| dc.description.abstract | Numbers of parameter are referenced to determine the characteristics of wastewater. Biodegradability and
toxicity are determined based on the biological oxygen demand (BOD) to chemical oxygen demand (COD)
ratio. Contaminant monitoring in wastewater is an important consideration in choosing among alternative
waste management systems. Information relating to wastewater parameters can be used to improve the
efficiency and effectiveness of wastewater treatment plants (WWTP). This research focused on identifying
parameter conditions and classifying the biochemical oxygen demand (BOD) to chemical oxygen demand
(COD) ratio of laboratory wastewater at the University of XYZ, Indonesia. Sampling of laboratory wastewater
from two faculties or Department in the University of XYZ the Faculty of Agricultural Technology and the
Faculty of Pharmacy, was carried out using a grab sampling method. The wastewater quality parameters
of temperature, pH, turbidity, total suspended solids (TSS), COD, BOD, and heavy metals were observed
and the results obtained were compared with quality standards contained in Regulation of Environment
and Forestry Ministry No. 5, 2014. Wastewater characterisation was then identified based on the results of
BOD/COD calculations. The results showed that the quality parameters of pH, BOD, COD, TSS and total
dissolved solids (TDS) in laboratory wastewater exceeded the quality standards set. The BOD/COD ratio
of wastewater taken from the laboratory of the Faculty of Agricultural Technology was 0.3 and for the
Pharmacy Faculty was 0.4, indicating that both were biodegradable. The wastewater treatment
recommendation was a combination of physical (biofilter) and biological (phytoremediation) methods.
The results of this investigation were used as considerations for the construction of a wastewater treatment
plant (WWTP) at the University of XYZ which would meet both aesthetic and environmental requirements. | en_US |
