Judul: Kualitas fisik dan organoleptik daging ayam broiler yang ransumnya diberi penambahan minyak ikan yang mengandung omega 3
Abstrak: Meat quality of broiler chicken is generally determined with chemical, physical and organoleptic quality. Omega-3 fatty acids obtained from fish oil waste as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) is a poly unsaturated fatty acid source that has many benefit for human. The objective of this reseach was to determine the effect of fish oil addition containing omega-3 in poultry feed on the physical and organoleptic quality of broiler chicken meat. The different levels of fish oil (0; 2,5; 5 and 7,5%) were added in poultry feed was given to the chicken until 2, 3 and 4 weeks. The experiment was set up in a completely randomized design with 4x3 factorial pattern. The observed parameters were pH, water holding capacity (WHC), tenderness and organoleptic test. The physical data were analyzed descriptively and organoleptic was analyzed by ANOVA and Duncan's Multiple Range Test. The result showed that the treated breast meat has lower for WHC and more tender than control, but higher pH. The thight meat treated showed that a higher pH and water holding capacity but less tender than control. Organolepticly, the addition of fish oil containing omega-3 fatty acids did not have significantly affect the aroma, colour and texture of meat while taste was affected (P<0,05). Long of feeding omega-3 (2 , 3 and 4 weeks) have significantly affect the meat texture. Keywords: Chicken Meat, Fish Oil, Omega-3, Physical Quality, Organoleptic Quality.

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.
