Judul: Effects of Green Products For Consumer Purchase Intention Among Students In Indonesia and Malaysia: A Comparative Study
Abstrak: Munculnya kesadaran akan isu lingkungan telah memicu sektor industri untuk menciptakan konsep pemasaran yang mempromosikan isu lingkungan atau lebih dikenal dengan green poduk. Tujuan dari penelitian ini adalah (1) untuk menguji pengaruh green products terhadap minat beli konsumen pada Mahasiswa di Indonesia dan Malaysia dan (2) membandingkan pengaruh green products terhadap minat beli konsumen pada Mahasiswa di Indonesia dan Malaysia. Penelitian ini dilakukan di Malaysia dan Indonesia. Survei kuesioner telah dilakukan pada 208 responden di Indonesia & Malaysia. Data dianalisis dengan deskriptif, cross tabulation, dan Structural Equation Modeling Partial Least Square (SEM-PLS). Hasil penelitian ini menunjukkan bahwa baik di Indonesia maupun di Malaysia, green products mempengaruhi citra merek, sikap konsumen dan minat beli. Namun terjadi perbedaan pada citra merek dan sikap konsumen terhadap minat beli. Di Indonesia, citra merek tidak berpengaruh terhadap minat beli, sedangkan Malaysia citra merek berpengaruh terhadap minat beli. Selain itu, di Indonesia sikap konsumen berpengaruh terhadap minat beli, sedangkan di Malaysia sikap konsumen tidak berpengaruh terhadap minat beli. Di Indonesia, minat beli lebih dipengaruhi oleh green products, sedangkan di Malaysia, minat beli lebih dipengaruhi oleh citra merek

Judul: The Influence of Knowledge and Word of Mouth toward Attitudes and Intention to Buy Green Product
Abstrak: Sikap dan minat beli produk ramah lingkungan merupakan salah satu implementasi dari masyarakat yang bertanggung jawab terhadap lingkungan. Informasi mengenai lingkungan dan word of mouth telah tersebar luas serta mudah ditemukan di berbagai media, terutama media sosial. Tujuan penelitian ini adalah untuk menganalisis hubungan karakteristik responden dengan pengetahuan lingkungan, word of mouth¸ sikap peduli lingkungan, dan minat beli produk ramah lingkungan. Selain itu, menganalisis pengaruh pengetahuan lingkungan dan word of mouth terhadap sikap peduli lingkungan dan minat beli produk ramah lingkungan. Penelitian ini menggunakan mix methods. Penelitian kuantitatif dilakukan dengan teknik survei online pada 159 orang responden. Penelitian kualitatif dilakukan dengan in-depth interview dengan 10 orang responden yang dipilih menggunakan teknik purposive sampling serta observasi pada retail online dan offline. Analisis data dilakukan menggunakan aplikasi SPSS 25.0 dan SEM LISREL 8.80. Hasil uji hubungan menunjukkan terdapat hubungan signifikan antara usia, pekerjaan, dan rata-rata pengeluaran dengan minat beli produk ramah lingkungan. Hasil analisis SEM pada penelitian juga menunjukkan pengaruh positif signifikan antara pengetahuan lingkungan dan word of mouth terhadap sikap peduli lingkungan dan minat beli produk ramah lingkungan, serta menunjukkan pengaruh signifikan secara positif antara sikap peduli lingkungan terhadap minat beli produk ramah lingkungan. Oleh karena itu, masyarakat perlu meningkatkan pengetahuan mengenai lingkungan, diharapkan juga masyarakat dapat membagikan ulasan produk sebagai referensi bagi calon konsumen lain sebelum membeli produk tersebut. Hasil penelitian juga dapat dimanfaatkan untuk meningkatkan minat beli produk ramah lingkungan di Indonesia. Diharapkan pemerintah dan organisasi terkait lingkungan dapat bekerja sama dalam menyebarluaskan informasi mengenai lingkungan yang aktual dan terkini., The attitude and intention to buy green products is one of the implementations of a society responsible for the environment. Information about the environment and word of mouth has spread widely and is easy to find on social media. This study analyzed the relationship between respondent characteristics and environmental knowledge, word of mouth, environmental attitudes, and intention to buy green products. It also analyzed the influence of environmental knowledge and word of mouth on environmental attitudes and intention to buy green products. This research uses mixed methods. Quantitative research was conducted using an online survey technique on 159 respondents. Qualitative research was conducted using in depth interviews with ten selected respondents and observations of online and offline retailers. Data analysis was performed using SPSS 25.0 and SEM-LISREL 8.80. The relationship test results in this study showed a significant relationship between age, occupation, and expenditure with an intention to buy green product. The results of the SEM analysis in the study showed a significant positive influence between environmental knowledge and word of mouth on environmental attitudes and intention to buy green products. Also, environmental attitudes showed a significant positive influence on the intention to buy green products. Therefore, the community needs to increase its environmental knowledge. The community can share product reviews as a reference for other potential consumers. The research results can also be used to increase the intention to purchase green products in Indonesia. It is hoped that the government and organizations can disseminate information about the actual and current information.

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.
