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: Transisi Fasa Materi Hadronik ke Materi Kuark pada Inti Bintang Neutron.
Abstrak: Bintang neutron terdiri dari beberapa lapisan yang disusun oleh materi nuklir yang berbeda dengan kerapatan yang semakin tinggi ketika mendekati pusat bintang. Inti luar bintang neutron disusun oleh materi hadronik (nukleon, lepton, dan hyperon), sedangkan inti dalam bintang neutron disusun oleh kuark-kuark bebas (up, down, strange) yang saling berinteraksi. Tujuan penelitian ini adalah mempelajari bagaimana transisi dari inti luar ke inti dalam bintang neutron dengan menggunakan pendekatan RMF (Relativistic Mean Field) untuk materi hadronik dan CIDDM (Confined Isospin Density Dependent Mass) untuk materi kuark. Tekanan transisi diperoleh ketika potensial kimia barion materi hadronik dan materi kuark bernilai sama. Nilai tekanan transisi dengan parameter SU6-TM1 sekitar 87 MeV/fm3 dan diperoleh massa maksimum bintang neutron yaitu 1.92M dengan jari-jari sekitar 8.62 km. Nilai tekanan transisi dengan parameter SU6-G2 sekitar 53 MeV/fm3 dan massa maksimum bintang neutron yaitu 1.88M dengan jari-jari sekitar 8.16 km. Jenis transisi fasa adalah orde satu ditandai dengan diskontinuitas dalam kerapatan energi (adanya mixed phase). Parameter-parameter pada model nuklir yang digunakan menyebabkan perbedaan kekakuan persamaan keadaan (EOS) dari materi hadronik dan materi kuark sehingga nilai tekanan transisi dari fasa hadronik ke fasa kuark juga berbeda.
