Judul: Potency of The Development of Buffalo in Bojong and Cibunar Village of Garut Regency.
Abstrak: In the development of livestock in Garut Regency, it is important to understand factors influencing its improvement including land use, feed availability, environment, animals, and social cultural of the local farmers. The aim of this study was to assess the potency of buffalo development in two villages of Garut namely Bojong and Cibunar. Each village has its own characteristics as follow Bojong is located at the altitude of 1100 m above sea lives with greater area of rice fields, and mechanization has been existed in the village; where as Cibunar is located at the altitude of 600 In above sea level, and buffalo are mostly used as draught animal for ploughing rice fields.

Judul: Potency of Ruminant Forage in Karacak Village, Leuwiliang, Bogor.
Abstrak: The increasing of human population may cause the raising of food demand especially animal protein. Ruminants are potential livestock to be developed, because it could contribute mostly of meet supply. Therefore, it is required a priority zone to be developed as animal fanning area, in Indonesia. where the animal farm distribution is not spread evenly. The first step of animal zone is acquainted with each potential area that determined a number of animals which still can be developed in an area. This research was aimed to estimate potency forage by Nell and Rollinson method, and SWOT analysis to provide the advantage in fonn of information to plan the area and arrange development direction policy. Data were collected from two sources, they were (I) primary data from direct interview with the farmers, officials, and associate institution with structured questionair contribution, (2) secondary data from Villages Profile, Sub District Profile, Agricultural and Bogor Animal Farm Agency and associate institution supported this research. Where as the analysis and data were processed by using Nell and Rollinson method., botanical analysis, and SWOT analysis. The result of Nell and Rollinson method showed that Karacak village had 597,748 ton/year for forage potential, thus it still retained animal for 134 Animal Unit Area development strategy for animal farm in Karacak village was be set up on on the basic of SWOT analysis, such diversification in which had some treats, but internally still had strength. Key word : Forage, SWOT, Karacak village

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.
