Efektivitas Amoniasi, Fermentasi, dan Amoniasi Fermentasi dengan Trichoderma harzianum pada Jerami Sereh Wangi (Cymbopogon nardus)

Abstract

ABSTRAK. Penelitian ini bertujuan untuk mengetahui pengaruh ransum yang mengandung azolla (Azolla microphylla) terhadap indeks kuning telur, indeks putih telur dan haugh unit telur ayam. Azolla merupakan tanaman paku air yang pertumbuhan cepat dan dapat dijadikan bahan pakan alternatif untuk ayam petelur. Penelitian menggunakan 48 ekor ayam petelur strain ISA Brown berumur 54 minggu di Fakultas Peternakan, Universitas Padjadjaran. Penelitian ini dilakukan secara eksperimental dengan metode Rancangan Acak Lengkap (RAL) dengan 4 perlakuan (P0= ransum tanpa azolla; P1= ransum dengan 5% azolla; P2= ransum dengan 10% azolla; dan P3= ransum dengan 15% azolla) dan 6 ulangan. Hasil penelitian menunjukkan bahwa ransum yang mengandung azolla berpengaruh tidak nyata (P0,05) terhadap indeks putih telur, indeks kuning telur dan haugh unit telur. Penggunaan azolla sampai taraf 15% menghasilkan nilai yang sama terhadap indeks kuning telur, indeks putih telur dan haugh unit telur ayam.  (Effectiveness ammoniation, fermentation and amoniated fermentation with Trichoderma harzianum in citronella straw (Cymbopogon nardus))  ABSTRACT. The research was conducted to investigate effectiveness of ammoniation, fermentation and ammoniated fermentation with Trichoderma harzianum on citronella (Cymbopogon nardus) straw. The research used Completely Randomized Design (CRD) with 3 treatments: citronella straw with ammoniation treatment (P1), citronella straw with fermentation treatment (P2), and citronella straw with ammoniated fermentation treatment (P3). Each treatment was replicated five times. The parameters measured were an increase in crude protein content, an increase in Total Digestible Nutrient (TDN), a decrease in crude fiber, and a decrease in lignin. Variance analysis was conducted to determine treatment effect and followed by Multiple Range of Duncan to determine difference between treatment. The result showed that treatments give significant effect (P0.05) on increasing of crude protein, increasing of TDN, decreasing of crude fiber and decreasing of lignin. The best value processing of citronella straw was ammoniated fermentation with Trichoderma harzianum. It concluded that ammoniated fermentation with Trichoderma harzianum had the best effectiveness in processing of citronella straw.
