The Eucalyptus plant (Melaleuca cajuputi) is useful as a producer of essential oils and is able to live in extreme areas such as post-mining land. PT Bukit Asam Tbk (PTBA) has produced this plant in large quantities to meet the needs of seeds to be planted in the reclamation area of a former mine by providing bocation fertilizer.
