KUALITAS LIMBAH CAIR EKSTRAKSI SAGU (METROXYLON SP.) MENGGUNAKAN ALAT PENYARING SISTEM BERLAPIS PADA BEBERAPA WAKTU PENYIMPANAN
ABSTRACT: In order to produce
sago starch, sago bar had to be crushed and extracted using water to separate
starch from other compounds. In the sago processing, a lot of water was used to
extract sago starch and finally was discarded as liquid waste. In this study,
the quality of sago liquid waste, before and after applying a layer-based
filter containing: coir, charcoal, gravel and sand, was measured. The study was
designed with a different time of storage of the Sago liquid waste, namely
0,1,2,3,4, and 5 day of storage. Each day the liquid waste was filterd using
layer-based filter, and then the quality of the liquid waste was compared. The
parameters measured were total suspended solids, total dissolved solids, final
pH, and physical parameters such as smell and color. The results ofthis
studyshowed that quality decrese of sago liquid waste accurs during 5 days of
storage as indicated by increasing the total suspended solids (up to 1400 mg/L)
and the dissolved solids (up to 2000 mg/L), decresing the pH value (down to 5)
and arising unpleasant smells. Furthermore,the use of thelayer-basedfilterwas
effective enoughto restorethe quality of the sago liquid water bydecreasing
thetotalsolids, neutralizing thepH valueand reducingthe unpleasant smell
