Judul: Pemetaan Polutan Udara dan Suhu Permukaan Sebagai Dasar Pertimbangan Pembangunan Ruang Terbuka Hijau di Jakarta Timur
Abstrak: East Jakarta as one of municipality in DKI Jakarta has been rapidity developing particularly in construction sector. Incrase of human needs in terms of residentials, industries, and technologies would give negative impacts to the environment. This research was intended to map air pollutant in East Jakarta, which would provide considerations and recommendation for the goverment in developing green open space (GOS) for improving quality of public convenience. The methods used were Inverse Distance Weighting (IDW) interpolation and supervised classification. The results showed that the highest concentration of pollutant in East Jakarta was Cakung Subdistrict with Total Suspended Particulate (TSP), Nitrogen Dioxide (NO2) concentration was showed in Cakung Sub-district, Duren Sawit, Pulagadung and Kramat Jati. Moreover, the highest concentration of Sulfur Dioxide (SO2)was showed in Cakung Subdictrict, Cipayung Sub-district, Ciracas, Kramat Jati, Pasar Rebo. Heavy metal (Pb) distribution spread evenly in wide area of East Jakarta with concentration ≤0.2 μg/Nm³, while the highest temperature surface was showed in Ciracas Sub-district. The districts that should be the first priority of developing green open space are Cakung Sub-district, Ciracas and the second priority are Sub-district Duren Sawit, Pulogadung, Cipayung, Pasar Rebo, Kramat Jati, Jatinegara, Matraman dan Makasar.

Judul: Penentuan Lokasi Pengembangan Ruang Terbuka Hijau Berdasarkan Sebaran Suhu Permukaan Di Kotamadya Jakarta Barat
Abstrak: Pesatnya pembangunan cenderung mengorbankan bentang alam hijau serta mengabaikan pentingnya Ruang Terbuka Hijau (RTH) bagi kota. Minimnya RTH menyebabkan berkurangnya kemampuan kota dalam menurunkan suhu permukaan. Kotamadya Jakarta Barat merupakan salah satu kotamadya di DKI Jakarta, yang mengelola RTH terendah. Penelitian ini dilakukan untuk menentukan lokasi pengembangan RTH berdasarkan sebaran suhu permukaan dalam upaya mengurangi suhu permukaan dan menciptakan lingkungan yang nyaman dan sehat. Penentuan lokasi pengembangan RTH menggunakan kelas prioritas, dengan pertimbangan sebaran suhu permukaan dan digolongkan menjadi tiga kelas prioritas. Hasil penelitian menunjukkan bahwa kelas prioritas pertama seluas 2 591 ha, kedua seluas 6 961 ha, dan ketiga seluas 3 072 ha. Jumlah luasan RTH di kelas prioritas pertama yang dapat dikembangkan sebesar 20 ha pada RTH pohon dan 54 ha pada RTH non pohon.

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.
