Abstract:
Utilization of grain as a natural coagulant (biocoagulant) can reduce the use of
synthetic coagulants in peat water treatment. Durian seeds can be used as a
biocoagulant because they contain protein. This study aims to prepare, characterize
and determine the effectiveness of durian seeds in treating peat water with 1 M
NaCl. Characterization of biocoagulants was carried out by determining protein
content using the Kjeldahl test. Determination of the effectiveness of durian seed
biocoagulant performance was determined at the coagulation pH (3, 4, 5, 6 and 8).
The protein content determined by the Kjeldahl method on BDNaCl biocoagulants
was 12.25%. The results of turbidity analysis using biocoagulants BDNaCl with
various pH variations have not been able to remove turbidity in peat water.
Therefore, the aim of this research has not been achieved.
