Abstrak: This study conducted from April 2002 to June 2004. The purpose of the study was to analyze the life-supporting condition of Bawean deer habitat and the interaction between tbe community and the game sanctuary area and to formdate a dynamic model of Bawean deer population. The result of the study showed that the quality of one component of lifesupporting capacity, i.e. the stream water in the region of Bawean Game Sanctuary both in dry and rainy seasons, had met the requirement of drinking water for deer because it was of the third grade of water quality standard. However, the content of humus in the soil of savannah of Tanah Gresk, Langpelem, and Sumbedanas varied b m low to medium levels. The plant community in the Village of Kornalasa was different from those in the Villages of hdalut Barat and Patar Selamat, but the plant community in the last two villages (Pudakit Barat and Patar Selamat) was relatively the same. The production of grass on the Tanah Gresik Savannah in the dry season was 32.5 kg perhectare per day, while in the rainy season it was 84 kglhectare per day. Based the collected data, a structure of a dynamic model of bawean deer population can be formulated, consisting of 3 sub-models : a sub-model of deer population, a sub-model of greenery feed for deer, and a sub-model of community. The result of simulation showed that the highest population of bawean deer in the current condition (i.e. with 0.5 deer hunting per month and 27.5 kg of grass cutting per person per day on the effective habitat of 1200 hectare) would happen in 2015, reaching 1,142 deer. However, if hunting is at the rate of four deer per month, then the deer population will canthue to decrease and in 2016, there will be 165 deer left. A systemic approach can provide a long-term picture of pupuiation change of deer and it is useful for the development of the game sanctuary on the Bawean Island. Based on the observation of the components of deer habitat, it is recommended that intensive improvement and management be carried out both for the habitat and the community around the game sanctuary am. In order that the result of the study on the population change of deer couId be applied, it is necessary to do research on the population change of deer whose analysis uses the variables of habitat-infl uencing component.

Judul: Perencanaan Penangkaran Rusa Timor (Cervus timorensis de Blainville) dengan Sistem Farming : Studi Kasus di Penangkaran Rusa Kampus IPB Darmaga
Abstrak: Timor deer (Cervus timorensis de Blainville) is one of Indonesia wildlife species which population growth on natural habitat facing many threats as impact of human activities, like wild hunting and habitat destinction and fragmentation. Timor deer can be developed as livestock in the future its ability in difference geographic area of Indonesia. Farming system is appropriate model to be developed, because majority of Indonesian farmers ha ve about less than 1 hectares of farm area. The objectives of this research are: to analyse suitable location, to analyse breeding plan and economical aspect. The research was caried out in captive breeding field labratory of IPB Darmaga Campus. Equipments which have been used are: digital camera, rool meter, weighing-machine and a set of computer with design program. Materials which used are: map, timor deers and plastic bags. This research used field observation method, literature study and interview method. Pursuant to this research with based on bioecological condition, IPB captive breeding is suitable for timor deer captive location. Farm location was devideed into: headquarter zone 0,10 hectare (2,35%) and captive breeding zone 4,15 hectare (97,65%). Captive breeding management to be executed is farming system. Based on economic analysis, until 21,35% interest, captive breeding with farming system still give advantage if population size of parent stock in first year are 105, and 210 in second year and to be taken care until ninth year, with payback period 4,53 years.

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.
