Judul: Kualitas Telur Tetas dan Perkembangan Somite (Tulang Belakang) pada Embrio Ayam Arab dari Umur Induk yang Berbeda
Abstrak: Arab chicken is one of the most favorite local layer chicken developed in Indonesia due to their high productivities. The egg qualities are highly influenced by the hen age. Somitogenesis is an early step in chick embryo development. The data of somite development on chick embryo is very limited, especially in Arab chicken. Therefore this research aimed to analyze the influence of hen breeder age on formation of somites. There were 99 eggs from 36, 42, and 54 weeks of hen age will be used in this study. The embryo samples were harvested in 24, 33, and 48 hours after incubation. The Complete Randomized Design was used to analyze exterior and interior of egg qualities such as the egg weight, egg shape index, shell weight and shell thickness. The number of somites will be analyzed descriptively. The results show that hen age had effect significantly the egg weight and the shell thickness (P<0,05). Hen age did not affect the egg shape index and the shell weight (P>0,05). There were died embryos from hen age of 54 weeks (22%) and 42 weeks (15,38%). The embryo from 42 week of hen age developed slower (15,38%) than embryo from 36 and 54 weeks.

Judul: Karakteristik Kualitas Telur Tetas dan Perkembangan Tulang Belakang (Somite) Embrio Ayam Arab pada Umur Telur yang Berbeda
Abstrak: Umur telur merupakan salah satu faktor yang dapat mempengaruhi kualitas telur tetas yang digunakan dalam penetasan. Penyimpanan telur yang semakin lama akan menurunkan kualitas telur. Kualitas telur tetas meliputi kualitas eksterior dan interior, faktor ini dapat mempengaruhi perkembangan embrio di dalam telur. Perkembangan embrio meliputi pembentukan tulang belakang (somite). Sampai saat ini data tentang perkembangan somite pada ayam lokal terutama ayam Arab masih terbatas, sehingga diperlukan penelitian mengenai pengaruh umur telur terhadap perkembangan somite pada ayam lokal (ayam Arab). Tujuan penelitian ini adalah untuk mengetahui karakteristik telur tetas dan perkembangan tulang belakang (somite) embrio ayam Arab pada umur telur yang berbeda. Penelitian ini juga bertujuan untuk memberikan informasi mengenai umur telur tetas yang sebaiknya digunakan dalam penetasan.

Judul: Pelabelan Super Vertex Magic
Abstrak: Super vertex magic labeling is labeling on graph with is a set of edges mapped into and is a set of vertices mapped into . It has a vertex magic labeling in which and represents the size and order of the graph respectively. This manuscript proves that paths, cyclics, and disjoint union of cyclics have a super vertex magic labeling. There are four theorems to be discussed. The first theorem proves that path is super vertex magic if and only if is odd and . The second theorem proves that cyclic is super vertex magic if and only if is odd. The third theorem proves that bijection function from an edge set onto of graph can be extended to a super vertex magic labeling if and only if the set amount of edge label that incidents with a vertex in the graph, consists of sequential integers as many as vertices in the graph. The fourth theorem proves that disjoint union of the cyclics consists of cyclics with each cyclic has vertices is super vertex magic if and only if and are odd.
