Rochelle Salt is the first synthesis Crystal made by Pierre Siegnette La Rocchelle in
France. Rochelle Salt has several characteriztion, one of characterization is piezoelectric
effect where the crystal can change the kinetic energy to electrical energy. Nowaday,
piezoelectric effect plays the role in advancing the rewenable source energy. Rochelle
Salt can be created using tartar cream and washing soda reacted with distilled water as
a solvent. The solution was reacting until there was no more reaction or
supersaturation condition. In the crystalization process, the solution waited for 2 days
until the crystal seed appeared. The crystal growth process was using the method of
growing crystal in solution for 1 month until the crystal bigger enough for research to
dicovered the piezoelectric effect. Based on the result that have been obtained,
Rochelle Salt had piezoelectric effect. In the analysis process, crystal was hit using
wooden hitter and metal hitter, the voltage was increase when the crystal is hit by
hitter. The piezoelectric effect in crystal also disappeared toward time.
