Abstrak: Agroforestry is a land use system which combines woody plants with agricultural crops. Various previous researches concluded that agroforestry can improve the household income of farmers. Sukaluyu Village became one of the villages that make agroforestry as a source of their economy. The research was conducted to provide information regarding the contribution of agroforestry management to the farmer households as well as information about the agroforestry system adopted by local farmers. The results of research showed that farmers implement agroforestry system who combined trees with crops and trees with medicinal plants in which land management with agroforestry systems contribute to farmer household income was 68.60%.

Judul: Contribution of Agroforestry Community Forests to Farmer's Income in Argapura Village Cigudeg District Bogor Regency.
Abstrak: Kontribusi Hutan Rakyat Agroforestri terhadap Pendapatan Petani di Desa Argapura Kecamatan Cigudeg Kabupaten Bogor. Dibimbing oleh Leti Sundawati. Hutan rakyat agroforestri memiliki manfaat secara ekologi, ekonomi dan sosial. Desa Argapura merupakan salah satu desa di Kecamatan Cigudeg yang memiliki lahan agroforestri yang besar. Penelitian ini bertujuan untuk menghitung kontribusi pendapatan petani dari hutan rakyat agroforestri dan menganalisis karakteristik petani yang memengaruhi pendapatan petani dari sistem agroforestri agar mencapai kesejahteraan petani. Pengambilan data dilakukan melalui wawancara terhadap 30 responden yang dipilih secara convinience sampling. Hasil penelitian menunjukkan bahwa kontribusi hutan rakyat agroforestri sebesar 77,3%. Pendapatan petani lebih besar daripada pengeluaran petani. Namun, setelah dilakukan analisis tingkat kesejahteraan petani, melalui batas garis kemiskinan UMR Kabupaten Bogor 2024, sebanyak 66,7% petani mempunyai pendapatan agroforestri dibawah batas garis kemiskinan dan sebanyak 13,3% petani berada di bawah batas garis kemiskinan berdasarkan garis kemiskinan Kabupaten Bogor. Karakteristik petani yang memengaruhi pendapatan menurut korelasi rank spearman yaitu usia, lama bertani, luas kepemilikan lahan dan pendidikan. Semakin besar nilai korelasi koefisien semakin besar juga pengaruhnya kepada pendapatan agroforestri. Kata kunci: Agroforestri, kayu, kesejahteraan, kontribusi, pendapatan, Contribution of Agroforestry Community Forests to Farmers' Income in Argapura Village Cigudeg District Bogor Regency. Supervised by Leti Sundawati. Agroforestry community forests have ecological, economic, and social benefits. Argapura Village is one of the villages in Cigudeg District, which has a large agroforestry area. The research aims to calculate the contribution of farmers' income from agroforestry community forests and analyze farmer characteristics that influence farmer income from agroforestry systems to achieve farmer welfare. Data collection was carried out through interviews with 30 respondents selected using convenience samplingThe research results show that the contribution of agroforestri community forests is 77.3%. Farmers' income is higher significant than farmers' expenses. However, after analyzing the level of welfare of farmers after analyzing the level of welfare of farmers based on the 2024 Bogor Regency UMR poverty line, 66.7% of farmers have agroforestry income below the poverty line, and 13.3% of farmers are below the poverty line based on the poverty line. Poverty in Bogor Regency. Farmer characteristics can affect income according to Spearman's rank correlation are age, years of farming, size of land ownership and education.. The greater the correlation coefficient value impact to agroforestry income. Keywords: Agroforestry, contribution, income, timber, welfare

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.
