Abstract

Increasing of textile industries creates a critical need for a proper treatment plan to control and minimize possibilities of contaminants and toxic compounds being released to the environment. Biological approaches by utilizing microorganisms, although because in the rise of practicality and cost-effectiveness, are still flawed and require more analysis and development. One of such approach that is often being researched is the utilization of biofilm for treating industrial waste, and among those is about the use of fungal and bacterial consortium. This research was conducted to examine and acquire a more stable biofilm formed by fungal and bacterial consortium for decolorization process of textile wastewater. Isolates were selected by examining their decolorization capability, antagonistic activity, and mixed culture formation (consortium). The selection continued with biofilm forming in material plastic LLDPE. Superior consortium from bacteria and fungi in the form of biofilm in material plastic LLDPE then was applied for the decolorization of Vat Violet 1 dye from textile industrial wastewater. The selection resulted in twosuperior fungal isolates coded as strain JYGC1 and K2; and three bacterial isolates were coded as strain ATA6, PK29, and PK65. These isolates were then combined to form biofilm on the surface of material plastic LLDPE and examined for their applicability to decolorize wastewater containing Vat Violet 1 under variation of pH condition of 5, 7, and 8. Biofilm with regular thickness was formed by the fungal bacterial consortium and capable of increasing the rate of decolorization activity. The highest biomass yield before and after application to the wastewater was found to be at pH 7 at about 0.66 g and 0.45 g, respectively. The thickness and biomass corresponds with decolorization activity, which is also the highest on pH 7, with difference of 1.155 between before and after application; much higher than without biofilm application at 0.714.

Abstract

Anaerobic ammonium oxidation (anammox) is the process of converting ammonium directly into nitrogen gas with nitrite as an electron acceptor under anaerobic conditions. This process is more effective than conventional nitrification-denitrification but is very dependent on several parameters, one of which is temperature. The optimum temperature range for the growth of anammox bacteria is 30-400C. The purpose of this research was to determine the efficiency of nitrogen removal by anammox process using palm fibers in the Up-Flow Anaerobic Sludge Blanket (UASB) reactor in the tropical temperature. The experiment was conducted at a laboratory scale with a variation of Hydraulic Retention Time (HRT) 24 h and 12 h using artificial wastewater. The reactor was inoculated with anammox granule genus Candidatus Brocadia. The concentration of ammonium, nitrite, and nitrate in the influent and effluent were measured using a UV-Vis spectrophotometer based on standard method. Based on the experiment, the ratio ΔNH4+-N:ΔNO2--N and ΔNO3--N:ΔNH4+-N similar with stoichiometric of anammox. The maximum Nitrogen removal performance (NRT) achieved 0.11 kg-N/m3.d at Nitrogen Loading Rate (NLR) 0.14 kg-N/m3.d and 0.20 kg-N/m3.d at NLR 0.29 kg-N/m3.d. The removal efficiency for Ammonium Conversion Efficiency (ACE) and Nitrogen Removal Efficiency (NRE) in HRT 24 h were 79% and 76%, respectively while decreased in HRT 12 h were 72% and 69%, respectively. Anammox process can be applied in the tropical temperature at a laboratory scale using a UASB reactor with palm fiber as the carrier.

Abstract

The methods of microbial cells preservation were already known by liquid drying, freeze-drying, and freezing. Those methods could preserve bacteria cells in a long period of time but its survivability was relatively low and used relatively high energy during preservation. Immobilization was known as entrapping, attaching or encapsulating bacterial cells in a suitable matrix. This research was conducted to know the suitability of zeolite as immobilization carrier and also as preservation matrix of two halophilic archaea Haloferax chudinovii and Haloferax lucentense. Variable of this research was the type of the carrier which was raw zeolite, 110oC and 300oC heat-activated zeolite carrier, parameters measured in this study was physical and chemical of zeolite such as chemical content, Si/Al ratio, surface area and pore volume, and biochemical assay, bacterial cells numbers after immobilization and bacterial cells after preservation as bacterial response to the immobilization and preservation. Heat activation was significantly affecting the chemical composition, carrier surface area, and pore volume. Highest surface area, pore volume, and Si/Al ratio were obtained in 110oC pretreated zeolite followed by 300oC pretreated zeolite. The bacterial cells obtained after immobilization process was 1,8x107 cfu/g, 3,0 x 107 cfu/g, and 2,1x107 for raw zeolite, 110oC pretreated zeolite and 300oC zeolite respectively. After 4 months preservation, the slight reduction of the bacterial cells was observed. Immobilization halophilic archaeae using zeolite as carrier was proven as low cost and effective preservation method due to relatively simple process and unspecific preservation temperature requirements.

Abstract

Crumb rubber is one of Indonesia’s agroindustry export commodities. This industry faces environmental problems due to their wastes, both liquid and air. The source of air pollution is commonly from drying process that emitted odor from its evaporation and heating phenomena. Industry uses wet scrubber technology as air pollution control from emitted odor from drying process. Preliminary identification in noncontrolled wet scrubber shown that wet scrubber efficiency around 47%. Low efficiency wet scrubbing process causes rain drop of water vapor around drying process. This research used electrochemical based sensor MICS 5524 as ammonia monitoring instrument, assisted with arduino as microcontroller to regulate water discharge through valve controlling scrubbing process. This electrochemical based sensor reads ammonia based on voltage reads by Arduino microcontroller. Ammonia reading then control scrubbing process by adjusting valve opening for spray water distribution. Wet scrubber efficiency increases to 66,96% due to water scrubbing control, also can save water utilization as high as 61,90%, followed by absence of rain drop contains ammonia around drying process area.

Abstract

Direct utilization of biogas as a fuel often cause problems, i.e bad odor, metal corrosive, wall erosion and frequent fire extinguished. This is due to the presence of gas impurities in biogas such as H2S, NH3, CO2, H2, CO and water vapor (H2O), which will lower the value of calories from biogas and detrimental to the environment and health. The purpose of this research is to eliminate impurities gases, through a process called gas purification, until higher heat value of biogas is achieved. The methods were undertaken by adsorption process using activated carbon adsorbent with variable time contacts, to obtain the optimum adsorption power of activated carbon toward gas impurities that are present in wastewater. The results showed that removal/reduction of H2S of 99.99% was obtained from 4200 ppm to 0.22 ppm, NH3 removal reached 12.7%, from 94.96 ppm to 0.65 ppm, CO2 removal reached 77.48%, from 30,77% to 6.93%, water vapour (H2O) removal reached 97.95%, from 0.584 mg/L to 0.012 mg/L, which increased methane concentration (CH4) from 38.2% to 84.12%. This methane purification technology is renewable energy sources that is safe and environmentally friendly and also can be developed in other industries i.e tofu industries. The saturation of activated carbon adsorbents obtained after 48 hours. Adsorption of each impurities gas components by activated carbon are written as follows: 10.98 mg H2S/gram activated carbon/minute, 0.016 mg NH3/gram of activated carbon/minute, 0.090 CO2/gram activated carbon/minute.

Abstract

Minyak dan lemak merupakan parameter yang konsentrasi maksimumnya dipersyaratkan untuk air limbah industri dan air permukaan. Analisis infra merah dan gravimetri adalah dua metode standar yang hingga saat ini digunakan. Kelemahan metode-metode tersebut yaitu penggunaan pelarut CCl4(metode IR) dan daerah konsentrasi analisis yang besar (metode gravimetri) sehingga penting dilakukan penelitian penggunaan pelarut lain dan penurunan limit deteksi, khususnya metode gravimetri. Pelarut C2Cl4 dan S316 digunakan sebagai pelarut ekstraksi pada metode IR karena tergolong pelarut yang masih direkomendasikan untuk penggunaannya. Variasi volume sampel dan tahapan ekstraksi dengan n-heksan sebagai pelarut dilakukan untuk pengembangan metode gravimetri sehingga mampu menurunkan limit deteksi di bawah 10 mg/L. Jenis minyak yang digunakan sebagai sampel yaitu minyak nabati dan minyak mineral. Pada pembacaan absorbansi pelarut C2Cl4 dan S316 menunjukkan level respon yang sangat tinggi yaitu 18 mg/L (C2Cl4) dan 15 mg/L (S316) sehingga tidak bisa digunakan untuk analisis minyak dengan metode infra merah. Pada metode gravimetri diperoleh persen recovery 92,28% (sampel minyak nabati) dan 99,25% (sampel minyak mineral) dengan konsentrasi analit sebesar 0,9 mg/L dan 0,88 mg/L. Nilai persen recovery tersebut diperoleh pada volume sampel 2000 mL dan teknik ekstraksi 4 tahap dengan limit deteksi 0,5639 mg/L dan 0,4736 mg/L sehingga pengembangan metode gravimetri ini layak digunakan untuk analisis sampel air limbah dan air permukaan.

Abstract

High Volume Air Sampler (HVAS) adalah alat pengambil sampel partikulat di udara ambien yang memiliki prinsip kerja dengan sistem vakum dengan menarik udara lingkungan sekitar melalui inlet dengan ukuran-selektif dan melalui filter berukuran 20,3 x 25,4 cm (8” x 10”) pada laju alir 1.132 liter/menit. Pada standard US-EPA (United States Environmental Protection Agency) sering menemui alat sampling yang digunakan memiliki bentuk yang besar (45,5” x 22,5” x 20”) dan berat sekitar 15-20 kg, sehingga timbul ide penelitian untuk membuat desain modifikasi alat pengambil sampel partikulat ambien dengan bentuk yang lebih fleksibel, ringan dan ringkas dengan menggunakan metode uji Gravimetri. Tahap awal penelitian ini adalah melakukan identifikasi peralatan HVAS standard dan peraturan yang mengatur tentang pengujian partikulat. Kemudian merubah bentuk fisik luarnya (memperkecil) tanpa merubah fungsi yang ada didalamnya dan diuji coba bersamaan kinerjanya. Hasil uji coba diolah menggunakan statistik. Dengan menggunakan hasil identifikasi HVAS standard EPA, maka didapat desain modifikasi HVAS dengan dimensi unit utama 15,35” x 15,35” x 10” (PxLxT), kaki knockdown sepanjang 4,5” dari hollow 4x4cm sebanyak 12 buah, dan memiliki berat total sekitar 23 lbs / 10,58 kg.Keseluruhan proses pembuatan alat ini hanya memerlukan biaya sebesar Rp.11.350.000,-. HVAS modifikasi memiliki kemampuan yang tidak beda nyata dengan HVAS existing berdasarkan nilai Anova, dimana nilai P =0,985. HVAS modifikasi yang didesain telah memenuhi standard dengan bentuk lebih kecil dan lebih ringan, sehingga bisa memudahkan dalam penyimpanan dan mobilisasi pengujian sampel partikulat ambien. Berdasarkan penggunaan material untuk pembuatan HVAS modifikasi didapatkan angka yang lebih murah karena reduksi material pembentuk rangka HVAS. HVAS modifikasi dapat dipergunakan sebagai alat sampling untuk pengujian sampel partikulat di udara ambien.
