Judul: Contribution of Long-Range Transport Towards PM 2.5 Concentration (Study Case: Baranangsiang, Bogor)
Abstrak: Fenomena long-range transport (LRT), merupakan pengangkutan polutan dari daerah lain dengan jarak lebih dari 100 km. Perlu dilakukan identifikasi potensi sumber PM2.5 dan melihat fluktuasi konsentrasi PM2.5 di Kota Bogor. LRT dapat divisualisasikan menggunakan lintasan mundur HYSPLIT dan klustering. Selain itu, metode Potential source contribution function (PSCF) digunakan untuk menilai probabilitas dan metode Concentration weighted trajectory CWT untuk melihat nilai konsentrasi dominan. Sumber potensial dan tingkat konsentrasi dapat bervariasi berdasarkan musim di wilayah tersebut. Pada bulan kering sumber polutan dominan berasal dari arah timur-tenggara sebesar 57.7% dan pada bulan basah berasal dari arah barat-barat daya sebesar 67.1%. dan 32.9 %. Konsentrasi maksimum rataan bulanan PM2.5 di Kota Bogor terjadi pada bulan Juli dengan nilai sebesar 25 µg/??3 dan minimum pada bulan November sebesar 10 µg/ ??3 . Secara umum faktor kecepatan angin curah hujan, dan kelembaban memiliki hubungan yang negatif dengan PM2.5. Jika kecepatan angin tinggi maka polutan akan rendah, curah hujan tinggi maka konsentrasi menurun, dan kelembaban tinggi konsentrasi akan turun., The phenomenon of long-range transport (LRT) is that pollutants can be transported from other areas. Identify the potential source of PM2.5 in Bogor City and see the fluctuation of concentration of PM2.5in Bogor City. Transport distance with a backward trajectory using the HYSPLIT model, clustering. Use PSCF for knowing probability and knowing concentration using CWT method. It is important to understand potential sources and concentration levels may vary seasonally in the region, potential sources will follow the season of the area. The dry month was the dominant pollutant from east-southeast was 57.7% and in the wet month from the west-southwest 67.7%. Concentration of PM2.5in Bogor City maximum is 25 µg/??3 and the minimum is 10 µg/??3 in July. Because meteorology factors can impact, such as wind, humidity, and rainfall, they have a negative correlation. If humidity and wind increased the concentration will be decreased, rainfall increases the concentration will be decreased.

Judul: Analisis Sebaran Konsentrasi PM2,5 Menggunakan Model AERMOD Di Jalur Protokol Kota Bogor
Abstrak: Sektor transportasi dapat berkontribusi besar terhadap peningkatan pencemaran di Indonesia salah satunya yaitu terjadi di Kota Bogor. Berdasarkan hal tersebut, maka diperlukan pemantauan konsentrasi PM2,5 dengan cara melakukan analisis sebaran PM2,5 di beberapa titik jalan di Kota Bogor dengan pemodelan AERMOD. Sebaran konsentrasi PM2,5 dilakukan dengan menggunakan pemodelan AERMOD. Pengukuran konsentrasi PM2,5 dilakukan secara langsung di lapangan dan bertujuan untuk memvalidasi hasil konsentrasi dari pemodelan dengan AERMOD. Nilai konsentrasi PM2,5 hasil pemodelan memiliki nilai tertinggi yaitu sebesar 85,5 µg/m3 dan nilai terendah yaitu sebesar 5,6 µg/m3. Sedangkan nilai tertinggi pada pengukuran yaitu sebesar 53,68 µg/m3 dan nilai konsentrasi terendah yaitu sebesar 23,75 µg/m3. Perbandingan antara konsentrasi PM2,5 di lapangan dengan hasil pemodelan memperoleh nilai R2 pada hari Senin yaitu sebesar 0,7022, hari Kamis sebesar 0,5956, hari Sabtu 0,712, dan hari Minggu sebesar 0,7963. Nilai konsentrasi PM2,5 di udara ambien tidak hanya dipengaruhi oleh volume lalu lintas, beberapa faktor lain yang dapat memengaruhi nilai konsentrasi PM2,5 di lapangan yaitu kondisi meteorologis di titik lokasi, seperti suhu, kelembaban dan kecepatan angin., The transportation sector can contribute greatly to the increase in pollution in Indonesia, one of which occurs in Bogor City. Based on this, it is necessary to monitor PM2,5 concentrations by analyzing the distribution of PM2,5 at several road points in Bogor City using AERMOD modeling. The distribution of PM2,5 concentrations was carried out using AERMOD modeling. Measurement of PM2,5 concentrations was carried out directly in the field and aimed to validate the concentration results from modeling with AERMOD. The PM2,5 concentration value from the modeling results has the highest value of 85.5 µg/m3 and the lowest value of 5.6 µg/m3. While the highest value in the measurement is 53.68 µg/m3 and the lowest concentration value is 23.75 µg/m3. Comparison between PM2,5 concentrations in the field with modeling results obtained an R2 value on Monday of 0.7022, Thursday of 0.5956, Saturday of 0.712, and Sunday of 0.7963. The value of PM2.5 concentration in ambient air is not only influenced by traffic volume, several other factors that can affect the value of PM2,5 concentration in the field are meteorological conditions at the location point, such as temperature, humidity and wind speed.

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.
