Judul: Model Kesesuaian Habitat Tarsius (Tarsius Sp.) Di Hutan Lambusango Pulau Buton Provinsi Sulawesi Tenggara
Abstrak: Tarsius (Tarsius spp.) adalah salah satu primata endemik Pulau Sulawesi yang juga tersebar di pulau-pulau sekitarnya. Hingga saat ini, terdapat lebih dari 16 populasi tarsius tersebar di Sulawesi dan dapat digolongkan menjadi spesies berbeda namun, hanya 9 spesies yang telah teridentifikasi. Hutan Lambusango adalah salah satu lokasi penyebaran tarsius di Pulau Buton. Lokasi ini merupakan hutan hujan dataran rendah tropis dengan gangguan antropogenis yang cukup tinggi terutama berasal dari tambang-tambang yang berada di sekitar kawasan hutan. Penelitian ini bertujuan untuk (1) mengidentifikasi karakteristik habitat tarsius di Hutan Lambusango, (2) menganalisis hubungan antara komponen habitat dan keberadaan tarsius di Hutan Lambusango dengan menggunakan GIS, dan (3) menduga luas habitat yang dapat mendukung populasi tarsius di Hutan Lambusango dengan menggunakan GIS. Penelitian dilaksanakan di dalam Hutan Lambusango yang terdiri atas Cagar Alam Kakinauwe dan Suaka Margasatwa Lambusango. Pengambilan data lapangan dilakukan pada bulan Juni-Agustus 2014. Data yang dikumpulkan antara lain adalah lokasi tidur tarsius, kondisi fisik habitat, kondisi vegetasi dan potensi pakan di setiap lokasi tidur. Setiap lokasi tidur yang ditemukan ditandai dengan menggunakan GPS. Pengumpulan data kondisi vegetasi menggunakan metode analisis vegetasi. Sedangkan untuk pengambilan data serangga dilakukan dengan metode perangkap cahaya (light trap) selanjutnya diidentifikasi di Laboratorium Taksonomi Serangga, Departemen Proteksi Tanaman, Fakultas Pertanian, Institut Pertanian Bogor. Analisis data dengan menggunakan Principal Component Analysis (PCA) untuk mengetahui bobot dari masing-masing variabel habitat sehingga dapat diketahui variabel habitat mana yang paling berpengaruh pada penyebaran tarsius. Hasil dari analisis PCA tersebut kemudian dianalisis secara spasial menggunakan GIS. Sebanyak 42 lokasi tidur tarsius teridentifikasi di Hutan Lambusango dan pada umumnya menempati wilayah perbatasan hutan. Jenis-jenis sarang yang teridentifikasi diantaranya adalah pohon Ficus spp., lubang-lubang batu, semak-semak yang dikelilingi liana, rumpun pandan, pohon tumbang yang diselimuti liana dan pohon wola (Vitex cofassus). Berdasarkan analisis PCA, terdapat total 7 variabel habitat yang memengaruhi kehadiran tarsius diantaranya adalah, nilai jarak dari batas hutan, jarak dari jalan, ketinggian, arah kelerengan, NDVI, FCD, dan keanekaragaman serangga. Luas Hutan Lambusango yang sesuai untuk habitat tarsius adalah 31 520 ha atau 82.96% yang terdiri dari 19.75% (24 017.70 ha) yang memiliki kelas kesesuaian sedang dan 63.21% (7 502.79 ha) yang berada pada kelas kesesuaian tinggi.

Judul: Karakteristik Habitat dan Populasi Tarsius (Tarsius fuscus Fischer 1804) di Resort Balocci Taman Nasional Bantimurung Bulusaraung Sulawesi Selatan
Abstrak: Tarsier (Tarsius fuscus Fischer 1804) is one of endemic primates of South Sulawesi, which has been protected by Government Regulation No. 7 of 1999. This species is categorized as vulnerable by the International Union for Conservation of Nature (IUCN) Red List and on Appendix II of the Convention on International Trade in Endangered Species (CITES). The objective of this study were (1) to identify habitat characteristics including physical condition, composition and structure of vegetation and food (insects) availability, (2) to examine the distribution and population of tarsier. This study was conducted in Resort Balocci, Bantimurung Bulusaraung National Park from May to July 2011. The data collected consisting composition and structure of vegetations, the number and diversity of insects, distribution and population size of tarsier. Characteristic of vegetations data was collected using a single swath method. Collection of insects as potential food of tarsier was taken by light trap method and identified in Laboratory of Insect Taxonomy, Plant Protection Department, Faculty of Agriculture, Bogor Agricultural University. Population size was determined using concentration count method around the nesting trees of tarsier. The observations were started at 05.00-07.00 and 16.30-18.00. This study showed that tarsier inhabited secondary forest, plantations and vegetation near the settlement (yard). Nesting trees of tarsier could be observed in the crevices of the rocks, in the cracks of ficus trees (Ficus spp.), sugar palm tree (Arenga pinnata) and bamboos (Bambusa spp.). In addition to the nesting trees, there are Macaranga hispida and Artocarpus altilis. The secondary forest has more insects than plantations and vegetation near the settlement. A total of 112, 89 and 80 individuals of insects recorded in the secondary forest, vegetation near the settlement and plantation respectively. A total of 13 groups consisting of 44 individuals of tarsiers recorded in the study area. There were 31 individuals in secondary forest, 9 individuals in plantation and 4 individuals in vegetation near the settlement. Population densities of tarsier were 151 individuals/km2 in the secondary forest, 36 individuals/km2 in the plantation and 23 individuals/km2 in the vegetation near the settlement.

Judul: Synthesis of Molybdenum Trioxide (MoO3) by Electrochemical Method for Electrochromics Application
Abstrak: Molybdenum trioxide (MoO3) thin films have been deposited on glass substrates by electrochemical method using ammonium heptamolybdate tetrahydrate ((NH4)6Mo7O244H2O). The films were deposited onto glass substrates as the control temperature at 25○C and annealing treatment at 350○C for 30 mins. The MoO3 thin films were investigated by UV-Vis, X-ray diffraction techniques (XRD), Scanning Electron Microscopy (SEM). The JCPDS card show that orthorhombic MoO3 (α- phase) has been formed. Molybdenum trioxide MoO3 formation was also confirmed by JCPDS card no. 35-0609. The SEM photographs revealed that the spherical and rod-like morphology and their grains size increased with increasing of heating temperatures. The measurement results show that the MoO3 thin film prepared at 350°C transmited about 80% of the visible spectrum. The effect of different heat treatments on surface morphology, thickness and optical properties of the films are discussed in this thesis.
