Judul: Persentase dan Kualitas Karkas Itik Cihateup-Alabio (CA) pada Umur Pemotongan yang Berbeda
Abstrak: Low demand of duck meat is influenced by its quality. Generally, ducks slaughtered at 8 weeks have low carcass quality. Slaughter age is expected to influence carcass quality. Therefore, the study of carcass quality in different slaughter ages (8, 10, and 12 weeks) is needed. This research used 32 males and 18 females cihateup-alabio (CA) ducks. Ducks were grouped by hatching period. The experiment design was randomized block factorial (3x2). Treatments were slaughter age and sex. Traits measured were slaughter weight, percentage of carcass and its parts, physical and sensory quality of duck carcass. The result showed that interaction of slaughter age and sex affect slaughter weight. The higher slaughter age resulted higher breast and abdominal fat percentage, but had smaller thigh percentage. Sex had no effect on carcass percentage and its parts. Higher slaughter age and male sex showed better phisycal carcass quality. Differences in slaughter age and sex had no effect on panelist preference. This research concluded that higher slaughter age produces better carcass percentage and quality.

Judul: Performa Karkas dan Profil Asam Lemak Daging Entok (Cairina moschata) Umur 8 Minggu pada Peternakan Tradisional di Kabupaten Bogor
Abstrak: Muscovy duck (Cairina moschata) is one of poultry that the weight of body can reach 3.5 kg to 6 kg. These advantages should make this waterfowl as a source of protein for food. However, the cultivation are not optimal, because of the lack information of feed nutrients and nutrient content of muscovy meat. This study was aimed to determine the nutrient content of feed which commonly given by the traditional muscovy breeder, carcass performance was and characteristics of fatty acids at 8 weeks of age of muscovy duck meat. This study was conducted through asking quesionaers to traditional breeders in Bogor, feed sampling, and laboratory analysis. The informations showed that generally feed which given to the muscovy in 6 traditional breeders have a low content of crude protein ranged between 9.03% - 11%. The low nutrient content of feed cause a low weight body in muscovy duck. Male duck has a higher weight than the female duck. Muscovy meat contains some saturated and unsaturated fatty acids (MUFA and PUFA) are both fairly high abortion. UFA concentration are higher more than SFA concentration. Palmitic acid and Steraic acid which is a saturated fatty acid, Oleic acid is a monounsaturated fatty acid, and Linoleic acid is an unsaturated fatty acid are some fatty acids in highly concentrations produced muscovy breast meat and thigh male. The amount of fatty acids respectively reached 16.62%, 6.26%, 30.30%, and 11.98%. The concentration of fatty acids in thigh meat tended to be higher than the concentration of fatty acids in breast meat.

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.
