Abstrak: The purpose of this research is to complement the morphometric data of local chiken such as native chickens, Sentul and Kedu on the growth phase of 1-12 weeks of age. As well as body size that can be used to estimate the weight. Animals used in this study is the local chicken consists of three types of native chickens is 25 Kampung, 25 Sentul and 25 Kedu. The design used in this study is to RAL and RAL factorial pattern, beside that the data were analyzed by correlation analysis and multiple regression. The variables measured were body weight, shank length, beak length, chest width, length back, and chest circumference. ANOVA results showed that the average weight Sentul chickens, Kampung chickens and Kedu checken age of 5-12 weeks were not significantly (P<0.05). Results of variance analisys showed that the length of shank of Sentul chicken, Kampung and Kedu on age of 5-12 weeks were not significantly, but between male and female chickens have a shank length growth were significantly (P <0.01). On 8-12 weeks old chicken, the results of variance showed highly significant differences between Sentul chickens, Kampung and Kedu. On the age of 1-4 weeks of Kampung chickens had the highest determination coefficient value compared with chicken Sentul and Kedu that was equal to 54.7% regression equation was Y = - 569 + 6.84 PS - PPrh + 7.97 5.26 PP + 27. 5-LED. On the age of 5-12 weeks male Sentul chickens had the highest determination coefficient value compared with native chickens and Kedu, amounting to 99.9%. Multiple regression equation at the male Sentul chicken was Y = - 381 + 13.1 PS + 0.32 PPrh + 7.30 LD + 29.1 PP - 38.2 LED.

Judul: Performa F1 antara Ayam Sentul X Kampung dan Ayam Pelung X Sentul pada Umur 0-12 Minggu
Abstrak: The experiment aimed to observe growth performance of 3 native chicken crossed. The materials used in this experiment were 22 day old chick (DOC) resulted of natural mating between male pelung and female sentul chicken (PS) and 113 DOC resulted of natural mating between male sentul and female kampung chicken (SK). Feeds were given during experiment divided into 3 phases that were BR-21E 100% for chicken between 0-3 weeks of age, rice bran 20% and BR-21E 80% for 4 week age, and grower feeds rice bran 40% and BR-21E 60% for chicken between 5-12 weeks. Variables which recorded weekly were body weight until 12 weeks of age, weight gain, feed consumption, feed conversion, and mortality. The t-test was used to compare data of performance between two sexes and between two cross system (PS and SK). The results showed that body weight at 12 weeks of crossbred (PS) male was significantly higher than SK (P<0.01) also female (P>0.05). Feed consumption and feed conversion were not significantly different (P>0.05). The mortality rate during the experiment were 4.54% for crossbred PS and 7.07% for SK. SK and PS can be applied to increase meat production.

Judul: Pembuatan Film Tipis Lithium Niobat (LiNbO3) Menggunakan Metode Chemical Solution Deposition (CSD) dengan Variasi Kecepatan Putar (Rpm).
Abstrak: Film tipis merupakan salah satu aspek yang mendapat perhatian sangat besar dalam bidang material, karena film tipis merupakan material menarik yang memiliki sifat optik yang sangat tergantung pada konstanta dielektrik, indeks bias, dan energi gap. Lithium Niobat (LiNbO3 ) dapat digunakan sebagai pelapis pada film tipis karena memiliki sifat piezoelektrik, electrooptical, pyroelectrical dan photorefractive yang sangat baik. Film tipis Lithium Niobat (LiNbO3 ) ditumbuhkan menggunakan metode Chemical Solution Deposition (CSD) dengan variasi kecepatan 3500 rpm, 5000 rpm, 6500 rpm, dan 8000 rpm. Metode ini memiliki keunggulan dapat mengontrol stokiometri film tipis dengan kualitas yang baik, prosedur yang mudah dan membutukan biaya yang relatif murah. Energi band gap yang dihasilkan dari film tipis Lithium Niobat (LiNbO3) berkisar antara rentang 2.1 eV – 2.8 eV dengan indeks bias berada pada rentang 2.18-3.2. Film tipis LiNbO3 memiliki parameter kisi a=b=5.54Ǻ dan c = 16.35 Ǻ. Struktur morfologi film tipis adalah permukaan yang homogen dan ukuran kristal berada pada rentang 0.417 μm – 0.680 μm.
