Judul: Evaluasi Pemanfaatan Pekarangan dan Lahan Pertanian untuk Pengembangan Agrowisata di Desa Alamendah, Kecamatan Rancabali, Kabupaten Bandung.
Abstrak: Lanskap pedesaan memiliki karakteristik yang spesifik dan kaya akan sumber daya alam. Salah satu potensi yang dapat dikembangkan yaitu keberadaan lahan terbuka. Peningkatan nilai fungsi lahan terbuka perlu dikembangkan di antaranya, melalui pemanfaatan lahan pekarangan dan lahan pertanian untuk agrowisata guna meningkatkan kesejahteraan masyarakat desa dan keberlanjutan sistem pertanian. Penelitian ini bertujuan untuk mengidentifikasi karakteristik pekarangan dan lahan pertanian, menganalisis pemanfaatan lahan pekarangan dan lahan pertanian dari aspek fisik biofisik, sosial budaya, dan ekonomi, serta membuat rekomendasi pemanfaatan pekarangan dan lahan pertanian untuk pengembangan agrowisata. Penelitian ini dilakukan di Desa Alamendah Bandung pada bulan Maret hingga Agustus 2014 dengan menggunakan metode deskriptif dan kuantitatif. Metode yang digunakan yaitu metode Scenic Beauty Estimation (SBE) untuk menilai kualitas visual pada tapak secara kuantitatif dan analisis ekonomi untuk melihat aspek ekonomi pada pekarangan dan lahan pertanian. Hasil penelitian menunjukkan bahwa Desa Alamendah memiliki potensi pada pekarangan dan lahan pertanian untuk dikembangkan sebagai objek agrowisata. Hasil dari metode SBE menunjukkan bahwa 10% pekarangan masuk dalam katergori estetika tiggi, 53.3% estetika sedang, dan 36.7% estetika rendah. Sedangkan hasil dari penilaian pemandangan adalah 37% masuk dalam kategori estetika tinggi, 40% estetika sedang, dan 23% estetika rendah. Analisis ekonomi manunjukkan bahwa komoditas pertanian memiliki nilai B/C rasio diatas 1. Potensi-potensi yang ada dapat dikembangkan menjadi sebuah konsep “Wisata Pekarangan dan Pertanian”. Pengunjung dapat menikmati keindahan lanskap desa sekaligus belajar mengenai pertanian dengan praktek secara langsung.

Judul: Evaluasi potensi agrowisata di Desa Alamendah, Kecamatan Rancabali, Kabupaten Bandung
Abstrak: Region developing can cause land conversion, especially in agriculture land. The value of agriculture land can be increased by integrated usage with another related aspects such as art and local culture in agrotourism. Alamendah village has many agrotourism potencies from its nature and agriculture recources that can be developed. But, it had not been developed yet by the people, especially for local prosperity and environmental balances. The evaluation of agrotourism potency is needed with purpose to identify agrotourism potencies and former aspects, assess sustainability of community, evaluate agrotourism program and management, and make recommendation for agrotourism development. The research held in Alamendah Village, Rancabali Sub-district, Bandung district from February until July 2014 to get informations to be analyzed. Agrotourism aspects had been analyzed through agrotourism properness assessment, SWOT analysis, Community Sustainable Assessment (CSA) analysis, and preferences and perceptions analysis methods. Thus, from the analyze processes resulted the recommendation for agrotourism development at Alamendah village, such as the most suitable and potential areas for agrotourism development, potential view for agrotourism background and foreground, agrotourism development strategy, and agrotourism program and activity schedule. The final result proved that Alamendah village has a lot of potencies for agrotourism activity that can be developed with local people. The appropriate strategy to develop those potencies is make agrotourism activities and supporting tourisms being optimal for tourism activity to attract visitors, get much advantages and environment continuous.

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.
