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: Perilaku Komodo (Varanus komodoensis) di Taman Margasatwa Ragunan
Abstrak: The komodo (Varanus komodoensis) is the world's largest lizard that prone to extinction since they only scattered in some small islands in eastern Indonesia. One preservation effort of the dragons is by breeding them in captivity places, such as Jakarta Ragunan Zoo. Eventhought in the captivity, it does not mean there are no problems faced by the komodo. The main problems are because of differences in the weather and environmental conditions. Therefore, the aim of the research is to conduct behavioral assessments of the komodo preserved in the Ragunan Zoo as the first step to resolve the problems. We used observational method called scan sampling. Observations were conducted in two periods of time, i.e. during the daylight (06.00 am-06.00 pm) and evening (6.00 pm-06.00 am). Observations of the behavior of the komodo included walking, stay still, sun bathing, rubbing body, yawn, drinking, eating, climbing, secreting saliva, craning of the tongue, and running. During the daylight, some of the behaviors were more dominant, i.e. walking, stay still, sun bathing, climbing, secreting saliva, and craning of the tongue. While during the night stay still was dominant.

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
