Judul: morfometrik ayam sentul, kampung dan kedu pada fase pertumbuhan dari umur 1-12 minggu
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: Ukuran Tubuh Ayam Kampung yang Diberi Pakan Dedak Padi dan Daun Singkong (Manihot esculenta Crantz)
Abstrak: This study aimed to know body size of native chicken with a fed mixture of rice bran and cassava leaf as long 12 weeks. Animals used native chicken as much as 45 males and 45 females. The feed is commercial feed (P1), a mixture of 75% rice bran and 25% cassava leaves as a substitute for commercial feed given from the age of 5-12 weeks (P2) and the age of 9-12 weeks (P3). These research used a randomized complete design (RCD) 2x3 factorial with 3 repetition. The first factor was sex (male and female). The second factor was the type of feed (P1, P2 and P3). Data was analyzed of variance (ANOVA). The variables measured were body weight, wing length, length of spine, sternum length, length of femur, tibia length, shank length, chest circumference and shank circumference. The results showed no interaction between sex with feed treatment toward of body size. Feed affected the morphometric of native chicken. Feed P2 given the lowest performance for all body size variables and impaired growth of native chicken when given from the age of 5-12 weeks. Feed rice bran mixture 75% and 25% cassava leaf can be given from the age of 8 weeks.

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.
