Landfill in Bantargebang integrated solid waste treatment facility received 85% of the municipal solid waste of Jakarta Province in 2021. Since it is almost filled, the government operated a landfill mining (LM). This research aimed to characterize and evaluate the humate soil potential from mined material (MM) for agriculture. The weight, volume, and density of MM were measured on randomly selected collection vehicles in the LM location for eight consecutive days on March 2-15, 2022. Composition analysis was conducted by sieving and classifying samples into fine (FF), medium (MF), and coarse fractions (CF) of < 10 mm, 10-30 mm, and > 30 mm, respectively. MM had a weight, volume, and density of 81.43±13,03 tons/day, 147.84±33.31 m3/day, and 0.56±0.06 tons/m3, respectively. FF had soil-like material of 13.96±1.12%, while MF was 18.74±1.10%. Both fractions contained moisture, volatile solids, ash, carbon, nitrogen, and C/N ratio of 56.92-63.47%, 69.17-74.81%, 25.19-30.83%, 52.87- 55.67%, 1.89-2.10%, and 25.17-29.46, respectively. These characteristics met compost quality standards, except for high moisture content, which made it suitable for agriculture after moisture reduction. Meanwhile, plastics and wood-dominated CF were suitable for non-agriculture. A toxicological test is recommended to ensure the humate soil's safe use.
