ABSTRAK
Penelitian ini telah dilaksanakan selama 3 bulan di Saung Hanjuang Desa
Cijeruk Kecamatan Pamulihan, Sumedang. Tujuan penelitian ini untuk
mengetahui pengaruh kombinasi suplementasi sumber nitrogen, sulfur, dan
fosfor pada proses fermentasi anaerob batang pisang terhadap kandungan
Protein Kasar dan NH3. Penelitian ini dilakukan dengan menggunakan
metode eksperimental. Rancangan percobaan yang digunakan adalah
Rancangan Acak Lengkap (RAL) dengan enam perlakuan yaitu P1= 2,00%
nitrogen + 0,20% sulfur + 0,20% fosfor, P2= 2,00% nitrogen + 0,30%
sulfur + 0,20% fosfor, P3= 2,00% nitrogen + 0,40% sulfur + 0,20% fosfor,
P4= nitrogen 3,00% + 0,20% sulfur + 0,25 fosfor, P5= nitrogen 3,00% +
0,30% sulfur + 0,25% fosfor, dan P6= nitrogen 3,00% + 0,40% sulfur +
0,25% fosfor, diulang sebanyak empat kali. Peubah yang diamati adalah
kandungan Protein Kasar dan NH3. Hasil penelitian menunjukkan bahwa

kombinasi suplementasi nitrogen 3,00% + sulfur 0,40% + fosfor 0,25%
memberikan pengaruh terhadap kenaikan kandungan Protein Kasar paling
tinggi, dan kombinasi suplementasi nitrogen 2,00% + sulfur 0,20% + fosfor
0,20% memberikan pengaruh penurunan kandungan NH3 paling rendah.

Kata kunci : Kombinasi Suplementasi Nitrogen, Sulfur, Fosfor, Protein
Kasar, NH3.

ABSTRACT

This research has been carried out for 3 months at Saung Hanjuang in

Cijeruk-Pamulihan-Sumedang. The purpose of this study was to determine
the effect of supplementation with a combination of sources of nitrogen,
sulfur, and phosphorus in anaerobic fermentation process of banana stem on
the content of crude protein and NH3. This research was conducted using
experimental methods. The experimental design used was a completely
randomized design (CRD) with six treatments : P1 = 2,00% nitrogen +
0,20% sulfur + 0,20% phosphor ; P2 = 2,00% nitrogen + 0,30% sulfur +
0,20% phosphor ; P3 = 2,00% nitrogen + 0,40% sulfur + 0,20% phosphor ;
P4 = nitrogen 3,00% + 0,20% sulfur + 0,25 phosphor ; P5 = nitrogen 3,00%
+ 0,30% sulfur + 0,25% phosphor, dan P6= nitrogen 3,00% + 0,40% sulfur
+ 0,25% phosphor, with four times replication. The measured variables
were crude protein and NH3. The results showed that the combination of
nitrogen supplementation sulfur 3.00% + 0.40% + 0.25% phosphor to give
effect to increase higher in crude protein content. The combination of
nitrogen supplementation sulfur 2.00% + 0.20% + phosphor 0 , 20% give
the effect of decrease lower in NH3 content.
Key word : Combination of Supplementation Nitrogen, Sulfur,
Phosphor, Crude Protein, NH3.
