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

Abstract

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