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: Pengaruh Kemasan Terhadap Mutu Fisik Baby Corn (Zea mays L.) Selama Simulasi Transportasi
Abstrak: Distribution of baby corn from farmers to distributors in the market is generally transported using polyethylene plastic (25 kg/pack) with less consideration of its quality during the transportation. This condition causes baby corn often suffer from physical damages, such as broken and cracked. The purpose of this research was to study the influences of packaging materials on the mechanical damage and physical properties of baby corn during simulated transportation with addition of 8 days storage. Within this study, packaging materials chosen (considered as treatments) were: (i) combination between crates and polyethylene plastic, (ii) cardboard and polyethylene plastic, (iii) solely crates, and (iv) cardboard. Simulation was carried out at 2 hours transportation. The use of polyethylene plastic is capable of pressed the mechanical damage and reduced weight. The quantified physical parameters were mechanical damage, reduced weight, hardness, total dissolved solids and moisture content. Therefore, based on the reduced weight test and in combination with analysis of variance, the suitable packaging material for transporting baby corn was the one which combined from cardboard and polyethylene plastic.

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.
