Judul: Dampak Keberadaan Ruang Terbuka Hijau terhadap Harga Pemukiman di Perumahan Berkonsep Green Living Kota Bumi Serpong Damai Tangerang
Abstrak: The Green BSD is one of residential that has a concept of green living. House prices offered is the value of the characteristics of the housing itself. The presence of a green residential area which emphasizes aspects of green open space is able to add value to the house so that makes its price higher. Research objectives of this study were to identify community perceptions in assessing the aspect of the existence of green open space as seen from its presence either in public or private around the houses, identification of factors that affect the price of the house and the analysis of the effect of green space on house prices, and estimates the economic value of ecosystem services of green open space. The method used in this study is a descriptive analysis and hedonic price method. The result showed that respondents have good perceptions about the presence of public green open space and private green open space located around housing. Based on the results of the double log regression analysis, the factors that affect the price of the house that is the distance to the place of worship, public park distance to the house, spacious yard, and a number of house windows. The economic value of green space is IDR 243.103.448,8. This value is the willingness and ability of people to make opportunity to get the benefits of green space that is represented in house prices.

Judul: Analisis Faktor-Faktor Yang Memengaruhi Willingness To Pay Masyarakat Terhadap Ruang Terbuka Hijau Di Kota Bogor (Studi Kasus: Taman Kresna) Mahasiswa Institut Pertanian Bogor
Abstrak: Pembangunan Kota Bogor sesuai dengan Rancangan Pembangunan Jangka Menengah Daerah (RPJMD) tahun 2015-2019 dan 2019-2024 mewujudkan pembangunan berkelanjutan dengan berawawasan lingkungan. Undang-Undang Nomor 26 tahun 2007 menetapkan total luas kebutuhan minimum RTH adalah 30% dari luas wilayah kota. Proporsi RTH Kota Bogor saat ini baru mencapai 4,18% dari luas kota. Tujuan penelitian ini adalah mengidentifikasi persepsi masyarakat mengenai fungsi dan kondisi keberadaan Taman Kresna sebagai Ruang Terbuka Hijau (RTH), mengestimasi nilai ekonomi keberadaan Taman Kresna, mengidentifikasi faktor yang memengaruhi besarnya nilai WTP masyarakat dalam menjaga dan meningkatkan kualitas keberadaan Taman Kresna. Metode analisis yang digunakan dalam penelitian ini adalah analisis deskriptif, analisis regresi logistik, dan analisis contingent valuation method (CVM). Hasil penilitian ini menujukan bahwa persepsi dan kepedulian masyarakat terhadapat Taman Kresna adalah cukup baik. Hasil rata-rata WTP dengan menggunakan Contingent Valuation Method (CVM) dari 86 responden yang bersedia berpartisipasi adalah sebesar Rp. 21.643 per orang per tahun.. Faktor yang berpengaruh secara signifikan terhadap kesediaan masyarakat dalam upaya menjaga dan meningkatkan kualitas keberadaan Taman Kresna adalah usia, pendidikan, tanggungan keluarga, jarak dan frekuensi kunjungan.

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.
