Judul: Faktor-Faktor Penyebab Kepunahan Banteng (Bos javanicus) di Cagar Alam Leuweung Sancang Jawa Barat
Abstrak: Banteng (Bos javanicus) is one of wildlife species that is categorized into the conservation status of "Endangered" which its habitat and population continue to decline to extinction even in natural reserve such as Leuweung Sancang Natural Reserve. Habitat and population of banteng currently just located in national park which is wide area and intensive management with other protected areas including Leuweung Sancang Natural Reserve. The objective of this research is to anlyze the extinction factors of banteng in Leuweng Sancang Natural Reserve by identifying and analyzing the population, distribution, habitat, socio-economic activities of communitie and area management system. To identify ecology, socio economic and management condition with literature study and interview. The research analysis is reliability and validity instrument, spatial, qualitative, quantitative and correlation factors. Wide and shape area, boundary area, area status, PMP activities, stakeholders, community perception and community interaction are all factors than can affect to banteng extinction in Leuweung Sancang Natural Reserve. Correlation factors are (a) wide and shape area (WSA) with community interaction (0.540350); (b) PMP activities with community interaction; (c) boundary area with area status (0.531250). The extinction factors of banteng are illegal hunting that impact of 3 factors, are: (1) habitat degradation especially less maintenance of grazing area and the elongated shape of Leuweung Sancang Natural Reserve did not support banteng population, (2) less of management intensity, (3) local people negative perception for banteng existence.

Judul: Analisis Pla Penggunaan Ruang Banteng (Bos javanicus d'Alton 1823) di Cagar Alam dan Taman Wisata Alam Pangandaran Jawa  Barat
Abstrak: Banteng is the one of animal which is being extinction (endangered) In Java, banteng distribution limited in several conservation area including Pangandaran Nature Reserve and Pangandaran Nature Recreation Park. The population in this site is fluctuate, in 2007 there's only one adult female banteng, Harm condition brought BKSDA Jawa Barat II as the role play key to make a plan for reintroduction the male banteng into the area, in order to increase the population. Because of that, it is need to conduct a research ecological of the banteng, one of them is space utilization pattern which is give about banteng's existence and activities in several types of vegetation. The data is collected including 1) the type of activity, 2) position and time of activity and 3) habitat characteristic. Behacioral obseravtion is done directly, following the movement of banteng , within seven times replilation. Vegetation analysis is done with transec method.

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.
