Abstract

This study aims to determine the quality of the composite board from a variety of compositions. The sample composition consisted of 50% polypropylene plastic: 50% rice husk, 60% polypropylene plastic: 40% rice husk, 70% polypropylene plastic: 30% rice husk and 80% polypropylene plastic: 20% rice husk. The method used in this research is physical test and mechanical test. As for the results of the physical properties test, the density test of all compositions meets the standards starting from the low, medium and high density composite board category. To test the moisture content of all compositions meet the standards. Meanwhile, in the water absorption test, there was no composition that met the standards. For the thickness change test, all compositions met the standards except for the composition of 50% polypropylene plastic: 50% rice husk. The test results for the mechanical properties of all compositions do not yet meet Indonesian national standards.

Abstract

This research aims to devise means of garbage in the river automatically and see the effectiveness of these tools. Model design made consists of conveyance of trash and garbage disposal apparatus. The working principle of this tool is if a light sensor that is placed in front of the tool covered with garbage that floats on the surface of the river. Waste transported lifted up and thrown into the garbage disposal apparatus transverse position under the position of conveyance of garbage. The results obtained from the design tool of garbage in the river is automatically obtained the maximum load that can be transported 1505,9 N while only able to practice 11,51 N with effectiveness 0,76% so that the tool is still less effective.

Abstract

Research already did by resistivity method (custody species) schlumberger configuration that aim to know of rocks bottom surface structure in alteration zone are district of Gunung Kidul D.I Yogyakarta. Measurement points this research was measured as many as nine sounding points with each disquisition long were 75 m, 100 m and 120 m. the result of interpretation showed that of rocks bottom surface structure in alteration zone area were closed mantle (soil) with resistivity value 9,57 Ωm 14 Ωm on depth (0 – 0,75) m, , clay stone (6,86 – 42,1) Ωm in depth (0 - 9,22) m, sand stone (0,966 – 3,44) Ωm in depth (2,79 – 21,7) m, larva (841 – 1703) Ωm in depth (9,48 - ∞) m. Lava that had alteration was marked by resistivity value which small relative compared with lava which still fresh, this is due to lava which has alteration in area this suspected contain mineral metal so that reisitivity value smaller. lava which had alteration was there in point 1,4 dan 5 with resistivity value 40.5 Ωm – 95.2 Ωm in depth 0 m -∞. While at point 2, 3, 4, 6, 7, 8, 9 there type some structure is: closed mantle (soil), clay stone, sandstone and lava.

Abstract

This study aims to determine whether the plastic waste can be used as an alternative fuel and to determine the physical quality of alternative fuels plastic waste generated before distillation and after distillation. This study is done the combustion process using a tool designed himself. After the burning process, the oil obtained is done by testing physical parameters are density, viscosity and caloric value. The results showed that the physical quality of alternative fuels, namely plastic waste For this type of plastic PET, HDPE, LDPE, PVC and PP in density test results obtained before and after distillation not meet fuel standards. The results obtained on testing the viscosity value for the type of plastic PET, LDPE, PP and PVC before distillation including kerosene fuel standards. Whereas For this type of plastic HDPE and PP after distillation including kerosene fuel standards. While the test results obtained calorific values for the type of plastic PET, HDPE, PVC, LDPE and PP before and after distillation not meet fuel standards.

Abstract

This study aims to determine the physical quality of the alternative fuel used oil waste generated by the distillation process and to know how big the resulting efficiency distillation apparatus for the purification process used oil waste . This research was conducted by first designing a simple distillation apparatus and then burning twice with such a simple distillation apparatus . After the burning process is done testing the quality of the physical form of the density, viscosity and caloric value that previously had to be done first physical quality testing on used oil with the same parameters. The results obtained for each parameter before and after distillation is to density (860-864 kg/ ) and (760-761 kg/ ); for viscosity (20°C = 0,8374176,743 Poise, 40°C = 124,445 Poise, 60°C = 15,995 Poise); and (20°C = 0,8374 Poise, 40°C = 0,7268 Poise, 60°C = 0,3273 Poise); and to the calorific value (1.483 J) and (1.542 J). The results showed that the density parameter for testing and quality standards ( specifications ) of gasoline fuel . While testing the viscosity parameters and quality standards ( specifications ) type fuel kerosene . And to the calorific value obtained does not meet the standards and quality ( specifications ) of any type of fuel , but approaching the calorific value of the fuel type of gasoline.

Abstract

This research aimed to identify the location of accumulation and distribution direction of the spread of leachate at landfills Tamangapa around Makassar Multichannel Resistivity meter resistivity measurements using the form of the voltage injected into the subsurface through a predetermined trajectory as much as six trajectory. The method used is Geolistrik resistivity method with Wenner-Schlumberger configuration. Data processing is done by using RES2DINV to generate a 2D cross-section of data below the surface, and use Voxler 3 to determine distribution direction and location of the accumulation of leachate seepage of leachate . Based on the location of the results obtained by the accumulation of leachate generated from landfill waste decomposition Tamangapa Makassar interpreted to be at a depth of 2.50-18.52 m with apparent resistivity values from 0.0090-5.00 Ωm at coordinates 5017'727''LS and 119049'084''BT elevation 16-20 m above sea level. While the distribution of leachate seepage direction around Tamangapa Makassar interpretation in sector 1 seepage eastward direction which is at coordinates 5017'594''LS and 119049'202''BT with a depth of 2.50-12.80 m. In the second sector is interpreted towards see page of leachate to the west which is at coordinates 5017'727''LS and 119049'084''BT with a depth of 2.50-31.87 m.

Abstract

This study aims to determine the effect of NaCl concentration of sea water on the value of voltage and electric current, the amount of power produced from seawater with various concentration and duration of sea water can be utilized as a source of electrical energy. Plate copper (Cu) and plate zinc (Zn) as the electrode and the concentration of NaCl sea water used were obtained from three point locations is Tanjuang Bayam coast, Barombong coast and Je’ne’berang river estuary. The results was show that the concentration of NaCl seawater affect the amount of voltage and current value of the electricity generated is greater concentration of NaCl seawater used, the greater the voltage and electrical current was generat. For the highest concentration was obtained at the point of Cape Shaded locations with large concentrations of 3,4% and a maximum power generated 0,21072 watts while the lowest concentration was obtained at the point of estuaries Jeneberang locations with large concentrations of 3,2% and a maximum power generated 0, 20 331 watts. Effective time used for the utilization of sea water which is the average for ten days to turn on the LED (Light Emithing Dioda).
