Judul: Kebutuhan lisin ayam broiler yang diberi ransum dengan jagung sebagai biji - bijian utama
Abstrak: An experiment was conducted from December 3, 1982 to January 28, 1983 at Department of Animal Nutrition, Facul ty of Animal Science, Bogor Agriculture University. The main objectives of this experiment was to deter- mine the lysine requirement of broilers ration with corn as the major cereal grain on body weight gain, body weight at eight weeks of age, feed consumption, feed conversion, mortality, and income over feed and chick cost. The experimental material were used 180 day old male chicks of CP 707 strain. After wing banding the chicks were kept in wire boxes with wire floors of 1 X 1 X 0.5 m in measure. 3 The experimental design was Completely Randomized De- sign. There were four ration treatments and three repli- cation. In replication consist of 15 chicks. The four ra tions (R, RR, Re, and Ro) have been supplemented with 0, 0.4, 0.8, 8'and'1.5 nd' 1.2 percent lysine. The percentage of lysi- ne was based on 100 kg ration. Rations and water were pro vided ad libitum. After eight weeks of age, the average body weight ga- in was respectively 1 534.85 gram (R), 1 455.26 gram (Rg), 1 520.45 gram (R), and 1 514.97 gram (R); the average body weight at eight weeks was 1 586.86 gram (R), 1 505.05 gram (Rg), 1 559.54 gram (R), and 1 553.67 gram (R); the average feed consumption was 492.77 gram (RA), gram (R), 478.17 gram (R), and 474.62 gram (RA); 473.35 the ave rage feed conversion was 2.60 (RA), 2.63 (Rg), 2.51 (Rc), and 2.49 (Rp). Statistical analysis showed that there were no signifi cant effect of treatments on body weight gain, body weight at eight weeks of age, feed consumption, and feed conversi- on....

Judul: Persentase karkas, berat organ dalam dan lemak abdominal ayam broiler yang diberi konsentrat pakan lisin dalam ransumnya
Abstrak: Penelitian ini dilaksanakan di Laboratorium Nutrisi Unggas, Jurusan Ilmu Nutrisi dan Makanan Ternak, Fakultas Peternakan, Institut Pertanian Bogor, selama 6 minggu dari bulan Desember 1997 sampai bulan Januari 1998. Tujuan dari penelitian ini adalah untuk menguji apakah Konsentrat Pakan Lisin (KPL) bisa diberikan pada broiler serta memberikan pengaruh yang positif dengan melihat persentase karkas, berat organ dalam dan lemak abdominal. Materi penelitian terdiri atas 120 ekor anak ayam umur sehari (DOC) strain Starbro. Ransum penelitian disusun berdasarkan rekomendasi Scott et al. (1982) dan NRC (1994) dengan menggunakan KPL sebagai perlakuan. Ransum terdiri dari R1 (ransum dengan tepung ikan, tanpa KPL), R2 (ransum tanpa tepung ikan, mengandung KPL lisin), R3 (ransum tanpa tepung ikan, mengandung KPL kontrol) dan R4 (ransum tanpa tepung ikan, tanpa KPL). Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. Setiap ulangan terdiri dari 10 ekor anak ayam. Peubah yang diamati adalah persentase karkas, persentase berat hati, persentase berat ginjal, persentase berat jantung, persentase berat rempela, persentase berat limpa dan persentase lemak abdominal terhadap berat hidup. Pengaruh perlakuan terhadap peubah diukur dengan analisis sidik ragam (ANOVA). Sebelum dianalisis, data ditransformasikan ke dalam arcsin ✓ persentase. Hasil penelitian menunjukkan bahwa pemberian KPL dalam ransum broiler sebanyak 7% pada periode starter dan 10% pada periode finisher tidak berpengaruh nyata baik terhadap persentase karkas, persentase berat organ dalam maupun persentase lemak abdominal ayam broiler.

Judul: Pendekatan Baru untuk Verifikasi Integritas Peta Digital Berbasis Fitur Menggunakan Fragile Watermark
Abstrak: Watermarking can change the coordinates of features in map vector. Fragile watermarking technique is implemented to maintain the authenticity of the map and determine which features have been changed. Fragile watermarking technique was developed to giving watermark to each map feature. Quality testing was conducted by calculating the coordinates of each point of distortion due to watermark embedding, and the coordinates of each point are projected to calculate the shift in the real world. Testing the integrity of a map of the attack is done by comparing the value of the stored watermark and regenerated watermark. The attacks is done by manipulating the map by moving, adding and deleting map coordinates. This technique produces distortion on a scale of 10-4 and 10-7 meters distortion in the real world, so it is very difficult to detect visually to scale 1:1 map. This technique gives an additional coordinate for embedding watermark so consequently is berkas size be increased.
