“…In this study, it was found that the highest inhibitory zone diameter was 9 mm in AKR3 against the growth of S. epidermidis and AKRX against the growth of C. albicans which were classified as moderate activity. In previous studies, Fibonacci and Hulyadi (2018) have tested antimicrobial activity on Bacillus subtilis and Eschericia coli using soursop leaf extract with successive inhibition zone results of 12 mm and 10 mm [16]. Silitonga (2019) also researched the effectiveness of soursop leaf extract in ethanol and ethyl acetate solvents.…”

This study aimed to test the antimicrobial activity of endophytic bacteria and fungi isolates of soursop (Annona muricata L.) in inhibiting the growth of E.coli, S. epidermidis, and C. albicans. The stages of the research were the isolation of endophytic bacteria, antimicrobial assay, and characterization of potential endophytic bacteria and fungi. Endophytic microbial was isolated from leaves, bark, and root of soursop taken from Praya, Central Lombok. The agar diffusion method was used in the antimicrobial activity assay. Characterization was carried out on endophytic microbes with antimicrobial activity based on colony morphology, Gram staining, and biochemical tests. The antimicrobial activity test results showed that none of the endophytic bacteria and fungi isolates had intense activity inhibiting the test microbes' growth. Isolates with code DN3, DNX, and AKRX had medium activity against E. coli, isolates with code AKR1 had medium activity against S. epidermidis, and isolates with code DN2 AKRX had medium activity against C.albicans. The research results showed that the endophytic bacteria from soursop plants could inhibit the growth of test microbes in the weak to moderate.

“…Water can dissolve some polar compounds contained in A.bilimbi fruit and C.odorata flowers to work to inhibit the test bacteria. Water is a universal solvent that can dissolve secondary compounds of flavonoids, phenols, anthraquinones, alkaloids, and tannins (Fibonacci & Hulyadi, 2018). Secondary compounds can destroy bacterial cell walls and inhibit bacterial growth (Abuga et al, 2020;Prastiyanto et al, 2020).…”

Infectious diseases due to opportunistic bacteria and pathogens are still a health problem. Transmission can be prevented by using an alcohol-based antiseptic liquid or naturally. Averrhoa bilimbi L. fruit plants and Cananga odorata flowers contain bioactive compounds that can inhibit bacterial growth. This study aimed to analyze the infusion activity of Averrhoa bilimbi fruit and Cananga odorata flower in single and combined dosage forms against several frequently pathogenic bacteria in vitro. This posttest-only experimental study with a control group design used the paper disc diffusion method. Observation parameters were the diameter of the inhibition zone on the test bacteria after infusion treatment of 50%, 75%, and 100% A.bilimbi fruit and 100% C.odora flowers, as well as 70% alcohol. The results showed that the diameter of the inhibition zone in the combination treatment of A.bilimbi and C.odorata infusion was significantly different from that of the single preparation (p<0.05). The combination of 100% A.bilimbi and 100% C.odorata (ratio 1:1) produced the greatest effect and was equivalent to 70% alcohol. The average inhibition of the combination infusion of Staphylococcus aureus (17.36mm) and Staphylococcus epidermidis (17.57mm) was greater than that of Escherichia coli (14.48 mm) and Salmonella enterica serovar Typhi (14.12mm). In conclusion, the infusion of Averrhoa bilimbi fruit and the Cananga odorata flower had antibacterial activity, and the combined preparation produced a better inhibitory effect than the single preparation.
