Abstract:
The preservation of biodiversity is a complex issue. Biodiversity shrinkage has become an international and national policy issue. The international community has given authority to the International Union for Conservation of Nature and Natural Resources (IUCN) to develop thinking on the basis of conservation efforts. The organization shows how biodiversity is fundamental to addressing some of the world's biggest challenges in tackling climate change, achieving sustainable energy, improving human well-being and building a green economy. While biodiversity conservation efforts in Indonesia are handled directly by the central government through its technical implementation unit, BKSDA. The task of BKSDA is to carry out its function in order to achieve maintained natural conditions, inhibit extinction, realize environmental balance, and improve tourism in the archipelago, and Indonesia has many diverse flora and fauna, and of course a good legacy for the next generation. Orangutans are native to Indonesia, where Indonesia has 3 types of orangutans, namely Sumatran orangutans, Tapanuli orangutans and Bornean orangutans, the orangutan population is always decreasing, making orangutans in critical endangered status. With the above background, the Author discusses how the IUCN’s role in orangutan conservation in Indonesia, IUCN refers to the United Nations on Convention of Biological Diversity (UNCBD). Indonesia ratified the convention into Law No. 5 of 1994 concerning the United Nations Convention on Biodiversity. Article 5 of the KKH states that, each party must cooperate with other parties through international organizations competent for the conservation and sustainable utilization of biodiversity where possible and enforceable.
