Abstract

Kandungan karbohidrat yang tinggi dan lignin yang rendah dari makroalga Ulva sp. merupakan keunggulannya sebagai substrat untuk memproduksi biogas. Biogas dapat dihasilkan melalui proses biodegradasi anaerobik menggunakan metode batch. Penelitian ini bertujuan untuk mengetahui potensi biogas dan gas metana (CH4) yang dihasilkan Ulva sp. dalam sistem batch. Penelitian dilaksanakan dari bulan Desember 2013 sampai Juli 2014 di Laboratorium Pusat Penelitian Surfaktan dan Bioenergi Institut Pertanian Bogor, Laboratorium Pengujian Departemen Teknologi Industri Pertanian IPB dan Laboratorium Pengelolaan Limbah Agroindustri Universitas Lampung. Penelitian ini diawali dengan analisis proksimat, kemudian pembuatan starter dari kotoran sapi, dilanjutkan dengan aklimatisasi dan proses biodegradasi anaerobik yang menggunakan metode batch. Hasil dianalisis menggunakan program statistik SPSS 17. Hasil analisis proksimat menunjukkan bahwa Ulva sp. memiliki kadar air 16,7%, kadar abu 14,9%, lemak 2,9%, karbohidrat 60,3%, protein 5,3%, lignin 4,6%, Total Organic Carbon (TOC) 26,1%, dan Nitrogen 1,3% serta rasio C/N 20,5. Setelah proses aklimatisasi, biogas yang dihasilkan dari 8,8 L biomassa Ulva sp. sebesar 70,9 L dengan rentang pH 6,3–7,1 sedangkan pada proses biodegradasi anaerobik metode batch dari 4 kg Ulva sp. dihasilkan biogas sebesar 153,9 L dengan kandungan metana 51,1 L. Berdasarkan hasil penelitian ini diketahui bahwa setiap kg Ulva sp. berpotensi menghasilkan biogas sebesar 38,5 L dengan kandungan metana 12,8 L. Hubungan antara COD dan volume gas metana yang terakumulasi yaitu -0,971.

Abstract

Sago industry is one of the industries that generate wastewater with high levels of pollution load. High load of the wastewater can be reduced by anaerobic digestion methods. However, phenolic compounds derived from the sago trunk cause problems on the activity of microorganisms in anaerobic digestion. The purposes of this research were to select source of microorganisms which capable to decompose organic matter and to know their capabilities on biogas production from sago industrial wastewater. Sources of microorganisms used in this study were sludge from WWTP of sago industry, and  microorganism, commercially known as Activated Growth and BioCK.  Sago industry wastewater were fermented in stirred bioreactor. Each bioreactor contained 20% source of microorganisms and 80% of sago industry wastewater.  Each treatment was adapted for 7 days and value of pH, SCOD, Total Suspended Solid (TSS), Volatile Suspended Solid (VSS) and the gas volume was analyzed on the eight day. The result showed that the best source of microorganisms which was capable of degrading organic matter from sago industry wastewater  into biogas  was the sludge from WWTP of sago industry. With  the Hydraulic Retention Time (HRT) of 66 days, the sludge from WWTP of sago industry was able to  reach 55.79% SCOD removal, biogas production of 200 mL, pH value of 5.75, TSS 17 187 mg / L, VSS 12 296 mg / L, ratio of VSS / TSS 0.7129 mgVSS / mgTSS, Keywords : biogas, phenolic, sago, SCOD removal, sludge, wastewater

Abstract

Palm oil mill effluent (POME) waste water contains high consentration of organic pollutants. Anaerobic treatment is suitable to reduce the pollutans and also produce methane as one of renewable energy sources. Anaerobic degradation is complicated and sensitive process to the environtment, such as temperature and organic consentration. This study aims to determine characteristic of palm oil mill waste water treatment using semicontinue anaerobic CIGAR bioreactor. The seed was collected from sludge of anaerobic pond at POME treatment facility of PTPN VII Bekri. The substrat used in this experiment was fresh POME from the same mill. Initially, 4,375m3 of sludge was introduced into the bioreactor. The seed was acclimatized at a loading rate of 50 l/day for about a week. Anaerobic treatment was conducted at room temperature and the substrat was fed semicontinuelly at a loading rate of 100 to 350 liter/day. Results showed, that the stability of anaerobic degradation was achieved at an organic loading rate (OLR) of 0,9-3,11 kg/m3/day with COD removal more than 90% and maximum biogas production of 2,59 m3/day. Keywords : palm oil mill effluent, anaerobic bioreactor, COD removal, biogas.

Abstract

Sugarcane industries produce wastewater with high levels of pollution load. Wastewater pollutant load can be lowered by treating wastewater in the WWTP. Wastewater treatment process using Biological conventional system still has the disadvantage of increasing the pH of the waste water at a given time. It causes algae blooming. Algae population levels increases due to nutrients in wastewater. To prevent algae  from blooming, nutrient concentration in the waste water should be reduced. This study was aimed to measure the effectiveness of Waterhyacinth in lowering pollutant load of sugar cane industrial wastewater. The method used was to plant Waterhyacinth in aeration pond number 2 of WWTP and then taking samples at four locations and consists of point I (inlet pond aeration 2), point A (before the water hyacinth plant), point B (after the water hyacinth plant), the point C (waste pond outlet monitor). Parameters measured included pH, TSS, COD, NH4, and NO3. The result showed the wastewater treatment system using water hyacinth plant reduced the pollutant load sugar cane industrial wastewater at the rate of  0,000858%/m2 day, 0,010997%/m2 day, 0,008691%/m2 day, 0,005936%/m2 day, and 0,015016%/m2 day, respectively. These conditions indicate planting hyacinth was effective in lowering the level of industrial wastewater pollutant load of sugar cane.

Kegiatan kerekayasaan pengembangan bioreaktor sistem CoLAR ini bertujuan untuk menyediakanbiogas sebagai energi terbarukan di lingkungan industri tapioka. Bioreaktor sistem CoLAR terbuat dari bahan geomembran dengan kapasitas 3.600 m3 mampu menampung air limbah dengan laju alir150 m3 per hari. Air limbah akan mengalami proses fermentasi anaerobik dengan waktu tinggal hidrolik selama 20 hari. Hasil pengamatan pada uji kinerja bioreaktor diketahui bahwa bioreaktor CoLAR yang diterapkan dapat bekerja dengan baik. Hal ini ditandai dengan menurunnya nilai rata-rata Total Chemical Oxygen Demand (T-COD) sebesar 70,3 %, yaitu dari 9.011 mg/liter turun menjadi 2.680 mg/liter atau sebesar 0,317 gr COD/Liter/hari atau 949,6 kg COD/150 m3/hari. Sistem bioreaktor mampu menghasilkan rata-rata produksi biogas sebesar 485,4 m3/hari dengankandungan metana sebesar 58,8 %. Kualitas biogas tersebut secara teknis dapat digunakan sebagai sumber energi terbarukan.

Abstract

The purpose of this study is to develop a family-size biogas-fueled electricity generating system consisting of anaerobic digester, bio-filter scrubber, and power generating engine. Biogas was produced from a pilot scale wet anaerobic digester (5-m3 capacity). The biogas was filtered using bio-scrubber column filled with locally made compost to reduce hydrogen sulfide (H2S) content. Biogas composition was analysed using a gas chromatograph and its H2S level was measured using a H2S detector. A 750-W four stroke power generating engine was used with 100% biogas. Biogas consumed by the generator engine was measured at different load from 100 to 700 W (13.3 to 93.3% of the rated power). Three replications for each load experiment were taken. Results showed that the total biogas yield was 1.91 m3/day with methane content of 56.48% by volume. Bio-filter successfully reduced H2S content in the biogas by 98% (from 400 ppm to 9 ppm). Generator engine showed good performance during the test with average biogas consumption of 415.3 L/h. Specific biogas consumption decreased from 5.05 L/Wh to 1.15 L/Wh at loads of 100 W to 700 W, respectively. Thermal efficiency increased with loads from 6.4% at 100 W to 28.1 at 700 W. The highest thermal efficiency of 30% was achieved at a load of 600 W (80% of the rated power) with specific biogas consumption of 1.07 L/Wh.Article History: Received Janury 16th 2017; Received in revised form 2nd June 2017; Accepted 18th June 2017; Available onlineHow to Cite This Article: Haryanto, A., Marotin, F., Triyono, S., Hasanudin, U.
