Judul: Lizard (Mabuya multifasciata) Behavior in Captivity
Abstrak: The Mabuya multifasciata lizard are known as common lizard and spread out widely in Indonesian archipelago. Traditionally, this lizard is used as skin medicine for human, protein source, raw material for leather industry and reared as a pet. To increase lizard population and to prevent lizard from extinction, it is important to breed the lizard in captivity. Therefore, their behavior in captivity was conducted.

Judul: Manajemen Penangkaran, Morfologi dan Aktivitas Harian Biawak Ekor Biru (Varanus doreanus AB Meyer 1874) di PT Mega Citrindo
Abstrak: PT Mega Citrindo is one corporate engaged in the trade (export) species of reptiles. The high demand of society to increasingly threaten the existence of reptiles wildlife animals in the wild. This corporate has been doing business a captive reptile is one of the blue tail monitor. This research aims to study the technical aspects of breeding management blue tailed monitor (Varanus doreanus), know the quantitative and qualitative characteristics of a blue tail monitor morphology as a determinant of sex and age classes and observe the daily activity of the blue tailed monitor in the cage. This study was conducted in April to May 2010 at PT Mega Citrindo. The method used is direct observation, interview and literature study. Data collected include the technical aspects of breeding, morphological characteristics of lizards both quantitatively and qualitatively the basis of sex and age classes and the daily activity of lizards in the cage. Data were analyzed by descriptive equipped with pictures, tables and graphs that are relevant. Captive breeding of a blue tail monitor in this corporate include the type of captivity been intensified with the economic objectives. This corporate has two types of cages for the blue tail monitor, which is a permanent enclosure as a place for adolescents and adults living lizard cage boxes and then container as a place to accommodate the young lizard before exported. Total length (from head-tail) of adult male lizards body average is 127.33 cm, while the adult female measuring 127 cm on average. This suggests that lizard body size of adult male and adult female relative is almost the same but age is not known for certain lizards. But if at the same age male lizards have a larger body size than females. Based on test results of chi-kuadarat on observations obtained X2 lizard activity count (205.66) > X2 table (15.507), so it can be proven that the daily activity time allocation for each lizard at times is a different age class. Captive breeding of this still needs more attention because the lizard has not been successfully bred. Blue-tailed monitor, including species that are morphologically monomorphic difficult to distinguish gender. Male lizards have a brighter color hue as compared to females. When grown in blue fade on the tail and body color will change from black to grayish black. More adult lizards sunbathing activity and rest, do more teens lizard feeding activity and resting while the lizard more tillers moving activity.

Judul: Solusi Problem Gaussian Pairing Dalam Basis Osilator Harmonik Menggunakan Teori Perturbasi Dan Metode Numerik
Abstrak: This study aims to determine the profile of the energy and the wave function of a harmonic oscillator system under the effect of a Gaussian potential. This function can be used to model such fermions. The solution of this problem can be described by more efficiently using a perturbation theory based on the harmonic oscillator. The first four levels of energy and the wave function has been described using the analytical method and Numerical Methods . These results are displayed in graphical form . Wave function is shown in graphic form relation between the wave function and atomic distance, whereas energy shown in the form of relation between energy and the pairing constant g. From the graph shows that the ground state and the first excitation energy of the system will decrease with increasing pairing constant g, whereas for the higher excitation energy of the system increases with increasing pairing constant g. This is because when the system is in the ground state and the first excitation, the system tends to be localized in one place, whereas at higher excitation , the system will often be not only in one place, but some places are indicated by the peaks of density of system . Energy system obtained from the analytical and numerical methods haven’t significant. This is mean that to analize a higher excitation state can use numerical methods such as Numerov Method and Shooting Method to be more efficient
