PENENTUAN KADAR ASAM LEMAK BEBAS PADA STORAGE TANK DAN KADAR AIR
PADAVCT,OIL TANK,FATFIT TANK DI PTP NUSANTARA III
SEI SILAU - ASAHAN
ABSTRAK
Telah dilakukan studi pengamatan lama waktu penimbunan CPO terhadap kadar asam lemak bebas pada storage tank dan kadar air pada vct tank,oil tank,fatfit tank di pabrik kelapa sawit PTPN III Sei Silau. Pengamatan dilakukan langsung di Laboratorium dengan menganalisis contoh minyak sawit mentah (CPO) pada tangki timbun dan mengambil beberapa parameter mutu sebagai objek untuk dianalisa yaitu kadar asam lemak bebaskadar asam lemak bebas pada storage tank dan kadar air pada vct tank,oil tank,fatfit tank. Kadar ALB diukur dengan menggunakan metode titrasi asam basa, sedangkan kadar air ditentukan dengan menggunakan metode gravimetri. Hasil analisa yang diperoleh untuk kadar ALB tertinggi sebesar 5,14%(pada hari ke-5). Untuk kadar air tertinggi pada vct tank 0,96% (pada hari ke-5) kadar air tertinggi pada oil tank 0,73% (pada hari ke-5). Untuk fat-fit tank tertinggi sebesar 0,61% (pada hari ke-5) Hal ini disebabkan oleh beberapa faktor yang mempengaruhi penurunan mutu minyak sawit yaitu kualitas buah yang diolah, sistem pencampuran produksi harian, serta temperatur tangki.

ABSTRACT
Observational studies have been done a long time accumulation of CPO against free fatty acid levels in the storage tanks and the water content in the VCT tanks, oil tanks, tank fatfit in palm oil mills PTPN III Sei glare. Observations were made directly in the laboratory to analyze samples of crude palm oil (CPO) in the storage tank and take some quality parameters as objects to be analyzed, namely fatty acid levels bebaskadar free fatty acids in the storage tank and the water content in the VCT tanks, oil tanks, fatfit tank. ALB levels were measured using acid-base titration method, while the water content was determined using gravimetric methods. The analysis results obtained for ALB highest levels by 5.14% (on day 5). For the highest water levels in tanks VCT 0.96% (on day 5) the highest water content in the oil tank 0.73% (on day 5). Fat-fit tank to a high of 0.61% (on day 5) It is caused by several factors influencing the decline in palm oil quality is the quality of the fruit is processed, mixing system daily production, as well as the temperature of the tank.
