      Abstract
      Penelitian ini bertujuan mengevaluasi efektivitas pupuk organik granul yang diperkaya mikoriza dan lamtoro terhadap kualitas nutrien dan kecernaan in vitro Sorghum bicolor varietas Samurai 1 ratun kedua serta menentukan kombinasi perlakuan optimal terhadap profil fermentasi dan daya cerna pakan. Kandungan dan produksi nutrien menggunakan Rancangan Acak Kelompok faktorial dengan dua faktor, yaitu faktor B adalah jenis pupuk (pupuk organik granul (G), pupuk organik granul + mikoriza (GM), dan pupuk organik granul + lamtoro + mikoriza (GLM)) serta faktor D adalah dosis pupuk (2, 3, 4 ton ha-1) dengan empat ulangan. Fermentabilitas dan kecernaan menggunakan Rancangan Acak Lengkap dua perlakuan (GM4 dan GLM2) dengan tiga ulangan serta dianalisis menggunakan uji T. Hasil menunjukkan interaksi sangat nyata (p<0,01) antara jenis dan dosis pupuk terhadap bahan kering dan fraksi serat. Faktor tunggal jenis dan dosis pupuk berpengaruh sangat nyata (p<0,01) terhadap produksi protein kasar, lemak kasar, dan abu. pH dan NH3 berbeda sangat nyata (p<0,01), Volatil Fatty Acid total tidak berbeda nyata (p>0,05); kecernaan bahan kering dan kecernaan bahan organik tidak berbeda nyata (p>0,05). Simpulan dari penelitian ini adalah kombinasi perlakuan GLM dengan dosis 2 ton ha-1 efektif meningkatkan bahan kering dan fraksi serat. Kombinasi GM4 dan GLM2 efektif meningkatkan pH dan NH3 rumen. This study evaluated the effectiveness of granular organic fertilizer enriched with mycorrhiza and lamtoro on the nutrient quality and in vitro digestibility of second-ratoon Sorghum bicolor var. Samurai 1, and aimed to determine the optimal treatment combination for fermentation profile and feed digestibility. Nutrient content and nutrient production were analyzed using a factorial Randomized Block Design consisting of two factors: Factor B represented the fertilizer type (organic fertilizer (G), organic fertilizer + mycorrhiza (GM), and organic fertilizer + lamtoro + mycorrhiza (GLM)) and fertilizer dose (2, 3, and 4 t ha?¹) each with four replications. Fermentability and digestibility were analyzed using a Completely Randomized Design with two treatments (GM4 and GLM2) with three replications and were analyzed using the T test. The results showed a highly significant interaction (p<0.01) between fertilizer type and dose on dry matter and fiber fraction. The single factors of fertilizer type and dose also had highly significant effects (p<0.01) on crude protein, ether extract, and ash. Ruminal pH and NH3 differed significantly (p<0.01), whereas total volatile fatty acid concentration did not significantly different (p>0.05); dry matter digestibility (DMD) and organic matter digestibility (OMD) did not significantly different among treatments. Conclusion, the GLM treatment at a dose of 2 tons ha-1 effectively increased the dry matter and fiber fractions. The combination of GM4 and GLM2 effectively increased rumen pH and NH3 concentration.
