• Untuk mengetahui ukuran kristal dari
hasil XRD dapat dianalisis
menggunakan metode Scherrer:
• Karakterisasi menggunakan FTIR
berfungsi untuk mengetahui gugus
fungsi yang terkandung di dalam
sampel melalui banyaknya frekuensi
yang melewati senyawa yang terukur
dalam persen transmitansi .
Dengan, k : bilangan konstanta (0,9)
λ : panjang gelombang sinar x
B : nilai setengah puncak atau FWHM
Ɵ : sudut Bragg
X-RAY DIFFRACTION (XRD) Fourier Transform Infrared (FTIR)

• Scanning Electron Microscope (SEM) adalah
salah satu jenis mikroskop elektron yang
menggunakan berkas elektron untuk
mengamati morfologi dan ukuran pori dari
sampel (Abdullah, 2005).
High Performance Liquid Chomatography
(HPLC)
• HPLC merupakan suatu metode yang sensitif
dan akurat untuk penentuan kuantitatif dan
kualitatif serta baik untuk pemisahan senyawa
yang tidak mudah menguap seperti asam
amino, protein, peptisida dan lain-lain
(Nurhamidah, 2005). HPLC digunakan untuk
menentukan berapa banyak kafein yang masih
tersisa pada sampel.
