Judul: Prioritas Pengembangan Hutan Kota di Jakarta Selatan
Abstrak: South Jakarta is one of the densely populated municipality in DKI Jakarta. Increased urbanization causes degraded lands green space that will lead to environmental degradation such as air pollution and rising temperatures. Urban forest is one of green space that is capable of restoring the balance and healthy urban environment. Criteria in the selection of priority areas using the variable surface temperature and air pollutants and classified by three classes of priority. Urban forest priority location is the availability of green space that goes into the priority class . The results of this study indicate priority areas in the first class of 1269.86 ha ( 8.72 % ) , the second class of 7076.55 ha ( 48.61 % ) and the third class of 6210.03 ha ( 42.66 % ) . The availability of green space that was in the first priority class of 77.96 Ha , the second class of 327.57 Ha and class of 983.61 Ha . Total green space can not be found to reach 10 % of the South Jakarta areas because land limitation and convertion land use.

Judul: Prioritas Pengembangan Ruang Terbuka Hijau berdasarkan Perubahan Distribusi Suhu Udara di DKI Jakarta
Abstrak: Permasalahan lingkungan yang dihadapi oleh DKI Jakarta salah satunya disebabkan oleh menurunnya kualitas Ruang Terbuka Hijau (RTH). Hutan kota sebagai salah satu bentuk ruang terbuka hijau berperan dalam ameliorasi iklim mikro. Hutan kota dapat menurunkan suhu permukaan. Suhu permukaan memiliki keterkaitan dengan suhu udara sehingga dapat digunakan untuk menduga nilai suhu udara. Hutan kota menyerap panas dan menurunkan suhu udara melalui mekanisme transpirasi. Selama tahun 2001-2014 pepohonan di Jakarta mengalami penurunan luasan sekitar 5.1% sementara lahan terbangun meningkat sekitar 13%. Keadaan ini mengakibatkan suhu permukaan meningkat 2-4 °C sedangkan suhu udara meningkat 2-3 °C. Prioritas pengembangan ruang terbuka hijau dalam bentuk hutan kota tidak hanya dilakukan pada lahan-lahan publik tetapi juga dilakukan pada lahan-lahan privat.

Judul: Mud Crab’s (Scylla serrata Forskal 1775) Response to Different Decaying Level of Gold Snail (Pomacea canaliculata Lamarck 1822) Bait.
Abstrak: Mud crab is well known as omnivorous-vigorous-voracious-opportunistic-scavenger. These intertidal animals applies mainly chemoreception in their predatory behaviour. It has been commonly assumed that non fresh gold snail bait is better than fresh bait in stimulating the mud crab. This research's aim is to analyze mud crab response to different decaying level of gold snail bait. Their response were observed as time required to touch the bait and pattern and direction of the mud crab in approaching the baits. The different decaying level of gold snail baits were shown on Total Volatile Base Nitrogen (TVBN) as 16.3 mg/100g (0 day); 534.1 mg/100g (3 days); and 887.4 mg/100g (6 days). The research was conducted from July 2009 until February 2011. The TVBN test for gold snail baits were conducted at Laboratory of BBPPHP Jakarta. The experiment was conducted in Pemalang. The result showed that the average period of mud crabs to touch the baits were 52.14 minutes; 61.57 minutes and 52.57 minutes. Anova test concluded no sufficient evidence of significant effect of TVBN content of gold snail bait on mud crab’s feeding behaviour. Movement pattern B, i.e. left and right deviation followed by straight forward movement to the bait, was commonly exhibited by the crabs. Consequences of time period required by the mud crab to approach the bait on fishing operation is discussed.
