Abstract

Sea grapes (Caulerpa racemosa) contain various secondary metabolites with bioactive compounds that function as antibacterial agents. This study aimed to evaluate the antibacterial activity of ethanol extract from sea grapes (Caulerpa racemosa) against Helicobacter pylori. The method used was the agar diffusion technique with paper discs at four different extract concentrations: 500 µg, 600 µg, 700 µg, and 800 µg per disc. Extraction was carried out through maceration using 96% ethanol as the solvent, and antibacterial activity was assessed based on the formation of inhibition zones around the discs. The results showed that all extract concentrations exhibited very strong inhibitory effects on the growth of H. pylori, with inhibition zones of 27.23 mm, 28.51 mm, 29.91 mm, and 31.51 mm, respectively. The higher the extract concentration, the larger the inhibition zone formed. Based on antibacterial activity categorization, Caulerpa racemosa extract demonstrates potential as a strong antibacterial agent against Helicobacter pylori.

Abstract

Infections caused by Staphylococcus aureus are among the leading causes of morbidity and mortality worldwide, particularly due to the increasing resistance to antibiotics. This study aims to evaluate the antibacterial activity of basil leaves (Ocimum basilicum L.) against S. aureus using the agar diffusion method. This laboratory experimental study used a completely randomized design: extract concentration treatments (100µL, 200µL, 300µL, 400µL), a positive control (synthetic antibiotic @amoxicillin), and a negative control (distilled water), each with three replications. The data were analyzed using non-parametric statistics, as the data were not normally distributed and lacked homogeneity. The Kruskal-Wallis ANOVA was used to determine differences between treatments. The results showed that basil leaf extract exhibited significant antibacterial activity, with all concentrations inhibiting the growth of S. aureus. The highest inhibition zone was observed at the 400µL concentration, with an average diameter of 9.28 ± 0.36 mm. These findings suggest the potential of basil leaves as a natural antibacterial source for developing alternative therapies against S. aureus infections.

Abstract

Salmonella typhi is the primary bacterial cause of typhoid fever, which remains a serious health concern in developing countries, including Indonesia. This study aims to evaluate the inhibitory activity of sea grape (Caulerpa racemosa) extract against Salmonella typhi. The extract was obtained through maceration and tested using the agar diffusion method with paper discs at various concentrations (100, 200, 300, and 400 µg/disc). The results showed that C. racemosa extract inhibited the growth of S. typhi with average inhibition zone diameters of 25 mm (100 µg), 27.3 mm (200 µg), 28.8 mm (300 µg), and 29.5 mm (400 µg). The negative control (distilled water) showed no antibacterial activity. Based on classification, all concentrations exhibited very strong antibacterial activity. A higher extract concentration corresponded to greater inhibitory effect. These findings suggest that C. racemosa has potential as a natural antibacterial agent against S. typhi and may be further developed for alternative typhoid treatment.

Abstract

This study aims to test the antibacterial activity of Scleria sumatrensis extract against Propionibacterium acnes, a bacteria that causes acne. Extraction was carried out using the maceration method using 96% ethanol, and the antibacterial activity test was carried out using the diffusion method using a concentration of 100–500 ?g/disc. The results showed that the extract provided moderate antibacterial activity at a concentration of 100 ?g/disc and increased to strong at a concentration of 200–500 ?g/disc. S. sumatrensis extract contains secondary metabolite compounds such as phenolics, flavonoids, alkaloids, tannins, steroids, and terpenoids that play a role in inhibiting the growth of P. acnes through various mechanisms, including cell membrane damage, inhibition of protein synthesis, and disruption of bacterial metabolism. Based on the results of the study, S. sumatrensis extract has the potential as a natural antibacterial alternative for acne treatment without significant side effects or the risk of antibiotic resistance.

Abstract

Staphylococcus aureus bacteria is one of the important pathogens that can cause various types of infections, ranging from mild ones such as folliculitis and impetigo to life-threatening conditions such as nosocomial pneumonia, osteomyelitis, endocarditis, sepsis, and toxic shock syndrome. Due to its ability to develop resistance to antibiotics, new alternative treatments are needed, one of which is from natural ingredients. In this study, the antibacterial activity of Scleria sumatrensis extract was tested against Staphylococcus aureus with a concentration variation of 100 - 500 µg / disc. The results showed that at a concentration of 100 ?g / disc, the extract provided antibacterial activity in the moderate category, while at a concentration of 200 to 500 ?g / disc, the activity produced was included in the strong category. These findings indicate that Scleria sumatrensis extract has the potential as a natural antibacterial agent against Staphylococcus aureus, so it is worthy of further development as an alternative therapy for infections caused by S. aureus bacteria.

Abstract

Diseases caused by bacteria infections are renowned for hurting human health and may become fatal when not treated with appropriate medical therapy. Meanwhile, several bacteria, including Mycobacterium smegmatis, Escherichia coli, and Salmonella typhi, are resistant to numerous antibiotics. Therefore, this study aimed to find new compounds from plants with antibacterial potential. The results showed that based on phytochemical screening, Dendrophthoe pentandra mistletoe leaf on Citrus microcarpa Bunge plants had compounds with antibacterial activity, namely alkaloids, flavonoids, tannins, and phenolics. According to Gas Chromatography-Mass Spectrometry (GC-MS) analysis, eight compounds have antibacterial properties, namely 2-Myristynoyl pantetheine; 2H-Indeno[1,2-b]furan-2-one, 3,3a,4,5,6,7,8,8b-octahydro-8,8-dimethyl; Acetamide, N-methyl-N-[4-(3-hydroxypyrrolidinyl)-2-butynyl]-; Ethyl iso-allocholate; a-D-Glucopyranoside, methyl 2-(acetylamino)-2-deoxy-3-O-(trimethylsilyl)-, cyclic methylboronate; tert-Hexadecanethiol; Sarreroside; and d-Mannose. D. pentandra mistletoe leaf extract had a better effect or activity on inhibiting the growth of M. smegmatis than E. coli and S. typhi. It was concluded that D. pentandra mistletoe leaf on Citrus microcarpa Bunge plants had antibacterial activity.
