Judul: The Effect of Taste Trough Product  Innovation on Consumer Purchase Intention of Instant Rolled Oat Product in  Jabodetabek
Abstrak: Minat beli konsumen pada suatu makanan diduga dipengaruhi oleh cita rasa dan inovasi produk. Oat merupakan produk kaya manfaat dengan tingkat konsumsi di Indonesia rendah karena rasanya yang hambar dan kurangnya pengetahuan tentang inovasi produk instant rolled oat. Penelitian ini bertujuan untuk menganalisis pengaruh cita rasa melalui inovasi produk terhadap minat beli konsumen di Jabodetabek pada produk instant rolled oat. Jumlah sampel yang diteliti sebanyak 280 responden dengan metode purposive sampling yang memiliki kriteria berdomisili di Jabodetabek, berusia 17 tahun ke atas, dan pernah atau belum pernah membeli produk instant rolled oat. Data dikumpulkan melalui penyebaran kuesioner. Metode yang digunakan adalah metode analisis deskriptif dan analisis SEM-PLS. Hasil penelitian menunjukkan bahwa terdapat pengaruh cita rasa dan inovasi produk terhadap minat beli konsumen secara positif dan signifikan serta terdapat pengaruh cita rasa terhadap inovasi produk secara positif dan signifikan. Hasil lain juga menunjukkan adanya pengaruh tidak langsung cita rasa terhadap minat beli konsumen yang dimediasi oleh inovasi produk secara positif dan signifikan., The consumer purchase intention in a food is thought to be influenced by taste preferences and product innovation. Oats products have many benefits but low consumption levels in Indonesia due to their bland taste and lack of knowledge about instant rolled oat product innovation. This study aims to analyze the effect of taste through product innovation on consumer purchase intention of instant rolled oat product in jabodetabek. The number of samples studied was 280 respondents using the Purposive sampling method who had the criteria of domiciled in Jabodetabek, aged 17 years and over, and had or had not purchased instant rolled oat product. Data was collected through the distribution of questionnaires. The method used is descriptive analysis method and SEM-PLS analysis. The results of the study show that there is a positive and significant effect of taste preference and product innovation on consumer purchase intention and there is a positive and significant influence of taste on product innovation. Other results also show that there is an indirect effect of taste preference on purchase intention which is mediated by product innovation positively and significantly.

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.
