Evaluasi Kualitas Bokashi Feses Domba yang Diperkaya Daun Gamal (Gliricidia sepium) terhadap Pertumbuhan dan Produksi Brachiaria humidicola

Abstract

Penelitian ini bertujuan mengevaluasi kualitas bokashi berbahan dasar feses domba yang diperkaya daun gamal berlevel serta pengaruhnya terhadap pertumbuhan dan produksi rumput Brachiaria humidicola. Penelitian menggunakan Rancangan Acak Lengkap (RAL) 6 perlakuan dan 4 ulangan, terdiri atas dua tahapan. Tahap pertama, yaitu K (feses domba 100% tanpa fermentasi), P0 (feses domba 100% difermentasi), dan P1–P4 dengan proporsi feses domba berturut-turut 70%, 65%, 60%, dan 55%, penambahan daun gamal masing-masing 5%, 10%, 15%, dan 20%; seluruh P1–P4 mengandung sisa pakan 5%, sekam bakar 18%, dan kapur 2%. yaitu NPK (Pupuk urea, SP-36, dan KCl) serta P0-P4 dengan formulasi bokashi yang sama seperti pada tahap pertama. Parameter yang diamati meliputi kualitas bokashi, pertumbuhan, dan produksi biomassa B. humidicola. Simpulan penelitian ini adalah bokashi feses domba tanpa penambahan daun gamal (P0) merupakan perlakuan terbaik menghasilkan pertumbuhan dan produksi Brachiaria humdicola.

This study aimed to evaluate the quality of bokashi made from sheep feces enriched with gamal leaves and its effect on the growth and production of Brachiaria humidicola. The study used a Completely Randomized Design (CRD) with six treatments and four replications and consisted of two stages. The first stage included K (100% unfermented sheep feces), P0 (100% fermented sheep feces), and P1–P4, with sheep feces proportions of 70%, 65%, 60%, and 55%, respectively, and Gamal leaf additions of 5%, 10%, 15%, and 20%, respectively. All P1–P4 treatments contained 5% feed residue, 18% rice husk ash, and 2% lime. The second stage consisted of NPK fertilizer (urea, SP-36, and KCl) and P0–P4 with the same bokashi formulations as those used in the first stage. The parameters observed included bokashi quality, plant growth, and biomass production of B. humidicola. This study concluded that bokashi made from feces without the addition of Gliricdia sepium leaves (P0) was the best treatment, as it produced growth and production of Brachiaria humidicola.
