Abstrak: Wilayah pesisir merupakan pusat berbagai kegiatan, seperti permukiman, pertambakan, tempat rekreasi, sarana perhubungan dan lain sebagainya. Namun, kegiatan-kegiatan tersebut juga mengancam kelangsungan hidup organismeorganisme laut dm juga memsak lingkungan. Masalah lingkungan yang secara langsung maupun tidak langsung dipengaruhi oleh kegiatan manusia antara lain ada1ah perubahan garis pantai, dimana pembahannya disebabkan dua peristiwa penting, yaitu akresi dan abrasi.

Judul: Perubahan Penutupan/Penggunaan Lahan Dan Perubahan Garis Pantai Di Das Cipunagara Dan Sekitarnya, Jawa Barat
Abstrak: Monitoring the dynamics of shoreline change can be examined from year to year using remote sensing data. Shoreline changes can occur due to natural factors and human intervention such as land use changes. The existence of population pressure on land to supply their needs will lead to changes in land use. The purpose of this research are: (a) to analyze land use changes in watershed in 1972, 1990, and 2008, (b) analyze the physical factors affecting land use change, and (c) analyzing shoreline changes in watershed Cipunagara and surrounding in 1972, 1990, and 2008. Land cover / land use increased during the periods 1972-1990 and 1990- 2008 are the settlements, each covering an area of 1.3% and 5.3%, shrub forest (2.7% and 1.2%), paddy fields (0.3% and 0.5%), and pond (0.9% and 0.2%). A very large decline in the two periods occurred in mixture garden (17.4% and 0.1%), garden teak (4.1% and 0.5%), and mangrove (0.3% and 0.4%). Land use changes were analyzed using binomial logit. Based on the results of the analysis note that the factors that allegedly increase the chances of forest land use change to agriculture are (1) slope (0-8%, 8-15% and 15-25%), (2) elevation 25-100 masl, (3) rainfall 76,47 mm / month and 287,88 mm / month, and (4) soil alluvial, andosol, and podzolik, and (5) geologic parent material with sand, claystone, and lava. Many paddy fields are in areas with geological formations and relatively fertile soils and flat and sloping cycle and the corresponding rainfall. Meanwhile the factors influencing changes in land use from agricultural to settlements are slope (0-8% and 8-15%) and elevation (0-25 masl, 100-250 masl, and 500-1000 masl). There are many settlements on the land is relatively flat, slight, and steep. This shows that the state of the steep slope is no longer a limiting factor to build settlements. The coastline north coastal areas prone Subang addition and reduction. The coastline which tends to grow forward from 1972 to 2008 is in the western part (District Blanakan) and in the delta (Cape Cipunagara). On the Cape and the Cape Pancerwetan Pamanukan tend to grow back because the process of abrasion.

Judul: Evaluation of Influenza Antibody Titers in Serum and Egg Yolk of Layers Vaccinated with Influenza Vaccines.
Abstrak: Influenza belongs to the Orthomyxoviridae family which causes upper and lower respiratory tract infection. The aim of this study was to evaluate influenza-A specific antibody titers from serum and egg yolk of hens vaccinated with quadrivalent influenza vaccines. Three Hy-line Brown layers were vaccinated with quadrivalent influenza type A and B inactivated vaccines. Vaccination was carried out three times at a dose of 0.25 ml/chicken via the intramuscular route. The first vaccination was carried out at 24 weeks of age, then boosters were performed at 28 and 32 weeks of age. Serum and egg yolk were collected every week for 20 weeks since the first vaccination. Influenza A H3N2 and H1N1 antibody titers were determined using hemagglutination-inhibition (HI) test and agar-gel-precipitation (AGP) test. Influenza-A H3N2 and H1N1 specific antibodies were detected in both serum and egg yolk from the first to twenty weeks after the initial vaccination. Highest HI geometric mean titer (GMT) of H1N1 antibody reached 26.67 HIU at nine weeks post first vaccination (p.f.v), while H3N2 antibody reached 26 HIU at six weeks p.f.v. Our result showed that influenza antibodies can be produced in layers using quadrivalent vaccines and layer chickens are able to produce equivalent antibody levels for each influenza subtype.
