Abstract

Cellulose was isolated from plantain skin and then carboxymethylated with trichloroacetic acid which resulted a 0.9936 gram of carboxymethylcellulose. The FT-IR spectroscopy analysis of carboxymethyltricellulose indicated the –OH vibration at wavelength of 3448.72 cm-1.Moreover, a wavenumber in the region of 1026.13 cm-1 is attributed to ether vibration (-O-) and carboxyl vibration at 1651.07 cm-1. The results of morphological analysis using SEM also showed a smoother, homogeneous pore, and a larger surface area. The adsorption capability for Cu2+ ions at concentration of 100 ppm was analyzed by atomic adsorption spectrophotometer (AAS). It shows that the optimum adsorption was found to be at a 90 minutes agitation process for both carboxymethyltricellulose and cellulose with about 97.266% and 21.602% respectively.

Abstract

Essential oil of Baru Cina leaves (Artemisia vulgaris L.) has been successfully isolated by hydrodistillation method using the Stahl apparatus. Baru Cina leaves were hydrodistillation for ± 6 hours to produce the essential oil amount of 0.39 % (v/b). The essential oil obtained from Baru Cina leaves was characterized by using GC-MS spectroscopy. The GC-MS analysis results showed that there were 29 compounds and the main compounds identified as many as 14 compounds, such as Alpha-Pinene (0.33%), 1,8-Cineol (1.96% ), Filifoline (1.41 %), 1-Octen-3-Ol (2.99 %), 2,4-Cycloheptadien-1-0ne (Eucarvone) (30.61 %), 2-Cyclohexen-1-Ol (Cis) (2.86 %), Bicyclo-3,3,1-Hepta-3-One (1.62 %), Trans-Caryophyllene (4.82 %), 3-Cyclohexen-1-Ol (1, 71 %), 2-Cyclohexen-1-Ol(Trans) (2.75 %), 2-Cyclohexen-1-One (Piperitone) (30.92 %), Trans Carveol (0.31%), Ar-Dimethylphenethyl Alcohol (0.88%), Eugenol (2.42%). This study also showed antioxidant activity from the essential oil of Baru Cina leaves with the IC50 value was 95.76 mg/L.

Abstract

The alkoxylation reaction was carried out between the fatty acid methyl ester epoxide of rubber seed oil (RSO) and cellulose to produce cellulose ether. RSO was obtained from rubber seed by extraction method with n-hexane solvent followed by a purification process including a degumming stage, bleaching and neutralization. The RSO obtained was further dimetanolized with a NaOH catalyst producing a fatty acid methyl ester which is then epoxidized with a performance acid to give the epoxide compound. The resulting epoxide compound was reacted with cellulose in an isopropanol solvent, producing ether cellulose. RSO obtained as much as 46.75% with a free fatty acid content of 0,2184%, iodine amount, and unsaturated fatty acid content of 82,4%. The resulting ether cellulose was found to be vibrations in the area waves number of (ῡ) = 1118 cm-1, which indicates the presence of C-O-C bonds from the ether, which can indicate that an etherification reaction has occurred in cellulose. This is also supported by the presence of vibrations at wave numbers (ῡ) = 1743 cm-1, (ῡ) = 1165 cm-1, (ῡ) = 1118 cm-1, (ῡ) = 725 cm-1, each of which shows the existence of a bond (C = O) from the ester, CH3 bond, C – O bond from the ester and bond to carbon (CH2) n where n ≥ 4, which is not found in cellulose but is found in cellulose ether. It shows that an alkoxylation epoxide reaction of MEAL rubber seed oil with cellulose has occurred, which will produce cellulose ether.

Abstract

Methyl cellulose is synthesized by an etherification reaction between α-cellulose created by isolating rice husks (Oryza sativa L.) with methylene chloride. Methylcellulose synthesis is performed by combining 1 g α-cellulose with acetone solvents at variations of methylene chloride 6 g, 8 g, 10 g, 12 g, and 14 g for 6 hours, resulting in 0.47 g, 0.60 g, 0.58 g; 0.51 g; and 0.69 g of methylcellulose. The results of methyl cellulose synthesis were tested with Degrees of  Substitution, FT-IR spectroscopic analysis, and surface morphology using SEM. In the variation of methylene chloride, methylcellulose has the highest degree of replacement (14 g of 01,17). The formation of methyl cellulose is supported by FT-IR spectroscopy, namely with the appearance of vibration peaks in the wave number area of 3295.0 cm-1, which shows the -OH group, the C-H stretching group at wave number 2892.4 cm-1, the absorption peak that indicates the presence of C-O-C is found in wave numbers 1152.6 cm-1 and 1021.3 cm-1 where it is an asymmetrical and symmetrical stretching vibration. Morphological analysis using SEM showed that cellulose fibers' surface is smoother than methylcellulose. The average size of cellulose and methyl cellulose fibers is 4.791 μm and 3.828 μm, respectively. Morphological analysis using SEM showed that the surface fibers in cellulose were smoother than methylcellulose. The average size of cellulose and methyl cellulose fibers was 4.791 μm and 3.828 μm.
