Judul: Analisis Ruang Terbuka Hijau dan Kecukupannya di Kota Depok
Abstrak: Greenery open space (GOS) is a vegetated open space in urban areas, which its existence is often sacrificed in city development process. This study aims to determine acreage of GOS changes in Depok, to analyze the adequacy of GOS based on population, to identify level of development of the city, to analyze relationship between GOS changes and level of city development, and to identify factors affecting GOS changes. The results showed that in 2006 the GOS in Depok city was 2359.20 ha and 1729.53 ha in 2011 or it was a decline at about 629,67 ha during the period. Based on population number, Depok required 3.627,23 ha of GOS. Scalogram analysis indicated an increase in hierarchy of some subdistricts to level II and level I, and reducing of level III. The greatest changes of GOS occurred in the lower level of hierarchy (Level-III). This is due to limited land available for construction of facilities that are often sacrificed GOS. Determinants factors of GOS changes consisted of positive determinant, including acreage of vacant land, and negative factors, i.e. area allocated for built up in the regional spatial plan and initial acreage of GOS (2006).

Judul: Analisis Ruang Terbuka Hijau Kota Depok Dengan Pendekatan Model Konservasi Air Melalui Sistem Informasi Geografis
Abstrak: Penurunan kualitas dan kuantitas Ruang Terbuka Hijau (RTH) berkaitan erat dengan kegiatan perubahan penggunaan lahan dari kawasan bervegetasi menjadi kawasan terbangun. Kota Depok memiliki RTH privat sebesar 40,68% dan RTH publik sebesar 9,32% (Bappeda, 2007). RTH privat telah melampaui standar 10%, sedangkan RTH publik masih lebih kecil dari standar 20%. Namun demikian, hal ini telah sesuai dengan UU RI No. 26 tahun 2007 dimana RTH minimal 30% dari luas wilayah. Permasalahan yang ada pada Kota Depok adalah banjir yang terjadi di beberapa Kecamatan di Kota Depok, yaitu Kecamatan Cimanggis dan Sukmajaya. Hal ini mungkin disebabkan penempatan RTH yang tidak merata penyebarannya. Tujuan dari penelitian ini adalah menganalisis RTH Kota Depok dengan pendekatan model konservasi air dengan beberapa parameter (kelas lereng, curah hujan, jenis geologi, jenis tanah dan penggunaan lahan), membuat zona kawasan konservasi air untuk menentukan RTH Kota Depok, Rekomendasi Penggunaan Lahan berdasarkan Konservasi Air dan menganalisis hubungan antara tingkat konservasi air dengan RTH.

Judul: Mitochondrial DNA Gene Organization and Phylogenetic Relationship of Naja siamensis
Abstrak: Naja siamensis is one of Asiatic cobra in the Family of Elapidae, known as a cryptic snake. It has many morphological variations that lead to misidentification. Misidentification can cause the wrong concept in developing antivenom types due to high snakebite cases occur in Thailand. Thus, an accurate species identification using a molecular approach is crucially required. Mitochondrial DNA has been used widely in snake molecular studies. These studies were aimed to determine the arrangement of the N. siamensis partial mitochondrial genes using reptile-oriented primers and to reveal the phylogenetic relationship among other species of Asian cobra. DNA extraction was carried out based on the standard DNA salting-out protocol and was conducted by bioinformatics analysis using BLASTn and MEGA 6 software. Gene annotation was performed against N. kaouthia complete genome. A total of 3121 bp of N. siamensis mtDNA genes were sequenced consisting of partial of six regions: 16S rRNA, ND1, tRNA-Ile, CRII region, tRNA-Leu, tRNA-Gln, and COI genes. The mtDNA gene organization of N. siamensis was predicted to has a similar pattern with the common Elapidae mtDNA gene organization. This study showed that there is a monophyletic form in Naja genus and N. kaouthia is the closest species with N. siamensis based on partial 16S rRNA and ND1 gene.
