Abstrak: The waste of mung bean sprouts are recidual bean sprouts production consisting of greenpeal and bean sprout fraction of sieving result for human consumption. This research was conducted to measure carcass composition and meat physical characteristic of the young local male rabbitfattened with feed containing of sprout waste. The carcass composition measurement consisted of the slaughter weight, carcass weight, commercial cut weight, non carcass weight, the weight of carcass component (meat, fat, bone), the percentage of carcass proportion and commercial cut. The physical characteristics of meat which be measure were pH, water holding capacity, drip loss, and meat tenderness. This research used 12 young local male rabbits with age about 12 weekswith treatments of feed100% as control (P1), 85% P1 with 15% waste of bean sprouts (P2), 70% P1 with 30% waste of bean sprouts (P3), and 55% P1 with 45% the waste of bean sprouts (P4). The animals were raised for 8 weeks. The study showed that the provision of sprouts waste treatment did not significantly affect (P>0.05) on carcass characteristic. Result of all treatment on carcass composition tested also showed no significant differences (P>0.05). Weight and percentage of commercial rabbit cut were not significantly differences (P>0.05) in all the commercial cut (foreleg, rack, loin and hindleg). Distributions of carcass components (muscle, fat and bone) were not significantly (P>0.05) different each commercial cuts. The weight and percentage of non carcass showed that not significantly (P>0.05). The physical characteristis of rabbit meat showed that significantly (P<0.05) different in pH variable. It was conclude that bean sprout waste could be used as rabbit feed without decreasing carcass and meat quality.

Abstrak: Rabbits have potential to be developed as meat producer. Rabbit is palatable with almost every roughage, even market waste such as bean sprouts’ waste. Bean sprouts’ waste contains of 13.26% protein and 64.5% TDN. The aim of this research was to evaluate carcass and non carcass composition of male local rabbit age 12 weeks fed with bean sprouts’ waste. Measured variables were slaughter weight, empty body weight, hot carcass weight, cold carcass weight, commercial cuts, carcass composition weight, carcass and commercial cuts proportion, non carcass weight and percentage. This study used 12 male local rabbit fryer with average weight 747±104.543 g. The rabbits reared as long as 12 weeks and slaughtered at age of 6 months. This study used completely randomized design. There were 3 treatments that consisted of 100% of commercial feed (P0), 70% of commercial feed+30% of bean sprouts’ waste (P1), and 50% of commercial feed+50% of bean sprouts’ waste (P2). The data was analysed using ANCOVA with empty body weight and hot carcass weight as covariables. Results showed that the addition of bean sprouts’ waste causing non carcass weight, stomach and hindleg commercial cut weight and percentage were higher than without the addition of bean sprouts’ waste. Addition of bean sprouts’ waste had no effect on slaughter weight, empty body weight, and carcass weight. In conclusion, bean sprouts’ waste can be added fresh to rabbit feed up to 50% in substitute of commercial feed.

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
