Judul: Production Performance of Local Male Rabbit on Native Grass Application and Various Levels of Tofu Waste
Abstrak: The experiment was carried out to evaluate the use of tofu waste for the concentrate of animal diet. The tofu waste was derived from a local tofu industry at village. It contents protein, energy, mineral, and crude fiber. This is a reason that tofu waste is good for the animals. Rabbits were used as the experimental animal. Four diets containing 20, 40, and 60% of tofu waste and one commercial concentrate were given to the rabbit. Twenty young rabbits (789 ± 0,15; CV= 10%) were used. These animals were divided into four groups. Feed consumption, daily body weight gain, feed conversion, and mortality were recorded. The effect of treatment were studied by ANOVA. The results showed that the effect of treatments was significant on daily body weight gain and feed conversion (P<0,05). Tofu waste can be used as commercial concentrate substitution at 60% rate of native grass and 40% rate of tofu in feed balance for local rabbits.

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: 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.
