Abstrak: Forest could give valuable tangible and intangible benefits. But now, there are many unproductive and critical land as the result of land management without considering conservation aspect and the increase of population that pressure the forest. On the other hand, timber supply from natural forests is not enough to fulfill human demands. One of the alternative for solving those problem is community forest development. Objective of this study was to identify the technique of management that has been implemented in community forest and to analyse the influence of community forest to the income of forest farmer households. The selection of respondents was carried out using purposive sampling method, consisted of community forest farmers. Furthermore, selected samples were stratified based on the extent of land area, therefore it was found area of land ownership of strata I < 0,21 hectare, strata II 0,21 – 0,58 hectare and strata III > 0,58 hectare. Total respondents for strata I, strata II, and strata III were 8 respondents, 12 respondents, and 4 respondents respectively. Results of the study showed that total income of agriculture activities of strata I, strata II, and strata III were Rp 15.509.840/year, Rp 15.928.611/ year, and Rp 30.394.792/ year. For income from community forest of agroforestry system, for strata I, strata II, and strata III were Rp 9.588.194/year (61,82%), Rp 9.206.944/ year (57,80%), and Rp 17.966.667/ year (59,11%). Meanwhile from wood product only, the income was Rp 1.477.778/year (9,53%), Rp 2.266.667/ year (14,23%), and 2.216.667/ year (7,29%).

Abstrak: This study was conducted to determine the standard of Newcastle disease virus Gene VII field isolate as a virus challenge to vaccine test. A virus suspension that has previously been tested by HA test then titrated with EID50 using 30 Specific Pathogen Free (SPF) of 10 day old chicken embryonated eggs. In addition, chicken lethal dose50 (CLD50) test were used to determine the virus titer that could cause 50% death of the chicken population. The CLD50 test was used 25 day-old-chickens (DOC) divided into 5 groups. The virus was diluted from 10-1 to 10-8. The 104 to 10-8 dilution of NDV was infected to every group of chicken via eyedrop and intranasal with 0.1 ml/chicken dosage. Haemagglutination test showed that the allantoic fluid were contain high titers of NDV is 512 HAU. The infective NDV that had been titrated by EID50 test showed the virus titers is 109 EID50/0.1 ml or 1010 EID50/ml and the virus titers of CLD50 test e.i 106.48 CLD50/0.1 ml or 107.48 CLD50/ml. These results can be concluded that the NDV Gene VII field isolates were most appropriate to be used as a standard virus to vaccine test
