Penambahan Molases Untuk Meningkatkan Kualitas Amoniasi Jerami Padi dan Pengaruhnya terhadap Produk Fermentasi Rumen Secara In-Vitro
ABSTRACT: Aimed of this
research was to find out the optimal level of molasses addition at straw rice
ammonization process to N-NH3 production, VFA and microbe protein synthesis.
Material used was rumen fluid of fistula cattle, rice straw, water, urea and
molasses. Treatment tried was level of molasses addition 0%, 15% and 30% on
rice straw which given urea. Research was carried out by experimental method as
in vitro, was conducted use completely randomized design. Variable measured
were N-NH3, VFA and microbe protein synthesis. Intake data entered in data
tabulation and analyzed variance then continued by orthogonal polynomial test.
Research result after ammonization indicated that acidity level and
concentration of released NH3 decrease parallel with addition of molasses
level, and also increase the nutrient content which was crude protein increase
and crude fiber decrease. Variance analysis and Test of orthogonal polynomial
result indicated that treatment of molasses addition have highly significant
effect (P<0.01) and linier respond to concentration of released NH3 after
ammonization. Research result as in vitro indicated concentration N-NH3 and VFA
total decrease while microbe protein synthesis increase. Variance analysis
result indicated that molasses addition treatment at straw rice ammonization
process have highly significant (P < 0.01) on concentration of N-NH3, VFA total
and Microbe Protein Synthesis. Test of orthogonal polynomial for molasses
addition at straw rice ammonization process indicated linier respond on
concentration of NH3 N-NH3 and VFA total, but microbe protein synthesis
quadratic had respond (P < 0,01) white regression equation Y=
52.187-1.089222X + 0.11X2 (r2) 87.27 and (r) 0.9341. Research result could
conclude that molasses addition up to level 30% able to improve quality of
straw rice ammonization process by NH3 fixation so that increase nutrient ingredient,
decrease NH3 that lost to atmosphere, improve utilization of N-NH3 and VFA and
also increase microbe protein synthesis.
