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.

Abstrak: Penelitian dilakukan pada bulan September 2006 sampai Juni 2007. Tujuan penelitian adalah untuk menganalisis komponen daya dukung habitat gajah, mengetahui tekanan penduduk dan persepsi masyarakat pada kawasan habitat gajah, dan menyusun pemodelan dinamika populasi gajah Sumatera. Hasil penelitian menunjukkan bahwa penutupan lahan pada kawasan habitat gajah terbagi atas 6 (enam) tipe; hutan primer 1375,47 ha (20,04%), hutan sekunder 3375,09 ha (49,16%), lahan terbuka 688,74 ha (10,03%), semak belukar 775,35 ha (11,29%), kebun masyarakat 170,56 ha (2,48%), dan padang rumput 479,79 ha (6,99%). Topografi mulai dari 50 dpl sampai dengan 82 dpl, sedangkan kelerengan dari datar hingga bergelombang dengan kondisi suhu sekitar berkisar antara 28oC -30oC.

Judul: Pembuatan dan Karakterisasi Lapisan Tipis Copper oxide (CuO) Sebagai Sensor Gas
Abstrak: Lapisan tipis Copper Oxide (CuO) adalah bahan scmikonduktor yang memiliki sirat sangat scnsitif tcrhadap gas. mcngingat bahan tcrscbut sangat mud-ah mcngabsorpsi gas. DCllgan absorpsi gas ini akan l11crubah resistivitas lapisan tipis tersebut. Dalmn pcmbuatan.lapisan (ipis ini, lllclodc yang digunakan adalah metodc Dcposisi Fasa Cair (Liquid Phase Deposition) yaitu dengan mencmnpurkan 100 ml larutan Copper Sulphal (CuSO, 1I2H,O) 1M dengan 50 ml ammonium 25 %, Kemudian dicuplik 6ml dan dimasukkan ke dalam wadall yang telah terisi aquades 60 ml dan substrat pada dindingnya, kemudian diaduk dengan slirier dan dipanasi pada suhu 75°C selama 1 jam, Pendeposisian ini dilakukan sebanyak 4 kali. Hasil karakterisasi XRD memperlihatkan puncak-puncak CuO yaitu berada pada 28 = 35,306; 38,502; 61.475; 65,538 dengan masing-masing d = 2,5400: 2,3362: 1.5071; 1.4231.
