Abstract

The effect of sulphuric acid fermentation of processed palm oil bunch hydrolysis and on ethanol and sugar production was conducted. The aim was to investigate the hydrolytic optimum required by Saccharomyces cerevisiae for ethanol and sugar production. About 12.5 g powdered palm oil bunch was used in this experiment. The powder was hydrolized several times using sulphuric acid in several concentration. Sugar, product of  hydrolysis, was detected every one hour using spectrophotometer. The sugar was fermented by Saccharomyces cerevisiae and incubated for several days. Results showed that 2-4% sulphuric acid was oprimum concentration for 30 g/L sugar production. The highest ethanol production 4.94% occurred after two days fermentation.

Abstract

The purpose of this research was to determine whether there is a relationship of senile cataract with blood sugar levels for people with diabetes who checked in BKIM (Balai Kesehatan Indera Masyarakat) Medan. Research was done through two stages, blood sampling and examination of blood glucose levels and data analysis. The patients blood is taken at any time from the patients fingertip. Data were analyzed calculated the correlation relationship where the cataract as the parameters x and y are the blood sugar levels. Correlation calculation results indicate the number r = 0:46, which means there is less close relationship between cataracts and blood sugar levels but percentages show increased in the percent of patients with both cataracts relation to blood sugar levels as well as cataracts with age. From a study of 60 patients aged 45-65 years who suffer from cataracts are less significant association between cataract with blood sugar levels.

Abstract

This reseach aims to determine the composition of secondary metabolites of kirinyuh leaf extract (Euphatorium ordoratum.L) and antimicrobial properties of the extract against Staphylococcus aureus and Escherichia coli. The study was conducted in three phases: the first phase is manufacture kirinyuh leaf extract (Euphatprium odoratum L) through maceration method using N-Hexane solvent and methanol. In stage II, phytochemical screening, namely the identification of secondary metabolites (alkaloids, flavonoids, terpenoids and steroids) to the crude extract of  leaves kirinyuh (Ephatorium odoratum L) in the form of antimicrobial properties of extracts against Staphylococcus aureus and with variations extract concentrations of 0%, 1 %, 5%, 10%, 15%, 20%, and 25% Echerichia coli and incubated at 37°C for 24 hours. The research found that such compounds secondary metbolit alkaloids, flavonoids, steronoid, and saponin, which dominates the secondary metabolites of four that alkaloid. While the screening test of phytochemical N-hexane extracts is not contain metbolit secondary compounds, testing against bacteria possess bioktivitas inhibition at concentrations of 15% with inhibition zone of 1.3 cm on Escherichia coli bacteria and 1.0 cm in bacteria Staphylococcus aureas. This shows kirinyuh leaf extracts have the ability as an anti-microbial.

Abstract

Bligo fruit (Benincasa hispida Thunb) is one of medicinal plants that used to cure typhoid fever which caused by Salmonella typhi bacteria. The aim of this research is to find ont the effect of ethanol concentration as a solvent from Bligo fruit (Benincasa hispida Thunb) extracts as an antibacterial, especially to Salmonella typhi. This simplicia was being extracted with 96% ethanol, 70% ethanol, and 50% ethanol by using maceration method for 3x24 hours. The antibacterial activity test was done by diffusion of agar method to the MHA medium by obserring the resistor zone which formed from 96% ethanol, 70% ethanol and 50% ethanol. The diametres that have been obtained are 6,815 mm for 96% ethanol, 25,223 mm for 70% ethanol while for 50% ethanol there is no resisten zone can be seen. From the result canbe conclude that the best concentration of ethanol that has a great potencial as resistor to Salmonella typhi bacteria is the Bligo fruit (Benincasa hispida Thunb) extracts of 70% ethanol.Key words: Bligo fruit (Benincasa hispida Thunb), Antibacterial, Salmonella typhi.
