Local Wisdom of the Dayak Kenyah Customary Community in the Management of Tana Ulen in Kayan National Park, Mentarang, North Kalimantan

In accordance with the nobility of the local wisdom of the Dayak Kenyah indigenous people in Long Alango Village, Bahau Hulu District, Malinau District, the indigenous peoples have known the concept of conservation for centuries or are more familiar with the term Tana 'Ulen. Tana ?Ulen in the language of the Dayak Kenyah Indigenous people means an area that is banned or has been imposed by someone's rights so that it is no longer free for other people to enter. Physically, Tana ?Ulen is a primary forest area along certain watersheds that are rich in natural resources of high economic value to the local community, and located not too far from the village. This study aims to describe and analyze comprehensively and in detail the local wisdom practices of the Dayak Kenyah indigenous people in the management of Tana 'Ulen, the impact of the local wisdom practices of Dayak Kenyah indigenous people in the management of Tanah Ulen in Kayan Mentarang National Park against deforestation, and models of local wisdom practices which can prevent deforestation. Data that has been collected through field observations and in-depth interviews (in-depth interviews), and documentation studies, then tested the validity and reliability. After that, it was analyzed using the data analysis technique of the Interactive Analysis Model (Mile, Huberman, and Saldana), namely the analytical method used for analysis of qualitative data obtained in the field and continuous reciprocity during the research. In its implementation, the method used is by integrating interactively and circularly between data collection, data condensation, data display, and then drawing conclusions and verification (drawing / verification). The study has the following conclusions, namely 1) The impact of the local wisdom practices of Dayak Kenyah indigenous people in the management of Tana Ulen in Kayan Mentarang National Park on forest destruction can be identified as follows: (a) Community wisdom about forest management, namely the distribution of forest utilization zones. (b) Tana Ulen can function as a 'granary' village so that the potential of forests in the KNP area can provide a sense of security and guarantee for the survival of the community both economically and socially to support the existence of the Dayak Kenyah indigenous people.2) Factors that support the practice of local wisdom of the Dayak Kenyah indigenous people in the management of Tana Ulen in Kayan Mentarang National Park are the active participation of indigenous peoples in applying local wisdom in their daily lives and this also has the support of indigenous peoples' representative forums and customary institutions. The inhibiting factors related to the Forestry Service have not been optimal in establishing communication and involving indigenous people in the management of Tana Ulen in Kayan Mentarang National Park.3) The model of local wisdom practices that can prevent forest destruction departs from the awareness of the community to respect their ancestors and continue to obey and not ignore ancestral advice that forests are part of their lives so they must be preserved. The real impacts that can be felt include the preservation of forests that are still maintained, the preservation of flora and fauna, maintaining the balance of ecosystems around the forest preventing deforestation, reducing potential disasters such as erosion and flooding, the beauty of natural forest charms, cleanliness of water sources, adequate water availability and avoidance from the problem of water difficulties so that the community's need for water can be fulfilled.
