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

PT XYZ had a method called the on book method to determine the amount of coal tonnage in the ROM stockpile.. This method used the initial stock from the survey calculation resut at the beginning of each month, the incoming coal to the stockpile used truck count method, and the outgoing coal from stockpile used weighbridge calculation. PT XYZ used the survey calculation results at the beginning of the next month rather than on book method result to determine the difference. The Coal tonnages based on survey result data on April 2 was 34.225,454 tons. Whereas, for the on-book calculation, the stock at March 2 was 38.409,083 tons, the coal in 2 March - 2 April was 71.154 tons, and the coal out of 2 March - 2 April was 67.994,52 tons, so the final stock obtained was 41.568,56 tons. The difference from those two methods comparison was 7.343,11 tons. This research discover the factors causing the differences between two methods i.e. incompatible vessel capacity on the truck counts tonnage calculation, disorganized stockpile patterns, declining ROM stockpile base conditions, spilled material, total station tools and weighbridges which had not been calibrated yet.

Abstract

Mine Acid Water is one of the impacts of the mining industry that must be handled seriously because it can cause environmental quality degradation. The factor for the formation of AAT is due to the presence of sulfide minerals in the rock. It is necessary to prevent the formation of AAT by identifying rocks that are Potential Acid Forming (PAF) and Non Acid Forming (NAF). Identification of an AAT is carried out by static test. The research method uses quantitative data in the form of rock sampling with full coring drilling and conducting static tests in the laboratory. The results of this study were M01 samples (white sandstone) with ANC values of 1.7 KgH2SO4 /ton, NAG pH 6.63, Total Sulfur <0.01%, pH of paste 7.22 and NAPP -1.4 KgH2SO4 /ton. The sample was M02 (sand) with ANC value of 1 KgH2SO4 /ton, NAG pH 6.63, Total Sulfur <0.01%, pH of paste 7.37 and NAPP -0.7 KgH2SO4 /ton. The sample was M03 (black sandstone) with ANC value of 1.4 KgH2SO4 /ton, NAG pH 4.41, Total Sulfur 0.06%, pasta pH 6.89 and NAPP 0.4 KgH2SO4 /ton. The geochemical identification of rocks at PT Menara Cipta Mulia has 2 samples, namely M01 (white sandstone) and M02 (sand) samples that are Non Acid Forming (NAF) and 1 sample, namely M03 (black sandstone) samples that are Potential Acid Forming (PAF).
