Judul: Sistem Tenurial dan Sistem Nafkah Masyarakat Adat (Kasus Desa Adat Tenganan Pegringsingan, Kecamatan Manggis, Kabupaten Karangasem, Provinsi Bali).
Abstrak: Hubungan manusia dengan alam erat kaitannya dan dapat dilihat dari pola pewarisan lahan dan sistem tenurial (pemanfaatan dan penguasaan lahan) desa adat yang dapat mempengaruhi sistem nafkah masyarakat adat. Penelitian ini dilakukan di Desa Adat Tenganan Pegringsingan, Kecamatan Manggis, Kabupaten Karangasem, Provinsi Bali. Tujuan dari penelitian ini adalah menganalisis pola pewarisan lahan pada tanah adat, menganalisis sistem tenurial, menganalisis sistem nafkah dan mengidentifikasi pengaruh sistem tenurial terhadap sistem nafkah di Desa Adat Tenganan Pegringsingan, Bali. Hasil dari penelitian ini yaitu sistem tenurial (penguasaan dan pemanfaatan lahan) sepenuhnya diatur secara komunal. Hasil produksi pertanian dengan sistem bagi hasil bersama penggarap menjadi sumber pendapatan utama masyarakat. Dari hal tersebut dapat diketahui bahwa sistem tenurial tidak berubah maka sistem tenurial tidak mempengaruhi sistem nafkah masyarakat adat.

Judul: Sistem Tenurial dan Kearifan Tradisional Masyarakat Adat Baduy dan Hubungannya dengan Sistem Pangan Lokal (Kasus Desa Kanekes, Kecamatan Leuwidamar, Kabupaten Lebak, Provinsi Banten)
Abstrak: Peningkatan jumlah penduduk mengakibatkan semakin tingginya kebutuhan terhadap lahan untuk produksi pangan. Penelitian ini dilakukan pada masyarakat Baduy Desa Kanekes, Kecamatan Leuwidamar, Kabupaten Lebak, Provinsi Banten. Tujuan dari penelitian ini adalah menganalisis sistem tenurial, kearifan lokal dalam sistem pertanian, hubungan sistem tenurial dan kearifan lokal terhadap sistem pangan lokal. Metode yang digunakan dalam penelitian ini adalah pendekatan kuantitatif didukung oleh data kualitatif dan teknik non-probability sampling dalam menentukan responden. Unit analisis dalam penelitian ini adalah rumah tangga dengan jumlah sampel sebanyak 40 responden yang dipilih secara purposive. Hasil penelitian menunjukkan bahwa sistem kepemilikan lahan pada masyarakat Baduy diperoleh melalui pewarisan dan pembelian lahan, sementara sistem penguasaan lahan diperoleh melalui sewa dan bagi hasil. Bentuk budidaya dalam pertanian masyarakat Baduy adalah tanaman campuran dengan pola tanam secara tumpang sari. Hasil panen padi secara budaya tidak boleh diperjualbelikan namun harus disimpan di dalam leuit (lumbung padi). Kearifan lokal berhubungan dengan sistem pangan lokal masyarakat Baduy. Sedangkan sistem tenurial tidak berhubungan dengan sistem pangan lokal masyarakat Baduy., The increase in population has resulted in a higher demand for land. The location of this study was in the Kanekes Village, Leuwidamar District, Lebak Regency, Banten Province. This study aims to determine tenure system, local wisdom in the agricultural system, the effect of tenure system and local wisdom on the local food This study used a quantitative with qualitative approach and used non-probability sampling techniques. The unit of analysis in this study was households with a sample of 40 respondents who were selected purposively. The results showed that the land tenure system in the Baduy community was through inheritance, buying and selling, renting, and profit-sharing. The form of cultivation in Baduy agriculture is mixed crops with an intercropping pattern. Rice yields are culturally not allowed to be traded but must be stored in leuit (rice barns). Local wisdom related to the local food system of the Baduy community. Meanwhile, the tenure system is not related to the local food system of the Baduy community. Keywords: Baduy

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.
