Judul: Keragaan Karakter Agronomi Beberapa Varietas Jagung (Zea mays L.) Dalam Produksi Jagung Semi
Abstrak: Research was conducted to studied agronomic characters some varieties of maize in baby corn production. In addition, to determinated the varieties that are relatively equal or better than the control. The varieties were consisted of local varieties (Campaloga 2009, Ketip Kuning 2117, Lokal Oesao 3033, and Lokal Srimanganti 3201), introduced varieties (EW DMR Pool C6S2 3325 dan Phil DMR Comp. 2 3423), results of breeding variety (Arjuna 2585), and one of variety hybrid, BISI 2 as a comparison. The researh arranged in a split plot randomized completely block design with two factors and three replications. Character that was had greatest influence in determining the net weight cob of plant/yield were the net weight of cob, number cobs of plant, gross weight cobs of plant, number of rejects cob, cob length, and diameter of cob. Interaction variety and detasseling had significant respons to gross weight of cob for two varieties. They were Lokal Srimanganti 3201 and Arjuna 2585. The results showed that Arjuna 2585 has yield more than BISI 2. Varieties that had the potential of yield characters were Arjuna 2585, Lokal Srimanganti 3201, and Lokal Oesao 3033. In this research, generally detasseling increasing the yield and quality of baby corn.

Judul: Analisis Potensi Hasil Dan Kualitas Hasil  Beberapa Varietas Jagung (Zea mays L.) Sebagai  Jagung Semi (Baby Corn)
Abstrak: Penelitian ini bertujuan untuk memperoleh informasi potensi beberapa varietas jagung yang dapat dimanfaatkan untuk memproduksi jagung semi (baby corn). Penelitian ini dilaksanakan di Kebun Percobaan Leuwikopo IPB, Darmaga, Bogor pada bulan Mei sampai dengan Juli 2009. Penelitian ini menggunakan Rancangan Kelompok Lengkap Teracak dengan genotipe sebagai perlakuan. Genotipe ini terdiri dari 17 genotipe koleksi dari Balai Besar Penelitian dan Pengembangan Bioteknologi dan Sumber Daya Genetik Pertanian (BB Biogen) terdiri atas 5 genotipe lokal (Campaloga, Genjah Kodok, Ketip Kuning, Lokal Oesao, Lokal Srimanganti), 7 genotipe hasil pemuliaan (Antasena, Arjuna P18, Bayu, BC 10 MS 15, Nakula, Sadewa, Wisanggeni), dan 5 genotipe introduksi (EW DMR Pool C6S2, EY Pool C4S2, Kiran, Phil DMR Comp. 2, Phil DMR 6) serta varietas hibrida BISI-2 sebagai pembanding. Pengulangan dilakukan sebanyak tiga kali sehingga seluruhnya terdapat 54 satuan percobaan. Terhadap data tiap peubah dilakukan analisis ragam. Uji nilai tengah yang digunakan adalah t-Dunnett untuk membandingkan tiap genotipe yang diuji dengan hibrida BISI-2 sebagai pembanding serta uji kontras ortogonal untuk membandingkan genotipe atau kelompok genotipe yang dikehendaki.

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.
