Judul: The Performanee of Mule Duck with Different Level Addition of Kangkung (Ipomoeae aquatica) in Ransum.
Abstrak: Stress is easily happen on mule duck because it has high nervous characteristic like its dam. Stress will reduce mule duck performance and one of solution to handle stress is by giving antistress or transquilezer. Kangkung is one of water pland and it can be use as transquilezer so it is appropiate to be used antistress medicine for mwe duck. Kangkung have content protein, fat, cartbohidrat, calsium, phosphor, iron, vitamin A, B I, C, caroten, sitosterol and hentriacontan which are needed for body and to increase mule duck performance. This experiment purpose are to study whether kangkung performance also to find the right kangkung suplementation dosage to increase mule duck perfonnance as meat ripe. This experiment was done in September up to November 2002 in Laboratory of Science Produce Livestock Poultry Block B, Department of Science Produce Livestock. Faculty Of VeterinaIy, Bogor Institute of Agriculture. This experiment used 80 mule duck with age of 5-10 week without unsexed, commercial feed and kangkung. This experiment used complety randomized design with four treatment with the level 0%, 5%, 10% and 15%. Every treatment consistfor repetation so it were obtained 16 unit research and every reseach unit consist five mule duck. The variable which were observed are feed consumption. body weight, body weight grow, feed convertion and Income Over Feed and Duckling Cost. Data were analized with anova and continued with Fisher's lest significant different. The experiment of varian analyzed shows that kangkung suplementation in feed significantly influenced into final body weight, body weight grow, but this not significantly influenced for feed consumption during this research. Kangkung suplementation 15% gives the best feed convertion which is 3,62 and give the highest Income Over Feed and Duck Cost. Keyword: mule duck, kangkung (Ipomoea Aquatica), performance, ransum

Judul: Carcass and Non Carcass Percentage of Mule Duck with Vitamin C Supplementation.
Abstrak: Mule duck is easy to get stress that started in 3-4 week of age. One solution to solve this condition is giving an anti stress. The anti stress that more used in poultry is vitamin C (ascorbic acid). If it trough, stress condition can disturb poultry metabolism to change feed to be meat, especially for vitamin C synthesis can decrease even though poultry can synthesis vitamin C in its body. This research was done in Field Laboratory of Poultry Production Science, Faculty of Animal Science, Bogor Agricultural University at September 20 until November 22, 2002. Sixty mule ducks were used from four until 10 weeks of age in this research. This research used Completely Randomized Design that consists of three treatment levels of vitamin C supplementation (0, 500 and 1000 ppm) in basal diet. In every treatment levels consist of four replications and every replication consist of five heads mule duck. This research used broiler finisher commercial feed and used phannacologic vitamin C in powder fonn with minimum accuracy grade 98%.

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.
