Judul: Community Behavior and Perceptions of Peat Fires in Tangkit Baru Village Jambi Province
Abstrak: Kabupaten Muaro Jambi yang memiliki sebaran gambut seluas 229.703.90 ha kerap kali mengalami kebakaran hutan dan lahan khususnya di Desa Tangkit Baru Kecamatan Sungai Gelam yang sebagian besar daerahnya merupakan lahan gambut. Penelitian bertujuan menganalisis perilaku masyarakat yang dapat memicu terjadinya kebakaran gambut dan menganalisis persepsi dan tingkat pengetahuan masyarakat terhadap pengendalian kebakaran gambut di Desa Tangkit Baru. Analisis data penelitian dilakukan secara deskriptif melalui wawancara menggunakan kuisioner yang berisi 20 pernyataan positif mengenai pengelolaan lahan gambut yang berkelanjutan, dampak dari kebakaran gambut, serta langkah pengendalian kebakaran gambut dari partisipasi masyarakat menggunakan skala likert. Hasil analisis perilaku masyarakat yang dapat memicu terjadinya kebakaran gambut pada lokasi penelitian di lahan gambut merupakan kegiatan sonor, pembersihan lahan dengan pembakaran, dan membakar sampah. Persepsi dan tingkat pengetahuan masyarakat terhadap pengendalian kebakaran gambut termasuk dalam kategori tinggi dan memiliki korelasi hubungan yang sangat kuat. Hubungan antara pengetahuan dan persepsi masyarakat di Desa Tangkit Baru memiliki korelasi positif., Muaro Jambi Regency, which has a peat distribution area of 229,703.90 ha, often experiences forest and land fires, especially in Tangkit Baru Village, Sungai Gelam District, where most of the area is peatland. The research aims to analyze community behavior that can trigger peat fires and analyze community perceptions and level of knowledge regarding peat fire control in Tangkit Baru Village. Research data analysis was carried out descriptively through interviews using a questionnaire containing 20 positive statements regarding sustainable peatland management, the impact of peat fires, as well as steps to control peat fires from community participation using a Likert scale. The results of the analysis of community behavior that can trigger peat fires at research locations on peatlands are sonor activities, land clearing by burning, and burning rubbish. The community's perception and level of knowledge regarding peat fire control is in the high category and has a very strong correlation. The relationship between knowledge and community perception in Tangkit Baru Village has a positive correlation.

Judul: Fire Forest and Land  Control by Community in Pematang Rahim Village, Jambi Province
Abstrak: Lahan gambut merupakan lahan yang kaya akan karbon organik. Oleh karena itu, tanah gambut yang mengering akan menjadi bahan bakar apabila tersulut api. Penelitian ini bertujuan mengidentifikasi dan mendeskripsi penyebab, upaya pengendalian kebakaran hutan dan lahan, dan pemanfaatan lahan oleh masyarakat di Desa Pematang Rahim, Provinsi Jambi. Penelitian ini menggunakan pendekatan kualitatif dengan metode pengambilan data wawancara, observasi, dan studi arsip. Penentuan responden menggunakan metode snowball sampling. Analisis data dilakukan secara deskriptif kualitatif. Hasil menunjukkan penyebab kebakaran lahan di Desa Pematang Rahim disebabkan oleh pembukaan lahan dan kelalaian manusia. Mitigasi kebakaran yang dilakukan seperti patroli dan sosialisasi, pembentukkan Masyarakat Peduli Api (MPA), dan pembuatan papan larangan pembakaran. Pemadaman kebakaran dilakukan secara langsung menggunakan alat pemadam dan helikopter. Pemanfaatan lahan di Desa Pematang Rahim antara lain kebun sawit, kebun pinang, budidaya lebah, dan budidaya burung walet.

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.
