Judul: Internal Quality of Hatching Egg from Different Age of KUB  (Kampung Unggul Balitbangtan Hen
Abstrak: Ayam KUB secara umum digunakan sebagai salah satu bibit ayam petelur penghasil Day Old Chicken (DOC) untuk memenuhi kebutuhan masyarakat terhadap daging dan telur di Indonesia. Kualitas internal telur tetas menjadi salah satu tolak ukur kualitas DOC yang akan dihasilkan, tujuan dari penelitian ini adalah mengkaji perbedaan karakteristik kualitas fisik internal telur tetas dari induk parent stock (PS) yang berumur 40 dan 60 minggu. Peubah yang diamati meliputi lebar rongga udara, berat yolk, indeks yolk, warna yolk, berat albumen, indeks albumen, dan haugh unit. Sampel yang digunakan berjumlah 30 butir telur dari masing- masing induk berumur 40 dan 60 minggu yang berasal dari pembibitan ayam Taman Teknologi Pertanian (TTP) Cigombong, Bogor, Jawa Barat. Penelitian ini menunjukkan adanya perbedaan nyata pada berat albumen, berat yolk, dan warna yolk. Tidak terdapat perbedaan pada nilai indeks yolk, nilai HU, indeks albumen, dan lebar rongga udara. Berat alumen, berat yolk, dan warna yolk telur tetas dari induk ayam umur 40 minggu memiliki nilai lebih tinggi dibandingkan dengan telur yang berasal dari induk ayam umur 60 minggu., KUB chickens is generally used as a breed of laying stock to produce Day Old Chicken (DOC) to fulfill the public requirement for local chicken meat and eggs in Indonesia. The internal quality of hatching eggs is one of the benchmarks for the quality of DOC, therefore this research was conducted to examine the internal quality characteristics of hatching eggs from the parent stock aged 40 and 60 weeks. Variables observed were included of the air cavity width, yolk weight, yolk index, yolk color, albumen weight, albumen index, and haugh units. There were 30 hatching eggs from each parent aged 40 weeks and 60 weeks produce by chicken breeding farm TTP Cigombong. The results showed significant differences in the albumen weight, yolk weight, and yolk color. There was no difference in the value of the yolk index, HU value, albumen index, and the width of the air cavity. The albumen weight, yolk weight, and yolk color hatching eggs from the parent stock aged 40 weeks were higher than from 60 weeks.

Judul: External Quality of Hatching Eggs of Ayam  Kampung Unggul Balitbangtan (KUB) from Different Hen Ages
Abstrak: Peningkatan umur ayam dapat menyebabkan warna kerabang telur semakin pudar, kerabang telur semakin tipis dan bobot telur semakin berat sehingga menurunkan kualitas telur yang dihasilkan. Tujuan penelitian adalah menganalisis perbedaan kualitas eksternal telur tetas ayam KUB dari induk parent stock (PS) yang berumur 40 dan 60 minggu yang berasal dari pembibitan ayam Taman Teknologi Pertanian (TTP), Cigombong, Bogor, Jawa Barat. Kualitas eksternal telur yang diamati meliputi bobot, bentuk telur, indeks bentuk telur, bobot kerabang, kebersihan kerabang, warna kerabang dan tebal kerabang telur. Jumlah telur yang diamati sebanyak 30 butir setiap kelompok umur. Data yang diperoleh dianalisis dengan statistik deskriptif yaitu pada kebersihan kerabang, bentuk telur, warna kerabang, dan kehalusan kerabang. Uji T (T-Test) independen digunakan untuk menganalisis data bobot telur, indeks bentuk telur, bobot kerabang dan ketebalan kerabang. Hasil penelitian menunjukan perbedaan yang nyata (P<0,05) pada bobot telur, indeks bentuk telur, bobot kerabang dan ketebalan kerabang. Penelitian ini menduga faktor lingkungan kandang, dan juga kesehatan ayam juga menentukan kualitas eksternal eksternal telur., The increasing of hen age may reduce the hatching egg color and shell thickness, and also increase the hatching egg weight. The aim of the study was to analyze the differences in the external quality of hatching eggs from 40 (P1) and 60 weeks of age (P2) of KUB chicken parent stock produced by chicken breeding farm TTP Cigombong, Bogor, West Java. The external hatching egg quality observed were included off the weight, egg shape, egg shape index, shell weight, shell cleanliness, shell color and egg shell thickness. There were 30 hatching eggs which were observed in this study for each age of group. The shell cleanliness, egg shape, shell color and shell smoothness were analyzed descriptively. The egg weight, egg shape index, shell weight and shell thickness was analyzed by T test (T-Test) independent. There were significantly differences (P< 0.05) in the egg weight, shell weight, and hatching egg shell thickness between hatching eggs produced by hens aged 40 (P1) and 60 weeks (P2). This study predicts that the environmental factor, and also chicken health might influence the external quality of chicken hatching egg.

Judul: Penyelesaian Numerik Persamaan Schrödinger untuk Molekul BaO dan SrO Menggunakan Model Potensial Morse
Abstrak: Morse potential is a potential model used to describe the behavior of a molecular vibration between atoms. This study aimed to obtain the value of the dissociation energy, the energy eigenvalues of each energy level, and describe the shape of the wave function of the molecule BaO and SrO on the vibrational state. Dissociation energy is calculated by adding the experimental dissociation energy and the ground state energy eigenvalues. Calculating the energy eigenvalues of the energy levels 0 to 4 using shooting method integrated with Numerov and Runge-Kutta method. Energy eigenvalues of each levels that calculated numerically having accuracy of 100% compared with the calculated analytically. The profil of wave functions accurately show the corresponding states and their normalized wavefunctions.
