      Abstract
      Stres oksidatif menjadi penyebab timbulnya penyakit degeneratif yang diakibatkan oleh ketidakseimbangan radikal bebas dalam tubuh. Hal ini dapat diatasi dengan menginhibisi protein KEAP1 yang berasosiasi dengan NRF2 dalam mekanisme persinyalan antioksidan seluler. Penelitian bertujuan mengidentifikasi senyawa aktif ekstrak maggot BSF yang berpotensi menghambat aktivitas KEAP1 secara in silico. Metode LC-MS/MS digunakan untuk identifikasi senyawa aktif, dilanjutkan dengan penapisan virtual dan penambatan molekuler dengan aplikasi YASARA Structure dan Autodock 4.2.6. Hasil penelitian menunjukkan dari 45 senyawa aktif dalam ekstrak maggot BSF, terdapat 4 senyawa aktif yang berpotensi sebagai inhibitor KEAP1 berdasarkan analisis energi bebas Gibbs, konstanta disosiasi, interaksi ligan-reseptor, uji bioavailabilitas dan toksisitas, yaitu senyawa dengan CID 73775828, CID 133160, apigenin dan tetradecyl isocyanate. Senyawa dengan CID 73775828 merupakan senyawa terbaik yang berpotensi sebagai inhibitor KEAP1 berdasarkan seluruh parameter yang dianalisis.
       
      Oxidative stress is the cause of degenerative diseases caused by the imbalance of free radicals in the body. This can be overcome by inhibiting the KEAP1 protein which associates with NRF2 in the cellular antioxidant signaling mechanism. This research aims to identify active compounds of BSF maggot extract that have the potential to inhibit KEAP1 activity in silico. LC-MS/MS method was used to identify active compounds, followed by virtual screening and molecular docking using YASARA Structure and Autodock 4.2.6. The results showed that from 45 active compounds in BSF maggot extract, 4 active compounds showed potential as KEAP1 inhibitors based on the analysis of Gibbs free energy, dissociation constant, interaction of ligand-receptor, bioavailability and toxicity prediction analysis. The compounds are CID 73775828, CID 133160, apigenin and tetradecyl isocyanate. The compound with CID 73775828 is the most potential KEAP1 inhibitor according to all analyzed parameters.
