Abstrak: Sindang Barang Experimental Field (KPSB) is one of a supporting facilities for research, education, and community service. KPSB is one of University Farm (UF) of IPB, with total area 78 750 m2, consist of planting Bloks, research garden, building, and supporting facilities. Recently, KPSB is not used optimally and and not put in good use due to lack of facilities. Therefore, landscape design of KPSB is needed as a reference for future development of KPSB. The purpose of this study is designing an experimental field with techno-ecologycal farming concept. This research used survey and descriptive method with the design phase approach followed Bell (2008). The main design concept is techno-ecological agro tourism. This design was not only concern about research and education activities, but also how to support agro tourism. The zoning in this design are: welcome area (9%), agriculture (27%), education (23%), fisheries (11%), talun (20%), and tourism (10%). In the future, it is expected that agrotourism activities can be done well on KPSB.

Judul: "Tjikoepa Farm" Agrotourism Landscape Design in Sukanagara District, Cianjur Regency
Abstrak: Laju pertumbuhan penduduk Kabupaten Cianjur terus meningkat dengan laju pertumbuhan tahunan sebesar 1,26%. Pertambahan penduduk ini membawa konsekuensi pada kebutuhan akan lahan untuk pemukiman, sehingga alih fungsi lahan pertanian tidak dapat dihindari. Untuk menekan laju konversi lahan dapat ditempuh melalui pemanfaatan lahan yang kurang produktif menjadi lahan produktif multifungsi, misalnya dengan membangun agrowisata. Salah satu lahan yang belum dimanfaatkan secara optimal adalah lahan pertanian seluas 3 hektar milik Tjikoepa Farm di Sukanagara, Kabupaten Cianjur. Perlu dirancang menjadi agrowisata. Tujuan penelitian ini adalah merancang lahan pertanian kurang produktif menjadi lanskap agrowisata yang dapat memenuhi kebutuhan penginapan dan wisata Kabupaten Cianjur. Metode yang digunakan dalam penelitian ini adalah metode deskripsi melalui pendekatan desain lanskap berbasis program. Kegiatan dan komoditas pertanian ditentukan oleh pemilik lahan. Konsep perancangan yang dianut adalah wisata pertanian terpadu modern dengan mempertimbangkan low external input and sustainable agriculture (LEISA). Wisata dirancang untuk memaksimalkan potensi pertanian terpadu yang bersifat edukatif dan memberikan pengalaman yang lebih inspiratif dan menyenangkan bagi pengunjung mulai dari anak-anak hingga orang dewasa. Fun farming agrotourism merupakan konsep wisata yang dilakukan di kawasan ini yang meliputi kegiatan belajar, pengayaan, rekreasi/kuliner, outbond, dan festival pertanian. Untuk itu, ruang yang dibentuk meliputi kawasan pelayanan, kawasan wisata kuliner, kawasan wisata pertanian (hortikultura, perkebunan, peternakan, dan perikanan), kawasan outbond, kawasan glamping, kawasan konservasi, dan tempat pandang. Pengunjung dimanjakan dengan segala panca inderanya sepanjang perjalanan mulai dari tempat parkir hingga level tertinggi di tempat pandang atau view point, termasuk pengalaman mereka di setiap kawasan wisata.

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.
