Abstract

It has been conducted the research on Assay of Antibacterial Activity of Ethanolic Extract of Wuluh Starfruit (Averrhoa bilimbi L.) The aim of this research is to determine the antibacterial activity. The initial screening assay conducted on several bacteria including Escheria coli, Pseudomonas aeruginosa, Salmonella typhi, Bacillus subtilis, Staphylococcus aureus, Streptococcus mutans, Vibrio cholerae, Shigella dysenteriae. Then, assay on the Minimum Inhibition Concentration (MIC) was carried out with some variations of concentration: 0,05%; 0,1%; 0,2%; 0,4%; 0,8%; and 1,6%. Test result of MIC was then followed by MKC test (Minimum Kill Concentration) using NA medium. The results showed that on concentration 0,4%; 0,8%; and 1,6% inhibit the growth of bacteria tested. Antibacterial activity of ethanolic extract of wuluh starfruit (Averrhoa bilimbi L.) was conducted by using the diffusion agat method. The result showed that the lowest concentration 0,4% ethanolic extract of wuluh starfruit (Averrhoa bilimbi L.) inhibit the growth of bacteria Shigella dysenteriae, Salmonella typhi, Pseudomonas aeruginosa, Vibrio cholerae, Escherichia coli and Staphylococcus aureus.

Abstract

Analysis of Rhodamin B dye have done in several tomato sauce produced of Makassar city. The research aims to define and analyze levels of compound Rhodamin B in tomato sauce produced Makassar which is source from the sidewalk traders, and industries households by Thin Layer Chromatography (TLC) method for qualitative analysis and spectrophotometry UV-Vis for quantitative analysis. This research can provide benefits to the public about dangers of consuming food that contain of Rhodamin B dye. Extraction with wool yarn, identified by TLC, and analysis by spectrophotometry UV Vis were covered in this study. Research results showed that the four of tomato sauce produced in makassar city did not contain of Rhodamin B dye and that product can be used by the citizen.Key Words : Rhodamin B, Spectrophotometry UV-Vis, Tomato Sauce.

Abstract

One type of pollution that must be taken into concern is lead metal (Pb) as an element that is harmful to humans. Croton leaves contain tannin chemical compounds that able to bind lead (Pb). The research aimed to determine to potency of croton leaves as an adsorbent of lead (Pb). The research used a metal content measurement method based on the adsorption of croton leaves by atomic absorption spectrophotometry (AAS). The results showed that the absorption of lead was based on 3 gram concentrations in the samples, namely sample (1) 0.1181 gram of 1.9991 µg/g, sample (2) 0.3179 gram    of 0.0871 µg/g and sample (3) 0.5117 gram of 0.2171 µg/g. in the use of parameter of the sample concentration it is indicated that at mass 0.1181 gram, the lead metal content showed a maximum absorption of 1.9991 µg/g sample.
