Abstract

AbstractTopographic modelling is an important aspect in engineering work and planning such as dam design, road planning, volumetric calculation, water flow analysis and so forth. To get topographic data, usually a land survey or topographic measurement is taking for a region or an area under study. A number of points that represent an area are measured to get a height dataset. The dataset which is consist of height points will be used to model topographic condition of the area with generating contour map and also 3D model. There are some methods can be used to generate topographic surface in 3D model like linear interpolation in Triangular Irregular Network (TIN), Kriging and Inverse Distance Weight (IDW). This research implemented IDW spatial interpolation algorithm to model earth surface or topographic model in 3D. The IDW method was implemented in Python programming language using Numpy library for computation and Plotly graphic library to visualize the 3D Model.  Using 2500 and 10000  interpolation points with 100 random sampling points that extracted from Digital Surface Model (DSM), IDW was successfully estimated the height at unsampled locations. The results show, more higher interpolation point number will produce more detail surface texture.  Keywords : IDW, Topographic, 3D Modelling

Abstract

Industrial activities have led to the aquatic environment degradation. One of the pollutants is lead (Pb) which has a dangerous toxic effect, cannot be decomposed and is mutagenic. High levels of Pb in waters can result in the death of aquatic biota and pose a threat to human health. This study examined the ability of the Jeringau plant (Acorus calamus) to absorb Pb. The Jeringau plant is taken from the river bank, with a length of 20 cm, has many leaves and roots. Artificial Pb waste was made with various concentrations of 0.5 mg/L, 1 mg/L and 2 mg/L. Furthermore, the Jeringau plant was put into a reactor containing Pb waste and observed for 9 days. The obtained results showed that Pb concentration decreased at the ninth day of 0.03 mg/L, 0.067 mg/L and 0.201 mg/L.

Abstract

Hydrocarbon prospect area research has been done in North Aceh at two locations. The research aims to analyze subsurface litology using  resistivity method. Data acquisition of each location was presented by 330 m line survey. The acquisition process was generated by Super Sting R8/IP and modelled by EarthImager 2D. Oil and gas (NA1) resistivity section showed anomaly at 170 m (x) and 17 m (z) that was identified as minor fault. However, oil seepage was not founded on the location. Fossil locality (NA2) section showed a contrast vertical anomaly (16-90 Ωm) around 90 – 120 m that was identified as a way for the seepage.

Abstract

Beutong is a commercial origin of various kinds of Jade (Giok) in Aceh Province. From the geological view the formation of jade is due to the mélange zone. The zone is usually an assemblage of a variety mineral composition. The paragenetic minerals of the jade can be divided into four categories, which are Jadeite, Nephrite, Serpentine and Vesuvianit. The characteristics of the color were associated with a variety of constituent minerals which can be red, yellow, brown, gray, and black. Thus, by this paper we classified the jades based on their mineral constituents.

Abstract

It has been conducted a geo-electrical resistivity survey at geothermal area of Ie Jue, Aceh Besar.  The survey aims to measure resistivity value in the area. It is expected that the values of resistivity will image the subsurface structure in the area. In addition geological features in the area are shown after we process it. The data acquisition in this study was acquired using a SuperSting R8/IP resistivitymeter and its data processing using EarthImager 2D software to get the image of resistivity pseudosection. The two lines of measurement crossed the surface geothermal manifestation. Each line has 330 m in length, and 56 electrodes with electrode space of 6 m. The result of resistivity pseudosection model interpreted based on geological condition and observation in the area. Resistivity pseudosection model shows the study is water-saturated (64.0 Ωm) to a depth of ±65 m and a highly conductive zone (0.6-3.5 Ωm) with a thickness of 30-50 m. This conductive layers below the embodied surface at a distance of 158-160 m on the IJ-Y1 line and at a range of 130-185 m on the IJ-Y2 line. This conductive zone is indicated as a weak zone where geothermal fluids are transported to the surface.Keywords: Geothermal, Ie Jue, geo-electrical resistivity survey, resistivityREFERENCES          Bennet, J.D., Bridge, D.McC., Cameron, N.., Djunuddin, A., Ghazali, S.A., Jeffrey, D.H., Kartawa, W., Rock, M.N.S., Thomson, S.J., Whandoyo, R., 1981.

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.
