Abstrak: Duck meat has undesire odor. One of the effort that is used to reduce it, is by adding beluntas leaf meal in feed diet. However, the chemical composition of meat and skin need to be learned. Therefore, The purpose of this research is to figure the effect of adding beluntas leaf meal in feed diet to meat and skin chemical composition of domestic male ducks. This reaserch was conducted in Faculty of Animal Science, Bogor Agricultrural University from Juli until November 2005. Fourty five Day Old Ducks (DOD) were raised and given additional beluntas leaf meal to their feed in their 5-10 weeks of age, before being killed. Completely randomize designs was used with three beluntas leaf meal concentration adding treatment (0%; 1% and 2 %). Each treatment consist of three replication and each of it contains five ducks. The result shows that chemical composition of meat and skin thigh is not effected from this adding treatment. Kejovor-ds : donzestic male duck, beluntas leaf nzeal, chenzical conzposition, mea and skin thigh.

Abstrak: Male duck is potential as meat producer, but the ducks meat off-odor limited the consumers preference. Reducing off-odor has success with supplementation beluntas 1% in feed. However the feed conversion were higher than control. To improve feed conversion, using beluntas reduced 0,5%. To covered deficient antioxidant, try added vitamin C and E.The purpose of this research was to study the effect of feeding beluntas leaf meal, vitamin C and vitamin E in improving ducks performances (feed intake, body weight, body weight gain and feed conversion). The diet treatments were commercial diet as control (K), commercial diet+beluntas leaf meal 0.5% (KB), commercial diet+beluntas leaf meal 0.5%+250 mg C vitamin (KBC), commercial diet+beluntas meal 0,5%+400 IU E vitamin (KBE). Ninety six ducks were used for this research and divided into four treatments and three replications. The ducks were reared from one week up to 10 weeks of old. The parameter measured were feed intake, body weight, body weight gain and feed conversion. The results showed that feed intake did not affect. While final body weight and body weight gain of duck feeding beluntas leaf meal 0.5%+vitamin E 400 IU highest obtainable was the best feed conversion.

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.
