Abstrak: Duck’s hatchery industry produces a diverse weight of Day old Duck’s (DOD) because the hatched eggs have diverse weight. The diverse of DOD weight indicates to cause affect to the performance of ducks. Research was conducted to measure the influence of hatching weight to performance of Alabio duck’s age 0 to 8 weeks. This research used 47 males and 96 females Alabio duck. Alabio’s DODs were separated based on hatching weight, that is small grade (34,39 ± 1.70), medium grade (38.57 ± 0.91), and large grade (43.12 ± 1.98). All ducks had same treatment and maintenance system. This research used randomized completely design with 2x3 factorials of sex and hatching weight. The observed variables ware consumption, average daily gain, weight cuts at 8th weeks, feed conversion, and mortality. From this research, hatching weights didn’t influenced to all performances, however sex can influence to daily gain, body weight at 8th weeks, and feed conversion. Male ducks have daily gain and body weight at 8th weeks bigger than female ducks. Male ducks have lower feed conversion than female ducks.

Abstrak: Alabio male ducks are potential as producer of meat. Many factors influence in ducks production, including feed quality. Feed supplementation such as antioxidant will improve the ducks performance. Beluntas leaf meal, vitamin C and vitamin E could be used as source of antioxidant. The objective of this study was to know the effect of feeding beluntas leaf meal, vitamin C and vitamin E on performances of Alabio male ducks. This study used 96 male Alabio ducks and were reared from one week up to 10 weeks of old. The diet treatments used were commercial feed as control diet (K), control diet + 0.5% beluntas leaf meal (KB), control diet + 0.5% + beluntas leaf meal 250 mg / kg vitamin C (KBC) and feed control + 0.5% beluntas leaf meal + 400 IU vitamin E (KBE). A randomized block design, with 4 treatments and 3 replication was used in this study. The parameters observe were feed consumption, final body weight, body weight gain and feed conversion. The results showed that feeding 0.5% beluntas leaf meal (KB), 0.5% beluntas leaf meal + 250 mg/kg vitamin C (KBC) and 0.5% beluntas leaf meal + 400 IU vitamin E (KBE) did not affect the feed consumption, final body weight, body weight gain and feed conversion. The conclusion of this research did not affect the performances of Alabio male ducks at 1-10 weeks of age.

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.
