Abstract:
This research has the objective to study the feasibility of rice and shrimp dual farming by studying its costs and return. Interviews were used as a tool for data collection. Data analyses to assess the feasibility of the project include cash flows, Net Present Value (NPV), Benefit-toCost Ratio (BCR), Internal Rate of Return (IRR), Payback Period (PB), and sensitivity analysis. This study finds that the rice farmings NPV is 134,770.09 Baht and the white shrimp farmings NPV is 1,422,227.25 Baht, both of them are positive and greater than 1. The IRR of rice farming is 42%, and the IRR of white shrimp farming is 42%, both are greater than the set IRR of 8.73%. The BCR of rice farming is 1.62, and the BCR of white shrimp farming is 1.34, both are greater than 1. According to these investment evaluation criteria, this project is worth investing. The sensitivity analysis shows that if the discount rate changes to 9%, 10%, 11%, 12%, 13%, 14%, and 15%, rice farming still is worth investing, while white shrimp farming is not because its IRR is negative, and BCR is very close to 1. If rice price is under 7.50 Baht, this project is not feasible because the IRR is lower than 8.73% and declines further, the BCR is very close to 1. And if the labor costs 350 and 400 Baht, while revenues and investment costs stay the same, both rice farming and white shrimp farming are still worth investing because the IRRs are greater than 8.73% and the Payback Periods are short. This study recommends that the rice and white shrimp dual farming is worth investing because the NPV is positive and greater than 0, IRR is greater than the projects discount rate. However, interested investors can invest in this kind of project under normal circumstances but they should compare the return of this project with those of other projects as well.
