Abstract

Areca nut (Areca catechu L.) is a plant that has many uses and can be used for traditional medicine. Areca nut skin can be used to treat indigestion (dyspepsia), edema and beriberi due to low urine output. This study aims to determine the antibacterial activity of ethanol extract of areca nut peel against the test bacteria Streptococcus mutans and Porphyromonas gingivalis. In this research, the areca nut peel simplicia was extracted using the maceration method with 96% ethanol solvent, after which a liquid ethanol extract was obtained and then evaporated using a rotary vacuum evaporator to obtain a thick extract. After the extract is thick, a Minimum Inhibitor Concentration (MIC) test and a Minimum Bactericide Concentration (MBC) test are carried out. The results obtained in the Minimum Inhibitor Concentration (MIC) test and Minimum Bactericide Concentration (MBC) test on Streptococcus mutans and Porphyromonas gingivalis bacteria were 0.5%. Antibacterial activity test using the agar diffusion method was obtained, for Streptococcus mutans bacteria, the largest inhibitory zone diameter at a concentration of 16% was 12.58 mm and for Porphyromonas gingivalis bacteria at a concentration of 16%, namely 10.93 mm. Based on research, ethanol extract of areca nut peel has antibacterial potential.

Abstract

Pinang seeds (Areca catechu L.) are known for their various benefits, including antimicrobial properties. This study aims to evaluate the antimicrobial activity of ethanol extract from pinang seed against the growth of Candida albicans and Malassezia furfur fungi using the agar diffusion method. The research involved extracting the pinang seed using maceration with 96% ethanol, followed by evaporation using a rotary vacuum evaporator to obtain a concentrated extract. Antimicrobial activity was tested across concentrations of 32%, 16%, 8%, 4%, 2%, 1%, 0.5%, and 0.1%. The results showed that at a concentration of 32%, the ethanol extract produced the largest inhibition zones: 27.78 mm against Candida albicans and 15.51 mm against Malassezia furfur, both categorized as very strong activity. These findings suggest that ethanol extract of pinang seed has significant potential as an antimicrobial agent, particularly against fungal pathogens.

Abstract

Areca nut peel (Arecha catechu L.), a byproduct of areca nut processing, holds potential as a raw material for bioplastics through cellulose utilization. This study aimed to identify bacterial species in areca nut peel capable of producing cellulose. Employing bacterial isolation and identification methods, including morphological and biochemical tests, four bacterial isolates were obtained. Two isolates, identified as gram-negative, were classified under the genus Acetobacter, and two gram-positive isolates were identified as belonging to the genus Lactobacillus. These findings demonstrate the potential use of cellulose from areca nut peel in bioplastic production.

Abstract

Endophytic fungal isolates coded IFBZ5, IFBZ6, and IFBZ7 derived from the stem of the bidara plant (Ziziphus mauritiana Lam.) have shown potential antioxidant properties. This study aims to test the antioxidant activity of endophytic fungal isolates on the bidara plant stem (Ziziphus mauritiana Lam.) by TLC-Autography method and DPPH (1,1-diphenyl-2-picrylhydrazil) free radical silencing. This study used endophytic fungi isolates code IFBZ-5, IFBZ-6 and IFBZ-7 which were fermented for 21 days using MYB medium which was then liquid-liquid extracted with ethyl acetate (1:1) and evaporated. The fermentate extract obtained was then tested for antioxidant activity qualitatively and quantitatively. Qualitative analysis using TLC plates indicated antioxidant activity in all isolates. Quantitative analysis showed that isolate IFBZ7 exhibited strong antioxidant activity with an IC50 value of 50.120 ppm, while IFBZ5 and IFBZ6 showed very weak activity with IC50 values of 2.482.363 µg/mL and 467.847 µg/mL, respectively. The BHT comparator had an IC50 value of 6.778 µg/mL. This shows that the antioxidant power of endophytic fungal isolates coded IFBZ5, IFBZ6 and IFBZ7 is lower than the antioxidant activity of BHT as a comparison.

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

Salam (Syzygium polyanthum (Wight) Walp), belonging to the Myrtaceae family, are noted for their potential antibacterial properties targeting bacteria linked to gastrointestinal infections. This study aims to identify endophytic fungus isolates from bay leaves that produce antibacterial compounds effective against bacteria responsible for gastrointestinal infections, utilizing TLC-Bioautography as a method of analysis. The endophytic fungus from bay leaves was isolated, yielding 17 pure isolates. The findings from the antagonist test of pure isolates of endophytic fungus revealed two isolates with the most significant inhibitory zone diameters: IFSP-8 and IFSP-15. These isolates demonstrated effectiveness against Escherichia coli, Salmonella typhi, Shigella dysenteriae, and Vibrio cholerae bacteria. The active isolate was then extracted by liquid-liquid extraction to obtain ethyl acetate extract for the IFSP-8 and IFSP-15 isolates. The antibacterial activity results of the ethyl acetate extract, analyzed through TLC-Bioautography with a chloroform: methanol (9:1) eluent, indicated the values of Rf1 0,76; Rf2 0,56; Rf3 0,47 for the IFSP-8 isolate. In contrast, the IFSP-15 isolate exhibited the values of Rf1 0,81; Rf2 0,69; Rf3 0,56, demonstrating inhibition of bacteria responsible for gastrointestinal infections.
