Abstract

The cytotoxicity of fishes resulting from the presence of various industrial dyes in industrial effluents is a significant global concern. This study aims to synthesize Reduced Graphene Oxide (RGO) using a natural reducing agent from lime juice. The synthesis process uses a modified Hummer method. The Langmuir and Freundlich Isothermal equations are used to study the adsorption character of MG using RGO. The adsorption kinetics was studied using first and second order equations. The adsorption capacity was measured with concentration 2, 10, 50, and 100 mg L-1 of MG respectively. The results obtained are for the adsorption isotherms following Langmuir and Freundlich. ΔG° shows a negative value which means the adsorption process is spontaneous. The adsorption kinetics follows the first order equation. The adsorption capacity obtained was Qm = 223.21 mg g−1 and a contact time of 20 minutes which made it a strong adsorbent for removing MG from water samples. The removal efficiency of MG by prepared adsorbents from real environmental water sample on the Ulee Lheue beach, Alue Naga beach, and the Krueng Aceh river has been implemented. The results obtained confirmed good work in the applicability of adsorbents for environmental

Abstract

Salmonella typhi is a bacterium that causes salmonellosis which is a serious disease in Indonesia and is still endemic. Until now, the treatment and handling of cases of bacterial infection are still using antibiotics. The comparison of antibacterial effectiveness using turmeric extract, a ginger extract which is a natural ingredient with the antibiotics Ampicillin and Ciprofloxacin on Salmonella typhi isolates from hospital waste and household waste has been conducted. The purpose of this research is to compare the antibacterial effectiveness of Curcuma longa (turmeric) extract, Zingiber officinale (Ginger) extract, Ampicillin, and Ciprofloxacin antibiotics in inhibiting the growth of Salmonella typhi which are isolated from hospital waste and those isolated from household waste. This research is experimental research (experimental), using a control group and the research is carried out in a laboratory. The data collection technique was carried out by measuring the inhibition zone. Size of the inhibition zone of hospital isolates after treated by turmeric and ginger extract is smaller than household isolates. This result indicates that excessive usage of antibiotics will be able to increase the resistance or immunity of Salmonella typhi. Substances which are contained in turmeric and ginger extracts have ability to inhibit the growth of Salmonella typhi, with strong category against hospital isolates and very strong category against household isolates. It is concluded that turmeric and ginger extracts are able to    substitute synthetic antibiotics such as Ampicillin.
