This research aims to predict soil erosion/deposition in Ciesek subwatershed, Upper Ciliwung watershed using natural fallout radionuclides of <sup>137</sup>Cs and <sup>210</sup>Pb excess. Soil samples were taken using soil core along four transects of different land use types.&nbsp; Soil samples were analyzed using Multi Channel Analyzer (MCA) to obtain inventory value of the radioisotopes. The research shows different distribution pattern of soil erosion/deposition of <sup>137</sup>Cs and <sup>210</sup>Pb excess isotopes. Application of <sup>137</sup>Cs isotope shows soil erosion process under home mix garden and dryland farm, but soil deposition process occurs on bareland. In the contrary, <sup>210</sup>Pb excess indicates soil erosion on bare land while soil deposition is under home mix garden and dryland farm. Application of <sup>210</sup>Pb excess is more reliable than <sup>137</sup>Cs in predicting soil erosion. </em></p&gt;}, number={3}, journal={Jurnal Pengelolaan Sumberdaya Alam dan Lingkungan (Journal of Natural Resources and Environmental Management)}, author={Murtilaksono, Kukuh and CitraresminiAnia and YusufSri Malahayati and BachtiarTaufik and LawaswatiDwi Mei}, year={2020}, month={Oct.}, pages={501-510} }
