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.

Judul: Sifat Pulp Campuran antara Pulp Asli Bambu dan Pulp Karton Bekas (Old Corrugated Containers)
Abstrak: OCC was soaked for 7 days and disintegrated afterward. Soda pulping of bamboo was carried out following the pulping parameters of 35% NaOH charge, L/W of 4/1, maximum temperature of 170 oC and total cooking time of 3 hours. Kappa number and pulping yield were determined based on TAPPI T236 cm-85 standard. Bamboo and OCC pulp was bleached following the method of D0ED1D2. Bleached bamboo pulp was beaten up to the freeness of 100, 200, 300, and 400 ml CSF. While that of OCC was up to 400 ml CSF only. The composisitions of bamboo/OCCpulp mixture (B/K) were 0/100, 20/80, 40/60, 60/40, 80/20 and 100/0. Physical and optical properties of pulp mixture were determined based on TAPPI T205 sp-02 standard. The pulp composition of (B/K) 20/80 at freeness level of 400 ml CSF was resulted in the highest strength properties based on Duncan scoring. Pulp beating was able to decrease the composition of bamboo pulp in pulp mixture while retaining the strength properties
