Abstract

The production of bioetanol by using acid hydrolisis method resulted the formation of compounds which can destructed the fermentation process, such as HMF or furfural, thus it needs detoxification process to erase or decrease it. Detoxification process is done by adding alkali in to hidrolisat before it is used as fermentation substrat. Alkali compound which is usually used are Ca(OH)2 or NH4OH. This research is conducted to compare ethanol rendement resulted from the detoxification process, and also to decide the most optimal detoxification that can be done to produce the best etanol rendement. The study is done by using distinct treatmentof catalist, that are Ca(OH)2 dan NH4OH as well as the stirring/mixing time, which are control, 15, 30 and 45 minutes during detoxification process. Based on the result of the study, it can be concluded that etanol rendement resulted from hydrolisat which is detoxificated by using catalyst NH4OH is higher than the one which use catalyst Ca(OH)2. Acid hydrolisat detoxification method from cassava in order to produce an optimal bioetanol is by using catalist NH4OH with free stirring time(less than 15 minutes)

Abstract

The methods for quantitative determination of cholesterol in foods by chromatography determination Two types of lipid classes including free cholesterol and cholesterol ester exist in food. Total cholesterol is measured after chemical hydrolysis of cholesterol esters to free cholesterolPrior to instrumental analysis, cholesterol is extracted from the food sample and saponified. The amount of the food sample depends on the cholesterol content; a sample containing ∼1 mg of cholesterol is required for lipid extraction. Saponification hydrolyzes the carboxyl group attached to carbon in cholesterol and yields only free cholesterol in unsaponifiable matter. The unsaponifiable matter can be extracted by n-hexane, diethyl ether, or petroleum ether. In the present protocol, unsaponifiable matter is extracted using n-hexane. This protocol requires prior knowledge of GC  methodologies and adherence to instructions from the instrument’s manufacturer.

Abstract

Surfactant injection is one of the ways to lessen oil remains left in reservoir. This is done by injecting an active surface substance into reservoir until the tension of water-oil interface can be degraded. Reducing interfacial tension results in a reduced capillary pressure on pore stricture area of reservoir rocks until the oil caught in the pores can be pushed and produced.  In order to make this process function optimally, an appropriate surfactant that fits the condition and formation of water and reservoir is needed.  This study was conducted to get the best time of sulfonation process for producing MES surfactant with lower interfacial tension for EOR application at carbonate rock and to determine purification process of MES surfactant. Results showed that the best time of sulphonation to produce MES surfactant was from the third hour to the fourth hour.  The selected purification process was conducted without methanol addition.

Abstract

Biodiesel, a renewable fuel is normally produced from refine oil and methanol in the presence of a catalyst; conventionally it is used a basic homogeneous catalyst. However, when oil with high amount of free fatty acid (FFA) is used, this catalyst should not be used with the aim to avoid the production soap. In this work, FFA present in crude palm oil (CPO) were esterified with activated natural zeolite catalyst. The esterification reaction was carried out 60oC, with a  23.41 : 1 molar ratio of methanol to CPO, reaction time of 170 minute and catalyst amount of 1.59 %, conversion FFA of CPO was 64.23 %. In this work, biodiesel yield achieved was around 71.97 %.Biodiesel, a renewable fuel is normally produced from refine oil and methanol in the presence of a catalyst; conventionally it is used a basic homogeneous catalyst.

Abstract

Fruits can suddenly loose its quality, thus it needs a good packaging material with a suitable permebiality, so that gas exchange inside the packaging normally take place through film packaging. The increasing of permeability on plastic film can be done by giving perforation or a whole on its surface. This research is intended to find out the rate gas exchange through film packaging. In packaging system with modified atmosphire. The result of this research shows that the use of perforation with micro size (50-200 µm) can increase the rate of gas transmission of plastic film toward O. Identification on packaging material which is used reveal that plastic permeability without perforation toward O2 is less than plastic permeability with 10 perforation. Gas equilibrium for 10 perforation packaging resulted on day 21 with gas concentration 0,001% (O2) and 0,000798 % (CO2). The approach by using mathemathic model is done to find out gas concentration inside the packaging during the storage. The model which is developed by Gonzales et al. (2008) nearly close to the result as the observation conducted.
