The Study of Soil Permeability Test for Landfill of Slag and FABA in The Area of Location 2 LB3 in The Regency of Central Halmahera

One of the feasibility methods for landfill nickel slag and FABA is soil permeability test. Data interpolation results from all areas consisted 7 sampling points in location 2 LB3. The testing Borehole on showed domination sand-sized material with 74.40 – 86.10% (first meter) 82.04 91.77% (second compared to clay gravel materials. Interpolation class area Location LB3 ranged "slightly fast" "fast" a layer depth 0-2 meters. Furthermore, classification based Verruijt that overall observed were Medium Permeability class. This result was determined by presence which more dominantly concentrated than clay-sized material.
