Abstrak: Supplementation of Omega-3 in ration may enhance Omega-3 and lower the cholesterol contents in quail eggs. However, its impact to productive performances has not been clearly proved. This current experiment aimed to study the influence of Omega-3 supplementation in ration on productive performances of Japanese quail (Coturnix-coturnix japonica). This study was carried out for two months in the field laboratory of Poultry Production and Technology, Faculty of Animal Science, Bogor Agricultural University. This study involved 298 Japanese quail age 10 weeks and designed completely randomized in 5 treatments with 4 replications. The applied treatments were Omega-3 supplementation in the ration: P1 (control), P2 (1.5% Omega-3), P3 (3% Omega-3), P4 (4.5% Omega-3), and P5 (6% Omega-3). The observed traits were feed consumption, egg production, egg weight, feed conversion, mortality, and index of quail egg. All data were collected and descriptively analyzed. This study revealed no influence of Omega-3 supplementation to the production performance and index of quail egg.

Judul: Performa Produksi dan Kualitas Telur Puyuh (Coturnix-coturnix japonica) pada Kepadatan Kandang yang Berbeda
Abstrak: Stocking density is one of important environmental factor which is need to be considered in generating good production and quality of japanese quail (Coturnix-coturnix japonica) egg. This study was aimed to investigate the effects of various stocking density and determine the most optimum cage density on production and quality of quail egg. A total of 135 of japanese quails were used in this study. The quails were kept in cages with a stocking density of 12 birds, 15 birds, and 18 birds on 62 x 50 x 26 cm cages and each level of treatment consisted of 3 replications. Feed consumption, feed conversion ratio, hen day egg production, average egg weight, and mortality rate were recorded. Egg weight, shell weight, shell thickness, yolk colour, Haugh Unit (HU), and yolk index were also investigated. The obtained data were analyzed by using Analysis of Variance (ANOVA). Data of hen day production and feed conversion were presented descriptively. All traits were not different among treatments. The quails were kept in cages with a stocking density of 12 birds revealed the most optimum egg production according to the data of hen day production and feed conversion.

Judul: Penggunaan data spasial dalam struktur raster sebagai komponen sistem informasi geografi
Abstrak: Penggambaran peta dengan komputer merupakan penggambaran peta secara digital yang dikenal dengan nama pendigitasian. Data digitasi peta merupakan data masukan bagi Sistem Informasi Geografi (SIG). SIG merupakan sistem penanganan, dan pengelolaan data dan informasi geografi. Data yang menjadi bahan baku adalah data spasial atau data yang mengacu pada lokasi geografi. Dalam hal ini data dapat berasal dari peta dan data penginderaan jauh. Selain itu data masukan dapat pula berupa data non- spasial. Data ini dihubungkan dengan suatu atribut dari suatu legenda peta. Atribut dapat dicirikan oleh warna atau simbol yang artinya didefinisikan dalam legenda, sehingga pada SIG, data atribut nonspasial disimpan dalam bentuk yang dapat digunakan untuk analisis data. Struktur data spasial yang dipergunakan pada komputer adalah struktur vektor dan struktur raster. Struktur vektor menggambarkan titik, garis, dan poligon yang di- rangkai oleh koordinat-koordinat. Sedangkan struktur raster menyajikan nilai suatu sel kisi (grid cell) atau pixel yang dicatat dalam bentuk matriks. Masing-masing struktur tersebut dapat dikonversikan, yaitu struktur vektor dikonversikan menjadi struktur raster atau sebaliknya. Dengan demikian tidak ada perbe- daan sewaktu digunakan untuk analisis. ...
