Judul: Energy Digestibility of Cross-Breed Weanling Rabbits as Influenced by Substitution of Soybean Meal of Bauhinia purpurea L
Abstrak: Bauhinia purpurea L. is one of the alternatif ration. Rabbit can be fed Bauhinia purpurea L. due to its high protein content. A major advantage of rabbit meat appears to be in its chemical composition. It is low in fat, cholesterol and salt. A particulary attractive aspect of rabbit production is that it does not have to compete with man for feed sources, nor directly with the traditional species used in the intensive animal industry. ' The energy consumption, digestible energy and energy digestibility value were measured in this experiment. The experiment was conducted in Lab. Ruminansia Kecil, Department of Animal Production Science, Faculty of Animal Science, Bogor Agriculture University. This experiment was carried out during August to October 2002. Twenty male cross-breed weanling rabbits with the initial avarage body weight 853 ± 117 gram were used.

Judul: Dry Matter Digestibility, Protein Digestibility and Nitrogen Retention of Weaning Local Male Rabbit on Substitution Soybean Meal with Bauhinia pururea L.
Abstrak: Bauhinia purpurea L. is a potential legume for rabbit fodder, it contains protein 21.l3%. Rabbit is one of a meat source originating from animal. because rabbit is a prolific animal and easy to rared. Twenty five weaning local male rabbit with average body weight 853 ± 117 gram were used. The aim of this experiment are to recognize the Bauhinia purpurea L. effect that may subtitute soybean meal as a source protein, by detennining the dry matter digestibility, protein digestibility ang nitrogen retention. Completely Randomized Design was used in the experiment. It consisted of five treatments and four replications. The composition of the treatment rations were soybean meal, Bauhinia purpurea L. and concentrate 60%(yellow com 24%, rice brand 12%, wheat brand 20%, coconut oil 2%, CaC03 1% and premix 1%). The ratio of soybean meal: Bauhinia purpurea L. in the diet were (Rl) 40%:0%, (R2) 30%: \0%, (RJ) 20%:20%, (R4) 10%:30% and (RS) 0%:40%. The result showed that the treatment did not significant influence dry matter digestibility, protein digestibility and nitrogen retention. Bauhinia purpurea L. can be used until 40% in the rabbit ration. Key word : Bauhinia purpurea L., soybean meal, dry matter digestibility, protein digestibility, nitrogen retention

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.
