Abstract

The excessive use of antibiotics in the treatment of infections or diseases caused by Staphylococcus aureus is the main cause of antibiotic resistance. Methicillin-resistant S. aureus (MRSA) strains are a serious problem because of their wide distribution in the clinical environment and the living community, so it is necessary to search for antibacterial sources from natural products and traditional medicines such as Kayu racun leaves (Rhinacanthus nasutus). Information regarding the content of the active ingredient and the antibacterial potential of the ethanol extract of Kayu racun leaves is still limited. This study aims to test the phytochemical and antibacterial activity of the ethanol extract of Kayu racun leaves against S. aureus and MRSA bacteria by invitro. The research used an experimental method and was divided into two stages, namely; Phytochemical test of the ethanol extract of Kayu racun leaves using the Thin Layer Chromatography (TLC) method and the antibacterial activity test of the ethanol extract of Kayu racun leaves against S. aureus and MRSA using the paper disc diffusion method. Based on the research results, it can be concluded that the ethanol extract of Kayu racun leaves contains alkaloids, phenols, and flavonoids. The best antibacterial activity was found at a concentration of 100 mg/ml with an inhibition zone diameter of 26.20 mm against S. aureus and 17.90 mm against MRSA.

Abstract

This article discusses the harmful effects of chromium metal on human health and the environment. This review aims to provide an in-depth understanding of its negative implications. Analysis of relevant studies provides a comprehensive picture of how Cr (VI) exposure seriously impacts human health and threatens environmental safety. This review method was conducted by identifying and selecting relevant sources through the scientific journal databases PubMed, Google Scholar, and ScienceDirect with the keywords "Cr(VI)," "health risk," "environmental impact," and "chromium metal" then selected and evaluated by considering the quality of the journal, research methodology, and findings. In terms of human health, exposure to Cr(VI) has been shown to increase the risk of death from cardiovascular disease and has significant carcinogenic potential. The impact is not limited to this; Cr(VI) exposure can also cause respiratory problems and skin irritation in industrial workers. In terms of the environment, releasing Cr(VI) into the air, water, and soil threatens living ecosystems. The impact of Cr(VI) pollution on the water and soil environment is of great concern to the quality of water resources and plant growth. In addition, releasing Cr(VI) into the air around industrial plants can also endanger the health of local communities. Therefore, this article highlights the importance of stricter monitoring of chromium-using industries and promoting safer and environmentally friendly alternatives. Implementing preventive and protective measures is essential to minimize the negative impacts of chromium metal on human health and the environment. Using safer alternatives and environmentally friendly production technologies should also be encouraged to create a sustainable and healthy environment for all living beings.

Abstract

Rubber wastewater contains total ammonia nitrogen (TAN) at levels that can potentially cause pollution if discharged into water bodies without proper treatment. TAN content is one of the commonly used parameters for assessing water quality. Certain groups of bacteria are capable of naturally degrading TAN in the environment. This study aimed to isolate bacteria from rubber wastewater, evaluate their potential to degrade TAN, and identify the most effective isolate at the molecular level. Samples were collected from wastewater treatment ponds using random purposive sampling based on specific criteria. A survey method was used to determine sampling locations, while experimental methods were applied in the laboratory. Bacterial isolation was conducted using the serial dilution technique, followed by inoculation with the pour plate technique. Pure isolates were obtained using the streak plate technique. The degradation potential of the bacterial isolates was tested by inoculating 10% v/v of each isolate into 200 mL of rubber wastewater, followed by incubation at room temperature for six days. TAN levels were analyzed using the phenate method with a spectrophotometer, following the Indonesian National Standard SNI 06-6989.30-2005. Three bacterial isolates (NS-1, NS-2, and NB-1) were obtained from the rubber wastewater. All three isolates demonstrated potential in reducing TAN levels, with final TAN concentrations after incubation ranging from 6.75 to 4.8 mg/L, corresponding to a reduction of 52.50"“66.90%. The most effective isolate in reducing TAN was NS-2. Molecular identification using the PCR-seq method of the 16S rRNA gene revealed that isolate NS-2 showed 99.86"“99.93% sequence identity with Enterobacter sp. This study provides a basis for the development of bioremediation technologies for rubber wastewater treatment to improve aquatic environmental quality.

Abstract

The presence of heavy metals such as lead (Pb) in rubber processing wastewater originates from coagulant materials, vulcanization processes, and raw water contamination. Pb is toxic and persistent, thus requiring proper treatment. This study aims to isolate indigenous bacteria from rubber wastewater that are resistant to Pb and have potential as bioremediation agents. Isolation was performed using the dilution-pour plate method, with selection on a medium containing Pb(NO₃)â‚‚. Resistance tests were conducted at increasing concentrations (100"“350 ppm). Three isolates (IS-1, IS-2, IS-3) were obtained, with IS-3 exhibiting the best growth (μ = 0.641 day⁻ ¹; generation time (G) 1.08 days). Molecular identification of the best bacterial isolate revealed that IS-3 is Pseudomonas protegens. This isolate shows potential as a bioremediation agent for Pb contamination.

Abstract

In this review, the researchers describe a natural process that can remove heavy metals from the environment. The use of Chlorella vulgaris has more potential than other bioremediation processes. Chlorella vulgaris has been recognized as a biomaterial capable of removal and could be a potential alternative method for the physicochemical absorption of heavy metals. The removal of heavy metals using Chlorella vulgaris on living cells can occur rapidly, independent of absorption of metabolism to the cell surface and intracellular absorption. Non-living cells have also successfully removed heavy metals from liquid waste. As one of the innovative removal technologies, it depends on algae's biosorption and bioaccumulation capabilities, which dominate the bioremediation process. This study shows that the composition of Chlorella vulgaris constituents, such as proteins, lipids, carbohydrates, pigments, vitamins, and minerals, which have various amino acid, hydroxyl, carboxyl, and sulfate functional groups, are the main factors in the absorption process of heavy metals in liquid waste, so they have the potential sustainability in its use as a bio adsorbent in the removal of heavy metals in liquid waste in the future.
