Judul: Comparison of Non-Carcass Weight Percentage between IPB-D2 and IPB-D3 Chickens at Different Slaughter Age
Abstrak: Ayam lokal Indonesia merupakan komoditas yang banyak dipelihara oleh masyarakat untuk memenuhi kebutuhan ekonomi dan sumber protein hewani namun memiliki produktivitas yang sangat rendah. Ayam IPB-D1 merupakan rumpun baru ayam lokal yang telah dilakukan upaya peningkatan mutu genetik. Ayam IPB-D2 dan IPB-D3 yang merupakan keturunan ayam IPB-D1 yang diseleksi dengan tujuan menjadi calon galur baru dengan tingkat ketahanan tubuh yang baik serta pertumbuhan bobot badan yang cepat. Tujuan dari penelitian ini adalah menilai persentase bobot non karkas ayam jantan IPB-D2 dan IPB-D3 pada umur potong berbeda. Ayam yang digunakan adalah 100 ekor DOC IPB-D2 G3 dan 100 ekor DOC IPB-D3 G1. Penelitian dilakukan pada bulan September hingga Desember 2021 di Laboratorium Lapangan Pemuliaan dan Genetika Ternak, Fakultas Peternakan, Institut Pertanian Bogor. Peubah yang diamati adalah bobot kepala, ceker, usus total, hati, rempela, jantung, dan ginjal. Data yang diperoleh dianalisis dengan uji deskriptif dan uji t. Persentase bobot non karkas tertinggi ayam IPB-D2 G3 terdapat pada umur 12 minggu (24,26%) dan ayam IPB-D3 G1 pada umur11 minggu (25,78%)., Indonesian local chicken is the most widely kept by the community because it can meet the economic needs and source of animal protein but with very low productivity. IPB-D1 chickens are a new family of local chickens that have improved genetic quality. IPB-D2 and IPB-D3 chickens are descendants of IPB-D1 chickens that are selected to become candidates for new strains with a good level of body resistance and rapid bodyweight growth. This study purposes to assess the percentage of the non-carcass weight of IPB-D2 and IPB-D3 chickens at different slaughter ages. The chickens used were 100 DOC IPB-D2 G3 and 100 DOC IPB-D3 G1. The research was conducted from September to December 2021 at the Laboratory of Animal Breeding and Genetics Field, Faculty of Animal Husbandry, Bogor Agricultural University. The observed variables were head weight, claws, total intestine, liver, gizzard, heart, and kidney. The data obtained were analyzed by descriptive test and t-test. The highest percentage of the non-carcass weight of IPB-D2 G3 chickens was found at 12 weeks of age (24,26%) and IPB-D3 G1 chickens at 11 weeks of age (25,78%).

Judul: Carcass Percentage, Commercial Cuts, and  Non-Carcass Parts of IPB-D3 Chickens at Different Slaughter Ages and Locations
Abstrak: Ayam lokal memiliki ketahanan tubuh yang lebih tinggi dibandingkan dengan ayam ras. Ayam IPB-D3 merupakan calon galur baru pejantan (male line) yang dibentuk dari hasil seleksi ayam IPB-D1 G7 berdasarkan pertumbuhan bobot badan yang cepat pada umur 12 minggu. Pertumbuhan bobot badan yang cepat dapat dipengaruhi oleh genetik dan lingkungan. Penelitian ini bertujuan mengevaluasi persentase karkas, potongan karkas secara komersial dan bagian non karkas pada ayam IPB-D3 pada umur potong dan lokasi berbeda, yaitu Sukabumi, Bogor, dan Boyolali. Penelitian ini menggunakan ayam IPB-D3 Sukabumi sebagai data primer dan ayam IPB-D3 Bogor dan Boyolali sebagai data sekunder pembanding, masing-masing berjumlah 30 ekor. Berdasarkan hasil yang didapat adalah ayam IPB-D3 Sukabumi memiliki persentase karkas yang lebih rendah dibandingkan dengan ayam IPB-D3 Bogor dan Boyolali, akan tetapi bagian persentase non karkas ayam IPB-D3 Sukabumi lebih tinggi dibandingkan dengan ayam IPB-D3 Bogor dan Boyolali, Local chickens have higher immune resilience compared to commercial breeds. IPB-D3 chickens are a new male line strain created by selecting IPB-D1 G7 chickens based on their rapid body weight growth at 12 weeks. Tight body weight growth can be influenced by genetics and the environment. This research aims to evaluate the carcass percentage, commercially cut carcass pieces, and non-carcass parts of IPB-D3 chickens at different ages and locations, namely Sukabumi, Bogor, and Boyolali. The study utilizes IPB-D3 Sukabumi chickens as primary data and IPB-D3 Bogor and Boyolali chickens as secondary comparative data, with each group comprising 30 individuals. Based on the results, it is found that IPB-D3 Sukabumi chickens have a lower carcass percentage compared to IPB-D3 Bogor and Boyolali chickens. However, the percentage of non-carcass parts in IPB-D3 Sukabumi chickens is higher than in IPB-D3 Bogor and Boyolali chickens

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.
