Abstract
The aim of this study was to create a practical water filter to improve the quality of Muara Angke well water. There are three main steps in this research, namely initial testing of Muara Angke residents^ well water, making water filters, and testing filtered well water. There are three types of tests carried out, namely resistivity, pH, and turbidity. The water filter uses sedimentation techniques using natural materials. The composition of the materials from top to bottom is gravel (30 cm), silica sand (40 cm), manganese zeolite (40 cm), and activated carbon (40 cm). Well water, whether filtered or not, still contains more dissolved ions which causes its resistivity to be lower than bottled water. The filtration process using silica sand, manganese sand, and activated carbon does not directly cause a significant decrease in pH. However, if the source water has certain chemical characteristics or there are reactions that result in increased acidity (such as from CO₂- or oxidation reactions), the pH of the water may decrease slightly. The filtration media used helps reduce water turbidity, but has not reached the desired standard.
