At the end of 2020, Talang Gulo Landfill Site 1 in Jambi City was officially closed due to overcapacity. Municipal solid waste disposal has shifted to the Talang Gulo site 2 with a life expectancy of ± 90 years based on the design plan. However, this is difficult to realize because segregation and composting are not optimal, so more than 90% of the waste transported to the final processing site (TPA) is in a landfill. Thus, landfill mining was executed to utilize excavated landfill waste as a material and energy. It was carried out at depths of 3, 5, and 7 meters with an estimated sample age of > 9 years. The mixed landfill samples contained 55.6–66.2% moisture content, 50.3–80.6% volatile content, 19.4–49.7% ash content, 2.6–4.2% fixed carbon, and 3.5–5.7 MJ/kg calorific value. Furthermore, the landfill waste was dried using the biodrying method, combining fresh and landfill waste in the pile composition. The ratio of landfill waste to the addition of fresh waste is 1:0 (control pile), 1:1, 1:2, 1:3, and 1:4. The drying method reduced moisture content of 9–29.1% with a lower calorific value of 5–6.8 MJ/kg. Based on statistical analysis, it is known that waste ratio has a significant effect on moisture content. Based on the weighting results, the optimum mixture ratio is 1:1 (pile 2).
