Abstract

Doping ion Zn2+ x = 0,3, 0,5 0,7 dan 0,9 pada material magnetik Barium M-Heksaferrit (BaM) telah berhasil disintesis dengan metode solid state reaction. Material konduktif polianilin disintesis menggunakan metode polimerisasi dengan dopan DBSA.Material RAM dikarakterisasi melalui X-Ray Flourescence (XRF), X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR), Four Point Probe (FPP), Scanning Electron Microscope (SEM) dan Vector Network Analyzer (VNA). Fasa BaM terbesar diperoleh pada BaM x 0,9 yaitu 95,98%. Penambahan konsentrasi doping Zn2+ tidak berpengaruh secara signifikan pada konduktivitas listrik BaM. BaM/PANi digunakan sebagai filler pada matrik cat kapal untuk membentuk material komposit. Pelapisan pada plat baja kapal grade A tipe AH-36 dilakukan dengan metode casting menggunakan desain pelapisan multilayer 4 mm. Desain multilayer meningkatan nilai rugi reflesksi dan pelebaran pita penyerapan rentang X-Band (8,2-12,4 GHz). Rugi refleksi terbesar diperoleh dari pelapisan BaM x 0,9yaitu -39,004 dB, sedangkan pelebaran pita serapan terbesar diperoleh dari pelapisan BaM x 0,3yaitu 3,4 dB. Berdasarkan hasil penelitian yang diperoleh dengan penambahan konsentrasi doping Zn2+ maka cenderung meningkatkan daya serapan material RaM. ======================================================== Doping ion Zn2+ x = 0,3, 0,5, 0,7 and 0,9 on the magnetic material Barium M-Hexaferrites (BaM) has succesfully synthesized by solid state reaction method. Polianilin conductive was synthesized using polymerization method with DBSA dopan. RAM were characterized by X-Ray Flourescence (XRF), X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR), Four Point Probe (FPP), Scanning Electron Microscope (SEM) and Vector Network Analyzer (VNA). The maximum BaM phase that is 95,98% obtained at BaM x 0,9. Addition of doping Zn2+ concentration just give a little effect on BaM electrical conductivity. BaM/PANi used as filler on the matrix of marine coating to make a composite materials. Coating on steel ships grade A type AH-36 done with the casting method using design multilayer 4 mm. Multilayer is effective to increase the reflection loss and absorbtion bandwidth on X-Band range (8,2-12,4 GHz). The reflection loss maximum that is -39,004 dB obtained at BaM x 0,9, while the maximum absorbtion bandwidth is 3,4 dB at BaM x 0,3. Based on this experiment we know that addition of doping Zn2+ concentration can be increased the potential absorbtion of RAM materials.
