Abstrak: Mangrove forest has had very imporant rules in our lifr,not only from the ecologic side, but also from the economic side. since Japan colonialism in Indonesia the destruction of mangrove forest in Indonesia had kept on increase up to now, including the destruction in "pantura" way or called North Coast way. The destructtion of mangrove ecosystem not only caused reduction of mangrove area also caused the decrease of its quality. Considering how very important the mangrove forest motivated me to think how to prevent the damage and made the green revolution for the mangrive forest. According to the thought of making green revolution become successful, so it has been developed that this program involved all the citizens around the which called Community Based Forest Management (CBFM) in hooks silvofishery ponds. This research is meant to analyze the using of mangrove forest are financially as a pond area, so we could know that has been occured, which was arranged to combine the ecology and social economic aspect in human life.

Abstrak: Mangrove forest as unique ecosystem supports an important life in coastal area,and has ecological functions as nutrient supplier for its biota, place for spawning and nursery ground, coastal abrasion buffer, protect from hurricane and tsunami, waste absorber, salt water intrusion defender and others. Besides, mangrove forest has high economic values like as wood and herbal produc tions, fisheries catchments etc. Farther, mangrove forest as habitats for various bird, reptile, mammals other and wildlife, it provides a rich biodiversity and genetic pool this supporting life system. Mangrove protects water quality, absorb CO2 and produce O2 higher than other type of forest. Mangrove has high ecological function and economic value that give benefit for local community requirement. To increase and preserve biological and ecological function of mangrove forest need rational approach. Empang parit system provide application alternative of sylvofishery estimaties of economic value needed for managing mangrove forest to give sustainable benefits for its community. Base on calculation and analysis of its which pattern 80% forest and 20% fishpond in Kecamatan Logonkulon, Kabupaten Subang give highest economic result. Its parameter use Return Cost Ratio analysis (R/C), Return of investment, profit and Break Even Point (BEP) Keyword : Mangrove forest, empang parit , analysis of finansial, usahatani,

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
