      Abstract
      Kasus resistensi bakteri terhadap antibiotik menjadi ancaman serius bagi kesehatan manusia karena menurunkan efektivitas obat untuk mencegah dan menyembuhkan infeksi bakteri. Resistensi dapat disebabkan oleh pengobatan yang tidak tuntas. Salah satunya yaitu bakteri Escherichia coli yang menghasilkan enzim CTX-M yang merupakan jenis dari beta-laktamase yang menghambat kerja antibiotik golongan beta-laktam. Sungkai merupakan salah satu tanaman obat tradisional dan terbukti menghambat pertumbuhan bakteri Escherichia coli. Penelitian ini bertujuan mengidentifikasi senyawa aktif sungkai yang berpotensi menginhibisi beta-laktamase serta analisis interaksi yang terjadi secara in silico. Senyawa aktif daun sungkai ditambatkan ke reseptor beta-laktamase, kemudian dianalisis interaksinya serta diprediksi bioavailabilitas dan toksisitas. Hasil penelitian menunjukan sebanyak 6 dari 19 ligan uji lolos penapisan hingga akhir dan berpotensi menjadi inhibitor beta-laktamase. Senyawa tersebut antara lain, beta-sitosterol, 3,4’,5-thrihydroxy-3,’,7-dimenthoxyflavanone, physcion, isorhamnetin, chrysoeriol, quercetin 3,3 dimetly ether, dan vintexin-2-O rhamnoside.
       
      Cases of bacterial resistance to antibiotic has become a serious threat for human health because they reduce the effectiveness of drugs in preventing and treating bacterial infections. Resistance can be caused by uncomplete treatment. One of example is Escherichia coli bacteria which produces the CTX-M enzyme, that is a type of of beta-lactamase that inhibits the action of beta-lactam antibiotics. Sungkai is one of the traditional medicinal PLANTS and it is proved inhibiting the growth of Escherichia coli. This research aims to identify the active compounds of sungkai that have the potential to inhibits beta-lactamase and analyze interactions of molecular docking. The active compounds of sungkai leaves are docked to the beta-lactamase receptor, then their interactions are analyzed, predicting bioavailability, and toxicity. The results showed that 6 of the 19 tested ligands pass the screening and have the potential to become beta-lactamase inhibitors. The compounds are beta-sitosterol, 3,4’,5-thrihydroxy-3’7-dimenthoxyflavanone, physcion, isorhmaetin, chrysoeriol, quercetin 3,3 dimetly ether, and vintexin-2-O-rhamnoside.
