| dc.description.abstract | Limbah Cair Kelapa Sawit (LCKS) memiliki kandungan bahan organik yang sangat tinggi dan berbahaya bagi lingkungan. Oleh karena itu, penelitian ini bertujuan menganalisis efisiensi pengolahan unit modifikasi RBC terhadap LCKSberdasarkan variasi laju pembebanan hidraulis (HLR) dan mengestimasi jumlah biomassa berdasarkan nilai parameter biokinetika terpilih. Penelitian diawali dengan tahap persiapan reaktor, aklimatisasi, konfigurasi reaktor, dan pengoperasian reaktor. Persen penyisihan terbaik dicapai saat pengoperasian reaktor dengan variasi HLR 0,15 m3/m2∙hari, yaitu sebesar 90% untuk parameter COD. Efisiensi pengolahan sangat dipengaruhi oleh ketersediaan biomasa di dalam
reaktor, sehingga estimasi nilai konsentrasi biomassa (Xa”) dapat dijadikan acuan dalam pembuatan model. Berdasarkan hasil permodelan yang dilakukan dapat diketahui nilai parameter biokinetika terpilih berupa µmax-a, µmax-s Ys, Ya, Ks-a, Ko, dan Ks-s secara berturut-turut sebesar 6; 5,54/hari; 2,21; 0,33 mgMLVSS/mgCOD; 262; 0,56; dan 30 mg/L. Parameter biokinetika dengan pengaruh terbesar terhadap estimasi nilai Xa”, yaitu Ys dan µmax-s yang menandakan peranan mikroorganisme tersuspensi di dalam unit modifikasi RBC. | id |
| dc.description.abstract | Palm Oil Mill Effluent (POME) contains a high concentration of organic matter that is hazardous to the environment. Therefore, this study aims to analyze the efficiency of the modified Rotating Biological Contactor (RBC) unit in treating POME based on variations in hydraulic loading rate (HLR) and estimate the biomass quantity based on selected biokinetic parameter values. The study began with reactor preparation, acclimatization, reactor configuration, and reactor operation stages. The highest removal percentage was achieved during reactor operation at HLR variation of 0.15 m3/m2·day, that reaching 90% for the COD parameter. The treatment efficiency is significantly influenced by the availability of biomass within the reactor, thus the estimated value of biomass concentration (Xa'') can serve as a reference in model development. Based on the modeling results, the selected biokinetic parameter values for µmax-a, µmax-s Ys, Ya, Ks-a,Ko, dan Ks-s, are 6; 5.54/day; 2.21; 0.33 mgMLVSS/mgCOD; 262; 0.56; and 30 mg/L. Among these parameters Ys and µmax-s have the greatest influence on estimating the value of Xa", indicating the role of suspended microorganisms in reactor. | id |
