Leang Lonrong Cave with underground river flowing in it is located in Maros-Pangkep karst area known with a high level of annual rainfall. Based on this valuation, karst rocks in the Maros Karst Area can be recommended reservoar and karst rocks in the Pangkep Karst Area can be recommended as aggregate limestone. The valuation of the physical properties of rocks in the Maros Karst Area have special quality (5-50%), sufficient quality (10-15%), poor quality (5-10%), and negligible quality (0-5%) and in the Pangkep Karst Area has negligible quality (0-5%). There are differences in physical properties of rock in the Maros Karst Area and Pangkep Karst Area based on an independent sample t-test. The Pangkep Karst Area obtained dolomite limestone with density values of 2.47-2.65 g/cm3 and porosity of 0-5%, indicating primary porosity. The analysis results of the physical properties of rocks in the Maros Karst Area obtained modified limestone and dolomite limestone with density values in the range of 1.50-2.68 g/cm3 and porosity of 0-50%, indicating secondary porosity. This research is an experimental study that aims to analyze and valuate the physical properties of rocks in the Maros Pangkep Karst Area. Rock compressive strength testing shows that the rock in the area has weak strength quality with a range of values of 5-25 MPa and medium strength quality with a value range of 25-50 MPa. Rock density is in the range of values 2.2-2.7 gr/cm ³. The results obtained by the rock type at the site are dolomite limestone with a porosity range value of 0–5% and a modified limestone with a porosity range value of 5–50%. The number of samples used 10 rock samples with a minimum distance of each sample ± 10 meters using a random method. The testing of physical and mechanical properties was carried out to obtain rock conditions and quality using engineering methods. This study aims to determine the value of porosity, density and rock compressive strength values in the karst region of the Pangkep Regency. Analysis of physical and mechanical properties is important to know. The formation of karst from the process of dissolving water against carbonate rocks.
