SUMMARY
Utilization of grain as a natural coagulant (biocoagulant) can reduce the use of
synthetic coagulants in peat water treatment. Grains have an active component in the
form of protein which can act as a coagulant agent. Durian seeds can be used as a
biocoagulant because it contains protein. This study aims to prepare, characterize and
determine the effectiveness of durian seeds in removing the color, odor, turbidity, TSS
and TDS of peat water. Durian seeds were prepared with variations of 1 M NaCl and
demineralized aqua. Coagulation was carried out using jartest at various doses of
biocoagulant (1, 2 and 3) g and original peat water and variations in pH (3, 4 ,5, 6 and
8). Characterization of biocoagulants was carried out by identifying functional groups
using FTIR, water content by gravimetric method, protein content by the Lowry and
Kjeldahl method, and starch content by the Luff Schoorl method. Determination of the
effectiveness of durian seed biocoagulant is by determining the dose of biocoagulant
(1, 2 and 3) g and original peat water. In addition, the effectiveness of the biocoagulant
performance was determined from the analysis of peat water after coagulation and
compared with the combined coagulant performance (alum+biocoagulant) by
calculating the settling time and the resulting sludge volume. The coagulation pH was
obtained from pHzpc which was 7.5 so that the pH used was four below pHzpc and
one above pHzpc. The results of FTIR analysis showed the presence of functional
groups from the O-H (carboxylic acid), N-H (amine), C-H (alkane), C=O (carbonyl)
and C-O (carboxylic acid) groups. Biocoagulant BDNaCl obtained a water content of
10.84% and BDH2O of 9.35%. The protein levels produced by the biocoagulants BDNaCl
and BDH2O were 0.65% and 0.50% by Lowry method and 11.25% and 11.59% by
Kjeldahl respectively. BDNaCl biocoagulant produced starch content of 83.34% and
BDH2O of 83.56%. The most effective biocoagulant performance in treating peat water
using a biocoagulant prepared with 1 M NaCl (BDNaCl-2) at pH 3 at a dose of 2 g with a
removal percentage of 55.56% TSS, 54.76% TDS and color 27.65%. Biocoagulant
prepared with H2O solvent (BDH2O-1) at pH 8 dose of 1 g was able to remove 22.23%
TSS and 76.19% TDS. This result complies with the PERMENKES RI No. 32 of 2017
and PP no. 22 of 2021, but has not been able to remove the turbidity of peat water.
However, the combined coagulant (alum + biocoagulant) is able to remove all
parameters, the color, TSS and TDS turbidity as well as settling time and sludge
volume, faster and less than alum.
