Judul: Analisis Atribut Produk Yang Mempengaruhi Keputusan Pembelian Varanus Oleh Penggemar Reptil di Bogor dan Sekitarnya
Abstrak: Varanus are pledge export commodity in Indonesia, but not really explore by indonesian goverment. Varanus can be exported as a pet a side from exported the meat and skin. Indonesia had most species Varanus compared with any other countries. From 35 species in the world theres 20 species can be found in Indonesia and the quantity are increased. As time goes by a lot species and subspecies founded more in Indonesia. And the objective of this research are: 1) To analyses the purchasing decision of Varanus by reptile lovers. 2) To analyses the attribute of what dominan to push purchase of Varanus in for reptile lovers. Based on research in a procceses purchasing decision in a step to buy Varanus can be known in a introducing purchasing decision, motivation of buy the most dominant are needs of hobby, and the first benefit hope can be used as an entertained media and the level of consumer interactive are feels empty when they have no Varanus. In information research step, main source information and the most affect are internet and friends. The most feck unsure from Varanus advertise are motives of Varanus. Product information can be attention are perfectly phisically, and advertising can focused inVaranus purchasing. In evaluation step alternative, the main factor in Varanus purchase and expectation showed quality indicator of Varanus are motives spesification. On a purchasing decision, consumer refer to choose Varanus are phisically perfect, a place to buy Varanus are from internet, decision situation are planned, and the most buyed Varanus are V.Indicus. In a step of after purchasing behaviour, the attitude after purchasing feels by consumen are satisfied. In factor analyses, result of factor analyses formed 3 (three) factors who affect purchasing desicion Varanus product. First of all consist of variables of price, type, physic, colours, motives, treatment level, and body shape. Second factor consist of locality variables and size. Third factor consist of popularity variables. Variable of price, type, physic, colour, motives, treatment level, and body shape of Varanus are the most dominant variables and push purchasing desicion of Varanus.

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: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
