Judul: Conflict analysis of landuse in coastal area (case study in coastal north Jakarta)
Abstrak: Penelitian ini dimotivasi oleh pertanyaan yang tidak pernah berakhir mengenai konflik pemanfaatan lahan wilayah pesisir khususnya di Indonesia dan umumnya Negara-negara berkembang. Squatter yang merupakan kelompok masyarakat yang tinggal di daerah kumuh, pada umumnya mendapatkan tekanan psikologi seperti intimidasi, terror, kekerasan, penculikan, penggusuran dan jarang terjadi penyelesaian terbaik dari pihak-pihak yang terkait untuk menyelesaikan konflik pemanfaatan lahan. Hasilnya baik squatter maupun pemilik lahan tidak mendapatkan manfaat sama sekali dan mereka mengeluarkan biaya yang terlalu tinggi untuk memaksakan kepentingannya masing-masing. Kondisi tersebut dapat menurunkan produktivitas ekonominya dan implikasinya adalah kinerja ekonomi kawasan pesisir menurun.

Judul: Optimizing of use of land for economic development and natural resources conservation in coastal area Sidoarjo Regency East Java
Abstrak: Kabupaten Sidoarjo memiliki luas 71 424,25 ha sepertiganya merupakan kawasan pesisir yang kaya akan hasil-hasil perikanan dan dapat menjadi sumber penghidupan bagi 3 257 KK petani tambak dan 3 282 KK nelayan pencari ikan. Beragam aktivitas yang dilakukan masyarakat meliputi : usaha udang intensif, udang organik, usaha garam, konservasi hutan mangrove, pencari kayu bakar dan remis, serta pemerintah berkepentingan melakukan penatagunaan lahan. Tiap-tiap pelaku ekonomi memiliki kriteria dan tujuan masing-masing, belum ada perencanaan dan pengelolaan secara terintegrasi. Padahal fenomena ini memperlihatkan hubungan yang kurang menguntungkan. Permasalahannya adalah : bagaimana menyusun suatu rencana penggunaan lahan yang dapat mengkompromikan berbagai kepentingan masyarakat dan dapat menunjang hasilhasil ekonomi tanpa merusak lingkungan? Penelitian ini bertujuan : (1) menentukan alokasi penggunaan lahan yang mampu mengkompromikan berbagai kepentingan masyarakat, (2) mencari alternatif strategi penggunaan lahan yang paling baik untuk diterapkan di Pesis ir Kabupaten Sidoarjo, dan (3) melakukan kajian terhadap kemungkinan konsep rencana penggunaan lahan dapat diterapkan atau tidak., Sidoarjo regency has an area of 71424.25 ha. One third of it is coastal area rich in fish production as source of living for 3257 fish farmers and 3282 fishermen along the seashore. There are many various activities done by the community, i.e., running intensive shrimp ponds, organic shrimp ponds, salt business, mangrove forest conservation, fuel wood seller and molusca. Meanwhile, government has an interest in managing the land use. Up to now, there is no integrated planning and management as so each businessman has its own criteria and individual goal in doing their business. This Phenomenon resulted in conflict of using the land. The questions are “How can the plan of land use that compromise many various local interest and trigger the development of local economy without destructing natural environment be arranged?”.

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.
