Judul: Kandungan Beta Karoten  dan Nilai Gizi Telur Asin dari Itik yang Mendapat Pakan Limbah Udang
Abstrak: Egg was animal food product which has excelent nutrient. Duck egg nutrition composition was influenced by feed consumed. Shrimp waste could be used as feed for duck because it has good nutrient composition and cheaper compared to fish flour. Egg preservation by salted that allowed penetration salt solution could change nutrition composition in the egg. Duck egg was used as raw material for salted egg processing because it has big pore at the shell allow then to absorb water and suitable for produce salted egg. The aim of this research was to study the effect of feeding duck by shrimp waste and preservation of egg by brinning salted pickled on nutrition and beta caroten of the salted egg. The variable determinant were values of water, ash, protein, fiber, fat, calsium, and beta carotene contained in the eggs. The data were analyzed by variance showed that shrimp waste influenced values of ash, protein, fiber, fat, and calsium. Egg salted processing influenced values of water, ash, protein, fiber, and fat. Shrimp waste in feed resulted yolk has orange colour.

Judul: Karakteristik Kimia dan Mikrobiologi serta Organoleptik Telur Asin dengan Lama Pengovenan yang Berbeda Selama Penyimpanan
Abstrak: Duck egg is one of poultry products which often be made as salted egg. Nowdays, salted egg can be cooked by different methods, one of them was oven baking method. This main research was aimed to study chemical, microbiology, and organoleptic characteristics of salted duck egg produced by different oven baking time during storage. Salted duck eggs were baked for a duration of four and six hours after boiling (R+O4 and R+O6). Chemical and microbiology characteristics were determined at 0, 15, and 30 days, while organoleptic characteristics were determined at 7 and 28 days. Completely Randomized Design with 3 treatments (boiling (R), R+O4, R+O6) and 3 replications for chemical characteristics or 2 replications for microbiology characteristics was used in this experiment. Data from chemical and microbiology test was analyzed by analysis of variance, while data from organoleptic test was analyzed by Friedman and Kruskal Wallis. The results showed that there were significant differences (P<0.05) in water content of albumen and total plate count of whole egg before storage (0 day), and after storage (7 and 28 days) there were significant differences (P<0.05) in organoleptic characteristics. In conclusion, salted eggs that were oven baked for six hours were the best in this research.

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.
