Dampak Lindi TPA Jatibarang terhadap Keanekaragaman dan Kelimpahan Plankton di Perairan Sungai Kreo Kota Semarang
Abstract: Plankton
is the important
organisms in aquatic
ecosystems. Kreo river
subjacent landfill leachate
tank Jatibarang interchangeable physicochemical changes by leachate contaminants which enter the river due to leakage
of leachate tank. The will impact on the diversity and abundance of plankton.
The aims of this study is
apperceiving Jatibarang leachate
influence the diversity
and abundance of
plankton in Kreo
River. The study was conducted
from April to May 2015. Plankton samples taken by purposive sampling using a
plankton net which 25 number with a mesh size of 40 µm. Sampling was conducted
plankton with four stations of three sampling each points of stations and
physicochemical measurements that include temperature, brightness, pH, COD, and
BOD. That are contaminated leachate of II stations with an index of H’ value
1.40 and abudance 75 ind/l and
the stations III
with index H’
value 1,53 and
abudance 95 ind/l.
The location padding contaiminatef leachate that the
stations I had an index value H’ 195 and abudance values 191 ind/l and stations
which has undergone restoration gas an index value H’ 2,07 and abudance 207
ind/l. From the results shows that Jatibarang landfill leachate that entered
the Kreo River affect the physicochemichal conditions of water allows for
lowering the diversity and abudance of plankton
