Abstrak: INTRODUCTION.Agroforestry is one of community forest design which is combining forestry and agriculture sector in a solid management. Agroforestry also the name that stands for land use system and technology where solid wood plant (trees, perdu, palm-trees, bamboo, etc) planting together with agriculture crops or animals for distinctive goals. Mixed planting is one of agroforestry construction that traditionally implement by society that also can divided into homegarden and garden. Mixed orchard management that organized by society around Gunung Walat Educational Forest (HPGW) including solid wood plants, fruits plants and agriculture crops. Wood potency with minimum quantity is belief will be a leading factor towards forest sustainability in HPGW. Management system identification and income contribution of farmers from mixed orchard need to ensure as strong consideration from policy that will be taken in order to establish society empowerment around HPGW. METHOD.Research is taken place at Sukadamai Village, Kecamatan Cicantayan, Kabupaten Sukabumi, West Java on April through Mai 2009 with two different plot samplings, which is farmers (35 people) and mixed orchard (4 plots) which grouped according to spacious of mixed orchard. Data is analyzed with qualitative method (data gathering, grouping, farmer’s characteristic identification and income contribution). After that, data is grouped and presented in a tabulation of numbers and images based on gathered data information. RESULTS.According to the research result, custom is the factors for farmers to manage their mixed orchards (31 %), technique of management (6 %), economy (60 %) and ecology (3 %). Mixed orchard management that farmers accomplished are; land management (weeding and land fertilizing); seed foundation; planting; breeding (land cleaning, fertilizing and cleaning of pest/disease); cutting; and marketing. The contribution of mixed orchard is Rp. 6.933.274/year (60,6 %) with the income of solid wood plant is Rp.1.289.464/year (16,3 %). The capital problems of mixed orchard management in Sukadamai Village are economy (70 %), establishment the organization (23 %), security (6 %), and pest/disease attack (1 %). CONCLUSIONS.Organization establishment and forwarding research about strategy to improving farmer’s wood income in Sukadamai Village.

Judul: Kontribusi Pengelolaan Hutan Rakyat Terhadap Pendapatan Rumah Tangga Petani dan Analisis Kelayakan Usaha Hutan Rakyat. (Studi di Desa Babakanreuma, Kecamatan Sindangagung, Kabupaten Kuningan, Propinsi Jawa Barat)
Abstrak: According to Hardjanto (2000), income of community forest farmers in Java are still positioned as a by product and incidental. Range of income is not more than 10 % of total revenue and sought simply. It shows that the contribution of community forest have not become the foundation of households subsistence, so it is necessary to conduct a study about how is the contribution of community forests management to total household income and it’s feasibility, especially in the Village Babakanreuma, District Sindangagung, Kuningan Regency, West Java Province. The purpose of this study was to identify the system of community forests management and marketing, knowing the contributions community forests management to households total income as well as examine the linkage of effectiveness of community forests area to the households total income and to determine the feasibility of it’s businesses. Determination of the respondents conducted using stratified random sampling method in which the respondents were 36 people obtained from the slovin formula. This study uses a qualitative approach that conducted by survey method using questionnaire and supported by quantitative techniques. The results shows that the contribution of community forests management to the households income has been very visible, reinforced by the magnitude of the contribution value that become higher and increasing in strata. So that the farmers land area of community forest significantly affected their household income. From the data obtained, in 1st strata , the resulting contribution is Rp. 2,208,333.00 per year (7.79%), 2nd strata is Rp 3.800.000,00 per year (11.98%), and 3rd strata is Rp 5.500.000,00 per year (13.00%). Management of community forests is feasible to run on all three strata. These statements are based on the amount of NPV (Net Present Value) that is not negative, BCR (Benefit Cost Ratio) is greater than one and the IRR (Internal Rate of Return) is greater than the prevailing rates. NPV values in strata I, II and III is Rp 6.378.880,00; Rp 14.134.803,00 and Rp 3.985.918.00. Community forests management systems at the sites are still modest. The harvesting is still based on needs and not according to the Sengon plant cycle which is the staple in this village. The timber marketing is only done by a contract system or the middleman (tengkulak) / buyer and furthermore become the responsibility of the middleman / buyer it self.

Judul: Pengujian Virus Newcastle Disease Gen VII Isolat Lapang Sebagai Virus Standar Pada Uji Tantang Vaksin
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
