Abstract

Palm Oil Mill Effluent (POME) is a by-product of the Crude Palm Oil (CPO) production process in the palm oil industry. POME has a high content of Chemical Oxygen Demand (COD), as well as oil and grease, and can disrupt aquatic biota ecosystems, so POME cannot be discharged directly into water bodies. This study combined the pre-treatment of coagulation and anaerobic digestion to obtain maximum methane. This study aims to study the effect of coagulant (alum) doses on changes in the characteristics of POME waste, study the effect of pre-coagulation treatment on the anaerobic digestion process in POME waste, and suppress cumulative methane production with the modified Gompertz model. The method used was coagulation using a 1 L beaker glass at room temperature with a stirring speed of 200 rpm for 2 hours and the precipitation process for 24 hours. The anaerobic digestion process was carried out using a digester with a volume of 500 mL in batch conditions at room temperature until the volume of biogas production was constant. The results of the study showed that the initial coagulation treatment with a coagulant dose of 6 g/L was able to reduce COD and TS levels to reach the optimal range of anaerobic digestion with COD values of 12,775 mg/L and TS 15,000 mg/L (15% w/v). This condition resulted in the highest biogas volume of 179.31 mL/g COD. In addition, the dose of 6 g/L also produced the highest cumulative prediction of methane using the Gompertz model, with kinetic parameters  (2.89 days), A (185.23 mL/g COD), and  (34.37 mL/g COD day).

Additional Information:	Palm Oil Mill Effluent (POME) merupakan limbah cair hasil samping proses produksi Crude Palm Oil (CPO) pada industri kelapa sawit. POME memiliki kandungan Chemical Oxygen Demand (COD), serta minyak dan lemak yang tinggi dan dapat mengganggu ekosistem biota air, sehingga POME tidak dapat dibuang langsung ke badan air. Penelitian ini mengombinasikan perlakuan awal koagulasi dan pencernaan anaerob untuk mendapatkan metana yang maksimal. Penelitian ini bertujuan untuk mempelajari pengaruh dosis koagulan (alum) terhadap perubahan karakteristik limbah POME, mempelajari pengaruh perlakuan awal koagulasi terhadap proses pencernaan anaerob pada limbah POME, dan menekan produksi metana kumulatif dengan model modifikasi Gompertz. Metode yang dilakukan, yaitu koagulasi dengan menggunakan beaker glass bervolume 1 L pada suhu kamar dengan kecepatan pengadukan 200 rpm selama 2 jam dan proses pengdapan selama 24 jam. Proses pencernaan anaerob dilakukan menggunakan digester bervolume 500 mL kondisi batch pada suhu kamar hingga volume produksi biogas konstan. Hasil dari penelitian menunjukkan, perlakuan awal koagulasi dengan dosis koagulan 6 g/L mampu menurunkan kadar COD dan TS mencapai rentang optimal pencernaan anaerob dengan nilai COD 12.775 mg/L dan TS 15.000 mg/L (15% w/v). Kondisi ini menghasilkan volume biogas tertinggi sebesar 179,31 mL/g COD. Selain itu, dosis 6 g/L juga menghasilkan prediksi kumulatif metana tertinggi menggunakan model Gompertz, dengan parameter kinetik  (2,89 hari), A (185,23 mL/g COD), dan  (34,37 mL/g COD hari).
