Judul: Penggunaan Minyak Biji Bunga Matahari dan Minyak Ikan Lemuru dalam Milk Replacer terhadap Metabolit Darah Anak Domba Prasapih
Abstrak: Milk replacer was artificial milk used to replace ewe’s milk. This study aimed to see the effect of milk replacer containing lemuru fish oil and sun flower seed oil as sheep milk substitution, which evaluated from blood metabolites of pre weaning lamb. This study analyze by completely randomized nested design with 2 factors: time of blood sampling with 2 times (28 and 56 days) and milk replacer treatment factors (P0, P1, P2, P3) were nested within factor time of blood collection with 3 replications. P0=fresh milk from cow, P1=P0+egg yolk+sunflower seed oil, P2 = P0+egg yolk+lemuru fish oil, P3= P0+egg yolk+sunflower seed oil+lemuru fish oil. This study used 12 local lambs that born twins aged 1 to 2 days after born. Parameters were cholesterol, glucose, and triglyceride blood of the lambs. The results of this study showed that the milk replacer treatment had no effect in blood cholesterol, glucose and triglycerides. Treatment of milk replacer increased significantly blood sampling period in blood cholesterol, but there was no effect on blood glucose and triglyceride pre weaning lambs. The addition of sunflower seed and oil lemuru fish oil in milk replacer had no effect on blood glucose and triglyceride, but increased blood cholesterol lambs on 28 days

Judul: Performa Anak Domba Prolifik dengan Pemberian Milk Replacer yang Disuplementasi Minyak Biji Bunga Matahari dan Minyak Ikan Lemuru
Abstrak: One of problems in Indonesian sheep farm is weaning ability that is very low in ewe sheep. Sunflower seed oil and Sardinella fish oil contain essential unsaturated fatty acids that very useful to orphan lamb. This research was aimed to increase performance of prolific lambs supplemented with different kind of oils. This experiment used a Completely Randomized Design with 4 treatments and 3 replications. The treatments were: P0 (cow’s fresh milk), P1 (P0+chicken yolk + 4% sunflower seed oil), P2 (P0+chicken yolk+ 4% Sardinella fish oil), P3 (P0+chicken yolk+2% sunflower seed oil+2% of Sardinella fish oil). The result showed that there were no significant different kind of oils on total dry mater consumptions (g day-1), total crude protein consumptions (g day-1), and total energy consumptions (kal g-1), but it significantly affected total fat consumptions (g day-1), weaning body weight (kg), and body weight gain (g day-1). Performance of prolific lambs that is supplemented Sardinella fish oils equals to performance of prolific lambs without supplementation Sardinella fish oils.

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.
