This research observed the effects of olfactory enrichments on the adaptive behavior of captive Sumatran tigers at Ragunan Zoological Park. Olfactory enrichment was given in form of fresh prey feces obtained from Ragunan herbivore enclosures. Observation ran for seven weeks with three weeks of baseline observation, two weeks of enrichment, and two weeks of post-enrichment observation. The data collection process was entirely done through digital ethogram as an effort to optimize the research. Core data consisted of behavior type, duration, and frequency. Additional data included spatial mapping and interactions between tigers and objects. Efficiency of data collection process was successfully improved through automatic recording of time, behavior, tiger position in the enclosure, and interaction targets. Statistical analysis of time budget revealed significant differences between the prevalence of adaptive behavior pre-enrichment (9.8 ± 1.92%) and during enrichment (1.1 ± 0.29%). Lowered levels of adaptive behavior is followed by an increase in positive exploratory behavior. Positive exploratory behavior consists of behaviors from Interaction and Locomotion categories. The increase in locomotion is observed even after enrichment ceased to be given. Changes in behavior resulted from fluctuation of stimulus that the tigers were exposed to within the enclosure. It can be concluded that digital ethogram increases the efficiency of data recording in direct observation and that olfactory enrichment influences the prevalence of Sumatran tiger adaptive behavior at Ragunan Zoological Park.
