Abstrak: Sheep is one of protein source which many people breed in tropic area, including in Indonesia. Beside as source of protein, sheep also used to 11roduce wool, especially in sub tropic countries. Sheep has better adaptation in environment, climate and feed. This study was completely done in 'outdoor laboratoly of IPT Ruluinansia Kecil Departemen IPTP, laboratory of Nutrisi Ternalc Perah Departemen INMT. and photo inicro laboratory, Departemen Biologi Falcultas MIPA Institilt l'ertanian Bogor. This field research was done in July to November 2004. This study used 24 heads local strain nlale sheep aged 8 months old. This sheep was grouped into Tor group based on body weight. Each groups was 6 head sheep.the treatlnents were six. first treatnlent was basal feed (RO), that was for~nulatedf eed based on NRC of sheep (1 989). Second treatment was colnbination of basal feed and 4.5 ppin lead acetate (RI). Third treatment was combination of R1 feed and 1 % yeast protein (R2). Fourth treatment was combination of R2 feed and organic ~nineral Zn 40 ppm. CulO ppm, Cr 2 ppm, and Se 0.3 ppnl (R3). Fifth treatment was colnbination feed of R3 and chitosan (R4). Sixth treatlnent was combination of R3 treatment and Brown weed extract (R5). Wool cutting and collected was done twice, once before treatment's given and second pasca treatment. Taken wool was analyzed of length; weight, density, dianleter and Lead concentration in wool. The design was using groups randoinized design. Then using one way anova (analysis of variance): f~~rther difference was analyzed using lu.uslcal wallis. The results showed that given of lead and supple~iient did not affect to wool quality. It showed in length. weigh. density and dianieter. ICeywords : Sheep. Wool, Lead (Pb), Protein Yeast, Organic Mineral. Chitosan, Brown Sea Weed Extract

Judul: Hubungan Kondisi Fisiologis Domba Ekor Gemuk Jantan dan Palatabilitas Limbah Tauge sebagai Ransum Selama Penggemukan
Abstrak: Sheep farming has been increasing to meet demand of animal protein for human needs. In the livestock business, feed cost is the largest cost. In this study, bean sprouts waste which have no economic value was used as a sheep feed to increase sheep productivity. Productivity of sheep was affected by internal factors and external factors. The external factors are physiological responses and the internal factors are nutrient contents of feed. Bean sprout waste contains 13,63% of crude protein and 49,44% of crude fiber which are useful for sheep feed. The treatment level were P1 (100% concentrate), P2 (75% concentrate + 25% bean sprout waste), P3 (50% concentrate + 50% bean sprout waste), and P4 (25% concentrate + 75% bean sprout waste). The result showed that physiological response and palatability were increased along with the increasing of bean sprouts waste in the feed content. In this research, there were no significant relationship between palatability and physiological response.

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.
