Abstract
Pencemaran minyak bumi pada tanah menjadi ancaman
serius bagi kesehatan manusia. Minyak bumi dapat mencapai lokasi
sumber air tanah sehingga dapat mencemari air tanah yang
digunakan sebagai sumber utama kebutuhan air bersih. Senyawa
hidrokarbon yang terkandung pada minyak bumi juga merupakan
senyawa yang paling sulit diurai. Salah satu cara menanggulangi
permasalahan ini adalah dengan bioremediasi, yaitu pemulihan
kondisi lingkungan dengan memanfaatkan aktivitas biologis
mikroorganisme untuk menurunkan kadar toksisitas dari senyawa
pencemar.
Penelitian dilakukan dalam skala laboratorium selama 30 hari.
Bioremediasi tanah tercemar minyak bumi menggunakan metode
biostimulasi dengan pupuk NPK sebagai nutrien. Sebelum dilakukan
bioremediasi, dilakukan pre-treatment berupa soil washing dengan
surfaktan tween-80 untuk menurunkan kandungan total petroleum
hidrokarbon (TPH) sesuai dengan KEPMEN LH No 128 Tahun 2003.
Variasi yang dilakukan adalah kadar pemberian pupuk NPK sebagai
nutrien ke dalam tanah tercemar (kontrol, 10%, dan 20%) serta
penambahan kadar oksigen ke dalam sampel tanah (aerasi dan
tanpa aerasi). Parameter yang diuji meliputi nilai TPH, suhu, pH serta
total koloni mikroba yang terkandung sampel tanah tercemar.
Hasil penelitian menunjukkan bahwa adanya pre-treatment
soil washing dapat membantu menurunkan TPH hingga mencapai
4,55%. Pada bioremediasi dengan metode biostimulasi, hasil yang
didapatkan menunjukkan bahwa penambahan nutrien 20%
menghasilkan tingkat degradasi TPH paling tinggi (turun hingga
4,23%) pada sampel tanah tercemar. Sedangkan pada penambahan
aerasi, hasil uji statistik two-way anova menunjukkan adanya
penambahan aerasi pada bioremediasi tidak berpengaruh signifikan
terhadap hasil penurunan nilai TPH dikarenakan nilai sig > 0,05.

Petroleum contamination in the soil pose a serious threat to
human health. Petroleum is able to reach the location of groundwater
resources that can contaminate groundwater used as a main source
of clean water needs. Hydrocarbon compounds contained in the
petroleum is also the most difficult to disentangle compound. One
way of overcoming this problem is to bioremediation, which is the
restoration of environmental conditions by utilizing the biological
activity of microorganisms to reduce levels of toxicity of pollutant
compounds.
The study was conducted in laboratory scale for 30 days.
Bioremediation of petroleum-contaminated soil using a biostimulation
method with NPK fertilizer as nutrient. Before to bioremediation,
performed pre-treatment such as soil washing with a tween-80
surfactant to reduce the content of total petroleum hydrocarbons
(TPH) in accordance with KEPMEN LH No 128 Tahun 2003. The
variation of research is concentration NPK fertilizer nutrients in
contaminated soil (control, 10%, and 20%) and increasing the
oxygen levels in contaminated soil samples (aeration and without
aeration). The parameters tested include TPH value, temperature,
pH and total microbial colonies that contained at contaminated soil
samples.
The results showed that the pre-treatment of soil-washing can
help TPH lower up to 4.55%. In the bioremediation with
biostimulation method, the results obtained showed that the addition
of nutrients 20% produce the highest levels of TPH degradation
(down to 4.23%) in contaminated soil samples. While the addition of
aeration, the statistical test ANOVA two-way showed the addition of
aeration at bioremediation no significant effect on the results of
impairment TPH because significant value > 0.05.
