Abstract

The Effect of Dipping Treatment on Faloak (Sterculiacomosa Wallich) Silviculture Properties. Faloak is a species belongsto dry land that tends to decrease in population and may be endangered because of no silvicultural treatments. This study aims to determine the percentage and growth rate of Faloak at seedling level. A direct test through experimental techniques in nursery plots using complete randomized design (CRD) was used. The results of the study show that the percentage of the growth and the growth rate of Faloak seedlings are different depending on the types of treatments and duration of immersion. It is evident that 3 x 12 hours soaking treatment gives different effects compared to the control (without soaking treatment). The percentation of the growth and growth rate of the faloak increase with the increase of soaking times.Keywords:      Sterculiacomosa, Silviculture, Soaking, Percentage of Growth, Growth Rate

Abstract

Faloak (Sterculia comosa Wallich) is a specific species of dry land that has potential antifungal. This study aims to determine the toxicity of barks, leaves, and seeds extracts as an antifungal, and to identify its bioactive compound. The extracts were prepared by multi stage maceration method. Antifungal activity was tested by agar well diffusion method, and minimum inhibition concentration (MIC) and minimum fungicide concentration (MFC) by two-fold serial dilution method were measured. Bioactive compound of active fraction were identified by Liquid Chromatography Mass Spectroscopy (LCMS), Fourier Transform Infrared (FTIR), and Nuclear Magnetic Resonance (NMR). Results showed that the diethyl ether (DE) fraction of seeds is more effective in inhibiting of Candida albicans growth, than the other fractions. Subfraction of DE7 has a higher potency in inhibiting the growth of of Candida albicans. Based on the analysis by LCMS, FTIR and proton NMR, the DE7 sub fractions contain 3-hydroxyoctadecanoic acid (C18H36O3), which is suggested as a mainly compound responsible for antifungal activity.Key words: antifungal, Candida albicans, extractive, Sterculia comosa
