Abstract

Sintesis nanokristal perak telah berhasil dilakukan menggunakan ekstrak kulit buah manggis (Garcinia mangostana L. ). Proses sintesis dilakukan dengan mencampurkan larutan AgNO3 1 mM dengan 2,5 mL ekstrak kulit buah manggis dan ditambahkan dengan 12 mL PEG 3%. Larutan AgNO3 yang digunakan memiliki variasi 35, 40, 45, 50, dan 60 mL, diaduk dengan menggunakan magnetic stirrer selama 3 jam kemudian dilakukan sintering dengan suhu 500 ˚C selama 1 jam. Sampel dikarakterisasi menggunakan XRD (X-Ray Diffraction), SEM (Scanning Electron Microscope), dan FTIR (Fourier Transform Infrared). Berdasarkan hasil XRD, nanopartikel perak yang dihasilkan memiliki ukuran kristal berkisar antara 32,29 nm – 126,55 nm dengan struktur kristal kubik FCC (Face Centre Cubic). Selai itu, terdapat kecenderungan bahwa semakin kecil volume AgNO3 yang digunakan, ukuran nanokristal perak yang dihasilkan juga akan semakin kecil. Berdasarkan hasil SEM , nanopartikel perak yang dihasilkan masih terdapat gumpalan. Kondisi optimum dengan ukuran kristal paling kecil didapat pada jumlah AgNO3 35 mL dengan ukuran kristal 32,2908 nm.
