Abstract

This research was conducted to know the technical and financial aspects of white shrimp (Litopenaeus vannamei) culture in coastal sandy soil area of Bantul Regency. The samples of farmers were determined by stratified sampling method based on the ponds width. The data were colected by observation and interviews methods. The samples in the study were 41 farmers as respondents perponds from the population of 290 ponds. Samples were consisted of three categories : 1,000 m²/pond for 16 farmers: 1,000-1,500 m² /ponds for 14 farmers and >1,500 – 2,500 m²/pond for 11 farmers. The results showed that the white shrimp culture in Bantul District coastal sandy soil area was an intensive system with average pond width 1,300 m². Average pond category < 1,000 m2 was 636 m²; average pond category 1,000-1,500 m² was 1,357 m² and average pond category >1,500 – 2,500 m² was 2.191 m². Generally the fixed costs incurred IDR 24,876,128 /pond/cycle and variable costs IDR 72,839,121 /pond/cycle (IDR 218,517,362/ pond/ year). The revenue of the culture was IDR 109,709,805 /pond/year, with the ratio value between the total revenue with total costs [Revenue (R) /Cost (C) ratio] was 1.37. The Break Event Point (BEP) of shrimp products was 4,909 kg and the Break Event Point (BEP) of shrimp price was IDR 34,312. The highest productivity of shrimp was 19.7 ton/ha/cycle, which be cultured in the 1,000-1,500 m² ponds, with incomed IDR 169,507,143 /pond/cycle and the Revenue/Cost ratio (R/C ratio) was 1.60.
