Judul: Pemanfaatan Reptil Sebagai Obat dan Makanan di Daerah Khusus Ibu Kota (DKI) Jakarta
Abstrak: Economic crisis in Indonesia urge people to utilize natural resources including reptile. Reptile used to be regarded as adverse thing, now becoming profitable comodity for medicine and food. Nowadays, demand for reptile is increasing so that creates more risk for sustainability of reptile because most of reptile hunted from wild. The aim of this research was to know the characteristic of reptile traders and consumers, to know the utilization of reptile as medicine and food products and to investigate reptile trafficking in DKI Jakarta. This research was carried out from November until Desember 2008 in DKI Jakarta. The direct observation and interview to the traders and consumers were be used to collect data. There were ten traders selected by purposive sampling method. Whereas 30 consumers were selected based on the average of daily visitors. Most of traders were Indonesian male with average age of 43 years old and having selling experience for 2-43 years. Most of consumer were Indonesian male with the average of age 34 years old. Their education background were senior high school. There were 13 species (southern Indonesian spitting cobra, king cobra, reticulated python, copperhead racer, mangrove snake, banded krait, Malayan krait, ground pit viper, Indian rat snake, asian water monitor, tockay, skink and southest asian softshell turtle) of reptiles that be used as medicine product (fresh blood, salve, capsule, cream, oil, dried gall bladder, dried male genital and powder). There were 7 species (southern indonesian spitting cobra, reticulated python, crocodile, asian water monitor, tockay, skink and southest asian softshell turtle) were used for food products (roasted meat, soup, frieds meat and fried meat powder). Reptile trafficking in DKI Jakarta was divided into 2 networking system, which are: 1) small scale trader (wild reptiles- hunters - primary collectors - secondary collectors - small scale traders - consumer) and 2) large scale trader (wild reptiles - hunters - primary collectors – small scale productions - large scale traders - consumers). People usually utilize reptile for treating skin diseases. It is necessary to control reptile hunting in order to prevent those species from extinction. Breeding in captivity is on off alternatives to reduce hunting of reptile from the wild. Formal monitoring and regulation in reptile utilization by BKSDA DKI Jakarta, monitoring and contolling by BPOM DKI Jakarta as well as research on bioactive content in reptile meat

Judul: Pembuatan Film Tipis Lithium Niobat (LiNbO3) Menggunakan Metode Chemical Solution Deposition (CSD) dengan Variasi Kecepatan Putar (Rpm).
Abstrak: Film tipis merupakan salah satu aspek yang mendapat perhatian sangat besar dalam bidang material, karena film tipis merupakan material menarik yang memiliki sifat optik yang sangat tergantung pada konstanta dielektrik, indeks bias, dan energi gap. Lithium Niobat (LiNbO3 ) dapat digunakan sebagai pelapis pada film tipis karena memiliki sifat piezoelektrik, electrooptical, pyroelectrical dan photorefractive yang sangat baik. Film tipis Lithium Niobat (LiNbO3 ) ditumbuhkan menggunakan metode Chemical Solution Deposition (CSD) dengan variasi kecepatan 3500 rpm, 5000 rpm, 6500 rpm, dan 8000 rpm. Metode ini memiliki keunggulan dapat mengontrol stokiometri film tipis dengan kualitas yang baik, prosedur yang mudah dan membutukan biaya yang relatif murah. Energi band gap yang dihasilkan dari film tipis Lithium Niobat (LiNbO3) berkisar antara rentang 2.1 eV – 2.8 eV dengan indeks bias berada pada rentang 2.18-3.2. Film tipis LiNbO3 memiliki parameter kisi a=b=5.54Ǻ dan c = 16.35 Ǻ. Struktur morfologi film tipis adalah permukaan yang homogen dan ukuran kristal berada pada rentang 0.417 μm – 0.680 μm.
