Abstract

Lemongrass (Cymbopogon citratus) is one of the plants which produce essential oil. Thequality of the essential oil can be determined from the physiochemical properties of the oil. In this study,chemical purification method is implemented by using bentonite as adsorbent. The Completely RandomDesign (CRD) factorial consisted of two factors is used in statistical data analysis. The first factor whichis observed is the time of adsorption (T) which is consisted of 4 levels which are T1 = 30 minutes, T2 = 60minutes, T3 = 90 minutes, and T4 = 120 minutes. The second factor is the absorbent concentration whichis consisted of 3 levels which are K1 = 1%, K2 = 5%, and K3 = 10%. The result of this study showed thatpurification using bentonite can improve the quality of the oil. Time of adsorption and adsorbentconcentration influenced the yield of lemongrass oil (P≥0,01). The physical properties of the oil producedwere in accordance with the Essential Oil Association of America standard. Adsorption processes notonly reduce the citral content of lemongrass oil, however, also reduce the content of non-oxygenatedterpenes which can damage the quality of the lemongrass oil.

Abstract

The aim of this research was to study biodiesel production from low cost feedstock of waste cooking oil (WCO) using hydrodynamic cavitation apparatus. A two-step processes esterification process and transesterification process using hydrodynamic cavitation for the production of biodiesel from WCO is presented. The first step is acid-catalyzed esterification process for reducing free fatty acid (FFA) content of WCO and followed by base-catalyzed transesterification process for converting WCO to biodiesel as the second step. The result of esterification process with methanol to oil molar ratio of 5 and temperature of 60 oC showed that the initial acid value of WCO of 3.9 mg KOH/g can be decreased to 1.81 mg KOH/g in 120 minutes. The highest yield of biodiesel in transesterification process of 89.4% obtained at reaction time of 150 minutes with methanol to oil molar ratio of 6. The biodiesel produced in the experiment was analyzed by gas chromatography-mass spectrometry (GC-MS), which showed that it mainly contained five fatty acid methyl esters. In addition, the properties of biodiesel showed that all of the fuel properties met the Indonesian National Standard (INS) No. 04-7182-2006 for biodiesel.

Abstract

The use of ultrasound in extraction process creates novel and interesting methodologies, which are often complementary to conventional extraction methods. In the present study, the use of ultrasound to extract oleoresin from ginger (Zingiber officinale R.) was investigated. The extraction was performed by using ethanol as solvent in the presence of ultrasonic irradiations operating at frequency of 42 kHz at extraction temperature of 60 o C. The oleoresin extracted was in the form of dark thick liquid with specific ginger flavor. Based on GC-MS analysis, the use of ultrasound was not give an effect on alteration of main component in ginger oleoresin. The main component in extracted ginger oleoresin was zingerone. Gingerol as one of the pungent principle of the ginger oleoresin was not detected due to decomposition of gingerol at a temperature above 45 o C. Extraction rate of ultrasound-assisted extraction was about 1.75 times more rapid than a conventional system based on soxhlet. The scanning electron microscopy images provided more evidence for the mechanical effects of ultrasound, mainly appearing on cells’ walls and shown by the destruction of cells, facilitating the release of their contents.

Abstract

Amla (Phyllanthus emblica) seeds have only been disposed of as waste and have not been utilized optimally. Utilizing the seeds to produce oil has been regarded as a promising approach for reducing solid wastes and producing value-added products. This study evaluated the effect of solid to solvent ratio and extraction time on yield, phytochemical content and physicochemical of oil extracted from amla seed using hexane as a solvent. The amla seed oil was extracted through the solid-liquid process at different solid to solvent ratios (1:20, 1:25 and 1:30 g/mL) and extraction times (30, 60, 90 and 120 minutes). The highest yield found was 10.97% at a solid to solvent ratio of 1:30 (g/mL) and an extraction time of 120 minutes. The highest concentrations of phenolic compounds and flavonoids were 66.12 mg GAE/g and 95.70 mg QE/g respectively, obtained at a solid to solvent ratio of 1:25 (g/mL) and extraction time of 120 minutes. Physicochemical analysis (pH, density, acid number, free fatty acid, and peroxide number) showed that the quality of extracted oil was better than what the previous study reported. In the amla seed oil, the content of unsaturated fatty acids was higher than saturated fatty acids with linoleate as the main component. These results clarified that solid-liquid extraction method can be used for extracting amla seed oil and also indicated that amla seed oil can be used as an ingredient in health-related industry products.

Abstract

The process of biodiesel purification is an important step in getting biodiesel products that meet specifications as a substitute for fossil-based fuels. Dry washing method has been developed to achieve an effective purication strategy in order to produce high-quality biodiesel. Bentonite can be used as dry washing agent because it has a good adsorbing properties as well as a large pore and surface area therefore can attract polar substances such as glycerol and methanol. The purpose of this research is to know the capability of activated bentonite as dry washing agent for purification of biodiesel produced from waste cooking oil. The activation process of bentonite was carried out using sulfuric acid with concentration 1.5 M. Characterization of the bentonite was conducted using X-Ray Diffraction (XRD) for minerals content and BrunauerEmmettTeller (BET) method for surface area. Bentonite was used as dry washing agent for biodiesel purification by varying washing time (10, 20, 30, 40 and 50 minutes) and adsorbent amount (1, 2, 3, 4 and 5%). The experimental results showed that purification of biodiesel by dry washing using activated bentonite resulted in a better yield and quality than wet washing and dry washing using non-activated bentonite, except the acid number. The best operation condition resulted from this research is at 10 minutes washing time and 1% adsorbent with yield of 94.1%; acid number of 0.4208 mg KOH/gram; density of 0.8838 gram/cm3, viscosity of 3.0617 mm2/s and water content of 1.17%.
