Abstract

Oil field produced water with a high fl ow rate usually contains suspended solid, such as corrosion, scale, bacteria, clay, wax, and oil residue. Biocide is used to reduce viability of bacteria cell in produced water reused for produced water reinjection into oil reservoir. The objectives of this study is to examine anti bacteria activity of fi ve active compound biocides i.e. Glutaraldehide (Biocide-1), Aldehyde-Based and Surfactants (Biocide-2), Glutaraldehyde, Quartenary Ammonium Compounds (Biocide-3), Tetrakis Phosphonium Hydroxymethyl Sulfate (Biocide-4), and Amine Aldehide (Biocide-5) for reduced bacteria cell in produced water in this fi eld. Resulted in this study is general aerobic bacteria group is high contamination at the produced water reinjection. Bacteria isolates identifi ed is Bacillus sp (2 types of isolates) and Pseudomonas alcaligenes. The type of Biocides-2 and Biocide-3 reduced the number of bacteria cells maximal at a concentration of 200 ppm.Oil field produced water with a high fl ow rate usually contains suspended solid, such as corrosion,scale, bacteria, clay, wax, and oil residue.

Abstract

Bioremediation is a method which can be used to reduce the amount of pollutants or toxic substances that damage the environment through the use of microorganisms to remove the contaminants. The purpose of this research is to determine the effects of petrofilic microorganisms and bulking agent on the enhancement of hydrocarbon’s biodegradation efficiency, soil water content, growth rate of petrofilic bacteria and Azotobacter vinelandii. Nine treatments in this research were a petrofilic consortium (Pseudomonas spp., Actinomycetes sp., and petrofilic fungi) and Azotobacter vinelandii (biosurfactan), as well as bulking agent (rice husk charcoal and baglog waste of Oyster Mushrooms). The experiment design used was a randomized block design with three replications, so there were 27 experimental units (microscosmos). The result was that the application of petrofilic microorganisms and bulking agent is the best treatment to enhance the efficiency of hydrocarbon’s biodegradation, the growth rate of petrofilic bacteria, and soil water content. The petrofilic consortium treatment with the highest value of biodegradation efficiency reached 83,9%.

Abstract

Penelitian ini bertujuan untuk mengetahui senyawa yang paling efektif untuk menghidrolisis kulit ari kedelai dalam menghasilkan gula sebagai bahan baku fermentasi bioetanol. Metode yang digunakan adalah eksperimen dengan menggunakan rancangan acak kelompok yang terdiri atas dua faktor. Faktor pertama adalah jenis senyawa yang digunakan dalam proses hidrolisis yaitu senyawa asam dan basa yang terdiri dari H2SO4,HCl, NaOH, dan NH3. Faktorkedua adalah konsentrasi senyawa penghidrolisis 0,2%, 0,4%, 0,6%, 0,8% dan 1% (v/v) dengan masing-masing perlakuan digunakan pengulangan sebanyak 4 kali. Parameter yang diukur adalah kandungan gula reduksi hasil hidrolisis, dengan data sekunder yaitu kandungan selulosa dan hemiselulosa serta berat jenis etanol. Data konsentrasigula reduksi hasil hidrolisis dari limbah kulit ari kedelai dianalisis dengan uji anava dua arah. Hasil analisis anava menunjukkan bahwa senyawa penghidrolisis terbaik dalam menghidrolisis limbah kulit ari kedelai adalah HCl dengan konsentrasi optimum 0,4%. Serta terdapat interaksi perlakuan senyawa penghidrolisis serta konsentrasinya terhadap konsentrasi gula reduksi (mg/mL) yang dihasilkan dari hidrolisis limbah kulit ari kedelai. Uji post-hoc menunjukkan bahwa senyawa HCl 0,4% menghasilkan konsentrasi gula reduksi tertinggi, yaitu 31,23 mg/mL. This study aims to determine the most effective solvent used to hydrolyze soy husk waste to produce reducing sugar as a feedstockl for bioethanol fermentation. The method used is experiment using a randomized block design consisting of two factors. The first factor is the type of compounds used in the hydrolysis process, comprising acidand base compounds: H2SO4, HCl, NaOH, and NH3. The second factor is the concentration of hydrolyze compound0.2%, 0.4%. 0.6%, 0.8%, and 1% (v/v) and every treatment repeated 4 times. Measurement parameters content of reduced sugar, hydrolysis product, and secondary data that content of cellulose and hemicellulose also the density of ethanol. Concentration of reducing sugar from hydrolysis of soybean husk is analyzed by two-way ANOVA test. ANOVA analysis result indicate that the best hydrolysis compounds in hydrolizing soybean husk is HCl with the optimum concentration is 0,4%. And there are interactions between treatment of compound used to hydrolyze as well as concentration on reducing sugar concentration (mg/mL) as product from soybean husk waste hydrolysis. Post-hoc test showed that 0,4% HCl produce the highest concentration of reducing sugar at 31.23 mg/mL.

Abstract

Pemulihan tanah terkontaminasi minyak dan pengolahanlimbahberminyak di industri minyak diperlukan oil separation technology yang tepat dan tidak menimbulkan masalah lain. Dalam beberapa kasus, tanah yang terkontaminasi banyak mengandung minyak dan dalam pengelolaannya hanya dikirimkan ke unit pengolahan limbah B-3. Salah satu teknik yang dikembangkan oleh LEMIGAS adalah menggunakan teknik yang terintegritas yaitu menggabungkan pengolahan secara fisika, kimia, dan biologi. Minyak yang masih terdapat dalam tanah dipisahkan dari impuritisnya, seperti tanah, pasir, dan padatan lainnya. Melalui proses pemulihan ini diharapkan minyak yang masih terdapat dalam tanah dapat direduksi sampai batas yang diizinkan oleh peraturan. Di samping itu untuk pengolahan limbah berminyak masih dapat diambil kembali minyaknya sebanyak mungkin (oil recovery). Dari hasil ujicoba skala demo plantunit pada lokasi yang mengandung tanah terkontaminasi, TPH 24,71% dapat direduksi menjadi 0,91%. Selain itu unit tersebut mampu memulihkan limbah berminyak lebih dari 95%. Remediation of oil contaminated soil and oily wastewater treatment in the oil industry requires proper oil separation technology and does not cause any other problems. In some cases, contaminated soil still contains much oil and in the management is only delivered to the B-3 waste treatment unit. One of the techniques developed by LEMIGAS is to use an integrated technique that combines physical, chemical, and biological processing. Oil still in the soil is separated from the impurities, such as soil, sand, and other solids. Through this recovery process it is expected that the oil still present in the soil can be reduced to the extent permitted by the regulation. In addition to the treatment of oily waste can still be recovered as much oil (oil recovery). From the results of a demonstration scale of demo plant unit on a site containing contaminated soil, TPH 24.71% can be reduced to 0.91%. In addition the unit is able to recover oily waste more than 95%.
