Judul: Analisis Jasa Biodiversitas dan Estetika Lanskap pada Pekarangan di Kota Bogor.
Abstrak: Lanskap perkotaan adalah lanskap yang rentan terhadap permasalahan yang disebabkan tingginya perubahan tata guna lahan, sebagai akibat dari tingginya tingkat migrasi. Alhasil, fragmentasi lanskap berkembang dan lanskap alami harus menanggung akibatnya. Pekarangan, sebagai lanskap agroforestri skala mikro, memegang peran yang penting dalam menyediakan jasa lanskap untuk mengurangi dampak dari permasalahan akibat perubahan tata guna lahan untuk permukiman. Tujuan dari penelitian ini adalah menganalis tingkat biodiversitas tanaman dan kualitas estetika pada pekarangan dan menyusun rekomendasi berbasis jasa lanskap biodiversitas tanaman dan estetika. Metode dari penelitian ini terdiri dari tahap persiapan, inventarisasi tapak dan pengumpulan data, analisis jasa biodiversitas tanaman dengan indeks Shannon Wiener (H’), analisis jasa kualitas estetika lanskap dengan Scenic Beauty Estimation (SBE), dan penyusunan rekomendasi pengelolaan. Nilai H’ tertinggi, yaitu 3,32 ditemukan di Kelurahan Babakan, Kecamatan Bogor Tengah, dan nilai H’ terendah, yaitu 1,22 ditemukan di Kelurahan Bondongan, Kecamatan Bogor Selatan. Nilai SBE tertinggi, yaitu 150,48 berada di Kelurahan Empang, Kecamatan Bogor Selatan, sedangkan nilai SBE terendah, yaitu -74,29 ditemukan di Kelurahan Menteng, Kecamatan Bogor Barat. Berdasarkan hasil analisis tersebut, terdapat beberapa rekomendasi yang diusulkan untuk peningkatan biodiversitas dan kualitas estetika pada pekarangan. Rekomendasi tersebut mencakup pemilihan tanaman multifungsi dan multilayered, penerapan pola desain, pengelolaan berbasis low maintenance, serta pendidikan dan pemberdayaan masyarakat.

Judul: Rural Landscape Management as a Landscape Service Provider in Cikarawang and Margajaya Village Bogor
Abstrak: Lanskap pedesaan memiliki potensi alam yang melimpah. Salah satu potensi alam tersebut adalah jasa lanskap. Jasa lanskap perlu dioptimalkan pengelolaan dan pemanfaatannya. Hal terpenting dalam pemanfaatannya adalah dengan tetap memperhatikan keseimbangan ekosistem untuk menciptakan lanskap yang berkelanjutan. Tujuan penelitian ini adalah menganalisis data karakter spasial desa, menganalisis potensi jasa lanskap desa, dan menyusun rekomendasi pengelolaan potensi jasa lanskap desa. Penelitian ini dilaksanakan di Desa Cikarawang, Kecamatan Dramaga, Kabupaten Bogor dan Kelurahan Margajaya, Kecamatan Bogor Barat, Kota Bogor. Penelitian ini dilakukan dengan menganalisis empat aspek jasa lanskap, yaitu biodiversitas menggunakan Indeks Shannon Wienner, cadangan karbon menggunakan estimasi biomassa, keindahan lanskap menggunakan metode Beautification Rate Index (BRI) dan sumberdaya air menggunakan Normalized Difference Water Index (NDWI). Rekomendasi strategi pengelolaan jasa lanskap menggunakan analisis SWOT yang mempertimbangkan faktor internal (kekuatan dan kelemahan) dan faktor eksternal (peluang dan ancaman)., Rural landscapes have abundant natural potential. One of these natural potentials is landscape services. Landscape services need to be improved in their management and utilization. The most important thing in its use is to maintain the balance of the ecosystem to create a sustainable landscape. The purpose of this study is analyze data on the spatial character of the rural landscape, analyze the potential of rural landscape services, and compile recommendations for managing the potential of rural landscape services. This research carried out in Cikarawang Village, Dramaga Sub-district, Bogor District and Margajaya Urban Village, West Bogor Sub-district, Bogor City. This research conducted by analyzing four aspects of landscape services, there are biodiversity using the Shannon Wienner Index, carbon stock using biomass estimation, landscape beauty using the Beautification Rate Index (BRI) method, and water resource management using the Normalized Difference Water Index (NDWI) method. Landscape services management strategy used SWOT analysis that considers internal factors (strengths and weaknesses) and external factors (opportunities and threats).

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.
