Abstract

Bidara leaves (Ziziphus mauritiana Lam) have the ability as an antibacterial, because they contain chemical compounds such as alkaloids, flavanoids, saponins, tannins and phenols. The content of phytochemical substances in bidara leaves accelerates the wound healing process on the outer skin. This study aims to determine the antibacterial activity of the methanol extract of bidara leaves (Ziziphus mauritiana Lam) against test bacteria that cause infectious wounds using the agar diffusion method. This test began with a screening test using 4 test bacteria and the results were inhibiting the growth of Staphylococcus aureus, Pseudomonas aeruginosa, Staphylococcus epidermidis and Propionibacterium acnes at concentrations of 0.1% and 0.5%. Then tested the antibacterial activity of the methanol extract of bidara leaves (Ziziphus mauritiana Lam) using the agar diffusion method and the result was that the ethanol extract of bidara leaves Ziziphus mauritiana Lam) has strong potential as an antibacterial against the test bacteria with the largest diameter of the inhibition zone at a concentration of 4% of 15 .00mm.

Abstract

One type of algae cultivated in Indonesia is the red algae Eucheuma cottoni. Red algae are able to produce active metabolite ingredients to protect themselves from attacks by disease and predators. Initially, algae was only used for vegetables and it was not known what substances were contained in algae. As time goes by, knowledge about algae continues to grow. The red algae Eucheuma cottoni contains the chemical carrageenan, a polysaccharide compound produced from various types of red algae that has antimicrobial, anti-inflammatory, antipyretic, anticoagulant and other biological activities. This research aims to determine the potential of red algae extract as an antibacterial. This research uses a literature study approach where references are obtained through 4 data bases, namely Google Scholar, PubMed, Science Direct and Garuda, then based on the search, 8 journals are obtained that meet the inclusion and exclusion criteria. Based on the results of literature studies, it was found that red algae extract has antibacterial activity against the bacteria Salmonella thypi, Staphylococcus aureus, Staphylococcus epidermidis, Bacilus subtilis, and Escherichia coli. Key words: (Antibacterial, Eucheuma cottoni, Red Algae).

Abstract

Indonesia as a tropical country has a diversity of biological natural resources. This diversity is very beneficial, especially with the large number of plant species that can be used as medicine. One plant that is believed to be used as medicine is lemongrass which has lush and dense leaves. Lemongrass leaves (Cymbopogon citratus) is one of the medicinal plants and can be used as a kitchen spice. Lemongrass plants are very easy to find in Indonesia and contain alkaloids, saponins, tannins, polyphenols, flavonoids, and essential oils. Saponins and essential oils are the main group of chemicals that can exert activity against microbes. This study aims to conduct a screening test of antibacterial activity of the n-hexan fraction of lemongrass leaves (Cymbopogon citrantus) against bacteria that cause skin infections. This research method was conducted experimentally to test the antibacterial activity of lemongrass leaves by screening test. The results in this study, the n-hexan fraction of lemongrass leaves can inhibit the growth of test bacteria Staphylococcus aureus, Pseudomonas aureginosa, Staphylococcus epidermidis, and Propionibacterium acne. It can be concluded that lemongrass leaves (Cymbopogon citrantus) have antibacterial activity.

Abstract

Tempeh is a staple food in Indonesia, known for its nutritional benefits, including 25% protein, 5% fat, 4% carbohydrates, vitamin B12, and rich mineral content. Ensuring the safety and hygiene of tempeh is crucial, especially in preventing contamination by harmful bacteria like Salmonella, which poses serious health risks. This study aimed to detect the presence of Salmonella bacteria in tempeh produced in Palekko Village, Takalar Regency, using Salmonella Shigella Agar (SSA) medium. The method employed was experimental, involving the preparation and dilution of tempeh samples followed by incubation on SSA medium. The results is a no samples detected Salmonella met the Salmonella contamination limit requirements, which were negative/25g.

Abstract

Porang tubers (Amorphophallus muelleri Blume) are known as local plants that contain active compounds such as glucomannan, saponins and flavonoids, which are thought to act as antibacterials. This study was conducted to determine the extent of the ability of ethanol extract of porang tubers to inhibit and kill Helicobacter pylori ATCC 43504, Shigella dysenteriae ATCC 13313, and Vibrio cholerae ATCC 14035 bacteria, by looking at the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) values. The extract was made using the maceration method using 96% ethanol, then tested for antibacterial properties using the liquid dilution method for MIC and the drop plate method for MBC. The results showed the MIC value for the three test bacteria at a concentration of 50,000 ppm. Meanwhile, the MBC value was not achieved even at the highest concentration, which was 100,000 ppm. Based on the results of this study, it can be concluded that the antibacterial effectiveness of ethanol extract of porang tubers is still relatively weak on Helicobacter pylori ATCC 43504, Shigella dysenteriae ATCC 13313, and Vibrio cholerae ATCC 14035 bacteria.

Abstract

Ethanol extract of Kenikir leaves (Cosmos caudatus Kunth) is known to contain bioactive compounds such as flavonoids, tannins, saponins, and phenolics, which exhibit potential antibacterial and antifungal properties. This study aimed to evaluate ycandidiasis. Extraction was performed using maceration with 96% ethanol, yielding an extract with a 10.58% recovery rate. Preliminary screening at 0.1% concentration demonstrated fungal growth inhibition. Subsequent testing of Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal Concentration (MFC) employed the solid dilution technique, revealing both MIC and MFC values at 0.1%. Antifungal activity was further assessed using the agar diffusion method at varying concentrations (2.5%, 5%, and 10%), with ketoconazole as a positive control. The largest inhibition zone (9.22 mm diameter) was observed at 10% concentration. Data were analyzed using one-way ANOVA followed by Tukey’s HSD test, revealing statistically significant differences between 2.5% and 10% concentrations, as well as between 5% and 10%. These findings demonstrate that C. caudatus ethanol extract possesses significant antifungal activity against C. albicans.

Abstract

Increasing antibiotic resistance in gastrointestinal pathogens such as Escherichia coli, Shigella dysenteriae, and Vibrio cholerae encourages the search for new antimicrobial agents. This study aims to evaluate the antibacterial potential of rhizosphere bacteria from porang roots (Amorphophallus muelleri Blume) against the three pathogens through in vitro tests. Isolation was carried out from rhizosphere soil using a serial dilution technique. Eleven isolates were characterized morphologically and tested for antibacterial activity using the agar diffusion method. Two selected isolates (IBRAM-2 and IBRAM-11) were fermented and extracted with ethyl acetate. Antibacterial activity was evaluated using the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) tests with the microdilution and drop plate methods, each with three replications and chloramphenicol as a positive control. The results showed an inhibition zone of 13.2–18.7 mm. The MIC value is 25,000 ppm, while the MBC value ranges from 25,000–50,000 ppm. Although it shows antibacterial activity, the high concentration required indicates weak antibacterial potential.
