Judul: Evaluasi Hari Bebas Kendaraan Bermotor (HBKB) dan Pengaruhnya terhadap Emisi Polutan (Studi Kasus: Jalan RE Martadinata, Kota Bogor, Jawa Barat)
Abstrak: Hari Bebas Kendaraan Bermotor (HBKB) merupakan sebuah kampanye kegiatan untuk mengurangi emisi polutan serta mensosialisasikan kepada masyarakat agar menurunkan ketergantungan terhadap kendaraan bermotor. Namun, pelaksanaan HBKB menimbulkan permasalahan baru yaitu terjadinya kemacetan di ruas jalan yang difungsikan sebagai jalur pengalihan arus, seperti yang terjadi di Jalan RE Martadinata, Kota Bogor. Penelitian ini bertujuan menduga emisi dan konsentrasi polutan CO, HC, PM10, SO2, NOx yang dihasilkan oleh kendaraan bermotor selama HBKB berlangsung (pukul 06.00-09.00 WIB) di Jalan RE Martadinata dan dibandingkan dengan hari kerja serta hari libur non-HBKB. Penelitian ini menggunakan Fixed-Box Model dan model FLLS (Finite Length Line Source). Hasil menunjukkan adanya peningkatan jumlah kendaraan bermotor di Jalan RE Martadinata sebesar 1.3% dan 17.2% jika dibandingkan dengan hari kerja dan hari libur non-HBKB. Selain itu, terdapat peningkatan jumlah beban emisi polutan CO, HC, PM10, SO2, NOx masing-masing sebesar 27.7%, 18.0%, 16.0%, 3.6% dan 0.1% jika dibandingkan dengan hari libur non-HBKB. Jumlah beban emisi polutan ketika HBKB tidak berbeda jauh dengan hari kerja. Emisi polutan CO, HC, dan PM10 di Jalan RE Martadinata paling banyak dihasilkan oleh sepeda motor karena jumlah sepeda motor yang melintas paling tinggi dibandingkan dengan kendaraan lain, sedangkan polutan SO2 dan NOx lebih banyak dihasilkan oleh mobil penumpang. Hasil pendugaan konsentrasi dan dispersi polutan menunjukkan jumlah konsentrasi polutan di Jalan RE Martadinata serta di lokasi reseptor masih di bawah baku mutu udara ambien.

Judul: Evaluasi Dampak Hari Bebas Kendaraan Bermotor Terhadap Polutan Berdasarkan Konsentrasi dan Faktor Meteorologi di DKI Jakarta (Studi Kasus Jalan M.H. Thamrin-Jalan Jend. Sudirman)
Abstrak: One of the main problems at several cities in developing countries is air pollution, for example is Jakarta. The biggest source of air pollution comes from the transportation sector. The increasing number of motor vehicle every year in Jakarta will increase the air pollution. The parameters of gas pollutant from motor vehicle are dust particulate < 10μm (PM10), carbon monoxide (CO) and nitric oxide (NO). The Car Free Day Program (CFD) is held to recovery the air quality. The goal of this research are analyzing the trend of pollutant concentration, analyzing air quality at Jakarta from the Air Quality Index (AQI) and studying the impact of CFD program based on pollutant concentration & meteorology factor in Jakarta from 2006 to 2009. This research is conducted by using continued data perception result of air ambient, sampling the air at some location where CFD was held, and then compare the result with data perception from mobile station on workday, holiday and by the time CFD was held. According to the perception from 2006 to 2008, the air quality of the roadway in Jakarta can be categorized as “Good” for 45 days in 2006, 73 days in 2007 and 148 days int 2008. This result show the increase of air quality in Jakarta. The concentration of PM10, CO, and NO parameter had been lower during CFD, compared to workdays. The decreasing level of pollutant concentration during CFD in 2009 are 38%, 63%, and 71% for PM10, CO and NO respectively. The correlation between PM10 parameter with the wind speed is -0,737 – 0,919. The correlation between CO parameter with the wind speed is -0,054 – 0,512. Meanwhile, the correlation between NO parameter with the wind speed is -0,11 – 0,856. The result of this research indicates that the CFD program helps recovering the air condition of roadway in Jakarta especially at M.H. Thamrin street and Jend. Sudirman street.

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.
