Abstract
As the byproduct of it’s activities,
Dr Sardjito General Hospital produces waste-water which may contain hazardous
microorganisms and substances. Two of the chemicals in the hospital’s waste
water which had been exceeding the threshold were phosphate and ammonia. Excessive
phosphate may lead to septicemia, while ammonia makes irritation and disturbs
chlor disinfection. One of the treat-ments which can be used is
phytoremediation by using Eichornia crassipes. The aim of the research was to identify the
effect of this water plant in repair-ing the quality of the waste water by
conducting an experiment with pre test post test with control group design. The
plants were placed at sedi-mentation II chamber and were acclimatized
beforehand. The results show that the mean decrease of
phosphate in the control group was 0,554
mg/l,
while in the treat-ment group was 0,916
mg/l. For ammonia, the mean decrease in the control group was 2,732 mg/l, and in the treatment group it was 5,829
mg/l. The data were then analyzed by using
Mann Whitney test at 0,05 signification level, and yielded p-values of 0,020
and 0,026 for phosphate and ammonia reduction respectively, which means that
the phytoremediation was signifi-cantly effective
for reducing the two chemicals. The phosphate were reduced 22,973% and the
ammonia were of 28,33%.
