Abstrak: Persaingan bisnis semakin tinggi membuat perusahaan harus meningkatkan daya saing dari kompetitor dimana tidak fokus ke profit tetapi juga planet dan people contohnya dengan produksi green product. Tingginya pertumbuhan dan pendapatan industri kosmetik per tahun serta semakin banyaknya merek kosmetik organik yang beredar sehingga penting untuk mengetahui faktor dominan dari Theory of Planned Behavior yang mempengaruhi green purchase intention serta pengaruh attitude, subjective norm dan perceived behavior control terhadap green purchase intention. Metode penelitian ini adalah kuantitatif deskriptif dengan pengumpulan data menggunakan kuesioner yang disebarkan kepada 200 orang Jabodetabek berusia minimal 18 tahun, serta menggunakan kosmetik organik. Adapun analisis data penelitian ini adalah deskriptif dan SEM PLS menggunakan aplikasi Smartpls 3.0 dan Excel. Hasil yang diperoleh menunjukan bahwa attitude, subjective norm dan perceived behavior control berpengaruh positif signifikan terhadap green purchase intention dan subjective norm merupakan faktor dominan yang mempengaruhi green purchase intention., Business competition is increasingly high that companies must increase their competitiveness from competitors by implementing green products. The high growth and income of the cosmetics industry per year and the increasing number of organic cosmetic brands in circulation make it important to focus on profit but also the planet and people, for example by producing green products. The high growth and income of the cosmetics industry per year and the increasing number of organic cosmetic brands in circulation make it important to know the dominant factors from the Theory of Planned Behavior that influence green purchase intention and the influence of attitude, subjective norms and perceived behavior control on green purchase intention. This research method was descriptive quantitative with data collection used a questionnaire distributed to 200 Jabodetabek people aged at least 18 years, and who used organic cosmetics. The data analysis used SEM PLS and descriptive used the Smartpls 3.0 and Excel applications. The results obtained show that attitude, subjective norms and perceived behavior control had a significant positive effect on green purchase intention and subjective norm was dominant factor influenced green purchase intention

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.
