Judul: Kualitas Udara Ambien Berdasarkan Kondisi Atmosfer di Luar dan di Dalam Hutan Kota Monumen Nasional Jakarta
Abstrak: Hutan kota memiliki berbagai manfaat, salah satunya sebagai lokasi olahraga karena dianggap memiliki kualitas udara yang baik. Namun, kualitas udara dipengaruhi oleh berbagai faktor sehingga kualitas udara yang baik di dalam hutan kota tidak mutlak terjadi. Monumen Nasional dipilih sebagai lokasi penelitian karena terletak di pusat kepadatan lalu lintas Jakarta. Penelitian ini bertujuan untuk menganalisis kualitas udara ambien untuk parameter NO2, SO2, CO, dan Pb di luar dan di dalam hutan kota Monumen Nasional Jakarta. Sampel udara diambil pada pukul 05.00-06.00 WIB dan 09.00-10.00 WIB di jalan dan pukul 06.51-07.51 WIB dan 10.31-11.31 di hutan kota. Data pendukung berupa volume kendaraan, faktor meteorologi (suhu udara, kelembapan udara, arah dan kecepatan angin), vegetasi (komposisi jenis, stratifikasi tajuk, dan leaf area index), dan persepsi masyarakat. Konsentrasi polutan sebelum pukul 09.00 WIB lebih tinggi dibandingkan konsentrasi polutan setelah pukul 09.00 WIB. Konsentrasi polutan sebelum pukul 09.00 WIB lebih tinggi di luar hutan kota, sedangkan konsentrasi polutan setelah pukul 09.00 WIB lebih tinggi di dalam hutan kota. Namun, konsentrasi polutan udara di kedua titik lokasi masih di bawah baku mutu udara ambien sehingga masih aman untuk beraktivitas.

Judul: Pengujian Kualitas Udara Ambien Jalan Raya Kota Bekasi.
Abstrak: Air polution in Bekasi City is caused by 70% of transportation sector, 20% of industry sector, and 10 % domestic sector. Thus, in order to reduce air polution and improve the ambient air quality in Bekasi city , it needs to reduce air pollution produced either from tranportation or industrial sector. Based on the results of ambient air quality test along the roadside of Bekasi City during three periods in the year 2011, it showed that there are 2 parameters obtained which relatively increase, they are the TSP / dust and CO. For almost all parameters of CO along the observation points increased to the limit of specified quality standards. Parameters of TSP has highly increased throughout the year 2011. Almost TSP point exceed threshold quality standard (TQS). Based on the secondary data of CO concentration in 2010, the CO concentration is high in the morning and afternoon, and lower during the day and night. Ambient air quality in Bekasi city from 2009 to 2011 has decreased with increasing amount of tested pollutant concentrations, especially on the concentration of CO and TSP which have inclining done

Judul: Perilaku Kawin dan Siklus Reproduksi Deroceras laeve, Filicaulis bleekeri, dan Meghimatium bilineatum (Mollusca: Gastropoda)
Abstrak: Deroceras laeve, Filicaulis bleekeri and Meghimatium bilineatum are members of Gastropoda (Mollusca) that live as pest. However they are potential for protein source of animal livestock. Mating behavior and reproductive cycle of those were inspected for 42 days. The mating phase of F. bleekeri and M. bilineatum started from touching each other with tentacle or touching another slug’s body or tail with tentacle, slug come closer to other which will be the partner, stuck each other position, and withdrawal. The mating phase of D. laeve investigated slug touched body or tail another slug with tentacle. Mating behavior of M. bilineatum and F.bleekeri which stick each other position was the longest mating duration (average 281,4 second and 561,9 second respectly) during 42 days observation. D. laeve produced 264 eggs, took average incubation period for 14 days and had hatching percentage 60.98%. The fecundity per individual is 0.31/day.
