Abstract

Water is a source of necessity for humans. Water quality is very important to be considered as the source of clean water. Some people in Maros Baru District use ground wells as the source of water needs. Therefore it is important to know the physical quality and pH level of shallow wells and to know the worthiness of shallow wells in Maros Baru District with reference to Permenkes No.492/ 2010. This study examined the feasibility of water based on the physical quality and the pH level of water taken from shallow wells. The research was carried out directly in field with 14 sampling points scattered in the north, east, south, west and at the center of field. The method in observing pH value is by litmus paper and observation on the physical condition of water, well depth, well diameter and surface level of water. The result shows there were 2 locations with saltwater taste, as the location is near from the sea and rivers, while turbidity of the water influenced by condition of surround environment that was not properly maintained. From data processing, it can be concluded that as many as 5 of the 14 sampling points did not meet the eligibility standards of Permenkes No.492/2010 to be used as a source of clean water intended for drinking water.

Abstract

Geothermal is a natural resource energy in the form of hot water or steam that forms in reservoirs within the earth through the heating of subsurface water by hot igneous rocks. Based on field surveys, the Sulili area shows characteristics of geothermal energy in the form of hot springs. The research aims to use the Na-K geothermometer to find out the temperature of the geothermal reservoir below the ground and the Na-K-Mg geothermometer to look into the type of fluid that is in the geothermal reservoir. The research employs the geochemical analysis method in conjunction with the Na-K geothermometer method. Reservoir subsurface temperature is estimated at EPU station 1 at 326.504°C, EPU station 2 at 473.369°C, and station EPU 3 at 456.508°C. According to the results, the hot springs at the three sites are chlorides with temperatures below ground that are part of the high-temperature geothermal system and are >225°C. The hot spring is in the immature water group. Based on the calculation, the Sulili Geothermal Field with an average reservoir temperature of 418°C is approximately 68.33 MWh. This is a simplified calculation, and actual energy output can vary based on several factors, including the specific characteristics of the geothermal reservoir and the efficiency of the power plant.
