<![CDATA[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.]]>

<![CDATA[This research aims to find out the quality of the water as it had been filtered from the single of active carbon, silica sand and gravel as the media filter. And also to know the quality of the water as it had been filtered from the combination of active carbon, silica sand and gravel as the media filter. The quality of the water filtered was measured by both physic and chemistry parameters, either parameters were measured and observed directly at the Modern Physic Laboratory of Science and Technology Faculty and at the Physic Chemistry Laboratory of  Science and Technology Faculty. The quality of the water which had been filtered by the aforementioned filter materials then met the requirement as pure water based on the water authentic quality standard (South Sulawesi Governor Rule Number 69, 2010), the water then can be used for the daily household necessity such as bathing, watering plant, laundry, and so forth.]]>

<![CDATA[This research aims to determine the level of water quality in  Saloe rivers based physical test of color, smell, temperature, taste, conductivity, and total dissolved solids. Sampling was conducted at three sites by measuring the depth of the river and take samples at the surface, middle and bottom of the river. Tests conducted in the laboratory of Chemistry, Faculty of Science and Technology is using descriptive method by measuring the standard measuring tool. From the results of water quality testing at each sampling site, there was information that the water quality of the Saloe rivers can be classified into categories of water quality is good because all the parameters tested still achieve water quality standards based on Government Regulation No. 82 in 2001.]]>

<![CDATA[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.]]>

<![CDATA[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).]]>
