Judul: Systematic Review of Urban Forest in Indonesia 2000 - 2021
Abstrak: Dalam suatu perkotaan, dibutuhkan yang namanya Ruang Terbuka Hijau (RTH). Tujuan penelitian ini adalah menganalisis perkembangan penelitian hutan kota di Indonesia selama 21 tahun dari tahun 2000 – 2021. Alat yang digunakan dalam penelitian ini adalah situs scholar.google.com, perangkat lunak Microsoft Word dan Microsoft Excel. Bahan yang akan digunakan dalam penelitian ini adalah bahan informasi yang tersedia secara online maupun offline berupa jurnal atau prosiding mengenai hutan kota yang berlokasi penelitian di Indonesia dengan menggunakan metode systematic review. Terdapat 116 artikel yang digunakan dalam penelitian. Distribusi artikel terus meningkat, terutama pada periode tahun 2016 – 2021 dengan peningkatan sebanyak 300% dibandingkan dengan periode tahun 2000 – 2015. Artikel terbanyak ditemukan di provinsi Jawa Barat dengan 13 artikel dan artikel tidak dapat ditemukan di Provinsi Bengkulu, Gorontalo, dan beberapa provinsi lainnya. Tema yang ditemukan terbanyak adalah tema fisik dengan 44 artikel dan tersedikit adalah tema valuasi dengan 10 artikel. Sub-tema terbanyak ditemukan adalah biodiversitas dengan 24 artikel dan tidak ditemukannya sub-tema edafik tanah dan Kualitas Air.

Judul: The Development of Community Forest Research in Indonesia: Bibliography Review
Abstrak: Hutan rakyat di Indonesia memiliki peranan penting dalam menyangga keberlangsungan hidup masyarakat. Ilmu pengelolaan hutan rakyat diperlukan dalam mewujudkan pengelolaan hutan yang lestari. Namun, ilmu pengelolaan hutan rakyat masih relatif muda jika dibandingkan dengan ilmu pengelolaan hutan (forest management) yang diperuntukkan guna mengelola hutan-hutan luas dan masif. Oleh karena itu, penting untuk diketahui sejauh mana perkembangan ilmu pengelolaan hutan rakyat yang telah dilakukan melalui berbagai penelitian selama ini. Tujuan penelitian ini adalah memetakan perkembangan penelitian di hutan rakyat dari tahun ke tahun meliputi lokasi penelitian, publikasi, tema, dan subtema mulai dari tahun 2013-2023 serta mengetahui kesesuaian antara teori dan praktik pengelolaan hutan rakyat. Penelitian dilakukan menggunakan tinjauan bibliografi dan dianalisis secara deskriptif kualitatif serta anotasi bibliografi. Hasil penelitian menunjukkan bahwa penelitian hutan rakyat banyak dilakukan di Provinsi Jawa Barat, Kabupaten Bogor, publikasi Jurnal Penelitian Hutan Tanaman, dengan tema produksi dan sub-tema penanaman. Sebagian praktik di lapangan tidak menerapkan teori, sehingga pengelolaan hutan rakyat belum mencapai optimum., Community forests in Indonesia have an essential role in ensuring communities’ survival. The science of community forest management is necessary for achieving sustainable forest management. However, the science of community forest management is still relatively young compared to the forest management sciences intended to manage large and massive forests. Therefore, it is important to know to what extent the development of the science of community forest management has been through various studies over the years. The objective of this research is to map the development of research in the community forests from year to year, covering the location of research, publications, themes, and sub-themes starting from 2013-2023 as well as to find out the correlation between the theory and practice of community forest management. The research was conducted using bibliographic surveys and analyzed qualitatively descriptively, as well as an annotated bibliography. The research results show that a lot of community forest research is done in West Java Province, Bogor District, the publication of the Jurnal Penelitian Hutan Tanaman, with the themes of production and planting sub-themes. Some practices in the field do not apply theory, so community forest management has yet to reach optimum.

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.
