ABSTRAKStaphylococcus aureus merupakan bakteri yang relatif sering dijumpai pada manusia. Beberapa infeksi yang disebabkan oleh Staphylococcus aureus antara lain, bisul, infeksi luka dan pneumonia. Salah satu obattradisional yang dapat digunakan untuk mengobati infeksi yang disebabkan oleh Staphylococcus aureus adalah jamur lingzhi (Ganoderma lucidum). Penelitian dilakukan dengan 5 konsentrasi ekstrak etanol jamur lingzhi, yaitu kontrol negatif (0 µg/ml), 20 µg/ml, 40 µg/ml, 60 µg/ml, 80 µg/ml dan 100 µg/ml dan dilakukan 6 kali pengulangan. Metode yang digunakan dalam uji aktivitas antimikroba yaitu metode difusi kertas cakram. Data zona hambat dianalisis dengan uji Anova One-Way. Hasil penelitian menunjukkan bahwa ekstrak etanol jamurlingzhi (Ganoderma lucidum) dengan konsentrasi 100 µg/ml memiliki rata-rata daya hambat tertinggi yaitu sebesar 18,0 mm (sangat aktif). Dapat disimpulkan bahwa semakin besar konsentrasi ekstrak jamur lingzhi (Ganoderma lucidum), maka akan berpengaruh besar pula terhadap zona hambat bakteri Staphylococcus aureus.Keyword : Antibakteri, Ganoderma lucidum, Staphylococcus aureus, Etanol.ABSTRACTStaphylococcus aureus is a bacteria that can cause infections , such as boils , wound infections and pneumonia. One of the traditional medicines that can be used to treat these infections are fungal lingzhi (Ganodermalucidum). The study was conducted with five concentrations of negative control (0 µg/ml), 20 µg/ml, 40 µg/ml, 60 µg/ml, 80 µg/ml, and 100 µg/ml with six repeats. The method used in the test of antimicrobial activity is paper disc diffusion method. Data of inhibition zone were analyzed by Anova-One Way test. The results showed that the ethanol extract of lingzhi mushroom (Ganoderma lucidum) at concentration 100 µg/ml has highest average of inhibitory regions as big as 18,0 mm. It can be concluded that the greater the concentration of extract of lingzhi mushroom (Ganoderma lucidum) , it will affect the greater the inhibition zone against Staphylococcus aureus.Keyword : Antibakteri, Ganoderma lucidum, Staphylococcus aureus, Etanol.

The antibacterial properties of the compound was done using disc diffusion method. Place and Duration of Study: Department of Pure and Applied Chemistry, Masinde Muliro University of Science and Technology, between January and November, 2019. Methodology: Sequential extraction of dried samples of Kenyan G. lucidum were done using solvents hexane, ethyl acetate and methanol. Chromatographic separation of hexane extract of Ganoderma lucidum was done using spectroscopic data. The compound was assayed against Escherichia coli, Klebsiella pneumoniae, Methicillin–Resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa and Streptococcus pyogenes. Standard antibiotic namely; ampicillin was used as the control. Disc diffusion method was used and zones of inhibition, after respective incubation periods, were used to quantify antibacterial activity. Results: From hexane extract of Ganoderma lucidum, Ergosta-5, 7, 22-triene-3β, 14α – diol (22Z) was isolated. Ethylacetate and methanol extracts produced a mixture of complex compounds. Ergosta-5,7,22-triene-3β,14α-diol (22Z) exhibited significant activity against Methicillin-Resistance Staphylococcus aureus (MRSA) (p=0.022) and Streptococcus pyogenes (p = 0.05). The most sensitive microbe was Streptococcus pyogenes. Conclusion: One major compound, Ergosta-5, 7, 22-triene-3β, 14α – diol (22Z) was isolated, characterized and antibacterial activity determined.

Trichopyton mentagrophytes is a type of fungus that belongs to a group of dermatophytes, and a disease that causes dermatophytosis (ringworm), this fungus likes parts that contain keratin substances such as skin, hair / hair, nails or horns. This study aims to determine the antifungal activity of 50% and 96% ethanol extract. KHM testing was made with a concentration of 2.5%, 5%, 7.5% and 10% with the dilution method to determine KHM. Whereas in testing the width of the inhibitory area (LDH) was carried out after getting the MIC value at concentrations of 10%, 25% and 50% with disc diffusion method to determine the effective LDH and qualitative phytochemical testing. The results showed that 96% ethanol solvent at a concentration of 50% could inhibit the fungus Trichopyton mentagrophytes compared to 50% ethanol as seen from the inhibition zone formed in the width of the inhibitory area. Secondary metabolite compounds found in 50% ethanol extract and 96% ethanol are flavonoids, alkaloids, saponins, tannins, quinones and terpenoids.
