Judul: Pengembangan Sistem Informasi Tanaman di Kebun Raya Bogor Berbasis Android
Abstrak: Bogor Botanical Gardens (BBG) is the third largest botanical garden in Indonesia. There are 13697 specimens in BBG, which are grouped into 3441 species, 1265 genus, and 220 families in an area of 87 hectares. The absence of an application which can provide information about the plant and its location causing difficulties for users to gain detail information and location of a plant to be visited. The purpose of this research was to build a plant information systems at BBG by integrating geographic information system (GIS) on Android. This system was expected to help users to see detail information of plants and can guide them to the area location they want to visit. The research was conducted in several stages, started with planning, analyzing system requirements, system design, system implementation, and maintenance. The test results shown that the system was able to work well and produce the expected output

Judul: Pembangunan Aplikasi Android Informasi Tumbuhan Berbasis Geospasial di Kebun Raya Bogor
Abstrak: Kebun Raya Bogor merupakan tempat penelitian dan pariwisata edukasi tumbuhan tropis. Papan tumbuhan adalah salah satu fasilitas yang disediakan Kebun Raya Bogor. Papan tumbuhan berfungsi untuk menginformasikan jenis tumbuhan yang dilestarikan. Sedikitnya informasi yang dimuat dan kerusakan pada beberapa papan tumbuhan menyebabkan fungsinya menjadi kurang efisien. Penelitian ini berupaya menghadirkan sebuah solusi atas permasalahan tersebut. Solusi yang diajukan adalah membangun aplikasi informasi tumbuhan pada smarthphone Android. Aplikasi tersebut dapat meningkatkan efisiensi informasi tumbuhan melalui sebuah antarmuka yang ditampilkan. Global positioning system menjadi salah satu teknologi yang dimanfaatkan untuk mendeteksi informasi tumbuhan berbasiskan geospasial. Formula Haversine berfungsi untuk mengkalkulasi jarak dari lokasi relatif tumbuhan terhadap lokasi user saat ini. Pengujian aplikasi pada 2 tipe smartphone yang berbeda memberikan performa yang cukup baik. Persentase rata-rata akurasi tepat mendeteksi sebesar 66% dan 73%. Aplikasi yang telah dibangun mampu mendeteksi posisi dan menampilkan antarmuka informasi tumbuhan yang lebih lengkap.

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.
