<![CDATA[The Trichoderma asperellum MT02 has been reported to has antibacterial activity against the Extended Spectrum β-Lactamase (ESBL) E. coli based on the screening results through an agar plug method. This study aimed to evaluate the antibacterial activity of T. asperellum MT02 and characterize the composition of the bioactive compounds group possessed in its crude extract. The isolate was cultured in the Malt Extract Broth (MEB) media (static, 27 oC, 15 days). The intracellular metabolites from mycelium were extracted using methanol while extracellular metabolites from broth media were extracted using ethyl acetate. The antibacterial activity of crude extracts was tested using the paper disc diffusion method while bioactive compounds were characterized using the phytochemical method. The results showed that the antibacterial activity of the broth media extract performed a greater activity than the crude extract from the mycelium. The crude extract from mycelia only contained flavonoid and phenol hydroquinone compounds while the crude extract from broth media contains alkaloids, flavonoids, phenols hydroquinone and saponins. Kapang Trichoderma asperellum MT02 telah dilaporkan memiliki potensi sebagai penghasil senyawa antibakteri melawan Extended Spectrum β-Lactamase (ESBL) E. coli berdasarkan hasil penapisan melalui metode agar plug. Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri ekstrak kasar kapang T. asperellum MT02 serta komposisi golongan senyawa bioaktif yang dimiliki. Kapang dikultur pada media Malt Extract Broth (MEB) (statis, 27 oC, 15 hari) di mana metabolit intraseluler dari miselium diekstrak menggunakan metanol sedangkan metabolit ekstraseluler dari media kaldu diekstrak menggunakan etil asetat. Aktivitas antibakteri ekstrak kasar diuji menggunakan metode difusi kertas cakram sedangkan senyawa bioaktif dikarakterisasi menggunakan metode fitokimia. Hasil penelitian menunjukkan bahwa aktivitas antibakteri asal ekstrak media kaldu lebih baik dibandingkan ekstrak kasar asal miselium kapang. Ekstrak kasar kapang asal miselia hanya mengandung senyawa golongan flavonoid dan fenol hidrokuinon sedangkan ekstrak kasar asal media kaldu mengandung alkaloid, flavonoid, fenol hidroquinon dan saponin.]]>
