- Soil organic matter (OM) is very important in its function, but information about the chemical composition, chemical structure and the changes caused by anthropogenic factors in the processing system is still in the research. The research objective is to examine the characteristics of organic materials and their derivatives, and their functions in various land use changes. Soil samples were taken at a depth of 0-20 cm in the Bromo mountainous lands under changes in land use of: coffee gardens (CT); apple orchard (AT); vegetable garden (VT) and secondary forest (SF). Soil samples were analyzed for C-org content, humic acid, pH, CEC, total of P, aggregate stability, and redox potential. The characteristics of humic acid were analyzed using Fourier Transform Infrared (FTIR), UV-Vis fluorescence spectroscopy and elemental analysis (CHNS). The FTIR spectrum of HAs is similar for all land uses. The results showed that humic characters varied between all samples tested. There is a positive correlation between changes in intensive land use to secondary forests with soil physical chemical characteristics, C-organic content and humic character.
