The mining process can result in the mixing soil (post-coal mining soil) that tends to have low nutrient content, such as nitrogen, phosphorus, and also potassium which are crucial for plant growth. Additionally, the water flow in post-coal mining soil is often disturbed. The coal mining process can damage the soil structure and affect its ability to absorb water. The purpose of  study is to examine impact of palm boiler ash (PBA) and chicken manure fertilizer influence soil pH, bulk density, permeability, as well as the concentrations of total nitrogen, total phosphorus, total potassium. Research method use Completely Randomized Design with two factors: PBA (0 t ha^-1, 5 t ha^-1, 10 t ha^-1) and chicken manure (0 t ha^-1, 10 t ha^-1, 20 t ha^-1). The research findings show that applying PBA fertilizer and chicken manure impacts pH, bulk density, permeability, total nitrogen, total phosphorus, and total potassium from chicken manure.
