Abstract

The purpose of this study was to determine the effect of municipal solid waste compost using MOL snail mas and Trichoderma sp. against the land of ex coal mining and knowing the dosage of municipal waste compost in increasing the nutrients in the ex-coal mine soil. This research was conducted for 3 months from April 2018 to June 2018. The research location was at the Laboratory of Soil Science, Faculty of Agriculture, Mulawarman University. This study used a completely randomized design method (CRD) with 4 treatments and 3 replications. The treatments are P0 (control without treatment), P1 (100 gr Polybag -1), P2 (150 gr Polybag -1), P3 (200 gr Polybag -1). Soil data analysis was carried out descriptively by comparing the results of the initial soil analysis with the final soil analysis after incubation. Comparison of initial soil analysis data and final soil analysis is discussed based on the criteria for assessing soil chemical properties of Bogor Soil Research Institute 2005
