KUALITAS NUTRISI SILASE JERAMI PADI YANG DISUPLEMENTASI DAUN TURI (Sesbania grandiflora)

Abstract

Rice straw is characterized by high crude fiber content and low crude protein, making it a
feed ingredient with limited nutritional value. This condition requires increasing its nutritional
value through the addition of protein-rich supplements. The study aimed to examine the effect of Sesbania grandiflora leaf meal as a supplement on the nutritional composition of rice straw
silage. A completely randomized design (CRD) with four treatments and four replications was
used in this study, resulting in a total of 16 experimental units. The study was conducted at the
Plant and Feed Laboratory, Bukit Campus, Faculty of Animal Husbandry, Udayana University.
The treatments used included: P1 = 85% rice straw + 10% pigeon pea leaf meal + 5% molasses,
P2 = 75% rice straw + 20% pigeon pea leaf meal + 5% molasses, P3 = 65% rice straw + 30%
pigeon pea leaf meal + 5% molasses, P4 = 55% rice straw + 40% pigeon pea leaf meal + 5%
molasses. Statistical analysis showed that supplementation with turi leaf meal significantly
reduced dry matter and crude fiber content while increasing organic matter and crude protein
content in rice straw silage. Meanwhile, silage pH did not change significantly between
treatments. Treatment P4 (40% turi leaf meal) provided the best results, with the highest crude
protein and organic matter content, and the lowest crude fiber content compared to the other
treatments. These results indicate that the use of turi leaf meal or Sesbania grandiflora up to 40%
is the optimal level for increasing the nutritional value of rice straw silage.

ABSTRAK 

Jerami padi dicirikan oleh kandungan serat kasar yang tinggi serta protein kasar yang
rendah, sehingga menjadikannya sebagai bahan pakan dengan nilai nutrisi terbatas. Kondisi ini
memerlukan peningkatan nilai gizinya melalui penambahan suplemen kaya protein. Penelitian
bertujuan untuk mengkaji pengaruh tepung daun Sesbania grandiflora sebagai suplemen
terhadap komposisi nutrisi silase jerami padi. Rancangan acak lengkap (RAL) dengan empat
perlakuan dan empat ulangan digunakan dalam penelitian ini sehingga total terdapat 16 satuan
percobaan. Penelitian dilaksanakan di Laboratorium Tumbuhan dan Pakan Kampus Bukit
Fakultas Peternakan Universitas Udayana. Perlakuan yang digunakan meliputi: P1 = 85%
jerami padi + 10% tepung daun turi + 5% molase, P2 = 75% jerami padi + 20% tepung daun
turi + 5% molase, P3 = 65% jerami padi + 30% tepung daun turi + 5% molase, P4 = 55% jerami
padi + 40% tepung daun turi + 5% molase. Analisis statistik menunjukkan bahwa suplementasi
tepung daun turi secara signifikan dalam menurunkan kadar bahan kering dan serat kasar
sekaligus meningkatkan kadar bahan organik dan protein kasar dalam silase jerami padi.
Sementara itu, pH silase tidak berubah secara signifikan antar perlakuan. Perlakuan P4 (40%
tepung daun turi) memberikan hasil terbaik, dengan kadar protein kasar dan bahan organik
tertinggi, serta kadar serat kasar terendah dibandingkan dengan perlakuan lainnya. Hasil ini
memperlihatkan bahwa penggunaan tepung daun turi atau sesbania grandiflora hingga 40%
merupakan level optimal untuk meningkatkan nilai nutrisi silase jerami padi.
