Abstract: Unmul Samarinda Botanical Gardens is a forest that grows naturally, along with population growth and the development of the city of Samarinda, the Unmul Samarinda Botanical Gardens (KRUS) is in the middle of the city. The Unmul Samarinda Botanical Garden is expected to function as an educational forest that supports science. Since 2001, Mulawarman University together with the Samarinda City government have developed a nature recreation/ecotourism function. In KRUS Forest, apart from high-level vegetation, shrubs, low-level vegetation and mosses are also found. Wild animals, birds, reptiles, amphibians and other aquatic animals also still exist in this area. This study aims to determine the diversity, evenness and dominance of the order anura. The method used in collecting data on the diversity of the Anura order is the Visual Encounter Survey (VES). For sample identification and data processing, it is carried out at the Laboratory of Animal Ecology and Systematics, Faculty of Mathematics and Natural Sciences, Mulawaman University, Samarinda. Research results show that the composition of the order Anura in the Unmul Samarinda Botanical Gardens (KRUS) consists of 18 species, 6 families and 108 individuals. Species with the highest number of individuals were Limnonectes paramacrodon and Pulchranapicturata. The index of species diversity of the order Anura is moderate with a value of 2.26, the index of evenness is relatively even with a value of 0.79 and the dominance index indicates that there is no dominant species with a value of 0.17. There are several factors that pose a threat to the species of the Anura order in the Educational forest of the Unmul Samarinda Botanical Gardens (KRUS), such as tourism activities and coal mining which makes the forest fragmented.
