Judul: Rencana Pengelolaan Lanskap Eco-Art Park di Sentul City, Bogor
Abstrak: In an effort to realize the concept of Sentul City as a destination and a knowledge city, PT Sentul City Tbk. developed a recreational facility by building ecopark. Sustainable management of the landscape ecopark may have implications for the Sentul City as an eco city. The purpose of this study is to analyze the implementation of the existing landscape, evaluation of landscape development, and make landscape management plan. With the research object Eco-Art Park Sentul City, this study used methods of surveys, questionnaires, interviews, and Analytical Hierarchy Process (AHP). Analysis of the implementation of the existing landscape Eco-Art Park Sentul City shows that the landscape has not fulfilled the criteria of ecological park. Basic concepts and landscape development has not led to the ecological park. Development landscape changes related to adjustments and the desire of the directors. In the management and maintenance of landscapes, operationally not lead to ecological park. In the preparation of the management plan, there are recommendations to restructure the management and the addition of landscape maintenance schedule.

Judul: Evaluasi Pengelolaan Lanskap Permukiman Kawasan Sentul City, Bogor
Abstrak: Perkembangan kota saat ini yang padat dengan penduduk menuntut ketersediaan sarana dan prasarana yang menunjang aktivitas maupun kebutuhan. Keterbatasan lahan menjadi salah satu kendala dalam pemenuhan hal tersebut, khususnya pada perkotaan yang diakibatkan peningkatan kawasan industri, pembangunan fisik, dan pertumbuhan ekonomi (Wiradisuria 1983). Solusi dalam hal ini adalah pembangunan permukiman pada pinggiran kota. Salah satunya kawasan Sentul City, Bogor yang merupakan kota baru yang terencana yang memiliki konsep eco city. Pembangunannya sangat memperhatikan kebutuhan permukiman mencakup sarana dan prasarana memadai serta memberikan kenyamanan penghuni. Kegiatan magang skripsi berlangsung pada minggu terakhir Februari 2012 hingga minggu terakhir bulan Mei 2012. Kegiatan ini dilakukan di Unit Lanskap dan Kebersihan, Departemen Pemeliharaan Kota, PT. Sukaputera Graha Cemerlang. Dalam pelaksanaan kegiatan magang ini mahasiswa mempelajari organisasi dan mekanisme kerja perusahaan dan berpatisipasi aktif dalam proses pemeliharaan lanskap. Pemeliharaan lanskap ini mencakup kawasan permukiman Sentul City dengan luas kawasan pemeliharaan sebesar 297 ha. Kawasan pemeliharaan ini meliputi taman yang terdapat di sepanjang jalan utama, taman lingkungan di setiap cluster, dan kawasan RTH. Kegiatan pemeliharaan ini pihak pengelola bekerjasama dengan pihak kontraktor yaitu CV. Gelar Jaya, CV Cipta Anugrah Maulita, dan PT. Makna Prakarsa Utama.

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.
