The objective of the study was to identify the parameters of soil damage so that the level of damage that occurs was known as a decision-making material with an appropriate approach to the problem so that the productivity of the land does not decrease even increased as a cultivation area that has a function for biomass production. The first step is to determine the potential for indicative soil damage by overlaying with the GIS-based digital map i.e. soil type map slope rainfall land cover then with the spatial and regional plan map. The results obtained 4 classes of potential indicative soil damage namely low 1 medium 2 high 3 and very high 4. Observations were made at 3 and 4. Number of field observation points and soil samples respectively 4 and 2. Field verification found that an effective soil depth solum thickness at 3 was 26880590 cm 25-40 slopes were used for agriculture whereas 4 was 20 cm and 26880560 only secondary forest. The results of the evaluation found that 5 parameters exceeding the threshold namely solum thickness s surface of rocks b permeability p soil acidity a and electrical conductivity e. Based on the relative frequency score the soil damage status is slightly damaged at 3 by limiting factor a or D.I-a while at 4 moderately damaged by limiting factor s b p and e or D.II-s b p e. Improvement actions in D.I-a are soil treatment organic fertilizing compost and liming whereas in D.II-s b p e is difficult to repair due to natural factors.
