Abstract
Tanah di sekitar area tambang batu bara kabupaten Tapin,
Kalimantan Selatan mengandung polutan Polycyclic Aromatic
Hydrocarbon (PAH) dengan konsentrasi tinggi. PAH merupakan
jenis polutan organik karena sifatnya yang resisten di alam,
bersifat karsinogenik, dan meningkatkan risiko mutasi gen.
Tujuan penelitian ini yaitu (1) menentukan pengaruh variasi umur
kompos terhadap degradasi PAH pada proses co-composting, (2)
menentukan pengaruh penambahan surfaktan terhadap
degradasi PAH pada proses co-composting, dan (3) menentukan
efisiensi penyisihan PAH dengan metode co-composting.
Penelitian dilakukan dalam skala laboratorium selama 60
hari pengamatan. Variasi yang dilakukan berupa penambahan
surfaktan biodegradable (Tween 80) dengan konsentrasi 0, 2,
dan 4 % b/b. Variasi lainnya adalah umur kompos yang
ditambahkan, yaitu sampah segar, kompos setengah jadi, dan
kompos jadi. Campuran bahan kompos dengan rasio tanah
terkontaminasi dengan kompos adalah 50:50 % b/b.
Hasil penelitian menunjukkan bahwa penambahan kompos
dan surfaktan mampu mendegradasi kadar PAH secara
signifikan, kecuali pada reaktor dengan penambahan sampah
segar dan kompos jadi. Reaktor dengan penambahan sampah
setengah jadi mampu meningkatkan biodegradasi PAH sebesar
65,94% dibandingkan terhadap reaktor kontrol. Sementara
reaktor dengan penambahan surfaktan 2% dan 4% secara
berturut-turut mampu meningkatkan persentase biodegradasi
sebesar 33,35% dan 54,62%.
===================================================================================================
The soil around coal mining area in Tapin regency, South
Kalimantan, contains high concentration of Polycyclic Aromatic
Hydrocarbon (PAHs). PAHs is a group of organic compounds,
which is classified as recalcitrant with carcinogenic property. This
compound can increase the risk of gene mutation. The aims of
this study are (1) to determine the effect of surfactant on PAHs
biodegradation through co-composting method, (2) to determine
the effect of compost stability on PAHs biodegradation through
co-composting method, and (3) to determine the removal
efficiency of PAHs during the co-composting process.
This study was conducted for 60 days in laboratory scale.
Two variables were used in this experiment, namely different
concentrations of biodegradable surfactant (Tween 80)
application and different ages of compost materials. Tween 80
was applied at 0, 2, and 4 % w/w concentrations. Fresh yard
waste, half done, and mature compost materials were applied in
different reactors. The raw materials for the bioremediation
process were composed of PAHs-contaminated soil and compost
material of 50:50 w/w ratio.
This study showed that the addition of compost and
surfactant was able to decrease PAHs level significantly, except
in reactors where yard waste and mature compost were used.
Application of half done compost was able to increase PAHs
removal up to 65.94% compared to that in the control reactor. The
addition of Tween 80 of 2% and 4% concentrations were able to
increase PAHs removal to 33.35% and 54.62% respectively.
