Judul: Dampak Pertambangan Nikel Terhadap Sosial – Ekonomi – Ekologi Masyarakat di Kecamatan Wasile Kabupaten Halmahera Timur
Abstrak: Wasile, one of the East Halmahera district contained nickel mining, and a great influence on the social, economic and environmental life of the community. Thus this study refers to the theory and previous studies, researchers tried to base it on a frame of mind that the Sustainability of social, economic society strongly influenced by; carrying capacity of the environment, natural resources, human resources, facilities and infrastructure, the financial, social and cultural rights. The purpose of this study was to analyze the impact of nickel mining on socio - economic - ecological communities in the sub District Wasile, East Halmahera. The research center is a sample of 2 (two) villages that are near and far away from the mining of nickel, the village of Batu Raja (near the village) and Subaim Desa (village far). By sampling in this study consisted of local people to be around and who are far away from the nickel mining company, yet to feel the impact of the mining question. The number of samples taken from the respondents ie 80 people consisting of 40 people from each village who are near and far away from the mine site consisting of local people actively working. Direct Observation Field Interviews In-depth interviews using questionnaires Change in Productivity analysis or can be referred to as the Productivity method, Chi-square analysis, and SWOT. Based on the results of mining in the region contribute to the local economy are significant in terms of: (a) regional Revenue, (b) Expansion of employment opportunities, (c) Reduction of unemployment in the area.

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.
