Abstract

Optimization of extraction parameter of oleoresin from nutmeg waste has been developed.The waste could be alternative raw material of oleoresin to replace fresh nutmeg whose price is costly. Sofar, nutmeg waste from volatile oil factory is not utilized maximally. Its utilization as product that hasadditional value could be carried out by extraction method of nutmeg oleoresin. The research aims tooptimize oleoresin extraction condition (temperature, solvent amount, and particle size) from nutmegwaste by using Response Surface Methodology. The condition is designed randomly by Box-Behnkenmethod to result in 17 experiment. The effect of extraction condition toward yield and index of refractionis determined through calculation and analysis by using refractometer, respectively. The highest value ofindex of refraction in the research is 1.4852. The optimum condition to result in the highest yield14.5525% is at temperature of 40oC, solvent amount of 200 ml, and particle size of -20+30 mesh.Optimization by using the method indicates that optimum parameter is obtained at temperature of35.86oC, solvent amount of 167.13 ml, and particle size of 10 mesh. The research result is expected toprovide information on operational effectivity in the perspective of production cost that could be utilizedby production center of nutmeg oleoresin.
PRODUKSI BIODIESEL DARI MINYAK BIJI JARAK (Jatropha curcas) DENGAN MENGGUNAKAN KATALIS KALIUM HIDROKSIDA (KOH) Production of Biodiesel from Jatropha Seed (Jatropha Curcas) Oil Using KOH as Catalyst Kasturi, Kasturi; Riza, Medyan; Supardan, Muhamad Dani

Abstract

Nowadays, the use of fuel as the primer source of energy has been carriedout using petroleum classified as non-renewable fossil. The product needed hassignificantly increased along with its uses in industry and transportation lastly spurringthe necessity of a new alternative source of energy. This research was aimed to obtain bestoperating condition to product biodiesel via transesterification process of jatropha seedusing 3% wt. of KOH as catalyst. Condition process of producing biodiesel were at 30, 40,50, 60 and 70C of process temperatures, 200, 300 and 400 rpm of agitation speeds, and1:12, 1:14, and 1:16 of mole ratios between jatropha seed and methanol. The result of thisresearch showed that the higher ratio between Jatropha curcas and methanol the higherbiodiesel obtained. While for the operating condition, the faster agitation speed alsoinfluenced in the more amount of biodiesel yield. Best operating temperature obtained wasat 60C. The analysis of the product including density, viscosity, acid number and flashpoint were 846 kg/m3, 5 cSt, 0,67 mg KOH/gr and 35C, respectively.
