Abstrak: Ecological home garden is a knowledge that learn relationship between utilization patterns of home gardens and the owner to describe ecological area, socioeconomic, and culture of the owner. The research aim to compare the diversity of plant home garden in three sub districs of Depok City and the factors affect the home garden patterns. Identification and inventory of plants obtained 52 families and 142 species. This is including 129 species (51 families) in sub district Beji, 118 species (46 families) in sub distric Pancoran Mas, and 107 species (45 families) in sub district Sawangan. People in the three sub district more consederate their home garden in term of aesthetics value than the economic value. Therefore ornamental plants were more common than fruits crops, vegetables, and medicinal herbs. Since most people in the three sub district are employer and their home garden are less than 50 m2, they prefer to utilize the home garden for the ornamental plants than fruit crops and vegetable.

Judul: Comparison of the Utilization of Vegetation in the Yard of Four Villages in Cibungbulang District, Bogor Regency
Abstrak: Pekarangan merupakan sebidang tanah di sekitar rumah yang bersifat dinamis yang memiliki fungsi sebagai ekosistem, sosial, budaya serta ekonomi. Pemanfaatan pekarangan dapat meningkatkan aspek ekonomi masyarakat, sosial budaya, serta ekologis. Kecamatan Cibungbulang merupakan salah satu daerah sentra penghasil sayuran di Kabupaten Bogor yang mendukung pemerintah daerah pada sektor tanaman pangan. Hal ini diduga karena di kecamatan ini terdapat areal persawahan dan masyarakatnya memiliki dan memanfaatkan lahan pekarangan di sekitar rumah dengan baik. Oleh karena itu penelitian ini bertujuan untuk membandingkan keanekaragaman tanaman di pekarangan di empat desa di Kecamatan Cibungbulang. Penelitian ini juga menganalisis pola pemanfaatan pekarangan berdasarkan luasan, serta mengetahui persepsi masyarakat terhadap pemanfaatan pekarangan. Metode penelitian dimulai dengan observasi lapang secara purposive sampling, pengamatan tanaman, pembuatan herbarium dan identifikasi, wawancara, dan analisis data. Hasil penelitian menunjukkan tanaman yang berhasil diidentifikasi berjumlah 332 jenis dari 96 suku. Keanekaragaman tanaman yang tinggi dimiliki oleh desa Situ Udik dan Situ Ilir. Pola pemanfaatan pekarangan di keempat desa berdasarkan luasan memiliki jenis keragaman yang bervariasi mulai dari 1-10 jenis pada luas >50m2 hingga >30 jenis pada luas >300m2. Lahan pekarangan yang luas tidak selalu memiliki keanekaragaman tanaman yang tinggi. Tingkat pendidikan dan penghasilan dapat mempengaruhi persepsi masyarakat terhadap pemanfaatan lahan pekarangan. Masyarakat di keempat desa lebih memilih jenis pekarangan yang produktif dan bernilai ekonomi., The yard is a dynamic plot of land around the house that is dynamic in nature which has an ecosystem, social, culture and economic function. Utilization of the yard can improve the economic, socio-cultural and ecological aspects of the community. Cibungbulang District is one of the vegetable producing centers in Bogor Regency which supports local governments in the food crop sector. The community in that area are suspected of having well-cultivated rice fields and yards. This study aims to compare the diversity of plant species, to analyze pattern of yard utilization based on the area , and to analyze the public perception of the pattern of yard use in four villages in Cibungbulang District. The research method begins with field observations, determining the sample yard by purposive sampling, plant species collecting, making a herbarium for identification purposes and interviews with respondents. The data is processed in the form of percentages and grouped. The results showed that there were 332 plant species classified into 96 families. Situ Udik and Situ Ilir villages have higher plant diversity. Species diversity varies in yards with different size. There are 1-10 plant species in yards size larger than 50 m2 to more than 50 species in yards area larger than 300 m2. The level of education and income can affect people's perceptions of the use of yards, so that large yards do not always have high species diversity. Communities in the four villages prefer the type of yard that is productive and economically profitable.

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.
