MENGGUNAKAN ISOLAT BAKTERI LIPOLITIK
%X Shrimp aquaculture waste contains high amounts of organic matter which can
cause pollution to the aquatic environment. Waste from shrimp farming consists of
feed residues, shrimp feces, and colonies of pathogenic bacteria, so that it can
interfere with the survival of the shrimp itself and the water body it will pass
through. Overcoming environmental pollution requires environmentally friendly
waste treatment, one of which is bioremediation. Bioremediation can be done using
bacteria to break down pollutants in waste.
This study aims to obtain lipolytic bacteria from tannery waste and its
potential as a bioremediation agent for shrimp pond waste. The isolation results
obtained 2 isolates from solid waste with codes PK1.1.2 and PK1.2.2 and 2 isolates
from liquid waste with codes SK3.2 and SK3.4. Degradation of pollutants in shrimp
pond waste was measured by parameters Biological Oxygen Demand (BOD) and
Chemical Oxygen Demand (COD) which were measured on day 0 and day 7, and
Total Suspended Solid (TSS) parameter which was measured on day 0 and day 5.
The biggest decrease in BOD occurred in shrimp pond waste that had been
added by isolate SK3.4, from the initial level before bioremediation was carried out
at 130.9 mg/L to 109.4 mg/L. The largest decrease in COD also occurred in shrimp
pond waste that had been added by isolate SK3.4, from the initial level before
bioremediation was 253.2 mg/L to 202.3 mg/L. While the largest decrease in TSS
occurred in shrimp pond waste that had been added by isolate PK1.1.2, from the
initial level before bioremediation was 25.333 mg/L to 21.1 mg/L.
