Judul: Prioritas Pengembangan Hutan Kota berdasarkan Distribusi Suhu Udara di Kota Payakumbuh
Abstrak: Hutan kota merupakan salah satu Ruang Terbuka Hijau (RTH) yang memiliki peranan dalam ameliorasi iklim mikro. Hutan kota merupakan suatu konsep yang dipercaya mampu untuk mengembalikan atau menstabilkan kondisi kenyamanan lingkungan perkotaan. Tujuan penelitian ini adalah memetakan prioritas pengembangan hutan kota berdasarkan sebaran suhu udara. Prioritas pengembangan hutan kota di Payakumbuh dinilai berdasarkan sebaran suhu udara, RTRW, dan tutupan lahannya. Kelas prioritas pengembangan hutan kota dibagi menjadi tiga yaitu rendah, sedang, dan tinggi. Pengembangan hutan kota yang memiliki prioritas pertama memiliki luasan wilayah sebesar 4.75 ha dengan persentase 0.06 % dari luas Kota Payakumbuh. Prioritas pengembangan hutan kota sebaiknya dilakukan pada pusat kota yang umumnya memiliki suhu udara yang lebih tinggi dibandingkan daerah pinggiran.

Judul: Potensi Pengembangan Hutan Kota Berdasarkan Distribusi Suhu Udara di Kota Palu
Abstrak: Pertumbuhan penduduk dan ekonomi mendorong peningkatan kebutuhan lahan di Kota Palu. Hal ini berdampak pada alih fungsi lahan bervegetasi menjadi lahan non vegetasi dan peningkatan suhu. Hutan kota adalah salah satu jenis ruang terbuka hijau yang dapat berperan dalam meredam suhu perkotaan.Tujuan penelitian ini adalah menentukan prioritas dan potensi lokasi pengembangan hutan kota berdasarkan distribusi suhu udara di Kota Palu. Citra Landat 8 OLI/TIRS dianalisis untuk mengetahui suhu udara, tutupan lahan dan nilai NDVI. Semua data diolah di perangkat lunak Arcmap versi 10.5. Prioritas dan potensi lokasi pengembangan hutan kota ditentukan melalui analisis tumpang susun data suhu udara, tutupan lahan, nilai NDVI dan RTRW Kota Palu. Prioritas pengembangan hutan kota terbagi ke dalam tiga kelas prioritas yaitu prioritas 1 seluas 6740,86 ha, prioritas 2 seluas 2743,78 ha dan priotas 3 seluas 20.695,04 ha. Prioritas 1 merupakan area-area yang paling direkomendasikan untuk dikembangkan menjadi hutan kota sebagaimana 98,31% dari luasnya bersuhu ?27,1 ?., Population and economic growth have driven an increase in land demand in Palu City. This causes the conversion of vegetated land to non-vegetated land and increasing temperatures. Urban forests are a type of green open space that can play a role in reducing urban temperatures. The aim of this research is to determine priorities and potential locations for urban forest development based on the distribution of air temperatures in Palu City. Landat 8 OLI/TIRS imagery was analyzed to determine air temperature, land cover and NDVI values. All data were processed in Arcmap software version 10.5. Priority and potential locations for urban forest development are determined through overlap analysis of the gathered data on air temperature, land cover, NDVI and Urban Land Use Plan of Palu City. Urban forest development priorities are divided into three priority classes, namely priority 1 covering an area of 6740.86 ha, priority 2 covering an area of 2743.78 ha and priority 3 covering an area of 20.695.04 ha. Priority 1 is the most recommended areas to be developed into urban forests as 98.31% of the area has a temperature of ?27.1 ?., ,

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.
