Judul: Bangkitan Debu Jatuh dan Total Partikel Tersuspensi Akibat Pengaruh Lalu Lintas
Abstrak: The increasing vehicle usage contributes to the rise of dustfall (DF) and suspended particles (TSP) concentration. The purpose of this study was to measure the generation of DF and TSP due to the number of vehicles (JK) and to analyze their correlation. This study was conducted on four roads,namely Ciomas, Dramaga,Sindang Barang and RE Abdullah roads. The study was conducted by installing dustfall canister for 24 hours.High volume air sampler was operated for 60 minutes simultaneously with traffic counting. The DF generation at four sampling points were less than 1 ton/km2.month. The range of TSP generation on Ciomas, Dramaga, Sindang Barang, and RE Abdullah were 57-243, 37-86, 37-177, 60-117 μg/Nm3 respectively. The significant value (α) between DF generation and JK type I in the morning was 0.037, type II in the morning was 0.002, type III in the morning was 0.031, type III was 0.001 in the night and type VI b was 0.009 The significant value between TSP generation and type III in the night was 0.002, type III total was 0.001, type VI a was 0.04 and type VI b was 0.019.

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: Karakteristik Anatomi Skelet Kepala Buaya senyulong (Tomistoma schlegelii).
Abstrak: Buaya sepit atau senyulong (Tomistoma schlegelii) merupakan jenis buaya asli Indonesia yang berhabitat di sungai-sungai Sumatera, Kalimantan, dan juga pedalaman Sulawesi. Salah satu ciri khas buaya senyulong adalah bentuk moncong yang runcing dan sempit, namun hingga saat ini informasi mengenai struktur skelet kepala buaya senyulong sangat terbatas. Penelitian ini bertujuan untuk mempelajari karakteristik anatomi skelet kepala buaya senyulong yang dikatikan dengan fungsi dan perilakunya. Penelitian dilakukan secara eksploratif dengan melakukan pengamatan, pencatatan, dan pengambilan gambar dari skelet kepala buaya senyulong. Skelet kepala berukuran panjang 70 cm, lebar 29 cm, dan tingggi 17 cm dengan permukaan kasar pada os nasale, os frontale, os maxilla, os mandibula, os lacrimale, os jugale. Jumlah gigi pada buaya ini sebanyak 78 buah, terdiri dari 4 buah gigi premaxila, 16 buah gigi maxila, dan 19 buah gigi mandibula. Pada regio orbitalis ditemukan dua pasang fenestrae temporales yang berkembang baik. Fenestra supratemporale merupakan lubang oval yang membentang di sepanjang os parietale. Fenestra infratemporale berbentuk segitiga dan dibatasi oleh os squamosum, os postorbitale, os jugulare, dan os quadratum. Os mandibula hewan ini mempunyai symphysis mandibularis yang panjang yaitu garis yang melintang di corpus mandibulae. Secara fungsional ukuran symphysis mandibularis berkaitan dengan adaptasi hewan terhadap diet makan.
