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%.

Abstrak: Star fruit packaging commonly use fruit basket during transportation and stacked usually, whereas it could make mechanical damages to star fruit, like bruised, scratch, and broke on star fruit because it has soft texture. Therefore it needs more special treatment after harvest to reduce the damage during transportation and distribution. The purpose of this research is design a packaging for transportation and distribution on star fruit which the main material are star fruit and corrugated double flute. The steps of this research are designing packaging, compression strength testing and the spread of temperature in cold storage, selecting the packaging, and simulation of transportation. Design process produce four packaging design, that was: the first design with capacity of 24 fruits per package with circle ventilation (K24CV) and with oblong ventilation (K24OV) has dimensions 30 x 23 x 32 cm, then the second design with capacity of 40 fruits with circle ventilation (K40CV) and with oblong ventilation (K40OV) has dimensions 37 x 30 x 32 cm. The material of packaging design used BC flute for primary packaging (outer) and used B flute for secondary packaging (inner). K40CV was a selected packaging based on the testing during research when has average ability to resist compression about 272.32 kgf and more adaptable in cold storage than other packaging design when enter the minute of 130 it has a stable which the different temperature from each other point in the packaging is about 0.15-0.4ºC

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.
