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.

Abstrak: Homegarden is land to conserve agricultural biodiversity. Various strata of the plants in the homegarden can provide beauty and comfort of the local environment. Land use and development homegarden has been carried out, but it has been more focused on family food availability. Currently, rate of tourism is growing so fast, so it is possible to land use change include homegarden. The purpose of this research is to identify patterns of land use in Taman Bunga Nusantara tourist area. This research is done at Cibodas village, Cibadak, Ciwalen, Kawungluwuk, and Cikanyere with take 40 home in each village as sample. There are 457 species (87 families) were used by residents as garden plants. Family which are found in every village is Agavaceae, Araceae, and Euphorbiaceae. Homegarden composition based on plant function in every village is homegarden with ornamental plants (more than 70%), vegetables (30-40%), perennials (5%), medicinal plants (5-60%), a source of carbohydrates (15-50%) and fruit trees (40-50%). Ornamental plants which are found in every village is Anthurium chrystallinum, Carex morrowi and Plathycerium coronarium.

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.
