PENGARUH PENGGUNAAN LIMBAH RUMPUT LAUT (Gracilaria verrucosa) TERHADAP EFISIENSI PENGGUNAAN PROTEIN PUYUH JANTAN UMUR 6 – 10 MINGGU (The Effect of Seaweed by Product (Gracilaria verrucosa) on Protein Efficiency of 6 – 10 Weeks Old Male Quail)

Abstract

ABSTRAK

Penelitian bertujuan mengetahui pengaruh pemberian limbah rumput laut (Gracilaria verrucosa) terhadap efisiensi penggunaan protein puyuh jantan. Materi yang digunakan yaitu160 ekor puyuh jantan (Coturnix-coturnix japonica) umur 6 minggu dengan rata – rata bobot badan 120,92 ± 0,48 g.Pakan tersusun dari jagung kuning, bekatul, bungkil kedelai, tepung ikan, Poultry Meat Meal (PMM), premix, minyak kelapa, dan rumput laut dengan PK 20% dan EM 2600 kkal/kg. Rancangan percobaan yang digunakan yaitu Rancangan Acak Lengkap(RAL), 4 perlakuan dan 5 ulangan, T0 : pakan mengandung 0% rumput laut; T1 : pakan mengandung 5% rumput laut; T2 : pakan mengandung 7,5% rumput laut; T3 : pakan mengandung 10% rumput laut. Hasil penelitian menunjukkan bahwa perlakuan tidak berpengaruh nyata (P>0,05) terhadap konsumsi protein, Rasio Efisiensi Protein (REP), dan retensi nitrogen. Hasil penelitian disimpulkan bahwa penggunaan limbah rumput laut sampai level 10% tidak menaikkan atau menurunkan efisiensi penggunaan protein puyuh jantan umur 6-10 minggu.

Kata kunci :limbah rumput laut; puyuh jantan; efisiensi protein.

ABSTRACT

This research aimed to determine the effect of seaweed by product(Gracilaria verrucosa)on protein efficiency of male quail. The materials were six weeks old 160 male quail with average body weight 120,92 ± 0,48 g. Rations were used composed of yellow corn, rice bran, soybean meal, fish meal, Poultry Meat Meal (PMM), premix, coconut oil, and seaweed with 20% protein and metabolizable energy 2600 kcal/kg. Experimental design was Completely Randomized Design (CRD) with 4 treatments and 5 replications.There were T0: diets with 0% seaweed; T1: diets with 5% seaweed; T2: diets with 7,5% seaweed; T3: diets with 10% seaweed. The results showed that the treatment had no significant effect (P> 0.05) on the protein consumption, Protein Efficiency Ratio (PER), and nitrogen retention. It could be concluded that 10% seaweed level did not increase or decrease on protein efficiency of 6-10 weeks old male quail.

Keywords: seaweed by product;male quail; protein efficiency.
