Abstract

Sub-surface analysis has been conducted to find out the lithology which includes the structure, the type of rock and the thickness of the geothermal layer of geothermal resources by using the geoelectric configuration method of Wenner-Schlumberger in Kalompie Hamlet, Galung Village, Barru sub-District, Barru District. The working principle of the geoelectric method is performed by injecting an electric current to the ground surface through a pair of current electrodes and measuring the potential difference with another pair of electrodes. The research was conducted in three trajectories with a trajectory length of 105 m and a spacing of 7 m electrodes. The result of the data interpretation was obtained by three materials that is sandy soil with resistivity value 0,095 - 4,05 Ωm have thickness 1 - 12 m, tuffed sandstone with resistivity value 4,05 - 39,7 Ωm having thickness 10 - 14 m, with a resistivity value of 39.7 - 547 Ωm with a thickness of 5 - 15 m, this rock is suspected as a rock cover on Kalompie hot water source area because it has a difficult nature to pass water (impermeabel). The geological structures of fault, anticline and syncline are not found in this research because the measurement path does not cut or pass through the path of geological structure.

Abstract

This research was carried out on the Maros-Bone axis road in Sawaru Village, Camba sub-district, Maros district, South Sulawesi. This area is one of the areas prone to ground movement. This is because this area has a hilly and humid geographical condition. To find out the subsurface conditions, a research using the 2-dimensional type geoelectric resistivity method with the Wenner configuration. The results of the analysis and interpretation of the 2-dimensional cross section shows that the Camba sub-district which consists of clay rock, alluvium rock, gravel, compact sedimentary rock, and ground water and the point of dosing is at a depth of 8 meters. This layer has a resistivity value between the resistivity value of 2.71 5,m-5.78 Ωm which is characterized by water-saturated clay rocks and can cause landslides at any time because of the pressure from the top of the rock with a large value of resistivity. The slip plane is marked with clay rock at a depth of 4 meters-8 meters. This type of avalanche is a rotational avalanche.

Abstract

A research was conducted at Steam Power Plant (PLTU) of PT. Semen Tonasa in which the coal burning resulting waste that is dust, fly ash and bottom ash. This research aimed to find out how much solid waste was resulted and how was the characteristic. Based on the secondary data obtained, it was found out that this Steam Power Plant results 96,07 ton of fly ash dan 41,62 ton of bottom ash in a day. Then a test was conducted in laboratory with elemental content analysis method using XRF showing that the highest element was silica and iron while as the calculation result of LOI content, it was found that fly ash had low content of carbon so that it is good to use as mixture of cement. Meanwhile, bottom ash contained high content of carbon so that it is fit to apply with polymer materials. Furthermore, the analysis was continued using XRD method and found that fly ash BTG I was dominated with Davyne mineral phasa with hexagonal crystal structure. Bottom ash showed bavenite phasa with orthorhombic crystal structure. Meanwhile, at BTG 2, fly ash showed Quartz phasa with trigonal crystal structure (hexagonal axes) and for bottom ash, there was Berlinite phasa with trigonal crystal structure (hexagonal axes) and Gillespite phasa with yang orthorhombic crystal structure. Key Word: PLTU, Fly Ash, Bottom Ash, LOI, XRF, XRD

Abstract

Was research on Dye Sensitized Solar Cell to determine the effect of concentration Henna leaves pigments (Lawsonia Inermis L.) on the efficiency of DSSC. The solar cell is made with a sandwich structure, the dye used is made in three variations of concentration is concentration of 10 %, 20 % and 30 %. TiO2 deposition on ITO glass made using the method of doctor blade with a cell area of 2.25 cm2 for 24 hours of immersion in the dye. Based on the results of measurements of I-V by using a source of light, DSSC efficiency for dye obtained with a concentration of 30 % which is 0.003366667 %, to dye with a concentration of 20 % is 0.0033264 % and to dye with a concentration of 10 % which is 0.000312 %. This research can be concluded that the higher the concentration of dye used, the higher the efficiency of DSSC generated. Keywords: dye, efficiency, henna leaves, solar cells.
