    Abstract
    Telah dilakukan pembuatan bonded magnet permanen BaFe12O19 - NdFeB dengan penambahan resin epoksi ( 3, 5, 7, dan 9 % wt). Beberapa aplikasi dari magnet tersebut diantaranya adalah digunakan pada generator listrik, motor listrik radio, televisi, komputer. Tujuan penelitian ini adalah untuk mengetahui pengaruhnya penambahan BaFe12O19 - NdFeB dengan Resin Epoksi terhadap sifat fisis , sifat magnetik dan mikrostruktur. Proses preparasi bahan baku mulai dari pencampuran serbuk BaFe12O19 - NdFeB dicampur bahan perekat resin epoksi sebanyak ( 3, 5, 7, dan 9 % wt) dan dicetak dengan gaya 4 tonf dengan menggunakan Carver Hydraulic Press sehingga membentuk pellet. Sampel yang telah dicetak kemudian dikeringkan dengan temperatur 80°C ditahan selama 1 jam. Karakterisasi yang dilakukan meliputi pengukuran bulk density, microstructur menggunakan Optical Microscope, nilai fluks magnetic dengan menggunakan gaussmeter dan sifat magnet dengan menggunakan VSM. Dari hasil karakterisasi secara keseluruhan diperoleh kondisi optimum pada komposisi bonded magnet BaFe12O19 - NdFeB adalah variasi Resin Epoksi 3%wt. Sifat-sifat bonded magnet BaFe12O19 - NdFeB tersebut adalah bulk density = 4,93 g/cm3, fluks magnetik = 869,9 Gauss, dan BHmax 3,71 MGOe.
     
    Has been made a permanent bonded magnet BaFe12O19 – NdFeB by adding Epoxy Resin (3,5,7,9% wt). Several applications of that magnet in between has been used to an electrical generator, radio electrical motor, television, computer. The purpose of this research is to know the effect of adding BaFe12O19 – NdFeB with Epoxy Resin to the physical character, magnetic character, and microstructure. Preparation process of raw material of mixing BaFe12O19 – NdFeB powder with Epoxy Resin about (3,5,7, and 9% wt) and printed with 4 tonf style by using Carver Hydraulic Press, so that become a pellet. Sample which is printed then being dried with temperature about 800C in an. The characteristic which is done is about measuring bulk density, microstructure, using Optical Microscope, the flux magnetic value by using Gaussmeter and the magnet characteristic using VSM. From the characteristic over all obtained optimum condition at the bonded magnet is BaFe12O19 – NdFeB is the variation of Epoxy Resin 3% wt. The characteristics of bonded magnet BaFe12O19 – NdFeB is bulk density = 4.93 gr/cm3, flux magnetic = 869,9 Gauss, and BHmax 3.71 MGOe.
