SUMMARY
Durian seeds (Durio zibethinus) have an active component in the form of protein
and starch which can act as coagulant agent. This study aims to prepare,
characterize and determine the best method for preparing durian seed
biocoagulant using dry mil (DM) and wet mill (WM) method in removing color,
odor, turbidity, TSS and TDS of peat water. Characterization of biocoagulant
included functional groups identified using FTIR, water content by gravimetry,
protein content by the Lowry method and Kjeldahl method, and starch content
analyzed by the Luff Schoorl method. Coagulation was observed using the jar floc
test at various doses (1, 2 and 3) g and coagulation pH (3.0; 4.0; 5.0; 6.0; and 8.0).
Determination of the effectiveness of durian seed biocoagulant performance is
determined from the analysis of peat water after coagulation, sedimentation time
and the amount of sludge produced. The results of FTIR analysis of DM and WM
biocoagulant indicated the presence of O-H (carboxylate), C-N (amine), C-H
(aromatic), C-O (ether), and C-C (alkane) functional groups. DM biocoagulant
contains a water content of 8.88% and WM 9.63%. The protein levels produced
by DM and WM biocoagulant were 1.05% and 0.12% by Lowry method and
10.24% and 9.34% by Kjeldahl respectively. DM biocoagulant produced starch
content of 83.85% and WM 83.00%. WM biocoagulant is more effective in
treating peat water than DM biocoagulant. WM biocoagulant was able to remove
TSS of 55.56% and TDS of 86.39%, which was coagulated at pH 5, dose of 2 g,
with a sedimentation time of 4 hours and obtained a sludge volume of 5.5 mL.
Even though the quality of peat water does not meet all the test parameters in
PERMENKES RI No. 32 of 2017 and PP No. 22 of 2021, but several parameters,
namely pH, TSS and TDS of peat water coagulated using WM biocoagulants have
complied with these regulations. The use of DM1 and WM2 biocoagulant added
with a 1:1 commercial coagulant (Tawas) is more effective in improving the
quality of peat water in terms of turbidity, TSS and TDS. Therefore, the results of
this study indicate that DM and WM biocoagulant are more effective as auxiliary
biocoagulant, because they can improve the quality of peat water.
