Judul: Klasifikasi Ruang Terbuka Hijau Wilayah Jakarta Menggunakan Citra Satelit ALOS PALSAR
Abstrak: The development of human civilization and the modern technological advances led to a variety of benefits, whether they are positive or negative. One of the negative aspects is the problem of urban development. Urban development has a negative impact on several aspects, including environmental aspects. There is a need of space to accommodate population and their activities make greenery open space tend to be converted into built space. In general, urban greenery space consists of herbs, plants, and vegetation (both endemic and introduced) to support the benefits of ecological, socio-cultural, as well as architectural. This thesis discusses an application of single polarized ALOS PALSAR Fine mode (FBS) imagery to identify green open spaces in Jakarta. Specifically, this research studied the separation between classes of water bodies, built space, woody greenery open space, and non-woody greenery open space using the L-band. In this study, classification of greenery open space was performed using decision tree method on tonal data. The results suggested that ALOS PALSAR has the capability to give a fairly good classification result on greenery open space mapping in Jakarta area; nonetheless, some objects could not be perfectly classified because of the specification of the data used in this research.

Judul: Kesesuaian Klasifikasi Ruang Terbuka Hijau menggunakan Citra Landsat ETM+ dengan RTRW Provinsi DKI Jakarta
Abstrak: Jakarta Provincial Government determine that the proportion of green open space is as much as 30% Jakarta Province land area. It is stated in The Regional Spatial Plan of Jakarta that was enacted in 2012 and prevail to 2030. The objectives of this research are to analyze the results of land cover classification changes using Landsat ETM + imagery in Jakarta Province, and to compare the classification result toward the green open space area in The Regional Spatial Plan of Jakarta between 2000 and 2012. The result showed that land cover changes in Jakarta mostly happens on the green open space area, which declined by 16.3%. Land suitability analysis of green open space that set out in the Regional Spatial Plan of Jakarta compared to the classification results showed that the proportion of Jakarta green open space in 2000 reached 36%, while for 2004 and 2012 the precentage of green open space as much as 27.5% and 25.5% , this results is not in accordance with the standard of green open space in Jakarta Regional Spatial Plan described in DKI Jakarta Provincial Regulation No. 1 of 2012, that is equal to 37.8%

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.
