Abstract

Telah dilakukan sintesis nanopartikel Magnesium Oksida (MgO) dengan metode presipitasi. Nanopartikel MgO disintesis menggunakan Polietilen Glikol (PEG) yaitu PEG 2000 (sampel 1), PEG 4000 (sampel 2), dan PEG 6000 (sampel 3) sebagai template dengan suhu sintering 600 C selama 3 jam. Sampel dikarakterisasi dengan menggunakan X-Ray Diffraction (XRD) untuk mengetahui ukuran dan struktur kristal, sedangkan Scanning Electron Microscopy (SEM) digunakan untuk mengidentifikasi morfologi permukaan sampel. Hasil karakterisasi XRD menunjukkan bahwa ukuran kristal pada sampel 1, sampel 2 dan sampel 3 berturut-turut adalah 66,76 nm, 74,15 nm, dan 66,79 nm. Hasil SEM menunjukkan bahwa masih terdapat penggumpalan (aglomerasi) antar partikel MgO pada ketiga sampel. Semakin besar berat molekul PEG, maka semakin besar pula persentase puncak nanopartikel MgO yang dihasilkan.
