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: The transition period at post-weaning is a crucial period; the microbial rumen of lamb is not developed yet, milk diet has been removed and the feeding regime is changed. However, growth performance and rumen bacteria in preweaning period affects the growth and nutrient utilization of weaned lamb. The study was designed to evaluate the performance, the absorption and the blood mineral profile (Ca, P, and Mg) in post-weaning lamb offered Co and rumen bacteria consortium previously in the pre-weaning period. Three-four months old of 8 garut sheep with initial body of 9.86±2.02 kg were divided into two treatments groups of control and the post administration of rumen bacteria consortium (CoBac) groups. Results showed that administration of Co and rumen bacteria consortium during pre-weaning period had no effect on performance, mineral absorption and blood mineral profile in post-weaning. It is concluded that administration of Co and rumen bacteria consortium during pre-weaning period of lamb did not improve the performance and nutrient utilization during transition period.

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.
