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: Analysis of PM10 Distribution Using AERMOD View Model in Jalan Raya Gunung Putri, Kabupaten Bogor
Abstrak: Sektor transportasi menjadi salah satu penyumbang terbesar polusi akibat dari emisi atau zat buang yang dihasilkan pada proses pembakarannya. Parameter pencemar udara ambien yang dihasilkan oleh aktivitas sektor transportasi salah satunya yaitu Particulate Matter 10 (PM10). PM10 pada jangka panjang dapat menyebabkan berbagai macam gangguan kesehatan. Oleh karena itu, analisis pola sebaran konsentrasi PM10 di Jalan Raya Gunung Putri dengan pemodelan AERMOD perlu dilakukan. Hasil pengukuran langsung di lapangan diperoleh besarnya konsentrasi PM10 pada hari kerja berkisar antara 72,80 - 135,39 µg/m3 sedangkan pada hari libur berkisar antara 50,68 - 82,52 µg/m3. Jumlah kendaraan yang melintas menjadi salah satu faktor yang mempengaruhi besarnya nilai konsentrasi PM10, semakin banyak kendaraan yang melintas konsentrasi PM10 juga akan meningkat. Pola sebaran konsentrasi PM10 dengan AERMOD View pada hari kerja berkisar antara 33,78 – 238,49 µg/m3 sedangkan pada hari libur berkisar antara 17,20 – 110,90 µg/m3 dengan arah angin bergerak dominan ke arah Tenggara. Konsentrasi PM10 di beberapa segmen jalan seperti segmen 1, segmen 2, dan segmen 6 tidak memenuhi baku mutu, yaitu lebih besar dari 75 µg/m3., The transportation sector is one of the biggest contributors to pollution due to the waste substances produced during the combustion process. One of the ambient air pollutant parameters produced by transportation sector activities is PM10. Long-term exposure to PM10 can lead to various health issues. Therefore, an analysis of the dispersion pattern of PM10 concentrations on Gunung Putri Highway using AERMOD modeling is necessary. Direct field measurements indicate that PM10 concentrations during weekdays range from 72,80 to 135,39 µg/m3, while during weekends they range from 50,68 to 82,52 µg/m3. The number of passing vehicles is one of the factors influencing the magnitude of PM10 concentrations; the more vehicles passing by, the higher the PM10 concentration. The dispersion pattern of PM10 concentrations with AERMOD View on weekdays ranges from 33,78 to 238,49 µg/m3, while on weekends it ranges from 17,20 to 110,90 µg/m3, with the wind predominantly moving towards the Southeast direction. PM10 concentrations on certain road segments, such as segments 1, 2, and 6, exceed the standard threshold, which is greater than 75 µg/m3.

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.
