ABSTRAK
Kegiatan eksploitasi dan eksplorasi minyak bumi yang semakin tinggi
menghasilkan residu yang mencemari lingkungan. Salah satu upaya pemulihan
tanah terkontaminasi minyak bumi dapat dilakukan dengan pengolahan biologis
yaitu bioremediasi secara ex-situ menggunakan metode composting. Penelitian ini
bertujuan untuk mengetahui pengaruh kadar kontaminan terhadap aktivitas mikroba
pada perombakan Total Petroleum Hidrokarbon (TPH), penambahan pupuk
kandang sapi dan pupuk kompos daun bambu terhadap perombakan TPH, dan
interaksi antara kadar kontaminan dengan penambahan jenis pupuk terhadap
perombakan TPH. Penelitian dilakukan menggunakan rancangan penelitian
Rancangan Acak Lengkap (RAL) dua faktor. Faktor pertama kadar minyak bumi
atau kontaminan pada konsentrasi TPH 0%; 4,3%, dan 9%. Faktor kedua jenis
bahan organik yaitu pupuk kandang sapi dan pupuk kompos daun bambu. Penelitian
dilakukan menggunakan wadah yang diisi dengan 1 kg bahan dengan waktu
inkubasi selama 30 hari. Parameter yang diamati berupa TPH, pH, C/N Rasio, kadar
C-Organik, kadar N-Total, dan evolusi CO2. Data dianalisis menggunakan Analysis
of Variance (ANOVA) dan untuk mengetahui beda nyata antara perlakuan
digunakan Duncant Multiple Range Test (DMRT) pada taraf 5%. Hasil penelitian
menunjukkan bahwa kadar kontaminan berpengaruh nyata terhadap aktivitas
mikroba pada perombakan TPH. Kadar kontaminan 9% menunjukkan aktivitas
mikroba yang tinggi dengan hasil evolusi CO2 sebesar 31,33 mg/25 g/3 hari.
Penambahan pupuk kandang sapi dan pupuk kompos daun berpengaruh nyata
terhadap perombakan TPH, pupuk kandang sapi menunjukkan hasil perombakan
yang lebih baik. Terjadi interaksi antara kadar kontaminan dengan penambahan
jenis pupuk terhadap perombakan TPH. Perlakuan tanah tercemar 9% dan pupuk
kandang sapi (C2P1) memberikan hasil terbaik dengan persentase penurunan TPH
71,78 % dengan kadar awal TPH sebesar 9% menjadi 2,5%.

ABSTRACT
Increasinly exploitation and exploration activities of petroleum can produce
residues which pollute the environment. One of the efforts to restore oil�contaminated soil can be conducted by biological treatment that is ex-situ
bioremediation using the composting method. The aim of this study was to
determine the effect of contaminant levels on microbial activity in to decrease the
Total Petroleum Hydrocarbons (TPH), addition of cow manure and bamboo leaf
compost to decrease the TPH, and the interaction between contaminant levels and
the addition of fertilizer types to decrease the TPH. Furthermore, the study was
conducted by using a two-factor Completely Randomized Design (CRD) research
design. The first factor was the level of petroleum or contaminants at a TPH
concentration of 0%; 4.3%, and 9%. Meanwhile, the second factor was the type of
organic matter that were cow manure and bamboo leaf compost. The study was
conducted by using a container filled with 1 kg of material with 30 days of
incubation time. Parameters observed were TPH, pH, C-Organic, N-Total, C/N
Ratio and CO2 evolution. Data were analyzed by using analysis of variance
(ANOVA) while in order to determine the significant difference between
treatments, Duncant Multiple Range Test (DMRT) was used at the 5% level. The
results showed that the level of contaminants had a significant effect on microbial
activity in the decomposition of TPH. Contaminant levels of 9% showed high
microbial activity with CO2 evolution of 31.33 mg/25 g/3 days. The addition of cow
manure and leaf compost had a significant effect on the decomposition of TPH, cow
manure shows better results. There was interaction between the levels of
contaminants and the addition of fertilizers to the TPH decomposition. Combination
treatment between 9% contaminated soil and cow manure (C2P1) had the best
results with a decrease in TPH percentage of 71.78% with an initial TPH content of
9% to 2.5%.
