Abstract

An assesment of the quality of refill drinking water (gallon water) has been carried out. The purpose of this study is to determine the quality of drinking water consumed by people in Samata-Gowa. There were five water samples taken from five residents' houses. The method used were testing physical and chemical parameters. These two methods consisted of temperature, color, odor, and taste tests; biological test with simple method; chemical test using tea water; pH meter test (acidity); conductivity test; and assay for Pb and Fe metal levels using AAS (Atomic Absorption Spectrophotometer). The results obtained included that the temperature of the five samples was in the range of 23.0 °C-27.0 °C, there were showing no turbidity/colorless, odorless, and bland taste; biological test of each sample showed no precipitate formed; chemical tests on the five samples indicated that there were no change in color; pH and conductivity values ranged from 7.5-8.79 and 65.2-109.3 S/cm, respectively; Fe and Pb levels in each sample were 0.0-0.1 mg/mL and 0.05-0.08 mg/L. Based on these data, the quality of refill drinking water for the people of Gowa-Samata is still suitable for consumption because some of these parameters qualified the standards.

Abstract

A study has been conducted on the utilization of activated carbon from palmyra flower waste (Borassus flabellifer L.) as an adsorbent for rhodamine B dye. The purpose of this study was to determine the optimum conditions for activated carbon from palmyra flower waste activated with phosphoric acid (H3PO4) in the adsorption process of Rhodamine B. The preparation of activated carbon from palmyra flower was carried out using the clin drum method. The adsorption process was carried out with variations in contact time and adsorbate concentration. The optimum conditions for the adsorption process of rhodamine B dye were obtained at a contact time of 90 minutes and an adsorbate concentration of 30 ppm with adsorption efficiency values of 50.22% and 77.13%, respectively.
