Lutung perak (Trachypithecus cristatus) tergolong ke dalam status vulnerable berdasarkan IUCN yang menyebabkan salah satu lembaga konservasi ex-situ yakni Taman Margasatwa Ragunan berperan dalam melestarikannya. Perubahan kondisi lingkungan yang signifikan dapat memunculkan gejala stres sehingga mereka harus menyesuaikan diri di lingkungan yang baru. Dalam proses tersebut, penting untuk melihat perilaku yang dapat terdampak salah satunya perilaku pengasuhan anak (parental care). Terdapat tipe pengasuhan berupa alloparental care pada lutung perak. Penelitian ini bertujuan untuk menganalisis perilaku pengasuhan anak pada lutung perak di luar habitat aslinya yang berada di Pusat Primata Schmutzer, Taman Margasatwa Ragunan. Terdapat 7 individu yang menjadi subjek penelitian, yaitu dua jantan dewasa, tiga betina dewasa, satu betina remaja dan satu anak lutung perak. Metode dalam penelitian ini berupa scan sampling dan ad-libitum sampling. Berdasarkan hasil, terdapat 9 perilaku dengan nilai rata-rata tertinggi berupa feeding sebesar 15,6 kali saat hari libur satwa dan breastfeeding sebesar 14,3 kali saat akhir pekan. Secara keseluruhan pengasuhan anak lutung perak di Taman Margasatwa Ragunan tergolong baik karena tidak memunculkan perilaku agonistik.

The silver langur (Trachypithecus cristatus) is classified as vulnerable according to the IUCN, which causes one of the ex-situ conservation institutions, Ragunan Wildlife Park, to play a role in preserving it. Significant changes in environmental conditions can lead to symptoms of stress so that they must adjust to the new environment. In this process, it is important to look at behaviors that can be affected, one of which is parental care behavior. There is a type of alloparental care in silver langurs. This study aims to analyze parenting behavior in silver langurs outside their natural habitat at the Schmutzer Primate Center, Ragunan Zoo. There were 7 individuals that became the subject of the study, namely two adult males, three adult females, one juvenile female and one infant silver langur. The methods in this study were scan sampling and ad-libitum sampling. Based on the results, there were 9 behaviors with the highest average value of feeding 15,6 times during animal holidays and breastfeeding 14,3 times on weekends. Overall, the parenting of silver langur children in Ragunan Wildlife Park is classified as good because it does not cause agonistic behavior.
