Abstract

Leang Lonrong Cave with underground river flowing in it is located in MarosPangkep karst area known with a high level of annual rainfall. That condition affects the surrounding environment including water discharge and subsurface mineral types. This study aims at analyzing the impact of rainfall on sub-surface mineral types around the area of Leang Lonrong Cave. The data used are rainfall intensity of Tondong Tallasa, Bungoro and Ballocci stations in 2015-2019 which are analyzed using Oldeman and Schmidt-Ferguson methods to find out the characteristics of rainfall occuring in Pangkep Regency. As for water discharge in June 2020 and rock resistivity data, they are examined using geo-electric method by Wenner’s through IP2Win and Res2DinV. The results of this study show that the area is dominated by wet months in November to April with rainfall intensity above 100mm per year and dry months which generally occurring in July to September where the others are considered as humid months with low water discharge flows in dry months. Moreover, the subsurface minerals are dominated by groundwater, clay and sand with resistivity extends from 0 to 27Ωm.
