Djusman, H.
In the limited resources of land for agriculture nowadays, swamp land as one of alternative can be developed to overcome problem of food security. Swamp land in Indonesia spread in Sumatra, Kalimantan and West Papua where in Sumatra; the largest swamp land area is located in South Sumatra Province. Unfortunately, only few of the area has been utilized due to its fragile land types where farmers only cultivate rice once a year and let the land lie fallow afterward. The purpose of this paper is to develop a feasible farming system model and give an overview of financial aspect of swamp land optimization projects to help farmers and practitioner utilize and optimize swamp land more. Swamp land can be optimized based on its water level. Shallow and mid swamp land can be cultivated using rotation model of crops (rice, corn, cassava), horticulture (cucumber, long beans, watermelon etc), fish farming (catfish, snake head fish, tilapia), and duck farming; whereas submergence tolerant rice varieties can be cultivated alternating with fish farming in deep swamp land. This feasibility study shows that using actual input and low projected output, swamp land can show financially feasible with the NPV is USD 324,568.28, BCR value is 1.11, and IRR value is 302%. Sensitivity analysis shows that this project is sensitive in the increasing 17.5% of maintenance and other operating cost. Project also shows its sensitivity when sales are decreasing as much as 13%. Thus, implementation of this farming model is expected to increase farmers' income and increase household food supply as well as village food supply
