Abstract

The study aims to find secondary metabolites isolated from leave of pucuk merah (Syzygium Myrtifilium Walp). The method used is maceration, fractionation, column chromatography, thin layer chromatography and identified using Fourier Transform-Infra Red (FT-IR) and Gass Cromatography-Mass Spectroscopy (GC-MS). Phytochemical preliminary test of ethyl acetate fraction contained alkaloids, flavonoids, phenolic and triterpenoids, while the results of phytochemical test against stains 2 ethyl acetate fraction showed a positive test result contains the alkaloid compounds and compounds phenolic. The results of the analysis using cluster bonding FT-IR emergence OH (Hydroksi), C-H (Aromatic), CH3 (Aliphatic), and CO Ether, whereas the MS chromatograms obtained peak (peak) which have a similarity value above 90% according to willey09th.L database. estimates of the results of the analysis can be concluded that the stain 2 ethyl acetate fraction is estimated compound 2,4-di-tersier-butyl-fenol.

Abstract

ABSTRACT             The research to determine “Analysis the Content of Ascorbic Acid in the Red Dragon Fruit by Iodimetri” Vitamin C concentration of postharvest red dragon fruit (Hylocereus Polyrhizus) and at the same time to recognize those the packaging could affected conten of obtained Vitamin C. Analysis process was conducted by iodimetric titration method through the sample of dragon fruit with saving period and packaging varied. The result of completed research find out there was are difference concentration of Vitamin C between packaged dragon fruit and without package, the concentration of Vitamin C in packaged dragon fruit was increase the concentration of Vitamin C from the first day (11,1680 mg/100 gram of sample) to the third day (14,8017 mg/100 gram of sample) and decrease until the fifth day (10,4743 mg/gram of sample), otherwise by another treatment without package the concentration of Vitamin C are increase from the first day (7,4928 mg/100 gram of sample) to the sixth day (19,6784 mg/100 gram of sample) and decreased until the eighth day (14,1395 mg/100 gram of sample). Keywords  : Red dragon fruit (Hylocereus Polyrhizus), Vitamin C dan iodimetric titration.

Abstract

Has been cassava rubber fermentation (M. carthagenensisMÜll) as a raw material for making ethanol with the utilization of fishcork albumin (Channastriata) as nitrogen Saccharomyces cerrevisiae with enzymatic hydrolysis result through 2 stages ieliquification using α-amylase and saccharification stage using gluco -amilase. The best reducing sugar content was obtained at 0.1307%. Based on this research, maximum ethanol content was obtained with 0.5% concentration of nutrient at fermentation time for 232 hours, obtained by result of 12,688% at 5.6 mL distillate volume using gas chromatography method.
