ASSESSMENT OF ENVIRONMENTAL IMPACT ON BIOFLOC TECHNOLOGY APPLICATION IN SHRIMP FARMING ACTIVITIES WITH LIFE CYCLE ASSESSMENT METHOD  

The application of biofloc technology on white shrimp farming activities needs to be evaluated, related to the use of natural resources and electrical energy that could potentially result in environmental impacts with high investment costs. The purpose of the research is to analyze environmental impact and determine management strategies of shrimp farming based biofloc technology. This study is a quantitative descriptive research using life cycle assessment method. The study is limited to farming activities in the pond "cradle to farm gate", the unit used is the production of 1 ton of white shrimp. The results demonstrate that bioflok technology is able to increase production per unit area of land used to harvest size. ± 16.4 g/ head with value of FCR 1.3, SR 86 - 92%, and 15,6% of SGR. Production per ton of white shrimp : acidification (Acd): 63.39 ± 15.37 kg SO2 eq, ; eutrophication (Eut): 14.10 ± 3.28 kg PO4 eq, ; global warming potential (GWP) : 7336.77 ± 1,460 kg CO2 eq and cumulative energy use (CEU): 101, 64 ± 18,84 GJ. Management strategies need to be done with improved feeding management based on water quality, reduction in electrical energy consumption, implementing partial harvest and added the sewage treatment ponds.
