Judul: Analisis Proses Keputusan Pembelian dan Kepuasan Konsumen Sayuran Organik Di Yogya Bogor Junction
Abstrak: Tujuan penelitian ini adalah (1) mengidentifikasi karakteristik konsumen sayuran organik di Yogya Bogor Junction (2) menganalisis proses keputusan pembelian sayuran organik (3) menganalisis kepuasan konsumen terhadap atribut sayuran organik. Penelitian dilaksanakan di Kota Bogor tepatnya di Yogya Bogor Junction yang terletak di Jl. Sawojajar Kota Bogor. Waktu penelitian dilakukan selama bulan Maret hingga Juni 2011. Fokus responden dalam penelitian ini adalah ibu rumah tangga. Penelitian ini menggunakan analisis deskriptif, Importance Performance Analysis (IPA) dan Customer Satisfaction Index (CSI). Responden yang mengkonsumsi sayuran organik memiliki karakteristik konsumen yang beragam. Kebanyakan berusia 24-30 tahun. Jenis pekerjaan dari responden yaitu sebagai pegawai swasta dengan pendapatan rata-rata perbulan yaitu Rp 3.500.000-Rp 4.500.000 dan pendidikan terakhirnya adalah sarjana. Pada tahap proses keputusan pembelian motivasi responden mengkonsumsi sayuran organik adalah sebagai salah satu pemenuhan pangan yang sangat bermanfaat bagi tubuh yaitu sebagai penembah gizi dan aneka vitamin yang berguna bagi tubuh. Atribut yang dipertimbangkan dari sayuran organik yaitu kesegaran sayuran organik. Sebagian besar responden Setelah mengkonsumsi sayuran organik merasakan puas dan responden tidak kesulitan dalam mendapatkan atau membeli sayuran organik. Akan tetapi jika sayuran organik yang diinginkan responden tidak tersedia, maka responden memilih mencari lokasi pembelian sayuran organik di tempat lain yaitu di Giant Botani Square. Secara keseluruhan responden mengkonsumsi sayuran organik sudah merasa puas yaitu dengan nilai CSI nya 74.26 persen. Atribut-atribut yang menjadi prioritas utama dan kinerjanya harus ditingkatkan berdasarkan analisis importance-performance yaitu atribut ketersediaan dan promosi sayuran organik. Atribut yang harus dipertahankan oleh pihak Yogya Bogor Junction yaitu kesegaran sayuran organik dan daya tahan sayuran organik.

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.
