Abstract

In the fractional distillation process, the pressure that used is one of the important factors determining the operating conditions to obtain optimal product. This research aims to determine the effect of pressure on the fractinal distillation process of patchouli oil. The research method that used in this research was an experimental method with descriptive analysis. This research was conducted with three treatments that is different pressure treatments and repeated twice. The pressure treatments that used in the fractional distillation process are A = 5 mmHg, B = 10 mmHg, and C = 15 mmHg and arranged to produce five (5) fractions of each treatment. The parameters that measured including the yield of fractional distillation, distillation process time, specific gravity, and refractive index. The lower the pressure used in the distillation process, the greater the yield and the faster the distillation process time. The results of this research indicate that the variation of pressure that used does not have a significant effect on the characteristics of patchouli oil such as specific gravity and refractive index. The application of 5 mmHg pressure is good enough to separate the distillate yield into 5 fractions and is more efficient because it obtains the highest total yield of 93.5% with a distillation process time of 18.16 hours.

Abstract

Effects of both near critical and supercritical CO2 pasteurization on inactivation of muscle protease and lipase of red tilapia (Oreochromis niloticus) were investigated along with its impact on microbial reduction and physical appearance. Near critical phase was designed at 70 bar and supercritical phases were designed at 80 and 90 bar.  It was found that CO2 pressure had greater effect on protease inactivation  than on lipase inactivation. Temperature increase did not improve both protease and lipase inactivation while fillet texture was adversely affected. The fillet color experienced color changes significantly.

Abstract

Biomassa originated from palm oil plant is potential to be processed into various industrial products. In the production line this material needs to dry into certain level of moisture content, mostly about 10% (wet basis) and commonly called as dry material. It is advantageous if the dryng time to produce a dry material can be predicted. Prediction is usually approached by setting up drying model of the material. The most common drying model in formulated in the form of moisture ratio in function of drying time in which the moisture content is calculated in dry basis. On the other, in practice, the moisture content of material is expressed in wet basis. The objectives of this research were to determine the drying curves and to predict the drying times of palm oil empty fruit bunches, stem and fiber dried from solar dying and oven drying. Three series of experiments were carried out according to the types of materials. The results of the experiments revealed as follows. The curves produced by the solar energy dryer operating at drying temperatures ranged from 42oC to 54,5oC for both empty fruit bunches and stem were quadratic whereas the curves produced by the oven having temperature of 105 oC for stem and fiber were linear and quadratic respectively. The form of curves obtained from the relationships between materials moisture contents determined in wet basis and drying times were similar to the curves of materials moisture ratios in function of drying times. The drying times of the solar energy drying for the empty fruit bunches were 20 hours dan 19.3 hours for Dura variety and Tenera variety respectively while those of stems were 16.3 hours and 17.9 hours respectively for Dura variety and Tenera variety. The drying times of the oven drying for the stems were 7.1 hours, 6.9 hours and 5.0 hours respectively for the lower, middle and upper parts of the stems. The drying times of oven drying for the fibers were 6.4 hours and  6.2 hours respectively for the outer and inner field stacks empty fruit bunches origins
