Abstract

– Gaming technology has been growing these years rapidly. The game engines have the capability of creating a very realistic virtual environment model. This technology can also be used for mining purposes. In this research, the game engine is specifically used to develop a mine self-escape simulation game for training purposes. The game engine which is used to develop the simulation game is Unreal Engine 3. The main advantage of using such a simulation game as a training tool is because it allows the trainee to experience a dangerous situation while not being put in danger. This kind of training is considered better than conventional briefing, normally conducted by showing a video or pamphlet. Studies have shown that people retain more information when they are involved interactively in the learning process. In this research, a computer simulation game as a training tool for underground coal mine self-escaped has been successfully created using fire scenarios. The player/trainee should follow some procedures to get to the safety zone

Abstract

The physical and chemical environmental impact in a mining area is inevitable, particularly for open pit mining areas. The impact could affect soil and water quality where mining activities, such as land clearing, blasting and hauling, occur. Thus, environmental monitoring in mining areas should be taken to measure the impact of mining activity for reclamation purposes. The objective of this research focuses on the measure of environmental impact on soil quality in terms of the nutrient content in an abandoned mine area at Jantang village, Lhoong, Aceh Besar. The research was conducted by collecting 15 soil samples, followed by laboratory analysis using atomic absorption spectrophotometry to investigate sampled 'soil's nutrients which are pH, Carbon (C-organic), Nitrogen (N-total), Phosphor (P-availability), and Ferro substance (Fe-concentration). In addition, to estimate the soil properties at locations outside the sampling area, a spatial interpolation method called inverse distance weight with an optimum power was used. The result shows that the soil is acidic, with low C-organic in the range of 0.02%–1.84%, N-total 0.02%–0.16%, and P-availability 0.55%–3.75%. In contrast, the Fe-concentration is very high, at 3000–3400 ppm.

Abstract

Ketersediaan air tanah yang memadai menjadi krusial seiring dengan pertumbuhan populasi manusia. Artikel ini mengungkapkan studi tentang keberadaan sumber air tanah alternatif di Kawasan Lam Cot, Aceh Besar. Metode geolistrik resistivitas digunakan untuk mengidentifikasi kedalaman lapisan akuifer dan potensi sumber air tanah dalam. Pengukuran dilakukan pada satu titik pengukuran dengan penggunaan resistivitimeter SuperSting R8/IP. Hasil pengukuran resistivitas semu menunjukkan variasi nilai antara 0,5 hingga 193,2 Ωm dengan kedalaman berkisar 0 hingga 140 meter. Identifikasi keadaan litologi di bawah permukaan menunjukkan adanya tanah lempung, lanau, batuan kerikil, dan batu pasir dengan nilai resistivitas yang berbeda pada kedalaman tertentu. Meskipun akuifer tidak ditemukan dalam jangkauan pengukuran, penelitian ini memberikan pemahaman yang mendalam tentang kondisi hidrogeologi kawasan tersebut. Diperlukan studi lanjutan dengan pengukuran yang lebih luas untuk mendapatkan informasi yang lebih komprehensif tentang sumber air tanah di Kawasan Lam Cot.

Abstract

Illegal gold mining carried out using amalgamation techniques produce mercury waste which can then damage the environment and damage the health of residents. The negative impact due to the use of mercury is dead fish, contaminated river water, water quality below environmental standard quality and spreading in the food chain. This has caused environmental damage, one of which is in terms of land and water. This condition is the basis for conducting deeper research on environmental damage by mercury waste, especially in terms of soil and water. The sampling method used is the Geochemical Method and Geoelectric Method. Geoelectric samples were taken using the superstring R8 tool. Geochemical samples used were soil and water samples which were subsequently tested by the Atomic Absorption Spectrophotometry (AAS) and X-ray Fluorescence (XRF) methods to see the mercury levels that had been scattered in the research location. The study aims to determine the distribution of mercury waste and its levels. This research includes sampling, sample testing, data processing and analysis, and making maps of the distribution of mercury waste through QGis software. From the study, it was found that the distance from the traditional gold mining processing location determines the concentration level (Hg). Analysis using AAS shows that there were 13 samples had mercury concentrations above the critical threshold. From the analysis, it is also known that AAS could not detect mercury levels in soil samples which is different from the results obtained using XRF.
