Judul: Perencanaan Jalur Hijau untuk Mengurangi Polusi Partikel Akibat Aktivitas Transportasi pada Simpang Susun Cawang, Jakarta Timur
Abstrak: Transportation activities on the street is on the increase and causing negative impact namely pollution. To overcome this under ideal condition, an approach that can be used as one of the solutions is green spaces such as greenery. Greenery of streetside can decrease pollution on its surrounding areas. The location of this research was Cawang interchange, East Jakarta. There were two objectives which were provided by the research: 1) to measure dust that was adsorbed by the greenery of Cawang interchange and 2) to arrange a planting plan of Cawang interchange greenery. The process of this research consist of several phases e.g. commission, research, analysis, and synthesis. Otherwise, gravimetry method was used to found the full measure of greenery capacity in adsorbing particles (dust). This research showed that Ficus benjamina was the species which has the highest capacity in adsorbing dust beside other three sample species (Mimusoph elengi, Cerbera manghas, and Polyalthia fragrans). Therefore, it was important to consider sort of species, number, and location pattern of the greenery in arranging the planting plan to reduce particles. The output of this research was planting plan of Cawang interchange greenery.

Judul: Perencanaan Tata Hijau Simpang Susun Dawuan Jalan Tol Cikampek
Abstrak: Traffic jam have been the most pressing issues in big city. These problems were caused by human population growth, economic growth, and transportation. Vehicle activities increase air pollution on high level. To overcome this problem, green open space in the site is needed as a solution. This research is located in Dawuan interchange at Cikampek toll road. The purpose of this research are to measure total of particle limited by traffic and tree population needed, and to arrange planting plan in Dawuan interchange. The process of this research consists of several phases e.g. commission, research, analysis, and synthesis.The result of the research is arrangement of vegetation by the functions as buffer, direction, conservation, identitiy, and aesthetic. Total emission of particle produced by vehicle approximately is 233.723 g/day, and to adsorb the particle emission 8.958 trees are needed. In case, the site only can be planted by 5.229 trees, so that 3.729 trees still needed to adsorb those emission of dust. Recommended vegetation are Samanea saman, Acassia auriculiformis, and Melaleuca leucadendra.

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.
