Judul: Visual Condition Assessment of the Traditional House of Gadang Mandailing in North Sumatra
Abstrak: Rumah Tradisional Gadang Mandailing merupakan warisan budaya Indonesia yang unik. Rumah Gadang, Rumah Ayu, dan Rumah SD tersusun dari komponen utama kayu. Kayu yang digunakan pada setiap bangunan adalah kayu meranti (Shorea sp.). Identifikasi visual bangunan meliputi pondasi/lantai, dinding, pintu dan jendela, kolom dan atap. Identifikasi meliputi jenis kerusakan dan organisme perusak yang menyerang pada setiap komponen. Hasil identifikasi visual keandalan tiga bangunan rumah adat, yaitu Rumah Gadang 60 %, Rumah Ayu 75%, dan Rumah SD 58%, berdasarkan predikatnya Rumah Gadang dan Rumah SD masuk dalam ketegori Rusak Ringan dimana kedua bangunan mengalami kerusakan umumnya pada bagian non struktural dan Rumah Ayu masuk dalam kategori sedang dimana bangunan masih berfungsi tanpa adanya pemeliharaan rutin. Nilai kadar air rata-rata yang diperoleh pada kayu meranti (Shorea sp.) adalah 11,03%, 11,42%, 12,47 %. Berat Jenis 0,62 g/ cm3, 0,75g/ cm3, 0,75g/ cm3 dan kerapatan 0,69 g/ cm3, 0,84 g/ cm3, 0,85 g/ cm3. Organisme perusak yang ditemui setelah dilakukan pengamatan secara visual berupa serangga jenis Trigona sp., The traditional house of Gadang Mandailing is a distinctive Indonesian cultural heritage. Rumah Gadang, Rumah Ayu, and Rumah SD are constructed of wood as the main component. The wood used in each building is meranti (Shorea sp.). The wood visual condition assessment was conducted through observation on the foundation/floor, walls, doors and windows, columns and roofs. The assessment of the building reliability was analysed on the traditional house buildings, namely Gadang House 60%, Ayu House 75%, and SD House 58%. According to the level of damage, Gadang House and SD House are in Minor Damage Level category, where the two buildings underwent damage in non-structural parts. Meanwhile, Ayu House is in Medium Damage Level, where it is still functioning without routine maintenance. The average moisture content value obtained for each type of wood is 11,03%, 11,42%, 12,47 %. Specific gravity 0,62 g/ cm3, 0,75 g/ cm3, 0,75 g/ cm3 dan density 0,69 g/ cm3, 0,84 g/ cm3, 0.85 g/ cm3. Destructive organisms encountered after visual observation were insects of the Trigona sp.

Judul: Evaluasi Kondisi Rumah Adat Sumatera Selatan dan Sulawesi Utara di Taman Mini Indonesia Indah.
Abstrak: Rumah adat adalah Rumah tradisional yang menilaikan warisan budaya di Indonesia. Rumah adat Limas Sumatera Selatan dan rumah adat Pewaris Sulawesi utara yang komponen bangunan dari kayu dan beton. Hasil penilaian indeks kondisi bangunan menunjukkan nilai kekokohan masing-masing rumah adat Sumatera Selatan dan Sulawesi Utara secara berturut-turut sebesar 73% dan 68.85%. Nilai tersebut menunjukkan kedua bangunan masih berfungsi baik namun belum adanya perawatan dan pemeliharaan terhadap bangunan secara berkala. Hasil analisis struktur menunjukkan bahwa tegangan lentur aktual pada semua kolom rumah Sumatera Selatan melebihi tegangan lentur ijin. Sedangkan tegangan lentur aktual pada 2 kolom rumah Sulawesi Utara masih diatas tegangan lentur ijin. Perbedaan luas dimensi ideal dengan luas dimensi aktual pada rumah adat Sumatera Selatan adalah 79.52% sehingga dimensi ideal yang dinilai mampu menahan beban 33/34. Sedangkan perbedaan luas dimensi ideal dengan dimensi aktual pada rumah Sulawesi Utara adalah 90%. sehingga diameter ideal yang mampu menahan beban d=40 cm. Evaluasi visual kekokohan bangunan dan analisis struktur dapat digunakan sebagai pertimbangan evaluasi kondisi rumah adat Sumatera Selatan dan Sulawesi Utara

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
