Abstract
Open-pit coal mining causes landscape changes and decreasesthe soil’s physical, chemical, and biological quality. These conditions cause the carrying capacity for agricultural cultivation on ex-mining land to be low. Efforts can be made to improve the quality of ex-coal mine soil by providingorganic materials. The type of organic material withthe potential and sufficient amount to reclaim ex-coal mine land and support plant growth is known as Palm Oil Empty Bunch Compost (TKKS). This research used a randomized group design (RGD) based on slope direction. This study consisted of 6 treatments, namely: k0 = no compost (control), k1 = 0.75 kg/plant, k2 = 1.5 kg/plant, k3 = 2.25 kg/plant, k4 = 3 kg/plant, and k5 = 3.75 kg/plant. The observed variables were pH,P-available, C-organic, plant height, and diameter.The research data were analyzed usingvariance to see the effect of the average treatment followed by Duncan's Multiple Range Test at α = 5%The result of this study showed that the compost was able to increase soil pH and C-organic, reduce Al-dd, and increase plant height and diameter, but did not increase P-available. The best dose of TKKS compost to improve soil chemical properties is 3 kg/plant
