Judul: Perubahan Penutupan Lahan dan Faktor Penyebabnya di Taman Nasional Rawa Aopa Watumohai, Provinsi Sulawesi Tenggara.
Abstrak: Land cover change is a common phenomenon faced is the conservation area management in Indonesia, including Rawa Aopa Watumohai National Park. This research aims to analyze the land cover change and it’s causing factors. The data carried out on August 2014 using Geographic Information System (GIS) including groundcheck and respondent interview. This research resulted the land cover change from 1981-2013. The most changing land cover is the lowland mountain forest which was converted is to dryland agriculture with 7 553.58 hectare of total area in 1981-2001. Land cover change is caused by economic needs along with reform momentum in 1997, weak law enforcement, lack of the number of personnel, lack of local government support, and landuse needs supported by capital owner.

Judul: Perubahan Tutupan Lahan di Taman Nasional Bukit Barisan Nama NIM Selatan Provinsi Lampung
Abstrak: National Park is a conservation nature area which has function to protect life support system, maintain flora fauna and its ecosystem, which is managed by zonation system. The zonation can be divided into core zone, utilization zone and other based on the necessity. However, National Park is still facing problem such as illegal poaching, illegal logging, forest encroachment, and agrarian conflict to national park border. One of national park which has such kind of problem is Bukit Barisan Selatan National Park. The research is aimed at investigation of land use/land cover and its causes. After conducted the research by using GIS and interviewed some participants, the result showed that forest cover is decreased during period of 1991 to 2013. This decrease is due to forest encroachment, in which forest was converted into coffee plantation. In fact, it was happened before the National Park establishment.

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.
