Abstract :
The purpose of this research is to identify the process of shrimp farming of natural system, to analyze production cost and income of shrimp farming business and to analyze what factors influence shrimp pond production of natural system. Methods of data analysis used descriptive method and method of Multiple Linear Regression. The results obtained: The process of shrimp pond farming system consists of natural land processing, pesticide administration, fertilization, maintenance, feeding and harvesting. Natural shrimp farmers earned an average of Rp 4,438,420 per hectare with average production cost of Rp 7,721,579 per hectare and partially (t-count); area of land and feed have real effect to shrimp farmers production of natural system. While education, experience and solid stocking did not significantly affect the production of shrimp farming system of natural system. Simultaneously (F-count) of all independent variables significantly affect the production of shrimp farming system, R2 of 0.662, it shows that 66.2% of the dependent variable (production) can be explained by independent variables (education, experience, , solid stocking, feed). While the remaining 33.8% influenced by other independent variables that have not been entered into the model.
