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.

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.

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. Kata kunci : kelapa sawit, POME, biohythane

Limbah cair kelapa sawit atau Palm Oil Mill Effluent (POME) merupakan bahan yang dapat digunakan untuk memproduksi biogas menggunakan reaktor anaerobik. Dalam limbah cair kelapa sawit terdapat beberapa komponen penyusun yaitu Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), dan Volatile Fatty Acid (VFA). Perubahan terhadap kandungan dalam limbah cair pabrik kelapa sawit (LCPKS) dipengaruhi oleh laju alir yang terjadi dalam bioreaktor anaerobik. Pada penelitian ini dilakukan variasi laju alir yaitu Q1 ambient 0 L/hari, Q2 6 L/hari, Q3 24 L/hari untuk mengetahui laju alir optimal dalam pengolahan LCPKS pada bioreaktor anaerobik. Pengamatan dilakukan secara rutin dan resirkulasi sampel POME dilakukan selama ± 6 jam/hari. Tujuan penelitian untuk mengetahui pengaruh laju alir terhadap perubahan kadar COD, BOD, dan VFA yang terkandung dalam LCPKS dengan menggunakan bioreaktor anaerobik. Hasil dari penelitian ini adalah laju alir optimal dalam penurunan kadar COD, BOD, dan VFA dalam LCPKS yaitu sebesar 24 L/menit, dimana semakin besar laju alir yang diberikan maka kadar penurunan COD dan BOD yang terkandung dalam limbah cair kelapa sawit akan semakin besar, hal tersebut juga berlaku pada pembentukan VFA pada limbah cair, hal ini disebabkan karena penambahan variasi laju alir dapat mempengaruhi proses degradasi bahan-bahan organik dalam limbah cair kelapa sawit. Kata Kunci : POME, laju alir, bioreaktor anaerobik, biogas, LCPKS.

Liquid waste from palm oil mill continues to grow concurrently with the increased production of palm oil in Indonesia. Technical processing of palm oil mill effluent using anaerobic ponds are less efficient because it requires large area besides palm oil mill effluent produce greenhouse gases caused by carbon dioxide gases that are generated. Therefore we need another alternative technology such as electrocoagulation as advanced technology in processing wastewater effluent from an anaerobic column. Electrocoagulation is a wastewater treatment system that is capable of eliminating pollutants and produce hydrogen gas simultaneously as revenue to offset operating costs. This study aims to determine the effect and the best inter electrode distance to reduce pollutant parameters such as chemical oxygen demand, total solids and total suspended solids. The type of electrode material used is aluminum, the reactor dimensions 12 cm x 12 cm x 36 cm with 3 hours of operating time, voltage 10 volts, variations of inter electrode distance 0.5 cm; 1.0 cm; 1.5 cm and 2.0 cm. Samples were taken from palm oil mill PT. PP London Sumatra in Bagerpang, Tanjung Morawa. The results obtained by the percentage reduction in COD, TSS TS and the highest was 72.897% at 1.0 cm; 67.292% at 1.5 cm and 96.429% at 1.5 cm. Best distance between the electrodes was 1.5 cm.
