Judul: Pendugaan konsentrasi permukaan polutan sulfur dioksida (SO2) menggunakan model gaussian (studi kasus : PT. Yamaha Motor Manufacturing, Jakarta)
Abstrak: Masalah perkotaan pada saat ini telah menjadi masalah yang cukup pelik untuk diatasi. Salah satunya, yaitu peningkatan polusi udara. Peningkatan polusi udara disebabkan berbagai aktivitas mauusia salah satunya adalah industri. Hasil dari pembuangan limbah industri ke udara salah satu gas nya adalah SO2 (Sulfur Dioksida).

Judul: Model Prediksi Distribusi Laju Penyebaran Sulfur Dioksida (SO2)dan Debu dari Kawasan Industri (Studi Kasus di Kota Cilegon)
Abstrak: This study aims to examine the characteristics of local air; analyze the concentration of air pollution emitted from factories located in an industrial area; and predict air pollution distribution the city of Cilegon. Several sequential steps of analysis are carried out which include: (1) calculation of high-layer pollutant mixing in the atmosphere (mixing height), (2) analysis of emission of air pollutant from the source point using screen3 model; (3) analysis of distribution of air pollutant from the industrial area using general transport equation of unsteady flow. Based on climatology, Pasquill stability criterian indicate that stability profile in the region ranges from A (very unstable) to E (slightly stable). Pollutant distribution from the industry depends on the height of the chimney. The higher the chimney is, the further the distribution of the pollutant as a result of emission is expected to be. The highest concentration of SO2 is found in the emission of industry area, with atmosfheric stability class A (very unstable), whereas furthest distance occurred stability E class (slightly stable). The distribution of SO2 extends towards Tamansari village of Pulomerak District. From 24 sampling points, the highest concentration of 55,75 ìg/m3 occurred in the ASDP Merak. The levels and patterns of air pollutant distribution in the area need to be taken into account, particularly in the interest of protecting public healthlife from the impacts caused by the pollutant.

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.
