Judul: Modeling wintering habitat distribution of migratory raptor “Oriental Honey-buzzards” based on satellite tracking data in West Java.
Abstrak: Raptors are at the top of the food chain, so their health depends on the health of the ecosystems they live in or migrate through. Thus, declines in raptor populations can indicate a problem in an ecosystem that raptors depend on. This study aims : 1) to build the distribution model of the OHB wintering habitat based on the data of satellite tracking in Talaga Bodas and surrounding areas; 2) to extrapolate the model for the entire province of West Java; 3) to analyze specific aspects of vegetation microhabitats in Talaga Bodas; 4) to develop wintering habitat management implications of OHB in West Java. This project was conducted in Talaga Bodas and surrounding areas then the model were validated in the other areas in West Java Province. Main methodology was combining satellite-tracking data of OHB with the GIS/remote sensing analysis, spatial modeling and vegetation analysis. Analyses were based on the comparison features (environmental variables) at the presence and pseudo-absence sites of OHB, which were detected from satellite-tracking data. Vegetation analysis to count Important Value Index and Diversity - Shanon Wiener Index in Talaga Bodas. The result, from 18 environmental variables, only 7 variables were detected as important variable for characteririzing the distribution of wintering habitat. Wintering habitat distribution model were predominantly influenced by slope 25%-40% (DS5), elevation 0-100 m (DE1), elevation 100-300 m (DE2), elevation >1000 m (DE5), forest (DFT), paddy field (DPF) and water body (DWB). Before the logistic regression model extrapolated in West Java, has been validated beforehand. Validation results showed that this model has an ommision error of 20,34%. 24 patches were detected from model extrapolation which is scattered in the region of West Java. The results of the vegetation analysis’s known that the core habitat biodiversity tend to have slightly less variable than the edge habitats. Results of this study suggested four implications for wintering habitat management of OHB.

Judul: Pengelolaan Lanskap Habitat Musim Dingin Sikep Madu Asia (Pernis ptilorhynchus) Berbasis Satellite Tracking di Kawasan Talaga Bodas, Jawa Barat
Abstrak: Oriental Honey Buzzard (OHB) (Pernis ptilorhynchus) is one of migratory raptor that had been satellite-tracked since 2003. One of area which chosen by OHB was Talaga Bodas, placed in West Java. The objectives of this study were to identify and to compare the core and edge landscape characteristics of OHB‟s winter habitat in West Java, to compare characteristics of OHB‟s winter habitat in West Java with South Kalimantan, and to obtain the landscape management plan of OHB‟s winter habitat in Talaga Bodas area. Principal Component Analysis (PCA) combined with Geographical Information System (GIS) was used to identify and to compare the landscape characteristics. The results of this study were defined by twelve principal components (PCs) and eleven PCs, which were explained by 76% and 76,3% of the data variance in landscape characteristics of core and edge habitats respectively. The basic characteristics of core and edge ii habitats in West Java were related to the nearest distance by semi-plain area (3-8 % slope), the nearest distance by open land, and the nearest distance by paddy field. The difference of core and edge habitats in West Java and South Kalimantan was the conservation areas, where conservation areas of South Kalimantan placed in core habitat, whereas conservation areas of West Java area placed in edge habitat. Landscape management of winter habitat based on period (short and long term) was planned, and the ecotourism based on raptor migration was developed in Talaga Bodas area.

Judul: Sintesis 1-Kloro-2-metoksi-6-propilnaftalena-1,3-dioksolana (1:1) sebagai Prekursor Asam (S)-(+)-(6-Metoksi-2-naftil)propanoat
Abstrak: Senyawa 1-kloro-2-metoksi-6-propilnaftalena-1,3-dioksolana (1:1) sebagai prekursor asam (S)-(+)-(6-metoksi-2-naftil)propanoat disintesis dari bahan awal 2-metoksinaftalena. Tahapan sintesis diawali dengan klorinasi menggunakan 2 jenis pereaksi klorinasi, yakni isosianurat terklorinasi dan NaOCl. Klorinasi dengan isosianurat terklorinasi berhasil menyintesis 1-kloro-2-metoksinaftalena sebagai produk monoklorinasi melalui pencirian dengan kromatograf gas-spektrometer massa (GC-MS). Nisbah konversi produk paling efisien diperoleh pada laju penambahan 2.5 mmol/jam. Sebaliknya, klorinasi dengan NaOCl menghasilkan produk triklorinasi. 1-Kloro-2-metoksinaftalena selanjutnya diasilasi dengan propanoil klorida, tetapi analisis dengan GC menunjukkan bahwa produk asilasi tidak terbentuk. Sistem bebas-air diperlukan untuk keberhasilan proses asilasi tersebut.
