Judul: Daily Behavior and Space Utilization of Timor Deer, Sambar Deer and Bawean Deer in Captive Breeding
Abstrak: Penangkaran rusa timor (Rusa timorensis), rusa sambar (Rusa unicolor), dan rusa bawean (Axis kuhlii) dilakukan secara bersama di dalam satu areal kandang yang sama, seperti yang dilakukan di Penangkaran Rusa, Hutan Penelitian Dramaga, Bogor. Ketiga jenis rusa ditangkarkan bersama-sama di dalam satu areal kandang pedok terbuka berukuran 38 x 38 meter. Data perilaku harian dan penggunaan ruang dikumpulkan dengan metode focal animal sampling. Untuk mengidentifikasi penggunaan ruang, maka ruang kandang dibagi menjadi tiga zona yang berbeda (Zona Depan 1, Zona Tengah 2, Zona Belakang 3). Rusa timor menunjukkan perilaku makan (ingestif) lebih sering (37,32% hari kerja dan 36,06% pada akhir pekan) dibanding rusa sambar (25,35% akhir pekan dan 26,63% hari kerja) dan rusa bawean (17,68% akhir pekan dan 18,89% hari kerja). Terkait penggunaan ruang, ketiga jenis rusa lebih sering menggunakan zona 1 dibanding dengan kedua zona lainnya, berturut-turut yang paling sering adalah rusa bawean (73,50%), rusa timor (71,34%) dan rusa sambar (62,46%)., The captivity of timor deer (Rusa timorensis), Sambar deer (Rusa unicolor) and Bawean deer (Axis kuhlii) is carried out together in the same enclosure area, as was done in Deer Captivity, Dramaga Research Forest, Bogor. The breeding of timor deer (Rusa timorensis), sambar deer (Rusa unicolor), and Bawean deer (Axis kuhlii) is carried out together in the same enclosure area, as was done in Deer Breeding, Dramaga Research Forest, Bogor. The three types of deer are bred together in an open pedok cage measuring 38 x 38 meters. Daily behavior and space use data were collected using the focal animal sampling method. To identify space usage, the cage space is divided into three distinct zones (Front Zone 1, Middle Zone 2, Rear Zone 3). Timor deer show eating behavior (ingestive) more often (37,32% on weekdays and 36,06% on weekends) than Sambar deer (25,35% on weekends and 26,63% on weekdays) and Bawean deer (17, 68% weekends and 18,89% weekdays). Regarding the use of space, the three species of deer use zone 1 more often than the other two zones, respectively Bawean deer (73,50%), Timor deer (71,34%) and sambar deer (62,46%) are the most frequent.

Judul: Welfare Management and Health Status of Deer at Captivity Hutan Penelitian Dramaga, Bogor
Abstrak: Keberadaan rusa timor (Rusa timorensis), rusa sambar (Cervus unicolor), dan rusa bawean (Axis kuhlii) di alam perlu dipertahankan. Salah satu lembaga yang mendukung kegiatan konservasi eksitu tersebut adalah Penangkaran Rusa Hutan Penelitian Dramaga, Bogor. Penelitian ini dilakukan dengan menilai penerapan manajemen kesejahteraan satwa dan status kesehatan satwa. Data kesejahteraan rusa diperoleh melalui observasi lapang, wawancara dan pengisian kuisioner. Status kesehatan rusa berdasarkan kejadian infeksi cacing saluran pencernaan (helminthosis) diperoleh dengan melakukan pengambilan sampel feses, kemudian dianalisis secara mikroskopis melalui metode McMaster, flotasi sederhana dan saringan bertingat modifikasi. Hasil penelitian menunjukkan bahwa pengelolaan kesejahteraan rusa di penangkaran rusa Hutan Penelitian Dramaga tergolong “baik” dengan skor tingkat kesejahteraan satwa mencapai 73,03. Telur cacing parasit yang ditemukan yaitu Trichuris, Strongyloides dan Trematoda yang menginfeksi rusa, dengan derajat infeksi TTGT tergolong dalam kategori rendah., The existence of timor deer (Rusa timorensis), sambar deer (Cervus unicolor), and bawean deer (Axis kuhlii) in the wild needs to be preserve. One of the responsible institutions in ex-site conservation activities is deer captivity of Dramaga Research Forest, Bogor. The study was conducted to assess the implementation of animal welfare and animal health status. Data of deer walfare management was obtained by field observations, interview, and filling the questionnaire. Deer health status based on the gastrointestinal endoparasites infection (helminthosis) was obtained by collected faecal sample, then it was analyze with microscopic evaluation by McMaster, simple flotation and modification of sedimentation technique. The study shows that deer welfare management in deer captivity of Dramaga Research Forest was classified as a “good” with a score of animal walefare’s level up to 73,03. All animals were parasitized by Trichuris, Strongyloides, and Trematode with low infection intencity level EPG.

Abstrak: Solid polymer electrolyte can be classified as a solid material that has the ability to conduct electric current by the movement of ions and has the same functions as an electrolyte solution. Polymer electrolyte film based on chitosan/PEG+KCl have been produced. The process of making is done by mixing a solution of acetid acid with chitosan, PEG and Potassium Chloride (KCl), polymer electrolyte were obtained by the casting technique. Polymer electrolyte with good ionic conductivity properties were characterized by FTIR analysis for the identification of the functional group. The results of FTIR analysis indicates that complexes of polymer electrolyte have formed. The best ionic conductivity values of 5.786 x 10-6 Scm-1 were obtained for the sample containing 45%wt of KCl. Activation energy obtained by using Arrhenius plot, activation energy from polymer electrolyte film with good conductivity is 0.270 eV.
