Pengaruh Dosis Inokulum dan Lama Fermentasi Eceng Gondok dengan Neurospora Crassa Sebagai Bahan Pakan Sumber Energi
Abstract
Eceng gondok (Eichhornia crassipes) adalah tanaman air yang melimpah namun sering dianggap sebagai gulma dan potensi sebagai pakan alternatif untuk unggas karena kandungan nutrisinya yang baik.Namun, tingginya kandungan serat kasar menjadi kendala utama dalam pemanfaatannya. Penelitian ini bertujuan untuk mengetahui pengaruh variasi dosis inokulum dan lama inkubasi terhadap kandungan energi, bahan organik (BO) dan pH eceng gondok yang difermentasi menggunakan Neurospora crassa. Penelitian ini menggunakan rancangan acak lengkap pola faktorial dengan variasi dosis inokulum (1%, 2%, 3%) dan lama inkubasi (5 dan 7 hari). Hasil penelitian menunjukkan bahwa fermentasi eceng gondok pada dosis 1% dan lama fermentasi 7 hari dapat menurunkan kandungan serat kasar. Kesimpulan dari penelitan ini adalah dosis inokulum 1% dengan lama fermentasi 5 hari dapat menurunkan kandungan serat kasar 23,57%, dengan kandungan energi 3753,38 Kkal/kg, kandungan bahan organik 89,77% dan pH 7,47.
