Keywords:
Komponen magnet, Bahan baku oksida lokal, Perangkat elektronika, Kemandirian industriSynopsis
Naskah orasi ini mengulas komponen magnet berbasis bahan baku lokal dengan inovasi teknologi dan aplikasinya pada perangkat elektronika. Bahan lokal yang dimanfaatkan adalah pasir besi, limbah HSM dan limbah las dengan terlebih dahulu melalui proses pemurnian. Sebagai bahan perbandingan, riset juga menggunakan bahan kimia murni dengan hasil karakteristik magnet yang sama dengan bahan lokal. Jenis magnet yang telah dibuat adalah magnet ferit lunak dan magnet keras, magnet bonded NdFeB, magnet bonded hybrid NdFeB, ferofluida, dan nanopartikel magnet Fe3O4. Teknologi yang telah dilakukan dan dikuasai adalah metalurgi serbuk, sol-gel, hot press, sonikasi, dan kopresipitasi.
Penelitian menekankan pentingnya pemilihan bahan baku, proses pemurnian, dan metode sintesa yang tepat guna mengoptimalkan sifat magnet dan memastikan kesesuaian dengan aplikasinya pada perangkat elektronika. Magnet hasil riset ini telah diaplikasikan pada bidang pangan, telekomunikasi, energi dan bidang lainnya yaitu pada perangkat sirkulator, transformator, motor DC, generator magnet permanen, magnetic separator, flow meter, sensor, dan electromagnetic energy harvester. Hasil riset pembuatan magnet ini diharapkan dapat mengurangi ketergantungan produk magnet impor sehingga dapat mendukung kemandirian industri elektronika nasional.
