Judul: Evaluation of Urban Landscape Comfort with Amenity Index Approach in Tangerang City
Abstrak: Laju kepadatan penduduk Kota Tangerang mengalami kenaikan yang cukup signifikan setiap tahunnya. Fenomena tersebut meningkatkan pembangunan kota yang dapat mengganggu keseimbangan lingkungan dan berdampak buruk pada kenyamanan lanskap. Tujuan penelitian ini adalah menganalisis persepsi masyarakat dan mengevaluasi kenyamanan lanskap berdasarkan Urban Landscape Quality Index (ULQI), melakukan pemetaan kenyamanan dan menyusun rekomendasi untuk meningkatkan kenyamanan lanskap Kota Tangerang. Metode yang digunakan dalam penelitian ini adalah metode ULQI. Analisis persepsi masyarakat mengacu pada survei pengisian kuisioner dan menghitung nilai ULQI mengacu pada penilaian visual elemen lanskap. Berdasarkan evaluasi di enam kecamatan, lanskap Kota Tangerang tergolong baik dengan nilai analisis sebesar 75,5 dan nilai ULQI sebesar 2,65. Pemetaan tingkat kenyamanan lanskap mengalami perbedaan dengan tingkat akurasi sebesar 60%. Rekomendasi yang diajukan terfokus pada Batuceper dan Larangan sebagai kecamatan dengan nilai terendah. Usulan berupa peningkatan kuantitas dan kualitas Ruang Terbuka Hijau, taman bermain, jalur sepeda, trotoar, tempat pengelolaan limbah, lapangan olahraga, dan ruang parkir., The population density rate of Tangerang City has increased significantly every year. This phenomenon increases urban development which can disrupt the environmental balance and adversely affect the comfort of the landscape. The purpose of this study was to analyze public perceptions and evaluate the comfort of the landscape based on the Urban Landscape Quality Index (ULQI), to map the comfort and to develop recommendations to improve the comfort of the Tangerang City landscape. The method used in this study is the ULQI method. The analysis of public perceptions refers to the survey filling out the questionnaire and calculating the ULQI score refers to the visual assessment of landscape elements. Based on the evaluation in six sub districts, the Tangerang City landscape is classified as good with an analysis value of 72,7 and a ULQI value of 2,7. Mapping the comfort level of the landscape is difference with an accuracy rate of 60%. Recommendations focus on Batuceper and Larangan as the sub districts with the lowest score, in the form of increasing the quantity and quality of green open spaces, playgrounds, bicycle lanes, sidewalks, waste management areas, sports fields, and parking spaces.

Judul: Evaluation of Comfort Valeu and Aesthetics Level of BSD City Park South Tangerang.
Abstrak: Perkembangan kota mendorong terbentuknya kota-kota baru di sekitar kotakota besar sebagai tempat tinggal alternatif yang disebut kota mandiri. Kawasan Bumi Serpong Damai (BSD) City adalah kota mandiri yang terletak di Kota Tangerang Selatan, Banten. Kawasan BSD City berbatasan langsung dengan DKI Jakarta, menjadikannya sebagai tempat alternatif bagi masyarakat DKI Jakarta yang telah sangat meningkat. BSD City adalah kota baru dengan konsep permukiman ramah lingkungan yang memiliki ruang terbuka hijau (RTH) untuk menciptakan lingkungan perkotaan yang indah. RTH yang tersedia di kawasan BSD City ada yang berupa taman kota yaitu Taman Kota 1 BSD dan Taman Kota 2 BSD. Penelitian ini dilakukan di Taman Kota 1 BSD dan Taman Kota 2 BSD dengan tujuan yaitu mengidentifikasi jenis dan fungsi tanaman, mengevaluasi fungsi ekologis dan estetika RTH, dan memberikan hasil berupa rekomendasi perbaikan serta penataan tanaman untuk meningkatkan kenyamanan dan estetika taman. Hasil penelitian menunjukkan jumlah pohon pada Taman Kota 2 BSD lebih banyak dibandingkan Taman Kota 1 BSD, sedangkan jumlah spesiesnya lebih beragam pada Taman Kota 1 BSD. Hasil penilaian berdasarkan fungsi tanaman dalam modifikasi suhu dan kontrol kelembaban pada Taman Kota 1 BSD dan Taman Kota 2 BSD termasuk kategori baik. Berdasarkan fungsi penahan angin pada Taman Kota 1 BSD juga termasuk kategori baik, sedangkan Taman Kota 2 BSD berkategori sedang. Hasil pengukuran juga menunjukkan kedua taman tersebut efektif dalam ameliorasi iklim mikro apabila dibandingkan dengan suhu rata-rata dan kelembaban rata-rata di luar taman. Penilaian estetika menunjukkan Taman Kota 1 BSD dan Taman Kota 2 BSD masuk dalam kategori estetika tinggi. Responden juga sebagian besar sudah merasa puas dengan kondisi kedua taman kota tersebut saat ini tapi menyarankan agar adanya perbaikan fasilitas yang telah rusak. Responden juga menyarankan penambahan tanaman yang lebih bervariasi seperti tanaman berbunga untuk menambah nilai estetika taman., The development of cities encourages the formation of new cities around big cities as alternative living areas, which are called independent cities. Bumi Serpong Damai (BSD) City area is an independent city located in South Tangerang City, Banten. It is directly adjacent to DKI Jakarta, making it an alternative area for DKI Jakarta residents who have greatly improved. BSD City is a new city with an eco-friendly residential concept that has green open space to create a beautiful urban environment. The green open spaces in the BSD City area are in the form of city parks, namely Taman Kota 1 BSD and Taman Kota 2 BSD. This research was conducted in Taman Kota 1 BSD and Taman Kota 2 BSD with an aim of identifying the plants’ types and functions, evaluating the ecological and aesthetic functions of the green open spaces, and providing results in the form of recommendations for plants improvement and arrangement to improve the parks’ comfort and aesthetics. The results showed that the number of plants in Taman Kota 2 BSD was higher than Taman Kota 1 BSD, while the more diverse species were in Taman Kota 1 BSD. The results of the assessment based on plant function in temperature modification and humidity control in Taman Kota 1 BSD and Taman Kota 2 BSD were in the good

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.
