The importance of forests for the socio-economic life of a society is now felt to be increasing because cultural values in the form of human wisdom in managing nature are believed to be the best way to manage nature. This study aims to examine the material infrastructure aspect of the local wisdom of the Meratus Dayak community in Atiran Village. Data collection was done by field observations and interviews. Respondents were determined by purposive sampling method. Data processing is carried out by inductive qualitative analysis, which provides a general and comprehensive picture of the actual situation. Based on the results of research on local wisdom of the Meratus Dayak community in traditional forest management in Atiran Village, namely the cultivation pattern carried out by the Atiran Village community with a \"gilir balik\" cultivation pattern followed by rituals and customary rules and the Meratus Dayak community always uses land that is no longer productive again to be used as a forest gardenMasyarakat Desa Atiran sebagai suku Dayak Meratus sangat bergantung besar kepada hutan, rata-rata mata pencaharian mereka adalah sebagai petani yang memanfaatkan hutan untuk berladang, berkebun dan berburu. Pentingnya hutan bagi kehidupan sosial ekonomi suatu masyarakat kini dirasakan semakin meningkat karena nilai budaya berupa kearifan manusia dalam mengelola alam itulah yang diyakini merupakan cara yang paling baik dalam mengelola alam.

This study aims to analyze the level of land criticality and determine efforts to control the level of land criticality in the Tebing Siring Sub-Watershed of the Tabunio Watershed, Tanah Laut Regency. The methods used in the study are overlapping (overlayed) methods of land cover maps, slope maps and soil type maps with critical land determinant parameters in agricultural business cultivation areas including productivity, slopes, erosion and management. The results showed that land cover/use in oil palm plantations is included in the critical potential category, rubber plantations are in the rather critical to critical category, reeds are included in the critical category and open land is included in the very critical category.
