Judul: Kondisi habitat dan sikap masyarakat terhadap konservasi Rafflesia micropylora Meijer di Taman Nasional Gunung Leuser
Abstrak: Rafflesia micropylora Meijer is one of its protected plant species because of the scarcity and endemic in the Indonesian tropical rain forest. One of R. micropylora habitats found in Gunung Leuser National Park (GLNP), Aceh Tenggara, Nanggroe Aceh Darussalam (NAD), is especially under the pressure and threat of human activity. Therefore, the presence of R. micropylora in nature must be preserved. The objective of this study was to determine the condition of R. micropylora, habitat conditions and communities attitudes to the conservation of R. micropylora. The expected benefits as input in the conservation efforts for R. micropylora in Southeast Aceh NAD GLNP. The research was conducted in Block Gurah Ketambe GLNP serve from June to August 2010. The data was collected by using purposive sampling method with a single plot of 1 ha. The measurement of knob conditions, biotic and abiotic conditions, and communities attitudes were done in the block. The results showed that the condition of R. micropylora was found one knob. The condition of vegetation in Block Gurah Ketambe GLNP included lowland forest vegetation which was dominated by Parashorea parvifolia species of Dipterocarpaceae. Canopy strata were A, B, and C with the coverage of title at 55.15%. R. micropylora grown on the host species Tetrastigma lanceolarium. The existing animals in this study are orangutans, wild boar, Capricornis sumatraensis, deer, and sun bears. Abiotic (physical) conditions R. micropylora habitat located at an altitude of 510 m.dpl with slope 0-45°. Soil has a pH neutral to slightly alkali with a texture-sandy clay loam with reddish-brown color. Daily temperatures are 27-28°C with a humidity of 85-97%. Community attitudes toward forest areas was that 30 respondents were more familiar with and know the information about R. micropylora from media and discussion of other people. Communities will support the conservation of R. micropylora although some have a little appreciation and don’t really feel the presence of R. micropylora. The habitat of R. micropylora was disturbed by activities of the jungle in form of path tracking and animal observation point. Management activities of R. micropylora habitat was considered ineffective related to the encroachment of forests and cutting T. lanceolarium. The results mentioned above describe the condition of R. micropylora, which was in danger due to a variety of activities. The R. micropylora habitat was in the lowland forest vegetation types dominated by the species P. parvifolia. Public attitudes toward forests usually support the conservation of R. micropylora, it was necessary to give information to the communities so that they take care and monitor the population and R. micropylora habitat.

Judul: Habitat Characteristics of Rafflesia rochussenii Teijsm. et Binn. in Cimande Resort, Gunung Gede Pangrango National Park
Abstrak: Rafflesia rochussenii is a rare and protected plant species. This species is found in Cimande Resort, Gunung Gede Pangrango National Park, Bogor, West Java. The purpose of this study is to describe the habitat characteristics of Rafflesia rochussenii in Cimande Resort, both biotic and abiotic components, and to explain its management program. The method used is purposive sampling with circular plots with a radius of 17.8 m. Literature study was done to find supporting data. Results identified 57 Rafflesia individuals were found consisting of alive and dead flowers as well as alive and dead buds. The host was Tetrastigma leucostaphylum. The dominating species at the tree, sapling, seedling and undergrowth level were Schima wallihcii, Castanopsis acuminatissima, Aspnlenium nidus, and Cinchona pubescens, respectively. Six species of animals were identified. Rafflesia habitat is found in the altitude of 840-1,360 masl, a slope of 10% -88%, average temperature of 19°C and relative humidity ranging from 80-90%. Soil pH ranges from 5-6.5, soil color is reddish brown to yellow. Leaf Area Index value ranges from 1.85-2.11. Management done by the National Park is inventory and monitoring.

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.
