Judul: Kajian perbandingan keatas gerak balas ayam hutan merah dan ayam pedaging komersial terhadap manipulasi pemakanan
Abstrak: Beberapa eksperimen telah dijalankan untuk membandingkan gerak balas ayam hutan merah (RJF) dan ayam pedaging komersial (CB) terhadap makanan secara pilihan dan makanan asas yang mengandungi hampas isi rung kelapa sawit (PKC), Ciri-ciri yang diamati meliputi prestasi pertumbuhan, protein dan tenaga yang dimakan, sifat-sifat karkas, tingkah laku, nisbah heterofil: limfosit, mikroflora dan morfologi permukaan usus. Penilaian sifat-sifat karkas pada berat badan yang sama (800 g) menunjukkan RJF lebih berat dari segi keseluruhan karkas dibandingkan dengan CB. Berat otot dan nisbah otot kepada tulang bagi bahagian. tersebut juga lebih tinggi pada RJF. Otot-otot bahagian dada dan paha RJF mempunyai mutu yang lebih baik dari segi kandungan protein, lemak dan kolesterol pada umur dan berat badan yang sama (56 hari, 800 g) dibandingkan dengan CB., Experiments were conducted to compare the responses of the red jungle fowl (RJF) and commercial broiler chicken (CB) to choice feeding and dietary palm kernel cake (PKC). Traits measured were growth performance, protein and energy intakes, carcass characteristics, behaviour, heterophil/lymphocyte ratio, gut microflora and intestinal morphology. Evaluation of carcass characteristics at a common body weight (800 g) showed that RJF had heavier whole breast, thigh and drumstick than CB. Similarly, the muscle weight and muscle to bone ratio of those portions were greater in the former. The muscles of the breast and leg portions of RJF were of better quality than CB in term of protein, fat and cholesterol contents at a common body weight and at a common age (56 days old).

Judul: Persentase karkas dan potongan komersial ayam broiler yang diberi pakan nabati dan komersial
Abstrak: The use of feed is very closely related to meat production. Commercial feed is a mixture of vegetables and animal materials. Reduction of animal material origin could reduce the odor and production costs. Feed vegetable used as a good nutrient content, low fat of animal origin and low prices. This study aims to determine the percentage of carcass and commercial parting of broilers fed vegetable and commercial. This study used 40 samples from 200 broiler chickens Cobb strain reared for 35 days. Each treatment consisted of five replications and each replication consisted of 10 broiler chickens. Variables measured were the weight (final live, carcass, breast, thigh, wing and back), percentage of carcass (breast, thigh, wing and back), meat bone ratio of breast and thigh. The result showed that the final live weight of chicken fed with lower vegetable is 673,15 g /bird, while those given the commercial diet produced about 1628,80 g / bird. Differences carcass, breast, thigh, wings and back on commercial vegetable and row are 387,40 to 1256,80 g, 132,10 to 476,80 g, 119,20 to 362,20g ; from 52,90 to 131,40 g, and from 86,40 to 267,40 g respectively. While the percentage of breast, thigh, wing and back with carcass weight to vegetable feed and commercial feed in a row are 34,11-38,12%; 28,86-30,77%; 10,52-13,75% and 21,48-23,32% respectively. Percentage meat bone ratio of breast and thigh in a row is 1,90-4,32 and1,82-2,78.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
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.
