Abstrak: This research take the theme about the role of Informal Leaders in Sustainability process of farmers group. The group here is Farmers sheep groups united that called Mekar Jaya. The frame of this research think that the sustainabilty of Farmers group is influenced by several factors. Those are internal factors of group, The role of informal leaders, afld external factors of group. This research also want to see about The rank or stage of sustainability of group itself. The sample of research is about 79 peoples who is the members of group. The data was collected by using quitiinary and depth interview. The survei has conducted since March until April 2002. Finnaly, the data was analyzed by using Tau-kendall technique to explain correlation among sustainability of group with the factors that can influence it. Sosiometry technique is also using to find the cliques and the leaders in group. The analysis is completed by explaining the development stage of group with planned change method.

Judul: Isolasi dan pemurnian bahan aktif dari mikroalga BTM 11 sebagai inhibitor RNA helikase virus hepatitis C
Abstrak: Hepatitis C virus is the cause of hepatitis C disease which has high virulence. Recent therapy using combination of ribavirin and alpha interferon has short efficiency < 80%. Thus, the discovery of new drug is needed. Antiviral drugs can be discovered through molecular target therapy by finding the inhibitor of RNA helicase that play role in viral replication. Inhibitor can be derived from chemical compound produced by microalgae. The aim of this research was to isolate the active compound from microalgae BTM 11 which had inhibitory activity against RNA helicase. Inhibitory activity was measured by releasing of phospate inorganic in colorimetric ATPase assay. Crude extract was fractionated using gel filtration chromatography with methanol in chloroform solvent. The result showed that Fraction 3 has the highest inhibitory activity which (81.205%). Phytochemical test of crude extract indicated positive flavonoids and coumarin. Thin layer chromatography (TLC) analysis with eluent chloroform: methanol gave 2 spots with Rf value of 0.8 and 0.37. Moreover, high performance liquid chromatography (HPLC) analysis showed absorption peak with the highest abundance at the retention time of 12.483 minute and 16.617 minute was 266 nm and 230 nm. According to these of phytochemical, TLC, and HPLC, inhibitor compound from BTM 11 belongs to flavonoids.
