Abstract

This study aims to determine the standardization of ethyl acetate extract of frankincense gum using the maceration method. The method used in this study was to standardize the ethyl acetate extract of frankincense using specific and non-specific parameters. The results of standardization with specific parameters showed that the ethyl acetate extract of frankincense latex was blackish brown in color and had a distinctive odor of frankincense. It contained 86.5% soluble compound in ethanol. The results of standardization with non-specific parameters showed a specific gravity of 0.8213 g/ml and an average moisture content of 1.71%. The chemical components contained are Benzoic acid; Vanillin; transCinnamic acid; Phenol, 2-methoxy-4-propyl-; 2-Propanone, 1-(4) -hydroxy-3-methoxyphenyl)-; Benzoic acid, phenylmethyl ester; (Z)-Cinnamyl benzoate; 2-Propenoic acid, 3-phenyl-,phenylmethyl ester, (E) -; and Cinnamyl cinnamate.

Abstract

The purpose of this study was to determine the optimal extraction method of potassium from corn cobs in semibatch and batch. In this research, semibatch maceration is a leaching process used to obtain the time needed for the solvent to absorb alkali in corn cob ash. While the batch system maceration is a leaching process used to obtain the amount of time needed for the solvent to reach saturation point. Data collection techniques in this research are: sample preparation and drying of corn cobs, corn cobs pyrolysis, semibatch and batch maceration of corn cobs ash, and determination of alkali content by titration method. From the results, it can be concluded that corn cobss have the potential to be used as a source of alkali because the potassium (K) content in corn cob ash is 25.78%. The moisture content and yield of corn cob ash were 77.5% and 17%, respectively. The saturated solvent time for semibatch maceration was 3.5 days, while for batch maceration it was 12 days. Where at consecutive ratios of 1 gram/25 mL; 2 grams/25 mL; 3 grams/25 mL; and 4 grams/25 mL each had concentration values that still increased from 0.112 N to 0.9672 N; 0.223 N to 3.2364 N; 0.3348 N to 2.0646 N; and 0.558N to 3.6828 N. The highest alkali yield was obtained at a corn cob ash/solvent ratio of 1 gram/25 mL, which was 20.15%.
