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: Aplikasi SIG untuk analisis distribusi populasi harimau sumatera (Panthera tigris sumatrae, Pocock 1929) dan satwa mangsanya di Hutan Blang Raweu, Kawasan Ekosistem Ulu Masen, Aceh
Abstrak: Very little information is known of the distribution of Sumatran tiger and their prey species in Ulu Masen Ecosistem . Ulu Masen area is one of 18 Sumatran tiger’s population determining area which was appointed by Forestry Ministry in Sumatra for the implementation of Tiger Strategy and Action Plan at 2007. It was acknowledeged that Sumatran tiger existed at Ulu Masen, however, there was no any information on their population. This research was doing to support the government programs to determine the sumateran tiger population. This research was done from December 2009 until Mei 2010 in Blang Raweu Forest and its surrounding area in Ulu Masen ecosystem in Pidie and Pidie Jaya province Aceh. Based on the land cover, Blang Raweu Forest consisted 3 types, lowland tropical forest, mountain tropical forest and high mountain tropical forest. It ranging from lowland forest, hills forest, and mountain forest. The Data was taken by Random Camera Trap Methode and the prey population was analyzed based on the speed moving of the species. The tiger distribution was analyzed by overlaying the meeting point and the map of land cover type, forest type by the height, slope, grassland, river, settlement, and human activities in the area. Based on the tiger and prey distributionanalisys by using GIS, The tiger distribution was followed the prey. It was saw from the daily activity types and they prey bassed on the tiger and pery distribution maps. The primary factor in prey distribution wass feed, salt lick, and water, so it directly influence the tiger distribution. The other factors such as land cover, slope, altitude, human activity and the settlement which have different influence to the every animal. Estimated population based on CAPTURE (X±SE) program with the model mh was 6±2.45 individu. Meanwhile the tiger density is around 2-8 individu/100 km2 with the accuracy of about 95%. The primary prey in this area was Sambar deer, deer, and beard pig. Number of Sambar deer and deer could be estimated. There were 75 individu/100 km2 of sambar deer with 1:1 sex ratio.

Judul: Desain Gerbang Logika Kuantum Fredkin Multi- Kontrol Berbasis Gerbang Toffoli Melalui Superposisi Gerbang Elementer
Abstrak: Gerbang Fredkin dapat dimanfaatkan sebagai sel pembangun rangkaian fulladder untuk proses komputasi. Karena sifatnya yang reversibel, gerbang tersebut dapat dibuat dari sususan gerbang-gerbang elementer dengan basis gerbang Toffoli. Pada penelitian ini, penulis mencari desain dari gerbang Fredkin multi-kontrol berbasis gerbang Toffoli dengan mengkombinasikan tiga jenis gerbang elementer, yaitu CNOT, CV, dan CV†. Penelitian ini juga memperhitungkan jumlah gerbang elementer yang digunakan (quantum cost) dan jalur tambahan (ancillae input) dari desain-desain gerbang Fredkin yang dihasilkan. Dari hasil penelitian ditunjukkan bahwa gerbang Fredkin multi-kontrol dapat dibentuk oleh susunan tiga gerbang Toffoli multi-kontrol. Kemudian, gerbang-gerbang tersebut dapat direkonstruksi menjadi susunan gerbang-gerbang elementernya. Jumlah quantum cost dan ancillae input akan semakin besar seiring bertambahnya jumlah kontrol yang digunakan.
