Abstract: The Latuhalat coastal area is the headland area of Ambon. This area is very important to know about the potential of geological disasters in the area. The potential of geological disasters can be know by analysing the mineral characteristics based on the FTIR method. Analysis results of the three type of rock samples by the spectrum produced in accordance with peaks formed by a functions group. M1 samples with wave number between 3565 cm-1-3595 cm-1 which is formed by O-H functional groups, that can identify that the types of minerals are kaolinite and amphibole. M2 samples with wave number between 1500 cm-1-1570 cm-1 which is formed by the C=C functional groups, that can identify that the type of mineral is quartz. M3 samples with 1700 cm-1 which is formed by the C=O functional group, that can identify that the type of mineral is calcite. So it can interpretation that the type of rock in the Latuhalat coastal area are granite, pumice and limestone. Based on the type of rock such as granite, pumice and limestone in the area of research, it can be interpreted that in the Latuhalat coastal areas ever occurred geological disasters. Geological disasters that can occur in the area are the storm surge and flood tides. Where at the beginning of pumice and limestone that comes from the swept sea by a storm surge to the coastal area.
Keywords: FTIR method, wave number, functions group, mineral, geological disasters.
