| dc.description.abstract | Utilization of plants to improve water quality coul
d be done by utilizing aquatic plants.
One of plants species that can be used was kiambang
(Salvinia molesta). The purpose
of this research was to improve water quality in po
st-coal mine ponds that were used
for fishery cultivation. The method oh this resear
ch was laboratory test. Utilization of
kiambang plants was determined to absorb dissolved
materials in the water to improve
water quality. Laboratory research were done side b
y side with plants trial in the pond
of post-coal mine water that used for fish farming.
The experiment was carried out for 7
(seven) days by observing the water quality changes
in the aquarium that used as
research medium. Parameter analyzed were dissolved
oxygen, pH, NO
2
, NH
3
and H
2
S.
The result of dissolved oxygen was 3.86 mg/L to 4.3
5 mg/L; pH 5.5 to 8.1; NO
2
, 0.89
mg/L to 0 mg/L; NH
3
, 1.99 mg/L to 0,1 mg/L and H
2
S, 2.3 mg/L to 0.03 mg/L. | en_US |
