Abstract

Post-mining due to mining activities will produce heavy metals in the form of acidic water and accumulate in the land. The poor quality of the land used by tin mining causes damage to the land ecosystem so that the land cannot be regrown by vegetation and the Pb (Lead) content in tin tailings is 6.29 ppm. The aim of this research is land restoration, namely carrying out revegetation using sunflower plants to absorb the heavy metal Pb with the concept of edutourism. The method used is a simulation of planting sunflowers on an ex-mining area of 1 Ha, with a planting distance of 1 m, the number of sunflower plants is 8540. The research results show that with the sunflower garden concept by planting 8540 sunflowers, the Pb level that can be absorbed by the plants is 2.8310 kg.

Abstract

The environmental damage resulting from mining not only eliminates soil fertility but changes the landscape of the existing ecosystem and produces waste such as tailings and kaolin and understory. The results of tin and kaolin tailings mining have not been utilized optimally. This research aims to analyze the effect of using tin tailings sand and kaolin on bricks which produces compressive strength and water absorption in accordance with standards. The method used is to take tin and kaolin tailings mixed with clay with a predetermined composition and tested in the laboratory. Based on the test results, the compressive strength value obtained meets the standards, namely the percentage of 15% tin tailings sand and 10% kaolin, the compressive strength value is 5,150 Mpa. The water absorption value using percentages of 5%, 10% and 15% tin tailings sand and 10% kaolin has met the specified standards.
