EFFECTIVENESS OF PHYTOREMEDIATION METHODS WITH VARIATION OF AMOUNT OF HEACH HONEY PLANTS (EICHHORNIA CRASSIPES) TO REDUCE COD EFFLUENT IPAL PARAMETERS IN KAWEDAN PUBLIC HEALTH CENTER, KABUPATEN MAGETAN

Abstract

Abstract. Biological treatment processes can use microorganisms and phytoremediation of aquatic
plants which are now widely used to reduce various levels of toxic metals or organic substances. This
aquatic plant is considered quite easy to obtain and effective in absorbing various toxic metals and
organic substances into plant tissues. To determine effectiveness of the phytoremediation method
with variations in the number of water hyacinth plants (Eichhornia crassipes) to reduce the COD
Effluent parameters of IPAL at the Kawedanan Health Center, Magetan Regency. This type of
research is a quassi experimental research study, namely research that refers to the treatment of
reducing COD levels in puskesmas waste water before and after being treated. This type of research
is an experiment or trial using the phytoremediation method, namely (Eichhornia crassipes). This
descriptive analysis is used to compare the reduction in COD parameters before treatment and after
treatment using the water hyacinth phytoremediation method and then compared which is
presented in the form of descriptive analysis and discussion. The object of this research is
community health center wastewater and COD examination samples with 3 replications without
treatment at 0 days and 7 days and treatment every 7 days. Based on pre-research that I conducted
within 7 days, the effectiveness of COD levels could decrease to a smaller level. The overall average
reduction in COD levels during treatment was 62 mg/l. The overall effectiveness of water hyacinth
utilization in reducing COD levels in the IPAL effluent at the puskesmas is 79%.
