Abstract


Daun Psidium guajava adalah bahan baku alami yang mengandung senyawa bioaktif, salah satunya adalah tanin. Tanin digunakan pada berbagai industri seperti tekstil, farmasi, kosmetik, dan makanan. Penelitian ini bertujuan untuk mempelajari pengaruh waktu ekstraksi dan rasio solid-liquid terhadap kandungan tanin ekstrak daun Psidium guajava. Daun segar dan kering diekstraksi dengan etanol dengan perbandingan solid-liquid 1/20 dan 1/60 (b/v). Temperatur ekstraksi pada suhu 80 °C dan waktu ekstraksi 30, 45, 60, 75, dan 90 menit. Kadar tanin tertinggi diperoleh pada waktu 60 menit dan perbandingan solid-liquid 1/20 (b/v) masing-masing sekitar 17 % dan 12 % untuk sampel daun kering dan basah. Sebaliknya, penambahan rasio pelarut tidak memberikan dampak yang signifikan terhadap peningkatan kandungan tanin yang diekstraksi. Penelitian ini menunjukkan bahwa peningkatan waktu ekstraksi meningkatkan perpindahan massa tanin sampai tercapai tahap kesetimbangan.

Kata kunci: ekstraksi, tanin, guava, soxhlet, etanol
