Post-mining land has potential damage after mining activities ends, excavating the soil and returning it to the ex-mining pit causes the soil bearing capacity to be low and even damaged so that reclamation with adaptive plants such as melaleuca cajuputi (eucalyptus) is needed. The purpose of this study was to determine the effectiveness of the growth of melaleuca cajuputi plants in post-mining locations. The research method used is by making field benchmarks to measure and analyze plant growth rates, plant health percentages, plant height and diameter. The results of the analysis of the percentage of plant growth in the three sampling locations showed that the percentage of plant growth was above 90%, so it could be said that the plant growth was in excellent condition. The health level of plants at the East Backfilling Pit 3 and West Backfilling Pit 3 locations showed 100% healthy results for the number of living plants while in the West Backfilling Pit 1 location there were still plants that languished due to lack of plant maintenance. The success of reclamation can be achieved if the plants grow well and are healthy, the percentage of plant growth desired and the number of plants per hectare are achieved. The conclusion from  this research that the planting of melaleuca cajuputi is very effective as a reclamation plant of PT. Bukit Asam, Tbk. because this plant can grow well, adaptive in critical land conditions and provides high economic value and also give benefits to the community.
