      Abstract
      Daun salam (Syzygium polyanthum) diidentifikasi memiliki senyawa aktif flavonoid. Flavonoid dilaporkan memiliki aktivitas antivirus. SARS-CoV-2 merupakan virus dari penyakit COVID-19. Virus ini dapat ditularkan dari manusia ke manusia. SARS-CoV-2 memiliki beberapa komponen penting salah satunya yaitu 3C-Like Protease. 3C-Like Protease berperan penting terhadap replikasi coronavirus. Penelitian ini bertujuan mempelajari interaksi antara senyawa flavonoid Daun salam (Syzygium polyanthum) dalam menghambat 3C-like Protease SARS-CoV-2 melalui uji in silico menggunakan teknik penapisan virtual serta memprediksi kemampuannya untuk dijadikan sediaan obat oral dengan memprediksi sifat bioavailabilitas dan toksisitasnya. Potensi terbaik terlihat pada Quercitrin dan Myricitrin dengan masing-masing ΔG -8.926 kkal/mol dan -8.858 kkal/mol. Dua senyawa tersebut memiliki berbagai interaksi ikatan hidrogen dan hidrofobik terhadap asam amino pada reseptor, serta diprediksi memiliki bioavailabilitas yang cukup baik dan tidak bersifat toksik, sehingga dapat menjadi kandidat inhibitor potensial enzim 3C-like Protease SARS-CoV-2 untuk dijadikan sediaan obat oral dalam menangani pandemik COVID-19.
       
      Bay leaf (Syzygium polyanthum) has been identified to have active flavonoid compounds. Flavonoids are reported to have antiviral activity. SARSCoV-2 is a virus from the COVID-19 disease. This virus can be transmitted from human to human. SARS-CoV-2 has several important components, one of which is 3C-Like Protease. 3C-Like Protease plays an important role in coronavirus replication. This research aims to study the interaction of flavonoid compounds in bay leaf (Syzygium polyanthum) in inhibiting the 3C-like Protease SARS-CoV-2 through in silico analysis using virtual screening techniques and predicting its ability to be used as an oral drug candidate by predicting its bioavailability and toxicity. The best potency was found in Quercitrin and Myricitrin with ΔG value of -8,926 kcal/mol and -8,858 kcal/mol, respectively. The two compounds have various hydrogen bondings and hydrophobic interactions with the amino acid residues of the receptor and are predicted to have good bioavailability and non-toxic properties so that they become potential inhibitors of 3C-Like Protease of SARSCoV-2 as oral drug candidate in dealing with the COVID-19 pandemic
