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: Performance of KUB chicken that were given a zea mays subtitution as energy source of native chicken ration
Abstrak: Penelitian ini bertujuan menguji bahan pakan lokal sumber energi yang diperkaya sehingga memiliki komposisi nutrisi yang setara dengan jagung dalam ransum ayam kampung. Penelitian ini menggunakan 200 ekor DOC ayam KUB yang diberi pakan 4 perlakuan ransum yang memiliki sumber energi yang berbeda. Keempat Perlakuan tersebut terdiri dari: P0(ransum berbasis jagung), P1 (ransum berbasis gaplek), P2(ransum berbasis sorghum), dan P3(ransum berbasis batang pohon sagu). rancangan penelitian yang digunakan adalah rancangan acak lengkap (RAL) 4perlakuan dan 3 ulangan dengan masing masing ulangan terdiri dari 15 ekor. Peubah yang diamati meliputi konsumsi ransum, bobot badan, pertambahan bobot badan, konversi pakan dan mortalitas ayam. Data yang diperoleh dianalisis menggunakan anova dan uji jarak DUNCAN. Hasil penelitian menunjukkan bahwa pengaruh perlakuan subtitusi jagung berbasis gaplek, sorghum dan batang pohon sagu yang diperkaya dalam ransum ayam kampung tidak berpengaruh nyata (P<0,05) dibandingkan dengan ransum kontrol berbasis jagung terhadap performans ayam kampung umur satu sampai delapan minggu., This study aimed to test local feed ingredients as energy sources which were enriched so that they have a nutritional composition equivalent to corn for native chicken chicken rations. This study used 200 DOC native chickens which were fed with 4 ration treatments which had different energy sources. The four treatments consisted of: P0 (corn-based ration), P1 (cassava-based ration), P2 (sorghum-based ration), and P3 (sago stem-based ration). The research design used was a completely randomized design (CRD) with 4 treatments and 3 replications, each replication consisted of 15 chickens. The observed variables included feed consumption, final body weight, body weight gain, feed conversion and mortality. The data obtained were analyzed using ANOVA and the DUNCAN distance test. The results showed that the effect of treatment on cassava, sorghum and sago of the diet based on did not had any significant effect (P<0.05) compared to the diet based corn on the performance of native chickens aged 1-8 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.
