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: Evaluasi Tingkat Pencemaran Udara Berdasarkan Konsentrasi Udara Ambien Di DKI Jakarta
Abstrak: Pencemaran udara merupakan salah satu masalah besar yang dihadapi oleh negara berkembang. Pada penelitian ini dipelajari zat-zat polutan yang terdapat dikawasan pemukiman, industri dan komcrsil serta kesesuaian tata guna lahan berdasarkan konsentrasi udara ambien dan unsur-unsur meteorologis yang mempengaruhinya. Konscntrasi udara ambien tertinggi sebagian besar tejadi di kawasan komersi!. Polutan SO, tertinggi lerdapat di kawasan Komersil yaitu 12 ppb konsenlrasi lersebut masih berada di bawah baku mulu yailu 91 ppb. Parameter CO lertinggijuga le~jadi di kawasan komersil yailu 28.1 ppm, nilai [ersebut sudah melebihi baku mutu yaitu 7.2 ppm. Konsentrasi NO, dan Hidrokarbon tertinggi jue~ :eljadi di kawasan komersil, konsentrasi NO, tertinggi adalah 140 ppb yang nilainya melcbihi baku mu~u yailu 69 ppb dan konsentrasi Hidrokarbon tertinggi yaitu 3840 ppb juga melebihi baku mutu yaitu 240 ppb. Scdangkan untuk parameter PM-IO Konsentrasi tertinggi teljadi di kawasan industri Yaitu 113 ~g/m3, nilai tcrscbut masih berada di bawah baku mutu yaitu 150 ~g/m3 Kesesuaian lala guna lallan berdasarkan konsenlrasi udara ambien unluk wilayah Pluil adalah lidak sesuai sebagai peruntukkan Garis isoline menunjukkan ballWa \vilayah Pluit kon,entrasi pencemarnya sama dengan wilayah komersil untuk parameler SO, dan NO" sedangkan unlllk parameler CO dan HC konsentrasinya sama dcngan mlayah induslri. Lokasi Kclapa Gading yang juga mcrupakan wilayah pemukiman, konsentrasi PM-to wilayah industri. l'

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
