Judul: Performa Domba Kembar Lepas Sapih yang Mendapat Kobalt dan Konsorsium Bakteri Rumen selama Periode Prasapih
Abstrak: In the period of weaning, twin born lambs with low birth weight are more susceptible to environmental temperature and pathogenic infection. This study was design to evaluate the performance of weaned twin lambs offered diet supplemented with Co and rumen bacteria consortium during pre-weaning period. Eight of three months-old of twin garut lambs were selected for this study. Data were analyzed according to t-test student. Treatments consisted of: 1). Control diet and 2) diets supplemented with Co + rumen bacteria consortium (CoBac) during pre-weaning period. Result showed that as feed and dry matter intake of post-weaning twin lambs significant (P<0.01) to gain with equation was y = -583.4 + 92.83x; r2 = 0.77 and y = -244.5 + 47.85x; r² = 0.67. The gain (P<0.01) accord with age of post-weaning twin lambs with y = 0.056x + 5.788; r² = 0.352. There were no significant in nutrient intake, digested nutrient and average daily gain of post-weaning twin lambs. Supplemented Co + rumen bacteria consortium could not improved performance of post-weaning twin garut lambs.

Judul: Performa, absorpsi dan profil mineral darah domba kembar lepas sapih yang mendapat kobalt dan bakteri rumen selama prasapih
Abstrak: Periode transisi pasca sapih merupakan periode kritis; mikroba rumen anak domba belum berkembang, pemberian susu dihentikan dan pemberian pakan diubah dari pakan yang mudah dicerna ke pakan yang sulit dicerna. Namun performa anak domba dan perkembangan bakteri rumennya selama prasapih dapat mempengaruhi utilisasi nutrien dan performanya pada periode transisi lepas sapih. Penelitian ini bertujuan untuk mengevaluasi performa, absorpsi dan profil mineral di darah (Ca, P, dan Mg) pada anak domba lepas sapih yang diberi Co dan konsorsium bakteri rumen selama periode prasapih. Sebanyak 8 ekor domba garut umur 3-4 bulan dengan kisaran bobot badan 9.86±2.02 kg digunakan dalam penelitian yang sudah dibagi ke dalam dua perlakuan yaitu kontrol dan pasca pemberian konsorsium bakteri rumen selama periode prasapih (CoBac) dan dikelompokkan menjadi empat kelompok berdasarkan bobot badan. Hasil menunjukkan bahwa pemberian Co dan konsorsium bakteri rumen selama periode prasapih belum dapat mempengaruhi performa, absorpsi mineral dan profil mineral darah domba saat lepas sapih.

Judul: Penerapan teknik watermarking untuk penandaan hak cipta pada peta vektor dengan format DXF
Abstrak: Drawing Interchange Format (DXF) is one of the general file in the field of the vector image commonly used for making maps. The DXF format is a tagged data representation of all the information contained in an AutoCAD drawing (DWG) file. Tagged data means that each data element in the watermark is preceded by an integer number called the group code. The study was carried out because there is still no tools of labeling the copyright on digital mapping using DXF file. This study aims to generate an application for copyright labeling on vector map with DXF format that can be applied to any types of spatial objects in the map. The technique used is changing the code inside the vector image. The insertion of the watermark is done by utilizing ENTITIES section by multiplying objects for sets of binary values. The results showed that the image after the watermarking insertion process is the same as the original vector image. Embedded watermark is resistant to rotation and scaling, however it has the possibility of one-third to be broken in the attack on specific object. This study has successfully implemented watermarking technique for copyright labeling on the vector map with DXF format.
