PENGARUH JUMLAH AIR PENGENCER DALAM PROSES
PENGEPRESAN (SCREW PRESS) TERHADAP
PRESENTASI KEHILANGAN MINYAK KELAPA SAWIT PADA
AMPAS PRESS
PT.SOCFIN INDONESIA KEBUN AEK LOBA
ABSTRAK
Dalam proses pengolahan minyak kelapa sawit pada Pabrik Kelapa Sawit PT. Socfindo Kebun Aek Loba. Proses yang paling penting pada stasiun pengepresan dalam proses pengempaan, dimana air panas yang ditambahkan ke dalam screw press bertujuan untuk pengenceran bubur (dillution) sehingga massa bubur yang dikempa tidak terlalu rapat. Penambahan air dalam proses pengepressan (screw press) akan berpengaruh besar terhadap presentase kehilangan dari minyak kelapa sawit, maka dari itu dilakukan penelitian mengenai optimalisasi dan pengaruh penambahan air untuk pengenceran pada proses pengepresan sawit. Dari hasil penelitian dengan variasi volume air 40, 50, 60, 70, dan 80 ml air, diperoleh presentase kehilangan minyak sebanyak : 8,03%; 7,67%; 5,09%; 5,07%; 4,98% . Dari penambahan sebanyak 60 ml air diperoleh persentase kehilangan minyak 5,09% yang telah sesuai dengan standar mutu yaitu di bawah 7,50%.

EFFECT OF TOTAL DILUTION WATER PRESSING PROCESS
(SCREW PRESS) PERCENTAGE OF LOSS IN
PALM OIL PRESS AMPAS
PT. SOCFIN INDONESIA AEK LOBA ESTATE
ABSTRACT
In the processing of palm oil in the palm oil mill PT. Socfindo Aek Loba Estate. The most important process at the pressing station in the compression process, where hot water that are added into the screw press is aimed at diluting the slurry (dillution) so that the mass of slurry is not too tightly falted. The addition of water in the pressing process (screw press) will greatly affect the percentage loss of crude palm oil, and therefore do research on optimization and the addition of water for dilution effect of the oil pressing process. And research results with a variation of the volume of water 40, 50, 60, 70, and 80 ml of water. Oil gained as much as the persentage loss : 8.30; 7.67; 5.09; 5.07; 4.98% from the addition of 60 ml of water obtained 5.09% percentage loss of oil that complies with the standards of quality that is below 7.50%.
