Abstract

This study was undertaken to investigate soil Actinomycetes from grand forest park of Pocut Meurah Intan as well as to evaluate their potential to produce antimicrobial compounds. The study was conducted in Laboratory of Microbiology, Faculty of Mathematics and Natural Sciences, Syiah Kuala University from February to July 2012. The research was carried out by using an explorative method with laboratorial evaluation. Three different soil samples were taken from a depth of 10-20 cm below the soil surface and isolated on YM agar medium. During the investigation, 24 isolates were recovered and exhibited various morphological characteristics. The results of the antimicrobial assay showed that 14 isolates (58.33%) were active against one or more of the test organisms. Among the 14 active isolates, one isolate (7.14%) showed antibacterial activity; 9 isolates (64.29%) showed antifungal activity; and 4 isolates (28.57%)  exhibited a broad-spectrum activity against both of the test bacteria and fungi. The inhibitory activity were also varied, ranged from weak (<5 mm), moderate (5-19 mm), to strong (>20 mm).  The highest antimicrobial activity was presented by ATH-17 against Candida albicans (34.50 mm), while the lowest was exhibited by ATH-15 against Escherichia coli (0.20 mm).

Abstract

Tsunami devastated many water infrastructures including the wells. Tsunami areas, land use (rural and urban areas) and land management (agriculture land and home garden) can be leading heavy metals in water quality. The purpose of this research is to investigate how the Tsunami rehabilitation efforts affected the water quality of shallow groundwater by measuring the count of heavy metals (mercury, cadmium and lead by Atomic Absorption Spectrophotometer during the rainy and dry season. Forty-eight water samples’ of wells were collected to determine shallow groundwater from August 2007 to December 2007. The study includes interviews with the owners of the water facilities and sanitary inspection of shallow groundwater wells. The results show the presence Hg and most of Cd in well water are still below the regulatory acceptable limit by Ministry of Health R.I (2002). On the other hand, lead exceeds the regulatory acceptable limit
