) value in this study was 1,320 kg. Meaning that the break-even point will be reached if the cultivation produces Gracilaria sp. So that the business can be developed. As for the sensitivity, the value increases acceptable operating costs by 5%. In addition, the calculation of sensitivity to the decline in selling value is known to be a very sensitive variable because it’s 3% decrease will lower the of R / C value to less than 1.
