      Abstract
      Cabai jawa telah lama dikenal sebagai afrodisiak, namun mekanisme kerjanya belum diketahui. Penelitian ini bertujuan mengetahui interaksi senyawa aktif cabai jawa dengan fosfodiesterase tipe 5 (PDE5) (ID: 1UDT) dan menentukan senyawa yang memiliki potensi afrodisiak sebagai inhibitor PDE5 melalui pendekatan in silico. PDE5 sebagai reseptor dan ligan-ligan uji dipreparasi menggunakan software Discovery Studio dan AutoDock Vina. Lima ligan uji guineensine, piperin, piperlongumin, β-sitosterol, dan filfilin dibandingkan dengan sildenafil sitrat setelah diuji stabilitas dan toksisitas ligan. Pemilihan kelima ligan didasari kemiripan struktur ligan dengan hormon steroid. Hasil analisis penambatan molekuler menunjukkan ligan uji yaitu β-sitosterol memiliki nilai ΔG lebih kecil dibandingkan sildenafil sitrat sebesar -10 kkal/mol serta β-sitosterol dan piperin memiliki aktivitas penambatan terbaik dengan %BSS sebesar 63,6% berdasaran analisis visualisasi 2D dan 3D. β-sitosterol dan piperin berpotensi sebagai afrodisiak dengan bekerja sebagai inhibitor PDE5.
       
      Java long pepper (Piper retrofractum Vahl) has known for many years as aphrodisiac in traditional medicine, however the molecular mechanism of this action is not very clear. This study is focused to figure out the interactions between active compounds of long pepper and phosphodiesterase type 5 (PDE5) (ID: 1UDT) and which compounds have aphrodisiac potential as PDE5 inhibitor in silico. PDE5 as receptor and tested ligands were prepared using Discovery Studio and AutoDock Vina. Five tested ligands including guineensine piperine, piperlongumine, β-sitosterol, and filfiline was compared to sildenafil citrate after stability and toxicity test. The five ligand was elected by the structure similarity to steroid hormones. The result of molecular docking showed tested ligands β sitosterol with smaller value of ΔG (-10 kcal/mol) than sildenafil citrate. Piperine and β-sitosterol had best docking activity with %BSS value of 63,6%. β-sitosterol and piperine has potential as aphrodisiac by acting as PDE5 inhibitor.
