Mount Sinabung eruption caused the soil covered by volcanic ash with various thickness. Changes in soil conditions will affect population and diversities in the soil. The research aims to identify soil macro-fauna on andisol in Karo County with various thickness of volcanic ash of Mount Sinabung with different vegetation after 5 years of eruption. The Plots were placed onto eight locations, I = processed land (0 cm) grass vegetation, II = uncovered by ash land (0 cm) coffee vegetation, III = covered by thin layer of ash land (≤2 cm) grass vegetation, IV = covered by thin layer of ash land (≤2 cm) coffee vegetation, V = covered by medium layer of ash land (2-5 cm) grass vegetation, VI = covered by medium layer of ash land (2-5 cm) coffee vegetation, VII = exposed by thick ash land (≥5 cm) grass vegetation, VIII = exposed by thick ash land (≥5 cm) coffee vegetation. Sampling was done by method Pitfall Trap, Square Monolith, and Hand Sorting. The result shows that the change of soil will affect soil macro-fauna - based on macro-fauna identification results, found 3 phylum(s), 7 class(es), 12 ordo(s), 18 family(ies), and 20 species.
