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: Analisis Peran Gender dalam Budaya Matrilineal, Manajemen Keuangan, dan Kesejahteraan Keluarga di Provinsi Sumatera Barat (Kasus pada Keluarga Pengrajin Bordir dan Sulaman)
Abstrak: West Sumatera is identical to the Minangkabau culture. Minangkabau culture has a unique culture compared to other cultures, and the only cultures in Indonesia that adopted matrilineal system. This research aimed to analyze gender role in matrilineal system, financial management activity, and family well-being in embroidery industry in West Sumatera. This research conducted in two districts: Kabupaten Lima Puluh Kota; Kota Bukittinggi. The data was collected on April until June 2012. There were 100 families as the sample of this research that was chosen purposively (respondent is wife/mother). The criteria of sample family are: intact family, there is at least a child that still enrolls in school, and the wife is get involved in the embroidery industry. The results showed that gender roles in decision making and division of labor in family were in a moderate level of gender partnerships between husband and wife in the family activities. The family financial management applied in moderate level, while the application of gender partnership has a low level. The family subjective well-being was showed by moderate level of wife satisfaction. The business income of women, gender roles of family financial management, and rural or urban location were dominant by factors that influenced family objective wellbeing; while the number of children, and gender roles in division of labor negatively effected the objective family well-being. The number of children, family income, application of family financial management were dominant by factors that influenced family subjective wellbeing; while the gender roles in division of labor, and rural or urban location negatively effected the subjective family well-being.

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.
