Judul: Distribution of CO Gas Analysis on Dramaga Highway Using the AERMOD Model
Abstrak: Sektor transportasi termasuk salah satu sumber utama pencemaran karbon monoksida di Kabupaten Bogor yang dapat menyebabkan gangguan kesehatan. Oleh karena itu, penelitian ini dilakukan untuk mengetahui pola penyebaran konsentrasi CO di Jalan Raya Dramaga dengan model AERMOD. Pengukuran konsentrasi CO menggunakan Air Quality Detector, lalu volume kendaraan dihitung secara manual untuk dimodelkan dengan AERMOD. Besaran emisi CO tertinggi terdapat pada segmen 1 saat pukul 16.30 - 17.30 sebesar 215.282 gram/km/jam, sedangkan besaran emisi terendah terdapat pada segmen 2 pukul 08.00 - 09.00 sebesar 148.806 gram/km/jam. Nilai konsentrasi CO tertinggi terletak pada titik reseptor 2 di Yogya Grand Dramaga pada sore hari pukul 16.30 - 17.30 sebesar 25.146 μg/m3, sedangkan nilai konsentrasi CO terendah terletak pada titik reseptor 4 di SPBU pada sore hari pukul 16.30 - 17.30 sebesar 13.805 μg/m3. Pola sebaran konsentrasi CO menunjukkan bahwa sebaran dominan menuju arah utara. Validasi konsentrasi CO hasil pengukuran langsung dengan model AERMOD menunjukkan nilai korelasi sebesar 77,76% yang tergolong korelasi cukup tinggi sehingga AERMOD dapat digunakan sebagai pemodelan konsentrasi CO dari sumber bergerak yaitu kendaraan bermotor.

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.
