Judul: Respon Lemak Abdominal dan Saluran Pencernaan Ayam Kampung dan Ayam Arab Terhadap Ransum Berserat Kasar Tinggi dengan Daun Katuk
Abstrak: Katuk with scientific name Sauropus adrogynus (L) Merr, is a part of the family of Euphorbiaceae. Native chicken is a local chicken from Indonesia which is the result of domestication from red jungle fowl (Gallus Gallus) and the green jungle fowl (Gallus varius). Arab Chicken are the descendants of Brakel Chicken Kriel-Silver from Belgium. The purpose of this research was to determined the effect of katuk leaf meal in the ration of the internal organs of Native Chicken and Arab Chicken. The research is conducted in Faculty of Animal Science, Bogor Agricultural University. There are two treatments, namely: P0 (using ration of katuk leaf meal for Native Chicken), P1 (using ration of katuk leaf meal for Arab Chicken). Each treatment consist of 3 replication, namely: U1, U2 and U3. Twenty heads of Native Chicken was 10 weeks of age (10 males and 10 females with 1 male and 1 female taken as the chicken’s control) and Arab Chicken’s too. To determine the effectiveness of the differences of using katuk leaf meal feeding rations between Native Chicken and Arab Chicken. Measured and observed variables are the abdominal and intenstinal fat, such as : duodenum, jejenum, ilium, caecum, colon. Analysis data using ANOVA and test of variance with Duncan test. The result of Duncan test showed that the abdominal and intenstinal fat, such as : duodenum, jejenum, ilium, caecum, colonhave different results on weight gain, length of organs and organ volumes were affected by the level of effectiveness of the absorption of the feed consumed.

Judul: Respon Ayam Arab (Gallus turcicus) dan Ayam Kampung (Gallus gallus domesticus) Terhadap Pemberian Tepung Daun Katuk (Sauropus androgynus) pada Ransum Berserat Kasar Tinggi
Abstrak: fowl feed-stuffs can be used to form ul ate diet for arab chicken native chicken. The utilizati on of a feed ingredient should consider some factors such as the quantity available, nutrient com positions, price and limiting factors such as anti-nutrient or toxins that exist in the feed ingredient. Some potential local feed ingredients that can be used for native chickens are rice bran, coconut meal, cpo, pollard and katuk leaf meal. The purpose of this research was to investigate the influence high crude fiber in the ration on performance of native chicken and arab chicken as feed consumption, body weight gain, feed conversion and cholesterol meat. Animal experiments with a total of eighteen native chicken and eighteen arab chicken 10 weeks of age respectively - each nine rooster and nine hens and four heads were given commercial feed as a comparison of chicken, using 4 threatments with 3 replicates, system maintenance battery cages and maintained until the 14th week. Treatment diet were formulated based on the level of use katuk leaf meal. The results showed that the provision of katuk leaf meal the arab male and female chickens better performance than the male and female native chicken on feed consumption, body weight gain, and feed conversion. Meat cholesterol shows arab chicken had lower cholesterol than native chicken.

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.
