KINERJA EKSTRAK BIJI DURIAN (Durio zibethinus) YANG DIPREPARASI DENGAN PELARUT NaCl SEBAGAI BIOKOAGULAN UNTUK PENYISIHAN KEKERUHAN PADA AIR GAMBUT

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.
