<![CDATA[The aim of this research is to determine the effect of micro-sized carbon material mass variation from coconut shell leftovers or wastes reinforced with filter paper towards Fe filtration of Mataram canal water. Preparationand synthesis of the micro-sized carbon material is conducted via liquid sonication exfoliation (LSE) method using two main equipments, i.e.: a blender and a self-custom made piezoelectric-based ultrasonication apparatus, and then incorporated into a simple filtration apparatus. UV-Vis spectroscopy characterization is done on the micro-sized carbon material solution, while atomic absorption spectroscopy (AAS) is done on samplesof Mataram canal water before and after Fe filtration with mass variation of the micro-sized carbon material. The UV-Vis results show that increasing the mass of the micro-sized carbon material increases the absorbancevalues at the same wavelength. The AAS results confirm that the greater the mass of the micro-sized carbon material the smaller the Fe content inside the water samples after filtration. The lowest Fe content of 0.016 ppm is obtained for 3 grams of the micro-sized carbon material.]]>
