dc.description.abstract | An investigation of the utilization of oil palm empty fruit bunch ash to reduce the content of oil/grease, BOD and COD from oil mill effluent.
Samples of palm oil mill effluent from wastewater treatment plant of PT Nusantara IV (Persero) oil processing unit sopsa of Padang Lawas district. Samples taken from the last pond will be discharged into the environment. Empty Fruit of Oil Palm Ash taken from the kitchen burning empty fruit bunches PT Nusantara IVB (Persero) units Sosa of Padang Lawas district. Ash Oil Palm Empty Fruit Bunches
From the research result shows that the value of initial oil content (before the addition Ash Oil Palm Empty Fruit Bunches) in samples of palm oil mill effluent of 37.5 mg/L. After the addition of Oil Palm Empty fruit Bunch Ash 3g with 15 minutes stirring time decreased to 23,1 mg/L.
Value of BOD content of early (before the addition Ash Oil Palm Empty Fruit Bunches) on Palm Oil Mill Waste of 256,45 mg/L.After the addition of oil palm empty fruit bunch ash 3g with 15 minutes stirring time decreased to 94,0 mg/L.
Value of COD content of early (before addition Ash Oil Palm Empty Fruit Bunches) on Palm Oil Mill Waste of 434,70 mg/L. After the addition of Oil Palm Empty Fruit Bunch Ash 3 g with 15 minutes stirring time decreased to 292.44 mg/L.
With the addition of heave Ash Oil Palm Empty Fruit Bunches 1g, 2g and 3g with stirring time 15 minutes result percentage decrease oil content/fat from a price 12,7%, percentage decrease reduction BOD a price 47,3% and the percentage reduction COD a price 11,4%. | en_US |
dc.description.abstract | Telah dilakukan penelitian tentang studi pemanfaatan abu tandan kosong kelapa sawit untuk menurunkan kandungan minyak/lemak, BOD dan COD dari limbah cair pabrik kelapa sawit.
Sampel limbah cair pabrik kelapa sawit berasal dari instalasi pengolahan air limbah PT Nusantara IV (persero) unit pengolahan sawit sosa kabupaten padang lawas. Sampel diambil dari kolam terakhir yang akan dibuang ke lingkungan. Abu Tandan Kosong kelapa sawit diambil dari dapur pembakaran tandan kosong PT Nusantara IV (Persero) unit sosa kabupaten padang lawas.
Dari hasil penelitian diketahui bahwa nilai kandungan minyak awal (sebelum penambahan Abu Tandan Kosong Kelapa Sawit) pada sampel limbah cair pabrik kelapa sawit sebesar 37,5 mg/L.Setelah penambahan Abu Tandan Kosong Kelapa Sawit 3g dengan waktu pengadukan 15 menit mengalami penurunan menjadi 23,1 g.
Nilai kandungan BOD awal (sebelum penambahan Abu Tandan Kosong Kosong Sawit) pada Limbah cair Pabrik Kelapa Sawit sebesar 256,45 mg/L. Setelah penambahan abu tandan kosong kelapa sawit 3 g dengan waktu pengadukan 15 menit mengalami penurunan menjadi 94,0 mg/L.
Nilai kandungan COD awal (sebelum penambahan Abu Tandan Kosong Kelapa Sawit) pada Limbah Cair Pabrik Kelapa Sawit sebesar 434,70 mg/L. Setelah penambahan Abu Tandan Kosong Kelapa Sawit 3g dengan waktu pengadukan 15 menit mengalami penurunan menjadi 292,44 mg/L.
Dengan penambahan berat Abu Tandan Kosong Kelapa Sawit 1 g, 2 g, dan 3 gdengan waktu pengadukan 5 menit, 10 menit dan 15 menit diperoleh hasil persentase penurunan kandungan minyak/lemak sebesar 12,7%, persentase penurunan BOD sebesar 47,3% dan persentase penurunan COD sebesar 11,4% | en_US |
