Oleh karena itu diperlukan penelitian ini untuk menemukan kendala/permasalahan pada sistem pengadaan tanaman dan memberikan rekomendasi strategis terkait pengadaan tanaman di nurseri agar usaha nurseri dapat berkembang lebih baik dan berkelanjutan. Selain itu, penelitian ini juga bertujuan untuk mempelajari sistem penyewaan tanaman yang dapat menjadi peluang usaha baru dalam bidang tanaman. Penelitian dilaksanakan di Sentra Tanaman Hias Permata Buana Bojongsari, Kota Depok dari Bulan Januari 2023 sampai dengan September 2023. Pengumpulan data dilakukan dengan observasi langsung di lapangan, wawancara dengan pengelola dan studi pustaka. Data dianalisis secara kualitatif dan kuantitatif menggunakan metode analisis SWOT. Hasil penelitian menunjukkan bahwa sistem pengadaan tanaman di Sentra Tanaman Hias Permata Buana yang terdiri atas perbanyakan, pemeliharaan, dan penjualan masih bersifat konvensional, tetapi beberapa nurseri sudah mulai bergeser ke arah modern dimana pada beberapa nurseri sudah memanfaatkan media digital dan kemajuan teknologi. Berdasarkan pendekatan SWOT, sistem pengadaan Sentra Tanaman Hias Permata Buana berada pada kuadran I (Grow and build strategy) sehingga membutuhkan strategi seperti pengembangan penelitian, sosialisasi/edukasi, atau pengembangan usaha kedepannya. Dengan demikian, rekomendasi strategis yang diberikan untuk sistem pengadaan tanaman di Sentra Tanaman Hias Permata Buana ini berfokus untuk pengembangan pada sistem pengadaan tanaman di nurseri yaitu pengembangan upaya promosi melalui media digital, meningkatkan keterampilan sumber daya dan legalitas, dan memperluas target pasar., The landscape industry in Indonesia is growing along with the emergence of various companies engaged in the landscape sector, one of which is a nursery. Permata Buana Ornamental Plant Center is a place with a collection of nurseries that provide various types of plants, not only selling but also selling plants for indoor and outdoor decoration needs. The place is get crowded with both ornamental and landscape plant lovers who are looking for plant companies for landscape needs, so it is necessary to pay attention to the procurement of plants in nurseries. Therefore, this research is needed to find constraints/problems in the plant procurement system and provide strategic recommendations related to plant procurement in nurseries so that nursery businesses can develop better and sustainably. In addition, this research also aims to study the plant rental system which can be a new business opportunity in the field of plants. The research was conducted at the Sentra Tanaman Hias Permata Buana Bojongsari, Depok from January 2023 to September 2023. Data collection was carried out by direct field observation, interviews with managers and literature study. Data were analyzed qualitatively and quantitatively using the SWOT analysis method. The results showed that the plant procurement system at the Permata Buana Ornamental Plant Center which consisted of propagation, maintenance, and sales was still conventional, but several nurseries had started to move towards modernity

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.
