Judul: Solusi Periodik Eliptik Jacobi Persamaan Modus Tergandeng Sistem Kisi Bragg
Abstrak: Persamaan modus tergandeng dalam tugas akhir ini adalah persamaan untuk sistem optik nonlinier yang bersifat periodik. Persamaan ini merupakan set persamaan diferensial parsial yang terkopel, dan untuk menganalisa kelakuan solusinya dilakukan melalui pendekatan analisis sistem dinamik. Berdasarkan pendekatan itu didapatkan sebuah set persamaan diferensial biasa orde satu yang akan dipecahkan secara analitik berupa fungsi Eliptik Jacobi (sn, cn, dan dn) dan dianalisa pula trayektori fungsi tersebut di bidang fasa.

Judul: Solusi Semi Analitik Propagasi Modus Transverse Magnetic Pada Pandu Gelombang Dielektrik Periodik
Abstrak: Salah satu terobosan baru mengatasi kelemahan piranti elektronik dalam mentransfer data adalah teknologi Kristal fotonik. Aplikasi dari Kristal fotonik contohnya pandu gelombang dielektrik periodik yang dikaji melalui persamaanpersamaan Maxwell. Tujuan penelitian ini adalah menentukan solusi persamaan Helmholtz modus Transverse Magnetic (TM) dan menganalisis solusi propagasi modus TM pada pandu gelombang dielektrik periodik dengan pendekatan analitik. Analisis yang dilakukan adalah distribusi intensitas terhadap jarak. Hasil distribusi intensitas ditentukan oleh 3 kondisi yang digunakan yaitu ketika koefisien propagasi bilangan gelombang , dan . Peningkatan nilai intensitas akan besar ketika nilai koefisien propagasi dan permitivitas bahan dielektrik yang diberikan bertambah. Sedangkan undulasi akan bertambah nilainya ditunjukan bentuk serutan gelombang bertambah rapat ketika nilai koefisien propagasi bertambah besar tetapi rentang jarak undulasi akan kecil ketika nilai permitivitas bahan dielektrik yang diberikan bertambah besar.

Judul: Amfibi sebagai satwa peliharaan: Ekspor, Impor dan Perdagangan Domestik
Abstrak: Indonesia has exported amphibian as frozen frog legs (listed since 1969 under fishery product) for consumption and live amphibian (listed since 1983 under reptilian class in forestry product) for pets. There are also live amphibian trading in local level i.e in markets and malls. This research aims to identify amphibian species exported and imported by investigating document from related administration and to identify amphibian species traded in domestic market by observation at Jakarta. Research is primarily conducted by processing quota data taken from Department of Forestry Republic of Indonesia database in Jakarta. Market observation was carried out in 18 locations (3 markets and 15 malls) in Jakarta. I carried out interview with trader and export business, which related to net trading live amphibians for pets. Respondent was choosen using snowball sampling manner. Name of species is written according to Iskandar & Coljin (2000). If there is no such record in the checklist (for example species are from outside Indonesia), then the species name is written according to Frost (2004). There are 56 species from eight families of wild amphibians that have pets quota between 1998-2008. Nineteen species was traded since 1983. The highest export quota is Litoria caerulea (21,37%). Allocation of highest catching quota is for BKSDA Jayapura (20,40%) and BKSDA Papua Barat (18,96%). Four species are included in IUCN Red List categories as vulnerable, among others are Limnonectes macrodon, Meristogenys jerboa, Nyctixalus margaritifer and Rhacophorus margaritifer. The number of amphibians that have export realization are 39 species. Two species of amphibian, Leptobrachium hasseltii and Rhacophorus margaritifer are amphibian species whose been known infected by chytrid fungus in the wild. The biggest species exported is Litoria caerulea (54,34%). Between 1983-1991, the biggest import amphibian for pets from Indonesia (66,13%) is Netherlands. Number of quota was relative stable in the last eight years, where as the number of export realization is more fluctuates. Amphibian species imported and re-exported between 1983-2008 come from Africa, South Asia, Malaysian, Archipelago Oceania, North America, Central America and South America. The number of pet amphibian species traded at domestic market is less than exported. Data showed that Indonesia imports 15 amphibian species between 1983-2008, However I found different species in the market that was unrecorded in the Ministry of Forestry data, which is the Fire Belly Salamander.
