Judul: Evaluasi Fungsi Ekologis Dan Estetika Pada Beberapa Taman Kota Di Jakarta Selatan
Abstrak: Taman kota sebagai salah satu jenis ruang terbuka hijau publik yang memiliki peran penting dalam meningkatkan kualitas lingkungan perkotaan. Dua aspek penting yang perlu dalam taman kota yaitu fungsi ekologis dan estetika. Untuk mengetahui sejauh mana pelaksanaan fungsi ekologis dan estetika, perlu adanya evaluasi menyeluruh dari aspek tersebut. Penelitian ini bertujuan untuk mengidentifikasi vegetasi, mengevaluasi pelaksanaan fungsi ekologis dan estetika, dan untuk mengetahui persepsi serta preferensi pengguna dari lanskap di setiap taman. Penelitian dilaksanakan selama tujuh bulan dan berlokasi di empat taman di Jakarta Selatan, antara lain Taman Ayodya, Taman Martha Tiahahu, Taman Tangkuban Perahu dan Taman Mataram. Metode penelitian ini dibagi menjadi dua metode, evaluasi fungsi ekologis dan evaluasi kualitas estetika di setiap taman. Fungsi ekologis akan dievaluasi dengan membandingkan kondisi yang ada dengan kriteria standar untuk fungsi ekologis, sedangkan kualitas estetika akan dievaluasi dengan menggunakan metode scenic beauty estimation (SBE) serta preferensi pengguna dan persepsi. Hasil penilaian fungsi ekologis, Taman Tangkuban Perahu terbaik dalam fungsi peredam bising dan penahan angin, Taman Ayodya terbaik dalam modifikasi suhu dan Taman Martha Tiahahu terbaik dalam fungsi kontrol kelembaban. Penilaian estetika, Taman Ayodya memiliki kualitas estetika tertinggi dan Taman Tangkuban Perahu memiliki kualitas terendah. Kondisi ekologis yang baik berpengaruh terhadap kondisi estetika taman.

Judul: Analysis of City Parks Ecological Function for Central Jakarta Sustainability
Abstrak: Taman Kota sebagai ruang terbuka hijau, memiliki fungsi ekologis yang berperan dalam mendukung keberlanjutan kota. Jakarta Pusat memiliki beberapa taman kota yang berpotensi mendukung keberlanjutan kota jika berfungsi dengan optimal. Penelitian ini bertujuan menganalisis fungsi ekologis dan persepsi masyarakat terhadap fungsi ekologis di Taman Menteng, Taman Situ Lembang, dan Taman Suropati. Fungsi ekologis dinilai dengan membandingkan kondisi eksisting dengan kriteria yang telah ditetapkan, dan persepsi masyarakat didapatkan melalui kuesioner. Hasil penelitian menunjukkan ketiga taman memiliki fungsi yang berjalan cukup baik, namun masih perlu peningkatan dalam beberapa fungsi. Mayoritas responden menganggap fungsi sudah berjalan baik, namun mengharapkan beberapa fungsi dapat ditingkatkan., City parks, as green open spaces, serve an ecological function that plays a crucial role in supporting urban sustainability. In Central Jakarta, a few city parks have the potential to contribute significantly to the city's sustainability if their ecological functions are optimized. This research aims to analyze the ecological functions and public perceptions regarding these functions in Taman Menteng, Taman Situ Lembang, and Taman Suropati. Ecological functions assessed by comparing the current condition of each tree against established criteria, and public perceptions gathered through questionnaire data. The results indicate that each park is functioning adequately, but there is room for improvement in certain ecological functions. The majority of respondents acknowledge that the functions are performing well; however, they express a desire for some aspects of the functions to be improved.

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.
