Karakterisasi Batu Kapur Alam Bukit Jimbaran Bali

Abstract

This research is about the characterization of naturar limestone in the Bukit Jimbaran area of Bali. The aim of this research was to learn chemical composition and micromorphology of Bukit Jimbaran limestone. The research was conducted in sequential steps as described below i.e. the limestone was grinded and sieved in size of 0.25-0.50 mm. Fine limestone, then was heated by using oven at 1000 C for 24 hours and analyzed by FTIR, XRD and SEM. The Spectra of FTIR showed that O-H, C-H, and C-O were dominantly functional groups, which composed CaCO3 and CaO. The results of CaO crystal measurements using Scherrer equation is 51,39 nm. Micromorphology observation by using SEM showed size shaped (vaterite) of Bukit Jimbaran limestone

“…The initial indication is marked by the occurrence of OH, CO, CH, and CaO functional groups, observable in the spectral regions of 4,000-2,100 cm -1 and 1,900 cm -1 . The second indication involves the CO functional group, evident in the 2,000-1,500 cm -1 range (Ulfa et al, 2019). The outcome of the FTIR analysis is depicted in Figure 2.…”
