Extraction of softwood pine (Pinus merkusii) as the main ingredient for the manufacture of nanocellulose was carried out through the acid hydrolysis method. In this research, four samples were made with varying concentrations of H2SO4. The samples that have been made have been tested by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Fourier Transformed Infrared (FTIR). XRD diffractograms were analyzed qualitatively and quantitatively. XRD analysis shows that the greater the concentration of H2SO4 used, the percentage of purity of each sample increases. The phase identification results show that the samples with the addition of 19, 29, and 39% H2SO4 form Iɑ, Iꞵ, and lignin phases. While in the sample with the addition of 45% H2SO4, only Iɑ and Iβ phases are formed. Image identification from SEM test results shows that the image pattern has a distribution shape structure resembling a compact and overlapping arrangement of stone slabs. FTIR analysis shows the functional groups formed are O-H, C-H, C≡C, C=C, H-C-H, C-O, and C-O-C, which indicates the presence of cellulose.
