Judul: Keberhasilan Reproduksi Tapir Asia (Tapirus indicus) Di Kebun Binatang Di Dunia
Abstrak: The aim of this study was to analyze reproduction datas of malayan Tapir (Tapirus indicus) which spread in the zoos world wide and recorded in International Malayan Tapir Studbook which were marriage season pattern, amount of birth, offspring survival, and life expectation. Tapirs recorded in International Malayan Tapir Studbook until July 2009 were 921 heads, with tapirs bornt in conservation were 540 heads. Cubs were born all year round without following certain season (nonseasonal). The result showed that tapir has low dead give-birth level (stillbirth 0,0-7,93%) and high give-birth potention (1 head every 2 years) so the population can be increased by good management practices.

Judul: Perilaku Beranak pada Tapir Asia (Tapirus indicus) di Taman Safari Indonesia Jawa Barat.
Abstrak: Penelitian ini bertujuan untuk mengamati tingkah laku beranak pada tapir asia (Tapirus indicus). Tingkah laku diamati melalui rekaman CCTV kandang dengan metode ad libitum sampling dari tiga induk tapir asia. Tingkah laku yang diamati yaitu saat beranak yang meliputi perilaku berbaring dan berdiri induk saat pengeluaran fetus, kontraksi beranak dan posisi beranak. Setelah itu, dilakukan juga pengamatan waktu awal induk mulai menjilati anak setelah beranak, bagian tubuh anak pertama dijilati,dan tingkah laku induk dalam menjilati anak. Hasil penelitian menunjukkan bahwa induk tapir cenderung dalam keadaan berbaring saat pengeluaran fetus dan sebagian besar induk pada posisi berbaring saat anak lahir. Kontraksi beranak pada ketiga induk tapir meningkat saat pengeluaran anak dan mengalami penurunan saat tahap pengeluaran plasenta atau setelah anak lahir. Waktu awal induk mulai menjilati anak setelah beranak adalah 39–106 detik setelah anak lahir. Induk segera menjilati anak dimulai dari bagian kepala. Ketiga induk tapir beranak secara normal dan menunjukkan sifat keindukan yang baik.

Judul: Karakteristik Carboxymethyl Chitosan Dengan Variasi Konsentrasi NaOH
Abstrak: Carboxymethyl chitosan is chitosan derivative product obtained from chemical modification. CMCh were made by alkalization process and carboxymethylation process. Factors that affect CMCh characteristics were excess sodium hydroxide in alkalization process, ratio between chitosan and monochloroacetic acid, and carboxymethylation temperature. The objectives of this research were to study the NaOH effect to CMCh characteristics, to learn process of making CMCh, to set the proper concentration of NaOH, and to analyze CMCh characteristics. CMCh yields were 110.72%-114.22%. CMCh pH value were 3.74-4.31. The optimum NaOH concentration to obtain the best CHCh was 10 M. Percentage of CMCh moisture content was 10.70%-11.42%. Ash content and nitrogen content of CMCh were 0.49%-0.50% and 4.52%-4.81%. CMCh viscousity was 8.25 cps. Percentage of CMCh solubility was 61.61%-91.50%. The different functional groups from chitosan which observed in CMCh were C=O group, CH group from alkene functional group, C−O group, and C−O−C group.
