Judul: Pengelolaan Ekosistem Mangrove Berbasis Co-Management di Desa Pasarbanggi, Kabupaten Rembang, Jawa
Abstrak: Mangrove merupakan salah satu ekosistem penting pesisir yang memiliki berbagai manfaat dan pemanfaatannya dilakukan oleh berbagai pemangku kepentingan. Penelitian ini bertujuan untuk 1) mengetahui dan menganalisis kondisi sumber daya mangrove dan masyarakat pemanfaat,2) menganalisis peran dan fungsi setiap pemangku kepentingan, serta 3) mengetahui dan menganalisis bentuk co-management terhadap pengelolaan ekosistem mangrove Desa Pasarbanggi, Kabupaten Rembang. Pengambilan data vegetasi mangrove dilakukan dengan menggunakan metode transek kuadrat; sedangkan pengambilan data sosial ekonomi, kelembagaan, dan wawancara dengan metode survei dan purposive sampling. Data yang diperoleh dari vegetasi mangrove meliputi kerapatan, frekuensi, penutupan, dan indeks nilai penting mangrove. Analisis pemangku kepentingan dengan menggunakan matriks kepentingan dan pengaruh. Penelitian menunjukkan terdapat 5 jenis mangrove di Desa Pasarbanggi yaitu Avicennia marina, Rhizophora mucronata, Rhizophora apiculata, Rhizophora stylosa dan Sonneratia alba. Strategi dalam rangka perluasan hutan mangrove yaitu dengan jenis-jenis tersebut. Analisis stakeholder mengidentifikasi 16 pemangku kepentingan yang diklasifikasi dalam 4 grup yaitu subject, key players, crowd, dan by standers. Pengelolaan mangrove di Desa Pasarbanggi masih dalam tahap konsultatif. Untuk meningkatkan efektifitas, pengelolaan diarahkan pada tingkat kooperatif dalam spektrum co-management dengan strategi manajemen.

Judul: Cadangan Karbon Tegakan Mangrove di Desa Pasar Banggi Kabupaten Rembang, Jawa Tengah
Abstrak: Mangroves are usually used as a prevention of coastal erosion and the fish farming (ponds). Ecologically mangrove has potential as carbon stocks. Mangroves that located in Pasar Banggi Village Rembang Regencyhave a function as conservation area. There are four types of mangroves such as Rhizophora mucronata, Rhizophora apiculata, Sonneratia alba, and Avicennia marina. The purposes of this study are to calculate the biomass,the carbon stocks and CO2 sequestration estimation using per tree method and midpoint diameter calculation method. The result showed that the value of the biomass, carbon stocks, and CO2 sequestration consecutively are 81.274 ton/ha, 38.199 ton/ha, dan 140.190 ton/ha. The use of midpoint diameter calculation method can not be applied to find out the value of the biomass, carbon stocks, and CO2 sequestration in mangrove of Pasar Banggi Village Rembang Regency because it has a significant difference.

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.
