Judul: The existence of bajapuik, a minangkabau marriage tradition practiced in Pariaman , West Sumatra
Abstrak: One model of marriage tradition that often gets the spotlight is bajapuik, an action of giving a sum of money or uang japuik to the prospective bridegroom by the prospective brides’ family. The tradition, which is only practiced by Minangkabau people from Pariaman, contradicts to the rules of marriage in Islam of which the bridegroom has to give something as a present or mahar to the bride. Today, the amount of uang japuik has continuously increase as the socioeconomic status of prospective bridegroom improves. This has resulted in financial burden to the prospective brides’ family. Therefore, this study is aimed to find out what values, basic forms of exchange in bajapuik tradition marriage and factors affecting the changes. It is also aimed to identify who are involved and what are their roles in the bajapuik tradition. Finally it is intended to analyse what are the reasons why bajapuik tradition is still exist in a changing society. Post-positivism paradigm was used to answer these problems and both quantitative and qualitative methods were employed. Data was collected through a survey, in-depth, participant observation, documentation and literature study. Respondents and informants of the research were the people living in surrounding areas of Pariaman. They are chosen on the basis of purposive and snowballing sampling method, The respondent were young, middle and old generation, while the informants were people of KAN (Kerapatan Adat Nagari); and ex-KAN; LKAAM (Lembaga Kerapatan Alam Adat Minangkabau) and tiga tungku sajarangan. This study shows that bajapuik tradition with the uang japuik still exists in the society because it is continuously experiencing adjustments, until present time. This is manifested is the exchange of the basic changes from the title of nobility (ascribed status) to the socio-economic status (achievement status), although the bases of the exchange value is still the same, that is cultural values. Exchange in bajapuik tradition involves actors from the families, which consists of parents, mamak and ninik mamak. The amount tradition of bajapuik money depent on the socioeconomic status of prospective bridegroom. The existence of bajapuik tradition in the social context until the present time is supported by families both parties who share the same values and internal solidarity among the family members.

Judul: The cultural attachment of matrilineal traditions with gender roles in Minang Migrant Households (Case : Ikatan Keluarga Minang In&#160;East&#160;Jakarta)
Abstrak: Masyarakat Minangkabau merupakan masyarakat yang menganut sistem keturunan Ibu atau sistem matrilineal sebagai aturan budaya dalam kehidupan sehari-hari. Budaya matrilineal erat kaitannya dengan hak dan kepemilikan sumber daya atau harta pusaka dalam silsilah keluarga masyarakat Minang. Perempuan mendapatkan akses memanfaatkan sumber daya dalam keluarga dan laki-laki memiliki fungsi mengawasi dan memelihara sumber daya tersebut. Tujuan dari penelitian ini adalah untuk menganalisis hubungan implementasi budaya matrilineal dengan pembagian peran gender pada rumah tangga Minang yang ada di perantauan. Penelitian ini menggunakan uji korelasi rank spearman dengan jumlah responden 35 rumah tangga yang diambil secara sensus pada komunitas Ikatan Keluarga Minang di Kecamatan Cakung. Hasil penelitian menunjukkan bahwa perempuan pada rumah tangga perantau Minang bukanlah pemilik penuh dalam sumber daya materi tetapi sebatas memanfaatkan dan mengakses sumber daya tersebut dan laki-laki memiliki hak untuk mengontrol sumber daya dalam keluarga. Keistimewaan terhadap perempuan Minang terletak pada penentuan setiap suku pada garis keturunan mengikuti suku Ibu. Hasil penelitian juga menunjukkan bahwa masih terdapat ketimpangan dalam pembagian peran gender di rumah tangga perantau Minang. Perempuan masih menghadapi beban kerja ganda dengan reproduktif lebih banyak dikerjakan oleh perempuan dibandingkan laki-laki., The Minangkabau community is a society that follows a matrilineal system, or a maternal lineage system, as a cultural rule in their daily lives. This matrilineal culture is closely related to the rights and ownership of resources or heritage within the Minang family’s lineage. Women have access to utilize these resource within the family, while men are responsible for supervising and maintaining these resources. The aim of this research is to analyze the relationship between the implementation of matrilineal culture and gender roles in Minang households abroad. The study uses the spearman rank correlation test with a sample size of 35 households, taken as a cencus from the Ikatan Keluarga Minang community in the Cakung district. The result show that women in Minang migrant households do not fully own material resources but only have access to utilize these resources, whereas men have the right control the family resources. The distinction for Minang women lies in the dertemination of each clan following the maternal lineage. The research also indicates that there is still inequality in the distribution of gender roles in Minang migrant households. Women still face a double workload, with reproductive tasks being predominantly perfomed by women compared to men.

Judul: Pemurnian dan karakterisasi protein inhibitor RNA helikase virus hepatitis C
Abstrak: Hepatitis C virus (HCV) infection is the second most common chronic viral infection in the world with global prevalence. This infection is contribution to chronic hepatitis and liver cirrhosis, often leading to hepatocellular carcinoma. There is no effective drug and vaccine available against HCV. The current standard treatment, a combination of pegylated interferon-α with ribavirin, is limited by its suboptimal response rate in a significant patient population, side effects, and affordability. Therefore, development of effective drug is needed. One approach to find out the candidate of antiviral drug is to discover the inhibitor of enzyme that essential for virus replication, such as RNA helicase. Streptomyces chartreusis 5-095 produce the inhibitor of HCV RNA helicase. The aim of this study was to purify the protein inhibitor which has inhibition activity against ATPase activity of RNA helicase HCV from S. chartreusis 5-095. The supernatant of culture S. chartreusis 5-095 exhibited high inhibiton activity against ATPase activity of RNA helicase HCV (approximately 72%) at 10 days of incubation. The extracellular protein inhibitor was partially purified by procedures of precipitation with ammonium sulfate to 65% saturation and gel filtration (Sephadex G50) using methanol water solution (4:6) as an eluen. The purity of protein inhibitor was monitored by SDS PAGE. The protein inhibitor showed a relative molecular mass were estimated to be 14 kDa and increased the purity 23,08 fold than those of the crude protein. The specific activity and IC50 after purification were 13,1338 U/mg and 0,0767 mg/mL, respectively. The activity of purified protein inhibitor showed its stability over pH range from 5-8 and optimum at pH 7,4. The inhibition activity showed its stability up to 70% at temperature 100 oC. The purified protein inhibitor relatively stable its activity at storage in the range of -20 oC to room temperature for 35 days.
