Judul: Studi Penataan Taman Dalam Ruang Hotel-Hotel Di Jakarta
Abstrak: Studi ini dilakukan untuk mempelajari dan mengevaluasi penataan taman dalam ruang di hotel-hotel berbintang lima yang telah dilaksanakan di Jakarta pada bulan April-Oktoher 2002. Metode penelitian yang digunakan adalah metode survai dengan teknik wawancara. pengamatan langsung, penyebaran kuesioner dan studi pustaka. Survai dilakukan terhadap letak taman dalam ruang, kondisi fisik mang, pemilihan jenis tanaman, konsep perencanaan dan perancangan, penerapan prinsip disain pada elemen disain, persepsi pengguna terhadap taman dan penataan taman dalam ruang hotel.

Judul: Evaluasi Fungsi Ekologis Dan Estetika Pada Beberapa Taman Kota Di Jakarta Selatan
Abstrak: Taman kota sebagai salah satu jenis ruang terbuka hijau publik yang memiliki peran penting dalam meningkatkan kualitas lingkungan perkotaan. Dua aspek penting yang perlu dalam taman kota yaitu fungsi ekologis dan estetika. Untuk mengetahui sejauh mana pelaksanaan fungsi ekologis dan estetika, perlu adanya evaluasi menyeluruh dari aspek tersebut. Penelitian ini bertujuan untuk mengidentifikasi vegetasi, mengevaluasi pelaksanaan fungsi ekologis dan estetika, dan untuk mengetahui persepsi serta preferensi pengguna dari lanskap di setiap taman. Penelitian dilaksanakan selama tujuh bulan dan berlokasi di empat taman di Jakarta Selatan, antara lain Taman Ayodya, Taman Martha Tiahahu, Taman Tangkuban Perahu dan Taman Mataram. Metode penelitian ini dibagi menjadi dua metode, evaluasi fungsi ekologis dan evaluasi kualitas estetika di setiap taman. Fungsi ekologis akan dievaluasi dengan membandingkan kondisi yang ada dengan kriteria standar untuk fungsi ekologis, sedangkan kualitas estetika akan dievaluasi dengan menggunakan metode scenic beauty estimation (SBE) serta preferensi pengguna dan persepsi. Hasil penilaian fungsi ekologis, Taman Tangkuban Perahu terbaik dalam fungsi peredam bising dan penahan angin, Taman Ayodya terbaik dalam modifikasi suhu dan Taman Martha Tiahahu terbaik dalam fungsi kontrol kelembaban. Penilaian estetika, Taman Ayodya memiliki kualitas estetika tertinggi dan Taman Tangkuban Perahu memiliki kualitas terendah. Kondisi ekologis yang baik berpengaruh terhadap kondisi estetika taman.

Judul: Kloning dan Ekspresi Human Interferon-alfa2a pada Yeast Metilotropik Pichia pastoris
Abstrak: Interferon (IFN) is a group of proteins that are secreted by body cells as a result of exposure to biological vertebrates such as: viruses, bacteria, protozoa and other compounds. There are three types of interferon, namely: alpha (α), beta (β) and gamma (γ) IFN. Interferon-α2a belongs to the type I interferon. This protein has a molecular weight of 21.550 kDa and consists of 188 amino acids (23 amino acid of signal peptide and 166 amino acids of mature protein). Interferon-α2a is also known to be used for the treatment of hepatitis C and as anti-tumor and antivirus agents. Regulator gene for IFN production under normal conditions, is in the off position to IFN is not produced. But when there are external stimuli, both viral and bacterial infections, a regulator gene switches on, and IFN production system running. At the time of an attack from a variety of disease agents actually the body will produce IFN, but generally the amount produced is not sufficient to fight the disease agents that multiply very quickly. Therefore IFN intake from outside is needed. This is the beginning of the use of IFN as a drug. Genetic engineering is an activity to manipulate the genes to get new products by creating recombinant DNA through gene insertion. Recombinant DNA technology has been used to produce IFN. Yeast such as Pichia pastoris can be an alternative as the host (system) to express human interferon genes and as a producer of IFN protein. Expression system P. pastoris offers several advantages for the production of recombinant proteins, such as: the high level expression of recombinant proteins, ease of scaling-up fermenter, low cost and ease of transformation techniques and selection of transformed cells such as bacteria . The existence of inducible AOX1 promoter is very strong, easily control the expression of recombinant proteins by induction. AOX1 is a promoter that controls gene expression of alcohol oxidase to metabolize methanol as carbon source of P. pastoris. Therefore,this study aimed to clone human interefron-α2a (hifnα2a) gene in E. coli and express it in metylotrophic yeast P. pastoris. Vector used in this study is pPICZαB (Invitrogen). Ligation process between insert (hifn-α2a gene) and vector (pPICZαB) performed by using T4 DNA ligase, which functions synthesize the formation of phosphodiester bonds linking the nucleotides with nucleotide insert plasmid vectors to produce recombinant (pPICZαB-hifnα2a). This recombinant plasmid transformed into XL1 blue cells (E. coli) by Heat shock method. The results of sequencing analysis (clone 6) using 5'AOX and 3'AOX primers indicate that DNA base sequence of human IFN-α2a genes has been subclone into pPICZαB vector (in frame). Recombinant plasmid (clone 6) linearized using BstX1 enzyme before transformed into X33 yeast cell. Transformation into cell was done by Electroporation. The X33 cell P. pastoris strain was used to express human interferon-α2a. X33 is strains with the phenotype Mut+ (methanol utilization plus) and can be used for positive transformants selection using zeocin. Phase protein production work using Mut+ strain occurred in two phases. The first phase is the use of glycerol to obtain a certain amount of biomass (high cell
