Judul: Karakteristik Fisik Wol Domba Batur dan Domba Garut
Abstrak: Batur sheep produce medium wool, while garut sheep produce coarse wool. Knowledge about wool physical characteristics of both breeds are important due to the potential background for utilization to certain product. The aims of this research were to indentify and compare wool physical characteristics of batur sheep (WB) and garut sheep (WG). The variables observed including bundle tenacity, elongation, flammability, sound and thermal insulation properties. The comparison data of sound and thermal insulation ability between board (P), board + batur sheep wool (PWB), and board + garut sheep wool (PWG) were designed by Completely randomized design (CRD) and analyzed by Analysis of Variance (ANOVA) as well as the comparison data of flammability between WB, WG, P and nylon. The other data were analyzed by T-test. The result showed that WB and WG had no significant difference on their tenacity, resilient, and flammability (P > 0.05). PWB and PWG had better sound and thermal insulation ability more than P. Wol had flammability better than P and nylon

Judul: Laju Pertumbuhan dan Kualitas Wol Domba Batur dan Domba Garut
Abstrak: Batur sheep and garut sheep have good potential of their wool utilization because both types of sheep are crossbreed between local sheep with merino sheep. Research about wool quality of local sheep is still very limited. Information about growth rate and quality of wool would be useful as a reference for the utilization and processing of wool. Parameters observed in this research consist of growth rate, staple length, fibre diametre, staple strength, and staple elongation. Wool sample taken from midside body of sheep. This experiment was conducted on a sheep farm in Garut and Banjarnegara and Physical Evaluation Laboratory, Higher School of Textille Technology Bandung. Data were analyzed using T-Test method with 2 independent samples with five replicates of each samples and the data then was processed using Minitab 16. The analysis showed significant difference in the parameters of length, diameter and fibre growth rate. Conversely, breed factor had no significantly differences to staple strength and staple elongation. Batur sheep has a characteristic and wool’s quality better than garut sheep, so that batur sheep has a more chance to develop as a wools producer

Judul: The Dynamic of HIV Virus Infection as a Result of Protease Inhibitor Therapy.
Abstrak: Acquired immunodeficiency syndrome (AIDS) is defined as symptoms of deterioration human immune system caused by human immunodeficiency virus (HIV). The virus damages the leucocytes; therefore, once a person infected by the HIV, his/her immune system will be paralyzed and eventually will not be able to survive from any disease. HIV is transmitted in many ways, such as having unsafe sex, using unsterilized syringe, blood transfusion, and many more. So far, there has not been discovered yet a way or a medicine that can totally cure this disease. However, reverse transcriptase inhibitor therapy, protease inhibitor, or combination of those two can decline the growth of virus inside the body of the infected person. Therefore, the immune system will be enhanced back to normal phase. In this paper, will analyze the effect of protease inhibitor therapy on the dynamics of virus inside the blood with different value of effectiveness. There are two mathematical models of protease inhibitor therapy to consider, i.e. perfect and imperfect protease inhibitor. The perfect protease inhibitor therapy hinders the virus to grow well and not to infect healthy leucocytes. On the other hand, the imperfect one cannot completely detained the virus growth.
