Abstrak: Levels of fat and cholesterol in lamb meat could be intervened by modified feed using sunflower seed oil (Helianthus annuus) addition that were rich in linoleic fatty acids. The study was purposed to evaluate the effect of sunflower seed oil (MBBM) on the characteristics of lamb fat and cholesterol. The variables observed was the water content, fat content, the ratio of saturated and unsaturated fatty acids composition, cholesterol and numbers of thiobarbituric acid reactive substances (TBARS) in lamb meat. Total of 9 local lambs were divided into 3 groups and were given a treatment ration: P0 (complete ration without MBBM), P1 (complete ration with MBBM 4%) and P2 (complete ration with MBBM 6%). The treatment showed that the addition of the MBBM into the complete rations didn’t affect the variables observed. Generally this study showed that the addition of MBBM into complete ration up to 6% gave positive effect on ratio of saturated and unsaturated fatty acids composition, and it could decrease the level of lamb meat rancidity

Abstrak: Feeding sunflower seed oil, which contains high of unsaturated fats expected to improve the physical and chemical quality of lamb. The aim of this research were to analyze the physical characteristics (pH meat, water holding capacity, tenderness, and cooking losses) and chemical characteristics (moisture content, fat content, and thiobarbituric acid reactive substances (TBARS) value) of lamb meat given rations containing sunflower seed oil. This research was using a descriptive analysis of the 3 treatments: without oil sunflower seeds (P0), sunflower seed oil 4% (P1), and sunflower seed oil 6% (P2), with two replications. Sheep used are a garut sheep that are reared for five months. The results showed that the addition of sunflower seed oil can improve the physical and chemical properties but does not cause rancidity of young lamb chops.

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.
