Judul: The Fat profile of thin tail and fat tail sheep carcasses by using Extracts of Eurycoma longifolia Jack (ELJ)
Abstrak: This research was conducted to observe the influence of extracts Eurycoma longifolia Jack (ELJ) on the fat profile of lamb carcasses. This experiment used factorial design, the first factor was the dosages of ELJ extract (0, 50 and 100mg/kg body weight) the second factor was the breed of sheep (fat tail sheep/DEG and thin tail sheep/DET). The observed variables were serum testosterone, average daily gain, feed consumtion, feed convertion, slaughter weight, hot carcasses weight, weight of pelvic heart kidney fat, percentage of carcasses fat, marbling fat, muscle cholesterol and fatty acid composition. The data were analyzed by analysis of covariance. Initial weigth live as covariable. The results showed that ELJ extract did not have significant effects on serum testosterone, daily gain, feed consumtion, feed convertion, slaughter weight and the fat profile of lamb carcasses. There was significant interaction between level of ELJ extract and breeds of sheep on hot carcass weight and percentage. The weight and percentage of hot carcasses, percentege of carcass fat were significantly higher (P<0.05) in DEG than in DET. These resulted in significantly (P<0.05) lower miristic, palmitic, stearic, linoleic and linolenic DEG fatty acids.

Judul: Pengaruh Bangsa Domba dengan Bobot Potong yang Berbeda terhadap Karakteristik Karkas dan Non Karkas Domba Lokal
Abstrak: Carcass and non carcass characteristics were evaluated in 66 local ewe consisting of 25 Thin tailed sheep (DET), 23 Tail fat sheep (DEG) and 18 Garut sheep (DG). The research was designed using Completly Randomized Design (RAL), 3x3 factorial pattern, with two different factors, among three local ewe (Thin Tail Sheep, Fat Tail Sheep, and Garut Sheep) with three categories of slaughter weights, first category (6-14 kg), second category (15-23 kg) and third category (≥24 kg). The data were analyzed using analizes of varians (ANOVA) and the different among treatmen’s were tested by LS Means. The result showed that carcass percentage only were significantly (P<0.05) influenced by the interaction of breed and slaughter weight category of local ewe. The result showed the largest percentage of carcass was obtained from fat tailed sheep in the second slaughter category (48.84%), and the smallest carcass percentage occured in garut sheep of the second slaughter category (42.63%).

Judul: Closed Knight’s Tour pada Papan Catur Berbentuk Persegi Panjang dengan Ukuran Maksimal 8 × 8
Abstrak: Closed Knight’s Tour merupakan langkah kuda yang mengunjungi setiap kotak pada papan catur tepat satu kali dengan langkah kuda berawal dan berakhir pada kotak yang sama. Graf yang terbentuk dari closed knight’s tour dinotasikan sebagai graf G(m,n), dengan m adalah banyaknya baris dan n adalah banyaknya kolom. Graf tersebut memuat Hamiltonian cycle. Sebuah graf terhubung G adalah graf bipartite jika dan hanya jika graf tersebut tidak memiliki cycle dengan panjang ganjil. Papan catur yang memenuhi syarat cukup untuk memiliki closed knight’s tour adalah papan catur berukuran 5 × 6, 5 × 8, 6 × 6, 6 × 7, 6 × 8, 7 × 8, dan 8 × 8.
