HASIL CEK TURNITIN: PENGARUH AERASI TERHADAP PENGOLAHAN LIMBAH CAIR RUMAH SAKIT DENGAN METODE CONSTRUCTED WETLAND

The aquatic plant Typha latifolia, water bamboo (Equisetum hyemale), in constructed wetland
(CWs) system as a bioremediation unit is expected to be able to solve problems related to
wastewater treatment in health care facilities. This study aims to determine the effect of aeration
and types of aquatic plants T. latifolia and E. hyemale on the reduction of hospital wastewater
parameters Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Ammonia, and
Total Suspended Solid (TSS) using the CWs method. This study used a quasi-experimental design,
namely the provision of aeration and without aeration combined with CWs and aquatic plants T.
latifolia and E. hyemale to treat hospital wastewater parameters (BOD, COD, Ammonia, and TSS)
to compare with specified quality standards. The treatment in this study was the provision of
aeration in the wetland tub planted with T. latifolia and E. hyemale. This study found the highest
removal percentage for all parameters in WCs with E. hyemale without aeration, namely BOD =
72.58%, COD = 82%, TSS 78.77% and ammonia 75.31%. While the lowest removal was in CWs
with T. latifolia with aeration, namely BOD = 38.81%, COD = 55.14%, TSS = 42.36% and
ammonia 36.38%. The most significant decrease in levels was in the COD parameter. This
research is not perfect, so it needs to be continued by adding retention time variations and the
number of plants.
