Analisis Optimasi Input Produksi Jagung di Desa Waimangurah, Kecamatan Wewewa Barat, Kabupaten Sumba Barat Daya

The purposes of the study were: to determine the influence of factors of production in corn farming on production and to analyze the level optimum use of production inputs in the corn farming. The research area was determined purposively. The analytical methods used to analyze the production inputs that affect the production were a Cobb-Douglass model of Production Function, and marginal product value analysis to determine the level of optimization of the use of production inputs. The results of the study are as follows: (1) Production inputs used in the corn farming are the area of land, seed, labor, Urea, NPK fertilizer, M-8 fertilizer, Super ACI fertilizer and fungicides. (2) The use of production inputs in the study area are as follows, Partially, only urea fertilizer significantly affected the corn production, while other production inputs were not significantly affected on the corn farming. (3) The use of production inputs in the study area have not been optimal. For the use of production inputs of urea, M-8 and Super ACI fertilizers was not optimal. Thus, the use of production inputs need to be added to reach optimal use of production inputs, while land, labor, seed, NPK fertilizer and fungicides have exceeded the optimal use so that the use of inputs should be reduced to gain optimal results.
