Abstract

ABSTRACTPalm Oil Mill wastewater or POME is currently not fully utilized. POME waste treatment generally uses covered lagoon technology using the anaerobic system, which generally operates well in neutral waste conditions with a pH of 7 and uses mesophilic processes at temperatures around 35oC. So it is necessary to cool down and neutralize before POME is fed to the reactor, by mixing it with POME which has been degraded inside the reactor, where the pH condition has to turn into a base. It is useful to ensure that the POME temperature before being fed into the reactor is near the ambient temperature and the acidity of POME is near neutral (pH = 7). POME treatment using a covered lagoon reactor usually need 30 days residence time. The Fixed Bed anaerobic reactor is capable to treat waste with a low pH waste, so POME which has a pH of 4 does not need to be neutralized before treating using Fixed Bed Reactor. This will simplify the processing process, reduce investment costs and operating costs. The purpose of this research is to process POME waste using an anaerobic type Fixed Bed reactor without neutralization stage. The method processing using Fixed Bed type reactor is divided into two stages of a process that is bacteria inoculation process and POME waste adaptation process. The results of the research can reduce the HRT to 2o days, with optimal POME feeding at 150 liters/day. The percentage of methane gas measured was 66%. The methane gas yield is 0.52 liters/gram of COD or greater than the results of using the covered lagoon, which is 0.35 liters/ gram COD.Key word: Palm Oil Mill Effluent (POME), anaerobic, Fixed Bed, biogas, neutralizationABSTRAKLimbah cair industri minyak kelapa sawit atau POME saat ini belum dimanfaatkan secara maksimal. Pengolahan limbah POME umumnya menggunakan teknologi covered lagoon dengan sistem anaerobik, dimana umumnya teknologi ini beroperasi baik pada kondisi limbah yang netral dengan pH 7 dan menggunakan proses mesopilik pada suhu sekitar 35oC.  Sehingga diperlukan tahap pendinginan dan tahap netralisasi terlebih dahulu sebelum POME diumpankan ke reaktor, yaitu dengan mencampurkannya dengan POME yang sudah terdegradasi di dalam reaktor, karena sifatnya  sudah berubah menjadi basa. Hal ini berguna untuk memastikan bahwa suhu POME sebelum masuk reaktor sudah mendekati suhu lingkungan dan tingkat keasaman POME sudah mendekati netral (pH =7). Pengolahan POME menggunakan covered lagoon umumnya memerlukan waktu tinggal di dalam reaktor(HRT) sekitar 30 hari. Reaktor anaerobik tipe Fixed Bed mampu mengolah limbah dengan pH rendah, sehingga POME yang mempunyai pH 4, tidak perlu dinetralkan terlebih dahulu. Hal ini akan menyederhanakan proses pengolahan, menurunkan biaya investasi dan biaya operasi. Tujuan penelitian ini adalah mengolah limbah POME dengan menggunakan reaktor anaerobik tipe Fixed Bed tanpa tahap proses netralisasi. Metode pengolahan anaerobik dengan menggunakan reaktor tipe Fixed Bed, terbagi menjadi dua tahapan proses yaitu proses inokulasi bakteri dan proses adaptasi limbah POME. Hasil penelitian dapat menurunkan HRT menjadi 20 hari, dengan pengumpanan POME optimal pada 150 liter/hari. Persentase gas metana adalah 66%. Hasil produksi gas metana adalah 0,52 liter/gram COD atau lebih besar dari hasil proses menggunakan covered lagoon, yaitu 0,35 liter/ gram COD.Kata Kunci: Palm Oil Mill Effluent (POME), anaerobik, Fixed Bed, biogas, netralisasi

Abstract

ABSTRACT Palm Oil Mill Effluent (POME) resulted from the palm oil industry is a potential resource for biogas production. In this study, POME was processed by utilizing microbes in an anaerobic condition using a fixed bed reactor. This study aimed at providing alternative processing of POME into biogas at the most optimum biogas yield without any pretreatment, taking advantage of POME conditions generated from the production process at the average temperature of 55 – 60 °C. In the anaerobic process, temperature conditions have a significant effect on bacteria's performance to degrade organic matter. In thermophilic conditions, bacteria deteriorate organic substrates more actively than in mesophilic states. This research proved that using fixed bed reactor technology to treat POME without pretreatment has generated biogas at the yield of 25.43 liters/liter of POME production. Applying this technology also demonstrated that investment and operating costs are cheaper due to having no mixing tank and fewer chemicals applications for the neutralization process. Keywords: biogas, fixed bed reactor, POME, pretreatment, thermophilic   ABSTRAK Proses pengolahan POME dapat dilakukan dengan menggunakan proses fermentasi anaerobik yaitu memanfaatkan kerja bakteri anaerobik untuk memproduksi biogas. Penelitian ini bertujuan memberikan alternatif pengelolaan limbah cair pabrik kelapa sawit yang dapat menghasilkan biogas yang paling optimal tanpa melakukan pretreatment. Proses yang dipilih disesuaikan dengan kondisi panas POME yang keluar proses yaitu sekitar 55 - 60 oC. Kondisi temperatur sangat berpengaruh nyata terhadap kinerja bakteri pendegradasi bahan organik di dalam limbah cair dalam proses anaerobik. Pada kondisi termofilik bakteri lebih aktif dibandingkan pada kondisi mesofilik. Melalui penelitian ini, dapat diketahui bahwa dengan menggunakan teknologi reaktor fixed bed untuk mengolah POME tanpa adanya pretreatment, biogas tetap dapat diperoleh dengan perolehan rata rata 25,43 liter per liter POME. Dengan menggunakan teknologi ini biaya investasi dan operasi akan lebih murah dikarenakan tidak memerlukan bak pencampur dan penggunaan bahan kimia untuk proses netralisasi.
