Judul: Parameter Demografi dan Penggunaan Ruang Vertikal Lutung Jawa (Trachypithecus auratus Geoffroy 1812) di Resort Tamanjaya Taman Nasional Ujung Kulon
Abstrak: Demography parameter of ebony leaf monkey at Tamanjaya Resort of Ujung Kulon National Park wasn’t knew. Demography parameter was important component to the studied of population. The purposed of this study was to estimated demography parameter and indentification of used spatial vertical. The method used of demography parameter was consentration count method. The continuous recording method used for the analysis of the used of space, and method used in the analysis vegetation was plot method. Result of the study showed there were 17 individual of 3 grups, with composision 5 childerns, 4 juvenliles, 3 adult males and 5 adult females. Sex ratio from 3 groups were 1:1.6. Birthrate were 0.29. The highest mortality occured from juvenile to adult was 0.66. Ebony leaf monkey in Tamanjaya Resort used B and C level.

Judul: Pemodelan Spasial Kesesuaian Habitat Lutung Jawa (Trachypithecus auratus Geoffroy, 1812) di Resort Rowobendo Taman Nasional Alas Purwo
Abstrak: One of the Ebony leaf monkey habitat is Rowobendo Resort in Alas Purwo National Park. The research objectives are mapping habitat suitability, to identifying factors which highly influence habitat suitability and to determining area of Ebony leaf monkey habitat suitability. Ebony leaf monkey habitat suitability mapping was initiated by collection data, such as digital map, data survey and literature. This mapping was based on some habitat variables, namely NDVI, altitude, slope, distance from road, distance from river, and distance from village. The value from each points then being analyzed by using principal component analysis (PCA) to get the weight of each variable. Habitat suitability model of ebony leaf monkey was Y = (1.189*FkNDVI) + (2.546*Fkaltitude) + (1.058*Fkslope) + (1.058*Fkriver) + (2.546*Fkroad) + (2.546*Fkvillage). The habitat suitability map were reclassified into three suitability classes. The result showed that there were 953.60 ha of low habitat suitability, 1899.35 ha of medium habitat suitability, 859.43 ha of high habitat suitability. The habitat suitability map could be accepted by showing the validation about 87,10%.

Judul: Sintesis kompleks salen Cu/Ni sebagai katalis oksidasi gliserol
Abstrak: Biodiesel sebagai salah satu alternatif pengganti minyak bumi telah menghasilkan produk samping berupa gliserol kasar. Salah satu cara pemanfaatan adalah dengan mengoksidasinya menjadi dihidroksiaseton menggunakan kompleks senyawa salen yang telah dihidrogenasi dengan logam atom pusat Cu dan Ni. Katalis yang dihasilkan dicirikan menggunakan spektrofotometer inframerah transformasi Fourier dan spektrofotometer serapan atom. Kinerja kedua katalis dalam mengoksidasi gliserol telah dibandingkan dengan baik dalam penelitian ini. Oksidasi gliserol dilakukan dengan tambahan katalis sebanyak 5 mol% gliserol dalam campuran gliserol-asetonitril. Reaksi dilakukan dengan melewatkan gas oksigen selama 4 jam pada suhu ruang dalam campuran tersebut. Hasil oksidasi dianalisis menggunakan kromatografi cair kinerja tinggi. Puncak kromatogram dari hasil oksidasi yang muncul setelah menit ke-9 menunjukkan terjadinya perubahan gliserol. Produk oksidasi gliserol diduga memiliki gugus fungsi keton karena nilai Rf-nya lebih besar daripada gliserol, yang menandakan senyawa tersebut lebih nonpolar daripada gliserol. Kromatogram yang diperoleh menunjukkan bahwa aktivitas katalis Cu(salen) mengoksidasi gliserol lebih baik ditinjau dari rendemen produk yang dihasilkan dibandingkan dengan Ni(salen). Oksidasi baik dengan Cu(salen) maupun Ni(salen) menghasilkan satu produk oksidasi.
