Judul: Penggunaan Ruang Kandang Berdasarkan Perilaku Berang-berang Cakar Kecil (Aonyx cinereus, Illiger 1815) di Pusat Penyelamatan Satwa Cikananga
Abstrak: Take a rest, play arround, and eat are of the most common behaviours encountered in both male and female otter. In contrast, the least common one are keeping others clean and avoiding conflict. The cage chamber of otter consisted of three main grids which function as the center of their whole activities, i.e., grid five, eight, and two. Those three grids had the essential components supporting the otter behavior to live as in its native habitat. Grid one and three were of the least often visited grids because they have coarse surface and messed by the remain material during cage building. Behavior frequency calculation in a grid on cross table showed the same result with Duncan analysis test, which explain that there was at least one behavior having the most significant value compare to other behaviors. This result indicates that the choosing of a grid for animal is related to their certain behavior supporting to the applied grid.

Judul: Penggunaan Ruang berdasarkan Perilaku Bergerak Owa Jawa (Hylobates moloch) di Pusat Rehabilitasi Primata Jawa, Ciwidey, Jawa Barat
Abstrak: Owa jawa (Hylobates moloch) termasuk ke dalam famili Hylobatidae. Perilaku bergerak owa jawa dibedakan menjadi empat, yaitu brachiate (brakiasi), climbing (memanjat), bipedal (berjalan atau berlari), dan leaping (melompat). Penggunaan ruang oleh satwa liar menunjukkan interaksi antara satwa dengan habitatnya. Penelitian ini bertujuan mengidentifikasi perilaku bergerak dan penggunaan ruang oleh owa jawa sebagai salah satu aspek kesiapan pelepasliaran. Subjek yang diamati terdiri dari dua pasang owa jawa dewasa. Metode yang digunakan adalah focal animal sampling. Pengamatan dilakukan selama 104 jam. Hasil pengamatan menunjukkan perbedaan pergerakan dominan di antara keempat individu. Brachiate dominan dilakukan oleh individu Acoy (♀) dan Iwan (♂), sedangkan bipedal dominan dilakukan oleh individu Kimba (♀) dan Douglas (♂). Berdasarkan uji t, jenis kandang memengaruhi pergerakan pada owa jawa. Owa jawa Pusat Rehabilitasi Primata Jawa sudah memenuhi salah satu kriteria pelepasliaran, yaitu berada pada bagian teratas kandang dan tidak pernah tidur di lantai kandang.

Judul: Metil Ester Gondorukem sebagai Kandidat Bahan Bakar Nabati
Abstrak: The objective of this research is to produce ester of rosin distillate using methanol and H2SO4 (pa) as a catalyst. The result showed an optimum yield of methyl ester was 88.5% at an operating condition of 1.2 mL catalyst in 1.5 hours. The infrared spectra showed that carboxyl groups was replaced by C=O ester group, proofing that the rosin distillate was esterified. Furthermore, the gas chromatography-mass spectrometer spectra showed that the resin acids consists of ester derivates of abietic acid, sandaracopimaric acid, dehidroabietic acid, isopimaric acid, palustric acid. Based on SNI 04 -7182-2006, the kinematic viscosity at 40ºC (4.2 mm2/s), cloud point (-18ºC), total sulfur (67 ppm), acid number (0.1 mg-KOH/g), iodine number (12.8%), and total alkyl ester (99.8%), the methyl ester of pine rosin would be feasible to be used as a biodiesel material. The flash point was considered too low for biodiesel, but would be suitable f or biogasoline.
