Abstract

Black orchid (Coelogyne pandurata Lindl.) is the one type of orchid that spread to Sumatera and Kalimantan. This species of orchid is sought-after because of its potentially high economic value, so it has often been excessively exploited but not widely cultivated. This research aimed to reveal the influence ofthe extracts of bean sprout and benzyl amino purine (BAP) for the growth of the black orchid (C. pandurata). The research was conducted from May to December 2014 at the Laboratory of Tissue Culture, Department of Biologyand the Aloe Vera Center Pontianak. The experimental design used was the completely randomized design (CRD) with 2 treatment level. The first level was extract of bean sprout (0%; 5%; 7.5%; 10%) and second level BAP (0 ppm; 5 ppm; 7.5 ppm; 10 ppm). The results of the research revealed that the shoots appeared the fastest at the combined treatment of 10% bean sprout extract and 10ppm BAP, i.e. 5.38 days. The number of shoots appearred most at the treatment of 10% bean sprout extract and 10 ppm BAP with shoots appearing at an average of 3.79 ppm. The addition of 5% bean sprout extract resulted in the highest average number of leaves i.e. 3.77.

Abstract

Holothuria atra is marine creature which is potential as a source of antifungal material.This research aims to find out the antifungal activities of the extract of H. atra against the Malassezia furfur fungus that causes tinea versicolor. The extract of H. atra was obtained through a maceration method using methanol. The antifungal activities were tested using Kirby-Bauer disc paper diffusion method on the Saboraud Dextrose Agar (SDA) medium enriched with olive oil. The research used the extract with concentrations of 20%, 40%, 60%, 80%, and 100% with 2% of ketoconazole positive control and DMSO (Dimethyl Sulfoxid) negative control. The secondary metabolite test indicated content of alkaloids, triterpenoids, and saponins in the extract. The test results of antifungal activities showed that alllevels of concentration could inhibit the growth of M. furfur fungus characterized by the formation of a clear zone around the paper disc. The extract of H. atra is fungistatic with a very strong inhibition category. The concentration of 20% is the most effective in inhibiting the M. furfur fungus with a clear zone diameter of 22,16mm.
