Judul: The Subsitution of Soybean Meal With Tea Waste in Ration Pellet to The Performance of Cross-Breed Weanling Rabbits.
Abstrak: The use of alternative feed can be used to reduce feeding cost. Tea waste is one of bottle beverage industry that can be used as protein resource in rabbits ration due to the high protein contain 27 % (Istirahayu). Twenty female cross-breed weanling rabbits with the initial average body weight 612 ± 89 gram. The experimental design use in this research was completed randomazed design with four treatments and five replications. The data obtained from the experiment was processed using the ANOVA. Whenever a significant different was identified, data processing was continued using the Duncan's Range Test (Steel and Tome, 1993). The amount of treatments shows the level of subtitution of soybean meal with tea waste and concentrated (com 26%, rice brand 20 %, molases 5%, wheat brand 2%, vegetables oil 0.5%, premix 1 %, CaCO3 0.5%), AT0 = 45%: 0% : 55%, AT1 = 30%: 15% : 55%, AT2 = 15% : 30% : 55% and AT3 = = 0% : 45% : 55%. The result shows that the treatment were significantly (p<0,01) higher on dry matter intake, body weight gain and ration convertion. So the rabbit mortality only of treatment AT0. Based on the value dry matter intake, body weight gain and ration convertion the results of this study shows that tea waste can be used as a source of protein in rabbit ranswn up to 45%. The best level of substitution is soybean meal 30 % with 150/0tea waste and 55% concentrate. Keywords: Rabbits, subtitution, soybean meal, tea waste, dry matter intake, body weight gain, ration convertion, mortality.

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: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
