| Abstract: | Tembakau (Nicotiana tabacum) merupakan tanaman yang mengandung senyawa bioaktif seperti polifenol, flavonoid, alkaloid, terpenoid, dan senyawa aromatik lainnya. Bagian batang tembakau mengandung komponen biopolimer selulosa, hemiselulosa, dan lignin. Penelitian ini bertujuan mengisolasi selulosa diikuti dengan proses konversi menjadi nanoselulosa dengan asam organik dan mengekstraksi senyawa bioaktif dengan etanol 70% dari limbah batang tembakau. Nanoselulosa diperoleh melalui proses hidrolisis menggunakan asam sitrat 5,5 M dan dikarakterisasi menggunakan TEM serta XRD. Penelitian ini menghasilkan nanoselulosa dengan ukuran diameter 2-11 nm dan kristalinitas sebesar 79,78%. Kandungan fenolik, flavonoid, dan kapasitas antioksidan dari ekstrak batang tembakau berturut-turut sebesar 59,17 mg GAE/g, 14,94 mg QE/g, dan 62,09 µmol TE/g. Senyawa bioaktif tersebut diketahui memiliki sifat antibakteri yang baik. Namun wound dressing berbasis nanoselulosa dengan penambahan ekstrak batang tembakau belum menunjukkan adanya aktivitas antibakteri. Tobacco (Nicotiana tabacum) is a plant that contains bioactive compounds such as polyphenols, flavonoids, alkaloids, terpenoids, and other aromatic compounds. The stem portion of tobacco consists of biopolymer components, including cellulose, hemicellulose, and lignin. This study aims to isolate cellulose, followed by its conversion into nanocellulose using organic acids, and to extract bioactive compounds with 70% ethanol from tobacco stem waste. Nanocellulose was obtained through a hydrolysis process using 5.5 M citric acid and characterized using TEM and XRD. The study produced nanocellulose with a diameter of 2–11 nm and a crystallinity of 79.78%. The phenolic content, flavonoid content, and antioxidant capacity of the tobacco stem extract were 59.17 mg GAE/g, 14.94 mg QE/g, and 62.09 µmol TE/g, respectively. These bioactive compounds were found to exhibit good antibacterial properties. However, nanocellulose-based wound dressing supplemented with tobacco stem extract did not demonstrate any antibacterial activity. |
