Abstract

Penelitian ini fokus pada penyisihan hidrokarbon pada tanah tercemar crude oil menggunakan metode co-composting dalam skala laboratorium. Sampel tanah tercemar diambil dari Pertambangan Minyak Bumi Rakyat Wonocolo, Bojonegoro. Penelitian ini bertujuan untuk menentukan kadar hidrokarbon pada sampel tanah tercemar crude oil , menentukan kemampuan metode co-composting aerobik menggunakan sampah organik biodegradable yang berasal dari kebun dan rumah potong hewan (RPH) dalam penyisihan hidrokarbon, dan menentukan jenis sampah organik biodegradable yang menghasilkan efisiensi penyisihan hidrokarbon yang optimum pada tanah tercemar crude oil dengan metode co-composting aerobik. Penelitian ini menggunakan reaktor kaca dengan dimensi 14,9 cm (d) x 26,9 cm (t). Ada 13 perlakuan, termasuk kontrol, setiap perlakuan menggunakan 2 kali pengulangan sehingga jumlah total reaktor 26 buah. Co-composting dilakukan pada kondisi aerobik. Pengadukan manual untuk aerasi dilakukan setiap 3 hari sekali. Nilai dari kadar hidrokarbon, C-organik, TKN, N-nitrat, N-nitrit, dan total populasi bakteri diukur setiap 20 hari sekali. Suhu diukur setiap hari. Kadar air dan pH diukur setiap 3 hari sekali. Pengaruh jenis sampah organik dan komposisi tanah tercemar crude oil dan sampah organik terhadap tingkat penyisihan hidrokarbon dianalisis dengan metode uji Anova Two-way. Hasil penelitian menunjukkan bahwa kadar hidrokarbon pada sampel tanah tercemar crude oil adalah sebesar 6,05%. Pada hari ke-60, penyisihan hidrokarbon paling efektif terjadi pada reaktor dengan komposisi 50% tanah tercemar crude oil dan 50% campuran sampah kebun dan rumen sapi (S/R50). Pada reaktor ini, hidrokarbon yang tersisihkan yaitu dari 5,37% sampai 2,77% dengan efisiensi penyisihan sebesar 33,32%. Berdasarkan hasil uji statistik Anova Two-way juga diketahui bahwa tidak ada pengaruh signifikan variasi jenis sampah organik, variasi komposisi tanah dan sampah, dan interaksi kedua variasi terhadap tingkat penyisihan hidrokarbon (P>0,05). Co-composting sampai hari ke-60 pada reaktor S/R50 dapat mereduksi C-organik dari 24% menjadi 3,68% dan rasio C/N dari 34,4 menjadi 2,46. Co-composting sampai hari ke-60 pada reaktor S/R50 juga dapat menaikkan total populasi bakteri dari 3,026 x 1010 CFU/g menjadi 2,184 x 1015 CFU/g dan N-total dari 0,70% menjadi 1,50%. =========================================================================================================== This research was focused on the removal of hydrocarbons in crude oil contaminated soil using co-composting method in a laboratory scale.The soil samples were collected from a traditional oil mining site in Wonocolo District, Bojonegoro. The aims of the research were: (1) to determine the level of hydrocarbon pollutants in soil samples; (2) to determine whether aerobic co-composting method using solid waste from yards and slaughter house could remove hydrocarbon pollutant (3) to determine most suitable yard waste and slaughterhouse waste composition in removing hydrocarbon pollutant by aerobic co-composting method. Glass reactors of 14.9 cm (d) x 26.9 cm (h) dimensions were used in this study. During this study 13 treatments were applied including controls, with two repetitions for each treatment. Therefore, the total number of reactors was 26. The co-composting process was carried out in aerobic condition. Manual mixing for aeration was applied every 3 days. The levels total petroleum hydrocarbons (TPH), organic C, TKN, nitrate-N, nitrite-N, and total bacterial count were measured every 20 days. Temperature was measured daily. Water content and pH was measured every 3 days. Effects of the compositions of biodegradable organic waste and crude oil contaminated soil on hydrocarbon removal was analyzed using Anova Two-way. The results showed that average TPH concentration in the soil samples was 6.05%. On 60th day, the effective hydrocarbon removal occured in the reactor with a composition of 50% crude oil contaminated soil and 50% mixture of garden waste and slaughterhouse waste (S/R50). In this reactor the TPH was removed from 5.37% to 2.77% (33,32% removal efficiency). Based on the results of Anova Two way statistical tests was also known that there wasn’t a significant effect of variations the type of organic waste, variations in soiland organic waste composition, and interaction of both variations to hydrocarbons removal (P>0.05). Until the 60th day, the organic C was reduced from 24% to 3.68% and the C/N ratio was decreased from 34.4 to 2.46. Additionally, the total bacterial count increased from 3,026 x 1010 CFU/g to 2.184 x 1015 CFU/g and total-N increased from 0.70% to 1.50%.
