As a high school student who grew up in the region of Aceh, Putra showed a keen interest in the natural world. He studied the biology and
conservation of the Sumatran rhino: the smallest member of the most endangered rhinoceros in the family. Putra become an expert researcher and also a tracker, who led an expedition aiming to protects
rhinoceros in the field by pursuing and catching poachers in the Leuser Ecosystem. The area, which has an area of 6.4 million hectares of forest stretching from Aceh to
North Sumatra, is federally protected and is one of the largest remaining habitats supporting the Sumatran rhino. Putra realised that in addition to attempting to stop illegal hunting, his efforts would not be complete without discussing and confronting the threat posed by habitat destruction from illegal logging and palm oil plantations. Further studies show the importance of forests for the 4 million people living close to the Leuser Ecosystem. Forests also provide protection from flooding; in the Leuser ecosystem the frequency and severity has been increasing. Putra sees it as his job not only to protect the rhinos and their habitat, but also the people of the region. ==Illegal palm oil plantations==
