MANAJEMEN KUALITAS AIR DENGAN TEKNOLOGI BIOFLOK: STUDI KASUS PEMELIHARAN IKAN LELE (CLARIAS SP.)
ABSTRACT: Biofloc technology
is one of the alternative to overcome the problem of water quality of
cultivation environment which was adapted from conventional waste management
techniques. The purpose of this study was to assess the young catfish culture
by applying bioflocs of some consortium products, such as Bacillus megaterium
(BM), Supernit (SP), Depok 165 (DP165), Kayajaga (KJ) compared to non biofloc
application for improving the water quality. The results of this study and
statistical test showed that the lowest concentration of TAN by probiotic KJ
was about 2.56 mg L-1, while the control was about 5.47 mg L-1, and the
consortium of bacteria gave effect to
TAN value (p<0.05). The Lowest concentration of amonia by probiotic
KJ was about 0.0001853 mg L-1, while control was about 0.0003973 mg L-1, and
the consortium of bacteria did not give effect to amonia value (p>0.05). The
lowest concentration of nitrite by probiotic BM was about 0.065 mg L-1, while
the control was about 0.124 mg L-1, and
the consortium of bacteria gave effect to the nitrite value (p<0.05). The
lowest concentration of nitrate by probiotic BM was about 1.203 mg L-1, while
the control was about 3.437 mg L-1, and the consortium of bacteria gave effect
to the nitrate value (p<0.05). Consortium of bacteria gave effect to the COD
value (p<0.05), but all bioflocs treatments had an average value of COD
higher than the control. The conclusion that the bioflocs aplication was able
to improve the water quality shown by decreasing parameter values of TAN
concentrations, ammonia, nitrite, and nitrate.
