Judul: Dampak Pembayaran Jasa Lingkungan Daerah Aliran Sungai Cidanau Terhadap Sosial Ekonomi Masyarakat Desa Citaman, Serang
Abstrak: Payment for environmental services (PES) is a social institution that organizes the relationship between Citaman Village’s farmers as a provider of environmental services, and PT. KTI as the payer of environmental services.The objectives of this study are to analyze the impact of PES on the socio-economic conditions of the Citaman’s farmers, and to analyze benefits that received by the payer of environmental service i.e. PT KTI. The results show that, first, PES creates positive impact to the socio-economic conditions ofCitaman’s farmers, such aspositive engagement of the farmers community to the PJL scheme, active participation of the Forest’s Farmer Group, increase farmer incomes, creates newlivelihood formations,as well asincentives received by the farmers. Second, so far, from the ecological point of view, PES has not able to provide benefits for payer of the environmental servicse, particularly seeing from the water continuation and fluctuation. However, it is expected that the payer could gained the ecological benefits of PES if the schemecould work in a more longer and vast area than present.

Judul: Model skema pembayaran jasa lingkungan dalam pengelolaan daerah aliran sungai (studi kasus di sub DAS Citanduy Hulu dan sub DAS Ciseel)
Abstrak: This study suggests an alternative solution to solve degradation in Subwatershed Citanduy Hulu and Sub-watershed Ciseel using Payment Environmental Services (PES) model. It is an instrument of economic policy based on economic incentives. PES is established between the owner or manager of the land on the upstream with water users both for commercial and non commercial purposes on the middle as well as the downstream. Conditions and characteristics of the watershed are different from one to another, therefore in order to apply PES an appropriate model is required. The purpose of this study is to design a PES model in Sub-watershed Citanduy Hulu and Sub-watershed Ciseel, includes an analysis of the typology of the watershed, watershed characteristics analysis, economic valuation and institutional analysis. The typology of watershed is used to determine which regions are eligible for the implementation of PES. Soil Water Assessment Tool (SWAT) is applied to determine such regions. The analysis showed that there are 7 (seven) Subwatershed in the area of Citanduy watershed, namely: Sub-watershed Citanduy Hulu, Cijolang, Cimuntur, Ciseel, Cikawung, Citanduy Tengah and Citanduy Hilir. Among those sub-watersheds, only Sub-watershed Citanduy Hulu and Subwatershed Ciseel are qualified because of their potential for environmental services, environmental service providers, resource management, and institutional environment. The watershed characteristics is used as the basis for determining the scope of the PES model. From SWAT analysis results in flow of water in the upstream Sub-watershed Citanduy Hulu, which is about 11,4% is the flow of surface (surface flow) and 88.6% lateral and groundwater flow, while in the middle-end of about 5,5% is the surface flow and 94,5% lateral and ground water flow. This condition shows that from the aspect of availability of Sub-watershed Citanduy Hulu currently still in safe condition, both the dry and rainy season. Nevertheless, in order of quantity, quality and continuity of water can remain assured, it is need to rehabilitate the land cover with the erosion rate is relatively moderate and severe area of 1.574 Ha and maintain existing wetland and gardens. For Sub-watershed Ciseel water flow composition in the upper and middledownstream almost equal, is about 46% came from surface flow and 54% of the lateral and groundwater flow. This condition shows that from the aspect of availability of Sub-watershed Ciseel still depends on the season, it is necessary to rehabilitation and conservation of land cover with moderate and severe area of 1.402 Ha and improve wetland and gardens conditions. This indicates that the water catchment area in each unit of land significant role in providing groundwater recharge...dst

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
