An input-output model of integrated farming system

Abstract

Tlie increase in the human population caused a decrease in the world agricultural area. Meanwhile, the agriculture sector is the biggest contributor to world food production. The integrated fanning system is integrating plants, livestock and fisheries management in a single harvesting cycle. The integrated farming system is one of the solutions to increase the efficiency of food production Plants are able to become food sources for livestock and fish. In this case, the output from plants turned into input for livestock. Meanwhile, fish and livestock excrement that used as plant fertilizer mean that livestock’s output becomes the input for the plants. The major purpose of the integrated farming system is to yield optimization. Optimization stands for minimizing of feeding and fertilizer cost and to optimize the yield of crops and livestock production. The simulation-based on the secondary data of integrated organic’ vegetables and livestock farming that has been done in Gapoktan Pandan Wangi in Village of Karehkel, District of Bogor. Leontief input-output economic model used to calculate the output of a component to meet the input of corresponding components. For the increase of vegetable sector demand of Rp500.000,00 required the increase of vegetable sector production of Rp46.915,097. For the increase of livestock demand od Rp200.000.00 required the increase of production in amount of Rp867.4S8,41. Thereby for Bokashi sector, in the increase of demand of Rp400.000,00 required the increase of production of Rp975.322,00. For the increase of silase sector demand of Rp30.000,00 required the increase of production of Rp76.456,00.
