Judul: Tingkah Laku Kancil (Tragulus javanicus) Yang Berhubungan Dengan  Aktivitas Makan Di Penangkaran
Abstrak: Mouse deer (Tragulus javanicus) is a wild animal with the status of protected based on the Government Regulation No. 7, 1999. Mouse deer population has decreased and could be extinct in the future. Captive breeding is one of the ex situ efforts to preserve this wild animal population. This research was conducted in September- December 2009 in Small Mammal Captivity, Zoology Division, Research Center for Biology, LIPI, Cibinong. A female mouse deer aged three years and had been captivated for 3 years was used as the observed. Variables measured were daily activities (eating, drinking, defecating, urinating, locomotion, grooming, ruminating, and resting) and selection of feeds: Ipomea batatas, Sechium edule, Psidium guajava, Luffa acutangula, Lagenaria leucantha, Phassolus calcaratus, Musa sp.), Phylanthus urinaria, Phaseolus radiatus, Brassica chinensis, Mikania cordata, and Phaseolus sp. Observations were carried out for 24 hours, from 06.00 am until 06.00 am the day after. Each periode was divided into 15 minutes observation intervals. One-zero sampling method was used in the data collecting then the data were analysed descriptively. Mouse deer prefered Ipomea batatas, Sechium edule, Psidium guajava, Luffa acutangula, Lagenaria siceraria, and Phassolus calcaratus, as feeds in the day light and Musa sp., Phylanthus urinaria, Phaseolus radiatus, Brassica chinensis, Mikania cordata, and Phaseolus sp. in the night. The percentage of mouse deer’s activities are 36,371 % resting, 15,312% ruminating, 15,558% locomotion, 13,814% grooming, 12,603% eating, 3,284% urinating, 3,058% defecation and 0% drinking. The captive should be given hiding place to acomodate resting, ruminating, and grooming activities.

Judul: Perilaku Dan Pola Konsumsi Rusa Timor (Rusa timorensis de Blainville 1822) Di Penangkaran Akibat Pemberian Pakan Oleh Pengunjung
Abstrak: Timor deer (Deer timorensis) which known as deer java is native fauna indonesia which much found in ex-situ. Deer be an attraction object of tourism in captivity. The purpose of this research is identify deer feed that given by visitors in captivity, and identity the whereabouts changes in the behavior patterns of consumption and feed timor deer cause the provision of feed by visitor. The identified feed given by visitors to deer are about 89% convolvulus, 8% carrots, 2% the leaves, 1% wild grasses. Feed which gave great influence in order to meet the basic needs of a deer is convolvulus containing 8,93% protein and carrots containing 19,99% protein. Result of statistic test by used chi-square indicates that no real influence on the behaviour and consumption patterns of deer in captivity, but nominally showed the increase and decrease of presentation. Based on observations, behaviour that increase are food and social, whice breaks, locomotion, and rumination behavior decreased.

Judul: Membran Komposit Polivinil Alkohol-Zeolit Berporogen Pluronik Untuk Pervaporasi Etanol
Abstrak: Membran komposit polivinil alkohol (PVA)-zeolit dibentuk dengan menambahkan pluronik sebagai porogen untuk aplikasi pervaporasi etanol. Zeolit yang digunakan adalah zeolit alam yang berasal dari Cikalong, Tasikmalaya. Membran disiapkan melalui proses fase inversi. Komposisi pembuatan membran komposit PVA-zeolit adalah 2.0 g PVA:0.1 g zeolit:0.3 g pluronik. Zeolit yang digunakan memiliki nilai kapasitas tukar kation 183.41 mg ek/100 g hasil aktivasi menggunakan NaOH 3 M. Keberhasilan kinerja membran ditentukan oleh peningkatan konsentrasi dan faktor separasi yang dievaluasi menggunakan kromatografi gas. Konsentrasi etanol yang didapat dari hasil pervaporasi meningkat dari konsentrasi 70% menjadi 73.66% dan faktor separasi memiliki nilai 1.20. Analisis morfologi pada penampang melintang membran menggunakan mikroskopi elektron payaran menunjukkan membran yang terbentuk adalah membran asimetris.
