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: Analysis of Forest and Peatland Fire  Vulnerability in Muaro Jambi Regency, Jambi Province
Abstrak: Provinsi Jambi dikenal sebagai wilayah yang rentan terhadap kebakaran karena hampir setiap tahun wilayahnya mengalami insiden kebakaran pada lahan gambut yang memiliki luas cukup signifikan. Tujuan dari penelitian ini adalah untuk menganalisis distribusi dan jumlah hotspot, menganalisis korelasi antara curah hujan dengan hotspot sebagai indikator terjadinya kebakaran hutan dan lahan gambut, serta menganalisis kegiatan masyarakat terkait pembakaran hutan dan lahan gambut. Pemetaan sebaran hotspot dilakukan dengan analisis spasial data hotspot, sebaran lahan gambut, dan data administrasi Kabupaten Muaro Jambi. Data sebaran hotspot, dan curah hujan harian yang telah direkapitulasi kemudian dilakukan uji korelasi bivariate pearson menggunakan aplikasi SPSS. Wawancara secara in depth interview dengan jenis teknik sampling kuota yang telah disediakan untuk menentukan kegiatan masyarakat yang dapat memicu kebakaran. Distribusi hotspot di Kabupaten Muaro Jambi selama periode 2019- 2023 mencapai total 5974 titik. Hasil penelitiam menunjukkan bahwa hubungan antara curah hujan dan hotspot di Muaro Jambi tidak signifikan dan berkorelasi negatif yang berkategori sedang dengan nilai P value sebesar 0,493 > 0,05., Jambi Province is known as an area vulnerable to fires because almost every year it experiences fire incidents on peatlands, which have a significant extent. The purpose of this study was to i) analyze the distribution and number of hotspots, ii) analyze the correlation between rainfall and hotspots as indicators of forest and peatland fires, and iii) analyze community activities related to forest and peatland burning. Mapping of hotspot distribution was conducted using spatial analysis of hotspot data, peatland distribution, and administrative data of Muaro Jambi Regency. The distribution of hotspots and daily rainfall data that had been recapitulated were then subjected to bivariate Pearson correlation tests using SPSS software. In-depth interviews with a quota sampling technique were conducted to determine community activities that could trigger fires. The distribution of hotspots in Muaro Jambi Regency during the period 2019-2023 reached a total of 5,974 points.. The analysis shows that the relationship between rainfall and hotspots in Muaro Jambi is not significant and moderately negatively correlated, with a P-value of 0.493 > 0.05

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.
