Abstract

Tailings are the final result of mining industry activities. Tailings are in the form of sludge waste produced from mining gold, copper, silver and other minerals. Tailings can potentially damage the environment and be dangerous to human life and other creatures. One effort to restore land from tailings is bioremediation technology. Biochar is a soil amendment material that can be used for environmental remediation. Utilizing meranti wood waste as biochar can reduce waste and increase economic value. Mahogany is a type of plant that is known to have potential as a phytoremediation plant. The aim of this research is to determine the effectiveness of meranti wood biochar to improve the growth of mahogany planted in gold tailings media. This research was carried out for four months in a greenhouse. The research was designed using a Completely Randomized Design (CRD) with the treatment of gold tailings and meranti-based biochar in the growing media used. There were 12 treatments with four repetitions. The treatment given is (1) 0% tailings+0% Biochar; (2) 25% tailings+0% biochar; (3) 50% tailings +0% biochar; (4) 0% tailings+5% biochar; (5) 25% tailings + 5% biochar; (6) 50% tailings +5% biochar; (7) 0% tailings + 10% biochar; (8) 25% tailings + 10% biochar; (9) 50% tailings + 10% biochar; (10) 0% tailings + 15% biochar; (11) 25% tailings + 15% biochar; (12) 50% tailings + 15% biochar. The parameters observed were height increase, diameter increase, leaf area and root length. The research results showed that the application of biochar was able to improve the growth of mahogany planted in gold tailings media. Providing 10 and 15% biochar on media with gold tailings even resulted in better mahogany growth compared to those grown on media without tailings. This shows that meranti-based biochar has the ability to become a soil amendment for land contaminated with gold tailings.
