"Telah dilakukan penelitian mengenai endoparasit pada sampel feses Macaca fascicularis dan Macaca nemestrina di Kebun Binatang Taman Sari Bandung, pada bulan Desember 2010--Mei 2011. Penelitian bersifat non-eksperimental dan bertujuan untuk mengamati endoparasit pada sampel feses Macaca fascicularis dan Macaca nemestrina ditinjau dari kehadiran endoparasit. Sebanyak 61 sampel feses telah diperiksa dengan 31 sampel feses Macaca fascicularis dan 30 sampel feses Macaca nemestrina. Sampel feses dianalisis menggunakan metode Pengapungan Sentrifugasi. Berdasarkan hasil pemeriksaan dari 31 sampel feses Macaca fascicularis, Ascaris lumbricoides merupakan endoparasit yang ditemukan dengan frekuensi kehadiran tertinggi yaitu 77,41%. Berdasarkan hasil pemeriksaan dari 30 sampel feses Macaca nemestrina, Trichuris trichiura merupakan endoparasit yang ditemukan dengan frekuensi kehadiran tertinggi.

This research was conducted to identify endoparasites on fecal samples of Macaca fascicularis and Macaca nemestrina at Taman Sari Zoo, on Bandung, since December 2010 until May 2011. The aim of this non experimental research was to observe the presence of endoparasite from fecal sample of Macaca fascicularis and Macaca nemestrina. There were 61 fecal samples observed in this research consist of 31 fecal samples collected from Macaca fascicularis and 30 fecal samples collected from Macaca nemestrina. Fecal samples were analyzed by flotation centrifuge methods. The result showed that 31 fecal samples from Macaca fascicularis had the highest frequency of Ascaris lumbricoide (77,41%), meanwhile 30 fecal samples from Macaca nemestrina showed that Trichuris trichiura found to be the highest frequency (76,6%)."

"ABSTRAKPenelitian tentang preferensi pohon tidur joja (Presbytispotenziani) di Siberut Utara, Kepulauan Mentawai, telah dilakukan pada bulan Februari--Agustus 2010. Penelitian bertujuan untuk mengetahui preferensi dan karakteristik pohon tidur joja, serta memetakan pohon tidur tersebut di kawasan kajian. Penelitian dilakukan terhadap satu kelompok joja yang telah terhabituasi penuh. Metode yang digunakan adalah spotobservation. Hasil yang didapat menunjukkan tumbuhan yang dipakai sebagai pohon tidur sebanyak 13 spesies dengan kelimpahan tertinggi pada spesies petpetnuit atau nangka (Artocarpusinteger) sebesar 25,71%. Karakter pohon tidur yang digunakan di antaranya memiliki tinggi 26--30 m, diameter 41--70 cm, lebar tajuk 11--15 m, dan tidak dililit oleh liana. Joja cenderung memilih pohon tidur tertinggi dan terbesar, serta pohon yang dapat memberikan kenyamanan dan keamanan pada saat tidur. Distribusi pohon tidur tersebar di seluruh daerah jelajah (homerange) kelompok joja yang diamati, dengan pola mengelompok. Distribusi pohon tidur dipengaruhi oleh ketersediaan sumber pakan di kawasan kajian.

ABSTRACTResearch on the sleeping tree preference of joja (Presbytispotenziani) at Northern Siberut, Mentawai Island, was conducted in February to August 2010. This study aims to determine the preferences and characteristics of joja sleeping trees, and to map sleeping trees of joja in the study area. The data were collected from a group of well-habituated joja. Spot observation method used for characterizing the sleeping trees. The results found that the trees used as sleeping trees were found to be 13 species, and they were used repeatedly with highest frequency in petpetnuit or nangka (Artocarpusinteger) amounted to 25,71%. The height of the sleeping trees was within the range 26--30 m, the DBH was 41--70 cm, the diameter of the crown was 11--15 m, and the average 0,41 liana attached on the sleeping trees. Joja usually selected the tallest trees and the trees with the greates DBH. Joja tends to choose the sleeping trees that support the comfort while sleeping and avoid predation risk. The distribution of sleeping trees are clustered all over home range. The distribution of food source within the study area influencing the choice of joja sleeping trees."

"Pengamatan terhadap perilaku reproduksi dan profil Pregnanediol-3-Glucuronide (PdG) Kukang Sumatra (Nycticebus coucang) Betina di Penangkaran, telah dilakukan selama tiga bulan di Pusat Studi Satwa Primata, LPPM-IPB dan Laboratorium Mikrobiologi dan Imunologi Pusat Studi Satwa Primata Bogor, Institut Pertanian Bogor. Penelitian bertujuan untuk mengetahui perilaku harian N. coucang yang difokuskan pada pengamatan perilaku reproduksi dan pengukuran kadar hormon metabolit Pregnanediol-3-Glucuronide (PdG) pada feses N. coucang. Dari pengamatan, kami mendapati perilaku reproduksi berupa jantan mengendus (sniffing) dan menjilat (licking) bagian genital betina. Hingga waktu pengamatan berakhir, tidak teramati terjadinya kopulasi. Kadar hormon PdG pada kandang no. 2 berkisar dari 20,85±5569,11pg/ml sampai 19995,81±11061,7 pg/ml, sedangkan kadar hormon PdG pada kandang no. 5 berkisar dari 504,97±936,67 pg/ml sampai 18168,68±12556,1 pg/ml.

Observation of reproductive behavior and profile of Pregnanediol-3-Glucuronide (PdG) in captive housed female sumatran slow loris (Nycticebus coucang) has been conducted for three months at Pusat Studi Satwa Primata, LPPM-IPB and Laboratorium Mikrobiologi dan Imunologi Pusat Studi Satwa Primata Bogor, Institut Pertanian Bogor. The study aims to determine the daily behavior of N. coucang focusing on the observation of the reproductive behavior and measurement on the levels of the hormone metabolites Pregnanediol-3-glucuronide (PdG) in feces of N. coucang.

From the observation, reproductive behavior such as sniffing and licking of female genital parts by male N. coucang were observed. Until the end of the observation time, copulation is not observed. PdG hormone levels in the enclosure no. 2 is range from 20.85 ± 5569,11pg/ml to 19995.81 ± 11061.7 pg/ml, while PdG hormone levels in the enclosure no. 5 is range from 504.97 ± 936.67 pg/ml to 18168.68 ± 12556.1 pg/ml."
