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.

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: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
