Abstract

The aims of this research are to determine the secondary metabolite content found in the ethanol extract of kweni mango bark (Mangifera odorata Griff) and analyze its potency as a natural antibacterial against Escherichia coli and Staphylococcus aureus. The research was started by maceration process using 96% ethanol solvent, then evaporated at 40-50oC and obtain yield of 20,61% with powder content of 8,34%. Furthermore, phytochemical screening was performed qualitatively to determine the secondary metabolite of the extract. The results showed that ethanol extract of M. odorata Griff bark contained secondary metabolites such as alkaloids, flavonoids, saponins, tannins, terpenoids and phenolics. In this study antibacterial activity was carried out using disc diffusion method in Plate Count Agar media and incubated for 24-48 hours. The results showed that the largest diameter of inhibitory zones formed at a concentration of 15 mg/ml for S. aureus was 12,33 mm with strong classified and for E. coli bacteria with a concentration of 200 mg/ml of 23,67 mm with very strong classified, and almost equal with the result shown by 30 µg tetracycline as positive control, which is 25 mm. The results of this study it can be concluded that the ethanol extract of the kweni mango bark (M. odorata Griff) is bacteriostatic.Keywords: antibacterial activity, Mangifera odorata Griff, phytochemical screening, Escherichia coli, Staphylococcus aureus.

Abstract

There are several species of mulberry that grow and cultivated in Indonesia, and Morus alba var. kanva is one of it. The leaves of mulberry are used as silkworm feeds, while the bark and stem as waste are not utilized. This study aims to analyze the potency of bark and stem of mulberry as an antibacterial Enterococcus faecalis (E. faecalis) which is a cause of the infection of teeth root canal. The bark and stem of mulberry were measured it water contents then macerated with ethanol and the percentage of yield extracts were determined. Furthermore, anti-bacterial activites were conducted with 5 level concentrations of bark and stem extract (25; 50; 75 and 100 mg / mL), ethanol and Tetracycline 250 mg as negative and positive control. The results showed that the bark had a moisture content of 10.7% with a yield value of 25.5%, while the stem had a moisture content of 9.4% and a yield value of 9.8%. the optimum concentration is at the level of 75 mg / mL because at this concentration it has been able to inhibit the inhibitory zone value which is no different from 100 mg / mL.

Abstract

This research aim was to know the chemical distribution of wood (Macaranga hosei King) based on its stem height/axial direction (base, middle and end of stem) and the depth of stem/radial direction (2/3 3/3 rays, 1/3 2/3 rays and 0 1/3 rays). The experimental includes the percentage of alcohol benzene-soluble extractive content, lignin content, holocellulose and ?- cellulose. The result showed base on stem height that the percentage of alcohol benzene soluble extractive, lignin, holocellulose and ?- cellulose content decrease from the base, middle and to the end of stem. Base on depth of stem, the result showed that the percentage of alkohol benzena-soluble extractive content, lignin content, holocellulose and ?- cellulose decreasing from 2/3 3/3 rays, 1/3 2/3 rays and to the part of 0 1/3 rays. The interaction of stem height and depth of stem has significantly affected to the percentage of alcohol benzene-soluble extractive content. The overall result showed that Mahang wood is suitable for used as sawn timbers, wood panels and raw materials for pulp and paper. Keywords: chemical properties, Macarang hosei, stem height, stem depth.
