YUSRAHAMTIKA, 2016 Pemanfaatan Sluri Gas Bio Dengan Input Feses Kambing Dan Biji Durian Terhadap Produktivitas Pastura Campuran. Dibimbing Oleh NURZAINAH GINTING Dan MA’RUF TAFSIN.
Penelitian ini bertujuan untuk melihat pengaruh pemberian sluri gas bio dengan input feses kambing dan biji durian terhadap produktivitas pastura campuran. Penelitian ini dilaksanakan di lahan percobaan Program Studi Peternakan Fakultas Pertanian Universitas Sumatera Utara dimulai dari bulan Maret sampai dengan Agustus 2016. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Petak Terbagi Spilt Plot Design. Perlakuan terdiri atas 2 faktor dan 3 ulangan. Petak utama jenis pastura campuran (RL), yaitu RL 1 Digitaria milianjana dan Stylosanthes guayenensis RL 2 Digitaria milianjana dan Clitoria ternatea. Anak petak dosis pupuk sluri gas bio (ton/ha/thn) dengan input feses kambing dan biji durian. P0 = 0, P1=20, P2=30, P3=40. Peubahyangdiamatiadalah produksi bahan segar, produksi bahan kering, jumlah anakan, tinggi tanaman rumput, tinggi tanaman legum, dan biomassa akar.
Hasil penelitian menunjukkan bahwa jenis pastura campuran memberikan pengaruh yang nyata terhadap produksi bahan segar, produksi bahan kering, jumlah anakan, tinggi tanaman rumput, tinggi tanaman legum, dan biomassa akar. Pemberian sluri gas bio dengan berbagai dosis memberikan pengaruh nyata terhadap porduksi bahan segar dan produksi bahan kering. Kesimpulan Pemberian dosis 30 ton/ha/thnmemberikanhasil produksi pastura campuran paling baik.

ABSTRACT
YUSRAHMATIKA, 2016 : Utilization Of Bio-Gas Slurry With Goat Feces Input And Durian Seeds On Productivity Of Mixed Pasture. Under Supervised by NURZAINAH GINTING and MA’RUF TAFSIN.
The study aimed to look at the effect of bio gas slurry whit goat feces input and durian seeds against productivity of mixed pasture. The research was carried out in filed trials of Animal Science Studies Programme, Faculty Of Agriculture, University Of Sumatera Utara From March Untel August 2016. The design was used in this research were Split Plot Design. The treatments consist of two factor and three replications. Main plot were kind of mixed pasture, namely RL1 (Digitaria milianjana + Stylosanthes guaenensis) and RL2 (Digitaria milianjana + Clitoria ternate) and sub plot were dosage (ton/ha/year) of bio gas slurry, namely P0 = 0, P1 = 20, P2 = 30, P3 = 40. The variable measured were fresh weight, dry matter, number of tillers, height of plants, and root biomassa
The results showed that the type of mixed pasture gave significant effect (P<0,05) on fresh weight, dry matter, number of tillers, height of plants, and root biomassa. The provision of bio gas slurry whit various dosage gave a significant effect (P<0,05) on the content of fresh weight, dry matter, number of tillers, height of plants, and root biomassa of mixed pasture. It is concluded that giving a dosage of 30 ton/ha/year show the best productivity of mixed pasture.
