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

This research aims to design and design an automatic water filter and test the quality of the filtered water using an automatic filter that has been designed. The quality of the filtered water is viewed from physical and chemical parameters, both parameters are measured and observed directly at the Modern Physics Laboratory of the Faculty of Science and Technology and the Physical Chemistry Laboratory of the Faculty of Science and Technology. Based on the results of the study, it was found that the results of water quality in an automatic water filter with proof of two different samples showed that the water produced was not maximal because it had a high conductivity value and a pH value that was in the acid category. Because the water pressure that enters the filter media is too large it can stir / destroy the top layer of the filter so that the top filter cannot filter out impurities optimally.
