EFEKTIVITAS PENURUNAN BAHAN ORGANIK PADA LIMBAH CAIR PENYAMAKAN KULIT MENGGUNAKAN TUMBUHAN KAYU APU (Pistia statiotes Pistia statiotes L.) SEBAGAI BIOFILTER
ABSTRACT: This objective of
the research was to know the ability of waterlettuce to decrease organic and
inorganic materials in liquid waste of leather tanning, to know detention time
needed by waterlettuce in decreasing organic and inorganic material, and to
know the effectiveness of waterlettuce as biofilter compared to Eichhornia
crassipes. The research used completely
randomized design with ten treatments (based on 10 days planed-detention time),
with three replication. Purified liquid
waste was analyzed including pH value, BOD, DO, TSS and chromium content. The data was analyzed using Test F on 5%
significant level and Turkey Test.
Effectiveness analysis was used to know the range of waterlettuce
effectiveness compared to Eichhornia crassipes. The results showed that waterlettuce
(Pistia statiotes L.) as biofilter in liquid waste of leather tanning decreased
pH value 39.25 %, BOD 67.05%; DO 72.24%, TSS 60.31%, and chromium content
74.51%. Detention time of waterlettuce
in decreasing organic and inorganic material in liquid waste of leather tanning
was ten days. Effectiveness of
Waterlettuce as biofilter in liquid waste of leather tanning to decrease
organic and inorganic is 99.33% of pH; 100.65% of BOD; 119.70% of DO; 10.16% of
TSS and 103.05% of chromium content.
Keywords: effectiveness,
