Pengaruh Penggunaan Perekat Sintetis terhadap Ransum Ayam Broiler
ABSTRACT: The purpose of this
study was learn about the influence added lignosulfonate and bentonite by some
processes production on physical characteristics of pellet form ration. The
experimental design had used a Randomized Completely Design with 4 x 3
factorial and 3 replocats. Factor A were processes production, i.e : A0 =
without processing, A1 = added 5% water spraying, A2 = added 5% hot water
spraying and A3 = steam 45 minute on 1000C and pressure 1.7-1.8 kg/cm2. Factor
R were added binder, i.e: R0 = control ration, R1 = control ration + 1.25%
lignosulfonate and R2 = control ration + 2.5% bentonite. The parameters
observed were water content, specific weght, specific density, packed specific
density, angle of repose, particle size, water activity and durability of
pellet.
Result from this study showed some steam process by autoclave 45 minute
and added binder lignosulfonate and bentonite was obviously influence specific weight,
specific density, packed specific density, angel of repose, particle size,
water activity and durability of pellet by percentage was 0.67 cm, 0.68 g/cm3,
0.75 g/cm3, 1.57 g/cm3, 26.990, even the water activity 0.81 wasn’t good. Added
binder lignosulfonate and bentonite was obviously particle size was 0.67 cm and
durability of pellet was 99.99%. Added lignosulfonate and bentonite by some
process given the best on durability if it compared with commercials ration.
The purpose of this study was to learn about the effect of using binder
lignosulfonate and bentonite during six weeks period. The experimental design
used a Randomized Completely Design with 3 x 4 factorial and 3 replications.
Factor B was storage term (0. 2. 4 and 6 weeks). The parameters observed were
water content, water activity factor higroskopic, particle size, specific
density, bulk density, packed bulk density and pellet durability. The storage
term very significant (P<0.01) influenced the water content and increased
the water activity, decreased the factor higroskopic, particle size, specific
density, bulk density, packed bulk density and durability of pellet. The lowest
water content was 10.82% in 6 weeks. The lowest water activity was 0.74 in 0
week. The highest particle size was 0.669 cm in 0 week. The highest durability
of pellet was 99.95% in 0 week. The highest specific weight was 1.30 g/cm3 in 2
weeks. The highest specific density was 0.738 g/cm3 in 0 week. The highest
packed density was 0.738 g/cm3 in 0 week and the lowest factor higroskopic was
0.79% in 2 weeks.
