Judul: Performa Produksi Hasil Silangan Ayam IPB D2 dengan Ayam IPB D3 serta Resiprokalnya pada Umur 1 Sampai 12 Minggu di SHF
Abstrak: Persilangan antara ayam IPB D2 dengan ayam IPB D3 dan resiprokalnya dilakukan untuk menghasilkan keturunan dengan performa pertumbuhan yang baik. Penelitian ini bertujuan mengkaji performa produksi hasil persilangan antara ayam IPB D2 dengan ayam IPB D3 dan resiprokalnya. Penelitian dilakukan di peternakan Sinar Harapan Farm sebagai salah satu tempat pengembangan ayam IPB-D. Jumlah anak ayam hasil silangan IPB D2 x IPB D3 dan IPB D3 x IPB D2 masing-masing sebanyak 27 ekor dan 48 ekor. Pengambilan data dilakukan setiap minggu. Peubah yang diamati meliputi bobot badan, pertambahan bobot badan, konsumsi pakan, konversi pakan, dan mortalitas. Data yang diperoleh dianalisis deskriptif, selanjutnya dilakukan uji T. Hasil penelitian menunjukkan bobot badan jantan pada umur 12 minggu pada ayam IPB D2 x IPB D3 (1104,22 g) dan betina pada ayam IPB D3 x IPB D2 (975,55 g). Konsumsi pakan dan konversi pakan paling efisien ditunjukkan oleh ayam jantan dari silangan IPB D2 x IPB D3 dan ayam betina dari silangan IPB D3 x IPB D2. Kedua jenis ayam silangan ini memiliki performa baik dan berpotensi untuk dikembangkan sebagai ayam lokal pedaging di daerah pedesaan terutama di sekitar lingkungan SHF., Crosses between IPB D2 chickens and IPB D3 chickens were conducted to produce offspring with good growth performance. This study aimed to assess the production performance of the results of crosses between IPB D2 with IPB D3 and their reciprocals. The research was conducted at Sinar Harapan Farm as one of the IPB-D chicken development sites. The number of chicks from IPB D2 x IPB D3 and IPB D3 x IPB D2 crosses were 27 and 48 respectively. Data were collected every week. The observed variables included body weight, body weight gain, feed consumption, feed conversion, and mortality. The data obtained were analyzed descriptively, followed by T-Test. The results showed that body weight of males at the age of 12 weeks was owned by IPB D2 x IPB D3 chickens (1104,22 g) and females were owned by IPB D3 x IPB D2 chickens (975,55 g). The most efficient feed consumption and feed conversion were shown by IPB D2 x IPB D3 roosters and IPB D3 x IPB D2 hens. Both of these chickens have good performance and are potentially to be grown in rural areas, especially around the SHF neighborhood.

Judul: Body Morphometric of Candidate Line of IPB-D2 Chicken Fourth Generation Ages 2 to 12 Weeks
Abstrak: Ayam lokal Indonesia memiliki genetik yang tidak seragam, salah satu cara untuk meningkatkan produktivitasnya adalah dengan persilangan. Ayam lokal hasil persilangan dengan rumpun ayam pedaging yang dikembangkan oleh Institut Pertanian Bogor adalah ayam IPB-D1. Ayam IPB D-1 diseleksi berdasarkan immunocompletence membentuk calon galur ayam IPB-D2 (female line). Penelitian ini bertujuan mengkaji ukuran tubuh ayam calon galur ayam IPB-D2 generasi keempat umur 2 sampai 12 minggu. Jumlah ayam yang digunakan di Bogor sebanyak 75 ekor dan di Boyolali sebanyak 32 ekor pada umur 12 minggu. Peubah yang diukur yaitu panjang shank, lingkar shank, panjang tibia, panjang femur, panjang dada, lebar dada, dalam dada, lingkar dada, panjang punggung, panjang sayap, dan panjang leher. Data dianalisis secara deskriptif dan uji-t. Koefisien keragaman ayam IPB-D2 G4 berkisar antara 5,09% sampai 18,68%. Hasil menunjukkan ukuran tubuh jantan dan betina ayam IPB-D2 G4 cenderung tidak memiliki perbedaan yang nyata namun berbeda nyata dengan ayam IPB-D2 G4 di Boyolali baik pada jantan maupun betina. Ukuran tubuh ayam IPB-D2 G4 jantan dan betina sama. Kata kunci: ayam IPB-D2, morfometrik, persilangan, seleksi, Indonesian local chickens have non-uniform genetics, one way to increase their productivity is by crossing. The local chicken resulting from crossbreeding with the broiler developed by the Institut Pertanian Bogor is the IPB-D1 chicken. IPB D-1 chickens were selected based on their immunocompleteness to form IPB- D2 chicken line candidates (female line). The aim of this study was to examine the body size of the fourth generation of IPB-D2 at ages 2 to 12 weeks. The numbers of chickens used in Bogor were 75 birds and 32 birds in Boyolali at the age of 12 weeks. The variables measured were shank length, shank circumference, tibia length, femur length, chest length, chest width, chest, chest circumference, back length, wing length, and neck length. Data were analyzed by descriptive analysis and T test. The coefficient of diversity of IPB-D2 G4 chickens ranged from 5.09% to 18.68%. The results showed that the body sizes of the male and female IPB-D2 G4 chickens tended to have no significant difference, but were significantly different from the IPB-D2 G4 chickens at Boyolali both male or female. Morfometric of male dan female IPB-D2 G4 chicken were same. Keywords: crossing, IPB-D2 chicken, morphometrics, selection

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.
