Abstract
One of an effective and quickly method has been established to measure total porosity of the rocks. Macro file (jPOR.txt) for ImageJ is an utilises, which can be used on digital photomicrographs. The method can be run entirely using free to download software because there is no specialized scientific equipment. Digital photomicrographs are acquired from MicroCT Image Scan (MIS). Images were processed using a newly developed custom 8-bit palette and analized for porosity in ImageJ using the simple to use jPOR macro. The method directly calculates total porosity for batches of images with or without the option of user adjustment. Results are showing some images and calculation of the total porosity. This method have been succeeded applying in the carbonate rock images of Taccipi Limestone, South Sulawesi.
