N2 - This research aims to develop an easy, simple, and cheap method to determine aluminum by Microfluidic Paper-based Analytical Device (PPAD) with natural reagent from the heartwood of Caesalpinia sappan Linn extract. This method's principle is based on the formation of the red complex as a product reaction of aluminum and brazilein from the heartwood of C. sappan Linn extract on the PPAD. The method optimizations were done to determine the optimum conditions of sample volume, reagent concentration, and reaction time. The resulting optimum conditions were 10 PL for sample volume, 1.6 % (w/v) for reagent concentration, and 10 min for reaction time. Under the optimum conditions, good linearity was found at aluminum concentrations of 0 - 40 mg/L (R2 = 0.9906) with the detection limit of 4.46 mg/L. The selectivity test was done by investigating the effect of Ca and Mg ions on the measurement of aluminum. The method showed that the tolerable concentrations for Mg2+ and Ca2+ ions were up to 60 mg/L.
