      Abstract
      Diabetes melitus (DM) merupakan penyakit gangguan metabolik yang ditandai dengan tingginya kadar gula dalam darah. Indonesia menempati urutan ke-5 jumlah penderita DM tertinggi di dunia. Acarbose, agen antidiabetik komersial yang bekerja dengan menghambat α-glukosidase, penggunaannya dalam jangka panjang menimbulkan efek samping sehingga senyawa potensial dari bahan alam diperlukan sebagai alternatif. Pengembangan obat baru perlu diprediksi melalui metode in silico agar menghemat biaya dan waktu karena dapat dilakukan dengan cepat secara komputasi. Genus Araucaria, kelompok tanaman yang mengandung biflavonoid, diprediksi dapat menurunkan kadar glukosa darah melalui inhibisi α-glukosidase. Penelitian ini bertujuan mengkaji interaksi molekuler dengan teknik simulasi penambatan molekuler, serta menguji potensi senyawa biflavonoid genus Araucaria sebagai inhibitor α-glukosidase secara in silico berdasarkan struktur dan gugus fungsinya. Hasil penambatan molekuler menunjukkan bahwa ligan uji (5), diprediksi sebagai ligan yang paling berpotensi sebagai inhibitor α-glukosidase dengan nilai ∆G -8,6 kkal/mol, Ki 0,489 μM, dan Binding Site Similarity 68,75% terhadap keseluruhan residu sekitar reseptor.
       
      Diabetes mellitus (DM) is a metabolic disorder characterized by high blood sugar levels. Indonesia ranks 5th with the highest number of DM sufferers in the world. Acarbose, a commercial antidiabetic agent that works by inhibiting α-glucosidase, its long-term use often causes side effects, so potential compounds from natural ingredients need as alternatives. New drug development needs to be predicted through in silico method to save costs and time because it is done computationally fast. The genus Araucaria, a group of plants containing biflavonoids, is predicted to lower blood glucose levels through α-glucosidase inhibition. This study examines the molecular interactions with molecular docking simulation techniques and examines the potential of biflavonoid compounds of the genus Araucaria as α-glucosidase inhibitors using in silico analysis of their structure and functional groups. The molecular docking results showed that the test ligand (5), was predicted to be the ligand with the most potential as an α-glucosidase inhibitor with ∆G -8,6 kcal/mol, Ki 0,489 M, and Binding Site Similarity 68,75% of the total residue around the receptor.
