Abstrak: A total of 96 Sentul chickens aged 5 to 8 weeks consist of 48 males and 48 females were used in this experiment. These chickens were kept in litter in semi closed house. The experiment was factorial complete randomized designed with sex (male and female) and housing temperature (23 °C dan 30 °C) as factors. Physiological responses (rectal temperature and panting) as well as productive performances (feed consumption, body weight gain, feed conversion, and mortality) were measured. The results showed that housing temperatures significantly affected the rectal temperature and panting. Feed intake was significantly differed between male and female as well as body weight gain (P < 0.05) with males intake and gain more than female. Feed conversion differed significantly between housing temperatures (P < 0.01). No mortality was observed during experiment. The chicken reared under neutral temperature revelead better productivity than those under high housing tempeterature.

Judul: Respon Fisiologis dan Kinerja Ayam Sentul Umur 9-12 Minggu pada Kandang Bersuhu Netral dan Tinggi
Abstrak: Sentul chicken is one of Indonesian native chicken from district of Ciamis which produced eggs and meat. Temperature may influence the physiological response, performance, and behavior of sentul chicken. Sentul chickens consisted of 48 males and females each were placed into two different room temperatures, i.e., neutral and hot. Each house was devided into four pens for male and female. Each pen consisted of six chickenswhich were raised at 23 oC and 30 oC. Variables measured were feed consumption, body weight gain, feed conversion, and mortality. Rectal temperature and panting were measured. Data were subjected to analysis of variance and any differences were continued to Tukey test. The result showed that rectal temperature was significantly affected by house temperature. Performance of chickens at temperature 30 oC was the same with chickens at temperature 23 oC. Panting behavior was observed only in house with heat treatment. There was no mortality in both housing temperature.

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.
