Judul: Dinamika infeksi virus HIV dengan terapi Reserve Transciptase Inhibitor (RT Inhibitor)
Abstrak: Aequired immunodeficiency syndrom (AIDS) merupakan penyakit sistem kekebalan tubuh manusia. AIDS disebabkan oleh human immunodeficiency virus (HIV). Pada umumnya, virus HIV ditularkan melalui kontak langsung dengan cairan tubuh yang terinfeksi virus HIV, seperti transfusi darah atau seks bebas. Target utama dari virus HIV adalah sel darah putih. Sampai saat ini belum ditemukan obat atau vaksin, namun beberapa terapi dapat menahan laju penyakit. Terapi yang paling efektif adalah terapi antiretroviral. Terapi ini terdiri atas tiga jenis, yaitu reserve transciptase inhibitor (RT inhibitor), protease inhibitor, dan kombinasi keduanya. Tujuan dari karya ilmiah ini adalah menentukan pengaruh terapi reserve transciptase inhibitor terhadap dinamika infeksi virus dalam darah. Dinamika infeksi virus HIV ini dapat dilihat dalam beberapa model matematika. Pengaruh terapi RT inhibitor dapat dibedakan menjadi dua model, yaitu model terapi RT inhibitor sempurna dan model terapi RT inhibitor tidak sempurna. Kemudian, akan ditunjukkan dinamika infeksi virus HIV berdasarkan bilangan reproduksi dasar. Jika bilangan reproduksi dasar kurang dari satu, maka populasi sel virus akan hilang. Saat kondisi sebaliknya, jika bilangan reproduksi dasar lebih besar dari satu, maka populasi sel virus akan bertahan dalam tubuh.

Abstrak: Acquired immunodeficiency syndrom (AIDS) is a disease in the human system caused by the human immunodeficiency virus (HIV). In general, HIV virus is transmitted through direct contact with a body fluid containing HIV virus, such as blood transfusion or free sex. The major target of HIV virus infection is white blood cells. Although some therapies for AIDS can reduce the spreading of the disease, there is currently no vaccine or cure. The most effective therapy is antiretroviral therapy. Antiretoviral therapy consist of three therapies, i. e. reserve transcriptase inhibitor, protease inhibitor and a combination of both therapies. The objective of this paper is to determine the influence of reserve transcriptase inhibitor therapy to the dynamics of HI V virus infection in blood. This dynamics can be formulated in some mathematical models, i. e. the model of perfect RT inhibitor therapy and the model of imperfect RT inhibitor therapy. Furthermore, the dynamics of the virus infection can be shown in a basic reproduction number. If this number is less than one, then the virus population will be vanished. On the other hand, if it is larger than one, then the virus population will remain in blood.

Abstrak: Plastic basket packaging is still commonly used in the transport of mangosteen fruits, however plastic basket usage has a few disadvantages, such as random patterns composing which can cause mechanical damage to fruits, and plastic is also hard decomposite material, therefore it is needed alternative packaging to cover disadvantages of plastic basket packaging. This research with an entitled Design and Testing of Corrugated Fiber Board Packaging For Mangosteen (Garcinia mangostana L.) was done to design and test the packaging from corrugated fiber board and. The main material used for this research was the Mangosteen fruits and corrugated carton. There ware three stages of the research: designing packaging, testing the compressive strength, and optimization of the stack. Design process produced two packaging designs, that was: secondary packaging with capacity of 48 fruits per package (K48C dimensions 42.6 × 28.6 × 15.6 cm), and secondary packaging with 60 fruits (K60C dimensions 43 × 35.1 × 15.6 cm). Packaging materials used was type C flutes corrurugated fiber board for secondary packaging, and B flute for primary packaging, which K48C can be filled by 12 primary. While K60C can be charged 10 primary packages. Both designed packaging have a maximum stack of 25 piles. The results of transport simulation which was equivalent with 133.878 km in the road out of town or approximately 2:23 hours for truck with speed of 60 km/h shows level of fruits mechanical damage in K48C was 1.39%, while level of mechanical damage the fruit in K60C was 1.67%. Based on the test of variance and Duncan test show that the rate of change in weight, total dissolved solids, and hardness among fruits packed in selected packaging during transport simulation are not too different from control fruits. The result of optimization of selected package on the pallet ( 1200x1000x1500 mm) using Cube Master program shows that K48C packaging had efficiency of utilization value of pallet area of 80.66%, and 75.49% efficiency in volume usage. While for K60C, an efficiency utilization value of pallet area was 74.76%, and volume efficiecyt usage was 69.98%.
