Judul: Pemanfaatan Limbah Udang Sebagai Salah Satu Komponen Ransum Domba Lokal Jantan dan Pengaruhnya Terhadap Kecernaan Lemak, Energi, dan Retensi Nitrogen
Abstrak: Shrimp waste from shrimp industry, composed of head, shell, and a little bit of flesh which is about 30-40% of the shrimp’s weight. Shrimp waste contain 14-19% crude fiber with 12.24% khitin. The aim of this experiment was to examine the level of shrimp waste on nutrient digestibility in ram. Completely Randomize Design with 4 treatments and 4 replications used in this experiment. The treatments were P0 (soybean meal 13.5% + Shrimp waste 0%), P1 (soybean meal 9% + Shrimp waste 10%), P2 (soybean meal 4.5% + Shrimp waste 20%) and P3 (soybean meal 0% + Shrimp waste 30%). The variables measured were ram performance ie. average daily weight gain, feed consumption, feed convertion, lipid digestibility, energy digestibility and nitrogen retention. Data were analyzed using analysis of variance (ANOVA) and the significant result would be continually examined using Duncan Multiple Range Test. The result showed that treatments significantly affected daily weight gain, feed convertion, lipid and energy digestibility. The average of daily weight gain as well as lipid digestibility of P3 was significantly (P<0.05) lower than the other treatments. There were no significant differences between treatments PO, P1, and P2. There were also no significant differencces among treatments on nitrogen retention.

Abstrak: The subtitution of soybean meal with fish meal is used to maximaze and increase the utilization of 70% tea waste, because soybean meal with fish meal contain the most balanced amino acid comparing with others feed component. The Experiment conducted in Small Ruminant Laboratory, Department of Animal Production Science, Faculty on Animal Science, Bogor Agricultural University, from November 2003 until January 2004. 20 Local Lamb with average body weight 20.87±1.8 kg were observed. The experiment design used Completely Randomized Design with five treatments and four replications. The treatments that were given are R1 (10% soybean meal, 0% fish meal), R2 (7.5% soybean meal, 2.5% fish meal), R3 (5% soybean meal, 5% fish meal), R4 (2.5% soybean meal, 7.5% fish meal), R5 (0% soybean meal, 10% fish meal). Data were analysed with ANOVA and followed by doubel Duncan (Steel and Torrie, 1993). The result of this research showed that treatments was not a significantly different affected on feed consumption based on dry matter, average weight gain, feed conversion and Income Over Feed Cost. The average of feed consumption based on dry matter was 978.42±16.52; 999.84±25.00; 1013.21±10.39; 1013.07±15.84; 1010.25±18.47 gram/ekor/hari, average weight gain was 81.35±27.01; 87.30±29.67; 99.21±27.87; 117.06±11.90; 97.22±20.87 gram/ekor/hari, average of feed conversion was 12.97±3.91; 12.89±5.74; 10.85±3.15; 8.71±0.87; 10.74±2.19 gram/ekor/hari. It is concluded that all treatments shown a good substitution 2.5% of soybean meal with 7.5% fish meal is tend to the best of all treatment, because have good feed consumption, average weight gain, feed conversion and Income O ver Feed 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.
