        abstract = {Laundry wastewater is a domestic liquid waste containing various organic and
inorganic pollutants that can contribute to the decline in water quality. If directly
discharged into water bodies, it can cause environmental problems. This study
aims to synthesize magnetite nanomaterial modified with peanut shell extract
(Fe{$_3$}O{$_4$}?AHL) derived from household waste and to apply it as an adsorption
medium in a wastewater filtration system combined with zeolite. The synthesis of
Fe{$_3$}O{$_4$}?AHL was carried out using the reverse co-precipitation method with water
as the solvent at a temperature of 60?C. Fe{$_3$}O{$_4$}?AHL was characterized using
FTIR, XRD, and SEM-EDX. Wastewater before and after filtration was tested for
COD, TSS, TDS, detergent, pH, and temperature parameters to determine the
performance and regeneration ability of Fe{$_3$}O{$_4$}?AHL as a filtration medium for
laundry wastewater. The FTIR and XRD spectra showed that the produced
magnetite was pure and not mixed with other iron oxides. SEM-EDX
characterization showed that Fe{$_3$}O{$_4$}?AHL had a rough surface with irregular size
and distribution, with the main elemental composition consisting of Fe, O, and C.
The crystallite size and particle size of Fe{$_3$}O{$_4$}?AHL were 4.83 nm and 250.97 nm,
respectively. The application of the combination of Fe{$_3$}O{$_4$}?AHL and zeolite as
filter media showed good performance in reducing COD, TSS, TDS, and
temperature parameters compared to filters without Fe{$_3$}O{$_4$}?AHL media.
Meanwhile, the combination of Fe{$_3$}O{$_4$}?AHL and zeolite as an adsorption medium
in the filter caused an increase in the pH parameter, but it was still within the
required quality standard range. The regeneration study results showed that the
filter with the combination of Fe{$_3$}O{$_4$}?AHL and zeolite still had good potential to
be reused in laundry wastewater treatment for up to five filtration cycles, where
the filter performance in reducing COD, TSS, and detergent remained relatively
stable up to the fifth cycle.}
