Judul: Adaptation of translocated sumatran tiger (Panthera tigris sumatrae, Pocock 1929) in Blangraweu Forest, Nanggroe Aceh Darussalam
Abstrak: Sumatran tiger known as the critically endangered species hence its existence need to be conserved. This animal needs a wide area to survive. Fragmented forest that become more threatening in later years turn out into a high level of threat for the tiger. People invade tiger’s habitat and causing human-tiger conflict.Translocation is one of solution to overcome the human-tiger conflict, and one of the practice is translocated tiger in Ulu Masen Ecosystem. This research is to support this program. The research conducted from December 2009 until May 2010 in around Blangraweu Forest inside Pidie and Pidie Jaya Regency, Aceh. According to the land cover, Blangraweu Forest consist of primary forest, secondary forest, and highland meadow. Based on the altitude, this forest consist of lowland tropical forest, highland tropical forest, and mountain tropical forest. The data collected in three stage including spatial data collection, field inventarization by camera trap and rapid survey method, and secondary data collection by interviewing people and stakeholders of Blangraweu Forest management. Resident tiger and prey encounter was analyzed by O’Brien equation. Home range of translocated tiger was analyzed by Minimum Convex Polygon (MCP) 100% method. Then the data was analyzed descriptively to find the influence of habitat factors toward the adaptation of translocated tiger. Translocated tiger daily movement is 1,84 ± 1,41 km/day with the furthest travelled distance reaching 6,89 km in a day. In the early release, translocated tiger was actively explored its new area. In just 10 days after its release, the tiger was moved as far as 31,63 km. On April, this translocated tiger had moved as far as 23 km and migrated into the North. This tiger was then found dead in a wild boar trap in July. Total area that used by translocated tiger is 540,60 km2. It was taken about 4 months to explore all of this area. Home range of translocated tiger divided into two area, the South –home range after released– and the North –home range after migrated– with each area is 225,54 km2 dan 153,50 km2. According to the habitat factors analysis result, the most factor affecting translocated tiger movement is the population density of resident tiger. Another factors like prey abundance, land cover, and water source is appropriate with the tiger requirement.

Judul: Potensi populasi dan karakteristik habitat harimau Sumatera (Panthera tigris sumatrae, Pocock 1929) di hutan Blangraweu - Ekosistem Ulu Masen, Provinsi Aceh
Abstrak: Sumatran tiger’s condition was threatened by forest over function, with the result of decreasing its population. Blangraweu forest area is one of suitable habitat and potential for Sumatran tiger existence. There is no recently data, which can be estimating about population of Sumatran tiger is a problem in tiger sustainability, especially in Aceh. This research was held for six months, started on November 30th 2009 until May 28th 2010 in Blangraweu forest area – Ulu Masen ecosystem, Pidie and Pidie Jaya, Aceh. The purpose is to estimate population density, and to identify habitat component and characteristic of Sumatran tiger in Blangraweu forest. The data was collected by camera trap method and vegetation analysis to find vegetation structure and composition where consist of its habitat. Population Estimation of Sumatran tiger in Blangraweu forest area is 5 – 9 individuals per 211,25 km2 effective sampling area. Density level of Sumatran tiger with 95% deviation standart is about (X  SE) 2 – 4 individuals (2,36 – 4,07  2,43 individuals/100 km2). Sex comparison between male and female positively is 1 : 4, which age structure are 5 adult individuals. Blangraweu forest has two type of habitat, are mountain and sub-mountain forest. Main preys are sambar deer, deer, and bearded pig. Water resources which used by Sumatran tiger source is river during the year with pure water. Crown cover as forest has main function to covering Sumatran tiger. Habitat disturbances of Blangraweu forest are illegal logging, forest cutting, hunting and gold-mine exploration.

Judul: Penyelesaian Numerik Persamaan Schrödinger untuk Molekul BaO dan SrO Menggunakan Model Potensial Morse
Abstrak: Morse potential is a potential model used to describe the behavior of a molecular vibration between atoms. This study aimed to obtain the value of the dissociation energy, the energy eigenvalues of each energy level, and describe the shape of the wave function of the molecule BaO and SrO on the vibrational state. Dissociation energy is calculated by adding the experimental dissociation energy and the ground state energy eigenvalues. Calculating the energy eigenvalues of the energy levels 0 to 4 using shooting method integrated with Numerov and Runge-Kutta method. Energy eigenvalues of each levels that calculated numerically having accuracy of 100% compared with the calculated analytically. The profil of wave functions accurately show the corresponding states and their normalized wavefunctions.
