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.

Abstrak: Alternative feed rations to reduce the use of commercial waste are sprouts. This study aimed to compare the performance of local male rabbits fed by complete sprouts waste pellet shaped to substitute the use of elephant grass. This study used a completely randomized design with 4 treatments and 4 repetitions. There were 16 local male rabbits aged 2 months with an average live weight 879.375 + 60.874 g head-1. Treatments consisted of P0 = 15 % of elephant grass + 85 % of concentrate, P1 = 10 % elephant grass + 5 % of sprouts waste + 85 % concentrate, P2 = 5 % of elephant grass + 10 % sprouts waste + 85 % concentrate, P3 = 15 % of sprouts waste + 85 % concentrate. Data were analyzed by analysis of variance (ANOVA). The results showed that the use of waste to the extended 15 % of sprouts waste pellets could substitute the usage of elephant grass and reduce the price of feed to give a good performance on the local male rabbits. Daily weight gain of rabbits given pellet P2 and P3 is 18.954 to 19.785 g day-1 with a final body weight greater than P0 and P1. The highest pellet consumption is the treatment of P2 and P1, the consumption of P3 pellet treatment is not too high and shows the average final body weight better than others. It also could decrease the cost.

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.
