Abstract

Pencemaran tanah akibat kerosin merupakan masalah lingkungan serius yang memerlukan penanganan segera karena sifat toksisitasnya. Metode soil washing dengan penambahan surfaktan terbukti efektif sebagai teknik remediasi ex-situ untuk memisahkan kontaminan hidrofobik dari partikel tanah. Penelitian ini bertujuan untuk menganalisis pengaruh tingkat pencemaran (5%, 10% dan 15% w/w) terhadap efisiensi removal Total Petroleum Hydrocarbon (TPH), menganalisis efektivitas tiga jenis surfaktan yaitu anionik (Sodium Dodecyl Sulfate/SDS), kationik (Cetyltrimethylammonium Bromide/CTAB), dan non-ionik (Tween 80) dan pengaruh konsentrasi surfaktan 0,25% w/v dan 0,5% w/v terhadap efisiensi removal TPH serta menentukan waktu kontak minimum untuk mencapai kadar TPH dibawah 4.500 mg/kg. Penelitian ini dilakukan dalam skala laboratorium menggunakan tanah tercemar bertekstur sand. Proses soil washing dilakukan pada kecepatan putaran 200 rpm dengan waktu kontak 1 jam. Parameter yang diukur adalah efisiensi removal TPH dengan metode gravimetri menggunakan pelarut organik n-heksan. Data hasil dianalisis menggunakan uji statistik Three-Way ANOVA untuk menganalisis pengaruh faktor-faktor yang diuji. Hasil penelitian menunjukkan tingkat pencemaran 5%, 10%, dan 15% w/w berpengaruh signifikan terhadap efisiensi removal TPH sebesar 95,69%, 93,97%, dan 91,04%. Efisiensi tertinggi dihasilkan CTAB (96,19%), diikuti SDS (93,53%) dan Tween 80 (91,01%). Tween 80 lebih direkomendasikan karena toksisitas rendah dan biodegradabilitas tinggi. Peningkatan konsentrasi 0,25% w/v (92,91%) ke 0,5% w/v (94,29%) tidak berpengaruh signifikan. Waktu kontak minimum mencapai kadar TPH dibawah 4.500 mg/kg adalah 50 menit.

Soil contamination from kerosene is a serious environmental problem that requires immediate action due to its toxicity. The soil washing method with the addition of surfactants has proven effective as an ex-situ remediation technique for separating hydrophobic contaminants from soil particles. This study aimed to analyze the effect of contamination levels (5%, 10%, and 15% w/w) on the removal efficiency of Total Petroleum Hydrocarbons (TPH). The study also analyzed the effectiveness of three types of surfactants: anionic (Sodium Dodecyl Sulfate/SDS), cationic (Cetyltrimethylammonium Bromide/CTAB), and non-ionic (Tween 80). The effect of surfactant concentrations of 0.25% w/v and 0.5% w/v on TPH removal efficiency was also analyzed. The study was conducted on a laboratory scale using contaminated sandy soil. The soil washing process was carried out at a rotation speed of 200 rpm with a contact time of 1 hour. The parameter measured was the TPH removal efficiency using the gravimetric method using the organic solvent n-hexane. The data were analyzed using a three-way ANOVA statistical test to analyze the influence of the tested factors. The results showed that contamination levels of 5%, 10%, and 15% w/w significantly affected the TPH removal efficiency, reaching 95.69%, 93.97%, and 91.04%, respectively. The highest efficiency was achieved by CTAB (96.19%), followed by SDS (93.53%) and Tween 80 (91.01%). Tween 80 is preferred due to its low toxicity and high biodegradability. Increasing the concentration from 0.25% w/v (92.91%) to 0.5% w/v (94.29%) had no significant effect. The minimum contact time to achieve TPH levels below 4,500 mg/kg was 50 minutes.
