Abstrak: Perubahan pola penguasaan lahan merupakan perubahan kepemilikan atau hak seseorang atas sebidang lahan. Ada dua jenis penguasaan lahan yaitu milik dan non milik seperti sewa, bagi hasil, gadai, dan lainnya. Perubahan pola penguasaan lahan tersebut disebabkan oleh beberapa faktor salah satunya adalah konversi lahan yaitu perubahan penggunaan lahan pertanian ke non-pertanian. Hal tersebut membuat luas lahan petani penggarap menyusut atau bahkan habis sehingga membuat mata pencaharian mereka bergeser dan berdampak pada kesejahteraan rumah tangga petani. Penelitian ini bertujuan untuk menganalisis dampak yang terjadi pada rumah tangga petani akibat perubahan pola penguasaan lahan dan pergeseran mata pencarharian. Sampel yang diambil sebanyak 24 orang dengan metode sampel jenuh dan sampel bola salju pada petani penggarap yang lahannya tergusur akibat pembangunan perumahan di Desa Ciburuy.

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
