Judul: Characteristics of Carcass and Non Carcass Components of Bali and Bali-Angus Crossbreed Cattle on Intensive Rearing System
Abstrak: Carcass and non-carcass are the main product of livestock after slaughter process that has highly economic value. This study aims to evaluate the carcass characteristics and non-carcass components of bali and bali-angus cross cattle. The livestock used in this study were 5 bali bull with an average slaughter weight 235,2 ± 28,0 kg and 5 bali-angus cross bull with an average slaughter weight 338,6 ± 74,8 kg. The variables observed included carcass characteristic components, namely initial weight, slaughter weight, hot carcass and cold carcass weight and percentage, and chilling loss of carcass Furthermore, edible non-carcass weight include fore and hind legs, tail, head, skin, liver, heart, lungs, trachea, kidneys, digestive tract and spleen. The data obtained were analyzed using the T-test. The results showed that the initial weight, slaughter weight, hot carcass and cold carcass weight were significantly higher for bali-angus cross compare to bali cattle (P <0,05). In addition, the weight of fore and hind legs, tail, liver and spleen of bali-angus cross was significantly higher compare to bali cattle (P <0,05), whereas for others components were similar between breeds. Slaughter weight of bali cattle and bali angus cross which have a high slaughter weight will affect the carcass characteristics and non carcass components produced.

Judul: Karakteristik Karkas dan Daging Sapi Bali dan Silangan Bali-Angus pada Pemeliharaan Intensif
Abstrak: Karakteristik karkas dan daging merupakan salah satu faktor penentu kualitas daging yang dihasilkan. Penelitian ini bertujuan membandingkan karakteristik karkas dan daging sapi Bali dan silangan Bali-Angus. Penelitian ini menggunakan total sebanyak 10 ekor sapi terdiri dari 5 ekor sapi Bali jantan dan 5 ekor silangan Bali-Angus jantan. Peubah karakteristik karkas yang diamati yaitu bobot potong, bobot karkas panas, bobot karkas dingin, persentase karkas, tebal lemak punggung, dan luas urat daging mata rusuk (UDAMARU). Peubah karakteristik daging yang diamati yaitu pH, keempukan, susut masak, daya mengikat air (DMA), warna daging, warna lemak, dan skor marbling. Data dianalisis dengan menggunakan prosedur T-test. Hasil penelitian menunjukkan bahwa Sapi Bali-Angus nyata memiliki bobot potong, bobot karkas panas, dan bobot karkas dingin yang lebih tinggi dibandingkan sapi Bali (P<0.05). Rataan bobot potong sapi Bali dan silangan Bali-Angus berturut-turut sebesar 235,2 ± 28,0 kg dan 338,6 ± 74,8 kg. Namun demikian, kedua bangsa sapi memiliki karakteristik daging yang relatif sama yaitu pH, keempukan, daya mengikat air (DMA), susut masak, warna lemak, warna daging, dan skor marbling.

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.
