Abstract

The use of Antibiotic Growth Promoters (AGPs) in the poultry industry led to farmers’ dependence on antibiotics. Therefore, a safer alternative feed additive, such as fulvic acid, was needed. This study aimed to evaluate the effectiveness of fulvic acid extracted from oil palm empty fruit bunches (FA-OPEFB) as a feed additive on broiler chickens’ digestive tract and intestinal morphology. A total of 150 broiler chickens were used in a Completely Randomized Design (CRD) consisting of three treatments and five replications: P0 (drinking water without FA-OPEFB), P1 (drinking water with 0.1% FA-OPEFB), and P2 (drinking water with 0.2% FA-OPEFB). Observed variables included the relative weight and length of the digestive tract and intestinal morphology. The results showed that the addition of FA-OPEFB in drinking water significantly affected the ileum percentage, villus height, crypt depth, and villus surface area. It was concluded that 0.2% FA-OPEFB in drinking water reduced the relative weight and length of the ileum and improved intestinal morphology in broiler chickens. Key words:           broiler chicken, digestive tract, fulvic acid, intestinal morphology, OPEFB

Abstract

Indonesia sebagai produsen utama kelapa sawit menghasilkan volume limbah padat yang besar, terutama tandan kosong kelapa sawit (TKKS). Limbah ini mengandung kadar lignoselulosa yang tinggi, sehingga sulit terurai secara alami dan berpotensi menimbulkan masalah lingkungan bila tidak ditangani dengan tepat. Proses penguraian TKKS dapat dioptimalkan dengan tambahan bioaktivator, seperti eco-enzyme. Penelitian ini bertujuan untuk mengetahui potensi eco-enzyme sebagai bioaktivator pada proses dekomposisi tandan kosong kelapa sawit. Perlakuan pada penelitian ini dilakukan dengan penyemprotan eco-enzyme dan air, serta dilakukan pengamatan pada hari ke-1, ke-7, dan ke-14. Parameter yang dianalisis adalah kadar C-organik menggunakan metode spektrofotometri, kadar N-total menggunakan metode Kjeldahl, dan diperoleh perhitungan rasio C/N. Hasil penelitian menunjukkan penambahan eco-enzyme memberikan penurunan kadar C-organik yang lebih cepat (6,64%), peningkatan kadar N-total (21,99%), dan penurunan rasio C/N hingga 23% yang mencapai standar kematangan dalam 14 hari. Secara keseluruhan, eco-enzyme berpotensi menjadi bioaktivator yang mempercepat proses dekomposisi TKKS.
