Estimating the Availability of Underground River Water Based on Rainfall in the Maros Karst Region, South Sulawesi

The Unhas KKN-PPM program aims to provide a comprehensive understanding to local communities, who live in the Rammang-Rammang Karst tourist attraction area in Salenrang Village, Maros Regency, about the importance of standardization and certification of tourism businesses so that the Rammang-Rammang Karst tourism object can be managed by the community. locally professionally. In addition, this program also aims to provide assistance to the local community to communicate their needs related to the procurement of more complete tourism facilities and infrastructure to the Regional Government of Maros Regency and the Regional Government of South Sulawesi Province. The mission to be achieved is that the community is expected to be able to actively participate in the development and promotion of tourism in the Rammang-Rammang Karst tourist attraction so that later it can make this destination an international tourism destination that brings in many foreign tourists. With this, the potential and economic contribution of the Rammang-Rammang Karst tourism object can be maximized for the welfare of local communities and increasing state income.

Abstract Aeromonas hydrophila is a valuable indicator of the quality of water polluted by sewage and pathogens that pose a risk for humans and cold-blooded animals, including fi sh. The main aim of this research was to evaluate anthropogenic pollution of river water based on genetic diversity of 82 A. hydrophila strains by means of RAPD, semi-random AP-PCR (ISJ) and the rep-BOX conservative repeats test. Genetic diversity of A. hydrophila was HT = 0.28 (SD = 0.02) for all DNA markers (RAPD, semi random and rep-BOX). None of the analyzed electrophoretic patterns was identical, implying that there were many sources of strain transmission. The presence of genes for aerolysin (aerA), hemolysin (ahh1) and the cytotoxic enzyme complex (AHCYTOGEN) was verifi ed for all tested strains, and drug resistance patterns for tetracycline, enrofl oxacin and erythromycin were determined. The most diverse A. hydrophila strains isolated from river water were susceptible to enrofl oxacine (HS = 0.27), whereas less diverse strains were susceptible to erythromycin (HS = 0.24). The presence of the multidrug resistance marker (ISJ4-25; 1100 bp locus) in the examined strains (resistant to three analyzed drugs) indicates that intensive fi sh cultivation affects the microbiological quality of river water.

As one of greenhouse gases, CO2 content in rainfall is has correlation with CO2 contentin atmosphere. The higher content of CO2 in rainfall will accelerate dissolution processin karst landscape. The aims of this research are to define water quality of rainfall, to determinewater quality of underground river in Bribin, and to analyze the trend of CO2content in rainfall and CO2 content in underground river. Water quality measurements ofrainfall and underground river in karst area was performed during one year in dry seasonand rainy season to compare the rainfall contribution in CO2 content in undergroundriver of Bribin.Based on the result of this research shows that rainfall accelerate CO2 content in undergroundriver that resultintensive dissolution in karst area of Bribin.Water-rock-gas interactionis used to define CO2 contribution from rainfall. Dissolution process is much intensivein rainy season that shows dominant water-rock-gas interaction due to dilution byMiscellaneous topics 193precipitation. In the end of rainy season, the influence of rainfallas the contribution ofCO2 content in river is much less. In dry season, the dominant process in river iswaterrockinteraction due to lack of CO2 from rainfall so that dissolution process will be decreased.
