Produksi minyak mentah kelapa sawit yang mengalami peningkatan setiap tahunnya mengakibatkanmeningkatnya pula produksi limbah cair kelapa sawit atau palm oil mill effluent (POME). POMEmemiliki kandungan organik yang tinggi sehingga tidak dapat dibuang secara langsung ke lingkungan.Di sisi lain, tingginya nilai COD dalam POME ini sebenarnya dapat memberikan potensi untuk konversilistrik dengan menangkap gas metana atau biogas yang dihasilkan melalui serangkaian tahapanproses peruraian POME. Dalam kajian ini dilakukan pendataan potensi POME dari Pabrik KelapaSawit (PKS) Sei Pagar serta perencanaan proses produksi biogas dari POME. Data yang didapatseperti nilai COD, BOD, TSS, dan debit digunakan sebagai basic engineering design produksi biogasdari POME. Dalam perencanaan proses dipilih reaktor CSTR untuk proses produksi biogas. Selain itu,dilakukan proses pre-treatment terlebih dahulu untuk menyesuaikan POME dengan kondisi optimumreaktor. Biogas yang dihasilkan akan dipurifikasi sebelum masuk ke gas engine dan diubah menjadienergi listrik. Dengan kapasitas limbah POME di PKS Sei Pagar yakni sebesar 15 m3/jam dan waktu3pengumpanan 16 jam diharapkan mampu menghasilkan 119 m /jam biogas yang kemudian dapatdikonversi menjadi energi listrik sebesar 532 kW.Kata kunci: POME, biogas, COD, CSTR, desain basis

Pre Treatment

The global pandemic spread of influenza like bird flu and swine flu are forcing abigger production of anti-influenza drug called Oseltamivir phosphate. The drug is made by synthesizing a compound named shikimic acid. Although the demand of the drug increases, the source of shikimic acid material is limited. Meanwhile, palm oil mill effluent (POME), a waste generated from palm oil industry is provenly rich in phytonutrients. This research aims to improve the shikimic extraction process from palm oil mill effluent by pre-treating the POME. Three pre-treatments were done on the POME which are solvent-extraction method, sedimentation method, and combination of solvent-extraction and sedimentation method. Sedimentation used the centrifugal principle and solvent-extraction used n-hexane as the solvent. Extraction of shikimic acid from pre-treated POME was done using ethyl acetate as the solvent. Detection of shikimic acid was done using TLC method and FT-IR instrument, while HPLC was used to measure the amount of shikimic acid extracted. Yield of shikimic acid obtained after solvent-extraction pre-treatment (0.0795%) was better than the sedimentation pre-treatment (0.015%). Also, the solvent-extraction pre-treatment was more efficient (87.51%) than sedimentation pre-treatment (68.15%) in removing oil and grease. However, the best result was produced from the combination of both pre-treatments.

Microalgae Growth

Palm oil mill effluent (POME) is the wastewater produced during the palm oil sterilization process, which contains substantial amounts of nutrients and phosphorous that are harmful to the environment. High BOD and COD of POME are as high as 100,000 mg/L, which endanger the environment. Effective pre-treatment of POME is required before disposal. As microalgae have the ability of biosorption on nutrients and phosphorous to perform photosynthesis, they can be utilized as a sustainable POME treatment operation, which contributes to effective biofuel production. Microalgae species C. pyrenoidosa has shown to achieve 68% lipid production along with 71% nutrient reduction in POME. In this study, a brief discussion about the impacts of POME that will affect the environment is presented. Additionally, the potential of microalgae in treating POME is evaluated along with its benefits. Furthermore, the condition of microalgae growth in the POME is also assessed to study the suitable condition for microalgae to be cultivated in. Moreover, experimental studies on characteristics and performance of microalgae are being evaluated for their feasibility. One of the profitable applications of POME treatment using microalgae is biofuel production, which will be discussed in this review. However, with the advantages brought from cultivating microalgae in POME, there are also some concerns, as microalgae will cause pollution if they are not handled well, as discussed in the last section of this paper.

Palm Oil Mill

Pabrik kelapa sawit menghasilkan 0,7 – 1 m3 limbah cair kelapa sawit atau palm oil mill effluent (POME) setiap ton TBS. Untuk pabrik sawit dengan kapasitas 30 ton tandan buah segar per jam, akan dihasilkan 6 ton minyak sawit, 6 ton limbah fiber, 10 ton cangkang dan limbah cair yang dapat menghasilkan listrik 1MW. Proses fermentasi limbah POME ini akan menghasilkan biogas dengan kandungan utama metana (CH4) sebesar 62%. Biogas adalah campuran gas yang diproduksi oleh sekelompok mikroorganisme dengan menguraikan material biodegradable pada kondisi anaerobik. Biogas sebagian besar terdiri atas 50% sampai dengan 70% metana (CH4), 30% sampai 45% karbon dioksida (CO2) dan sedikit kandungan gas lainnya seperti H2S, H2, N2, dan uap air. Untuk dapat memanfaatkan biogas hasil metanisasi dari POME untuk dikonversi menjadi listrik, maka biogas harus terlebih dahulu dilakukan permunian untuk menyesuaikan spesifikasi biogas sebagai bahan bakar gas dengan persyaratan mesin gas yang digunakan. Komponen-komponen di dalam biogas yang perlu dihilangkan ataupun dikurangi meliputi kandungan air, padatan, dan senyawa sulphur. Pada penelitian ini dilakukan pengembangan sistem proses pemurnian biogas dengan menggunakan Bioscrubber untuk mengurangi kandungan gas H2S dan Dehumidifier untuk mengurangi kandungan uap air dalam produk biogas sehingga dihasilkan biogas dengan spesifikasi yang sesuai dengan umpan Gas Engine.
