Forest is a natural environment that could not be evaded from continuous interactions with humans who lived around. The interactions is one way of human to use forest potention. Human activity to use forest is very often result in forest and enviromental degradation. One solution that could keep forest sustainability is a sustainable forestry management which put forward the conservation aspects. In this forest management, soil as a vital resources for plants growth needs to have sufficient attention because soil is one of the most important habitat besides climate and topography factors. A research to evaluate the soil physical and chemical changes due to deforestation activity with RIL and CNV technique was carried out on CIFOR research plots. Upon the research, soil samples were taken from RIL, CNV, and Control plot. The soil samples were analyzed in Soil Physical Laboratory and Soil Chemical Laboratory in Soil Science and Resources Department, IPB. The data which is examined from physical and chemical analysis then statistically analyzed with Test of Between Subjects Effects, and continued by Duncan Test with p < 0,05 to view the relationship between RIL, CNV, and Control plot conditions. Results from physical analysis showed that bulk density on CNV plot is higher than that on RIL and Control plot. Meanwhile, the values of porosity, available water, and permeability on CNV are less than those on RIL and Control plot. Results from chemical analysis showed that C-Organic, Total-N, available P, K, and Cation Exchange Capacity (CEC) values on CNV plot are less than those on RIL and Control values. Statistics analysis showed that the values of bulk density, porosity, available water, C-Organic, Total-N, available P, K, and KTK on CNV, RIL, and Control plot are not significantly different. Meanwhile, the values of permeability on CNV plot is significantly different from RIL and Control plot. Examined soil physical changes are increasing of bulk density, decreasing of porosity, available water, and permeability. Examined soil chemical changes are decreasing of C-Organic content, decreasing of Total-N, decreasing of available P, decreasing of K, and decreasing of Cation Exchange Capacity (CEC). Physical and chemical changes on RIL plot are less than CNV plot, which means that RIL technique is better than CNV technique.
