Abstract

This research aims to determine the mineral content of activated charcoal made from kluwak seed shell, the quality of activated charcoal made from kluwak seed shell, and the absorption capacity of kluwak seed shell charcoal as adsorbent of polluted well water after testing. From the results of XRF analysis, it can be seen that there are still several types of impurities in activated carbon shells of kluwak seeds. It can be said that the activated carbon obtained is not yet fully pure activated carbon because pure activated carbon only contains 100% carbon. Where the quality of activated charcoal made from kluwak seed shells meets the requirements of SNI-06-3730-1995 in terms of water content and ash content. And the absorption capacity of Kluwak sage shell charcoal as an adsorbent of contaminated well water after testing, namely the gravel, activated carbon, and silica sand have met the clean water eligibility standards when viewed from turbidity and color while in the gravel filter layer, silica sand, carbon and in the silica sand filter, activated carbon, gravel have not met the eligibility requirements for clean water because of the high turbidity and the solid color.

Abstract

Port construction at Pantoloan has influenced the condition of port and its environment. The hidro-oceanography process has influenced the condition of water, especialy to the wind and wave condition. This research was aimed to know wind condition and wave characteristic at Pantoloan, Palu, Central Sulawesi. The method used in this research was the measurement of wave current using quantitative data processing from the ECMWF (European Center For Medium-Range Weather Forecasts) website for 10 years. The study results showed that the highest wind speed is the wind blowing from the northwest at 1.34 m/s. Wind directions that have potential to generate waves are wind from the north, northwest, west and southwest. Meanwhile, deep sea waves that occurred most frequent on study location were waves from the north (23.92%), followed by the Southwest (35.70%), the Northwest (3.70%) from the West (4.65%), and the Northeast (18.83%), the South direction is (8.08%), the Southeast direction is (2.61%), and the East direction is (2.50%) with a wave  length interval of 0-0.3 m and a period of 5 - 7.5 seconds.

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. Keywords: geoelectric, Wenner-Schlumberger configuration, geothermal

Abstract

This research is about the e / m electric charge ratio with the aim of (1) to determine the relationship between accelerator potential and current strength and electron beam radius, (2) to determine the value of e / m for electron particles based on calculation results and graphs. . This research uses a cathode tube and a coil which functions to generate a magnetic field. This coil is called a Helmholtz coil (a coil that has a radius equal to the distance of the two coils). Based on the research results, it was found that (1) the greater the potential value of the accelerator, the smaller the value of the electron beam radius, and vice versa, if the smaller the potential value of the accelerator, the greater the value of the electron beam radius. whereas the acceleration potential relation to the electron current strength, if the value of the accelerator voltage is enlarged, the strength of the electron current will also be greater, and vice versa; (2) the average e / m value of the calculation result is 1.67 × 1011 C / kg and the average e / m value of the graph is 1.66 × 1011 C / kg. While the percent (%) difference in the value of e / m in literature with the results of calculations and graphs is 0.05% and the percent (%) of the difference in the value of e / m in calculations with the results of the graph is 0.001%.
