Abstract
NdFeB magnets are usually used in lowspeed generators. Another alternative that can be used is BaFe12O19. A study has been carried out using the sintering process to obtain the value of the magnetic energy of BaFe12O19. The magnetic energy data obtained were processed using Multiple Linear Regression Analysis to examine the relationship between the sintering process and magnetic energy in increasing the magnetic properties of BaFe12O19. The predictor variables are temperature, T (deg C) and time, t (hours), and response variable is magnetic energy. The temperature levels are 750 deg C, 800 deg C and 850 deg C and the time levels are 8 hours, 10 hours and 12 hours. It was found that there was a very significant relationship between the sintering process and magnetic energy in increasing the magnetic properties of the permanent magnet BaFe12O19 (pvalue > 0.01) and R2 = 83.61%. The resulting model can be used to predict the average value of magnetic energy if the sintering process is carried out at a certain temperature and time. If the temperature is 900 deg C and the time 10 hours, the predicted mean value of magnetic energy is 113.611 T.kA/m. Keywords Permanent magnet, sintering process, magnetic energy, multiple linear regression and significant.
