Penggunaan Metode Taguchi untuk Menentukan Kondisi Parameter Optimum Pada Pembuatan CaO dari Batu Kapur (CaCO-3)

Research has been carried out to determine the optimum conditions for making quicklime (CaO) using Taguchi Method. CaO is burning result of limestone (CaCO_3) in calcination process by releasing CO_2 gas until solids occur. The was calcined at 950^o c. Method a quality improvement technique with selection most influential parameters CaO. are particle size, mass, heating temperature and stirring time. XRF results show that levels after design increased from 98.779% 98.814%. XRD phase amorphous. which were formed Lime (CaO), Quartz (SiO_2) Hematite (〖Fe〗_2 O_3). Based on SEM results, morphology CaCO_3 an irregular size tends be granular solid due presence impurity. Meanwhile, EDS analysis content Calcium (Ca) quite high. From Method, obtained 140 mesh, 75 gr 70^o c time 0,5 hour.
