Sumatran elephant (Elephas maximus sumatranus) is a social animal living in groups. A group of elephant is called herd consists of male, female, allomother and calf. Non-parenting females are called allomother with the role of maintaining calves from other females. In daily activity, allomother may also display a typical infant handling which is valuable for studying interaction between them. This study will describe the daily activity of elephant allomother in Tangkahan Conservation Response Unit (CRU) Area, Langkat, North Sumatera. Methodology used was focal animal sampling with continuous sampling of data record. Object in this study were two allomothers, namely Ardana and Sari with three calves, namely Christopher, Albertina and Eropa. Daily activities of allomothers were recorded as Defecating (DF), Urinating (UR), Mudding (MU), Resting (RE), Mating (MT), Salting (ST), Feeding (FE), Parenting (PR), Drinking (DR) and Walking (WK). We recorded 19,569 sample points from allomother daily activities with Ardana having 10,838 points and Sari having 8,821 points. The longest duration of activity recorded were: Parenting (PR) with 5,807.13 min, Walking (WK) with 5,695.50 min and Feeding (FE) with 3,842.71 min. The shortest duration recorded was Mating (MT) with only 18.96 min while remaining activities lasting between 346.25 to 614.63 min. Duration of daily activities is directly proportional to the percentage of frequency performed by allomothers.
