      Abstract
      Scabies merupakan penyakit kulit yang dapat menyerang hewan maupun manusia. Enzim aspartic protease pada Sarcoptes scabiei berperan penting dalam melakukan penetrasi ke dalam kulit. Enzim ini memiliki ligan alami pepstatin yang berikatan hidrogen pada active site-nya (ASP36 dan ASP227). Senyawa pada daun basil memiliki aktivitas sebagai akarisida yang efektif pada caplak dan tungau. Penelitian ini bertujuan menganalisis potensi senyawa aktif daun basil sebagai inhibitor aspartic protease menggunakan penambatan molekuler. Ligan pembanding yang digunakan adalah permethrin. Sebanyak lima dari 53 senyawa aktif daun basil hasil virtual screening dipilih karena memiliki interaksi yang baik dengan aspartic protease. Senyawa-senyawa tersebut kemudian dianalisis profil bioavailabilitas, toksisitas, dan jenis interaksinya. Berdasarkan hasil analisis tersebut terdapat tiga senyawa, yaitu beta-cymene (-8.330 kkal/mol), oleanolic aldehyde (-9.102 kkal/mol), dan alpha-terpinene (-6.646 kkal/mol) yang berpotensi sebagai inhibitor enzim aspartic protease berdasarkan nilai energi bebas ikatan, konstanta inhibisi, dan jenis interaksi yang dibentuk oleh reseptor dengan ligannya.
       
      Scabies is a skin disease that can affect both animals and humans. The aspartic protease in Sarcoptes scabiei has an important role in penetrating the skin. The enzyme has natural ligand pepstatin that hydrogen bond to the active site (ASP36 and ASP227). Compounds in basil leaves are known to have activity as acaricides that are effective on ticks and mites. This study was designed to analyze the potential of active compounds of basil leaves that could as aspartic protease inhibitors using molecular docking. The comparison ligand used permethrin. Five out of 53 active compounds from basil leaves were selected because they have good interactions with aspartic protease. Those compounds then analyzed their bioavailability profile, toxicity, and type of interaction. Based on that analysis, there are three compounds, which are beta-cymene (-8.330 kkal/mol), oleanolic aldehyde (-9.102 kkal/mol), and alpha-terpinene (-6.646 kkal/mol) have potential as aspartic protease inhibitors based on value of free binding energy, dissociation constant, and the type of interaction formed by the receptor with ligands.
