Judul: Development of Urban Forest in Kalianda City, South Lampung District
Abstrak: Kota Kalianda merupakan ibukota Kabupaten Lampung Selatan yang sedang berkembang. Kota Kalianda memiliki satu hutan kota yaitu Hutan Kota Kalianda. Tujuan penelitian untuk mengidentifikasi permasalahan pengelolaan, menentukan motivasi, persepsi, serta preferensi masyarakat, dan menyusun strategi pengembangan hutan kota. Metode yang digunakan adalah studi literatur, observasi lapang, kuesioner, dan wawancara. Data dianalisis menggunakan skala Likert untuk penilaian motivasi, persepsi, dan preferensi masyarakat, dan strategi pengembangan hutan kota dianalisis menggunakan SWOT. Pengelolaan Hutan Kota Kalianda tidak berjalan dengan optimal karena tidak adanya rencana pengelolaan yang jelas. Motivasi pengunjung tertinggi (3,72) adalah untuk menghilangkan lelah (refreshing), persepsi tertinggi (4,43) hutan kota sebagai penghasil oksigen dan menyerap CO2, , dan preferensi tertinggi (4,55) menginginkan penambahan fasilitas tempat sampah. Strategi pengembangan hutan kota mengatasi kelemahan dengan memanfaatkan peluang yang sudah ada (Strategi WO)., The city of Kalianda is the capital of the which is developing South Lampung Regency. Kalianda City has one urban forest, namely Kalianda City Forest. The research objectives are to identify management problems, determine community motivations, perceptions, and preferences, and develop urban forest development strategies. Methods used are literature studies, field observations, questionnaires, and interviews. The data was analyzed using the Likert scale for motivational assessment, perception, and public preferences, and urban forest development strategies analyzed using SWOT. The management of the Kalianda City Forest is not running optimally because there is no clear management plan. The highest visitor motivation (3,72) was to relieve fatigue (refreshing), the highest perception (4,43) of the urban forest as a producer of oxygen and absorb CO2, and the highest preference (4,55) wanted additional trash can facilities. The urban forest development strategy overcomes weaknesses by taking advantage of existing opportunities (WO Strategy).

Judul: Lorensia Kali. Prediction of need urban forest use SIG and remote sensing. Case Study in Kabupaten Belu province of NTT
Abstrak: The aim of this research was to predict and identify need of urban forest based on production of Carbon Dioxide (CO2), also to identify spatial distribution and potent of developed urban forest. Prediction of urban forest carried out until 2020 with data base in 2003. This research used spatial analysis. The use of Analysis Hierarchy Process (AHP) to know alternatif scale what to do. Filled of cuisener on stackeholder such as; government, community, LSM, and the university. The result of this research to show that urban forest area in 2003 was 9.258,43 ha still enaugh need of urban forest until 2020 e.g. 207.701,666. However spatially despeard of urban forest were located in suburb. Based on Analysis Hierarchy Process, so the main alternatif was urban forest of housing, social community as second alternatif or priority. The third alternatif was urban forest conservation, and urban forest of recreation as four alternatif. The last alternatif was urban foret of industry.

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.
