Judul: Kajian tekno ekonomi kapal gillnet material kayu diKarangantu Kabupaten Serang Propinsi Banten
Abstrak: Dalam penelitian ini permasalahan yang ingin dipecahkan adalah pengrajin kapal diupayakan mampu untuk membuat analisa tekno-ekonomi didalam prosedur pembangunan kapalnya. Analisa tekno-ekonomi kapal yang dilakukan dilihat mulai dari awal kegiatan pembangunan kapal sampai proses penurunan kapal ke perairan. Penelitian ini bertujuan untuk mengevaluasi dan menganalisa teknik pembangunan kapal serta perhitungan biaya investasi dan biaya operasional pembangunan kepal gillnet yang dibangun di galangan kapal ikan tradisional Karangantu-Serang. Penelitian ini dilakukan dalam dua tahap yaitu tahap pengumpulan data dan tahap analisa data. Jenis data, cara pengumpulan data dan analisa data disesuaikan dengan pencapaian tujuan penelitian.

Judul: Development Analysis on Gillnet Fisheries in Karangantu Waters, Serang District - Banten Province
Abstrak: Research on gillnet fisheries in Karangantu waters of Serang District has been conducted from November 2005 to April 2006. This research was aimed to : 1) Identifying factors influencing the gillnet productivity, 2) Analysing economic performance of the gillnet fisheries and 3) Formulating alternative policies on gillnet fisheries development in the area. Data collecting was carried out trought purposive sampling of respondents, interviewing by using prepared questionnares, with using descriptive and survey method. Cobb-Douglas ( Soekartawi, 1999) method was used to determine the factors influencing the gillnet productivity. SWOT analysis ( Mulyono, 1996) and Analytical Hierarchy Process, AHP ( Saaty, 1993) were used for the formulation of the policies. Result of the research shows that from seven independent factors, the net size was indicated to be the most factors influencing the gillnet fisheries productivity. The production model of Cobb-Douglas was Y=0,31-0,041X1+0,78X2+0173X3- 0,0453+0,057X5+0,83X6-0,472X7 with its accuracy data 95% and determinant factor 83,3%. Gillnet fisheries in Karangantu is most dominantly used and show profitable performance (BEP Rp.10.915.000,-/year at the production volume of 4.461 kg/year, net B/C value 1,54, NPV Rp. 54.738.293,- and IRR 74,49%). The earnings of gillnet fishers is above Serang District regional minimum wage rate (2005). The following development strategies were recommended: 1) Controlling the number of fishing gear and fishing effort, 2) Arrangement and controlling the fishing ground (DPI) based on fishing gear and increasing the security assurance, 3) Skill improvement for the gillnet fishers, providing capital investment and marketing, 4) Increasing the size of fishing boat and gillnet size, accurate and timely statistic data are desperately needed.

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.
