Judul: Manajemen Pohon Pada Lanskap Boulevard Di Kawasan Kota Baru Alam Sutera Serpong, Tangerang
Abstrak: Alam Sutera terletak di daerah Serpong, Tangerang. Alam Sutera memiliki ruang terbuka hijau yang banyak jenisnya, salah satunya adalah lanskap jalan, di mana terdapat banyak sekali jenis karakter pohon yang perlu pengelolaan. Tujuan penelitian ini adalah menganalisis, mengevaluasi dan menyusun rekomendasi pengelolaan pohon. Pendekatan yang digunakan yaitu International Shadding Trees Evaluation Method (ISTEM) sehingga dapat diketahui nilai sebuah pohon. Berdasarkan hasil analisis pengukuran fisik pohon dan penilaian kondisi fisik pohon. Hasil penelitian menunjukkan kondisi fisik pohon pada lanskap boulevard ini tergolong banyak terkena serangan hama dan penyakit 67%, dan sangat sedikit yang terkena kerusakan mekanik 45%. Untuk itu maka dihasilkan rekomendasi pengelolaan pohon untuk kawasan boulevard di Alam Sutera ini. Rekomendasi yang disarankan bagi pohon yang terserang hama dan penyakit rayap, ulat daun, ulat kantung, kutu daun, semut, jamur upas, embun tepung, karat daun dan kanker batang dilakukan secara mekanis, fisik, biologi, karantina, teknik budidaya dan kimiawi dengan menggunakan pestisida yang ramah lingkungan (pestisida hayati tumbuhan dan pestisida nabati). Sedangkan pohon yang memiliki kerusakan fisik sehingga mempengaruhi visual pohon tersebut dalam bentuk vandalisme, goresan, sayatan, dan patah cabang disarankan untuk dilakukan pembenahan dengan cara pembersihan kerusakan dan pemangkasan.

Judul: Evaluasi Pengelolaan Lanskap Kawasan Permukiman Alam Sutera Serpong Kota Tangerang Selatan Provinsi Banten
Abstrak: Increased population growth occurring in urban areas has triggered increased residential development which led to the loss of open space in urban areas. The ideal maintenance shall be applied in order to reach the aesthetic, functional, and sustainable landscape. The specific objective of this internship was to evaluate the landscape management in residential area for improving the quality of the landscape in Alam Sutera. The internship program was conducted in PT Alam Sutera Realty from 10th March until 06th July 2014. Evaluation of landscape management at Alam Sutera has been done with descriptive and SWOT analysis. Descriptive analysis was performed to evaluate the efficiency and effectiveness of landscape management. Meanwhile SWOT analysis performed to evaluate the internal and external factors of landscape management. Based on the evaluation of efficiency and effectiveness, landscape management in Alam Sutera has been effective but not efficient. Meanwhile based on the evaluation of internal and external factors, the landscape management of Alam Sutera is in quadrant five that hold and maintain. The results of this analysis is an alternative strategy of landscape management by increasing the quality and quantity of employment, tools and nursery, and the quality of services at Alam Sutera Residences.

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.
