The efficiency of duck rice integrated system for sustainable farming

Abstract

Duck rice integrated system is one of the innovations that can be applied by farmers to increase the efficiency and sustainability of land use in rice field. Research on the effect of ducks in cultivation and rice fields has been carried out but has not examined the effect of production factors and the efficiency of using these production factors in ducks rice integrated system. This study aimed to analyze the production function and efficiency of production factors in implementation of duck rice integrated system (STIP). All farmers who implemented an integrated system in Subak Lanyah, Bongan Village, Tabanan District were selected as respondent (100%) and compare with 13 farmers who not implemented it choosen by stratified random sampling. Data analysis used the cobb-douglass production function to determine the influencing factors and the efficiency of the production factors. The results showed that 1) Implementation of duck rice integrated system on paddy field in Subak Lanyah, Tabanan gave a significant effect on rice production together with an organic fertilizer use (urea and ponska). Farmers who apply duck rice integrated system tend to use fewer input factor. 2) The use of input factors such as paddy field, an organic fertilizer (urea and ponska), pesticides in farming are not efficient yet, while labor is not efficient. The total value of the regression coefficient of all production factors is equal to 1.029 indicated that the ducks rice were at increasing returns to scale. Therefore, integrated rice farming with ducks is feasible to develop.
