Judul: Rancangan Kemasan Karton Bergelombang dengan Bahan Pengisi untuk Transportasi Jagung Semi (Baby corn)
Abstrak: Baby corn packaging usually use crate during transportation whereas it could make mechanical damages to the product like scratch, bruised, broke, and ripen rapidly. The purpose of this research was to design a proper packaging using carton material and filled material that could maintain the quality of baby corn during the transportation. In this research, C flute and BC flute, that has dimension (31x23x9)cm, (46.5x23.5x9)cm, (32x24x10)cm, (47.5x24.5x10)cm, were used as the outer packaging, B flute as inner, PE plastic as primary packaging, and pieces of paper as filling material. K4C and K6C were selected because those more adaptable in cold storage, those has good compression strength, and lower cost. Transportation conversion simulation result during two hours is similar to 169.553 km out of town length or 2.83 hours with 60 km/hour speed. Mechanical damage of the K4C is 17% meanwhile the K6C 15.9%, this is caused by the pieces of paper which used as the filling material around the product. The treatment of packaging directly influent to the parameter reduced of weight, hardness, and total dissolved solids of baby corn. On the other hand, the treatment of packaging indirectly influent the water content in the baby corn.

Judul: Perancangan Kemasan Transportasi Buah Jambu Air (Syzygium aqueum (Burm.f.) Alston) cv Camplong
Abstrak: Jamboo cv Camplong, called water rose, is one of the East Java’s superior fruits from Madura that have the high economic values and consumed as fresh fruit. It is including most perishable comodities and having short shelf life and also suspectible with impact and friction during transportation. Therefore the packaging technology during transportation becomes a critical point of post-harvest to maintain freshness of products when it is distributed to consumers. The purposes of this research were designing a secondary packaging during transportation and determining the appropriate type of primary packaging to maintain the quality of Jamboo. Materials in this reasearch were two types of corrugated cardboard (BC flute for packaging and A flute for partition) and jamboo cv camplong (weight 90 - 110 grams, diameter 60 mm and height 55 mm) from the Tadden village, Sampang East Java. The physical and mechanical properties of the fruits, and also the efficiency of the container space were being concerned to decide. The first step of packaging design. Secondary packaging design was done with determined dimensions, models, efficiency and manufacturing steps of packaging. The second step was done with tested of the package that has been designed, esspecially compression strength. For the third steps, the jamboo cv camplong was transported with net foam and paper packing filler (primer). After transportation process, fruits damage were observed visually and stored at room temperature ± 27 ºC. Then the color quality, hardness, total soluble solids, and amount of rotten fruits were observed every day during the time. Result of the packaging design (partitioned and unpartitioned) was having dimension 57x217x216 mm, with capacity of 45 pieces of fruits (equivalent to 4.5 kg) for partitioned packaging design and 69 pieces of fruits (equivalent to 7 kg) for unpartitioned packaging design. The strength of packaging resulted about 258.59 kgf (partitioned packaging design) and 401.92 kgf (unpartitioned packaging design) for pressure resist. Fruits that were packed with partitioned packing using net foam filler material had lowest mechanical damage (about 5.02 %), while the highest mechanical damage of fruits happened in the farmers packaging design (about 20.87 %) after transportation process. Statistical analysis showed that the influence of the primary packaging net foam / paper was significantly different, there are for color, hardness, total dissolved solids and total rotten fruits during storage after transportation. By using this designed packaging could give a net profit of about IDR 300.000 – 600.000 and it was greater than the conventional farmer’s packaging, by maximizing the container space during transportation.

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.
