PENGARUH SUHU PEMANASAN AWAL DAN TEKANAN TERHADAP PEROLEHAN MINYAK BIJI NYAMPLUNG (COLLAPHYLUM INOPHYLLUM) DENGAN MENGGUNAKAN METODE PENGEPRESAN (Effect Of Preheating Temperature and Pressure on Nyamplung (Collaphyllum Inophyllum) seed’s oil using press hidraulic)

Abstract

One of plants that have the potential to be used as alternative fuel producers is nyamplung plant (Callophylum inophylum). The nyamplung plant’s seeds have the potential to produce nyamplung’s oil, especially the old’s seeds. Oil content in the seeds of nyamplung plant reach 40-70%. Extraction proccess of nyamplung seed’s oil using a hydraulic press with pre-treatment consists of the sorting process and heating proccess with variable of preheating temperature are 60o C, 80o C, 100o C and the variable of pressure are 80 kg / cm2, 100 kg / cm2, 140 kg / cm2. Based on observations in 9 variables obtained the highest oil yield percentage is on variable 9 by 48.4% (on a heating temperature of 100C with a pressure of 140 kg / cm2) with a content of 1.82% moisture content, density obtained for 0.954 gr / ml, viscosity obtained by the 27.664 Cp, And has a sour figure of 69.68 mgKOH / g and a saponification number of 189.940 mgKOH/g.
