Performance of anaerobic hybrid bunch-frond palm mediated bioreactor in COD elimination The high contents of Chemical Oxygen Demand (COD) in palm oil mill wastewater is able to cause the obstructed connection between air and a receiver of water body so that can make the lessening oxygen solubility in the receiver of water body. Hence, it is important to do innovation to get a good technology process of wastewater in order that the contents of COD become low. One of the wastewater processes can be done by using hybrid anaerobic bioreactor in eliminating COD that exists in palm oil mill wastewater. This research uses two units of hybrid anaerobic bioreactor i.e. hybrid anaerobic bioreactor mediated immobilization cell of empty stem palm and hybrid anaerobic bioreactor mediated immobilization cell of in 2.5 m3 of work volume. The process is done by using variation of imposition organic rate i.e. 10, 12.5, 14.28, 16.6, 20, 25, 33.3, and 50 kg COD/m3-day. The result of research showed that the highest eliminating COD is 82.67% in 14.28 kg COD/m3-day in bioreactor filled with empty palm fruit bunch and 84% for imposition organic rate 16.6 kg COD/m3-day in bioreactor filled with palm midrib. Therefore, both hybrid anaerobic bioreactors can be used for processing oil palm mill wastewater in high load of COD. Keywords: hybrid bioreactor, COD, wastewater, palm midrib, empty stem palmAbstrakKandungan Chemical Oxygen Demand (COD) yang tinggi dalam limbah cair pabrik minyak sawit dapat menyebabkan terhambatnya kontak antara udara dengan badan air penerima sehingga mengakibatkan berkurangnya kelarutan oksigen dalam badan air penerima tersebut. Oleh karena itu, penting dilakukan terobosan baru untuk mendapatkan teknologi pengolahan limbah cair yang handal agar kandungan COD menjadi rendah. Salah satu teknologi pengolahan limbah cair tersebut adalah bioreaktor hibrid anaerob. Penelitian ini bertujuan mengkaji kinerja beberapa jenis bioreaktor hibrid anaerob dalam penyisihan COD dalam limbah cair pabrik minyak sawit. Pada penelitian ini digunakan dua unit bioreaktor yakni bioreaktor hibrid anaerob dengan media imobilisasi sel tandan kosong sawit dan bioreaktor hibrid anaerob dengan media imobilisasi sel pelepah sawit dengan volume kerja 2,5 m3. Proses pengolahan dilakukan dengan variasi laju pembebanan zat organik, yaitu10; 12,5; 14,28; 16,6; 20; 25; 33,3; 50 kg COD/m3hari. Hasil penelitian menunjukkan bahwa penyisihan COD yang tertinggi dicapai sebesar 82,67% dengan laju pembebanan organik 14,28 kg COD/m3hari pada bioreaktor bermedia tandan kosong sawit dan 84% untuk laju pembebanan organik 16,6 kg COD/ m3hari pada bioreaktor bermedia pelepah sawit. Dengan demikian, kedua bioreaktor hibrid anaerob ini dapat digunakan untuk mengolah limbah cair industri minyak sawit dengan beban COD tinggi.Kata kunci: bioreaktor hibrid, COD, limbah cair, pelepah sawit, tandan kosong sawit

This study was designed to investigate the fungi associated with palm oil mill effluent (POME) in Gulur village of Tumkur. Biodegradation of palm oil mill effluents was conducted to measure the discarded POME based on physicochemical quality. The fungi that were isolated are Aspergillusniger, A. flavus, A. fumigatus, A. ochraceus, Rhizopussp, Peniciliumsp and Trichodermavirde. The autoclaved and unautoclaved raw POME samples were incubated for 7 days and the activities of the fungi were observed each for 12 hours. The supernatants of the digested POME were investigated for the removal of chemical oxygen demand (COD), color (ADMI), and biochemical oxygen demand (BOD) at the end of each digestion cycle. The results showed that the unautoclaved raw POME sample degraded better than the inoculated POME sample and this suggests that the microorganisms that are indigenous in the POME are more effective than the introduced micro-organisms. This result, however, indicates the prospect of isolating indigenous microorganisms in the POME for effective biodegradation of POME. Moreover, the effective treatment of POME yields useful products such as reduction of BOD, COD, and color.

Palm Oil Mill Effluent (POME) merupakan limbah minyak kelapa sawit yang memiliki kadar Chemical Oxygen Demand (COD) dan Biochemical Oxygen Demand (BOD) yang tinggi dan sehingga merusak ekosistem periairan serta menurunkan kadar oksigen terlarut (DO). Namun, POME memiliki nutrisi untuk sel alga dalam memproduksi oksigen. Berdasarkan hal tersebut diperlukan identifikasi POME yang jatuh kebadan air berdasarkan fotosintesis Chlorella sp. menggunakan biosensor. Biosensor telah banyak dikembangkan dalam aplikasi bidang lingkungan dengan melihat kadar oksigen terlarut sebagai kualitas perairan. Penelitian ini menggunakan biosensor dengan prinsip sensor amperometris  tipe Biochip-G. Sensor amperometris mengukur perubahan arus dari reaksi reduksi dan oksidasi dan menghasilkan potensial keluaran yang terukur. Potensial keluaran yang terukur merupakan kadar oksigen terlarut dari penambahan POME terhadap Chlorella sp. ketika proses fotosintesis terjadi. Identifikasi POME berdasarkan proses fotosintesis Chlorella sp. menggunakan cahaya artifisial LED Putih 380 nm-780 nm dengan tingkat variasi konsentrasi POME sebanyak 10%, 20%, dan 30%. Berdasarkan pengukuran kadar oksigen terlarut (DO) menghasilkan nilai DO sebesar 174.15%, 154.66%, dan 138.98% serta nilai sensitivitas sebesar 4mV/%POME.

ABSTRAKEnergi  memiliki  peranan penting dalam proses pembangunan yang pada akhirnya untuk mencapai tujuan sosial,  ekonomi  dan  lingkungan  untuk  serta  merupakan  pendukung bagi kegiatan  ekonomi  nasional. Sumber energi terbarukan yang berasal dari pemanfaatan biogas limbah cair kelapa sawit dapat menghasilkan energi listrik yang saat ini banyak bergantung pada generator diesel dengan biaya yang mahal.Limbah cair kelapa sawit (Palm Oil Mill Effluent atau POME) adalah limbah cair yang berminyak dan tidak beracun, berasal dari proses pengolahan minyak kelapa sawit, namun limbah cair tersebut dapat menyebabkan bencana lingkungan apabila tidak dimanfaatkan dan dibuang di kolam terbuka karena akan melepaskan sejumlah besar gas metana dan gas berbahaya lainnya ke udara yang menyebabkan terjadinya emisi gas rumah kaca. Tingginya kandungan Chemical Oxygen Demand (COD) sebesar 50.000-70.000 mg/l dalam limbah cair kelapa sawit memberikan potensi untuk dapat di konversi menjadi listrik dengan menangkap biogas (gas metana) yang dihasilkan melalui serangkaian tahapan proses pemurnian. Di Kabupaten Kotawaringin Timur terdapat 36 Pabrik Pengolahan Kelapa Sawit yang total kapasitas pabriknya adalah sebesar 2.115 TBS/jam, menghasilkan limbah cair sebesar 1.269 ton limbah cari/jam dan mampu menghasilkan 42.300 m3 biogas.Kata kunci:  Renewable Energy, Plam Oil Mill Effluent, Chemical Oxygen Demand, Biogass, Methane. ABSTRACTEnergy has an important role in the development process and ultimately to achieve the objectives of social, economic and environment for as well as an environmental support for national economic activity. Renewable energy source derived from wastewater biogas utilization of oil palm can produce electrical energy which is currently heavily dependent on diesel generators at a cost that mahal.Limbah liquid palm oil (Palm Oil Mill Effluent, or POME) is the wastewater that is greasy and non-toxic, derived from the processing of palm oil, but the liquid waste could cause environmental disaster if not used and disposed of in open ponds because it will release large amounts of methane and other harmful gases into the air that cause greenhouse gas emissions. The high content of Chemical Oxygen Demand (COD) of 50000-70000 mg / l in the liquid waste palm oil provides the potential to be converted into electricity by capturing the biogas (methane gas) produced through a series of stages of the purification process. In East Kotawaringin there are 36 palm oil processing factory that total factory capacity is of 2,115 TBS / hour, producing 1,269 tons of liquid waste wastewater / h and is capable of producing 42,300 m3 of biogas.Keywords:  Renewable Energy, Plam Oil Mill Effluent, Chemical Oxygen Demand, Biogass, MethaneCara sitasi: Alkusma, Y.M., Hermawan, dan Hadiyanto.

Perkembangan energi terbarukan berbasis biomassa semakin dibutuhkan mengingat melimpahnya komoditas biomassa di Indonesia khususnya kelapa sawit serta makin menurunnya cadangan sumberdaya berbasis fosil. Komoditas sawit menjadi salah satu produk perkebunan utama nasional dan menjadi produksi terbesar didunia hingga saat ini yang dimanfaatkan sebagian besar untuk kebutuhan pangan serta sejumlah kecil energi (Biodiesel). Proses ekstraksi T andan Buah Segar (TBS) kelapa sawit tersebut menghasilkan Palm Oil Mill Effluent (POME) dengan Chemical Oxygen Demand(COD) yang tinggi (35.000 ppm). Melalui fermentasi POME dua tahap dalam prototipe sistem 3biohytane berkapasitas 1 m berpotensi menghasilkan listrik dari biohidrogen dan biometana sebesar 5,691 kWe. Ditinjau dari sisi keekonomian, dengan investasi (CAPEX) sebesar US$ 27.559 dan biaya operasional (OPEX) sebesar US$ 1 1.263/tahun akan diperoleh Biaya Pokok Produksi (BPP) sebesar US$ 0,323/kWh, Power Purchase Agreement (PP A) sebesar US$ 0,503/kWh dan tarif penjualan listrik US$ 0,508/kWh. Perbandingan BPP dengan jenis pembangkit lain menunjukkan bahwa BPP yang dihasilkan dari prototipe sistem biohythane cukup kompetitif untuk mensubsitusi pemakaian minyak solar pada PL TD yang saat ini memiliki nilai BPP lebih tinggi.
