Abstract

Liquid waste originating from the silver crafts industry is heavy metal waste that is dangerous for the surrounding environment, one of which is copper (Cu). Copper is a heavy metal that can have toxic effects on human health. Based on these problems, processing is needed to reduce the pollutants produced. One of the technologies used is adsorption using a natural adsorbent that is efficient and easy to obtain, namely tofu dregs. Adsorption using tofu dregs is because tofu contains protein. This protein has the ability to absorb amino acids which form two charged ions (zwitter ions). Toxic metals can be bound to proteins as metallothionein. This research aims to determine the efficiency of using tofu dregs as an absorbent for copper metal (Cu) and to determine the effect of contact time and adsorption isotherms on copper metal adsorption. 1 gram of tofu dregs was used with 25 ml of waste and then contacted with a magnetic plate stirrer at varying times of 30, 60, 90, 120 and 150 minutes. The concentrations of all copper metals were analyzed using an Atomic Absorption Spectrophotometer. Next, each copper metal content was calculated using a copper metal standard calibration curve. Identification using an Infrared Spectrophotometer showed that the tofu dregs waste in this study contained the functional groups -OH, N-H (stretching), C-H (aliphatic), C=O, -OH (bending vibration), and C-O. From the research it was found that the copper metal content in the sample was 19.5979 ppm. The optimum contact time for copper metal adsorption is 120 minutes, which results in an optimum adsorption efficiency for copper metal, namely 54.88%. The isotherm equation that corresponds to the adsorption of copper metal using tofu dregs waste is the Freundlich isotherm with a Kf value of 0.072 L/g and a 1/n value of 2.366. This shows that the adsorption of copper metal occurs in a multilayer layer on the surface of the tofu dregs adsorbent, which illustrates the occurrence of physical adsorption. Tofu dregs waste is an effective adsorbent for reducing copper metal levels in silver craft waste.

Abstract

The quality of borehole water is often affected by the high content of Total Dissolved Solids (TDS) which can disrupt human health and quality of life. This study examines the effectiveness of the combination of venturi aeration and slow sand filter technology in reducing TDS levels in boreholes in East Lombok, NTB. The priority is the use of venturi aeration and slow sand filtration in an integrated manner as a combined treatment for borehole water, which has not been widely explored in previous studies. This method offers a practical, cost-effective, and environmentally friendly solution to overcome high TDS levels, especially in rural areas and areas with limited resources. These findings provide a new perspective on optimizing water treatment technologies to improve community access to clean and safe water. Sampling was carried out from six different locations and initial TDS levels were measured. The borehole water was treated through venturi aeration for 1 hour to remove dissolved gases and organic compounds, followed by filtration using a slow sand filter to filter fine particles, microorganisms, and other dissolved compounds. The results showed that venturi aeration was able to reduce TDS by 6.8% to 17.9%, while the slow sand filter provided an additional reduction of 3.1% to 8.3%. The combination of these two methods resulted in a total reduction in TDS of 11.3% to 25.8%. The effectiveness of the treatment was influenced by the iron content in the air and the structure of the sand media. Data were analyzed using the ANOVA test to determine the significance of the reduction in TDS.

Abstract

Dug wells serve as the main household water source for communities in the Kayangan Health Center area of North Lombok, making their structural integrity essential for ensuring safe water access. This study aimed to examine the relationship between dug well construction and the physical quality of clean water. An observational analytic study with a cross-sectional design was conducted from April to June 2024. From a total population of 82 dug wells, 45 wells were selected as study samples using the Slovin formula with a 10% margin of error and simple random sampling to ensure equal selection probability. Well construction characteristics were assessed through direct field observation using a structured checklist based on Indonesian Ministry of Health standards. Physical water quality was evaluated through organoleptic testing of color, odor, and taste in accordance with national clean water regulations. The results showed that 88.9% of dug wells did not meet recommended construction requirements, particularly regarding parapet height, well lining, and watertight flooring. Physical testing indicated that 80% of water samples met quality standards, while 20% failed to meet one or more indicators. Statistical analysis using the Chi-Square test revealed no significant association between well construction and physical water quality (p = 0.258). These findings suggest that physical indicators alone may not adequately reflect contamination risks, highlighting the need for comprehensive water quality monitoring that includes microbiological and chemical assessments to ensure groundwater safety.
