      Abstract
      Obesitas telah menjadi permasalahan gizi yang mendunia. Kejadian ini ditandai oleh IMT ≥ 30 kg/m2. Kandungan β-sitronelal dan β-sitronelol dalam serai wangi pada penelitian in vivo terbukti dapat menurunkan berat badan melalui peningkatan aktivitas saraf simpatik yang berdampak pada penurunan nafsu makan, namun potensinya sebagai inhibitor lipase pankreas in silico belum diketahui. Penelitian ini bertujuan menguji potensi senyawa aktif serai wangi sebagai inhibitor HPL 1LPB in silico. Metode yang digunakan yaitu preparasi protein dan ligan, validasi gridbox, penapisan virtual, visualisasi interaksi residu asam amino, serta analisis bioavailabilitas dan toksisitas. Hasil penelitian menunjukan bahwa sebanyak 26 dari 47 ligan uji hasil studi literatur dan analisis LCMS diketahui memiliki kemampuan yang baik dalam menghambat lipase pankreas (Kode: 1LPB) dibandingkan dengan MUP berdasarkan parameter energi ∆G, Kd, dan %BSS. Ligan uji apigenin-8-C-glucoside yang termasuk ke dalam golongan senyawa fenolik merupakan ligan yang memiliki penghambatan paling kuat dengan nilai ∆G -8,326 kkal/mol, Kd 0,78 µM dan %BSS sebesar 93% serta memenuhi analisis bioavailabilitas dan toksisitas. Oleh karena itu serai wangi diprediksi memiliki potensi sebagai antiobesitas melalui penghambatan lipase pankreas dan aman apabila dikembangkan menjadi kandidat obat.
       
      Obesity has been one of nutrient problems in the world. This is indicated by IMT ≥ 30 kg/m2. The component of β-citronellal and β-citronellol in serai wangi, based on this research in vivo discovered that it can reduced the weight through incresing sympathic neuron causing the reducing of apatite, yet its potency as inhibitor as pancreatic lipase in silico was not proved. The research is intended for testing the potency of active compounds of Serai Wangi as inhibitor of HPL 1PLB in silico. The method applied was protein and ligan preparation, gridbox validation, virtual screening, amino acid visualization interaction, with bioavailability and toxicity analysis. The research found that the number of 26 from 47 Ligan as the result of literature study and LCMS analysis was discovered having good ability in inhabiting pancreatic lipase (code: 1LPB) compared with MUP based on ∆G, Kd, dan %BSS parameters. Ligand of apigenin-8-C glucoside belongs to phenolic compounds as the most potential ligan in inhabiting pancreatic lipase with the value ∆G -8,326 kcal/mol, Kd 0,78 μM and % BSS up to 93% and fulfilling bioavailability and toxicity analysis. That is why serai wangi was predicted having the potency of antiobesity through inhabiting pancreatic lipase and safe for candidate medicine.
